Destroyer escort in the context of "John C. Butler-class destroyer escort"

During the 18th and 19th centuries, a sloop-of-war was a warship of the Royal Navy with a single gun deck that carried up to 18 guns. The rating system of the Royal Navy covered all vessels with 20 or more guns; thus, the term encompassed all unrated warships, including gun-brigs and cutters. In technical terms, even the more specialised bomb vessels and fire ships were classed by the Royal Navy as sloops-of-war, and in practice these were employed in the role of a sloop-of-war when not carrying out their specialised functions.

In World War I and World War II, the Royal Navy reused the term "sloop" for specialised convoy-defence vessels, including the Flower class of the First World War and the highly successful Black Swan class of the Second World War, with anti-aircraft and anti-submarine capabilities. They performed similar duties to the destroyer escorts of the United States Navy, and also performed similar duties to the smaller corvettes of the Royal Navy.

USS Johnston (DD-557) was a Fletcher-class destroyer built for the United States Navy during World War II. She was named after Lieutenant John V. Johnston, an officer of the US Navy during the American Civil War. Johnston was laid down in May 1942 and was launched on 25 March 1943. She entered active duty on 27 October 1943 under the command of Lieutenant Commander Ernest E. Evans and was assigned to the US Pacific Fleet. Johnston provided naval gunfire support for American ground forces during the Gilbert and Marshall Islands campaign in January and February 1944 and again, after three months of patrol and escort duty in the Solomon Islands, during the recapture of Guam in July. Thereafter, Johnston was tasked with escorting escort carriers during the Mariana and Palau Islands campaign and the liberation of the Philippines.

On 25 October 1944, while assigned as part of the escort to six escort carriers, Johnston, two other Fletcher-class destroyers, and four destroyer escorts were engaged by a large Imperial Japanese Navy flotilla. In what became known as the Battle off Samar, Johnston and the other escort ships charged the Japanese ships to protect nearby US carriers and transport craft. After engaging several Japanese capital ships and a destroyer squadron, Johnston was sunk with 187 dead, including Evans. Johnston's wreck was discovered on 30 October 2019 but was not properly identified until March 2021. Lying more than 20,000 feet (6,100 m) below the surface of the ocean, it was the deepest shipwreck ever surveyed until the 22 June 2022 discovery of USS Samuel B. Roberts, sunk during the same engagement.

USS Samuel B. Roberts (DE-413) was a John C. Butler-class destroyer escort of the United States Navy which served in World War II, the first of three U.S. Navy ships to bear the name.

Samuel B. Roberts was named after Coxswain Samuel Booker Roberts Jr., a Navy Cross recipient, who had been commended for voluntarily steering a Higgins boat towards enemy forces at Guadalcanal, in order to divert fire from evacuation efforts being undertaken by other friendly vessels. The ship was nicknamed the "Sammy B".

Ocean escort was a type of United States Navy warship. They were an evolution of the World War II destroyer escort types. The ocean escorts were intended as convoy escorts and were designed for mobilization production in wartime or low-cost mass production in peacetime. They were commissioned from 1954 through 1974, serving in the Cold War and the Vietnam War.

Pelican Island is an island located in Galveston County, Texas. It is part of the city of Galveston and is linked to Galveston Island by the Pelican Island causeway. The island is home to the Texas A&M University at Galveston as well as two museum ships—the destroyer escort USS Stewart (DE-238) and the submarine USS Cavalla (SS-244)—and Seawolf Park. Seawolf Parkway is the only street that runs across the island. The Intracoastal Waterway borders it to the north, separating Pelican Island from another island.

The south side of the island is home to multiple facilities, such as dry docks, and tugboat operators, that support the maritime industry in Galveston, and the Galveston Texas City Pilots who navigate ships through Galveston Bay.
