The Harrier was introduced into military service in the seventies, and has seen many significant changes over its life as technology improves. This has particularly been the case in the area of avionics.

However, the methods of maintenance have remained unchanged. Because of the difficulty in moving the components during maintenance, the RAF Future Integrated Support Team (FIST) has searched for a more efficient method of handling their aircraft. They focused on enabling the empty fuselage to be moved between stages during a 6-stage overhaul and rebuild process.

During the first and second quarters of 2003, a total of six large Solving Movers were built to RAF's specifications, to enable a complete Harrier to be loaded, jacked, dismantled and then moved in stages through the hangar. At the final stage the aircraft is wheeled off the Movers, fuelled and made ready to fly.

The leader of Harrier On-base FIST, Wing Commander Keith Cocksey, is very pleased with the Solving installation and says that it has "revolutionised the Harrier maintenance program" and also "achieved considerable savings in cost and downtime".
