The State Department has approved a possible $195 million Foreign Military Sales request to Canada sustainment support for C-17 aircraft.

The Defense Security Cooperation Agency (DSCA) notified Congress of the potential sale on April 19.

The request includes the possible sale of follow-on support for its five CC177 aircraft (Canada’s designator for the C-17), including contractor logistics support provided through the Globemaster III Integrated Sustainment Program, in-country field services support, aircraft maintenance and technical support, support equipment, and alternate mission equipment.

It also includes software support, spares, personnel training and training equipment, U.S. government and contractor engineering and logistics support services, publications and technical documentation, and major modification and retrofit kits support.

The primary contractors include Boeing [BA] and its training systems business unit as well as Lockheed Martin [LMT].

The agency said that sources of supply will award contracts when necessary to provide defense articles ordered if the items ordered are not available from U.S. stock or are considered lead-time away.

Canada will use this support to ensure its continued capability to rapidly deploy its forces as well as continued interoperability with between U.S. and Canadian C-17s.

DSCA highlighted this sale “is required to maintain the operational readiness of the Royal Canadian Air Force C-17 aircraft” and that Canada’s current contract supporting its five C-17s will expire on Sept. 20.

Implementation of the sale will not require the additional assignment of any U.S. government or contractor representatives to Canada because there is an on-going FMS case providing C-17 sustainment services with 13 contractors from Boeing in-country to provide technical support services on a continuing basis.
