The Air Force Should Assure Defenses Against Nuclear EMP Threats As It Seeks Electromagnetic Spectrum Superiority

How does Wi-Fi work? An electrical engineer explains

Though you can’t see them, radio waves are all around you all the time, carrying information. For most people, some of those radio waves are Wi-Fi signals. Wi-Fi is the catchy name an industry alliance came up with to market devices that transmit large amounts of data over short distances using radio waves. The letters don’t stand for anything. Wi-Fi, like broadcast radio and cellular telephone signals, is based on scientific discoveries dating back to the late 19th century. When electrons moving through a wire are made to alternate directions periodically, something magical happens. Electrons in another wire, located at a distance, start to move up and down in sync, as though they were telepathically connected.

Spectrum Superiority Key To All Domain Operations: Gen Hyten « Breaking Defense - Defense industry news, analysis and commentary

By   Theresa Hitchens on January 07, 2021 at 6:03 PM Gen. John Hyten WASHINGTON: As the Joint Staff develops a Joint Warfighting Concept to guide America’s new way of war, All Domain Operations, it’s becoming increasingly clear that control of the electromagnetic spectrum is key to its success, says Vice Chairman of the Joint Chiefs of Staff Gen. John Hyten. And that means setting spectrum requirements will be key to ADO. “We have to be able to effectively fight and win the electromagnetic spectrum fight right from the beginning that is, electronic warfare in every domain,” Hyten told the Association of Old Crows (AOC). Hyten chairs the Joint Staff’s Electromagnetic Spectrum Operations Cross Functional Team, and, in addition, is the “senior designated official for EMSO, electromagnetic spectrum operations, in the Department of Defense.”

Adios, 2020! Here are people, programs, and budgets to watch for in 2021

Biden’s Budget  In the absence of news, we’re sticking by our way-too-early predictions of flat defense spending, at best especially with Congress on the verge of passing another coronavirus stimulus package, this one totalling nearly $1 trillion. If Republicans retain control of the Senate, expect lesser cuts. If Democrats take control after two early-January Georgia runoffs, expect deeper cuts as they focus on priorities other than defense.  In the meantime, the Trump administration last week released what it calls the “FY 2022 Fiscal Planning Framework,” a blueprint for what it calls the Pentagon’s top spending priorities. It’s an unusual attempt by a lame-duck administration to shape the next budget, and may become an important reference for congressional Republicans when they review Biden’s fiscal 2022 budget proposal. Typically, an incoming administration sends its first budget plan to lawmakers a few months later than the more typical February delivery. Tha

Today s D Brief: Feds scramble amid biggest hack in years; COVID vaccine arrives; NDAA passes over veto threat; Electors vote today; And a bit more

The U.S. government was hit with a seemingly new kind of cyber attack (or intrusion ) that gave hackers access to sensitive email systems possibly as early as March. The attack was only discovered this weekend, according to Reuters, whose cybersecurity reporter Chris Bing broke the story Sunday afternoon. And its discovery was “so serious it led to a National Security Council meeting at the White House on Saturday,” Bing reports.  Rewind: You may remember last week the cybersecurity firm FireEye announced that it had been hacked by an unknown “nation-state.” The new discovery of these federal-level breaches is the result of FireEye’s post-attack forensics, which you can read in full, here.
