The Gato class of submarines was built for the United States Navy and launched in 1941–1943; they were the first mass-production U.S. submarine class of World War II. Together with their near-sisters the Balao and Tench classes, their design formed the majority of the United States Navy's World War II submarine fleet. Named after the lead ship of the class, USS Gato, the Gatos and their successors formed the core of the submarine service that was largely responsible for the destruction of the Japanese merchant marine and a large portion of the Imperial Japanese Navy in World War II. Gato's name comes from a species of small catshark. Like most other U.S. Navy submarines of the period, boats of the Gato class were given the names of marine creatures. In some references, the Gatos are combined with their successors, especially the Balao class.
USS Grampus may refer to:
Two submarines of the United States Navy have been named USS Sand Lance for the sand lance.
USS Grampus (SS-523), a Tench-class submarine, was the seventh ship of the United States Navy to be named for two members of the dolphin family (Delphinidae): Grampus griseus, also known as Risso's dolphin, and orca, also known as the "Killer Whale." Her keel was laid down on 8 February 1944 at Boston Navy Yard. She was launched on 16 December 1944, but World War II ended before she was completed, and she sat idle until construction resumed in 1948. On 26 October 1949, she was both christened and commissioned, with Commander George F. Sharp in command.
The Greater Underwater Propulsion Power Program (GUPPY) was initiated by the United States Navy after World War II to improve the submerged speed, maneuverability, and endurance of its submarines.
The Balao class was a successful design of United States Navy submarine used during World War II, and with 120 boats completed, the largest class of submarines in the United States Navy. An improvement on the earlier Gato class, the boats had slight internal differences. The most significant improvement was the use of thicker, higher yield strength steel in the pressure hull skins and frames, which increased their test depth to 400 feet (120 m). Tang actually achieved a depth of 612 ft (187 m) during a test dive, and exceeded that test depth when taking on water in the forward torpedo room while evading a destroyer.
Tench-class submarines were a type of submarine built for the United States Navy (USN) between 1944 and 1951. They were an improvement over the Gato and Balao classes, only about 35 to 40 tons larger, but more strongly built and with a slightly improved internal layout. One of the ballast tanks was converted to carry fuel, increasing range from 11,000 nautical miles to 16,000 nautical miles. This improvement was also made on some boats of the previous two classes. Further improvements were made beginning with SS-435, which are sometimes referred to as the Corsair class. Initial plans called for 80 to be built, but 51 were cancelled in 1944 and 1945 when it became apparent that they would not be needed to defeat Japan. The remaining 29 were commissioned between October 1944 (Tench) and February 1951 (Grenadier). The last submarine of the Tench class, as well as the last submarine which served during World War II, remaining in service with the U.S. Navy was USS Tigrone (AGSS-419) which was decommissioned on 27 June 1975.
USS Sand Lance (SS-381), a Balao-class submarine, was the first ship of the United States Navy to be named for the sand lance, a member of the family Ammodytidae. Her keel was laid down on 12 March 1943 by the Portsmouth Naval Shipyard in Kittery, Maine. She was launched on 25 June 1943 sponsored by Mrs. Edith Burrows, and commissioned on 9 October 1943 at Portsmouth, with Commander Malcolm Everett Garrison in command.
The Brazilian Navy is the naval service branch of the Brazilian Armed Forces, responsible for conducting naval operations. The Brazilian Navy is the largest navy in South America and in Latin America, and the second largest navy in the Americas, after the United States Navy.
USS Grenadier (SS-525), a Tench-class submarine, was the second ship of the United States Navy to be named for the grenadier, a soft-finned deep sea fish of the Macrouridae with a long, tapering body and short, pointed tail family, also known as rattails.
Narcíso Monturiol may refer to one of the following submarines of the Spanish Navy named after submarine pioneer Narcís Monturiol:
Bahia was the lead ship of a two-vessel class of cruisers built for Brazil by the British company Armstrong Whitworth. Crewmen mutinied in November 1910 aboard Bahia, Deodoro, Minas Geraes, and São Paulo, beginning the four-day Revolta da Chibata. Brazil's capital city of Rio de Janeiro was held hostage by the possibility of a naval bombardment, leading the government to give in to the rebel demands which included the abolition of flogging in the navy. During the First World War, Bahia and her sister ship Rio Grande do Sul were assigned to the Divisão Naval em Operações de Guerra, the Brazilian Navy's main contribution in that conflict. The squadron was based in Sierra Leone and Dakar and escorted convoys through an area believed to be heavily patrolled by U-boats.
The Bahia class was a pair of scout cruisers built for Brazil by Armstrong Whitworth in the United Kingdom, based on a design that borrowed heavily from the British Adventure-class scout cruisers. The class comprised the lead ship Bahia and her sister Rio Grande do Sul, along with a canceled third ship, Ceara. Both were named after states of Brazil. As a class, they were the fastest cruisers in the world when commissioned, and the first in the Brazilian Navy to use steam turbines for propulsion.
Two vessels of the Royal Canadian Navy have been named HMCS Rainbow, after the rainbow.
Rio Grande do Sul was a Bahia-class cruiser built for the Brazilian Navy in 1909–10.
Several ships of the Brazilian Navy have been named Bahia, after the state of Bahia:
