General Dynamics [GD] on Wednesday said its Mission Systems-Canada business received four contracts worth a combined $1.3 billion to support the Canadian army.

The work supports the army’s Land C4ISR System and cover system of systems engineering and integration, core network sustainment services, applications sustainment services, and intelligence, surveillance, target acquisition, and reconnaissance (ISTAR).

GD said the systems engineering and integration contract covers architecture and design of Land C4ISR and integration of all the systems’ capabilities. GD will also provide an advanced facility and vehicle bay for the armed forces to support ongoing Land C4ISR work.

The network sustainment services contract covers the Land C4ISR core network and “delivers the digital backbone of the Land C4ISR capability, including the soldier domain, mobile domain, and headquarters domain,” GD said. The application services contract supports all user-facing services and software that leverage the mobile and headquarters domains.

The ISTAR project will help the army manage and distribute ISR data from soldiers and sensors across the land, airborne, and naval domains, GD said.

“Over three decades ago, we were awarded a contract to create the first fully integrated voice and data network in the world, this was the beginning of the digitization of the Canadian army,” Andrew Shepard, vice president land and joint solutions for GD Mission Systems-Canada, said in a statement. “Today we are looking forward to furthering our collaborative partnership with Canada in order to meet the forward operational needs of the Canadian Armed Forces.”
