You may be right about the UH-1N/Y. I don't fly it so I couldn't tell ya. But having seen the M240 and the GAU21, they aren't going to be very effective. Maybe the GAU, but it takes up so much damn room in the cabin, it is a mission package hog, and often times its really cool for the whole "CHUG CHUG JAM" of its effective life cycle.
But I don't know. I could be wrong. You tell me about my airframe. I'm sure you know better than all those folks who I've heard from about it from our deputy commodore up to CNAF.
I'm not telling you about your airframe. I'm just arguing that strapping another piece of equipment on an aircraft with no ordnance to train with isn't going to magically solve your problem. I MIGHT know a thing or two about training, and managing a squadron's training program.
It's amazing that the M240 and GAU-21 are so severly limited against a $5K "floating rust bucket". Funny. That's the same weapons that are strapped aboard a UH-1N/Y Huey for CAS missions (occasionally the GAU-17). And your comment about "CHUG CHUG JAM" = proves my point about training. Two words: Headspace & Timing. The GAU-21 is mechanically IDENTICAL to the M2 that the grunts use and the XM-218 that those of us in the assault support world use. It's been in service since 1933 and is ridiculously reliable. Provided the crew is trained.
It's the same lack of training that leads to negligent discharges of crew served weapons across the Elizabeth River in Norfolk. I don't think I'll live to see the fundamental shift in Navy mindset that would lead to an increased NCEA. So go ahead - blow your wad on a weapons system that looks cool, makes you feel like a bad ass, and shoot it twice in your career because of the limited NCEA. Then start saying that it's not the right system for the mission. OR change the mindset, spend the money on a realistic NCEA, get your crew proficient (proficiency = I've seen guys put first round center mass, on target and 75% of rounds on target), and all of a sudden your shitty crew served weapons will be probably much more lethal, and much more effective than you think.
