Los Alamos National Laboratory (LANL)

Arial view of the facility

The Los Alamos Laboratory, also known as SiteY or Project Y, was built in 1943 to design and build an atomic bomb. After World War II, LANL scientists continued to perfect US weapons during the cold war. Today, LANL is a security research institution, with the responsibility of ensuring the safety, security, and reliability of the nation’s nuclear deterrent.
