The men and women who serve at HMS Gannet, which is based at Prestwick airport, are being awarded the freedom of Ayr.
There are three Sea King Mk5 helicopters at HMS Gannet, painted red and grey to aid visibility.
Tasks range from recovering fallen climbers in winter snow to rescuing injured fishermen offshore.
