AW Dictor
There are a number of reasons for the hangar space needed for the RAF P8 fleet, the aircraft have to operate in a salt rich environment, spend far more time at low level in a high fatigue regime and the aircraft are packed with Avionic systems in the place that Ryanair has seats.
All of this requires far more mainanace per flight hour hence the requirement for what at first glance seemed to be a lot of hangar space for a small fleet.
