HMS Warrior was a 40-gun steam-powered armoured frigate built for the Royal Navy in 1859–61. She was the name ship of the Warrior-class ironclads. Warrior and her sister ship were the first armour-plated, iron-hulledwarships, and were built in response to France's launching in 1859 of the first ocean-going ironclad warship, the wooden-hulled Gloire. Warrior conducted a publicity tour of Great Britain in 1863 and spent her active career with the Channel Squadron. Obsolescent following the 1871 launching of the mastless and more capable HMS Devastation, she was placed in reserve in 1875, and was "paid off" – that is, decommissioned – in 1883.
