XT-Craft Midget Submarines
If it is low tide, you might get the chance to see the Royal Naval XT class midget submarines from WW2. You will see the corroded ruins of the two submarines along the coast of Aberlady Bay, Scotland. They were T-Training vessels created by the Vickers’ Armstrong Ltd in the early ‘40s. They took on a mission to fight the Kriegsmarine Tirpitz battleship in September 1943. The crew members succeeded, which made the Royal Navy and Air Force sink the Tirpitz the year after that. Two of the subs were taken to the bay and then moored. The RAF continued to use them for practices and tests.

Sazan Island
Off the coast of Albania, you will see the former home of Soviet Whiskey submarines. Now abandoned, there are old vessels and tunnel networks in the area. The Soviets ran their chemical and biological weapon plants in the area, although it was seized by Albania after abandoning the Warsaw Pact in 1968. It helped increase its navy. By the ‘90s, the subs were obsolete and got neglected before they were completely abandoned. It is now nothing more than an empty base with a gorgeous landscape around it.
