The Boomerang has a severe tendency to catch fire when shot, due to its large, centrally-positioned fuel tanks.

The Boomerang Mk I (Great Britain) is armed with:

• 4 x 7.7 mm Browning machine gun, wing-mounted (1,000 rpg = 4,000 total)

Usage in battles

The Mk I Boomerang is not very fast for a fighter for its BR at roughly 460 KPH at sea level with WEP, and it loses power very quickly starting at an altitude of 4000 meters. From this, it would be thought that the Boomerang isn't much of a capable fighter, as most of its opponents are capable of reaching 500 KPH at any altitude, yet the Boomerang possesses great manoeuvrability.

Therefore, the Boomerang is best played in a turn-fighting role, almost as a British A6M, as even though the statistics claim a rather average turn time, at low altitude it is a turning-monster, capable of competing with even some Japanese fighters.

The armament of the Boomerang is also quite acceptable for its rank, with 2 20mm Hispanos and 4 7.7 Browning machine guns, which also emphasises its turn-fighting role. However, Boom and Zoom tactics are also possible with the Boomerang, as its decent rip speed, lack of rudder-stiffness at high speed and good rate of climb allows it to make decent passes on any enemies unfortunate enough to be underneath it.

It most also be noted that the massive fuel tank behind the pilot is very prone to catching fire if hit, so when being attacked it is suggested to roll away, as the Boomerang also possesses a good roll rate.

Pros and cons

Pros:

• Tight turn speed and Roll ability at low altitude
• A large amount of secondary machine gun ammunition (4,000 Rounds)
• Large choice of ammo belts for both the cannons and machine guns
• Decent rate of climb (14.9m/s)

Cons:

• Poor performance at higher altitude, notably above 4000 meters
• Cannons only have 60 rounds in each gun
• Average speed for a Fighter Aircraft (even for Rank II)
• Overheats very quickly when using WEP

In-game description

The CAC Boomerang was an Australian single-seat, single-engine fighter of mixed wood and aluminium construction.

The Japanese attack on Pearl Harbour on December 7, 1941 and subsequent events in the Pacific theatre of operations showed how unready Australia was for war. The country had fewer than two hundred military aircraft, most of them obsolete. At that time, the Commonwealth Aircraft Corporation (CAC) only produced a trainer, the CAC Wirraway (a licensed version of the American NA-33). The License Agreement provided for modifications, so, in order to have fighter aircraft as soon as possible, the CAC decided to use the trainer as a basis for a new fighter.

The CA-12 (later called the Boomerang Mk.I) was created, the first domestically produced fighter to ever roll off Australian assembly lines. The CA-12 borrowed the Wirraway's landing gear, tail, and wing design and was powered by a liscene built American Pratt and Whitney Twin Wasp engine, rated at 1200 hp. The aircraft was armed with two 20mm Hispano cannon and four 0.303 inch Browning machine guns and could carry four 9kg smoke bombs to mark targets, one 227kg bomb, or a 265 litre external fuel tank.

The CA-12 had high durability, good armament, and excellent handling characteristics at low level, although this performance deteriorated at height and the fighter's top speed was not at all competitive.

Mass production began in July 1942 and 105 Boomerang Mk I fighters were produced.
