"RAF" Mildenhall, only 5 miles from "RAF" Lakenheath, Mildenhall is a key USAF installation, providing air transport, aerial refuelling, and support for special-services missions.
The USAF has stated that it plans to pull out of airbases at Mildenhall, Alconbury and Molesworth, although the timing seems uncertain. The MOD will then sell the land to build housing.
