Kye and Elena Osti (not pictured) of Seal Beach are proud of their daughter named “Liberty” (seen here with USS Dewey crew members). The Ostis witnessed the Navy ship, which cost $1 billion-plus, commissioned on Saturday at the Seal Beach Naval Weapons Station. “Our daughter asked us why that big ship was in our backyard. We promised her on Saturday she would find out and attend the event,” her dad said.
