The final report of 16 February 1945 on the "Tiger-B" tests, stated the following:

"The frontal hull and turret armor is low quality. Non-penetrating damage (dents) in the armor caused cracking through the armor and large scale interior spalling. The side plates were notable for their sharply unequal durability in comparison with the frontal plates and appeared to be the most vulnerable part of the tank's hull and turret.

Shortcomings:
The chassis is complex and is not durable.
The steering mechanism is complex and expensive.
The side running gear is extremely unreliable.
The radius of action is 25% inferior to the "IS"-tanks.
The ammunition (except in the turret recess) is awkwardly located.
The excessive size and weight of the tank do not correspond to the tank's armor protection and firepower."
