Recent releases of previously classified information is now giving us exciting looks into the future beam weapons under consideration, or in some cases, under construction.

We have also taken a little time to dig up some interesting white papers on the subject of lasers and their relationship to space based weaponry from the U.S. Air Force's War College (Occasional Papers) section:

MILNET presents a summary of current information on these:

Updates:

03/02/2007:  A report written by John McHale, for Sander Research highlights a number of high energy laser projects in the works, moving the use of lasers for military applications from the theoretical to practical stages. 

Program Name
Description
Progress
Joint High-Power Solid-State Laser -- JHPSSL A
Technology Program intended to "incorporate high-energy laser systems across all services, including ships, manned and unmanned aircraft, and ground vehicles" A

"The initial goal is to develop a solid-state laser weapon capable of generating 100,000 watts, or 100 kilowatts."

Northrop Grumman Corp. was awarded the $56.7 million prime contract for the Pentagon's major solid-state laser weapon push, the Joint High Power Solid-State Laser program.   B
?
Tactical High-Energy Laser Utility Study -- THELUS A Simulation study that pits fighter pilots against overwhelming odds, then adds the capability of a DEW (Directed Energy Weapon) to the mix.  "To determine the DEW’s effects on the mission, the researchers altered two distinct characteristics of the DEW throughout the test scenarios, changing the maximum sensor range (which determines how far pilots can see with the DEW) and the thermal budget (which determines how long pilots can fire continuously)."  The study is under the auspices of the Tactical High Energy Laser -- THEL -- program.
shows DEW enabled aircraft have a much higher survivability rate.
Airborne Laser --
ABL A
Designed to attack ballistic missiles in the boost phase, destroying them over the agressors own land, using an extremely high powered laser mounted in a highly modified Boeing 747-400F airframe with nose turrent and two smaller lasers for aiming and determining atmospheric conditions on the beam. The attacking laser is a chemical laser which has been tested on the ground at attack levels and for durations required in order to deliver its knockout punch.
Aircraft began flight testing in 2006, while ground testing of the full power laser has been completed.  Optics for the full power weapon have also been tested and are being readied for a full power flight firing.  Surrogate solid state lasers are scheduled for initial flight testing of the guidance, tracking, and metrics on board the aircraft, and later the "real deal" will be added for full up system testing.
Advanced Tactical Laser --
ATL A
An Army laser gunship project which uses a extremely high power chemical laser to attack targets on the battlefield.   The current aircraft chosen is a C-130 (the AC-130 gunship perhaps?) using a firing bubble on the underside of the aircraft, and in which the beam director can be used to illuminate any targets visible and within range of the laser's lethal radius.  The precision of the battlefield system is expected to be able to attack specific areas on targeted vehicles or facilities -- making it possible to shoot out a tire to immobilize or target the gas tank to create an explosion and destroy the vehicle.  Development is through an Army ACTD (Advanced Concept Technology Demonstration) program.
Flight testing has begun, and will shortly use a surrogate solid state laser to test the support systems prior to flight tests with the full up attack laser
Skyguard A System from Northrup-Grumman that proposes a "laser-based air defense system for U.S. government agencies and allies that require near-term defense against short-range ballistic missiles, short- and long-range rockets, artillery shells, mortars, unmanned aerial vehicles and cruise missiles.."  It is based upon the successful Tactical High Energy Laser -- THEL -- prototype.   The new system will provide more power and in half the size of the previous test bed.  The new system will be moved in three 20X8 foot containers and setup within hours.  THEL has been in continous use since its development shots in 1990.  "“This test bed has been remarkably successful. To date, it has shot down dozens of live threats, including long- and short-range rockets, mortars, and artillery projectiles, in very realistic attack scenarios, and under simulated operational conditions such as surprise attacks and mixed threats."  THEL was derived from a FY96 Advanced Concept Technology Development (ACTD) program.
Early development, no details on actual testing, however makes use of technology derived from the THEL program, perhaps giving it a boosted time to field development time.
Laser Area Defense System --
LADS B
A losing bid has not dettered Raytheon from continiuing the program, the company betting the technology is quite viable and will result in future technology improvements that will make for a winning bid in the future.  LADS uses a solid state laser adapted to the PHALANX ship board ship's defense system, "We already know our Phalanx system can see something the size of a mortar and track it".

"LADS could compete with "C-RAM" — Counter Rocket, Artillery Mortar — systems designed to track and destroy incoming projectiles with explosive bullets, said John Pike, director of GlobalSecurity.org.

"The problem is, when the bullets go up, they tend to come down," possibly endangering troops or civilians, Pike said."


Has "detonated stationary 60 mm mortars at a range of more than 550 yards in recent ground testing"

"
Raytheon developed the LADS on its own dime in six months, using "an existing, off-the-shelf solid-state laser, coupled with commercially available optics technology"
