The Green Cheese missile was a British radar-guided anti-ship tactical nuclear warhead missile project of the 1950s. It was developed by Fairey Aviation to be used by the Fairey Gannet shipborne anti-submarine warfare aircraft, and was originally called Fairey Project 7. Unfortunately, the missile's 3,800 lb (1720 kg) weight proved to be too heavy for the Gannet, and would have required modifications to the Gannet's bomb bay to expose the missiles' seeker heads to the target before launch. The missile project continued, since the Blackburn Buccaneer naval strike aircraft had a rotating bomb bay which was ideally suited to the task.
