USS Nimitz enters post-maintenance trials
The US Navy’s aircraft carrier USS Nimitz (CVN 68) has entered sea trials after a 20-month Extended Planned Incremental Availability maintenance period at the Puget Sound Naval Shipyard, it was announced on 5 October.
Over 14 major upgrades were made to the ship during the period. The ship's C4I capability was modernised with numerous upgrades, and its integrated network was updated to the new Consolidated Afloat Network Enterprise Services system. Modifications were made to the ship's defences, adding an anti-torpedo defence system and two MK-38 anti-ship guns. The ship's second service turbine generator was rebuilt, while all four distilling units were overhauled.
Additionally, more than 100,000 square feet of flight deck non-skid was removed, and major repairs were made to the ship structure and jet blast deflectors.
Cmdr David Gast, Nimitz combat systems officer, said: ‘Teams from Combat Systems Department removed, refurbished and reinstalled over 150 antennas, saving over $3 million in contractor costs. We've updated every element of the ship's satellite communication, and information processing suites were upgraded or replaced.’
The Board of Inspection and Survey Material Inspections will review the work carried out in the coming months.
