A few quotes from the linked Wikipedia page regarding the base
Loring AFB was carved out of the woods of Maine beginning in the late forties and officially dedicated in 1953.
The host wing for Loring AFB throughout its existence was the 42nd Bomb Wing. The wing originally flew the B-36 Peacemaker, converting later to the B-52 Stratofortress…
The Nuclear Weapons Storage Area at Loring once operated as a separate, top secret facility. Originally called the North River Depot, the remote area to the northeast of Loring’s property was the first U.S. Operational site specifically constructed for the storage, assembly, and testing of atomic weapons…
Since 1981, nearly $300 million in military construction and operations and maintenance funds were spent to upgrade the facilities…
The official base closure date was 30 September 1994.
It is a strange feeling to ride a bicycle around an area where a third of a billion dollars was spent since I was born and is now largely devoid of human presence.
