RAF emergency: UK Typhoon jet squawks 7700 code as it circles and drops to 2,000ft

The warplane sent the signal today as it flew over Sutton on Sea. Its route shows it dropping to some 2,000 feet above sea level. The RAF has been approached for comment.

The 7700 squawk code is designed to alert Air Traffic Control to an aircraft in distress and can often be used to indicate a technical or engineering issue with an aircraft.

Flight tracking platform adsbexchange.com shows the Typhoon looping over the sea near Sutton on Sea, Chapel St Leonards and Skegness at an altitude below 2,500ft with a groundspeed up to 500mph.

The Typhoon model is a fourth-generation, multi-role combat aircraft with its most essential role to provide quick reaction alert in UK airspace.

Typhoon detachments have also reinforced NATO defences over the Baltic Sea and Black Sea, according to the RAF.

The Government announced last week that Typhoon fighter jets will be fitted with the world’s most advanced radar as part of a £2.35billion investment.

In its announcement, the Government said the state-of-the-art European Common Radar System (ECRS) Mk 2 radar will transform the Eurofighter Typhoon’s control of the air as well as allow the aircraft to simultaneously detect, identify and track multiple targets in the air and on the ground.

Minister for Defence Procurement, Jeremy Quin, said: “It’s vital the UK remains at the forefront of military capabilities to be able to deter and defend.

“These technological enhancements will maintain the cutting-edge capabilities of Eurofighter Typhoon and help underpin the development path towards the Future Combat Air System.”


Britain said on Monday it was collaborating with Japan and existing partner Italy on its next-generation fighter jet programme, with joint concept analysis expected to lead to decisions on deeper partnerships by the end of the year.

London and Tokyo are reportedly close to an agreement to merge their next-generation Tempest and F-X fighter jet programmes, with the two countries aiming for a deal on a new joint project by year-end.

The UK and defence giant BAE Systems said a Tempest demonstrator would fly within the next five years, becoming the country’s first combat air demonstrator since the Typhoon nearly 40 years ago.

BAE said at Farnborough it will be a piloted, supersonic, aircraft testing a range of new technologies, including integration of stealth compatible features.

Britain wants the new fighter to be in service by 2035 and is pursuing a programme separate from a Franco-German-Spanish plan.

As with the UK, both Japan and Italy operate F-35 fighter jets and the nations have undertaken joint exercises together.

Richard Berthon, UK Director, Future Combat Air, said Britain was talking to serious countries with serious ambitions to invest.

He said talks with Japan were going better than to plan.

Tempest has a Government budget of £2billion until 2025. Other partners include Leonardo UK, MBDA and Rolls-Royce.

Britain and Sweden have also signed a memorandum of understanding to work on joint combat air development and acquisition.
