The ceremony included ship sponsor Maureen Paparo, a Philadelphia native, who was joined by her spouse, Adm. Samuel Paparo, commander U.S. Indo-Pacific Command. Also, attending the ceremony was Chris Kastner, HII’s president and CEO, Brian Blanchette, Ingalls Shipbuilding president and key U.S. Navy officials.

As part of the ceremony, Ingalls Structural Welder Cory Dillon etched the sponsor’s initials into a ceremonial steel plate, a long-standing naval tradition symbolizing the ship’s official start of construction. The plate will remain permanently affixed to Philadelphia throughout its service life.
