British F-class submarine
The F-class submarine was built for the Royal Navy as a coastal submarine based on the doubled hulled V-class submarine (World War I) with very few minor improvements. The only important improvement was the addition of a stern torpedo tube. The F class were ordered as a successor to the E-class submarine, but only three were built out of the ten ordered, the first F1 at Chatham.
