Secret List of U.S. Military Bases to Replace Gitmo

The U.S. military has prepared a list of U.S. military bases that could be used to house as many as 250 detainees currently being held at the U.S. Naval base in Guantanamo Bay, military officials tell ABCNews.com.

The list — which includes Camp Pendleton in California, Fort Leavenworth in Kansas; the Marine Air Station in Miramar, California; and the U.S. Naval Consolidated Brig in South Carolina — has been circulated in a classified brief to members of Congress and was prepared by the Pentagon’s Joint Staff.

President-elect Barack Obama is expected to order that the Guantanamo Bay detainee facility be closed on his first day in office, officials say. Officials say it would take at least a year to prepare a new prison and transfer the detainees.

The preliminary list was based on cost, logistic, and security concerns, but the Department of Defense is expected to present a more comprehensive recommendation based on a variety of factors, according a military official.

Camp Pendleton was determined to be the least expensive option and officials say its vast 125,000 acre size would allow for a new prison to be built in an isolated and secure area.
