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.

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.
