A submarine's weakness: its software?
> the navigational software on the $3B warship is far less capable any maps app on your phone. The software, called "Voyage Management System" (VMS), is the hub of all the ship's planning. But it can't even do basic safety-of-ship alerting.<p>My phone can do "safety-of-ship" alerting? I'm the first to shit on defense software, it's my background, but map software for a submarine is safety-critical. While submerged it's basically their eyes. It has to be more reliable and trustworthy than possibly any other map software. Not only this but navigation information would have to be fused together from GPS as well as INS (inertial nav).<p>My 2 cents. Background in defense but not submarines.
