i actually build destroyers (think weld on new destroyers). i was told they are designed for future “alternative weapon” additions… there is a lot of confidential and top secrete $#!7, so im usually the last person in the world to hear anything new on these ships…
Pulsar, you working on the DDX? I hear the Navy’s gonna outfit it with railguns. That is if they ever finalize the design. It seems like prototypes keep nailing velocity milestones, but then the Navy wants the thing to shoot even faster so they push back the timeline. It doesn’t matter how fast the thing can shoot if you don’t have any on your ships…
Right now I think we have two ddg 1000s and two ddg 51s going, might be wrong though. I can’t say for sure what weapons they plan on equipping them with though. Above my pay grade lol… I actually went inside the verticle launch system yesterday on a ddg 100p, it was kind of amazing.
Last summer I got to sit in the captains chair of a 51 too shortly before it went out for sea trials. What other job do you get to sit on the captains char of a destroyer eating a soft srve cone? Yeah, they have soft serve icecream machines on board 
Mmmm. Ice cream :-)
