Here's a couple fun facts. NAS Pt. Mugu never had an ILS until the Reagan years. One was installed for AF1. The ID? IRRG. Commonly known as the Ronald Reagan Glideslope.
And a VORTAC was installed on the ranch with a big landing pad for the helicopters. The Marines had a couple approaches designed for the facility.
The Navy isn't big on ILS for some reason, moreso seeming to enjoy TACAN or PAR. Granted, many of their fighters weren't even ILS capable, but whereas ASR/PAR is going away in the AF, the USN/MC loves it; and due to their ops, thats understandable.
