A carrier battle group (CVBG) is a naval fleet consisting of an aircraft carrier capital ship and its large number of escorts, together defining the group. The CV in CVBG is the United States Navy hull classification code for an aircraft carrier.
In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish Navy as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War.
A frigate is a type of warship. In different eras, the roles and capabilities of ships classified as frigates have varied somewhat.
A corvette is a small warship. It is traditionally the smallest class of vessel considered to be a proper warship. The warship class above the corvette is that of the frigate, while the class below was historically that of the sloop-of-war. The modern types of ships below a corvette are coastal patrol craft, missile boat and fast attack craft. In modern terms, a corvette is typically between 500 tons and 2,000 tons, although recent designs may approach 3,000 tons, which might instead be considered a small frigate.
The Hellenic Navy is the naval force of Greece, part of the Hellenic Armed Forces. The modern Greek navy historically hails from the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy it was known as the Royal Hellenic Navy.
Destroyer escort (DE) was the United States Navy mid-20th-century classification for a 20-knot warship designed with the endurance necessary to escort mid-ocean convoys of merchant marine ships.
The Tacoma class of patrol frigates served in the United States Navy during World War II and the Korean War. Originally classified as gunboats (PG), they were reclassified as patrol frigates (PF) on 15 April 1943. The class is named for its lead ship, Tacoma, a Maritime Commission (MARCOM) S2-S2-AQ1 design, which in turn was named for the city of Tacoma, Washington. Twenty-one ships were transferred to the British Royal Navy, in which they were known as Colony-class frigates, and twenty-eight ships were transferred under Lend-Lease to the Soviet Navy, where they were designated as storozhevoi korabl, during World War II. All Tacoma-class ships in US service during World War II were manned by United States Coast Guard crews. Tacoma-class ships were transferred to the United States Coast Guard and various navies post-World War II.
USS Heermann (DD-532) was a World War II-era Fletcher-class destroyer in the service of the United States Navy. The ship entered service in 1943 and took part in several battles during World War II in the Pacific theatre of operations, including the Philippines campaign, Battle off Samar and the Battle of Iwo Jima among others. Heermann gained fame during the "last stand of the Tin Can Sailors" in which she and several other destroyers of Task Unit 77.4.3 engaged a far superior Japanese task force during the Battle off Samar in October 1944. Heermann was the only American destroyer of "Taffy 3" to survive the engagement. Following the end of the war in 1945, the ship was placed in reserve from 1946 to 1951, when the destroyer was reactivated. Heermann remained in active service until 1957, when the ship was returned to the reserve. In 1961, Heerman was loaned to Argentina and was renamed ARA Almirante Brown (D-20) while in service with the Argentinian Navy. Almirante Brown remained in Argentinian service until 1982, when the ship was decommissioned.
The Buckley-class destroyer escorts were 102 destroyer escorts launched in the United States in 1943–44. They served in World War II as convoy escorts and anti-submarine warfare ships. The lead ship was USS Buckley which was launched on 9 January 1943. The ships had General Electric steam turbo-electric transmission. The ships were prefabricated at various factories in the United States, and the units brought together in the shipyards, where they were welded together on the slipways.
Mark 32 Surface Vessel Torpedo Tubes is a torpedo launching system designed for the United States Navy.
The Cannon class was a class of destroyer escorts built by the United States primarily for antisubmarine warfare and convoy escort service during World War II. The lead ship, USS Cannon, was commissioned on 26 September 1943 at Wilmington, Delaware. Of the 116 ships ordered, 44 were cancelled and six were commissioned directly into the Free French Forces. Destroyer escorts were regular companions escorting vulnerable cargo ships.
USS Thornhill (DE-195) was a Cannon-class destroyer escort in service with the United States Navy from 1943 to 1947. In 1951, the ship was transferred to the Italian Marina Militare and renamed Aldebaran. The ship remained in service until 1976 when she was sold for scrap.
USS Gandy (DE-764) was a Cannon-class destroyer escort in service with the United States Navy from 1944 to 1946. In 1951, she was transferred to Italy, where she served as Altair until she was stricken and sunk as a target in 1971.
When the United States entered World War II at the end of 1941, the United States Navy found itself deficient in ocean escort-type vessels. A crash building program was instituted; but, to meet more immediate needs, the government contracted with shipbuilding firms in England and Canada to build Flower-class corvettes. Vim (PG-99) was one of those British-type escorts. She was launched on 1 April 1943 at the Collingwood Shipyard in Collingwood, Ontario. Nine days later, however, she was transferred to the Royal Navy under the terms of the lend-lease agreement in return for another Flower-class corvette then under construction in Canada. The British renamed her HMS Statice, and she served the Royal Navy under the name through World War II. On 21 June 1946, she was returned to the United States Navy. Though carried on the Navy list as PG-99, the corvette never saw active service with the United States Navy. She was sold on 7 May 1947. To whom she was sold and to what purpose she was put is unknown.
The Van Amstel class was a class of six frigates that were built during the Second World War in the United States and served as Cannon-class destroyer escort during that war. After the war the destroyer escorts were loaned to the Dutch navy as part of the MDAP and from 1950 to 1967 served as the Van Amstel-class frigates.
