Japan has launched their newest radar spy satellite, the Information Gathering Satellite (IGS) Radar 5, aboard the H-2A rocket from Tanegashima Space Center. It joins an existing constellation of spy satellites which Japan began assembling in 1998 following a North Korean missile launch that flew over Japanese territory. Officially, the IGS program supports civilian needs, such as disaster awareness, but the unspoken main goal is to keep tabs on Japan’s enemies. This launch of course was not in response to last week’s North Korean missile tests; satellites and launch vehicles take years to plan and procure. But I am sure Japan hopes for it to send a message all the same: we are watching.
