The Denel GT-3 cannon is an South African cannon developed in their efforts to upgrade existing Centurion with a more powerful cannon. Due to international embargo imposed on the South African state, the South African government must outsource their parts elsewhere.

This cannon uses a modified 105mm barrel while retaining the original [[20pdr OQF Mk.I (84 mm)]] gun breech from their Centurions. The resulting gun could fire NATO compatible ammunitions.

The Denel GT-3 cannon has a very similar performance to the powerful [[L7A3 (105 mm)]] cannon found on most Leopards and the Japanese Type 74s. More specifically, it has access to all ammunitions found in the [[Leopard 1A5]] with the same characteristics, plus an M416 smoke round and the DM63 for the [[TTD]].

This page is about the South African GT-3 (105 mm) cannon. For variants, see L7 (105 mm) (Family).

Description

The Denel GT-3 cannon is an South African cannon developed in their efforts to upgrade existing Centurion with a more powerful cannon. Due to international embargo imposed on the South African state, the South African government must outsource their parts elsewhere.

This cannon uses a modified 105mm barrel while retaining the original 20pdr OQF Mk.I (84 mm) gun breech from their Centurions. The resulting gun could fire NATO compatible ammunitions.

General info

The Denel GT-3 cannon has a very similar performance to the powerful L7A3 (105 mm) cannon found on most Leopards and the Japanese Type 74s. More specifically, it has access to all ammunitions found in the Leopard 1A5 with the same characteristics, plus an M416 smoke round and the DM63 for the TTD.

Available ammunition

Basically, most of the South African shells are literal copies of German shells. Every single shell has the same exact characteristics and their German counterparts. Here are the shell types available for the Denel GT-3. The shells listed in brackets are their original German shells that the South African shells are based upon.

A really important note. The M152, M156 and M111 shells are available to all tanks using the Denel GT-3 cannon. The M416 smoke round is available only for the Olifant Mk.1A, the DM33 is present only in the Class 3 (P), while the DM63 is used only in the TTD.

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.

Pros:

Cons:

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.
