As the State Department flew its first group of evacuees out of Japan yesterday, the top U.S. military commander in the Pacific said the United States would be prepared to evacuate as many as 87,300 U.S. citizens.
Adm. Robert Willard, head of the Hawaii-based U.S. Pacific Command, said the U.S. is operating four commercial aircraft out of Narita Airport near Tokyo for citizens who want to leave the country.
The 87,300 people include U.S. military personnel and families in Japan, including the large naval base at Yokosuka, Willard said in a news teleconference from Camp H.M. Smith to the Pentagon.
From Navy Times:
Troops and families at several bases have received dire warnings to stay indoors if possible and to “secure eternal ventilation systems as much as practical.” That included Navy bases at Yokosuka and Atsugi, about 180 miles south of the damaged Fukushima Dai-ichi nuclear power plant.
Further U.S military involvement will hinge on the findings of a small assessment team sent to Japan Thursday from the U.S. Northern Command in Colorado.
