A second stage of trials for Object 701 prototype #1 began #OTD in 1944. Reliability issues with this iteration of the design meant that prototype #2 was submitted for government trials later that year. #tanks#history#WW2#WWII
Discussions of where to mount the OBM-51 high power 122 mm gun began #OTD in 1943. The gun was originally intended to go into a new turret on the KV-1S chassis, but high power 122 and 152 mm guns were only installed in fixed casemates. #tanks#history#WW2#WWII
The ersatz Panzer IV/70(A) was put into production to make up for shortages of the Panzer IV/70(V). Not enough of these were built either, as Nibelungenwerk was bombed #OTD in 1944 and rates of production cratered. #tanks#history#WW2#WWII
Production of the first 10 SG-122s was due #OTD in 1942, with 10 more expected every two weeks. Unfortunately, production was limited by the number of captured StuG and Pz.Kpfw.III chassis, and so only 21 units were ever produced. #tanks#History#WW2#WWII
The 67th Infantry Regiment (Medium Tanks) was formed #OTD in 1932. F company of this regiment was composed of three Christie tanks. These tanks served the infantry well, although convertible drive tanks never became common in the US Army. #tanks#history
A model of factory #8's ZIK-20 was due #OTD in 1942. The idea of putting a 152 mm gun on the KV chassis in a casemate rather than a turret was a good one, but by the time the project was reviewed it was clear that ChKZ's SU-152 was a better implementation. #tanks#history#WW2
The EKV (KV-1S tank with an electric transmission) was due for trials #OTD in 1943. This tank did not go into mass production but served as a starting point for the development of the IS-6 tank. #tanks#history#WW2#WWII
The Skink arrived at Lulworth #OTD in 1944 for trials. The Canadian AA tank was reviewed very positively and even ferried over to Europe for a brief battlefield trial before VE Day. #tanks#history#WW2#WWII
#OTD in 1944 mobility trials of the King Tiger tank ended abruptly. After driving just 113 km in Soviet hands (and 557 km in total), catastrophic failure of the left side drive sprocket and front torsion bar disabled the tank for good. #tanks#history#WW2#WWII
#OTD in 1925 the Red Army discussed buying Vickers medium tanks. 15 Medium Tanks Mk.II were only purchased in 1930. They ended up being of little use, eventually sent to be installed as static machine gun emplacements, stripped of their engines and armament. #tanks#history
#OTD in 1942 Churchill III tanks went into action at El Alamein. Unlike the botched Dieppe raid earlier that year, they were able to make good use out of their powerful weapons and thick armour against German tanks. #tanks#history#WW2#WWII
The KV-9 prototype tank armed with a 122 mm U-11 howitzer was built in early 1942. It was never mass produced. #OTD in 1942 production of a pilot batch on the lightened KV-1S chassis was authorized, but it was never built. #tanks#history#WW2#WWII
Soviet development of night vision prioritized tank drivers. #OTD in 1942 after an experimental batch of devices for drivers was deployed, an order was given to develop night sights for gunners. This work was not finished by the end of the war. #tanks#history#WW2#WWII
Requirements for the T-43 tank were issued #OTD in 1942. Morozov, the tank's lead designer, fought against the army and the government on this, pushing through his own vision of the tank. He got his way, but the resulting tank proved unsatisfactory. #tanks#history#WW2#WWII
Disarmament talks in the early 1930s could have potentially set a weight limit of 16 tons for all new tanks, and many new designs adhered to this limit. #OTD in 1933 Germany left the conference, kicking off another arms race as the looming weight limit disappeared #tanks#history
The ISU-152 prototype finished gunnery trials #OTD in 1943. There were some minor faults with the vehicle, but they were either correctable or already shown to be tolerable on the vehicle's precursor, the SU-152. #tanks#history#WW2#WWII
Prospective SPAAGs arrived at the Kubinka proving grounds #OTD in 1942. Even though the T-90 gave the best results, testers preferred the idea of adapting the T-90 turret to the T-60 chassis to use up leftover hulls. #tanks#history#WW2#WWII
#OTD in 1942 factory #592 was ordered to build the SG-2 SPG. It was a better design than UZTM's U-35, but the defective chassis given to the factory to built their prototype doomed the project and the U-35 was chosen to become the SU-122 instead. #tanks#history#WW2#WWII
The Sherman tank made its debut #OTD in 1942 as a part of the Second Battle of El Alamein. The tank was very well received, as its thick sloped armour and powerful gun outmatched any German tank on the battlefield at the time. #tanks#history#WW2#WWII
The Heavy Tank T1 was built with a coaxial 37 mm gun in addition to its main 76 mm gun. The decision to replace it with a .30 cal machine gun was made #OTD in 1942, but the replacement was never made. #tanks#history#WW2#WWII
