decisions. The biggest debate, however, was over basic principles. At th… Endurance was 4500 miles at 24kts in six months out of dock condition.Under helm, turn trials revealed Eagle was easy to handle with a tactical diameter at 30kts and 35 degrees rudder of 847 yards with a 5.3 degree heel. Eventually, only Ark Royal and Audacious (renamed Eagle) would be completed.Constant ‘tinkering’ and alterations with the design during construction would end up producing a 36,970 ton (standard) displacement vessel of 803ft 9in overall, with an extreme breadth of 135ft and a mean draught of 32ft 9in.When laid down in 1942, the Audacious class was the largest aircraft carrier in the world.Audacious (later renamed Eagle) was laid down on October 24, 1942. rearming, it was clear that aircraft carriers were going to play a significant Instead it would remain at 1.5in – offering splinter protection to the vulnerable aircraft within.The armoured bulkheads and doors at the entrance to the lifts, while of upgraded design, also remained the 4.5in of the earlier ships.On the hangar floor was 2.5in armour plate, tapering to 1.5in.The traditional armoured citadel was designed to integrate with the protected hangar.

Gone were the deck 'cutaways' housing directors and anti-aircraft guns, making the traditional inline flight deck moreServicing the flight deck were two cranes of 25,000lb load. Both were expected to receive aircraft of 30,000lb at 75kts, or 20,000lb at 91kts, imposing a maximum deceleration of 2g.Eight arrester wires and three crash barriers were specified. This was a result of the loss of Ark Royal in 1941: Keeping the engine space trunking to the funnel as high as possible would reduce the chance of water rushing deep into the ship if damaged.High capacity ventilation fans were fitted to the closed hangar sides in order to allow about 18 aircraft to warm up their engines while waiting to be lifted to the flight deck for launch.But the size and shape of the Audacious class carrier lifts once again highlighted the problems first realised with Illustrious.They were outside the armoured portion of the flight deck. Here subdivision remained the only defence.While an under-hull protection system for magnetic mines and deep-running torpedoes had not yet been devised, the new carrier was given a 1in thick inner bottom connected to transverse and longitudinal bulkheads to limit the extent of flooding.The Royal Navy’s characteristic concern for the flammable and explosive characteristics of aviation fuel was again evident. The order for the fourth ship, Job Number J1722, was changed to a unit of the larger Malta (Gibraltar) class. This was judged to be at least 64 machines.Improved aircraft operability: Bigger lifts, more crew, more stores, more ammunition, more spares needed to be carried to accommodate deployments of more than a few days.Increased flight deck size: The bigger the flight deck, the more aircraft could be crowded on it for flying-off operations. Considerable space was sacrificed in order to keep this fuel safe.Audacious kept its avgas in three sets of cylindrical tanks, each sat inside flooded compartments. But, in the case of the Implacables, the error of limiting hangars to 14ft became apparent during their protracted construction.In 1940 war losses and the freshly obvious importance of carriers saw consideration of a repeat order for two more of the Implacable class.Improved flight deck armour: It was evident aircraft were now regularly hefting bombs greatly in excess of the 500lbs the 3in on Illustrious was optimised to resist. But growth during construction reduced this to 30.5kts. They were also capable of remaining functional up to 20 degrees of heel.Some 6600 rounds of 4.5in ammunition were carried split between fore and aft magazines. But underway replenishment was accepted as a necessary compromise.Continued tinkering with the design during construction after 1945 saw this rise to 165,000gall. after the end of the war with Japan – at which point the Board postponed further She was initially laid down on 24 October 1942 at Harland and Wolff shipyard in Belfast as one of four ships of the Audacious class. The cutaway shows HMS Ark Royal, completed to a more modified design than Eagle. The wider hull of Audacious, however, removed the ‘gully’ effect these gun sponson’s had on the flight deck space.Aircraft could now be ranged on either side of the aft lift between X and Y 4.5in batteries.Like Implacable, the turrets were flush with the flight deck to assist instead of impede aircraft operations. A 14,000lb plane could be catapulted at 85kts. Thank you! There was one mobile 20,000lb crane, two 15,000lb fork-lift tractors, as well as eight other tractors of varying types.Initial plans to provide two upgraded twin-track trolley-style accelerators were abandoned in 1943 in favour of solely using the US strop-based two-point, tail-down technique.It was specified that a 30,000lb aircraft should be able to be propelled into the air at a speed of 75 knots.

The Audacious-class aircraft carriers were a class of aircraft carriers proposed by the British government in the 1930s - 1940s and completed after the Second World War.The two ships built were heavily modified and diverged over their service lives. Requirements were for a ship capable of operating aircraft of 30,000lb instead of the 11,000lb as specified for Illustrious. At 15kts this was 802 yards. It was feared the tonnage and hull limitation meant the new design would retain Implacable’s 14ft hangars, though it was discovered some extra height could be recovered through reducing the depth of structural beams.The revised group would be given the class-name IrresistibleOn November 30, 1941, the Irresistible programme was cancelled.Wartime shortages of materials (in particular armour) and a change of priorities (towards constructing anti-submarine sloops and frigates) had already resulted in delays in the construction of the two ships of the Implacable class.Further war experience had dictated the need for much greater redesign than a simple revision of the Implacable form.HMS Illustrious had – as intended – proved remarkably resilient against the pounding she had taken from Stukas off Malta.
