Ship project history: The design of 13200t light aircraft carrier was ready in 1942. Special attention was given to construction simplicity and cheapness: such ships were supposed to build in a large batch and in the short time. As a whole Colossus has been constructed rather rational. Protection was not provided by the design, except for the steel 10mm plating covering aviation magazines.

Hull was designed on merchant shipbuilding norms, without special underwater protection, however ships had rational sectioning into compartments and stored unsinkability at torpedo hit into main transverse bulkheads area. Damage tolerance raise was promoted and by arrangement of machinery en echelon, placed in 4 compartments (2 engine and 2 boiler rooms).

Pioneer and Perseus were completed as aircraft maintenance ships. 

Protection: There were mantlets around aircraft torpedoes warheads rooms only. Their thickness was 10mm. Longitudinal watertight bulkheads covered the machinery.

Modernizations: mid-1945: Colossus: - 11 x 2 - 20/70, 10 x 1 - 20/70; + 19 x 1 - 40/56 Bofors Mk I/III

1/1946, Vengeance: 12 x 1 - 40/60 Mk III, 6 x 4 - 40/39 Mk VII, 37 aircraft, type 79B, type 281B, 6x type 282 radars, type 144 sonar

1/1946, Ocean: 28 x 1 - 40/60 Mk III, 6 x 4 - 40/39 Mk VII, 37 aircraft, 6x type 282, type 293, SM-1 radars, type 144 sonar

early 1950s, all survived: - type 79B, 281B radars; + type 277, type 293 radars.

9/1953, Warrior: enlarged bridge, lattice foremast. - 6 x 4 - 40/39, 6x type 282 radars; + 4 x 2 - 40/60 Mk 5, 1 x 1 - 40/60 Mk 3, 4x type 262 radars

8/1956, Warrior: partial angle deck, new arrester gear and catapult (9.1t plane was launched at 110km/h). Full displacement was 19600t, max speed: 23kts.

Fate Note: Warrior used as HQ ship for nuclear test in 1957. Triumph was converted to repair ship in 12/1957 - 1/1965 and stricken in 1980. Perseus and Pioneer were completed as aircraft maintenance ships (displacement standard: 16265 t, 211.7x24.5x7m, 4 x 4 - 40/39 2pdr QF Mk VIII, 2 x 1 - 20/70 Oerlikon Mk II/IV). Oerlikons were replaced by 2 single Bofors in 1946 - 1947. Both ships were reclassified to ferry carriers in 1953. Pioneer was sold for BU in 1954, Perseus was scrapped in 1957.
