I can never resist a good challenge so here is my entry, the HAe Maelstrom light fighter:
EDIT: I've finally found some time to finish my design to the current standard:
Created to meet a 1980 NATO design specification for a light fighter to replace the A-4 Skyhawk on many small anti-submarine carriers, the Maelstrom was designed to outperform the MiG-21 and Mirage and compete with any contemporary fighter it was likely to meet (although its primary adversary was expected to be maritime patrol aircraft). The aircraft was designed with ease of maintenance and ruggedness in mind to enable it to operate from austere airfields and HAe used many parts in common with the F/A-18 Hornet then entering service (such as the engine and radar for example) to limit potential strain on the NATO supply train during wartime.
Although the NATO specification was subsequently cancelled, HAe continued with production and the resulting HAe Maelstrom saw extensive use in not only the Recherche Armed Forces but also the wider Commonwealth, operating from Recherchean, Australian, Canadian, Indian and British carriers as well as in the air forces of Recherche, Australia, Canada, India, Malaysia, New Zealand, Papua New Guinea, Singapore, South Africa and Britain. The prototype was considered to be under-powered with the GE F404 and so after searching for a suitable more powerful engine, HAe settled on the Pratt & Whitney F100 which improved power greatly. This was the main production variant and saw improvements in acceleration, agility and range as a result, although it proved to be more maintenance intensive in service until the F100-220 came along.
