The ship that became the first HMS Resolution was a 50-gun third-rate frigate built under the 1652 Programme for the navy of the Commonwealth of England by Sir Phineas Pett at Ratcliffe, and launched in 1654 under the name Tredagh (Tredagh is an alternative name for the Irish town of Drogheda, scene of the Siege of Drogheda, a Roundhead victory, during the English Civil War).
