"To the Chief of the Rear and Supply Directorate of the General Staff, Major General comrade Yermolin
According to your order, I present to you the conclusions on the draft project of a tank glider developed by TsAGI engineers including comrade Yermonskiy.
The project proposes a 6 ton tank that can be towed behind an airplane as a glider. The tank accelerates on its tracks with the tank's engine power to at least 100 kph.
The proposal has the following issues:
- No tank presently exists that weighs 6 tons and can reach a speed of 100 kph.
- The creation of a tank weighing 6 tons with armament and armour that meets modern requirements is a big issue.
Because of this, the realization of this project would not be sensible.
In addition, I report that factory #81 is working on air transport of military materiel, including a T-40 tank, using high capacity cargo aircraft. All necessary information about the vehicles and armour was sent to the GABTU.
I consider the work performed by factory #81 to be more reasonable and capable of replacing this proposal.
