Type 24 Eclipse Class Frigate
HMS Eclipse, 1991
As a growing oil and gas producing nation during the 1970s the need to patrol and protect the North Sea oilfields saw the need for more vessels. As well as the OPV fleet, a small light patrol frigate was desired. At the same time the Towed Array Ship was steadily growing into the specialised Type 23 Duke when the Leanders were coming to retirement age and costs were a concern. Yarrow was asked to design a cheap frigate and the Type 24 was the result. Lacking the expensive powerplant and electronic features of the Duke the costs were kept down. An eye was also kept on export orders. The machinery fit was half that of a Type 23 with emphasis on lower speed and good endurance. and a batch of 6 were ordered alongside 16 Dukes to form a modern fleet of 14 frigates to replace the last of the Leanders and serve alongside the Type 21s and Type 22s.
