– Maritime Executive – An armada of carriers, cruiser, destroyers and submarines gathered off Japan’s coast on Sunday in a display of naval power that showcased Tokyo’s latest warships and signalled wider engagement by the U.S. Navy in the western Pacific.

NAPSNet – This is a study of Japan’s ground-based signals intelligence (SIGINT) stations, the 17 (soon to be 19) major facilities that intercept, monitor, collect, process and analyse foreign electronic signals. Official statements convey nothing of the scale or detail of the Japanese SIGINT effort, which is probably the third or fourth largest SIGINT establishment in the world. These Japanese ground signals interception and location facilities are integrated with its air and missile defence radar facilities. Together with Japan’s own long-range underwater surveillance systems, and combined with the Japan-based US parallel air, ground and underwater surveillance systems, they take Japan a very long way towards its stated aim to ensure information supremacy in the region. As potentially lucrative targets in the event of war, destruction of these important but vulnerable facilities could alter escalation dynamics in such a way that the widespread assumption that a Japan-China armed conflict could be controlled before substantial escalation may not hold true.

– USNI News – The government of Prime Minister Shinzo Abe has proposed major changes in Japan’s defense policy, with strong implications for the United States and U.S. armed forces in the Pacific.

The new view from Tokyo takes in the Indian Ocean and, especially, the disputed South China Sea. Driving this change, of course, is an alarmingly assertive China.

– Australian National University Press – A must read new book by Professor Desmond Ball which is freely available.

He writes that Japan is quintessentially by geography a maritime country. Maritime surveillance capabilities – underwater, shore-based and airborne – are critical to its national defence posture. This book describes and assesses these capabilities, with particular respect to the underwater segment, about which there is little strategic analysis in publicly available literature.
