Flygsystem 2020

The Flygsystem 2020 ("Flight System 2020", abbreviated FS 2020) is an ongoing project by the Swedish Air Force to develop a fifth-generation low-observable fighter jet by 2035. Little public information exists about the project; there are no official statements about the current stage of development, although a video claims to show a miniature prototype test. In 2012, Lieutenant Colonel Lars Helmrich of the Swedish Air Force asked members of the Riksdag to consider the development of a new jet fighter or to upgrade all present JAS 39 multirole fighters to the NG model, claiming the early versions of the aircraft will be obsolete by 2020.

The Saab/Linköping University Generic Future Fighter project  is a testbed for its technologies.

Partnership
During a state visit of the President of Turkey to Sweden on 13 March 2013, Türk Havacılık ve Uzay Sanayii AŞ (Turkish Aerospace Industries, TAI) signed an agreement with Sweden's Saab to provide design support services to Turkey for the TAI TFX program.

However, the collaboration with Turkey was under pressure due to Turkey being removed from the Joint Strike Fighter program. To tackle this, in July 2019 the Swedish government signed a memorandum of understanding with the United Kingdom to jointly develop technologies for the British BAE Systems Tempest sixth-generation stealth fighter program; these technologies may be integrated to Sweden's own Flygsystem 2020 project. This was extended to include Italy in December 2020.

On 9 December 2022, the UK, Japan and Italy merged their sixth-generation fighter jet projects, creating the Global Combat Air Programme (GCAP). Japan and Sweden signed an agreement on possible future cooperation in the GCAP program in late December.
