The Boomerang Mk II (Great Britain) is a premium British fighter. It has been in the game since the start of the Open Beta Test prior to Update 1.27 as a premium vehicle purchasable in-game with Golden Eagles, but was removed from in-game sale after the 9th Anniversary Sale. Buying the plane required the purchase of the Boomerang Mk I to unlock. It has been made available for Golden Eagles during the 2022, 2023, and 2024 "Australia Day" mini-events. This variant of the Boomerang represents a version which was designed and manufactured in Australia.

Compared to the first variant, the Boomerang Mk II has the added capability of carrying bombs for better ground attack capabilities. The plane can out-turn almost any plane, save for Japanese planes. The Boomerang Mk II is lacking in the amount of ammo for the cannons. Some good tactics are to stay low to the ground, and like with all planes, keep a good eye on where each plane is, in AB stay low and "mow the yard" anything that comes close, just prepare to turn-fight them, and take them out, be cautious with your cannon ammo, as those are your only "heavy" hitting guns. Downsides to the Boomerang is that it is rather slow when compared to other aircraft of its tier. Keep in mind that low altitude fighting is its bread and butter and can easily out-turn just about everything in arcade battles and in realistic battles.
