The United States Navy’s newest supercarrier has cleared a major hurdle after years of delays. The USS John F. Kennedy (CVN-79) successfully completed its sea trials on August 15, 2026, marking a critical step toward joining the fleet’s active inventory, according to an announcement from Newport News Shipbuilding, a division of Huntington Ingalls Industries.
Long Road to Completion
The Kennedy’s construction timeline stretches back more than a decade. The ship’s keel was laid down in July 2015, and the carrier has faced several delays that pushed back its entry into service. The sea trial process itself began on January 28, 2026, and lasted 6 months and 18 days before acceptance.

Sea trials brought together Navy personnel assigned to the ship alongside shipbuilders to conduct extensive testing at sea. Passing these trials moves the Kennedy closer to delivery, though the vessel still has a significant amount of work ahead before it can be handed over to the Navy.
What Comes Next
With sea trials complete, the Kennedy will now enter the Contractor Fitting Out phase. This stage involves inspections, inventory checks, and loading the carrier with equipment. It also includes several specialized programs such as high-value reviews, Navy total assessment visibility, outfitting requisition control, accounting systems, and sponsor-owned material programs.
The fitting out period typically takes around six months. After that, the ship will be delivered to the Navy, but it still won’t be ready for full operations. The Navy then conducts a post-shakedown availability, a period of 6 to 12 months where the carrier undergoes intensive testing to fix any deficiencies identified during its shakedown cruise. Improvements are made during this time as well.

Once the post-shakedown availability wraps up, the Kennedy will depart its construction yard for its homeport. That move signals the end of the ship’s construction period and marks its transition to active duty. The delivery date is currently expected to remain unchanged, with the carrier arriving for full service in March 2027.
All Navy vessels undergo post-shakedown availability, a practice in place since at least World War II. The Navy did deviate from this standard with its newest fast-attack nuclear submarine, the USS Massachusetts (SSN-709), but that exception hasn’t applied to carriers.
