The US Navy's Nimitz-class aircraft carrier, USS Nimitz (CVN 68), has successfully completed sea trials, marking the completion of a 20-month extended planned incremental availability.

The six-day long sea trials were carried out to assess the ship's readiness by evaluating the crew's performance.

The operability of USS Nimitz's equipment and upgrades was also tested by conducting various system checks and drills.

"We got the opportunity to deep clean all the hangar bays after lighting off the AFFF."

The evaluations included the execution of high-speed turns, an activation of the ship's countermeasure washdown and aqueous film forming foam (AFFF) systems; sea and anchor, and precision anchoring exercises; testing of the ship's self-defense weapons; and man overboard drills.

US Navy Seaman Tyven Mcelhinny said: "Sea trials, for us, is a lot like a normal underway cleaning and maintaining the hangar bays.

"We got the opportunity to deep clean all the hangar bays after lighting off the AFFF. It was something I have never gotten to do, and it was actually really fun."

The ship's MK-38 25mm machine gun, MK-15 Phalanx Close-In Weapons System, and .50-calibre machine guns were also tested.

USS Nimitz will also undergo a series of inspections and multi-ship exercises as a part of a work-up cycle that will test the ship's proficiency and capabilities in preparation for her upcoming 2017 deployment.

The ship will be assigned to Carrier Strike Group 11 and Carrier Air Wing 11 for conducting flight operations and working on flight deck certification upon returning to sea.
