I would guess that the navy's computers can't run anything heavier than XP.

We had that problem at the IRS - and I suspect most other federal agencies.  The computers lacked the memory to be upgraded.

Wouldn't surprise me if a lot of the shipboard systems are still Intergraph hardware that tops out at 4 gigs. Another issue is it's probably a real PITA not to mention expensive to get new software certified for critical systems. It took NASA nearly 10 years to upgrade the shuttle to i386 processors. By the time they started flying with them the hardware was already several generations outdated.
