Marine Corps Asia Pacific Realignment:

DOD Should Resolve Capability Deficiencies and Infrastructure Risks and Revise Cost Estimates
GAO-17-415: Published: Apr 5, 2017. Publicly Released: Apr 5, 2017.


Reduction in Runway Length at the Futenma Replacement Facility

DOD has not fully resolved the capability deficiency of the planned runway at Camp Schwab, which will replace the 9,000-foot runway at Marine Corps Air Station Futenma but will be shorter. Mission operations at Marine Corps Air Station Futenma support operations involving a variety of fixed-wing, rotary-wing, and tilt-rotor aircraft. Marine Corps Air Station Futenma also supports the use of a runway if needed for a United Nations contingency, such as disaster response, for which U.S. Forces–Japan is a key partner. The proposed runway at Camp Schwab will not adequately support these same mission requirements, according to Marine Corps officials. Instead, there will be two 5,900-foot V-shaped runways that, according to Marine Corps officials, will be too short for certain aircraft. As we reported in March 1998 and is still the case based on our discussions with Marine Corps officials, the loss of Marine Corps Air Station Futenma's runway equates to the loss of an emergency landing strip for fixed-wing aircraft in the area and the loss of the United Nations use of a runway. According to an official from the Office of the Under Secretary of Defense for Policy, the office has not yet developed a plan for other alternate runways in Okinawa because it is not a priority. Although it does not yet have a plan for other alternate runways in Okinawa, DOD did take an initial step in April 2014 when it sent a letter to the government of Japan seeking approval for bilateral site surveys for locations that could support contingency operations. While a good firststep, this letter did not specifically focus on other alternatives in Okinawa—only 1 of the 12 options was located in Okinawa, and some suggested alternatives were located over 1,500 miles away. Moreover, not all of the site surveys have been completed, and Marine Corps and U.S. Forces–Japan officials we spoke with stated that the need remained for alternate runways to be identified.

As indicated by Unified Facilities Criteria 2-100-01, DOD has identified limitations and conditions that affect Camp Schwab's installation's ability to execute mission support with respect to the runway. Although Marine Corps and Pacific Command officials said the government of Japan is ultimately responsible for replacing the lost requirements by providing a longer runway elsewhere, DOD could be identifying other runways in Okinawa that would support mission requirements, which it could present to the government of Japan to help resolve this issue. By planning to construct a runway at Camp Schwab that does not have the needed capabilities, and until the site surveys are completed and an alternate runway is selected to replace those needed capabilities, DOD risks not supporting needed mission requirements and the issue remains unresolved.
