Those ‘Doomsday Planes’ Have Nothing to Do With Trump’s Covid-19 Test

Okay, so it is interesting to discuss whether plane spotters’ observation of two E-6B takeoffs and trump’s tweet about his CoViD positivity minutes later were related (probably not, it appears). But the backstory about these aircraft is more fascinating:

 

‘…E-6Bs, which are based on Boeing 707s, are essentially communication relay stations built to receive military orders from the president of the US and the secretary of defense, and then convey those commands to US ballistic missile submarines. They’re also equipped to remotely control Minuteman intercontinental ballistic missiles through a platform called the Airborne Launch Control System. The idea is for E-6Bs to serve as a redundancy in case ground-based communication systems are disrupted. And they’re also crucial for establishing line-of-sight communication connections that require proximity. The E-6B mission overall is known as TACAMO, or Take Charge And Move Out…

The planes have some dramatic capabilities. One of the most significant is their Very Low Frequency communication platform, which is used to reach nuclear ballistic missile submarines down to 60 feet below the ocean’s surface. These stealth submarines must conceal their positions and often can’t rise to shallower depths or send up buoys to aid communication. Instead, both communication relay planes and the submarines themselves must be equipped with massive antennas, and even then VLF systems are still extremely low-latency, low-bandwidth, and low-throughput, meaning it takes a long time to send very small amounts of data. To transmit even the shortest messages to deep-sea submarines, E-6Bs perform special airborne maneuvers. These are essentially steep, tight turns that go on for long periods of time, looping the plane around and around to get the antennas in a vertical position transmitting straight down into the water. Other military planes are also equipped for VLF communication, but it is especially core to the mission of E-6Bs…’
