Here's the kicker-- when I read the headline (having been an ICBM crew member 1983-88...and back in a senior leader capacity in that community in the late 2000s), I was fairly certain that I knew what system they were talking about. When I opened the story, it turned out I was right!
Here are some things that the story didn't say, however:
While the system did originate in the 1960's as "465L SACCS" (https://en.wikipedia.org/wiki/Strategic_Automated_Command_and_Control_System), it was upgraded in 1986-87 time frame to something called "SACDIN" by Lockheed Martin. So it's not a "1960s system", it's a "1980s system"!
The system is too old, I agree...but not due to military or government stupidity or lack of foresight (as the article seems to imply), but rather the fact...
