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.
