The live fire tests were conducted in the fall of 1944 at Kubinka, during the course of which the following results were obtained:
«1. The quality of armor on the „Tiger-B‛ tank, in comparison with the armor on the „Tiger-I,‛ and „Panther,‛ tanks, as well as early production „Ferdinand‛ self-propelled gun, has sharply deteriorated. The first individual impacts caused cracks and spalling in the armor of the „Tiger-B‛ tank. Groups of shell impacts (3–4 shells) caused large-scale spalling and fractures in the armor.
2. Weak weld seams appeared characteristic of all hull and turret joints. Despite careful workmanship, the seams held up to shell impacts significantly worse than they did in analogous constructions on the „Tiger-I,‛ and „Panther,‛ tanks, as well as the „Ferdinand‛ self-propelled gun.
3. Impacts of 3–4 armor-piercing or high-explosive fragmentation shells from 152, 122, or 100 mm artillery pieces caused cracks, spalling and destruction of the weld seams in the tank's 100–190 mm thick frontal armor plates at ranges of 500–1000 metres. The impacts disrupted the operation of the transmission and took the tank out of service as an irrevocable loss.
4. Armor-piercing projectiles from the BS-3 (100 mm) and A-19 (122 mm) gun completely penetrated when impacting the edges or joints of the „Tiger-B‛ tank's front hull plates at ranges of 500–600 metres.
5. Armor-piercing projectiles from the BS-3 (100 mm) and A-19 (122 mm) gun completely penetrated the „Tiger-B‛ tank's front turret plate at ranges of 1000–1500 metres.
6. 85 mm armor-piercing projectiles from the D-5 and S-53 gun failed to penetrate the tank's front hull plates or cause any structural damage at distances of 300 metres.
7. The tank's side armor 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.
8. The tank's hull and turret side plates were penetrated by armor-piercing projectiles from the domestic 85 mm and American 76 mm guns at ranges of 800–2000 metres.
9. The tank's hull and turret side plates were not penetrated by armor-piercing projectiles from the domestic 76 mm guns (ZJS-3 and F-34).
10. American 76 mm armor-piercing projectiles penetrated the „Tiger-B‛ tank's side plates at ranges 1.5 to 2 times greater the domestic 85 mm armor-piercing projectiles.»
