Abstract: Rapidly reconfigurable palletized mission equipment mounting systems and methods employ a plurality of tracks or rails installed in an aircraft fuselage. Mission equipment is secured on a pallet. The pallet is a rapidly reconfigurable mission equipment mounting pallet body defining a plurality of orifices sized to accept releasable anchor hardware, positioned to align with the tracks or rails installed in the aircraft and readily releasable anchors disposed in the orifices and configured to rapidly mount to, and rapidly dismount from, the tracks or rails. The pallet with the mission package(s) secured thereto is transferred into the aircraft and mounted the pallet in the aircraft on the tracks or rails, via the readily releasable anchors, for rapidly dismounting from the tracks or rails.
