COUNTY Class

 destroyer

The COUNTY class were large destroyers essentially built around the requirements of the new Seaslug missile system; the missile magazine was located forward, and the missiles were brought up and run aft through a tunnel in which checkouts would be performed, wings and fins fitted, until finally run out on the launcher located right aft at the stern. The Seaslug missile was intended initially as an anti-aircraft missile, but in view of its mass and impressive kinetic energy on impact, later versions were improved to have surface warfare capability as well. Powered by a combined plant of steam and gas turbines (COSAG), these ships also carried a hangar for a Wessex helicopter, and were later fitted with the new Exocet missile, all firsts for British warships. They were also fitted with good command facilities. Specialized as these ships were to carry the Seaslug missile, the only RN ships to ever do so, these ships were of decreasing value in the late 1970's and early 1980's, and all were paid off from RN service by the mid-80s. ANTRIM and GLAMORGAN were both damaged in the Falkland's War. FIFE and ANTRIM remained in service with the Chilean Navy into the 21st century, under new names.

A port-stern quarter view of ANTRIM. This photo shows the Seaslug launcher at the stern to good effect, and also the Type 901 Seaslug tracker radar can be seen atop the hangar. As one of the last four of the class, she is fitted with the Type 965 AKE-2 "double-bedstead" radar antenna on the aft mast. M.D. Thomas photo.
Denvonshire
A broadside view of DEVONSHIRE taken in Portsmouth. HMS VICTORY can be seen in the background. The Type 965 AKE-1 "single-bedstead" radar, typical of the first four members of the class, is atop the aft mast. M.D. Thomas photo.
Fife
Taken on the port side of FIFE, this photo shows the helicopter hangar for a single Westland Wessex helicopter. The port Seacat missile launcher can be seen in the centre of the photo. The Type 277 radar antenna can be seen to the left of the photo, under and aft of the Type 965. A single 20mm mount is directly above the Seacat launcher, above the hangar.  M.D. Thomas photo.
Glamorgan
HAMPSHIRE is shown here, illustrating the appearance of the ships when fitted with both twin 4.5" mounts. The 992Q or 993 radar antenna can be seen at the top of the forward mast. M.D. Thomas photo.
Hampshire
GLAMORGAN after the replacement of 'B' mount with four Exocet box launchers. M.D. Thomas photo.
Kent
A nice view of KENT. M.D. Thomas photo.
London
LONDON steams by the camera. The hangar door is closed in this picture, which can be contrasted to the open door in the earlier photo of FIFE. M.D. Thomas photo.
Norfolk
A close-up of the Seaslug launcher on NORFOLK. The missiles were assembled within the superstructure, and then slid out through ports (to the right of the launcher in this photo) into the launcher. M.D. Thomas photo.
