HELSINKI/WASHINGTON—Finland signed a $9.4 billion agreement on Friday to buy U.S. F-35 fighter jets, reaching a deal to bring 64 radar-evading warplanes to a country bordering Russia at a time of high tensions between Moscow and the West over Russian troops massed near the Ukrainian border.
However it will be some years before the planes enter service. Finland has previously said the planes would begin to be deployed in 2027.
