The US State Department has approved a Foreign Military Sale (FMS) to Turkey covering 40 new F-16 Block 70s and the modernisation of 79 existing F-16s to F-16V standard, the US Defense Security Co-operation Agency (DSCA) announced on 26 January.

The deal, which is worth USD 23 billion (EUR 21.24 billion), has been passed to the US Congress for final approval.

Turkey had first requested the jets in 2021, but its previous failure to ratify Sweden’s bid to enter NATO had held up any sale, although the US State Department did approve a USD 256 million upgrade package for Turkey’s F-16C/Ds in April 2023.

However, Turkey reversed its decision on 25 January 2024, when the Turkish parliament endorsed Sweden’s NATO accession, and Turkish President Tayyip Erdoğan subsequently also endorsed the move.

The Turkish Air Force is having to operate its F-16s for much longer than it originally expected. Having joined the Lockheed Martin-led F-35 Joint Strike Fighter (JSF) programme in July 2002, initially intending to order 116 F-35As to replace its F-16 fleet, Turkey was ejected from the programme on 17 July 2019 after the government of President Erdoğan refused to cancel a programme to procure the Russian S-400 air defence system that would have compromised the F-35’s stealth characteristics.

Meanwhile, in August 2016 Turkish Aerospace received a design and development contract from the then Turkish Undersecretariat for Defence Industries for a twin-engined indigenous replacement for the F-16 under the TF-X programme. This aircraft, which was officially rolled out on 18 March 2023, was given the name ‘Kaan’ on 1 May 2023. The aircraft was scheduled to make its first flight on 27 December, but the maiden flight was postponed. The Kaan’s entry into service thus remains some years away.
