United States Coast Guard first turbo shaft helicopter.
The photo pictured is a US Coast Guard HH-52A
which was put in service with the original 3 blade
system that came from the S-55(H-19).
The Coast Guard bought 96 of the "A" model and
flew them from approximately 1961 to 1985.
The model was retired with the same designation
HH-52A it received originally.
The paint scheme pictured was the first of several
styles. In 1967 the aircraft received the new red,
white and blue "slash" the Coast Guard still retains.
HH-52's that were deployed to the ice caps on ice
breakers were painted orange with a white "slash"
on the tail. This tradition is still praticed today.

In order to comply with US law, the majority of the helicopters value had to be produced locally,
most notably the substitution of Avco Lycoming engines in place of the original Turboméca units
