The aircraft resembles what it would look like if the United Kingdom government chose the Grumman F9F Panther over, or together with the Hawker Seahawk as their primary naval (carrier based) attack fighter in the late 50-ies. This particular aircraft is in the colors of the Hurn-Airport based Airworks Services Limited Fleet Requirements Unit (FRU), testing aircraft for the Royal Navy.
The Panther's British counterpart, the Hawker Seahawk was tested by the same unit, for the same purpose. You need the payware Vertigo Studios F9F in order to use this repaint.
