The Angled Deck Carrier 1955 US Navy Training Film MN-8107 (Patreon)

Originally a public domain film from the US Navy, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

The flight deck of an aircraft carrier is the surface from which its aircraft take off and land, essentially a miniature airfield at sea. On smaller naval ships which do not have aviation as a primary mission, the landing area for helicopters and other VTOL aircraft is also referred to as the flight deck. The official U.S. Navy term for these vessels is "air-capable ships"...

The first flight decks were inclined wooden ramps built over the forecastle of warships. Eugene Ely made the first fixed-wing aircraft take-off from a warship from USS Birmingham on 14 November 1910...

The angled flight deck was invented by Royal Navy Captain (later Rear Admiral) Dennis Cambell, as an outgrowth of design study initially begun in the winter of 1944–1945. A committee of senior Royal Navy officers decided that the future of naval aviation was in jets, whose higher speeds required that the carriers be modified to "fit" their needs.

With this type of deck – also called a "skewed deck", "canted deck", "waist angle deck", or the "angle" – the aft part of the deck is widened, and a separate runway is positioned at an angle from the centreline.

The angled flight deck was designed with the higher landing speeds of jet aircraft in mind, which would have required the entire length of a centreline flight deck to stop. The design also allowed for concurrent launch and recovery operations, and allowed aircraft failing to connect with the arrestor cables to abort the landing, accelerate, and relaunch (bolter) without risk to other parked or launching aircraft.

The redesign allowed for several other design and operational modifications, including the mounting of a larger island (improving both ship-handling and flight control), drastically simplified aircraft recovery and deck movement (aircraft now launched from the bow and re-embarked on the angle, leaving a large open area amidships for arming and fueling), and damage control. Because of its utility in flight operations, the angled deck is now a defining feature of STOBAR and CATOBAR equipped aircraft carriers.

The angled flight deck was first tested in 1952 on HMS Triumph by painting angled deck markings onto the centerline of the flight deck for touch-and-go landings. This was also tested on USS Midway the same year.

Despite the new markings, in both cases the arresting gear and barriers were still aligned with the centerline of the original deck. From September to December 1952, USS Antietam had a rudimentary sponson installed for true angled-deck tests, allowing for full arrested landings, which proved during trials to be superior. In 1953, Antietam trained with both U.S. and British naval units, proving the worth of the angled-deck concept.[20] HMS Centaur was modified with overhanging angled flight deck in 1954.

The U.S. Navy installed the decks as part of the SCB-125 upgrade for the Essex class and SCB-110/110A for the Midway class. In February 1955, HMS Ark Royal became the first carrier to be constructed and launched with an angled deck, rather than having one retrofitted. This was followed in the same year by the lead ships of the British Majestic class (HMAS Melbourne) and the American Forrestal class (USS Forrestal)...
