At its height, the RAF operated four Whirlwind 10 sqns in Borneo: 103, 110 both based at Seletar with detachments in Borneo and 225 and 230. The former was based at Kuching and the latter at Labuan.
225 was disbanded on 1 Nov 65 and its aircraft distributed amongst 103 and 110. 230 Sqn went back to UK in the autumn of '66 and it took its aircraft with it in the back of several Belfasts.
These RAF Whirlwinds were all jet powered and hence superior to the S55 and also earlier piston powered versions of the Whirlwind (Mk 2 & 4). Many Whirlwinds were re-engined and a number, in the XP, XR and one XS (412) series were new build. The RN used the Mk7 but in the main they had Wessex, first the single engined Mk 1 and later the twin engined Mk 5.
