The Senate just drove a stake into the Navy’s high-tech heart. The directed energy and electromagnetic weapons intended to protect the surface ships of the future? Terminated.
The Free Electron Laser and the Electromagnetic Rail Gun are experimental weapons that the Navy hope will one day burn missiles careening toward their ships out of the sky and fire bullets at hypersonic speeds at targets thousands of miles away. Neither will be ready until at least the 2020s, the Navy estimates. But the Senate Armed Services Committee has a better delivery date in mind: never.
The committee approved its version of the fiscal 2012 defense authorization bill on Friday, priced to move at $664.5 billion, some $6.4 billion less than what the Obama administration wanted. The bill “terminates” the Free Electron Laser and the rail gun, a summary released by the committee gleefully reports.
“The determination was that the Free Electron Laser has the highest technical risk in terms of being ultimately able to field on a ship, so we thought the Navy could better concentrate on other laser programs,” explains Rick DeBobes, the chief of staff for the committee. “With the Electromagnetic Rail Gun, the committee felt the technical challenges to developing and fielding the weapon would be daunting, particularly [related to] the power required and the barrel of the gun having limited life.”
Both weapons are apples in the eye of the Office of Naval Research, the mad scientists of the Navy. “We’re fast approaching the limits of our ability to hit maneuvering pieces of metal in the sky with other maneuvering pieces of metal,” its leader, Rear Adm. Nevin Carr, told me in February. The answer, he thinks, is hypersonics and directed energy weapons, hastening “the end of the dominance of the missile,” Adm. Gary Roughead, the top officer in the Navy, told me last month. With China developing carrier-killer missiles and smaller missiles proliferating widely, both weapons would allow the Navy to blunt the missile threat and attack adversaries from vast distances.
And both have recently experienced technical milestones that made researchers squeal with glee.
In December, the Navy corralled reporters to Dahlgren, Virginia, to watch a rail gun the size of a schoolbus fire a 23-pound bullet using no moving parts — just 33 megajoules of energy, a world record. (A prototype of a ship-ready rail gun is pictured above.)
And this winter, the Free Electron Laser, the most powerful and sophisticated laser there is, boasted two big advances within a month. In January, its 14-kilowatt prototype passed tests that injected enough energy into it to get it up to a megawatt’s worth of death ray — a “remarkable breakthrough,” nine months ahead of schedule, the Office of Naval Research crowed. The next month, its testers at the Jefferson Lab in Newport News added even more power. Researchers think it could be far more than a weapon: it might act as a super-sensor, and Yale scientists use it to hunt for cosmic energy.
Shipboard power is the question mark surrounding both weapons. The laser and the rail gun require diverting power from a ship’s generators in order to fire. The Navy’s waved that away, saying that its onboard generators — especially the superpowerful ones in development — can handle the megawattage necessary, and the Free Electron Laser’s guts are shaped like a racetrack to “recycle” some of the energy injected into it. But both plans rely on the power efficiency of ships that aren’t built yet.
Neither comes cheap, either. The Navy’s spent some $211 million since 2005 developing the rail gun. Its milestones with the Free Electron Laser — in development in some form since the ’90s — led it to ask Congress for $60 million in annual directed-energy research funds, most of which go to the superlaser. Needless to say, a Senate panel facing a huge budget crunch was unsympathetic.
The Office of Naval Research didn’t respond by press time. The process of passing a defense budget making it through no fewer than four committees and two floor votes, so it’s not like these programs cease to exist. But unless the Navy makes a big push for its futuristic weapons, both of them will die on the drawing board.

US senate cutting weapon development. I'm impressed.
But I doubt you were shedding any tears over millions of jobless Russkies who were making weapons for the Soviet Union (or, for a more extreme example, over the millions of Nazis who were making weapons for the Reich) - so them's the cards. When you start shedding
