Operation Source
Operation Source was a series of attacks to neutralise the heavy German warships – ''Tirpitz'', ''Scharnhorst'' and ''Lützow'' – based in northern Norway, using X-class midget submarines. The attacks took place in September 1943 at Kaafjord and succeeded in keeping ''Tirpitz'' out of action for at least six months. The concept for the attack was developed by Commander Cromwell-Varley, with support of Max Horton, Flag Officer Submarines, and Prime Minister Winston Churchill. The operation was directed from HMS ''Varbel'', located in Port Bannatyne on the Isle of Bute. ''Varbel'' (named after Commanders Varley and Bell, designers of the X-Craft prototype) was the on-shore headquarters for the 12th Submarine Flotilla (midget submarines). It had been a luxury 88-bedroom hotel (the Kyles Hydropathic Hotel) requisitioned by the Admiralty to serve as the flotilla’s headquarters. All X-craft training and preparation for X-craft attacks (including that on ''Tirpitz'') was c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sullom Voe
Sullom Voe is an inlet of the North Sea between the parishes of Delting and Northmavine in Shetland, Scotland. It is a location of the Sullom Voe oil terminal and Shetland Gas Plant. The word Voe is from the Old Norse ' and denotes a small bay or narrow creek. The head of the voe makes up the eastern side of Mavis Grind. The Voe, the longest in Shetland, and partially sheltered by the island of Yell was used as a military airfield during World War II both by the Royal Air Force and the Royal Norwegian Air Force as a location for flying boats. With the coming of the oil terminal, the remains of the airfield were upgraded and modernised to create Scatsta Airport which was primarily used to service the terminal. The first crude oil was discovered in the North Sea in 1969, and soon thereafter construction began on the oil terminal at Sullom Voe, north east of the village of Brae, which became operational in 1975 and was completed in 1982, becoming the largest in Europe.

Consolidated PBY Catalina
The Consolidated PBY Catalina is a flying boat and amphibious aircraft that was produced in the 1930s and 1940s. In Canadian service it was known as the Canso. It was one of the most widely used seaplanes of World War II. Catalinas served with every branch of the United States Armed Forces and in the air forces and navies of many other nations. The last military PBYs served until the 1980s. As of 2021, 86 years after its first flight, the aircraft continues to fly as a waterbomber (or airtanker) in aerial firefighting operations in some parts of the world. None remain in military service. Design and development Background The PBY was originally designed to be a patrol bomber, an aircraft with a long operational range intended to locate and attack enemy transport ships at sea in order to disrupt enemy supply lines. With a mind to a potential conflict in the Pacific Ocean, where troops would require resupply over great distances, the U.S. Navy in the 1930s invested millions ...

Grumman Martlet
The Grumman F4F Wildcat is an American carrier-based fighter aircraft that entered service in 1940 with the United States Navy, and the British Royal Navy where it was initially known as the Martlet. First used by the British in the North Atlantic, the Wildcat was the only effective fighter available to the United States Navy and Marine Corps in the Pacific Theater during the early part of the Second World War. The disappointing Brewster Buffalo was withdrawn in favor of the Wildcat and replaced as aircraft became available. With a top speed of , the Wildcat was outperformed by the faster (), more maneuverable, and longer-ranged Mitsubishi A6M Zero. US Navy pilots, including John "Jimmy" Thach, a pioneer of fighter tactics to deal with the A6M Zero, were greatly dissatisfied with the Wildcat's inferior performance against the Zero in the battles of the Coral Sea and Midway. The Wildcat has a claimed air combat kill-to-loss ratio of 5.9:1 in 1942 and 6.9:1 for the entire war.Po ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
