U.S. Admiral Samuel Locklear (C), Commander of the U.S. Pacific Command, is flanked by Shigeru Iwasaki, Chief of Japan's Self-Defence Forces Joint Staff, during an inspection of the Patriot Advanced Capability-3 (PAC-3) land-to-air missile deployed at the Defence Ministry in Tokyo April 11, 2012. Isolated North Korea said on Wednesday it was injecting fuel into a long-range rocket ahead of a launch condemned by its neighbours and the West as a disguised long-range ballistic missile test. The launch, set to take place between Thursday and next Monday, has prompted neighbours such as the Philippines to re-route their air traffic. Japan said it would shoot down the rocket if it crossed its airspace. REUTERS/Yuriko Nakao (JAPAN - Tags: MILITARY POLITICS)
