Description
The 155 mm 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 105 mm T5E1 gun on the T29 Heavy Tank. It had a low velocity of only 701 m/s (2,300 ft/s) compared to the 120 mm T53 on the T34 Heavy Tank (945 m/s) and the 105 mm 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.

General info
The 155 mm gun T7 is 6.74 m (22.1 ft) long cannon unique to the T30 Heavy Tank. It has a distinctive muzzle brake 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.
Available ammunition
Describe the shells that are available for the weapon and their features and purpose. If it concerns autocannons or machine guns, write about different ammo belts and what is inside (which types of shells).
Comparison with analogues
Give a comparative description of cannons/machine guns that have firepower equal to this weapon.
Usage in battles
Describe the cannon/machine gun in the game - its distinctive features, tactics of usage against notable opponents. Please don't write a "guide" - do not impose a single point of view, but give the reader food for thought.
Pros and cons
Pros:
- The 155 mm HE round is capable of knocking out most tanks in the game
- Both types of AP rounds are almost guaranteed to result in a kill if they penetrate a tank's armour
Cons:
- Shells have less explosive filler than slightly smaller German HE rounds
- 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)
History
Examine the history of the creation and combat usage of the weapon in more detail than in the introduction. If the historical reference turns out to be too long, take it to a separate article, taking a link to the article about the weapon and adding a block "/History" (example: https://wiki.warthunder.com/(Weapon-name)/History) and add a link to it here using the main template. Be sure to reference text and sources by using <ref></ref>, as well as adding them at the end of the article with <references />.
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
