Tristar is the submerged Lockheed L-1011 aircraft that anchors Aqaba’s Underwater Military Museum as a large artificial-reef wreck. The airframe rests on a sandy bottom with the fuselage, wings, and tail providing clear exterior swim-arounds and strong photo angles. This is a boat-only wreck dive suited to trained divers who can manage overhead risk and limited interior access. The structure was adapted for diver access and is used to draw pressure off natural reefs while building new habitat around the aircraft.
