Description

Write an introduction to the article in 2-3 small paragraphs. Briefly tell us about the history of the development and combat using the weaponry and also about its features. Compile a list of air, ground, or naval vehicles that feature this weapon system in the game.

Vehicles equipped with this weapon

General info

The L7A3 shares many of its properties with the L7A1 on British tanks, although it has access to a wider range of ammunition. Aside from the standard APDS and HESH rounds, the L7A3 is found to use HEATFS as well as a smoke shell. The L7A3 can be found either unstabilized or fully stabilized depending on the vehicle. Giving accurate fire at long ranges that can punch through even heavily armoured vehicles, the L7A3 is a highly capable weapon for the vehicles it is found on and will often face.

Comparison with analogues

  • L7A1 (105 mm): The L7A1 is the British original version of the L7A3, and has identical performance with the exception that no HEATFS shell is available for the L7A1.
  • M68 (105 mm): The M68 is the American production version of the L7, and so also shares identical performance for matching shells, although the Americans have added a smoke shell in the place of having smoke grenades on vehicles.
  • D-10T2S (100 mm): Unlike the standard D-10T found on the T-54, the D-10T2S uses a full stabilizer and has access to ammunition such as the 3BM25 which performs similarly to DM23 and M735 on the L7A3. However, the vehicles using the L7A3 reload faster than the T-55A (which uses the D-10T2S), although the T-55AM-1 does have a gun-launched ATGM which is not a feature found on the L7A3.
  • OTO Melara 105/52 (105 mm): The OTO Melara 105/52 shares ammunition with the L7A3, and Italian vehicles using it such as the Centauro and OF-40 can reload as fast as the German and Japanese vehicles with the L7A3.
  • CN-105-F1 (105 mm): The CN-105-F1 has drastically limited ammunition available with only a single shell of each major type present, but the ammunition is just as good or better than that found on the L7A3 as the OFL 105 F1 has the edge in penetration over DM23, although the Japanese Type 93 is still the top ammunition choice.

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

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

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

An excellent addition to the article would be a video guide, as well as screenshots from the game and photos.
