This date appears to refer to the keel-laying / formal start-of-construction milestone for USS John F. Kennedy (CVN-79). That milestone did not occur in July 2015.

• Huntington Ingalls Industries' Newport News Shipbuilding — the shipbuilder — states in its August 22, 2015 release that it "today celebrated the keel laying" of John F. Kennedy (CVN 79).
• A U.S. Department of Defense release for the same event says the keel-laying ceremony for CVN-79 was scheduled for Saturday, August 22, 2015.

So the article's July 2015 date is incorrect for this milestone; the supported date is August 22, 2015.

The article places 23 March 2007 in the infobox field for "Retirada del servei" (removed from service / taken out of service). Official Navy records do not use that as the ship's actual removal-from-service date.

What the evidence shows:

• A 2025 official U.S. Navy/NAVSEA news release says CV-67 was "removed from service on August 1, 2007" after more than 39 years.
• The USS John F. Kennedy Aircraft Carrier Project history page explains the distinction directly: the ship's decommissioning ceremony was held on March 23, 2007, but the official decommissioning date was August 1, 2007.
• NAVSEA's historical evaluation for the ship also lists Inactivated 1 August 2007 / Decommissioned 1 August 2007, and explicitly marks a brochure's "Decommissioned March 23, 2007" wording as [sic].

So if the field is meant to show when the ship was retired/removed from service, 23 March 2007 is incorrect; that was the ceremony date, while the official service-end date was 1 August 2007.
