A generic Corvette-sized Ocean Patrol Vessel
According to the data there is an organization named Oceans Guardians, they offer private maritime security to protect vessels from piracy and defend against terrorists. It appears they have acquired three vessels which are described as "Ocean Guard Vessels, corvette sized ocean patrol vessels with fast response capability". Named OGV Defender, OGV Protector, OGV Preserver they are available by charter agreement for unit or fleet protection. While the data was rather vague we did manage to get an answer on whether the vessels are armed. NAUTICAL LOG was informed that suitable modules could quickly be loaded aboard in preassigned positions similar to the procedure used for the armed merchant vessels and famous Q-ships of World Wars 1 & 2.
So something is available to the Institute for Cetacean Research (ICR) that operates the Japanese Whaling Fleet (JWF). The problem that the ICR has is Japan's Constitution does not allow its Armed Forces to engage other than in defensive mode. This is why the Japan Armed Forces are always described as 'Self-Defence Force'. How this applies to the Japan Coastguard is a little vague under both Japan National and International Law. The last two seasons one of the JWF vessels was operated by the civilian whaling crew but had a Japan Coastguard armed team on board. There was considerable discomfort in many circles in Japan about this being done. Now it appears a possible solution has emerged by the hiring of non-Japanese private maritime security and the chartering of their OGV's.
So silly season - maybe not.
