In naval terminology, a destroyer is a fast, maneuverable, long-endurance warship intended to escort larger vessels in a fleet, convoy, or carrier battle group and defend them against a wide range of general threats. They were originally conceived 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.

A warship or combatant ship is a ship that is built and primarily intended for naval warfare. Usually they belong to the armed forces of a nation. As well as being armed, warships are designed to withstand damage and are typically faster and more maneuverable than merchant ships. Unlike a merchant ship, which carries cargo, a warship typically carries only weapons, ammunition and supplies for its crew. Warships usually belong to a navy, though they have also been operated by individuals, cooperatives and corporations.
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 was a class of 96 patrol frigates which 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.

Combined gas turbine and gas turbine (COGAG) is a type of propulsion system for ships using two gas turbines connected to a single propeller shaft. A gearbox and clutches allow either of the turbines to drive the shaft or both of them combined. Marine usage of COGAG systems are similar to those found ashore.
HMS Grenville was the second ship of this name to serve with the Royal Navy in the Second World War. Grenville and seven other U-class destroyers were ordered as part of the Emergency Programme.
