Originally designated as the SA-16 for the USAF and the JR2F-1 and UF-1 for the USN and USCG, it was redesignated as the HU-16 in 1962. An improvement of the design of the Grumman Mallard, the Albatross was developed to land in open ocean situations to accomplish rescues. Its deep-V hull cross-section and keel length enable it to land in the open sea. The Albatross was designed for optimal 4-foot (1.2 m) seas, and could land in more severe conditions, but required JATO (jet-assisted take off, or simply booster rockets) for takeoff in 8–10-foot (2.4–3.0 m) seas or greater. The Royal Canadian Air Force operated Grumman Albatrosses with the designation "CSR-110". In 1970, Conroy Aircraft marketed a remanufactured HU-16A with Rolls-Royce Dart turboprop engines as the Conroy Turbo Albatross, but only one prototype was ever built.
