SAAB were contracted some years ago to do a pre-feasibility study. In late 2015 SAAB, Airbus and BAEs were invited to tender for the 4 year preliminary design phase for a 5th generation LO air superiority platform (think F-22). It's likely to be a twin-engined aircraft, possibly with new co-developed engines; R-R UK have proposed a $500m co-development programme. About a year ago BAEs was selected for pre-contract negotiations; a contract was very close to being signed at Farnborough, but the Programme Directory, a Maj Gen Aksoy, was arrested on his return to Turkey, immediately following the coup attempt. Airbus tried to get another deal on the table last year but the Turks were happy to partner with the UK - as this proposal has massive cross-Government support. SAAB have now no involvement in the programme. Oh, and the contract is worth about $160M.
But the bottom line is that the Turkish Government want something that is exportable and have an eye on the global F-16 fleet. Should the PDC go well (and BAEs is heavily resourcing it), it's likely they will be kept on and there will be many other UK companies involved - along with the burgeoning hi-tech Turkish defence industry (much of it quasi-state-owned). I think we will see the RAF working closer with the TurAF on collaboration programmes, as they struggle to rebuild after the coup attempt (perhaps 30% of F-16 pilots were dismissed and/or arrested; including almost all of their FJ QFIs...apparently).
Outside of FCAS, this is the only forward looking programme on the BAEs books with real potential to produce the next generation of aerospace engineers.
