12/04/2013: According to a Japan Update story published on 12/4/13:
Two of the Navy’s new P-8A Poseidon reconnaissance aircraft have arrived at Kadena Air Base.
The P-8’s long-planned arrival in the western Pacific comes about a week after China unilaterally declared a broad swath of the East China Sea’s air space as its national air defense identification zone, and demanded that military and other aircraft identify themselves and file flight plans with the Chinese government.
Navy officials say the two patrol aircraft left Naval Air Station Jacksonville, Fla., on Nov. 29th, and later landed at Naval Air Facility Atsugi for refueling before touching down in Okinawa.
