The free event at USS Iowa located at 250 South Harbor Boulevard in San Pedro is aimed at honoring Southern California veterans and their families.
The celebration starts at 1 p.m. in front of the retired battleship and will feature free food, a children's play zone, live music, and resource booths. Veterans can also receive free passes to tour the USS IOWA Saturday through Monday.
"The event will be an unprecedented celebration with plenty of activities for the entire family as well as an opportunity to see and experience our beautiful and revitalized L.A. Waterfront," said Councilman Joe Buscaino, whose 15th District includes the port.
