North American A-36 Apache

"The North American A-36 Apache was the ground-attack/dive bomber version of
the North American P-51 Mustang, from which it could be distinguished
by the presence of rectangular, slatted dive brakes above and below the
wings. A total of 500 A-36 dive bombers served in North Africa, the
Mediterranean, Italy and the China-Burma-India theater during World War
II before being withdrawn from operational use in 1944."
"No funds were available for new fighter contracts in fiscal year 1942, but General
Oliver P. Echols and Fighter Project Officer
Benjamin S. Kelsey[url=https://en.wikipedia.org/wiki/North_American_A-36_Apache#cite_note-GML3-4][4][/url] wanted to ensure that the P-51 remained in production.

"Since appropriations were available for an attack aircraft, Echols specified modifications to the P-51 to turn it into a dive bomber. The
contract for 500 A-36A aircraft fitted with bomb racks, dive brakes, and
heavier-duty wing, was signed by Kelsey on 16 April 1942,
