The nose docking was integrated into the mezzanine structure to provide access between open work area and the aircraft.

COX prepared the functional design brief and general arrangement drawings for the docking for a D&C Docking Tender and Contract.


The design and construction were successfully delivered during COVID Lockdowns and NSW/QLD Border shutdowns. Strategies were developed during the design stages with Northrop Grumman’s project manager and actioned during construction to ensure long lead time items were ordered early and local industries used to supply and install the trade works. The hangar remained in operation during the works and key works were carried out during 2-3 weeks periods when there was no aircraft in the Hangar.

The Hangar is operating more efficiently with state-of-the-art docking systems and workshops. Northrop Grumman were very satisfied with the end result.
