BIG blow to US as NATO countries preparing to refuse to buy F-35 due to…
NATO countries are reconsidering their commitment to buy F-35 fighter jets following US President Donald Trump’s continued tariff threats and his stance on the Russia-Ukraine war. Currently, the F-35 is operated by 19 allies of the US, including non-NATO countries such as South Korea, Japan, Australia and Israel. Many NATO members had planned to buy F-35 aircraft to replace their aging fleets.
These countries were trying to replace their older American, European and even Soviet-era fighter jets by buying the American F-35. But, recent geopolitical developments have put these deals under scrutiny. On Thursday, Portugal’s defense minister pointed to “recent US positions in the context of NATO” as a reason for re-evaluating plans to replace 28 F-16s with the F-35 Lightning II.
Canada orders review
Similarly, Canada’s newly appointed Prime Minister Mark Carney has also ordered a review of his country’s $13 billion contract for 88 F-35s. Uncertainty also remains over Germany’s order for 35 aircraft. The F-35 program has suffered from constant cost overruns and technical setbacks. Despite this, it remains one of the world’s most advanced fighter aircraft, with stealth capabilities, state-of-the-art sensors and multi-role functionality.
NATO members benefit from operating the same aircraft because it simplifies pilot training, maintenance, spare parts supply and munitions compatibility.
What’s the alternative
For countries seeking alternatives, Sweden’s Saab JAS-39 Gripen is emerging as a potential choice. Despite being less stealthy, the Gripen has greater speed, range and significantly lower procurement and operating costs.
