Questions are mounting in Canada and in Europe over whether big-ticket purchases of high-end U.S. weaponry, such as the F-35 Joint Strike Fighter, are still a wise strategic choice for Western countries worried about their investment in U.S. defense technology. In less than two months, U.S. President Donald Trump has upended decades of foreign policy. He has left NATO members questioning whether Washington will honor the trans-Atlantic alliance’s commitment to defend each other, if other European countries are attacked by Russia. He’s also made repeat overtures to Moscow and suspended most U.S. foreign aid. That could impact foreign sales of the Lockheed Martin-produced F-35 and other advanced U.S. jets like the F-16. As Russia’s war in Ukraine grinds on, it’s become clear that Eastern European NATO members still have vast stores of Soviet-era weapons in their stockpiles that weren’t interoperable with Western weaponry. A long-term plan to get all of NATO on similar platforms — by replacing old Soviet-era jets with Western ones, particularly the F-16 and in some cases, the F-35 — has gained momentum. Some of the NATO countries are now rethinking tying their defense to U.S.-made systems and potentially considering European jets. And the European Union on Wednesday announced a new drive to break its security dependency on the United States, with a focus on buying more defense equipment in Europe. In recent years, the EU’s 27 nations have placed about two-thirds of their orders with U.S. defense companies. Angering an F-35 partner In Canada, where Trump has launched a trade war and has threatened economic coercion to make it the 51st American state, new Prime Minister Mark Carney has asked Defense Minister Bill Blair to review its purchase of F-35s. Canada has been a partner with the U.S. in developing the fighter. Blair will see if there are other options “given the changing environment,” a defense spokesman said. Carney on Tuesday announced an early warning radar system purchase from Australia worth Canadian $6 billion ($4.2 billion). Officials say it will have a smaller footprint than a similar American system. And in Portugal, the outgoing defense minister recently told a Portuguese newspaper that “recent positions” taken by Washington compelled a rethink about the purchase of F-35s. Portugal is considering various options to replace its F-16s. “You’re not just buying an airplane, you’re buying a relationship with the United States,” said Winslow T. Wheeler, who spent three decades in U.S. Congress working for Democrats and Republicans on national security and defense issues. “People in the past have not just welcomed, but craved that kind of relationship.” The Netherlands and Norway, on the other hand, have recently voiced support for the F-35 program. The F-35 and a ‘kill switch’ The F-35 Joint Strike Fighter was designed to combine stealth, maneuverability and attack capabilities in a single aircraft. Each jet costs about $85 million (78 million euros), and the price jumps to as high as $150 million (137 million euros) when supporting infrastructure and spare parts are included. About 1,100 have been produced to date for 16 military services across the globe. The F-35B, a variant that can take off from ship decks vertically, is the latest model. It’s the most expensive weapons system the U.S. has ever produced, with estimated lifetime costs now expected to top $1.7 trillion. One […]
