New Canadian Prime Minister Mark Carney has asked his defense minister to review the purchase of America’s F-35 fighter jet to see if there are other options “given the changing environment," a spokesman for the minister said Saturday.

Portugal could replace its ageing American-made F-16 fighter jets with European jets rather than F-35s following U.S. President Donald Trump's policy shifts, the country's defence ministry said on Friday.

Canada's deal with Lockheed Martin and the United States government is for 88 F-35 fighter planes at a cost of about US$85 million each.

Portugal said it was reconsidering purchasing the Lockheed Martin-made F-35 jet in the wake of Trump's recent policy shifts.

Canada’s new Prime Minister Mark Carney ordered a review of the country’s contract with the US’s Lockheed Martin Corp for F-35 fighter jets, a new front in the dispute between the two sides in response to tariffs and expansionist rhetoric from President Donald Trump.
