Beep! Beep! Once again, the "Kick Merlin whilst it is down" bus is just about to leave.......
.......ALL ABOARD!
No, it hasn't got VOR/ILS, DME or ADF. But then again, we don't plan on operating in airways, or doing civilian IFR flying.
It has got a very good IRU/GPS, backed up by AHRS/DVS, which is other RN a/c's primary nav.
Your point?
