319th MS LCCs Loses Comm to LFs

Missile Unit Experienced Communications Disruption: The 319th Missile Squadron headquartered at FE Warren AFB, Wyo., overseer of 50 Minuteman III ICBMs, experienced "a disruption of communications" between its five launch control centers and the missiles this past Saturday, Lt. Col. John Thomas, Air Force Global Strike Command spokesman, told the Daily Report Wednesday. He said the evidence so far points to a mechanical part failure associated with the missile complex's primary communications system. Somehow the electronic queries that the LCCs send out to each missile to verify its health and status got out of sync and created a transmissions logjam, kind of like 50 people trying to speak simultaneously on the same walkie-talkie frequency. Thomas said it took the missileers about 45 minutes to diagnose and isolate the issue. They switched control of all 50 missiles to one of the LCCs. (Normally each LCC controls 10 missiles.) In short order, all but one of the LCCs were back in the network. However, one of the squadron's LCCs remains offline for additional study of the anomaly, he said. Thomas said there's no evidence of tampering or malicious conduct. USAF technical experts think the issue is similar to ones that occurred in the late 1990s at Malmstrom AFB, Mont., and Minot AFB, N.D., he said. The missile crews at FE Warren had multiple safety, security, and command and control systems that were available throughout this event. Thomas said there was never any danger of unauthorized missile launch and the missiles' wartime capability "was never affected." And there was no outright outage of communications or power as some press reports have indicated. (See also Associated Press report and AFPS report by Terri Moon Cronk.)


As the article said the has happened at all three Minuteman Wings what is the possibility of a single bad control panel in the supply system that never get fixed as the problem can't be duplicated in a maintenance shop causing the problem at all the wings.

I remember a MMM Launch Verification Panel that if entered a specific Flight, LF and timing combination would turn a PLCB into a PLCA and retarget the entire squadron. The panel moved from squadron to squadron always causing the same problem that could never be duplicated in a maintenance shop. The panel was eventually euthanized with a hammer to get it out of the supply system.

Out of all the news articles I've read, this is probably the one that gives the most accurate picture of what happened. It's probably because they talked to someone that actually understands the system. All the other news organizations used either military officials who had no idea how the Minuteman system worked, or retired military advisors who had no clue either, as their sources. They all fail to mention that the missiles were still launch capable and able to be launched by ABNCPs, and the RVA security camera system was not affected by this since it uses a totally seperate system to beam back its video to the MAFs.
