How exactly does the U.S. Corsair Unmanned Surface Vessel work?
On the outside, it might look simple.
But inside, it packs a massive 1,000-pound warhead within a highly modular payload bay.
Powered by a hybrid generator and a completely silent electric motor, it easily pushes past 35 knots.
For the first time in an active war zone, on July 12th, 2026, the U.S. Navy deployed this platform to execute an unprecedented strategy: ramming the drones directly into an Iranian dry dock.
So, what happens at the exact moment of impact?
If configured with a G B U-31, the sequence is deadly.
Up front is the fuze, sitting right ahead of the 1,000 pound warhead. The second it hits the target, the fuze triggers the conduit rod, instantly detonating the payload.
In this unclassified Centcom footage, you can clearly track two of these sea drones one flanking from the right, and the other rushing up the center.
But what exactly are they targeting Sitting elevated in the dry dock is an Iranian submarine.
You might be asking,
‘Why not just send a stealth fighter jet?’
It comes down to the physics of a waterline strike.
The military needed a devastating surface-level impact.
Compared to a top-down aerial bombardment, this blast surges inward and upward, completely shredding the submarine and the dock’s structural supports from every direction.”
