defenceWeb Written by Guy Martin - The Chaka command and control system. Global Command & Control Technologies (GC2T) is one of the newest defence companies to emerge in South Africa, specialising in command, control, training and simulation solutions. GC2T emerged from Saab Grintek Defence after the latter divested some of its portfolios, which were then taken over by GC2T. Saab first announced the divestment in March 2019, saying that around 50 Saab employees would be affected, leaving 730 staff at Saabâs facilities in Centurion and Cape Town, focussing on the development and production of mainly electronic warfare and avionics systems for the global market.
