What was the name of the WWII U.S.A.F. base in England code named "Valley" In Northwest England, Lancashire?

Was called Burtonwood...on the outskirts of Warrington, Lancashire. The area it covered was simply HUGE!..large enough to build a small town . Infact in the 80's they sold off most of the land for housing /industry /retail. I worked there in he 80's for a housing developer . There was still a small USAF base there.

As you know this was the main landing area for the USAF during WW2 for armaments etc.

I see this site loads . its visible when you travel on the M62 out/in to Liverpool. The motorway services Burtonwood are very close . I heard during the cold war there where nuclear weapons held there,therefore causing Liverpool to be on the Soviet bomb list . The site still has visible massive aircraft hangers wich always make me shudder to think what the hell was once held there . Is it still US owned ?

Are you sure it was in northwest England?

The Usaf used the raf base at Valley on Angelsey, Wales

Burtonwood, closed in 1993

It's definitely RAF Burtonwood; we used to send faulty electrical goods up there and had two enormous bomber hangars to store them in.
