You'll find that most tactical aircraft are not equiped with ILS ( think civilian) suites. The T-45C has a great ILS that can be used at civlian fields, even sweeter when you have the needles in your hud and can be 'outside' the cockpit the whole way down the chute. The Prowler has something that is supposed to be an ILS. I say supposed to be because it is the most ridiculous piece of equipment I have ever seen.
Most tactical (carrier based) are equipped with a system called ACLS. It is and ILS to the back of the boat. It can be 'coupled' to work in the Mode 1 stage, set that up with APC (auto-throttles) and you have the aircraft flying itself into the wires, you can be completely hands off. The Prowler can not be flown hands off all the way down, problems with the location of the receiver, however the Hornet can actually be flown all the way down on auto-throttles - or so I believe, anyone who knows definitively please add on.
