Era il 1979 quando l’autore pubblicò un lavoro pionieristico sull’argomento sulle IEEE Transactions:

Measurements of Complex Dielectric Constant of Human Sera and Erythrocytes.

Non ci voleva molta fantasia per comprendere come il campo fosse di consistente interesse militare.

In questi quaranta anni sono stati compiuti consistenti progressi, che hanno generato, inter alias, il Champ.

«The Counter-electronics High Power Microwave Advanced Missile Project (CHAMP) is a joint concept technology demonstration led by the Air Force Research Laboratory, Directed Energy Directorate at Kirtland Air Force Base to develop an air-launched directed-energy weapon capable of incapacitating or damaging electronic systems.

On October 22, 2012, Boeing announced a successful test of the missile. CHAMP took out seven different targets before self-destructing over empty desert.

The U.S. Air Force expects to have technology for a steerable counter-electronics weapon “available” in 2016, when a multi-shot, multi-target, high-power microwave (HPM) package will be tested aboard an AGM-86 ALCM. By the mid-2020s, HPM weapons are expected to be integrated onto a “JASSM-ER-type weapon,” and on small reusable platforms like the F-35 Lightning II and unmanned aerial vehicles. HPM weapons are not yet a program of record, but they are desired in situations where one target building needs to be engaged and shut down, while not affecting the buildings around it. Other potential improvements could include increasing autonomy and putting it on hypersonic missiles.

The CHAMP is superior to other electronic warfare weapons because it destroys electronics, rather than jamming which temporarily affects systems that come back online when it stops being applied. The Air Force has two separate “capability portfolios” for weapons and electronic warfare equipment which have been having trouble joining to produce an operational CHAMP system, so a cross-functional study is to be delivered in summer 2015. Congress has suggested repurposing excess cruise missiles demilitarized under the Intermediate-Range Nuclear Forces Treaty to turn them into CHAMP weapons without violating it. On 14 May 2015, the Air Force nominated the Lockheed Martin JASSM-ER as the optimal air vehicle to carry the CHAMP payload. CHAMP is capable of up to 100 shots per sortie.» [Fonte]

Ricapitoliamo.

Gli Stati Uniti, e con loro le altre due superpotenze, hanno in arsenale tutta una congerie di armamenti altamente sofisticati, sia di attacco sia di difesa.

Sarebbe davvero ingenuo pensare che gli stati maggiori pubblicizzassero tutti i marchingegni disponibili, ma qualche notizia filtra pur sempre dalle strette maglie del riserbo. Spesso informazioni frammentarie ma chiaramente intendibili da quanti ne abbiano pratica.

La Korea del Nord riesce al momento a costruire missili balistici, ma è priva di tutto quel contesto di armamenti al contorno che li rendono effettivamente operativi. Non si vuol dire che siano fuochi di artificio, ma non poi che siano poi molto di più.


Nbc News. 2017-12-05. Microwave weapon could fry North Korean missile controls, say experts

The U.S. has microwave weapons that proponents believe could stop North Korea from launching missiles by frying their electronics.

The weapons were discussed at an August White House meeting related to North Korea, according to The microwave weapons, known as CHAMPs, are fitted into an air-launched cruise missile and delivered from B-52 bombers. With a range of 700 miles, they can fly into enemy airspace at low altitude and emit sharp pulses of microwave energy to disable electronic systems.

“These high-powered microwave signals are very effective at disrupting and possibly disabling electronic circuits,” said Mary Lou Robinson, who heads development of the weapons at the Air Force Research Laboratory in Albuquerque, in an exclusive interview with NBC News.

U.S. officials with direct knowledge.

Advocates say they could be used to stop North Korea from launching missiles by targeting the ground controls and the circuitry in the missiles themselves. The weapons are not currently operational.

How does a high-power microwave (HPM) weapon work?

“Think about when you put something in your microwave that has metal on it,” said Sen. Martin Heinrich, D-N.M. “You know how badly that goes? Imagine directing those microwaves at someone’s electronics.”

Sen. Heinrich, a member of the Armed Services Committee, began his career as an engineer at the Air Force Research Laboratory in Albuquerque.

“Command and control centers are filled with electronic infrastructure which is highly vulnerable to high powered microwaves,” said ret. Lt. Gen. David Deptula, who ran the air wars in Afghanistan and Iraq and retired as the head of Air Force intelligence.

The Air Force and other government agencies have been working on the weaponization of microwaves for over two decades. Various emitters have been employed on the ground — in Afghanistan and Iraq, they have been used to disable improvised explosive devices (IEDs) and small drones.

But turning a high-power microwave into a strategic weapon was slowed by the need to reduce the size and weight of the emitter and then match it with an onboard power source sufficient to drive the microwave pulses.

The Air Force Research Laboratory began work on CHAMP, which stands for Counter-electronics High Power Microwave Advanced Missile Project, in April 2009. The lab fitted the HPM emitter into a non-nuclear version of a Boeing-built air-launched cruise missile.

By October 2012, according to Air Force documents, CHAMP was ready for an operational test. A B-52 bomber launched the missile over the Utah Test and Training Range, a 2,500-square-mile testing area larger than Delaware. Mocked-up buildings were rigged with communications and computer systems that simulated possible enemy capabilities.

Many of the targets, according to internal CHAMP budget documents obtained by NBC News, involved “representative WMD production equipment” found in Iran and North Korea.

“It was as close to the real thing as we could get,” Keith Coleman, CHAMP program manager for Boeing, said after the test.

“It absolutely did exactly what we thought it was going to do,” said Robinson. “We had several different target classes in those facilities, and we predicted with almost 100 percent accuracy … which systems were going to be affected, which systems failed, and how.”

The 2012 test, the only one so far declassified by the Pentagon, has been followed by additional tests and various experiments to advance the microwave technology. A new power source was incorporated, turning the microwave weapon into what the Air Force calls “Super CHAMP.”

According to a December 2016 Air Force Research Laboratory document, the low-flying missile is now “capable of flying into a contested area and disabling an adversary’s electronic systems.”

Robinson said “there is no doubt” in her mind that HPM weapons work.

Could a high-power microwave weapon actually be used against North Korea?

Deptula said he believed the U.S. could use an HPM to disable a ballistic missile on a North Korean launch pad, and that there are many advantages to using microwave weapons in a North Korean scenario.

They work in all weather, said Deptula, which helps in the Korean climate, and “they’re employed at the speed of light. You can’t get much faster than that in terms of achieving desired effects.”

The main operational constraint, Robinson said, is that the microwaves from the CHAMP emitter “aren’t very far-ranging.”

Robinson said that in order to disable a missile or launcher’s electronics, CHAMP would have to get “close” to the target. How close is classified, but “it’s not tens of feet,” said Robinson.

Sen. Heinrich said the challenges to using the weapon are “less technical and more mental. You spend years trying to perfect these things, and the tendency in the Pentagon is oftentimes to continue to try to perfect something. My tendency is to say, ‘Hey, we’ve got something that really works. Let’s take those things and put them into the hands of our men and women in uniform.'”

Deptula adds that one of the differences in using microwaves as opposed to explosives is assessing the effects — the destruction they wreak is not visible.

But Deptula said that “there are means to determine whether or not you’ve achieved your effects beyond the traditional battle damage assessment using photography.”

Speaking in February 2016, Air Combat Command chief Gen. Herbert “Hawk” Carlisle said that a number of high-power microwave units were being kept as “weapons to use in a contingency.”

Robinson said that “it would take a little bit of time” to make the missiles operational. Two Air Force officials with knowledge of the current plans and capabilities say that CHAMP could be ready for use quickly, possibly within days.

The White House declined to comment.


Axios. 2017-12-05. Microwave weapon could disable North Korean missiles, experts say

The U.S. has weapons that could dismantle North Korean missiles by firing microwave energy to interfere with ground controls and power circuits within the missiles themselves, NBC reports, citing sources with knowledge of a White House conversation related to the North Korean threat.

The details, per NBC: The microwave weapons can be fit onto air-launched cruise missiles and released from B-52 bombers. They can fly into enemy airspace at low altitudes to fire off microwaves. A word of caution: We have no real indication as yet that such a strategy would be attempted, or prove effective, if the situation should arise.
