The Loggim program or TTD Program was project to develop a new Main Battle Tank for the South African Defence Force (SADF) during the 1980s. It was initiated after the SADF recognized from combat experience in South West Africa (Now Namibia) and Angola during the SADF Border war that its Olifant MBTs were increasingly unsuitable to counter the Soviet-designed tanks that were being deployed in southern Africa.[1] The project was cancelled in the early 1990s, before any new tanks were delivered for trials or operational purposes.
History
The Loggim Program or (TTD Program) started from the early 1980s and was started because the SADF recognized from their combat experience in South West Africa (Now Namibia) and from their experience in Angola during the SADF border war that they need a New Main Battle Tank (MBT) to counter the rising threat of soviet MBT's and that they need to replace their old Olifant MBT's.
The project was called "Loggim" and involved Reumech Olifant Manufacturing Company (OMC) building the hull, while Lyttleton Engineering Works (LEW) designed the turret.[2][3]
The project was developed from roughly 1983, with the prototype (TTD) completed around 1992.[citation needed] The prototype was developed in the early 1990s by ARMSCOR (later Denel) and ReuMech Olifant Manufacturing Company. It resembled the Leopard 2 in profile because of the use of compound armour. It weighed 58 tonnes (64 tons) and was driven by a 1,250 horsepower (930 kW) diesel engine. The prototype was equipped with a 105 millimetres (4.1 in) main gun but the production units were planned to have a 120 millimetres (4.7 in) gun.[4]
The program was cut in the early 1990s following the end of the South African Border War and changes in the political climate.[citation needed]
Variants
The TTD had 3 Variants 2 of which were just proposed.[5]
Prototype Variant: The prototype variant used a 105mm GT3 QF Cannon[6] and didn't have a machine gun or ERA, it had 2nd generation Thermal Vision Devices (TVD) and Night Vision Devices (NVD).
Production Variant: The Production Variant was planned to use the 120mm GT6 QF main cannon,[7] it had ERA and a 7.62mm Machine Gun.
Upgradable Variant: The Upgradable Variant was planned to use a 140mm QF main cannon, it was probably going to use ERA and a 7.62mm Machine Gun Aswell but it's not confirmed.
