Description

GarageImage AU-1.jpg


The AU-1 Corsair is a premium gift rank IV American attacker with a battle rating of 5.7 (AB/RB/SB). It was introduced during Update 1.97 "Viking Fury" as a reward for the "Space Race" event.

General info

Flight performance

The AU-1 has below-average flight performance. Although speed is good, manoeuvrability is lacking, as is climbing ability and high-altitude performance.

Usage in battles

Armament:

The AU-1's defining characteristic is its ability to carry incredible amounts of suspended armament--as much as a B-17 heavy bomber. In Air Realistic battles, the AU-1 can destroy two bases (bombing points), and in Ground Realistic battles, the plane has the potential to absolutely devastating against enemy ground forces. From carpet bombing, rocket barrages or precision drops, this plane can do it all.

Additionally, the four cannons provide very effective frontal armament (they're some of the best 20 mm cannons in the game) and the high ammunition count is a nice bonus, too. They wreak havoc on enemy aircraft, deal considerable damage to lightly armoured tanks and wheeled vehicles, and in Air realistic battles can destroy light pillboxes and light tanks.

Flight Performance:

But despite the AU-1's incredible ground-attack capabilities, it has very poor flight performance. It is often unresponsive, even without ordnance loaded, and with a full bomb loadout, the plane is about as manoeuvrable as a heavy bomber.

In Air Realistic battles, the AU-1 receives an attacker air-spawn. However, it climbs poorly and its engine is quite weak at high altitudes, so players will be unable to take full advantage of the air-spawn. Very often, teammates and enemy fighters will out-climb this aircraft. In a dogfight, the aircraft is heavy, sluggish, and generally outmatched.

As for speed, the aircraft is capable but less so than its counterparts. In low-altitude level flight, the AU-1 is around 40 kph slower than its cousin, the F4U-4B. In a high-speed dive, the elevator tends to compress making it more difficult to manoeuvre.

Recommended Play-styles:

Due to its poor flight capabilities, it is not recommended that the AU-1 be used in a fighter role. Instead, it may be used to destroy ground targets in Air RB or to destroy enemy ground forces in Ground RB. Remember that this aircraft, if left alone, can deal incredible damage with its bombs, rockets, and cannons. But, also keep in mind that enemy fighters and SPAA will not struggle to shoot it down.

Pros and cons

Pros:

  • Many load-out options provide flexibility for any battle situation
  • Strong ground-attack capability; armour plates are located in the underbelly of the plane to protect it from machine gun fire
  • Central bombs/tiny tims can be dropped/fired individually, wing bombs/HVARs dropped/fired in pairs
  • Can achieve missions for attackers while still receiving premium bonus (RP & SL)
  • Premium bonuses (344% RP, 360% SL as basic multipliers)
  • Low repair cost (2,720 SL basic max repair cost)
  • Good speed and energy retention below 1000m
  • Relatively easy to keep engine cool on 1st supercharger gear

Cons:

  • Poor elevator authority
  • Weak high-altitude performance
  • Less engine power than F4U-4B and power drops off quickly above sea level
  • Prone to engine overheating on 2nd supercharger gear (WEP above 2000m and 100% over 3000m)
  • Speed and manoeuvrability reduced compared to other F4U-4 fighters as it configured as an attacker
  • Poor maneuvering energy retention, even when unladen with ordnance

History

Main articleF4U Corsair History

The AU-1 stood out from the rest of the Corsair variants, as it was not designed as a fighter, but as a dedicated ground-attack aircraft. The F4U-6 was developed from the F4U-5 series, and as such had similar characteristics. It had the same metal skinned wing panels and blown cockpit design as the F4U-5 series. It was designed as a low altitude ground attack aircraft, and as such had a large number of modifications that other Corsairs did not receive.

The XFU-6 prototype, a modified F4U-5N, first flew on January 31, 1952. It had been renamed the XAU-1. Because the AU-1 was designed for low altitude ground attack, and not high altitude flying, the two-stage, variable-speed supercharger from the F4U-5 was replaced by the R2800-83W engine with a single-stage, manually controlled supercharger. This optimized the plane for low altitude flying. The R2800-83W did not require scoops on the cheeks. Ordinance options were also increased. The wing pylon count was ten, an increase from eight. There were five pylons on each wing. Each wing pylon could carry a 5 in HVAR rocket, a 100 lb bomb, or a 250 lb bomb. To carry 500 lb bombs on the wing pylons, only the outer, middle, and inner pylons could be used, for a total of six 500 lb bombs. The AU-1 also kept the three fuselage pylons, which could carry drop tanks, 1,000 lb bombs, and the centre pylon could hold up to a 2,000 lb bomb. Napalm bombs, Bat glide bombs, and Tiny Tim rockets could also be carried. The primary armament was the same four 20 mm cannons from the F4U-5, with 231 rounds for each gun. These cannons were modified for the AU-1 so that they could be fired in pairs or together. If fired in pairs, the firing time was increased by one hundred percent. Because the AU-1 would be flying low altitude missions, it would require extra armour to protect the pilot, engine, and fuel tank from ground fire. 25 armor pieces were added, and the oil coolers were moved from the nose to the wing roots, protecting them from ground fire towards the front of the plane. The AU-1 was an exceptional ground attack plane, but it had reduced speed and manoeuvrability compared to the other Corsair variants.

111 AU-1 aircraft were produced by Vought, and they were delivered between February 7 and October 10, 1952. They saw service with the US Navy and Marine Corps. They served with Marine squadrons during the second half of the Korean War, and the AU-1 was retired by the Navy reserves in 1956 and the Marine Corps in 1957. During the First Indochina War, 25 Marine AU-1s were given to France, and they were returned to the United States afterwards. Several AU-1s were given to the French Navy, and they served until 1964.

The AU-1 is part of the F4U family of aircraft. Its closest relative in-game is the F4U-4B. Unlike other members of the F4U Corsair family, the AU-1 is primarily a ground-attack aircraft.
