He added: “A domestic order will not only fulfil a military requirement for the RAF in these unstable times but will also ensure that vital skills required to build the next-generation aircraft, are retained at Warton.
“Without a domestic order for Typhoon there will be no GCAP due to the loss of the skills necessary to build and fly aircraft.
“Furthermore we feel a domestic order will give other nations considering buying Typhoon off the UK the confidence to invest in the platform providing export revenue to the country and ensuring the longevity of our sites.”
Typhoon jets have been produced at Warton in three tranches for more than 25 years, with a total of 160 ordered by the Royal Air Force in that time.
However, Britain’s last order – in the third tranche – was placed in 2009 and no new aircraft have been ordered since. The last jet produced at Warton for the RAF was delivered in 2019.
On Wednesday, BAE Systems stressed that production was set to continue at Warton until at least the late 2020s.
However, it is understood the factory could also benefit from future orders by Qatar, Saudi Arabia, Turkey, Egypt and Poland, among other potential buyers.
Turkey is thought to be lining up to place an order of 40 jets and on Wednesday a Turkish minister claimed the path to a deal had been cleared by the lifting of previous German objections.
If confirmed, that would almost certainly result in more jets being assembled at Warton.
A BAE spokesman said: “Typhoon manufacturing is currently underpinned by the orders from Qatar, Germany and Spain which will ensure continuity of production of major units beyond the late-2020s.”
