T7 (155 mm)

Description

The 155mm L/40 T7 was an American rifled tank gun developed in 1945. The T7 was to be the main armament for the T30 Heavy Tank, but only a handful were produced due to the T30 project being cancelled after trials in the late 1940s.

The T7 used two-part separated ammunition like the 105mm T5E1 gun on the T29 Heavy Tank. It had a low velocity of only 701 m/s (2,300 ft/s) compared to the 120mm T53 on the T34 Heavy Tank (945 m/s) and the 105mm T5E1 on the T29 Heavy Tank (945 m/s). However, the 43 kg (95 lbs) High-Explosive shell was demonstrated to have a powerful demolition effect.

Comparison with analogues

Give a comparative description of cannons/machine guns, that have firepower equal to these type of weapons.

Usage in battles

The 155 mm gun T7 is 6.74 m (22.1 ft) long cannon unique to the T30 Heavy Tank, a U.S. premium tank at 6.7 BR. It has a distinctive muzzle break which allows it to be distinguished from similar tanks using the T5E1 or T53 cannon such as the T-29 and T-34. It is slightly shorter than both cannons.

Pros and cons

Summarize and briefly evaluate the weaponry in terms of its characteristics and combat effectiveness. Mark pros and cons as a list.

Pros:

• The 155mm HE round is capable of killing most tanks in the game
• Both types of AP rounds are almost guaranteed to result in a kill if they penetrate a tank's armor

Cons:

• Shells travels at significantly slower velocity than the T5E1 and T53 guns mounted on the T29 or T34. (roughly 700 m/s compared to over 900 m/s)
