A teardrop hull is a submarine hull design which emphasizes submerged performance over surfaced performance. It was somewhat commonly used in the early stages of submarine development, but was gradually abandoned in the early 20th century in favour of designs optimized for high performance on the surface as a result of changes in operational doctrine.
USS Albacore (AGSS-569) is a unique research submarine that pioneered the American version of the teardrop hull form (sometimes referred to as an "Albacore hull") of modern submarines. The revolutionary design was derived from extensive hydrodynamic and wind tunnel testing, with an emphasis on underwater speed and maneuverability. [ 4 ]
The greatest alteration was the new tear-drop hull, pioneered by the conventionally powered USS Albacore, and designed for optimum performance underwater. The Albacore was the world underwater speed record holder in 1966 at 34.8 knots, around 40 mph, outpacing all nuclear powered Subs. The new hull's only protrusions were the sail and diving ...
Known as "pig boats", or "boats", due to foul living quarters and unusual hull shape. O-11 through O-16 (built by Lake Torpedo Boat Company) also known as the "modified O-class". Modified boats proved to be disappointing and were scrapped in 1930; Lake went out of business in 1925.
The hull and innovative internal arrangement were similar to the diesel-powered Barbel class that were built concurrently. The design of the Skipjacks was very different from the Skate-class submarines that preceded the Skipjacks. Unlike the Skates, this new design was maximized for underwater speed by fully streamlining the hull like a blimp ...
