The E-3s do have ground power and air con units with them with ZH101 and ZH106 in Echo dispersal at the southern end of the runway, while ZH102 was parked in the Sentry dispersal/compound outside of the main hangar.
ZH105 has been stood out as a hulk for many years on Delta dispersal and the blue notice adjacent to the crew entry door reads 'WEST - Waddington Emergency Synthetic Trainer'
It was unfortunately a grey day but here's just a few shots of how I want to remember them.

ZJ692 and ZJ691 in the background















E-3 ZH107 in 54 Sqdn's 100th Anniversary fin marks is parked on Charlie minus dome with also Sentinel ZJ693 parked behind.

This is the future with just arrived Sky Guardian UAV parked in a fenced compound adjacent to the RC135.
