UK's only FAW.1 on display at RAFM Cosford. Gloster's last fighter was designed as RAF's first all-weather interceptor, entering frontline service in 1956 with No. 46 Sqn. at RAF Odiham. The FAW.1 was powered by a pair of Armstrong-Siddeley Sapphire Sa.6 10201 and 10301 engines of 36.9 kN thrust each that required a cartridge starter. The aircraft was fitted with the AI.17 radar and 30mm cannon. The initial production run of 40 FAW.1s also served as test platforms. A total of 435 Javelins were built and served in seventeen RAF squadrons plus OCUs, many being converted to different marks.
