Royal Air Force Lakenheath is a military base that is run and operated by the US Air Force.

Lakenheath had been solely used by the RAF during the 1939-45 conflict and was abandoned as an operational base at the end of the war.

The United States Air Force's 48th Bombardment Group, the forerunner of the 48th Fighter Wing, was relocated from Chaumaunt, France, to RAF Lakenheath in 1960 when the USAF took over the base.

It is home to thousands of US service men and women who are stationed there throughout the year.

Search and Rescue teams are looking for the crashed US fighter jet, which is believed to have crashed 74 nautical miles (137km) off the East Yorkshire coast.

A spokeswoman for HM Coastguard said: "The HM Coastguard helicopter from Humberside has been sent along with Bridlington and Scarborough RNLI lifeboats.

"Following a Mayday broadcast by HM Coastguard, other vessels nearby are heading to the area."

RAF Lakenheath's 48th fighter wing has tweeted, confirming news of the crash.

They say that a search and rescue effort is under way to find the pilot who was aboard the jet, which crashed into the North Sea at 09:40 BST.

The BBC's defence correspondent Jonathan Beale reports that the crashed fighter plane was one of four US jets flying in a formation when it crashed at 09:40 BST.

RAF Lakenheath say that the crashed fighter jet had been on a "routine training mission" at the time it was lost in the North Sea.
