STAY AHEAD OF WHAT’S COMING

If this matters to you, you should be seeing it in real time - not after it’s already happened.

BLUF

One detonation. One pulse. One nation gutted from the inside without a single building falling. Tonight on America Under Siege we walk through what happens when a nuclear warhead goes off two hundred miles above the heartland and the entire continental grid drops in seconds. This is the first-strike weapon our adversaries have studied for decades, the asymmetric play that lets a smaller nuclear power level the field against America without ever putting a soldier in the fight. Vehicles stall mid-lane, aircraft lose flight controls, every cell tower goes silent, and the lights never come back on the way they did before. Within hours the public stops calling it an outage. The Smith family figures it out fast, and so will you. This is not theory. The threat is real, the vulnerability is mapped, and the silence is closer than most Americans want to believe.

WHAT YOU NEED TO UNDERSTAND

A high-altitude electromagnetic pulse, or HEMP, is created when a nuclear device is detonated roughly thirty kilometers or more above the Earth’s surface. The detonation releases gamma radiation that interacts with the upper atmosphere and produces three distinct waveforms in sequence, each one designed to break a different layer of our infrastructure. The E1 pulse hits in nanoseconds, frying solid-state electronics, protective relays, SCADA controls, vehicle computers, and the digital nervous system that runs every modern grid operation. The E2 pulse follows almost immediately, behaving like a continental-scale lightning strike that overwhelms the surge protection that did survive the first wave. The E3 pulse is the slow killer. It induces enormous quasi-direct currents that flow through long transmission lines and saturate the cores of large power transformers, the same way a severe geomagnetic storm would, which causes hot-spot heating, insulation breakdown, and physical destruction of equipment that takes twelve to twenty-four months to manufacture. America runs on roughly two thousand of these large high-voltage transformers and most of them are built overseas. Once they go, the grid does not come back on a timeline that civilization can survive. The 2017 EMP Commission, the 2018 Department of Homeland Security catastrophic power outage study, and decades of testing at Oak Ridge National Laboratory all point to the same conclusion. We are wide open, and our enemies know it.

THE EMP TEST THAT ALMOST KILLED A MAN

Most preppers talk about EMPs. We strapped one down and hit it with 400,000 volts of static discharge - over 100 times - to find out if the gear you’re betting your family’s survival on actually works.

To our knowledge, no one else has put EMP Shield through this kind of punishment and published the results.

Then it got worse. After we wrapped this test, an 800,000-volt Marx generator tried to ground through Steve, standing 25 feet away on a tractor tire. He’s lucky to be alive. We caught it on camera.

▶️ Hit play. Then keep reading - what comes next is why Guardians get the full brief.

STAND WITH THE MISSION ...

If you rely on our SITREPs and ThreatWire briefings to stay ahead of what’s coming, upgrade to Guardian today. Your support keeps SDN independent and our intelligence flowing, no filters, no sponsors, no censorship.
