It took me a minute to figure out what was what in that unusual photo. Strange that an inanimate object, and one intended to destroy, would be blessed.
I wonder if this one has a modified design to carry six missiles instead of four? I know Japan was working on its own variant since China’s stealth fighter’s internal bays can hold six missiles.
I’m afraid blessing of weapons is a practice as old as warfare itself … and hardly limited to Shintoism. Think of how we still christen warships. We may think of it differently, but is essence it’s the same thing.
