The standing up of the new Squadron also coincides with RAF Lossiemouth marking its 80th anniversary.
Some of the Squadron’s aircraft will be painted in distinctive markings to identify them as training ‘adversaries’, in their role as ‘aggressors’.
They will provide a sterner training test to RAF and NATO fast-jet pilots, playing the role of opposing aircraft which match their speed and manoeuvrability whilst using the latest real-world dogfighting and air combat tactics against them.
This morning the Standard of @IXBSqn was handed over to the new OC, Wg Cdr Simon Batt, marking the re-role of the Sqn from Tornado to Typhoon.
We now have four front-line Typhoon Sqns in Scotland, delivering air power in operations worldwide.
Speaking at the ceremony, Chief of the Air Staff, Air Chief Marshal Sir Stephen Hillier, said "RAF Lossiemouth has and will continue to play a key role in the defence of the United Kingdom":
"Today’s transition of IX Sqn from Tornado to Typhoon is one important part of the expansion of RAF Lossiemouth which will see the number of service personnel here increase to some 2,300, supported by a further 1,800 MOD civilian and contractor staff.
"I am proud to see our Combat Air capabilities continue to grow, a necessity as they will undoubtedly continue to be in exceptionally high demand on operations, here in the UK and across the world."
Quick Reaction Alert involves the entire UK Air Defence system being on standby for immediate readiness, 24/7, 365 days a year. It involves aircraft from RAF Lossiemouth and RAF Coningsby, which are tasked with protecting northern and southern UK airspace respectively.
Typhoons from RAF Lossiemouth have been scrambled four times in recent months, as long-range Russian bombers approached UK airspace.
