It looks like a target to me.
A single B-1B pass at 700ft and Mach 1.2.
Hell, the B-1 might even get there before anyone there knows to get the birds aloft:)
I wonder how much China spent on their stationary aircraft carrier built on coral?
I've been promoting for years mysterious explosions turning the ruined atolls into so much rubble.
These Chinese atolls make me think of France’s Maginot Line.
Of course the comparison is not exact.
