Well, if you had been on a the commisioning crew of a FLT-IIA ship (DDG 79 and later, I believe), you would have been confronted with an engine controller using Unix (HP/UX to be exact). There was also a redundant engine monitor/controller running on NT 3.51 as an experiment, but as I said, it could crash totally and not affect anything. I believe the Navy just wanted to try it out shipboard to see how NT handled things. Both of these systems were of course coded in Ada for extra reliability. To give everyone else an idea of the lead times we are talking about here, I think I finished up development on that system in '96, and the first ships with them were commissoned last year. The sixth one won't be commissioned until 2003, and there are currently plans for up to six more after that one. Who knows how long they will be sailing after that. But during this whole time the Navy is going to need copies of the OS and the ability to purchase spare motherboards, etc. of 1995 vintage. Not many vendors keep the capability of making "obsolete" parts for more that a couple of years. This is why many are a bit skeptical about using commercial technology. >We also we experimenting with the "Smart Ship" initiative, but no >existing ship's systems were ever going to be interfacing with the LAN >or any general-purpose OS.
