The HMS Endeavour was the immense flagship of Lord Cutler Beckett of the East India Trading Company. It was the ship that led Beckett's armada during the War Against Piracy. Beckett maintained an expansive cabin on the Endeavour, which contained a large globe to complement the map of the world that was painted in his office in Port Royal. It was sunk in the barrage by the Black Pearl and the Flying Dutchman.
The Endeavour also appears in the Disney/Square Enix video game, Kingdom Hearts III, where events in the world based off of Pirates of the Caribbean play based off of At World's End. After Sora, Donald, Goofy, and Jack take Elizabeth off the Flying Dutchman before it sinks into Calypso's maelstrom with a mortally-wounded Will on board, Beckett and the Endeavour move to attack the Black Pearl, only for the Dutchman to resurface with Will as the new captain. As the Pearl and Dutchman move to flank the Endeavour in a double broadside attack, Beckett is stunned with shock at having been outmaneuvered, and is unable to give commands as the Pearl and Dutchman open fire. The Royal Marines serving under Beckett and the East India Trading Company abandon ship when they realize the Endeavour is doomed, and Beckett is killed when the powder magazines ignite and detonate, destroying the rest of the ship and leaving it to sink to a watery grave. With the loss of both Beckett and the Endeavour, the Royal Navy armada under Beckett is left with no choice but to withdraw in defeat, leaving the Brethren Court victorious.
