US: DoD awards nearly $250 million in contracts for pilot laser eye protection

The U.S. Department of Defense on September 28 2018 announced two contracts, each worth $98.3 million, for the development, manufacture and delivery of visors and other devices to protect pilots from blinding lasers.

The contracts went to Gentex and to Teledyne Scientific & Imaging, and will be completed by September 2024.

Earlier, on August 10 2018, DoD announced a $49 million contract for the Flash and Laser Airborne Protection System, which provides for research, development and manufacturing of photonic resistant material to protect air crews from flash blindness. Photonic shielding is used on high-value military aircraft such as Air Force One, but is not in widespread use.

The contract went to UES Inc. of Dayton Ohio, and will be completed by November 2024.

According to an October 1 UPI story, "the Pentagon started moving on improved eye protection for pilots after the Chinese military reportedly used lasers against pilots from a base in Djibouti, as well as in the South China Sea."

Israel: Laser-equipped drones to fight incendiary kites and balloons

The Israeli Defense Force has developed a laser-equipped drone to shoot down incendiary kites and balloons lofted by Palestinians to set fires in the Gaza Strip.

From late March to mid-June 2018, 450 fires caused by the aerial attacks burned about 7,500 acres of farmland and national parks, including 1,400 acres of wheat.

In response, the IDF has developed systems to locate the kites and balloons, either intercepting them or sending fire fighters to the landing locations. One interception technique uses a laser on a drone that in tests “has been successful in incinerating the incoming trajectory, neutralizing it and bringing it down.” It is expected to be deployed “soon” according to news stories in late June 2018.

UK: Average of 50 laser illuminations of military aircraft per year in UK

From 2013 through 2017, there were about 250 “laser-related” air safety occurrence incidents involving military aircraft (planes and helicopters) in UK. airspace.

It is not clear if these military incidents are included in the Civil Aviation Authority (CAA) statistics about laser illuminations of aircraft.

The Ministry of Defence figures, made public June 11 2018, were rounded to the nearest 10. The list below shows the reported military-related laser incidents in the UK, along with the CAA numbers for the UK and for overseas UK operators

2013 - 40 military, 1396 CAA UK home, 329 CAA UK overseas operators
2014 - 70 military, 1447 CAA UK home, 317 CAA UK overseas operators
2015 - 70 military, 1440 CAA UK home, 355 CAA UK overseas operators
2016 - 30 military, 1258 CAA UK home, 274 CAA UK overseas operators
2017 - 40 military, 989 CAA UK home, 243 CAA UK overseas operators

The information was released in response to a written parliamentary question submitted by former defence minister Kevan Jones, who said “New laws to deter those stupid enough to carry out these attacks might not be enough, and the Government should give police operating around air bases the resources needed to catch offenders.”

US: Marines to buy 1,653 eye-safe laser dazzlers

B.E. Meyers & Co. on May 29 2018 announced that the U.S. Marine Corps will be buying 1,653 “Glare Recoil” LA-22/U laser dazzlers. It contains a 250 mW 532nm green laser, with variable divergence from 4 to 70 milliradians. It uses three technologies to ensure the beam is eye-safe at any distance:

  • An infrared (1535nm) laser rangefinder determines the distance to a person or object. The closer the distance, the lower the laser power output.
  • Near-field detection shuts off laser emission if a person or object is too close to the laser output aperture.
  • A 3-axis gyroscope detects motion. If the Glare Recoil is suddenly moved, the laser shuts off until stability is resumed and an accurate determination of the distance to a person or object can be re-established: “This prevents hazardous irradiance in situations where Glare Recoil is moving faster than the laser rangefinder can detect objects and dose power output. This results in the prevention of eye hazard danger caused by rapid movement of the device (example: flagging) or improper situational awareness of the operator.”

With these technologies, the laser detects objects or people in the proximity of the beam and then self-adjusts the power output to maintain eye safety. The Nominal Ocular Hazard Distance is said to be 0 meters; the range is 10 feet to 10 miles.

Suggested uses include urban patrolling, cordon and search, crowd control, clearing facilities and security checkpoints.

The Glare Recoil is about the size of a Walkman tape player at 5.5” x 3” x 2”. It can mount on a rifle or be handheld.


Meyers also sells a Class 1M “Glare Helios” which has an FDA variance allowing sales to U.S. local, state and federal law enforcement, and U.S. flagged vessels.

US: Air Force wants 38,000 more laser eye protection glasses and visors

The U.S. Air Force on May 2 2018 issued a revised draft request for proposal (RFP), for 38,000 laser eye protection glasses and visors for aircrews.

While the original draft RFP was published for comments on March 27 2018, the revised request takes on additional urgency after the Pentagon on May 3 2018 accused China of aiming lasers at aircraft flying from a U.S. airbase in Djibouti. According to the Pentagon, two pilots had minor, short-term injuries as a result. The next day, China denied using lasers against aircraft in Dijibouti, calling them “groundless accusations.”

The current provider of the Air Force’s laser protection is Teledyne Scientific & Imaging, which was awarded a $30.1 million contract in July 2016 for 11.805 Aircrew Laser Eye Protection (ALEP) Block 2 glasses. The May 2 2018 RFP is for Block 3 glasses and visors. and will provide protection both during the day and at night from laser light.

The RFP’s Requirements Matrix does not specify the exact wavelengths to be blocked. It does say that the night version must have at least 50% visibility (Photopic Luminous Transmittance) and at least 14% for day versions. The document also states:

The ALEP Block 3 will not impair visual performance to the extent that it interferes with safety of flight or mission completion. The device will be visually compatible with the following devices/activities:
  • All USAF aircraft
  • Joint Helmet Mounted Cueing System (JHMCS); Night Vision Goggles (NVG); Panoramic Night Vision Goggles (PNVG), Helmet Mounted Integrated Targeting (HMIT/HoBiT), and fielded/post- Milestone B visors and aircrew chemical warfare masks
  • Canopies/windscreens, HUD, and color cockpit displays
  • Detection, recognition, identification, and tracking of targets
  • Ability to distinguish terrain colors and geographical features
  • Cockpit interior lighting, external aircraft lights, and airfield lights
  • Ability to read charts, maps, and other printed materials in the cockpit
  • Ability to perform normal aircraft duties in cockpit

Ukraine: Developing countermeasures after 4 cases of laser eye injury

The State Border Guard Service of Ukraine will find countermeasures against Russian laser weapons, Interior Minister of Ukraine Arsen Avakov said, according to a May 5 2018 Interfax-Ukraine report.

“We already had several such cases (a laser injury of the eye retina) in the State Border Guard Service and in the National Guard. We are now developing countermeasures. We do not fully understand what they use, but we are already working on the instructions what it could be. We will install the appropriate filters, devices, use appropriate glasses,” Avakov said.

He reported on four cases of the laser injury of border guards and national guardsmen.

“The use of such weapons is a barbarous situation. We will discuss it at the international level,” Avakov emphasized.

US: Utah National Guard reluctant to report laser cases to FBI, apparently after suspect's suicide

Utah National Guard pilots have not reported incidents where lasers were aimed at their aircraft since at least September 2009, according to an August 30 2017 news story in the South Valley (Utah) Journal.

In an interview, Chief Warrant Officer Robert Williams discusses the hazards of laser interference with pilots. He recounts an episode in mid-July 2017 where he and a co-pilot were lased. They identified the source of the laser beam. Ground officers found that the perpetrator was a teenager. Williams said “We specifically requested that the cops not get the FBI involved. I don’t want any kids going to jail or getting felony charges on their record.”

He added, “When the cop showed up at the door and explained to the dad what was going on, the dad broke the kid’s laser there on the spot.”

The reluctance to report appears to stem from a 2009 lasing incident which was reported to the FBI. A 30-year-old man, Joshua Don Park, “on a whim” decided to aim a cat laser pointer at a Utah National Guard helicopter. Park told arresting officers that he was unaware the laser’s light could interfere with pilots’ operations. The Journal story says Park “faced up to five years in prison. [Another source says he faced up to 20 years.] Tragically, he committed suicide shortly before he could be sentenced.”

The story continues, “Since that sobering incident, no Utah National Guard pilots have reported lasing incidents to the FBI—but not for lack of occurrences. ‘My unit alone has had two incidents in the past three months,’ said Williams.”

US: Navy tests green beam across Chesapeake Bay

The U.S. Navy announced that they would be testing a green laser across the width of the Chesapeake Bay in the evenings on June 26-30 2017.

The information was released to help reassure any residents who might see the beam. The Navy called the beam “eye-safe” and said the beam would be turned off if an aircraft or watercraft is within 300 meters.

The purpose of the test is to “evaluate the performance of a laser system at long range over water,” according to a spokesperson. The laser would be aimed from the source to a target as far as 13 miles away.

There was speculation that the laser was 150 kilowatts, based on an earlier speech by the vice chief of naval operations. However, the spokesperson said the June 27 test would not be using the 150 kW laser.

US: Anti-laser laser for drone defense

The cameras and sensors on drones can be disrupted by laser light. This is of special concern to the military.

To help defend drones against laser light, a California company has developed a defensive laser to be mounted on the drone. When it detects a laser attack, it first analyzes the incoming beam’s power, wavelength, pulse frequency and source. It then uses its own laser to counter the incoming beam.

The exact method is secret. New Scientist speculates “…it may involve fooling the control system into thinking it is hitting its target despite the laser actually pointing a few metres to the side. A direct hit would have produced a big burst of reflected light, so a pulse sent back by an anti-laser laser could make it look like the original laser was on target.”

The company is Adsys Controls of Irvine, California; the anti-laser laser system is called Helios. According to the company, “Helios is a low SWaP [Space, Weight and Power], completely passive Counter Directed Energy Weapon system capable of nullifying the enemy’s DEW [Directed Energy Weapon]. Consisting of a small UAV-mounted sensor package, Helios provides full analysis of the incoming DEW beam including localization and intensity. With this information it passively jams the enemy, protecting the vehicle and the payload.”

Israel: Lasers on airplanes used to deflect missiles

Israel will begin equipping commercial aircraft with lasers to deflect incoming missiles. The C-MUSIC (Commercial MUlti-Spectral Infrared Countermeasure) system uses infrared sensors to automatically detect missiles fired towards the plane. A laser is then aimed at the missile’s navigation system to deflect it off course where it will explode and not harm the aircraft.

The system was developed after a 2002 incident in Kenya where terrorists fired two surface-to-air missiles at an Israeli charter plane carrying more than 250 passengers; the missiles missed their target. C-MUSIC will be added to all El Al aircraft. In addition, the developer Elbit Systems has contracts with other countries besides Israel.

US: Laser aimed from aircraft to ground results in dozens of calls

An airplane flying around Honolulu and other parts of Oahu, shining a green laser onto residents, is actually mapping Hawaii using LIDAR (LIght Detection And Ranging). The mapping normally is done during daylight hours but was moved to nighttime due to FAA flight restrictions.

In a September 16 2013 article, HawaiiNewsNow said there were “dozens” of inquiries about the nighttime green light. One person emailed that the aircraft circled his area about six times at 1:00 am, with a wide green laser that appeared to be scanning downward. Another email confirmed the multiple passes with a V-shaped green laser.

The Army Corps of Engineers is conducting the work. They stated that the laser is not harmful to the eyes. The Oahu work should take about a week, and mapping the entire state should conclude in November.

From HawaiiNewsNow. Similar flyovers using visible green lasers have occurred in other U.S. cities, such as New York City in 2010 and 2012, according to a a brief Google search of such reports, for example here and the comments here.

US: $208 million contract to protect Army helicopters from laser threats

The U.S. Army on August 26 2013 awarded a $208.5 million multi-year contract to UT Aerospace Systems ISR in Danbury, Conn. for a passive laser warning system to detect analyze and display threat information when a helicopter is illuminated by lasers. The flight crew is directed on how to take evasive action. The laser threats can be from weapons that use lasers for designation and range finding, and from blinding lasers.

The Army/Navy Piloted Aircraft/Visual and Visible Light/Receiving, Passive Detecting (AN/AVR-2B) Laser Detecting Sets (LDS) uses four sensor units placed on the aircraft. It is smaller, lighter and uses less power than a previous generation developed for the cancelled Comanche helicopter program.

News reports did not state how much it costs to equip each helicopter with an AN/AVR-2B system.

US: 198 calls to police about lasers in 3 months; Coast Guard "cracking down" in Myrtle Beach

Despite anti-laser pointer ordinances in Myrtle Beach, South Carolina, police have responded to 198 reports of laser misuse between May 1 and July 31 2012. A police spokesperson said this keeps police away from other, more important business. He said one problem is informing the many visitors about Myrtle Beach’s restrictions. For example, anyone shining a laser at persons or aircraft can be charged with a misdemeanor.

The local Coast Guard echoes the concerns. Twice in two weeks, search and rescue missions were ended prematurely because of lasers being aimed at helicopters. (See a report here.) Under Coast Guard regulations, after laser exposure the aircraft is grounded and the pilots are medically evaluated before being allowed to fly again.

The Coast Guard issued a letter asking the public to stop aiming at aircraft, and saying that they want to enforce South Carolina’s state law against lading aircraft. The letter is reprinted below (click the “Read More” link).

Worldwide: Laser weapons 10-20 years away from widespread deployment

Lasers and other directed electromagnetic weapons won’t be widely deployed until the 2022-2032 time frame, according to experts speaking at a conference on Direct Energy Systems.

One speaker noted “…we have had kinetic weapons for 500 years and laser weapons for 10-15 years…. The soldier wants a reliable, easy-to-handle, clear to understand system that has the reliability of a normal M16 rifle, or whatever, therefore the superiority is on the kinetic side.”

General interest: Article discusses pros and cons of laser sights for weapons

An interesting article at Officer.com describes how laser sights can be used to enhance firearm proficiency. According to the article, laser sights help in training and simulation, allow faster target acquisition, “help minimize collateral damage, reduce tunnel vision and allow proper use of cover and/or concealment.”

Author John Wills notes that laser sights are not as effective beyond 20 feet, and they do not substitute for marksmanship techniques such as grip and stance.

Green laser sights are now available; they are more easily seen than an equivalent-power red laser. Infrared laser sights are made for use with night vision goggles. The beam cannot be seen by the naked eye, so a bad guy does not even know he is being targeted.

Wills concludes by saying “like any other tool there is a right way and a wrong way to use” lasers.

US: Airborne missile-killing laser project mothballed after $5 billion

After 16 years and $5 billion in development, the U.S. Air Force’s Airborne Laser Testbed (ABL) program has been shut down. An entire Boeing 747 was needed to house the chemical oxygen iodine gas laser. The COIL laser generates megawatts of power, enough to damage missile skins thus causing the missile to disintegrate. In 2010 the ABL was used against solid- and liquid-fueled rockets in tests.

Pic 2011-12-27 at 11.28.43 AM
Cockpit view of the ABL shooting down a missile on Feb. 11 2010. Video is
here.


A key reason for the ABL shutdown was the cost of the project versus the projected military returns. Another reason is that the Missile Defense Agency is looking to a new generation of laser systems with “much denser capacity or greater power lasers in smaller packages and operating at much higher altitudes.” Unmanned aerial vehicles would be an ideal platform. The MDA’s director said antimissile drones using solid-state lasers could be a reality by 2020.

From Aviation Week. An analysis of laser weapons is at Strategy Page.

Commentary from LaserPointerSafety.com: We included this story because people sometimes wonder if lasers aimed from the ground can damage an aircraft’s airframe. The short answer is “no”. It would take a system similar to the $5 billion ABL. However, the Missile Defense Agency is now indicating that military-developed solid-state lasers may be able to cause enough damage to down a missile -- or aircraft -- within this decade (the 2010s).

While it is unlikely that non-state groups could deploy such a device, it is more of a possibility than independently developing an ABL-like COIL gas laser. For the foreseeable future, the threat to aircraft remains the visual impairment caused by bright laser light, and to a lesser degree, the possibility of causing retinal lesion eye injuries.

Concept of the rifle, from the Daily Mail


The developer is Photonic Security Systems, which also markets the rifle as a pirate deterrent. The Telegraph says that similar devices have been used in Afghanistan by NATO-led International Security Assistance Force troops.

PSS managing director Paul Kerr told the International Business Times "The very purpose of this technology is to be non-damaging … If someone is prepared to just stand there and stare down the barrel at this, which would be incredibly uncomfortable, then they are definitely a threat.” He said that he has often been exposed to the laser: "The quality and safety of the device is paramount and I know that first hand because I have been the guinea pig many times. I know what it is like and I know how effective it can be."

Author and activist Cory Doctorow points out that “the UK is a signatory on the Protocol on Blinding Laser Weapons … this weapon wouldn’t run afoul of international law if it (merely) reduced your vision to the point where you were impaired but not legally blind, permanently.” Doctorow also says “Twitter wags are already predicting a resurgence of mirrorshades [reflective sunglasses] among protesters.”

US: Military helicopters may use lasers to fight ground-based attacks

U.S. military helicopters may use lasers to dazzle ground-based attackers firing small arms and rocket-propelled grenades. There are two components to the system: detection and laser countermeasures.

Black Hawk and Chinook helicopters have been testing a acoustic detection system called “Helicopter Alert and Threat Termination”, or HALTT. This uses microphones to detect the sound of a bullet or RPG. Delays in the sound reaching the microphones enables them to determine the sound’s location. A similar truck-mounted system is already in use. It can automatically swivel and fire a gun in the direction of the sound.

For helicopters, HALTT can be combined with guns and/or lasers. Infrared lasers help confuse missile guidance systems, while visible lasers would dazzle and flashblind anyone aiming at the helicopter. An engineer said the principle is to “make it impossible for a human to observe your aircraft … by creating a distracting light source. That has been done in the past and is a proven technology…”. The HALTT/laser countermeasure system could be in use by 2017.

The military already uses laser dazzlers at checkpoints, to warn approaching vehicles and to cause glare on anyone taking aim at soldiers.
