Revealing the Midget Class Submarines from X-Class to Stickleback. The X Class submarines were conceived during WW2, small craft of around 51ft (16m) long, designed to be towed by a 'mother' submarine with a passage crew on board. Their midget size meant they could attack with stealth, and subsequently return to their towing submarine. Beginning with a look back over the wartime craft, this new study from ex-Submariner Keith Hall charts the evolution of the midget class submarine and how they evolved, from X3 through X and XE, and onto the short lived and unique Stickleback class by the 1950s. Only four Stickleback submarines were ever produced, with grand plans to use them to carry a 15-kiloton nuclear naval mine codenamed Cudgel deep into Soviet harbours. Only one remains, the others having all been scrapped, now residing in the Scottish Submarine Centre in Helensburgh. With a wealth of imagery from the museum archives, this book tells the little-known story of the midget class subs. AUTHOR: Keith Hall was a health physics specialist at HM Naval Base Clyde and served in the Royal Navy for over 30 years, both on the submarines and in on-shore positions. He has written several books on British submarine history, including HMS Dolphin: Gosport's Submarine Base, Submariners' Tales from the Deep, and Polaris: The History of the UK's Submarine Force. He lives in Helensburgh. 111 b/w illustrations
