British Hovercraft 7 would have been the SR.N7. Built in 1969 at Southampton and Cowes for the Interservice Hovercraft Unit, which was based at our site at Lee-on-the-Solent. From here the craft flew on numerous sorties including to the Arctic Circle and back, proving the hovercraft on rugged ice and snow. In the early 70's the craft demonstrated to NATO along the North American seaboard leading to the US Navy starting their own hovercraft landing craft programme, leading to a fleet of 98 one hundred tonners.
