The APG-13B radar mounted in the B25 H saw limited action in the Pacific and China in 45. It's operable range was 5100-300 yards. It was only usable over water and not land due to ground interference. Mostly it was used to attack small light shipping that a single 75mm round would sink. By this time there was a scarcity of steamers and larger ships. The 75mm round from the B25 was not found to be effective at destroying heavier vessels, and ranges to successfully attack ground positions with visual aiming left the planes vulnerable to defensive fire.
One of the few Marine units that used the NAVY version with 75mm would fly to an enemy base at 2000ft. At about 8000yds out drop to 1500ft to pick up speed. From 6000yds they would begin firing the 75mm none stop as they closed on the installation visually sighting for ack and other positions. Once over the base dropping any bombs and using their 50 cal to strafe on the way out.
In our game this would effectively be an aimbot for the 75mm because it would remove the need to guess what your range to the target was. Still if Hitech made it useless when pointing at land. The 5 inch gunners would still slaughter the B25 because dispersion from the 75mm out side of 3000 is horrible coupled with accounting for the speed of the fleet.
