Nope.

Whoops, sorry about that. Wrong link.

Pity...that would have been too perfect
You are correct, my mistake.
Wrong N.O. link and the ship is not amphibious - it is a transport for amphibious ships.
The New Orleans is an LPD, LAnding PLatform Dock. She is an amphibious assault ship, tonnage at about 25,000 tons. Fourth San Antonio Class LPD commissioned. She was commissioned in 2007.
She is designed for delivering MArines to shore either by LCAC (Air Cushioned Landing Craft), or by helicopter and is well armed for self defense.
