myself and 3 JGSDF pilots debated this quite a bit, we even have some flight profiles set in the sim suite. One of the pilots was a chief IP at ft. hood for 3 years, and also 15 years in the apache and testpilot for the japanese Apache program (US ARMY CW3)
His comment was simple... I need terrain. at altitude im dead. i can use the gun but only in a beam/flanking shot, but the apache gun cannot track and hit accurately...
I tried it in the sim as well it was pretty tough...
the LG hellfire cannot hit targets moving above 110 mph,
I know this for a fact when i designed the GA predator system.
The hellfire seeker is not designed for high angle boresights. it is set up to dive to a target that does not present a dynamic aspect point of reference.
2nd problem is Hellfires lack of manueverability.
A2A Sidewinder, even match,
first eyeballs/ first shot.
