HMS Warrior (R31) was a Colossus-class light aircraft carrier which served in the Royal Canadian Navy from 1946 to 1948 (as HMCS Warrior). She was transferred to the Royal Canadian Navy, commissioned as HMCS Warrior and placed under the command of Captain Frank Houghton. She entered Halifax harbour on 31 March 1946, a week after leaving Portsmouth. She was escorted by the destroyer HMCS Micmac and the minesweeper HMCS Middlesex. The RCN experienced problems with the unheated equipment during operations in cold North Atlantic waters off eastern Canada during 1947. The RCN deemed her unfit for service and, rather than retrofit her with equipment heaters, made arrangements with the Royal Navy to trade her for a more suitable aircraft carrier of the Majestic class which became HMCS Magnificent (CVL 21) on commissioning.

From the Wikipedia description of HMCS Warrior:

Warrior was a Colossus-class light aircraft carrier that was 630 feet 0 inches (192.0 m) long between perpendiculars and 695 feet 0 inches (211.8 m) overall with a beam at the waterline of 80 feet 0 inches (24.4 m) and an overall width of 112 feet 6 inches (34.3 m). The ship had a mean draught of 23 feet 3 inches (7.1 m). Warrior had a standard displacement of 13,350 long tons (13,560 t) when built and a full load displacement of 18,300 long tons (18,600 t). The aircraft carrier had a flight deck 690 feet 0 inches (210.3 m) long that was 80 feet 0 inches (24.4 m) wide and was 39 feet 0 inches (11.9 m) above the water. The flight deck tapered to 45 feet (14 m) at the bow. For takeoffs, the flight deck was equipped with one BH 3 aircraft catapult capable of launching 16,000-pound (7,257 kg) aircraft at 66 knots (122 km/h). For landings, the ship was fitted with 10 arrestor wires capable of stopping a 15,000-pound (6,804 kg) aircraft, with two safety barriers rated at stopping a 15,000-pound aircraft at 40 knots (74 km/h). Warrior had two aircraft elevators located along the centreline of the ship that were 45 by 34 feet (13.7 by 10.4 m) and could handle aircraft up to 15,000 pounds on a 36-second cycle. The aircraft hangar was 275 by 52 feet (83.8 by 15.8 m) with a further 57 by 52 feet (17.4 by 15.8 m) section beyond the aft elevator, all with a clearance of 17 feet 6 inches (5.3 m). The hangar was divided into four sections by asbestos fire curtains. The hangar was fully enclosed and could only be entered by air locks and the lifts, due to the hazardous nature of aviation fuel and oil vapours. The vessel had stowage for 98,600 Imperial gallons (448,244 l; 118,414 US gal) of aviation fuel.

The ship was powered by steam created by four Admiralty 3-drum type boilers driving two Parsons geared turbines, each turning one shaft. The machinery was split into two spaces, each containing two boilers and one turbine, separated by 24-foot (7.3 m) spaces containing aviation fuel. The spaces were situated en echelon within the ship to prevent a single disabling torpedo strike. The engines were rated at 42,000 shaft horsepower (31,319 kW) and the vessel had a capacity for 3,196 long tons (3,247 t) of fuel oil, with an range of 8,300 nautical miles (15,372 km) at 20 knots (37 km/h). The ship’s maximum speed was 25 knots (46 km/h). There was no armour aboard the vessel save for mantlets around the torpedo storage area. There were no longitudinal bulkheads, but the transverse bulkheads were designed to allow the ship to survive two complete sections of the ship being flooded.

Warrior was designed to handle up to 42 aircraft. The aircraft carrier carried a wide range of ordnance for their aircraft from torpedoes, depth charges, bombs, 20 mm cannon ammunition and flares. For anti-aircraft defence, the aircraft carrier was initially armed with four twin-mounted and twenty single-mounted 40 mm Bofors guns. The original radar installation included the Type 79 and Type 281 long-range air search radars, the Type 293 and Type 277 fighter direction radar and the “YE” aircraft homing beacon. The ship had a maximum ship’s company of 1,300, which was reduced in peacetime.

After service with the RCN, Warrior was returned to the Royal Navy, and subsequently sold to Argentina, entering service as ARA Independencia until 1971 when she was struck from the Argentinian navy list and scrapped.
