HSV-2 is doing good work in Katrina relief.
Look at
www.jerrypournelle.com , specifically his "Current Mail" for the last week. It seems that Dr. Jerry's son, Lt.Commander Phillip Pournelle USN, is the exec of said vessel, and has been sending his Dad emails, with pics, of what they've been up to.
Which is basically resupplying everybody with critical stuff, at high speed. I think he wrote that because they draw only 12 feet, they are the only halfway-sizable vessel able to get in and out of Pensacola, what with the obstructions and demolished nav-aids from the *previous* hurricanes.
Pournelle, Jr., writes of the tremendous damage to infrastructure- huge barges high and dry, yards inland from unbroken trees, and has some good quotes from Miss. River Pilots, too.
As some have written above, these new ships don't have very many in their complements, and Mr. Pournelle was concerned about the 40-odd folks they have just wearing themselves out with all of the physical labor.
