US Navy shipyard Puget Sound Naval Shipyard & Intermediate Maintenance Facility (PSNS & IMF) has completed the massive overhaul of USS Nimitz (CVN 68) aircraft carrier.

The latest development is PSNS & IMF’s seventh consecutive early or on-time completion of aircraft carrier availability.

Nimitz’s docking planned incremental availability (DPIA) started on 1 March last year and ended four days ahead of schedule.

PSNS & IMF commander Howard Markle said: “Completing this challenging and intricately complex task on time is an incredible feat all on its own. Doing it for the seventh time in a row, that’s exceeding all expectations, and it speaks volumes about the professionalism and dedication of our entire shipyard team.”

Prior to the Nimitz availability, PSNS & IMF and its Japan and San Diego detachments completed six carriers on time or early.

In December 2016, USS Theodore Roosevelt (CVN 71) underwent planned incremental availability that was finished on schedule in San Diego.

USS Ronald Reagan (CVN 76) had restricted availability and that was finalised one day early in Japan in May 2017. USS John C Stennis (CVN 74) underwent incremental availability and finished five days early in Bremerton in August 2017.

Last year, USS Ronald Reagan opted for restricted availability that was completed on time in Japan in May. Following this, USS Theodore Roosevelt planned incremental availability, which was completed 25 days early in San Diego in December.

Last month, USS Ronald Reagan selected restricted availability and work was completed on time in Japan.

Nimitz is the oldest carrier in its class. Its DPIA started with a plan of upgrades and renovations to steering components, hull preservation, combat systems equipment, aircraft elevator doors and berthing areas of the ship.
