Statement of Significance (as of designation - May 28, 1987):
Pago Pago became the largest Marine Corps installation in the Pacific as Marines were rushed there to strengthen its defenses following the Japanese attack on Pearl Harbor. Samoa was a vital link in the route from U.S. to Australia and New Zealand, and there was considerable evidence that the Japanese were preparing to seize the Samoan Islands. Even when invasion was no longer a threat, after the Battle of Midway, the site played an important role as a Marine Corps advanced training center in jungle warfare and as a staging area for battles in the South Pacific. Blunts Point Battery is a rare example of a World War II coastal gun that remains in situ in the Pacific today.

The gun emplacements have been cleared of standing water and the drainage system cleaned. The guns have been cleaned, primed, and painted. The access steps have been repaired and the settlement has been corrected.
