Japan has had an epiphany. And they have added again to the cost of running nuclear plants. Even mothballed nuclear plants are targets.
So they dedicated 2 large ships with helo pads, to be parked off some nuclear plants.
Scenario — Cruise missiles are around $1M each. Take 3, please, and launch at the nuke plant primary substation (electrical center), one at the DG backup generators, and one at the main fuel storage. = Station Blackout and within hours, meltdown.
Two new 1,500-ton vessels with helipads will be deployed between fiscal 2019 and 2020 to the coast guard’s Tsuruga office in Fukui Prefecture where several nuclear plants are located, according to the sources.
