Where would the repairs to the ASDS happen? Can they fix it where it berths, or does it go to another port with the proper equipment and materials? I lived in Kansas for a long time, so I know nothing about the sea/am the ultimate landlubber.Thanks!
And JRtI had its wings installed in port, not at the Louisiana shipbuilder.
I was the one that speculated that there may have been a hit dead center. Shadows from scrap that was nearby was the other possibility. This and other pictures prove that there never wasn't a hard hit there.
Anyone know enough about metallurgy to estimate the minimum force required to puncture the steel plating?That and dry mass would give a lower bound on the velocity at contact.
Here are some more photos of the ASDS I took today. Drone, Panorama, and some shots from the Exploration Tower. Full Album:(Also caught a delta stage rolling up to the base)http://imgur.com/a/SHt5g

By the look of that tear and the possibly wood structure below, I'm wondering if the deck is some type of composite. One inch steel would have peeled back, not torn; maybe quarter inch plate could tear... And why would you install timbers below decks?

(USS Cole comes to mind but probably much thicker steel plate)
The blast ripped a 40-by-20 foot hole in the Cole's half-inch-thick hull plates below the forward smokestack,

It looks from that photo like a big petal of the "peeled down" steel has been cut away. Timbers may have been to support the bent "petal" from below while it was being cut out.
