Veinticinco De Mayo (HMS Colossus class) light strike/ASW aircraft carrier

Displacement: 19,900 tons full load
Dimensions: 630 x 80 x 24.5 feet/192 x 24.4 x 7.5 meters
Extreme Dimensions: 695 x 133.4 x 24.4 feet/211 x 40.6 x 7.5 meters
Propulsion: Steam turbines, 4 boilers, 2 shafts, 40,000 shp, 24 knots

Armor: none
Armament: 12 40 mm AA
Aircraft: 21

Concept/Program: An ex-Dutch, ex-RN light fleet carrier purchased as a replacement for Independencia, which was obsolete by the late 1960's. This ship was originally a sister to HMS Warrior (later to become Independencia), but had been extensively upgraded.

Design: Had been refitted with an angled deck and extensive modernizations in Dutch service. Received new turbines during pre-transfer overhaul.

Operational: Initially operated combined ASW and strike air wing. The ship was in deteriorated condition by the 1980's, and played no major role in the Falklands war.

Departure from Service/Disposal: Inoperable due to poor condition by 1985. She was scheduled for re-engining and modernization, and the her old engines were removed in preparation for reconstruction, but the work was never carried out. Her hulk remained in nominal reserve until 1997, when it was announced that she would be scrapped.
