Laser System Targets Short-range Aerial Threats: Lockheed Martin has demonstrated a portable, ground-based laser system called ADAM in a series of tests against rockets and remotely piloted aircraft, announced the company on Nov. 27. ADAM stands for Area Defense Anti-Munitions system; the 10-kilowatt fiber laser is designed to bring down short-range aerial threats, states the company's release. Since August, ADAM has successfully engaged an RPA in flight at a range of nearly a mile and has destroyed four small-caliber rockets in simulated flight at a range of about 1.2 miles, according to the release. "Lockheed Martin has applied its expertise as a laser weapon system integrator to provide a practical and affordable defense against serious threats to military forces and installations," said Paul Shattuck, the company's director of directed energy systems for strategic and missile defense purposes. ADAM, which incorporates some commercial hardware, has a tracking range of more than three miles and can engage RPA with an external radar cue, according to the company.View RSS feed

TITLE: Low-Observable Heat Rejection from Aircraft
 
TECHNOLOGY AREAS: Weapons
 
The technology within this topic is restricted under the International Traffic in Arms Regulation (ITAR), which controls the export and import of defense-related material and services. Offerors must disclose any proposed use of foreign nationals, their country of origin, and what tasks each would accomplish in the statement of work in accordance with section 5.4.c.(8) of the solicitation.
 
OBJECTIVE:  Future aircraft-based high energy lasers will produce hundreds of kilowatts of low-quality waste heat. Novel approaches are sought to remove waste heat under these conditions without significant impact on aircraft signature/aerodynamic performance.
 
DESCRIPTION:  The large quantities of low-quality (<40C) waste heat generated by directed energy and other electrically based technologies need to be removed from air platforms in a manner that will allow the system to meet size, weight and power constraints and not interfere with aircraft operation. Heat from directed energy systems is often generated in laser diodes with junction temperatures from 20C-30C as required for the desired pump laser wavelength. Most laser diode packages require non-electrically conductive working fluid with the current state of the art being de-ionized water which is undesirable for airborne logistics reasons.  Due to the high peak heat flux of laser systems (~1MW), thermal storage is often used during system firing and a smaller, steady heat sink will recharge the thermal storage. The heat removal capacity of fuel as working fluid is at or near its capacity in future and current air platforms. Heat sinks are being sought that do not involve transferring heat to the fuel.  Non-fuel heat sinks have the potential to add to the aircraft thermal signature, radar cross section or adversely impact the aerodynamic performance of the platform.  The successful proposal will investigate heat sinks which do not significantly impact the thermal signature, radar cross section or the aerodynamic performance of sub and transonic aircraft and which have the capacity to continuously remove up to 100kW of heat at less than <40C at altitudes from 10kft to 40kft.

ONR Developing Air-Defense Laser Gun As Possible Stinger Replacement   The Marine Corps and the Office of Naval Research are working to develop a laser weapon system that would fit on a tactical vehicle and provide ground-based air defense for troops and convoys against threats ranging from small unmanned aerial vehicles to missiles and manned aircraft.

Depends....  How far away is the target?  How long does the laser have to burn said target?  What sort of atmospheric conditions does the laser have to burn through?

I heard on another site that either the Air Force or Navy are doing/did a research paper on the physchological implications of laser weapons on both friendly and enemy personnel and non-combatants. Does anyone know of this or possibly have a link to the thesis?

Thank you sir, great find...another reason even small helios gotta get bigger..no survival w/o DEW i the future.
