Shown here is a U.S. Coast Guard Grumman HU-16E Albatross and a Sikorsky HH-52A Seaguard in March 1964, probably at Air Station Mobile. The Coast Guard acquired 91 HU-16Es, with the first entering service in 1951. The last Coast Guard HU-16E was retired in 1983. The Coast Guard acquired 99 HH-52As, beginning in 1963, and retired the last one in service in 1989. For over 30 years, these amphibious aircraft were the "workhorses" of the Coast Guard's air fleet.
