The number one killer for us has been due to degraded SA, especially in a task saturated environment. Yet is amazes me that we have few technological advances in place to help with that (minus that wonderful robotic voice). We operate so close to the ground and rarely transit from NAVAID to NAVAID. For example something as simple as a moving map, not even to navigate with, would increase SA exponentially. Hell, my $200 phone has a moving map yet my $30 mil helo does not.
The way that the Navy Helo community (primarily CVW Sierra and Romeo types) is trying to put more missions on the plate will cause the need for change. Its only been a couple years at most that S & R have been deploying on a carrier together. There's a lot of new technology many are still unaware of in those platforms (ex: Link 16, M-197, UGR, etc) There are three Sierra squadrons (I know of) deploying with either the M-197 and/or the LAU 61 UGR within the next six months. Yes, we do use the grease pencil aiming system haha Though, they're only rumors now the current talk is two land based dets off the carrier..... GOPLAT defense and straits transit defense.
I believe when push comes to shove things will be noticed more.
