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 ]

U-995, a U-Boat of WWII, showing the typical combination of ship-like non-watertight outer hull with bulky strong hull below. A submarine hull has two major components, the light hull and the pressure hull. The light hull (casing in British usage) of a submarine is the outer non-watertight hull which provides a hydrodynamically efficient shape ...
The Uzushio-class submarine was a series of seven submarines in service with Japanese Maritime Self Defense Force during the Cold War between 1972 and the mid-1990s. They were the first generation of the teardrop type submarine that valued the underwater performance against that of the preceding conventional-hull type Asashio class.

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 ...
They were the first production warships built with the teardrop-shape hull first tested on the experimental USS Albacore, and the first to combine the control room, attack center, and conning tower in the same space in the hull. They were of double hull design with 1.5-inch thick HY80 steel.
