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.
The design was primarily single-hull, with a double hull around the torpedo room and AMS for ballast tanks. The design was improved on the Threshers, the one-off Tullibee, and subsequent attack submarines by relocating the torpedo room into the operations compartment via angled midships torpedo tubes to make room for a large sonar sphere in the ...
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]
This design, already visible on very early submarines, is called a "teardrop hull". It is structurally efficient for withstanding external pressure, and significantly reduces the hydrodynamic drag on the sub when submerged, but decreases the sea-keeping capabilities and increases drag while surfaced.
FORAN system logo. The FORAN system [1] is an integrated CAD/CAM/CAE system developed by SENER for the design and production of practically any naval ship and offshore unit. It is a multidisciplinary and integrated system that can be used in all the ship design and production phases and disciplines.
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. This class of submarine became part of the United ...

Safehull is a software package developed by the ABS in September 1993. It enables the design and evaluation of ship structures, thanks to finite element analysis tools. Possible analyses include: Dynamic load determination; Fatigue analysis [1] [2]
