With a 70 ft wingspan, pressurized cockpit, four 20 mm cannons, two Merlins, a top speed of 390 mph and a service ceiling of 45000ft, the Welkin was cutting edge for 1942. Kept in reserve to counter Germany if it attempted high altitude bombing of Britain , the Welkin could fly higher than any other British aircraft of the day. The threat never materialized but 67 were kept in reserve. This illustration shows the prototype testing the 250 gallon drop tanks.
The aircraft is 100% vector with the background a mix of vector and raster.
