Too bad turboprop engines arrived too late to see action

That's... creative.

The Allison T40 was plagued with problems, including oil leaks, runaway
props, and disintegrating gearboxes. Many promising aircraft designs were
doomed from the start because of down time caused by engine malfunction,
allowing competitors to get a leg up.

Had these been grafted to a B-25 airframe the performance would've been
spectacular, especially rate of climb. With three times the horsepower of
the original Wright R-2600s, it probably could have reached 480 mph, that
is, if it didn't fly apart (150 mph faster than its never-exceed speed).

Besides, a 60" Mk.4 "Fat Man' wouldn't have fit in a B-25.

Which was only moderately successful. The aircraft was not popular aboard
ship as it was so big and cumbersome that it complicated any other flight
operations the ship was required to conduct. One problem was that the wings
had to be folded one at a time by a crewman on top of the fuselage with a
portable hydraulic pump, a time-consuming process, so that the bomber could
be moved out of the way to allow other aircraft to land or take off. One
pilot reported that the AJ-1 was "a dream to fly and handled like a fighter"
when everything was working properly. The aircraft, however, was not very
reliable, possibly because it was rushed into production before all the bugs
could be worked out.

In a last-ditch effort to save the situation, NAA replaced the piston and
jet engines with two 5,000 hp. Allison T40-A-6 turboprops (the XA2J Super
Savage) The gremlin-plagued T40s kept it on the ground so much that its
competitor, the Douglas A-3 Skywarrior, which had far better performance,
won out.
