It’s been a sweet busy week and I nearly didn’t make a posting. That is until I spotted an ancient piece in this area garage doors and the Navy. The headline reads “” Telephone system signal from U.S. Navy submarine base blamed for mystery of garage doors in Connecticut opening and closing at random” (see: http://www.dailymail.co.uk/news/article-2178027/Telephone system-signal-U-S-Navy-submarine-base-blamed-mystery-garage-doors-Connecticut-opening-closing-random.html; which is also the photo source). The essence of the report is that telephone system signals from the Naval Submarine Base New London (which is gives its street address as Groton, CT) were the probable cause of the bewitched garage doors. The sub base noted that the signals were part of the Enterprise Land Mobile Telephone system (ELMR) System. A quick Google search came up with RadioReference.com which claims that “This system is deprecated, and may no longer be in use or is superseded by another system. (see: http://www.radioreference.com/apps/db/?sid=6804)Having started my career in the EW/SIGINT world I know that there are excellent things and terrible things associated with jamming. For those of you who are not EW aficionados, jamming means overpower a friendly signal so that its intended receiver cannot receive it.The excellent news is that you can deny the enemy the effective use of his transmitters be they radios, television broadcasting or mobile phones. The terrible news is that it’s not stealthy. Targets generally know when they have been jammed. Another element is that jamming is generally a broad based weapon importance all electronics are effective; although there are some ways to jam only selected frequencies.The use of EW can also have a psychological effect. For example if an enemy force feels that they are not only surrounded physically, but they are cutoff electronically, this may induce them to give up.While TTP should dictate that EW should easily be brought into play, this is not necessarily the case. The tactical fighter typically does not have EW resources on hand. Furthermore, a sophisticated analysis needs to be performed of the impact zone of the proposed jamming to determine the nature of guarantee impact. What does this all mean?It means that the MISO CDR needs to be thoroughly familiar with and connected to their counterparts in other disciplines. Today’s posting scratches the surface in this area EW. The posting urges MISO CDR not to overlook adapting tools of combat that have not typically been included in PSYOP or MISO.Reader comments invited as always.I’m presenting at the RSA Talks in San Francisco next week – shoot me a comment if you want to connect.
