First flown 1963, and prided at the time for being the world's largest hovercraft, the SRN3 was developed for use as a military high-speed, amphibious, load carrying vehicle, and as a military patrol boat with the capability to lower two water screws driven by their own power units, for accurate low-speed manoevering. The SRN3 was extensively trialled by the British Inter-Service Hovercraft Trials unit for its amphibious and over-water roles (Hovercraft Museum, 2007c ; BHC Publication , available from The Hovercraft Museum ).
