At St Margaret's Bay there is the underground deep shelter for St Margarets 5.5" Battery. This site was the first one to use the unrotated projectile known as the Z - Rocket which was a anti - aircraft (AA) weapon. It was officially known as a UP or unrotated projectile. It was not particularly accurate, but the thinking was that if fired in large enough amounts an enemy plane just might get hit
