From 1980 to 1987 I was a 68M20: Aircraft Weapons Systems Repairer. I worked on AH-1S/F Cobras as well as AH-64s. While at Ft Hood, I worked on the old S marks with the M-134 Mini-guns. The M-134 is electrically driven with a rate of fire of 3000 and 6000 rpm. The motor is controlled by the 3-position trigger: off, 1st stop = 3000 rpm and 2nd stop = 6000 rpm. While that's the rate used by the Army back then, Dillon Aero's new M-134D uses a reduced rate of fire of 4000 rpm. That, as well as mechanical upgrades to the gun and de-linker has resulted in a weapon that is about 1000% more reliable than the ones I used to work on. The system used in the Cobras and -134 pods was a nightmare!!! If you had a jam in flight you turned around and RTB or landed and cussed for about 15-20 minutes while you broke things down to find the jam and fixed it. PIT@!!!
As for shooting the gun...gods!!! what fun!!! 6000 rpm with every 5th a tracer! Looked like the wraith of the gods was raining down on the target!!! It took about 3 days to get the S***-eating grin off our faces when we fired those guns! Only thing that was better was shooting the M-197 20mm Gattling on the newer S & F models. Only rated at 750 rpm but what a kick to the A/C when you shot that mudder! Never did get to shoot the wing podded 20mm used on the old -G models. That was a 2000 rpm Mo-Fo that had the unfortunate habit of blowing off the pilot's door before they modified the system. Our platoon leader at Ft Campbell was a CW-4 that used it in VN and he said that the A/C would slew to the right every time it was fired. Had to apply hard left to keep it on target. Said that they only had to make 1 or 2 passes before Charlie decided to find a safer place to be.
