[:D]I remeber reading about an SBD that flew alongside a Kate and the gunners were shooting one another[:D] the result was preatty clear from the beggining 2x 12.7mm vs 1x 7.7 and no armor[:D]
Who had the 12.7mm? The only 12.7mm (aka .50 calibers) on the SBD were the cowling mounted ones the pilot fired. The SBD-3 and earlier were delivered from the factory with a single .30 caliber (7.9mm) in the rear. Between Coral Sea and Midway all carrier borne SBDs were modified in the field to have a pair of .30s in the rear. The SBD-4, 5, and 6 came with the dual .30s factory standard.
It took an incredibly big and strong guy to hold a pair of hand held .50s on the target. Even a single hand held .50 was too much for many gunners. Waist gunners were usually bigger and stronger than most of the rest of the crew on US heavy and medium bombers.
My father was a combat photographer attached to different bomber units. He had to qualify at every position on the plane so he could take over for a wounded gunner. He said the turret guns were no problem, but when he tried firing a hand held .50 from the waist position on a B-17, he fired a short burst at the target and the gun barrel slammed into the upper corner of the window.
He was a crack shot too. He qualified as expert with most single shot infantry weapons in basic. Someone warned him not to let anyone know about that or he might get transferred from the Signal Corps into the infantry as a sniper. The kick from a .50 startled him.
The only installation of paired, hand held .50s I know about were in the waist positions on the YB-40, which was an escort version of the B-17 bristling with fire power. The YB-40 proved to slow to keep up with the bombers on the return trip, so the project was canceled. I believe they combed the 8th AF for the biggest and strongest gunners for the waist positions on the YB-40s.
