Because of sequestration budget cuts, the CHAMP missiles did not become operational under the Obama administration. But after I emailed then Trump National Security Adviser H. R. McMaster in August 2017 information about CHAMP that I was about to include in my book, The Trump White House, he thanked me for letting him know about the capability, agreed to an interview, and ordered a briefing from the Pentagon." The missile, which reportedly has a range of 700 miles, is delivered from bombers and flies at a low altitude and delivers “sharp pulses of high power microwave (HPM) energy.”
"The pulses delivered by the weapon system can reportedly destroy electronic systems that are buried deep inside mountain bunkers and underground military facilities.
"Kessler reports that U.S. officials believe that even if North Korea and Iran tried to shield their military equipment that their efforts would not be sufficient. Kessler adds:
Most amazing of all, the missile renders inoperable any radar that might detect it as it flies to and from a target. Thus, a country cannot take out CHAMP before it strikes and has no way of knowing why its facilities have suddenly gone dead.
CHAMP missiles emitting HPM also differ from an electromagnetic pulse (EMP) attack that is created by detonating a nuclear weapon in the atmosphere. Because it is targeted, HPM leaves intact civilian facilities needed to sustain life. . . .
