Project Description
The Joint Base Pearl Harbor-Hickam (JBPHH) was originally established in 1899 as Pearl Harbor with the addition of Hickam Field in 1938. In 2010 the two bases were combined forming the Joint Base Pearl Harbor Hickam. JBPHH provides berthing and shoreside support facilities for the Navy in addition to U.S. Pacific Command (USPACOM) and Commander, Pacific Air Force (PACAF).
