The Globe and Mail reports in its Friday edition that Ottawa will spend $10.4-billion on a new fleet of Boeing maritime patrol aircraft, a sole-source purchase that will replace Canada's aging surveillance planes amid rising threats in the Arctic and elsewhere. The Globe's Eric Atkins writes that Canadian officials on Thursday said they have signed an agreement with the U.S. government for 14 Boeing P-8A Poseidon aircraft, with an option for two more. The first deliveries are expected in 2026 with the final planes arriving about a year later, Defence Minister Bill Blair said at a news conference in Ottawa. The Boeing Poseidon, based on the 737, is used by eight of Canada's allies, including the United States, Britain, Australia and New Zealand. It has advanced weapons and sensor systems with antisubmarine and surface-combat capabilities. Mr. Blair told reporters the Boeing Co. aircraft will ensure Canada's military is able to exceed the threats posed by China, Russia and others while upholding the military's commitment to Canadians. The fleet will be based in Greenwood, N.S., and Comox, B.C. Poseidon's Canadian suppliers include GE Aviation Canada and CAE. The aircraft will be assembled in Kansas and Washington State.
