RAF Waddington's runway to get £35m upgrade
More than £35m is to be spent on rebuilding and lengthening the runway at RAF Waddington in Lincolnshire.
The Ministry of Defence (MoD) said the investment would extend the runway's operational life by a further 25 years.
It said it was vital that the base, which is the "eyes and ears" of the UK's armed forces, continued to provide surveillance and reconnaissance in support of military operations.
Some improvements will also be made to facilities on the site.
RAF Waddington uses a range of airborne intelligence systems, including the Boeing Rivet Joint intelligence aircraft, which is due to enter service later this year.
Station commander Rich Barrow said: "The existing 9,000ft-long runway has reached the end of its lifespan.
"For RAF Waddington to continue to deliver on its mission the runway infrastructure must be modified to support our world class aircraft, and our highly qualified pilots and ground staff."
It is the first major upgrade at the base since the 1960s.
Work starts in July and is expected to be completed by late summer 2015.
During the rebuild, aircraft will be temporarily relocated to other bases across the county.
