The Bureau of Naval Weapons (BuWeps) was part of the United States Navy's material organization between 1959 and 1966, with responsibility for procurement and support of naval aircraft and aerial weapons, as well as shipboard and submarine naval weapons. The bureau was established August 18, 1959, by an Act of Congress. The Act merged the Bureau of Aeronautics (BuAer), which had responsibility for naval aircraft and related systems, and the Bureau of Ordnance (BuOrd), which had responsibility for naval weapons.
