Having spent a bit of time in research mode with the red book, you may be interested to know that of 26 military airfields with precision approach facilities, there are 58 PAR equipped runways against only 25 with ILS. Only 3 airfileds have dual ILS's; Brize Norton, Linton On Ouse and Llanbedr. There are 5 airfileds with PAR only; St Athan, Culdrose, Topcliffe, Wittering and Yeovilton.
So which bill do you want to pick up:
a. Trash this new piece of pooh and either repair (if possible) or replace with another PAR.
OR
b. Buy 33 new ILS installations and pay the bill to sort out the FMI issue (if possible) on the aircraft fleet.
