Secret New Submarine Equipment?
Found this picture of USS Jefferson City getting underway from San Diego on the official Navy website, and it looks like someone messed up. If you look at the hi-res shot, and then click on the icon on the lower right, then pan over towards the part of the deck between the aft escape trunk and the aft MBT vents, you'll see that the Jeff City apparently has the B1rD installation; it appears to be the CGU-11 mod. Don't tell anyone!
Update 0931: Here's the original image:
And here's a cropping that focuses on the new equipment!
Update 0946: I could only find one other site on the web that gives background information on the CGU-11.
