Shape of things to comeBoeing successfully tests airborne tactical laser

Published 2 September 2009

Silent death ray from the skies may usher in a new chapter in warfare: the laser may cause a cell tower to stop working, a vehicle’s fuel tank to suddenly explode, or a single person to inexplicably be incinerated — all completely silently and tracelessly, without anyone knowing they were ever there and not so much as a spent bullet left behind

Boeing has announced a long-delayed in-flight firing for the smaller of its two airplane raygun-cannon prototypes, the Advanced Tactical Laser (ATL). In tests, the ATL blaster, mounted in a Hercules transport aircraft, “defeated” an unoccupied stationary vehicle. “This milestone demonstrates that directed energy weapon systems will transform the battlespace and save lives,” said Boeing exec Greg Hyslop. “The ATL team has earned a distinguished place in the history of weapon system development.”

The bottom line is that ATL works, and works very well,” added Gary Fitzmire, vice president and program director of Boeing Missile Defense Systems’ Directed Energy Systems unit.

Lewis Page writes that the ATL is much smaller than Boeing’s headlining laser weapon, the jumbo-jet-mounted Airborne Laser (ABL), intended to blast enemy ICBMs as they soar upward from pad or silo. Rather, the ATL is intended to pick off individual ground targets, somewhat in the fashion of existing Hercules-based side-firing AC-130 gunships. Indeed Boeing has referred to the ATL in the past as its “Laser Gunship.”

ATL does resemble the ABL in some important respects, however. Like the bigger weapon, it is a chemically fueled laser rather than a solid-state electrically powered one, meaning that it can fire only a limited number of blasts before its sealed, six-ton laser module must be maintained and refueled with hazardous toxic chemicals.

Page says that just how many shots the ATL can fire before being rearmed is unclear, but hints dropped by Pentagon sources suggest it could be as few as six. This compares poorly with the firepower available aboard a normal AC-130, leading some analysts to wonder what the point of the ATL really is.

Boeing say that it will offer “ultra-precision” and “dramatically reduce collateral damage”, though so far nothing of this sort has really been shown. A 40mm cannon aboard a normal AC-130 could “defeat” a stationary ground vehicle without damaging its surroundings: a .50-cal sniper rifle fired from a helicopter could do the same to a moving one.

It has not escaped notice, however, that neither of those things could strike silently — perhaps from so far off that the carrying aircraft would not be noticed, either — and without leaving any solid evidence of U.S. military presence. Nor have observers failed to note that the U.S. military agency in charge of ATL is the secretive Special Operations Command (SOCOM).

Boeing has evidently had some problems with the ATL — airborne test firings were expected last year, but this success didn’t happen until last Sunday.

It would seem, though, that the system may soon be as ready for front-line use as it will ever be, at least until electric lasers without fuel limitations are weaponized.

In years to come, the secret supertroopers of SOCOM may be able to cause a cell tower to stop working, a vehicle’s fuel tank to suddenly explode, or a single person to inexplicably be incinerated — all completely silently and tracelessly, without anyone knowing they were ever there and not so much as a spent bullet left behind,” Page concludes.
