April 21 (UPI) — The U.S. State Department has approved the possible foreign military sale of C-17 Globemaster III sustainment to the government of Canada.

If approved by Congress, Canada will receive follow-on support for five C-17 aircraft, natively designated as CC177s. Tasks will include in-country field services, maintenance and technical support, spares and additional equipment.

According to the U.S. Defense Security Cooperation Agency, the program is expected to cost $195 million. The agency adds the proposed sale will advance U.S. foreign policy interests by strengthening military airlift capabilities for a close ally and NATO partner.

Boeing, the company that manufactures the C-17, has been selected as the primary contractor with additional support from Lockheed Martin.

The C-17 Globemaster III aircraft is a four-engine military transport plane used to carry troops and equipment. Additional users include Australia, India, Kuwait, Qatar, Britain and the United Arab Emirates.
