ANU Durazno (BCV-1948)

The Uruguyan Navy being so small, every ship in it had to be a multi-role vessel. With the end of World War Two the Uruguayan Navy went shopping. It new what it wanted. A battlecruiser/battleship that could be converted into a battle carrier. With guns forward and what would amount to an escort carrier aft. In the building yards of the US Navy they found what they were looking for. A Virginia class battleship.

Plans were made with the dockyard concerned to convert the battleship to a battle carrier. Adding that much superstructure required the removal of a lot of armour, normally fitted to a battleship, so that a 20 foot high hangar could be fitted. What made the ship perfect for conversion was the breadth of the ship at 106 feet. This gave plenty of room for storage of aircraft. The flightdeck was 482 feet long, as good as most escort carriers.

On completion in 1948 the ships air complement was 24 Avengers, 18 in the torpedo bomber configuration and 6 in the ASW configuration. 18 Hellcat fighters were carried, 12 as day fighters, and 6 configured for nightfighting. These aircraft lasted through to 1959 when they were replaced with 12 Fairey Gannets and 12 Sea Fury aircraft. The ship could have carried more but the ANU was short of funds. So why the change from US to British aircraft? The British were still producing slow prop aircraft that could be launched from the Durazno, while the US was building aircraft that could operate off their big Essex, Midway and Forrestal class carriers. During the 1960's two lots of 6 helicopters were added to the complement to give a total of 36 aircraft aboard. The Durazno was considered too short for jet aircraft during the 1950-70 period. The Gannets were replaced with 18 more helicopters as those became better and better for ASW duties. The ship retained the Sea Furies through to 1974 as the major strike aircraft.

1975 and the Durazno was taken in hand for a major refit in the UK shipyards to update the aviation facilities and electronic outfit. The old superstructure and masts were cut down and replaced with modern units to carry the new electronic warfare units and equipment. The 14" weapons were to be controlled by the MSR-3 director that was tied into the other radar units on the ship. The biggest addition was the fitting of a 'ski jump' so that the Durazno could operate the Harrier jump-jet aircraft. The other aircraft aboard were still the helicopters of the Sea King type for ASW duties.

During all of this period, the Durazno carried the same armament as it had been completed with. The investigations of upgrading the AA armament with missiles such as SeaCat and other point defence equipment, shocked the ANU with the price. Investment in command and control functions and aircraft operating facilities was considered more important. To provide some form of 'missile' defence the ANU bought half a dozen Stinger shoulder mounted units and kept the old armament aboard. At one stage when operating in the Persian gulf with the other Allied nations, it was found that the quad 40mm with their directors were very good at shredding the 'Zodiac' attack boats used by the insurgents against Allied Fleet units.

The Durazno was to operate in this guise through to 1995 by which time a new command ship / aircraft carrier was to have been sourced to replace it. Something like HMS Ocean would suit them very nicely.

The Sea King was the ASW aircraft of choice aboard the Durazno during its last period of service.
