Technical research ships were used by the United States Navy during the 1960s to gather intelligence by monitoring, recording and analyzing wireless electronic communications of nations in various parts of the world. At the time these ships were active, the mission of the ships was covert and discussion of the true mission was prohibited. The mission of the ships was publicly given as conducting research into atmospheric and communications phenomena. Their designation was AGTR – Auxiliary, General, Technical Research – but it was more or less an open secret that this was a euphemism and they were commonly referred to as "spy ships".

Aircraft repair ship is a naval auxiliary ship designed to provide maintenance support to aircraft. Aircraft repair ships provide similar services to seaplane tenders, that also cared for the crew. Aircraft repair ships had their own stores of spare parts, like a depot ship. Aircraft repair ships had repair personnel and equipment to repair failures or battle damage on aircraft. Aircraft repair ships also did regular aircraft maintenance.
