I really want to ask Loren Thompson exactly what level he would stoop to in his efforts to advocate Air Force acquisition programs. How much would he ignore in his protestations that OSD is not giving struggling program offices a chance to mature their technologies? Well, now I know. He wrote to the National Defense magazine in an effort to combat what he saw as "bad press" when that journal critically reviewed the Airborne Laser (ABL) program. Here's what was stated by Grace Jean in the March article:
Just a year ago, the Pentagon’s science advisors warned that a lack of progress in the development of directed-energy weapons has resulted in a significant decline in interest and support for these technologies. The panel of advisors, known as the Defense Science Board, pointed out that not a single directed energy system has been fielded to date, and that there are fewer programs currently under way than there were a decade ago.
One of the toughest technical challenges is producing lasers with enough lethal energy to surpass conventionally powered weapons, says Philip Coyle, a senior advisor at the Center for Defense Information and a former director of weapons testing at the Pentagon. “It’s really hard to beat the amount of energy in a rifle bullet, let alone even more powerful weapons systems,” he says. To do so with a laser requires a large and heavy system that is not conducive to the rigors of the battlefield.
Military laboratories and contractors have spent decades trying to boost the power in laser systems while trying to pare down the package, with limited success.
“It’s not easy and nobody has really succeeded yet,” says Coyle.
Despite limited gains and successes, the program still has not convinced members of Congress or OSD leaders that this is a viable and operational capability that should be further funded. And when we say funded, it has already had $4.3 billion poured into the effort. Thompson leaps to the defense:
While lasers are not always a cost-effective alternative to conventional “kinetic” weapons, they are distinctly unique. They deliver lethal energy at the speed of light — about 300,000 kilometers per second — and are not subject to physical constraints such as gravity and atmospheric drag. In many applications they cost much less per kill than using missiles or munitions. They also are more precise and more versatile than other weapons. For instance, depending on power levels, the same laser device can be used to destroy a target, nonlethally disable it, or simply track it.
The performance of the airborne laser program needs to be understood against this backdrop. It is true that the program has been delayed several years by technical challenges, and that it consumes more funding than all of the government’s other directed-energy weapons programs combined. But it has made steady progress toward operational status, and will provide revolutionary capabilities when it gets there.

It may turn out to be the only weapon that can successfully destroy ballistic missiles headed for the United States before they release multiple warheads and penetration aids. If the system achieves successful shoot-down of a live target this year it is a huge breakthrough, and if it doesn’t then it deserves to be tested a second time. It doesn’t make sense to spend 15 years and $4.3 billion on a vital capability, and then throw it all away because of one failed test.
Thompson uses Edison's search for a durable light bulb and the development of the Internet as similar examples of how research and development efforts took time to show their true potential. But those are inappropriate examples, not only because the federal government didn't pour billions into those programs. Just because we can put a large, expensive chemical laser in the sky does not mean that it ought to be developed as a military capability. For the ABL to be successful, it basically has to be flying near the launch point of the ballistic missile to catch it during the boost phase. So do the math - for every nuclear-owning weapon state, we have to have a number of Boeing 747s flying loops around that state, waiting for the launch to occur. Does this sound like a reasonable operational concept?
Thompson gets quoted heavily in major news papers in addition to writing frequently on Air Force (and other defense) topics for his think tank, the Lexington Institute. His advocacy goes a step too far when he ignores the substantial cost of research and development to date, the lack of a sound operational concept, and competing defense requirements during wartime. President Obama and SecDef Gates were right to push this program back into early R&D. Had I been within earshot of those two, I would have pushed for killing it entirely - but Congress probably wouldn't have allowed that to happen.
