I started construction with the chassis tub. First thing to do is gluing the back wall. Next I cut the suspension arms out of the casting block and it turned out the holes for their pins are much too small. Off with the pins, arms are drilled through, as is the tub itself – naturally observing the locations of the original holes.
I decided to use thick copper wire passing through the whole tub to make new pins. This would ease me in terms of affixing the pins and make the whole thing stronger.
The AT-T (Russian “Artilleriyskiy Tyagach – Tyazholiy”, Artillery Tractor – Heavy) was developed in the late 1940s using elements of the T-54 MBT (notably the running gear).
The main purpose of the vehicle was to tow heavy artillery pieces like the KS-30 130mm AA gun, the S-23 180mm gun and the B-4 203mm howitzer, so the machine got a 415HP version of the famous B-2 V-12 tank diesel. The standard 5-roadwheel chassis was used for a number of recovery and engineering vehicles. Extended versions (7 roadwheels) include the P-40 „Long Track” mobile radar, and an entire family of polar expedition vehicles.
