By 1944, Westinghouse was working on three derivatives of its first axial engine, the 19A (19 inch diameter). The 19A's direct descendant, the 19XB, became the J30. The J30 was first tested under a B-26 Marauder and powered the McDonnell FH-1 Phantom.
Of the 261 engines produced, Pratt & Whitney built half.
