In 1999 Sir Michael Boyce, First Sea Lord of the Royal Navy, visited the Puerto Belgrano naval base and paid tribute to those who died.[3] In 2003 a search team aboard Seacor Lenga, crewed by Argentine and British veterans, was sponsored by National Geographic to find the sunken cruiser but failed to locate it.[citation needed] The area where General Belgrano sank, though not found, is classified as a war grave under Argentine Congress law 25.546.[4][5]
