RE: supplies of V-2-34 diesel engines with a main clutch

To the Deputy People's Commissar of Medium Machinebuilding, comrade Goreglyad
8a Ryazanskaya St.

In response to your letter #16/2291 on March 18th, 1941

The GABTU considers it necessary to deliver the V-2-34 engine together with the main clutch for the following reasons:

The warranty period of the main clutch is seldom higher than the lifespan of the engine: the engine's guaranteed lifespan is 150 hours, the tank travels 2000-2250 km in this time. The existing main clutch needs replacing after this time.

Herald of a Revolution

The decision to mass produce the T-44 medium tank was made in the summer of 1944. This happened not only before the final prototype indexed T-44A was built, but before the GBTU even composed tactical-technical requirements for a new tank based on the combat experience of the first half of 1944. As a result, the tank seemed obsolete before it was even put into production, especially its armament. Work to correct this went in two directions. The first was evolutionary and led to the T-44-100 tank. The second was revolutionary and brought about a deeply modernized T-44 indexed T-54.

Fake Antenna

Soviet tank industry outpaced the electronics industry. As a result, until 1943 "premium" tanks like the T-28, T-35, and KV were all built with radios, while "ordinary" tanks like the T-26, BT, and T-34 did not. About half of these tanks received radios until 1943, after which radios were installed on all tanks.

Even in the Spanish Civil War tankers noticed that the enemy attempted to knock out tanks with large frame antennas first. The introduction of smaller whip antennas made it easier to hide commanders' tanks, but they were still visually distinct. This was resolved in an obvious way.

The Best of the "Varangians"

The first American Lend Lease tanks arrived in the USSR towards the very end of December 1941. The volume of shipments was small at first, but this changed in the spring of 1942. American light and medium tanks began arriving in large amounts and were widely used in battle by that summer. The Medium Tank M3, known as the M3S or M3sr, was the most common American medium tank shipped in 1942, but towards the summer the Americans began to shift production to the more successful Medium Tank M4. Its diesel variant, the Medium Tank M4A2, became the most common foreign tank used by the Red Army.

Indirect Fire

160th Tank Regiment
January 11th, 1944

To the Commander of Armoured and Mechanized Forces of the 63rd Army
RE: your letter #079 dated January 9th, 1944

The azimuth circle and clinometer installed on T-34 tanks for indirect fire were not used in practice by the regiment for the following reasons:
  1. Tank crews do not know how to fire indirectly as they were not trained to do it.
  2. It is unnecessary to use the tanks for indirect fire, as towed and self propelled artillery supporting the tanks' attack handles the mission perfectly well. 
I consider it reasonable to simplify the fighting compartment of the T-34 tank by removing the azimuth circle and clinometer from the T-34 and removing them from service, as the devices have no practical use.

Beefy Sherman

American light and medium tanks had distinctively well balanced characteristics in WWII. The Americans rarely went too far in the armour department, reasoning that the mobility of a tank is one of its most important characteristics. However, the idea of building a tank with improved protection was not alien to them. One of these tanks was the specialized M4A3E2 tank, the best protected medium tank of WWII. Even though few were made, the M4A3E2 fought actively and proved itself to be an effective weapon.

On Water Like On Land

WWII clearly showed the importance of combat and transport vehicles that could cross water hazards. Crossings of rivers, lakes, channels, and reservoirs made planning any military operation more complicated, reduced the rate of offensives, and led to significant losses among attackers. The USSR performed nearly no work on amphibious vehicles for transport or combat. Only T-37, T-38, and T-40 tanks designed for reconnaissance were accepted into service. They were armed only with machine guns and could not effectively support infantry. After the end of the war the USSR began development of a wide variety of amphibious vehicles.

Black Prince

The British military had strange ideas about what a tank should look like in WWII, which led British tank building into a dead end. It's not surprising that the American Stuart tank became the most common light tank in the British army and the most common medium tank was the Sherman. The British were on their own when it came to heavy tanks, as there was no foreign alternative to the Churchill. That didn't stop the British from making several attempts to replace it throughout the war. The Black Prince I was one such attempt. This was a direct descendant of the Churchill tank that came up short compared to its ancestor.

Distorted Tanks

"October _, 1942

To the Chief of Staff of the 1st Motorized Brigade

The Red Army General Staff reports that the German army has the following new types of tanks:
  1. T-5 tank. Weight: 30 tons. Armament: 1 88 mm gun and 2 machine guns.
  2. T-12 tank. Weight: 40 tons. Armament: 1 75 mm gun and 4 machine guns.
  3. V-K-18 tank. Weight: 18 tons. Armament: 1 20 mm gun and 1 machine gun.
Determine the presence of these tanks and their tactical-technical characteristics from interrogation of POWs and captured documents. Report to the 3rd Mechanized Corps on your results. Send captured documents and photographs of these tanks to the 3rd Mechanized Corps.

Chief of Staff of the 3rd Mechanized Corps, Guards Lieutenant Colonel Nikitin."

Looks like a bunch of nonsense based on unverified information that was pretty common, but these descriptions match reality quite well. The T-5 could very well be the VK 30.01(P), which indeed had an 88 mm gun. The T-12 looks more unusual, closer to the fledgeling Panther, which would have reached the weight of about 40 tons in late 1942. Finally, the V-K-18 could be the VK 18.01, but this tank only had machine guns for armament, unlike the similar VK 16.01 which the report could be confusing it with.

Automatic Welding

"Order of the People's Commissar of Tank Production of the USSR #837s

December 19th, 1942

Production using automatic welding under a layer of flux when producing armoured hulls at factory #183, UZTM, etc. proved itself as having several advantages over manual arc welding.

In addition to increased productivity, reduced electricity consumption, and the ability to use untrained workers, the high quality of the seams was proven. During proving grounds trials, they showed better resistance than welds made by hand.

Still With a Cabin

Usually one or two prototypes are built before a tank goes into production with only a few changes. However, there are exceptions. With IS series of tanks there were three of them, two of which were radically different from the final model. The similarly revolutionary T-44 evolved in a similar way. Even without significant changes in requirements,, this tank went through a series of evolutionary steps. The second variant of this vehicle was created as a result of trials held in February-March 1944. One of the main differences of the intermediate prototype was the armour. Trials showed that it was not enough to protect from the 88 mm Pak 43 L/71.

Based on the trials of two T-34 hulls and turrets, the commission finds that:

  1. On the impact of cracks and hot tears around welding on shell resistance:
    1. When shells impact the area of cracking, the cracks grow negligibly. In many cases cracks do not grow.
    2. The presence of cracks or hot tears in 40 or 45 mm thick armour does not decrease robustness, but is still an undesirable defect that is caused by the quality of the armour and welding. Ilyich factory and factory #183 need to develop measures to resolve these defects.
    3. The presence of cracks and hot tears up to 20 mm deep around the weld is unacceptable as they lead to brittle damage to armour when hit. In exceptional cases parts can be permitted with singular cracks or with limited hot tears.

A Step in the Right Direction

Work on a radically new tank often results in the creation of intermediate vehicles. This exact thing happened with Soviet medium tanks in WW2. Several attempts were made to replace the T-34 with modernized vehicles. The first attempt was called T-34M, later the T-43 took a shot at the reigning champion. The results were similar: neither tank replaced the T-34. The first Soviet new generation medium tank, the T-44, travelled a long way and changed a lot before it entered production.

Flamethrower Tanks

"Excerpt from the trip report to the Volkhov Front

The 502nd and 503rd Independent Tank Battalions used flamethrower tanks rarely, but the commanders and crews still praise highly the effect of flamethrowers in battle. For instance, the commissar of the 502nd ITB stated that the flamethrowers were used rarely only because the terrain got in the way and that German infantry flees in advance of the tanks to keep out of range. The effectiveness is high. When flamethrowers are used, the enemy runs from dugouts and abandons everything.

A driver of a KV-8 tank, comrade Paturnak, tells had he made only 4 shots from his flamethrower. An anti-tank gun fired at the tank, but as soon as a flamethrower burst was fired towards the gun the gun crew fled and two Germans fell down in shock and were then crushed by the tank's tracks.

The commander of the 503rd ITB, Captain Drozdov, stated that when using flamethrowers near Gontovaya Lipka the fuel did not reach the enemy positions, but they fled in panic. However, he considers it unreasonable to use flamethrowers in forested swamps.

The commander of the 507th ITB, Major Nikolayevtsev, tells that a KV-8 tank commanded by political coordinator Osatyuk fired 15 shots at infantry hidden in bushes. The infantry fled in panic. A portion of the fascists ran while on fire. One KV-8 tank used flamethrowers at night. The Germans ran in panic, tearing off burning clothes and even underwear.

The commanders of the 507th ITB reported to the 8th Army that "the flamethrowers fulfilled their mission" and later, after a description of drawbacks encountered during exercises near Kuzminka, writes that "after these drawbacks are corrected, this will be an excellent weapon to use against the enemy."

Another report to the same organization states that "the flamethrower is an excellent weapon for use against counterattacking infantry in forested swamps... practice shows that the effect on the enemy at night is terrifying. During an attack on the night of August 30th-31st near point 40.4 and in the sector of the 24th Guards Rifle Division the Germans fled in panic, throwing off their equipment and underwear".

All flamethrower battalions on the Volkhov Front mainly used KV-8 tanks. T-O34 tanks used their flamethrowers rarely."

An Overloaded Big Cat

German tank builders started producing tanks with greater characteristics than those of their competitors since late 1942. First was the Tiger Ausf.E which had no equivalent for over a year. The Panther Ausf.D debuted in the summer of 1943. This tank was even more dangerous, if only because there was more of them. As practice showed, the Panther's gun was more powerful than a Tiger's, and its upper front hull plate was impervious to 76-85 mm guns at any range. The Ferdinand heavy SPG debuted alongside it. The USSR, USA, and Great Britain had to catch up. Only Soviet tank builders ended up producing a worthy opponent with the IS-2 and ISU-152. The Tiger Ausf.B was supposed to be Germany's answer, but it never reached the status of "king of beasts" like the Tiger did. Its influence on Soviet tank building was also far lesser.

I report on the results of trials of tank #4 and its condition as of September 3rd, 1948.

On August 31st, 1948, after driving trials on a cobblestone highway, intensive leakage of oil from the engine block pressure plug due to gas penetration was discovered. When the engine was disassembled at the factory, the following was found: destruction of the piston and rings, deformation of the sixth left hand cylinder, high wear on the rings of the other pistons.

The destruction of the piston and rings took place due to working the engine at high head during trials that was permitted to occur by the cooling system in normal conditions and the general unrefined nature of the M-50T piston group. 

In total tank #4 travelled for 1400 km between July 25th and August 31st, 1948. The engine worked for 84 hours 30 minutes, 16 hours 40 minutes of those without load.

Just Add Armour

 The caleidoscope of various vehicles based on the Heavy Tank T26E3 shows how difficult the situation was with American heavy tanks. The T26E3 was really a medium tank, especially when it came to armour. Several variants were developed to make it into a true heavy, from installing more powerful armament to a thorough modernization that resulted in the Heavy Tank T32. The simplest variant was the Heavy Tank T26E5 where the designers decided to limit themselves to thickening the tank's armour.

The British Way: Boys and PIAT

In WWI the British created a new type of armoured vehicle: the tank. Very little attention was dedicated to the issue of anti-tank defense, as the Germans had very few analogous vehicles. However, in the interbellum period it became clear that the British infantry will have to face an enemy with a large amount of tanks, and so the issue had to be resolved.

PIAT Review

A limited number of PIAT anti-tank grenade launchers were shipped to the USSR in 1944, but it was unclear if any of the weapons ever made it to the front line. Turns out they have, although they name they were given by Soviet troops makes tracing their path difficult. However, these weapons were found in one unit: the 252nd Independent Special Purpose Motorized Battalion. On December 2nd, 1944, the battalion reports 18 "rocket powered guns" in its possession. The battalion fought from August of 1944 to to May 9th 1945 and had little good to say about its weapons.

Big Anti-Tank Feline

 The Jagdpanther is one of the most famous German tank destroyers of WW2. Even though it was built on the chassis of the medium Panther tank, it's classified as a heavy tank destroyer. Many consider it the best German tank destroyer. The Jagdpanther combined good mobility, high protection, a powerful gun, and it had defensive armament, which is important for a tank destroyer. However, its influence is often overestimated. The vehicle was only available in large numbers by late 1944 and arrived on the Eastern Front only in January of 1945. The way these tank destroyers were used was often different from the original intention and this impacted its usefulness. Finally, the vehicle was far from the most reliable.

Tank Brigade Experience

"To Deputy People's Commissar of Defense, Lieutenant General Fedorenko

Experience in battle, especially the experience of the [91st Tank] Brigade between August 21st and 29th, 1942, shows that the KV tank lost its advantage over the T-34 in protection, as the same caliber of gun can penetrate both the KV and T-34. The KV has a significantly different weight and dimensions than the T-34, is less maneuverable, and is thus inferior to the T-34.

Bug with a Big Caliber

Germany was a leader in self propelled artillery at the start of WWII. Approaching the idea of motorized artillery from a new angle, they ended up with a wide spectrum of SPGs by the middle of the war. This also applied to self propelled howitzers, which were first used in France in 1940. Truly mass produced SPHes entered service closer to mid-1943. These were the Grille (Grasshopper), the best SPG series with the 149 mm sIG 33 howitzer.
