OK, this is an aircraft which was specifically designed as a high performance fighter & ground attack aircraft in the 1940s, but which although flying before the end of WW2, never saw any action.
The aircraft was faster & more heavily armed than anything comparable then in service, but failed very badly in regards to one of its primary requirments - there were several versions to fix this shortcoming, the last one being the only one that did. unfortunatley by the time this craft was truly fit for purpose, it was to late for its original requirment.
Over 300 of this plane were built & served, although never quite in the role they were designed for.
