In 1956, the British Air Ministry cancelled production of the Hawker Sea Hawk in favour of newer aircraft. At this time, the Federal Republic of Germany were attempting to increase their naval aircraft inventory both looking for a daytime fighter-bomber and also an all-weather version. After comparing aircraft produced by other countries, the Bundesmarine concluded that the Hawker Sea Hawk fit their requirements and ordered 32 of each variant, the Mk.100, and Mk.101 with an underwing search radar pod.

Introduced as a premium pack in Update 1.87 "Locked On", the Sea Hawk Mk.100 is a mighty ground attacker, but also a capable air-to-air fighter. Though not as fast and sleek as other conventional fighters, in the hands of the right pilot, this aircraft can be critical to turning the tide in a match. Though hindered by the straight wings and Rolls-Royce Nene engine, compared to other contemporary aircraft, especially the swept-wing MiGs, the Mk.100 can hold its own in air combat. Though attempting to dogfight with rockets and bombs suspended from the aircraft is unwise, going for the more streamlined approach of just adding two AIM-9B Sidewinder missiles will bring the Mk.100 into contender status. Care is a must when firing a Sidewinder as there is potential for it to latch its targeting system onto friendly aircraft or even the sun. The four autocannons can make short work of other fighters and even bombers when targeting critical components such as engines, cockpit and fuel tanks.

The Sea Hawk Mk.100 was removed from the store after the 2021 May sale. It has since been made available for purchase in-game with Golden Eagles occasionally for specific German events like the 2021, 2022, and 2023 "German Unity Day" mini-events.
