Project FOLIO RAVELIN is an active Laundry project tasked with creating a warded, defended shelter to serve as an active command centre for the armed forces through the initial phases of a NIGHTMARE event.1 The RAVELIN committee are working closely with BUCKLER to determine what sort of defences will be incorporated into such a facility.
In fact, RAVELIN don't plan to construct such a facility from scratch, but rather update or upgrade existing hardened facilities for use in an OCCWAR crisis situation. RAVELIN staff have conducted surveys of candidate facilities at RAF_Boulmer(Northumberland), RAF_High_Wycombe(Buckinghamshire), the Permanent_Joint_Headquarters at Northwood (suburban London), and the Pindar bunker beneath Whitehall in central London.
