A French class of destroyers that were built in the 1950's, the last one was completed to a much modified design, and in fact was a test bed for new equipment.
The La Galissonniere, also known as T-56 type was unique, and was in fact the first destroyer in French naval service to carry a helicopter, and for that a folding hangar was provided, and when the wall were folded down they became part of the landing area.
The helicopter is SA-3150 a modified Alouette III with floats, a small search radar amd MAD on the port-side and one anti-submarine torpedo on the starboard side. Later helicopters had wheels
