Mast modules for the 27,000 tonne Landing Helicopter Dock (LHD), fabricated and constructed at BAE Systems Henderson, facility are now completed and ready to be transported to Melbourne. The three mast modules weighing between 19 and 36 tonnes will form part of the superstructure of the LHDs and will house equipment including communication and combat systems, navigation and air traffic control radars and infrared search and track sensors. The mast modules will be loaded onto the heavy lift ship Henan Scan berthed at BAE Systems wharf at their Henderson load-out facility.
