There no longer are Soviet submarines on the Pacific Coast, and consequently no US aircraft from Moffet air station flying over the coast and the peninsula to monitor them. It's been almost 20 years.
I noticed the last few days that the dish antennas are being dismantled at that site, and my understanding is that the Blue Cube will be demolished as part of the process.
I am no national security expert, or what the Blue Cube "campus" played in the times of the Cold War. I do know that I had seen the Moffett planes and that "campus" numerous times, and really did not think much about just what it was all about. I am glad that such operatons are no longer considered an important part of our national security, and can be dis-mantled.
The nature of threats, here in the States and elsewhere, is different and perhaps more pernicious. But I think a Blue Cube operation will not address them, and it is good to see it get retired.
I would love to see some community gymnasiums replace the dish antennas and the Blue Cube, but I don't think that is likely
