Project 70E modified Sverdlov class cruiser
Dzerzhinsky in the Mediterranean on 3 April 1970. Completed in
1952 as a light cruiser (Project 68bis), she was rebuilt with in
the early 1960's with an M-2 Volkhov SAM system (NATO SA-N-2
'Guideline') replacing her aft turrets. She was an active unit of
the Black Sea Fleet until her 1987 decommissioning, frequently
deploying to the Mediterranean.

These ships
engendered alarm in the naval officials of the Western powers, as
they were perceived as significant threats. Although powerful in
appearance, however, the Sverdlov-class cruisers were rendered
largely obsolete by the beginning of the missile age. The Admiral
Nakhimov and Dzerzhinski were refitted in the late 1950s to test
early Soviet SSM batteries. The former unit was scrapped in 1961.
The Ordzhonikidze was sold to Indonesia the following year and
sold for scrap in 1972. All the other units except one were
scrapped by 1994. The Mikhail Kutuzov was put in reserve in 1989
and remains in that status.
The Soviet Union led the way in the development of new cruisers. In 1950, Stalin, despite enduring economic problems, instituted a 10-year construction program that included 40 cruisers, being a collection of battle cruisers, heavy cruisers, and light cruisers. His goal was the restoration of the navy, after it had largely languished during the war, in order to match the naval strength of the Western powers. Construction on the first units was already under way as Stalin initiated the plan. These were the 14 light cruisers of the Sverdlov class. Production of these imposing vessels began in 1949; the final ship was not ready for sea until 1955. The Sverdlov-class light cruisers measured 689 feet by 72 feet, 2 inches, displaced 16,000 tons, and were protected by a combination of light belt and deck armor. Their primary armament consisted of 12 5.98-inch guns in four triplegunned turrets, two each located fore and aft. They also mounted smaller secondary guns and lighter antiaircraft weapons. These batteries benefited from radar equipment for calculating ranges to targets. Their engines could produce a maximum 32.5 knots. Between 1951 and 1952, work on further ships in the plan began when the keels of the two battle cruisers of the Stalingrad-class were laid down. The design called for vessels that measured 836 feet, 8 inches by 103 feet and displaced 40,000 tons. Their primary armament was projected as six 12-inch guns.
As production on the Stalingrad-class battle cruisers commenced, the first of the Sverdlov-class light cruisers were appearing on the world’s oceans. They made a deep impression on naval officials in the United States and Western Europe, who viewed them as a significant threat. The United States responded with the last cruisers whose construction had commenced during the war. Great Britain, owing to economic difficulties that plagued the other Western powers, was the only U.S. ally that built cruisers at the same time as the Soviet ships. These were the three light cruisers of the Tiger-class. Like the U.S. vessels, these ships were based on a wartime design. Owing to economic problems and the need to redesign them for newer detection systems, the first unit was not ready for service until 1959.
The continued justification for gun cruisers, however, was negated by further technological innovation in the Soviet Union between 1962 and 1969 that challenged the U.S. lead in guided missile cruiser design. Following World War II, Stalin had concentrated on constructing a navy that could defend the coasts of the Soviet Union and a few large vessels that could project power further overseas. These larger vessels were armed solely with guns. Upon Stalin’s death in 1953, successor Nikita Khrushchev shifted the priorities of the Soviet surface navy toward the incorporation of missiles. He recognized that the advent of the missile cruiser would ultimately lead to the gun cruiser’s obsolescence. Indeed, he believed that the sole priority of the Soviet Union should be the production of nuclear missile technology. A reflection of Khrushchev’s beliefs was the decision to end construction of the Stalingrad-class battle cruisers. He also characterized the units of the Sverdlov-class, although production continued, as “floating coffins.” New cruiser designs were subsequently drawn up under the direction of Sergei Gorshkov, commander in chief of the navy since 1956, and relied on the Soviet missile program for their armament.
The Soviet program, like that of the United States, had begun in earnest in the months following the end of World War II with the acquisition of German rocket technology. Soviet experiments with German equipment eventually produced missiles in the mid–1950s that alarmed Western powers; increasingly the Soviet Navy posed a greater strategic threat through missile deployment. In September 1955, the Soviet Union became the first nation to fire a submarine launched ballistic missile (SLBM), a weapon that could carry a nuclear warhead and deliver it to a target hundreds of miles away. The Soviets also produced the first conventionally powered ballistic missile submarine in 1958. At the same time, the Soviets were in the process of developing missile systems for surface ships. In the late 1950s, the Sverdlov-class cruiser Dzerzhinski was refitted to test the first-generation Soviet SAM batteries.
Experiments were also under way for the world’s first surface-to-surface missile (SSM) for use against other vessels. This latter type was the result of the need for an offensive capability against NATO aircraft carriers owing to the fact that the Soviet Union had no seabased airpower. Soviet officials viewed Western aircraft carriers as a threat to the Soviet Union itself, as they could launch aircraft armed with nuclear weapons against Soviet military sites and cities. Another Sverdlov-class cruiser, Admiral Nakhimov, was refitted to test the first of the SSM systems, SS-N–1, in the late 1950s.

Although the term “weapon of mass destruction” (WMD) has been in use for more than thirty-five years, it has no widely accepted definition. Only one international agreement uses the term: The 1967 Outer Space Treaty bans “nuclear weapons or any other kinds of weapons of mass destruction” from Earth orbit or on celestial bodies. The term “WMD” sometimes is used to identify weapons considered beyond civilized norms that should be banned or at least internationally controlled.
One working definition for WMD might be weapons that can create more than a hundred times the casualties expected from an equivalent mass of high explosive and that can cause severe contamination to an area requiring millions of dollars and months of work in cleanup and rebuilding efforts in order for safe use to resume. Most definitions of WMD list biological, chemical, radiological, or nuclear weapons. These four types of weapons can affect large areas and large numbers of people, especially in comparison with conventional weapons targeted at specific soldiers, vehicles, or buildings. In addition, all four can produce effects that spread far beyond their original target area and contaminate a large area for a long time after use.
WMD Effects
There are significant differences among the four kinds of WMD in terms of effects, difficulty of acquisition and delivery, and expectations about use. Nuclear weapons are the only type of WMD that destroy structures and equipment as well as killing people. No form of protection is effective against nuclear blast effects.
Pound for pound, biological weapons can produce even more casualties than nuclear weapons, but biological weapons are more dependent on environmental conditions and random factors. With sufficient warning, military forces can protect themselves against biological weapons; for many agents, civilian populations also can be treated after an attack is discovered. Biological agents do not usually produce instant death or even incapacitation; they often take hours or days to produce effects. Some people may even have natural immunity to a biological agent.
Chemical weapons must be delivered in vast quantities to cause massive casualties. When warned, military authorities can have troops use protective gear to reduce the number of casualties suffered during a chemical weapons attack. When not protected, however, exposed individuals may experience a nearly instant agonizing death from just drops of certain chemical agents.
Radiological weapons might produce more panic from fear of radiation than actual death. In theory, radioactive debris could be spread over a large area using conventional explosives laced with fissile material. Radiological weapons require large quantities of material to produce a delayed effect that can be defeated with protective clothing and through decontamination efforts.
Acquisition and Delivery
Nuclear weapons are probably the most difficult type of WMD to acquire because specialized equipment and knowledge is required to develop and test them. Nuclear weapons production relies on complex and unique equipment and the procurement of weapons-grade fissionable materials that must be carefully controlled. Meeting the requirements to construct nuclear weapons is a challenge for nations and may be beyond the ability of nonstate groups. Terrorist groups, however, may be able to acquire a weapon on the black market or through theft.
In contrast, biological weapons can be created using commercial equipment in a relatively small facility, and even small amounts can be deadly. They can be distributed easily, as shown in the U.S. anthrax attacks that occurred in the fall of 2001. Production of chemical weapons in quantity requires chemical engineering expertise and chemical production facilities on a scale similar to that of petroleum refineries. Aircraft sprayers and artillery delivery are preferred for battlefield use, but pressurized tanks can suffice at any scale.
Radioactive material suitable for radiological weapons is readily available given its widespread use in medical and research applications. Delivery of radiological weapons by means of aerial dusting would affect the largest possible area, but recent concern has centered on the possible terrorist employment of so-called dirty bombs, that is, conventional explosive devices used for dispersing nuclear material. Explosive dispersal is unlikely to produce any deaths from radiation but could require an expensive and time-consuming decontamination cleanup effort to make the area safe for human occupation.
Despite the potential for chemical, biological, radiological, and nuclear weapons to produce large-scale death and destruction, weapons of mass destruction have primarily served as tools of deterrence by nations attempting to prevent their use by adversaries.

The
substance known as “red mercury,” purportedly a mystery
ingredient in Soviet pure fusion weapons, gained both U.S.
congressional and worldwide media attention in the wake of the
1991 collapse of the Soviet Union when it began appearing on the
nuclear materials black market. The red mercury furor began over
reports that the Soviet Union had perfected a pure fusion nuclear
warhead, which reportedly relied on heavy hydrogen—deuterium
and lithium isotopes—as its fuel.
It is
said that under the proper heat and pressure, the lithium and
deuterium isotopes fuse, releasing high-energy neutrons that kill
living matter in their path. Identified by traffickers with the
composition Hg2SB2O7 (that is, a combination of mercury, sulphur,
boron, and oxygen), red mercury has since been surmised to be the
Russian code name for lithium deuteride, Li6D, a legitimate
component in thermonuclear weapon production, or the heavy metal
osmium.
Though
there are some detractors who insist that red mercury is
legitimate, much of the nuclear scientific community has stepped
forward to discredit it as an important component in pure fusion
weaponry. Instead, it is generally accepted that red mercury was
touted by intelligence organizations or criminals as a weapons
material to hoodwink terrorists and states with nuclear
ambitions. Reports of it appearing on the nuclear black market
have become less frequent in recent years.

First seen in late 1987, the Wuhan 351 is a modified Romeo Class
(Type 033G) (SSG), designated ES5G, converted as a trials
anti-ship missile platform. The project was probably inspired by
the Cold War era conventional-powered Russian Juliette class
cruise missile submarine. The Wuhan 351's structure consist of
six missile launcher tubes which are built into the casing
abreast the conning tower and elevated to fire. To provide target
acquisition an additional radar mast (Snoop Tray) is mounted
between the two periscopes. It uses Pike Jaw or Hercules, hull
mounted, search and attack, medium frequency sonar.
The Wuhan 351's primary weapon system consist of 6 missile
launchers, 3x launchers on either side of the conning tower. Each
of those watertight launcher tubes carries a single C-801
anti-ship missile. The C-801 incorporates technologies such as
inertial cruise, active radar homing sea-skimmer with 40 km (22
nautical miles) range at 0.9 Mach. The C-801 may soon be replaced
by C-802. The secondary weapon system consist of 8x 533mm torpedo
tubes with 14 torpedoes or 28 mines. The submarine has to surface
to fire missiles, although trials are reported to implement an
encapsulated missile which can be launched from the torpedo tube
while submerged. Based in the North Sea Fleet and reported still
doing trials in 1999. Clearly there is no intention to fit this
type of missile tube in other classes.

The amphibious Jeep or Seep was inspired by the much larger DUKW.
More properly it is a Ford GPA (G: Government, P: 80" wheelbase,
A: Amphibian), based on the standard world war II Jeep. A simple
hull was wrapped around the Jeep chassis. A propeller is driven
from the transfer-case power take off unit. The other "propeller"
shafts to the front and rear axles are enclosed in water proof
tubes, sealed by flexible gaiters to the hull and to the
differentials to allow normal suspension movement. These and
other modification pushed the weight up to 1600kg (3600lbs). The
cockpit has more control levers than you can poke a stick at:
2WD/4WD, hi-range/ lo-range, capstan winch (on the bows), rudder
and propeller.
The Seep's intended use was to ferry soldiers to and from ships
off-shore, to trundle up the beach and continue inland. They were
not very successful. It had been planned to build 12,000 of them
(Clayton '82) but only 5,000 were produced (Carlin '89), all by
Ford. It is reported that many of the Jeeps that were used in
battle sank if there were any significant waves at all.
Nevertheless, a highly modified amphibious Jeep called
`Half-Safe' crossed the Atlantic Ocean in 1950 and continued on
to circle the world

T-34-85 equipped with stand-off screens to protect thinner side
and top armour from the HEAT warheads of Panzerfausts during
street fighting. These particular shields were constructed from
5–8 mm (0.2–0.3 in) steel wire. Berlin, May 1945.
In the Berlin operation, Soviet units did devise simple mesh
screens which could be welded to the tank's exterior to detonate
the Panzerfaust warheads prematurely (so-called bedstead armor,
but most were fabricated from screening and angle irons, not
actual bedsteads).

Various users!
The Pe 2 was Russia’s outstanding tactical bomber of World
War II and distinguished itself throughout that conflict. Even
when fully loaded, it flew so fast that escorting fighters were
hard-pressed to keep up.
In 1938 a design bureau under Vladimir Petlyakov responded to
Soviet specifications for a high-altitude fighter with the VI
100. It was an all-metal, twin-engine machine with two rudders
and streamlined engine nacelles. A crew of three sat in a
spacious cockpit toward the front of the fuselage. In designing
the VI 100, careful consideration was given to weight and drag
reduction, so bulky radiators were located along the wings
while the fuselage employed the smallest possible
cross-section. Flight-testing commenced in 1939 with excellent
results, but the government changed the role of the craft to
high-level bombing. When this proved impractical due to
inaccuracy, dive-bombing was substituted, and the plane was
fitted with dive brakes. Petlyakov’s design proved successful
in this mode, and in 1940 it entered service as the Pe 2.
When war with Germany commenced in June 1941, Pe 2s
distinguished themselves in hard-pressed attacks and flew
faster than pursuing Bf 109E fighters. Pe 2s were so speedy
that they frequently throttled back to allow Lend-Lease Hawker
Hurricane escort fighters to keep up. The Pe 2 was also quite
strong and could sustain major damage with few ill effects.
Successive modifications and stronger engines improved
performance and kept them slightly beyond the reach of the
newer Bf 109F/Gs. The biggest modifications occurred in 1943,
when the wing profile was modified, oil-cooler intakes were
reshaped, and bomb mounts received streamlined fairings. The
net result was a 25 percent increase in speed. Features to
enhance crew survival were also incorporated, including a novel
cold-gas bleeding system to suppress fires in the fuel tanks.
No less than 11,400 of these impressive machines were
constructed. In concert with the smaller Ilyushin Il 2, they
were significant contributors to the final Russian
victory.

Welcome to the official website for the Mercenaries Medieval
Combat Guild.
The Mercenaries Medieval Combat Guild, or “The Mercenaries”
was created on February 15, 1994 in Colorado Springs, Colorado.
It is a non-profit group and has as its mission:
“The Mission of the MMCG is to revive the combat skills of the European Middle Ages (circa 800-1500 A.D.), to further research and accurately depict all aspects of medieval culture, and to create an enjoyable experience for its members.”
Essentially, we
are a group dedicated to the safe re-creation of medieval combat.
We strive to be accurate in representation of clothing, weapons,
armor, techniques, philosophies, and technical skills. In order
to maintain our mission, we have created these
goals:
While we are
dedicated to being as accurate as possible, we do not require
that our members confine themselves to a certain geographical
area or specific time within the 700 year period of the Middle
Ages so long as they make a genuine effort to “look the part."
We have no desire to exclude those who are unable, either through
financial or time constraints, to re-create exact replicas of the
clothing or artifacts needed to participate. We are not a
“live-role-playing” group and we restrict our members to the
real world and do not allow fantasy elements such as magic or
personas that are not human. This website is intended to act as a
resource for members of the group and for those wishing to know
more about our group. If you are interested in more information
concerning the Mercenaries Medieval Combat Guild, or would like
to attend one of our events, please refer to the contact

goedendag
Staff weapons, used both by foot and equestrian soldiers, are of great antiquity, but the period from 1300 was when they especially came into their own as an infantry weapon. In 1302, at the Battle of Courtrai, the Flemish townsmen from Bruges, Ypres, and Courtrai, armed, in the main, with staff weapons routed a superior and supposedly better-armed French army. The reaction to this victory, essentially by the lower and middle classes, and the large numbers of French cavalry dead, were noted throughout Europe and caused uproar among the nobles, knights, and the upper classes of society. The weapon, called a goedendag (literally “good morning” or “good day”), which caused such a devastating and unexpected victory, far from being sophisticated or innovative, was basically a heavy-headed club to which iron spikes were attached. Their use at Courtrai and, equally important, the discipline of the Flemish forces, mark the rise of the infantry armed with staff weapons as a potent force on the battlefields of Europe. This victory was followed by that of the Swiss using staff weapons at the battle of Morgarten against the Austrians in 1315. From this time on staff weapons played an increasingly important part on the battlefield—blocks of disciplined, well-trained, and well-drilled infantry, all armed with similar weapons, were common down to the seventeenth century.
The traditional infantry weapon, the spear or long spear as it became known in the fourteenth century, was around 15 to 18 feet long (5 to 6 meters) and was essentially a defensive weapon. It was used to extend the reach of the foot soldier in a thrusting motion that, when well directed, was effective against other infantry and mounted troops, especially when used in closely ordered formations. By the beginning of the fourteenth century, the spear had been joined, as already described, by other forms of staff weapons, in particular the goedendag. However, the increase in the use of armor, especially the development of the full-plate harness, led to the need for an infantry weapon that was capable of both thrusting and cutting actions. Essentially, the ability of plate armor to resist penetration, coupled with its smooth, rounded surfaces, which tended to deflect blows, meant that the thrusting spear was less effective. From the very end of the thirteenth century, there developed a new type of staff weapon, the halberd, which combined the spear with the long, two-handed axe. At first it consisted of a fairly broad blade with a spike projecting from the top secured to the end of a long pole— around 6 feet (2 meters) in length. It was used in a similar way to the spear as a thrusting weapon, but it could also be swung over the head and brought down with considerable force. During the fifteenth century, an extra spike was added to the axe portion of the head making it an even more formidable weapon.
The halberd is most closely associated with the Swiss armies of the later thirteenth and, especially, the fourteenth and fifteenth centuries. The Swiss had been granted rights of freedom, which carried with them the right to bear arms, and this resulted in a population that carried weapons as a norm of everyday life. This familiarity with arms, especially staff weapons, resulted in the creation of a voluntary, part-time army that was both well disciplined and skilled. And, in fact, Swiss mercenaries gained a considerable reputation all over Europe during the fifteenth and early sixteenth centuries and were much sought after by military leaders and commanders. By the end of the fifteenth century, a very characteristic Swiss halberd had developed, although it is important to note that it was not just the weapon that made the Swiss such a formidable force but discipline and the ability to fight as a unit.
The halberd and the goedendag were joined by a variety of other staff weapons over this period, some very characteristic of particular areas and some more widely distributed around Europe. The glaive, a large cutting and thrusting weapon, had a long blade with a convex front edge and a straight back. Although it was never very common, it probably first appeared in Europe during the thirteenth century and was used throughout the end of the Middle Ages. Later, in the sixteenth century, it came to be used very much as a ceremonial weapon carried by official guards and in processions. The bill was far more commonly used throughout Europe in the later medieval period. Although there were considerable variations in its form, it generally consisted of a forward-facing hook with one or more spikes projecting from the rear and/or front. Simpler bills were very similar to halberds and were probably used in much the same way. Other, more complex types were developed. For example, the Welsh bill had a long slender curved blade and a right-angle spike, and the roncone, developed in Italy, had a long straight blade with a smaller curved hook and both top and backward-facing spikes. Finally, the partisan, a later type of staff weapon used throughout Europe from about 1500, was basically a long, flat blade tapering to a point, rather like an elongated spear.

The conical case of the lunge mine is made of unpainted steel.
Three legs attached to the base give a stand-off of 6 inches. At
the apex is either a standard grenade-detonator or a primer cap,
safety fuze, and detonator. Screwed to the apex is a metal tube
containing a long wooden pole with a pointed striker at the lower
end. The pole and striker are held away from the detonator by a
safety pin and a copper shear wire. The liner of the cone is made
of aluminum or steel.
After removing the safety pin, the attacker hinges forward toward
the target, with sufficient force to shear the shear wire and
drive the striker into the cap. It is reported that this mine is
capable of penetrating 6 inches of armor plate with head-on
contact, while 4 inches can be pierced by contact at a 60-degree
angle.
SPECIFICATIONS:
Weight of mine body - 11.8 pounds.
Weight of charge - 6.40 pounds.
Length of mine body - 11 inches.
Diameter at base - 8 inches.
Length of handle 76 inches.
Internal height of shaped-charge cone - 4.5 inches.
Bottom diameter of cone - 3.7 inches.
Apex angle – 40*
Individual Suicide Attacks
Japanese antitank methods include considerable individual action
by Japanese soldiers in suicidal missions. In one instance, a
Japanese soldier dug a well-camouflaged fox hole among the weeds
just off the shoulder of a road barely two traffic lanes wide. A
tape-measure mine was tied to the end of a 5-foot bamboo pole.
Lying in the protection of the fox hole, the soldier waited for a
chance to push the mine under the tracks of any Allied tank using
the road. Another one-man attack method uses the lunge mine,
which consists of an armor-piercing charge placed on the end of a
pole. The attacker waits in hiding and lunges at the first tank
to draw near with his mine and pole held in much the same manner
as a rifle with fixed bayonet. The mine explodes on contact.
A demolition charge, manually attached to an Allied tank and hand
detonated, is another suicide weapon employed by the Japanese.
Filled with 10% pounds of picric acid, a wooden box about 8 to 10
inches square is mounted on a wooden base and slung over the back
of the soldier. The outside perimeter of the box is fringed with
hooks by which the tank raider hangs the demolition charge on the
turret or any other part of the Allied tank. A Type 91 or 97 hand
grenade is used as a detonator. After the box is attached to the
tank, the fuze head of the grenade is rapped sharply by the tank
hunter; an explosion results immediately.
Another weapon is the shoulder-pack mine. With the mine strapped
to his back, the Japanese conceals himself as close as possible
to the path of the approaching tank. When the tank arrives at a
point about 15 feet from the concealed soldier, he dashes out and
throws himself under it, between the tracks. Ile pulls a
detonating cord when the tank is directly over him. The mine
explodes 1 to 3 seconds after the cord is pulled.
In recent operations in Burma much reliance was placed on one-man
suicide tank-hunting tactics. Types of suicide activities varied.
Soldiers sat in fox holes with aerial bombs between their knees,
prepared to detonate them by hand when an Allied tank pass over.
Attempts were made to place picric acid charges with pull fuzes
on tanks by hand. Hand grenades and Molotov cocktails were thrown
from hiding places in culverts. Other Japanese were reported to
have attempted to set tanks on fire by throwing lighted branches
which had been dipped in oil. One Japanese officer charged a tank
armed only with his sword and succeeded in inflicting
considerable personal injuries on the tank crew.
A report from Okinawa told of Japanese soldiers hidden in
camouflaged holes and armed with explosive charges strapped to
their backs. Success of this antitank ruse required that the
hidden soldiers detonate the charges, using pull igniters, as
Allied tanks pass over the holes.
These tactics illustrate a recently discerned Japanese trend to
resort more and more to the use of individual tank hunters rather
than teams. This practice apparently follows a known decision of
the Japanese Imperial General Staff that tank-assault units can
be used most efficiently if each individual member of such units
acts upon his own initiative in suicide attacks. Tactics are
modified to provide supporting fire for individual attackers in
order to enable them to get within striking distance of their
targets.

The 2A3 Kondensator 2P was a Soviet 406 mm Self-propelled
Howitzer. 2A3 is its GRAU designation.
2A3 originated during the Cold War when the United States
created its new tactical doctrine called Pentomic Division
which emphasized heavy use of nuclear weapons including nuclear
artillery. M-65 was introduced in 1952 and deployed in Germany
in 1953. In response Soviet Union started its own program to
develop a 406mm self-propelled howitzer capable of firing
nuclear projectiles which was codenamed 'Objekt
271'.
Grabin Design Bureau completed the artillery system in 1955.
The 'Objekt 271' chassis by Kotlin Design Bureau in Leningrad
was completed soon thereafter. The unified system received the
military industrial designation 2A3 and was completed in 1956
at the Kirov Works in Leningrad. Total production only amounted
to four vehicles.
Western observers got their first look at the new weapon during
a 1957 parade on Red Square. Initially observers thought that
the weapon was a mockup created for a deterrent
effect.
Kondensator had an exceptionally short service life. Following
a period of extensive testing the weapons were assigned to the
Artillery High Command reserve. There they remained in service
until the military reforms of Nikita Khrushchev were enacted.
Reforms favored more effective missile systems over the
super-heavy artillery and heavy tanks which characterized the
Stalinist era.
All four Kondensator howitzers were retired in the mid-1960s. One of the weapons was placed on static display at the Central Armed Forces Museum in Moscow.

2B1 Oka is a Soviet 420 mm self-propelled mortar. 2B1 is its
GRAU designation. The mammoth 420mm SP Oka mortar system, which
was originally intended to fire tactical nuclear rounds.
An experimental model was ready in 1957. Its chassis (Object
273), was designed and built by the Kirov Plant. Its 20 meter
barrel allowed it to fire 750 kg rounds up to 45 km. Due to its
complexity of loading it had a relatively low rate of fire - 1
round every 5 minutes. Field tests showed various drawbacks of
the entire design (the recoil was too strong for many
components - it damaged drive sprockets, tore away the gear-box
from its mountings, etc). The Oka was built on a T-10
chassis.
Its development continued until 1960, when the idea of such overpowered guns (along with the 2A3), was abandoned in favor of tactical ballistic missiles, such as the 2K6 Luna.
2A3:
Weight - 64000kg
Max speed - 30km/h
Horse power - 750 h.p.
Weight of the HE round - 570kg
Muzzle Velocity - 716m/s
Max Range - 25600m
Rate of fire - 1 round every 5 minutes
2B1 OKA:

Max speed - 30km/h
Weight of the HE round - 750kg (other sources - 650kg)
Max Range - 45000m (other sources - 25000m)
Rate of fire - 1 round every 5 minutes

Type 98 was first used in Singapore and the
Philippines in the early Pacific War. After that, Type 98 was
used on Okinawa and Iwo Jima.
Independent artillery mortar battalions (Dokunitsu Kyoho Daitai) in Burma were issued with a ponderous 320mm Type 98 (M1938) spigot mortar which could throw a 675 lb bomb over 1,000yd. This weapon was clearly akin to the 320mm spigot mortar designed specifically for demolition work. (Few of them were made and they were little used).
In both cases the spigot mortar itself comprised a steel spigot, a domed steel mounting plate — supported by a dome-shaped wooden block, and a steel baseplate; these were all bolted to a heavy wood block base. The spigot was a steel cylinder with a cavity at the upper end for the propellant. The wooden base consisted of three sections of rectangular baulks of timber, the top section, the middle and the bottom sections — alternate sections being laid at right angles to one another.
Provision was made for a limited amount of traverse and the spigot-seating bolts were so constructed as to permit setting up for line. Changes in range were obtained by varying the propellant charge.
Bombs were in three parts which screwed together; an HE warhead fitted with a nose-fuse, a cylindrical central portion with an internal cavity for a secondary filling, and a cylindrical finned tail unit. The primary and augmenting charges were contained in a brass case which fitted into the spigot cavity; ignition was by means of an electric ignitor through a flash channel in the side of the spigot and the bomb tail.

Mario Castoldi had been convinced from the earliest days of MC.200 flight testing that full potential of the design would be achieved only by the installation of an inline engine. This opinion was confirmed during August 1940 when the prototype Macchi MC.202 (MM 445) was tested with an imported Daimler-Benz DB 601A-1 engine. The prototype was first flown on 10 August 1940, and its initial trials were so impressive that it was ordered into production without delay.
Generally similar in overall configuration to the MC.200, the MC.202 Folgore (thunderbolt) introduced a new fuselage structure with an enclosed cockpit, similar wings, but retained the tail unit and landing gear of its predecessor. However, the single MC.202 prototype, which was basically a re-engined MC.200 airframe, was flown with a retractable tailwheel. Because of the degree of commonality there was little delay in starting production, the first deliveries being made in the spring of 1941. Built alongside the MC.200 by Macchi, Breda and SAI-Ambrosini, early series aircraft were powered by imported DB601A-1 engines until such time as Alfa Romeo had a licence-built version in production as the RA.1000 RC.41-1 Monsone (monsoon). However, it was limited manufacture of this engine which restricted the number of MC.202s to a total of about 1,500 when production ended in 1943, and. so the MC.200 continued to be manufactured simultaneously, instead of being supplanted completely by the Folgore. Like its predecessor, the MC.202 was built in generally similar MC.202AS and MC.202CB tropicalised and fighter-bomber variants respectively, plus a single MC.202D experimental aircraft which introduced a revised radiator for the engine cooling system.
Undoubtedly the best wartime fighter to serve in large numbers with the Regia Aeronautica, initial deliveries of production aircraft were made in November 1941 to units operating in Libya. The Folgore also took part in actions against Malta and Allied convoys in the Mediterranean and, in September 1942, was deployed in some numbers on the Eastern Front. They played a significant role in the defence of Sicily and southern Italy against bombing attacks launched by the USAF, but by the time of the Allied invasion of Sicily they were less effective as attrition had reduced the total number available.
Specification
Macchi MC.202
Type: single-seat interceptor fighter
Powerplant: one 1,175-hp (876-kW) Alfa Romeo RA.1000 RC.41-1 Monsone 12-cylinder inverted-Vee piston engine
Performance: maximum speed 370 mph (595 km/h) at 16,405 ft (5000 m); service ceiling 37,730 ft (11500 m); range 475 miles (765 km)
Weight: empty 5,181lb (2350 kg); maximum take-off 6,636 lb (3010 kg)
Dimensions: span 34 ft 8lh in (10.58 m); length 29 ft 0 ½ in (8.85 m); height 9 ft 11 ½ in (3.04 m); wing area 180.84 sq ft (16.80 m2)
Armament: initially two 12.7-mm (0.5-in) Breda-SAFAT machine-guns in upper engine cowling, but later series added two wing-mounted 7.7-mm (0.303-in) Breda-SAFAT guns; one production batch introduced a 20-mm cannon beneath each wing
Operators: Luftwaffe (small number ex-Italian), Italian Regia Aeronautica, Aeronautica Cobelligerante del Sud, and Aeronautica azionale Repubblicana
Variants and production
Like its predecessor C.200, the C.202 had relatively few
modifications, with only 116 modifications during its career,
most of them practically invisible externally. The total series
production ordered was 1,454: 900 to Breda, 150 to SAI
Ambrosini, 403 to Aermacchi. The amount produced was actually
1,106 and not 1,220 as previous stated. Breda built 649 (Series
XVI deleted, Series XII and XV partially completed caused the
difference); Aermacchi made 390 examples, SAI only
67.
One of the differences between prototype and series production
was the lack of radio antenna and the retractable tailwheel
(these differences caused the slightly advantage in speed); the
difference in speed was not so great and so, the series version
had the fixed tailwheel and the radio antenna. However, the
support for the engine, originally made in steel, was replaced
with a lighter aluminium structure.
C.202
Starting with the Serie VII, the fighter had a new wing with a
provision for two 7.7 mm (.303 in) Breda-SAFAT machine guns and
an armoured windscreen (previously, only the armoured seat and
the self-sealing tanks were provided). Serie IX's weight was
2,515/3,069 kg with the 7.7 machine guns seldom
installed.[36]
C.202AS
Dust filters for operations in North Africa (AS - Africa
Settentrionale, North Africa); they little affected the speed
and so, almost all Folgores had them and thus were in C.202AS
standard; finally, starting with Serie XI there was a provision
for two 50, 100 or 160 kgs bombs, small bombs clusters (10, 15,
20 kg) or 100 l tanks. These underwing pylons were rarely
utilized, as Folgores were needed in the interceptor
roles.
C.202CB
Underwing hardpoints for bombs or drop tanks (CB - Caccia
Bombardiere, Fighter-Bomber)
C.202EC
probably meaning Esperimento Cannoni, it was another linking
ring between Veltro and Folgore. One aircraft (Serie III, s/n
MM 91974) was fitted with a pair of gondola-mounted 20 mm
cannon with 200 rounds each (it flew on 12 May 1943); later it
was turned into a C.205V. Another four examples were so
equipped, but, despite the good results in the trials (aimed to
boost the Folgore's firepower), there was no further
production, because the cannons penalized the aircraft's
performance. There was, in the Folgore, no room to mount them
inside the wings or the nose, so it was developed the
MC.205V/Ns.[38] Neverthless, the XII series could have
introduced a new wing with MG 151 provisions. This is not well
documented, as this series was produced by Breda after the
Armistice, and was interrupted with the devastating USAAF
bombings, together with many others aircraft; among them, also
Macchi 205 production and the 206 prototype (30 April 1944; in
five days, the USAAF managed to destroy both Fiat and Macchi
facilities, eliminating all of Italy's fighter
production).
C.202RF
Equipped with cameras for photo-reconnaissance missions (R -
Ricognizione, Reconnaissance), very few produced, later the
recce role will be couvered by Veltros.
C.202D
Prototype with a revised radiator, under the nose, similar to
the P-40's one (s/n. MM 7768)
C.202 AR.4
at least one was modified as 'drone director' (coupled with
S.79s), and it was planned to use Folgores also as 'Mistel',
with an AR.4 "radiobomba". (a sort of remote-control kamikaze
bomber).
C.202 with DB 605 and other engines
Macchi MC.202 with DB 605 were initially known as MC.202 bis;
later as the C.205 Veltro. Macchi C.200, C.202 and C.205 shared
many common components. The MC.200A/2 was a MC.200 with Folgore
wings (MM.8238). After the Armistice, Aeronautica Sannita or
the Co-Belligerant Italian AF began MC.205 modifying C.202s
with DB 605s. These aircraft were known also as "Folgeltro".
Around two dozen were made. Another Folgore was modified with
DB 601E-1 (1,350 hp) in summer 1944, but this hybrid with
Bf-109F technology crashed on 21 January 1946. The MC. 204 was
a version with a L.121 Asso (1,000 hp); proposed early in the
war (28 September 1940), but all the effort continued only with
DB-601 engines. Early Folgores had original DB 601s, while from
the Serie VII, RC.41s were available. Italian engines had 100
hp less than the German DB 601s.
After the war, 31 C.202 airframes were fitted with license-built Daimler-Benz DB 605 engines and sold to Egypt as C.205 Veltros, with another 11 'real' MC.205s (with MG151 cannons in the wings).
