These are America's most intense electronic weapons

The Phasr was introduced in 2005 by the Air Force.

As another directed-energy weapon, the Phasr employs a two-wavelength laser system that temporarily blocks an aggressor's ability to see.

It's like opening your eyes in the middle of the night to someone shoving a blinding flashlight in your face. The Air Force casually calls this effect "dazzling" or "illuminating." Whatever you call it, this hand-held device effectively impairs anyone targeted.

The US has run several test flight experiments on the Airborne Laser Test Bed (ALTB). So far, they've worked out this killer firing sequence:

1. The ALTB uses one of its six infrared sensors to detect the exhaust plume of a boosting missile.
2. A kilowatt-class solid state laser, the Track Illuminator, tracks the missile and determines a precise aim point.
3. The Beacon Illuminator, a second laser, then measures disturbances in the atmosphere, which are corrected by the adaptive optics system to accurately point and focus the High Energy Laser (HEL) at its target.
4. Using a large telescope located in the nose turret, the beam control/fire control system focuses the HEL beam onto a pressurized area of the missile, holding it there until laser energy compromises the missile’s structural integrity causing it to fail.

You may have heard of the Navy's Next Generation Jammer program (NGJ).

Radar jamming can disable the enemy's command and control system ahead of an offensive attack. NGJ will be used on the Boeing EA-18G, the aircraft for airborne electronic attack operations.

Another example of electromagnetic jamming is Counter-RCIEDs (Radio Controlled Improvised Explosive Device). You can see the Marine Corps' Chameleon system here.

Troops can mislead enemy decision-makers about their intentions, prompting the enemy to take specific actions or inactions and making it difficult for the enemy to establish an accurate perception of reality.

Using the EM spectrum, they can disrupt communication and intelligence systems to insert deceptive information.

Military Deception (MILDEC) operations apply four basic deception techniques: feints, demonstrations, ruses, and display.

The AGM-88 HARM (High-speed anti-radiation missile) is used throughout the Air Force for suppressing surface-to-air radar warning systems.

Anti-radiation missiles help neutralize hostile airspace and take out the enemy's ability to defend itself.

As Air Force officials have noted, "Coalition forces in Operation Desert Storm operated 'at will' over Iraq and Kuwait after gaining control of the EM spectrum early in the war."

Boeing has test-flown a nonlethal missile that fries electronics while minimizing collateral damage (like civilian deaths). You can read about CHAMP here.

The AN/ALE-55 fibre-optic decoy is towed behind to protect fighters, bombers, and transport aircraft from radio frequency-related threats, such as an incoming missile's tracking on the aircraft.

There are three layers of protection though, so the idea is that a target track is eliminated from the start.

If all else fails, the intelligent decoy will lure the missile away to become the target and deny the enemy a hit.
