Yes you heard that right the British had an A-10 of their own the British Aerospace P.101 Blitz sadly it was never put into production but was built from redesigned Jet Provost T.5 airframe with the jet exhaust removed and the canopy redesigned.

The single Rolls-Royce Viper Mark.201 Turbojet would be replaced with either two Rolls-Royce Viper Mk.600 turbojets generating 8000ibs of thrust or a single 5540ib thrust Rolls-Royce RB.401-35 Turbofan or US-made Garrett ATF3 Turbofan

The P.101 Blitz was to have a single 30mm GAU-13/A Rotary Gatling Gun firing an unknown number of rounds of PAU-14 Depleted Uranium Rounds like the rounds used in the A-10’s GAU-8/A Avenger.

Sadly I haven’t been able to find an image on google of this aircraft but there are diagrams in Chris Gibson’s Typhoon to Typhoon book on Royal Air Force Air Support Projects since 1945

From the pictures in the book this is a description of what I think would have been the most likely final design

A redesigned Jet Provost T.5 airframe with 30mm GAU-13/A in the nose, at the rear were a twin tail and two Rolls-Royce Viper 600 turbojets with four underwing hardpoints.

Side Note: I suspect the P.101 Blitz would’ve had its Rolls-Royce Viper mk.600s replaced with two Rolls-Royce RB.401-35 Turbofan giving 11,080ibs of thrust
