TARTAR

TRIBAL Class (Type 81)

general purpose frigate

The original design of these relatively small general purpose frigates went through a number of revisions before the ships themselves arrived on the scene. In RN parlance of the time, they were called "Sloops" to avoid the conotations that the term "frigate" carried as being a single purpose design. They carried one-half of the COSAG plant installed in the COUNTY class, and therefore acted as prototypes for this powerplant. Small ships, without much room for upgrade, all were paid-off starting in 1979 due to the RN's manpower crisis. Some were reactivated after the Falkland's War to make up for attrition during that war, but all were paid off again by 1985.

Ashanti
Aft-starboard quarter view of ASHANTI. The Seacat launcher seen over the aft gun is on another ship tied up on the inside. A Type 199 VDS set is fitted to the stern. ASHANTI's own starboard Seacat CRBF director is abreast the aft funnel on a platform. M.D. Thomas photo.

ESKIMO taken from the forward port quarter. There is no Seacat or associated fire control radars fitted in this photo. M.D. Thomas photo.
Eskimo
A good aft starboard quarter view of ESKIMO, again with no Seacat. M.D. Thomas photo.
Gurkha
A view of GURKHA's forward superstructure. The ship's two main guns were taken from paid off Second World War era C class destroyers. The Type 903 tracker and MRS3 director can be seen above the bridge, just below the Type 993 radar. The Type 965 AKE-1 "bedstead" radar is at the masthead, and the port Seacat quad launcher is visible just forward of the break down to the quarterdeck, and the ship's boat.  M.D. Thomas photo.
Nubian
A Wasp helicopter on the landing pad of NUBIAN, and the aft 4.5" gun. The landing pad was a lift that would lower the helicopter into the hangar, and then form the roof of the hangar. M.D. Thomas photo.
Tartar
TARTAR with a Wasp on deck. The triple barrels of the Limbo ASW mortar can just be seen ahead of the helicopter.  M.D. Thomas photo.
