Borrowed history.(tbh its all pretty simialar)
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!
