IMOP, based on some experience in NATO AWACS management, the NATO aircraft of NAEW&C were always very well serviced (some would say over-serviced) but also upgraded and continue to be so. RAF E3s are not so well placed, I hope they get back in the air very soon, because contrary to the naysayers, the platform is not a 'one trick pony' it could still be made much more versatile and capable.
