Description
The Denel GT-3 cannon is an South African cannon developed in their efforts to upgrade existing Centurions with a more powerful cannon. Due to international embargoes imposed on South Africa, the South African government had to outsource their parts elsewhere.
This cannon uses a modified 105 mm barrel while retaining the original 20pdr OQF Mk.I (84 mm) gun breech from their Centurions. The resulting gun could fire NATO compatible ammunitions.
Vehicles equipped with this weapon
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. Thus, in War Thunder, the Denel GT-3 cannon is more akin to the Argentinian FMK.4 Modelo 1L (105 mm) in every aspect. For example, the Olifant Mk.1A has every rounds available to the TAM except for its APDS round. The TTD, on the other hand, has all ammunition available for TAM 2C. Finally, the Class 3 (P) fires every round available for the TAM 2IP.
Available ammunition
|
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.

History
The Denel GT-3 was a South African cannon developed by Denel Land System DLS in their effort to upgrade existing Centurion tanks with a 105mm cannon. Due to international sanctions forbidding South Africa to acquire new weapons, their aging tank force and experiences in the Border War against Angola, the South Africans resorted to making their own weapons with whatever if available to them, including their Centurion Mk3s and their 84mm cannon. It was decided to use the Centurion as a basis for a new indigenous South African tank (as they have no other options available).
The resulting product was a 105mm cannon. This cannon, known as the 105mm Denel GT-3, retains the 84mm's breech assembly, while fitting it with new mounting lugs to fit existing recoil system. The barrel is a similar copy to the original British L7A3's own barrel, with a couple of minute changes to fit in with the different breech assembly. The resulting cannon could fire NATO ammunition.
The Denel GT-3, with the Israeli supplied M111 APFSDS round could penetrate a T-54/55 and T-62 up to a range of 2km. However, most Olifant Mk1A crews preferred HEAT-FS rounds due to it making a much more noticeable impact, considering that the Olifant Mk1A faces Angolan T-54/55 and T-62s that does not have any form of composite or reactive armour.
On Novermber 1987, as part of Operation Moduler, Lt. Hein Fourie destroyed the first T-55 with an Olifant Mk1A armed with the Denel GT-3 cannon. Overall, the Denel GT-3 cannon was successful in its role in modernising the South African army with a tank cannon that is capable of dominating the African battlefield without outside assistance.
Apart from the Olifant, the Denel GT-3 would also be installed in the Tank Technology Demonstrator (TTD) as a placeholder while a 120mm was being developed, which unfortunately was scrapped.
Media
Excellent additions to the article would be video guides, screenshots from the game, and photos.
