The Mosquito B Mk XVI was a dedicated bomber variant of the de Havilland Mosquito, first conceived in April 1943. The Mk XVI was an improvement over the original bomber variant of the Mosquito, the Mk IV, with the main differences being a pressurised cabin, a two-stage supercharger, and an expanded bomb bay to carry the 4,000 lb "Cookie" bomb. In total, 245 of the Mk XVI were built, including the Mk XX subvariant produced in Canada, and they served extensively until the end of the war.

The Mosquito B Mk XVI was introduced in Update 2.51 "Spearhead". This variant of the Mosquito was designed for one purpose only: to deliver a heavy payload. The Mk XVI is capable of carrying a variety of payloads, including the massive "Cookie" bomb. This, along with the plane’s high speed, allows the Mosquito to perform close air support with great precision, as well as bomb bases with relative ease. However, aside from bombs and rockets, the Mk XVI lacks any guns to defend itself. This effectively leaves the Mosquito helpless against any aircraft capable of catching up to it.
