Small unmanned spacecraft is set for launch

The Air Force hasn’t revealed much about its X-37 pilotless space plane, fueling speculation that it’s being developed for military purposes.

It may seem like a harmless, miniature version of the space shuttle, but some industry analysts are wondering if the secretive robotic spacecraft set to launch Thursday from Cape Canaveral has a more sinister side.

“Are we looking at a new space vehicle or an orbital bomber that’s capable of attacking from space?” said John Pike, director of, a website for military policy research. “At this point, it’s hard to say.”

The U.S. Air Force, which has been developing the X-37 pilotless space plane, isn’t saying much. Even the launch has been kept out of the public eye, and only Pentagon-sanctioned photographers can take pictures of the vehicle.

The program isn’t entirely classified. The Air Force revealed that it’s about 29 feet long, or about the size of a small school bus, with stubby wings that stretch out about 15 feet. It is one-fifth the size of the space shuttle and can draw on the sun for electricity using unfolding solar panels.

It is the latest version of a spacecraft that initially began more than a decade ago as a NASA program to test new technologies for the space shuttle. When President George W. Bush decided to retire the space shuttle, the Pentagon took over the program and shrouded its development in secrecy.

The Pentagon won’t say how much it has spent on the space plane or what its ultimate purpose may be. It has been equally cryptic about when the spacecraft would return to Earth. The space plane is designed to be launched atop an Atlas V rocket and then land on its own at Vandenberg Air Force Base.

“In all honesty, we don’t know when it’s coming back,” said Gary E. Payton, deputy undersecretary for Air Force space programs, in a conference call this week. He did say that the vehicle can stay in space for up to nine months.

Air Force officials also deflected questions about using the X-37 for military missions, saying that the spacecraft is simply a way to test new technologies, such as satellite sensors and components.

But analysts question whether the Pentagon would be willing to spend possibly hundreds of millions of dollars for an orbiting laboratory at a time when the government is tightening spending.

“It wouldn’t be in the defense budget if it didn’t have defense capabilities,” said Pike of “The idea of a small-winged vehicle that can go into orbit and perform military missions has been around for half a century.”

Analysts said the program seems similar to the 1960s effort by the Air Force to develop the X-20 Dyna-Soar, a reusable space plane that could be used to knock out foreign satellites as well as conduct reconnaissance and bombing missions. After numerous problems, it was canceled in 1963.

The X-37 could be a descendant of the Dyna-Soar program, said Paul H. Nisbet, an aerospace analyst with JSA Research Inc. in Sarasota, Fla. “But it looks like the program is purely experimental right now,” he said.

Air Force Lt. Col. Troy Giese, X-37 systems program director, said the space plane has no offensive capabilities and he did not want to speculate about its future capabilities. For now he just wants to see it fly.

“Much like testing a new aircraft, it’s a check flight to prove everything works properly,” he said.

One thing is certain. Built by Boeing Co.’s advanced research lab, Phantom Works, in Huntington Beach, the X-37 would be the first U.S. unmanned spacecraft to be launched into space and land on its own.

If the X-37 does make a successful reentry and touch down, it will mark another first. The 15,000-foot landing strip at Vandenberg was built to accommodate the space shuttle but was never used for it.

The Air Force already has an order for another X-37 from Boeing, Giese said. The second flight could take place in 2011, but he said “much of that depends on the initial test program.”
