The U.S. military needs to better protect its satellites and strengthen its ability to use them as weapons as the uncharted battlefield of space becomes increasingly crowded and dangerous, Pentagon leaders say.
A new military strategy for space, as mapped out by the Pentagon, calls for greater co-operation with other nations on space-based programs to improve America’s ability to deter enemies.
“It’s a domain, like air, land and sea,” said Gen. Kevin Chilton, who led U.S. Strategic Command until he retired late last month. “Space is not just a convenience. It’s become a critical part in every other (battlefield) domain.”
The U.S., Chilton said, needs to make sure that it protects and maintains the battlefield capabilities it gets from space-based assets, including global positioning data, missile warning system information, and communications with fighters or unmanned drones that are providing surveillance or firing missiles against the enemy.
As the U.S. and other countries depend more on their satellites for critical data, those assets become greater targets for their enemies.
“It’s prudent to anticipate that, at this point, we will not go into a future conflict with a sophisticated adversary and not expect to be challenged in the space domain,” Chilton told The Associated Press in an interview. “We need to be thinking about how we would go into future conflicts and make sure that we un-level (that) battlefield in our favour.”
While the new strategy — the first of its kind — stresses the peaceful use of space, it also underscores the importance of satellites in both waging and deterring war.
“We need to ensure that we can continue to utilize space to navigate with accuracy, to communicate with certainty, to strike with precision and to see the battlefield with clarity,” said William Lynn, deputy defence secretary.
Lynn and other Pentagon leaders say space has become more congested, competitive and contested, and the U.S. needs to keep pace on all fronts.
Gen. James Cartwright, vice chairman of the Joint Chiefs of Staff, said the U.S. and other nations must develop rules of the road for space that lay out what is acceptable behaviour and movement there.
At a forum put on by the Center for Strategic and International Studies, Cartwright said nations need to have guidelines that govern the approximately 22,000 manmade objects orbiting earth, including about 1,100 active satellites.
For example, he said, there is nothing that requires objects to pass left to left, or that says which country should move its satellite if two objects are on a collision course.
While avoiding crashes is an important goal, officials said nations also need to ensure that their communications and other signals passing through the satellites also do not conflict.
The strategy offers little detail about offensive operations in space. But defence officials say that China, Iran and others have demonstrated their abilities to take action in space.
In January 2007, China startled world leaders when it took out a defunct weather satellite with a warhead launched on board a ballistic missile.
China’s actions made it the first country to destroy a satellite with a ground-based missile. The U.S. and Russia had shot down satellites, but the U.S. did it in 1985 with an air-launched missile and the Soviets with a hunter satellite.
The China shoot-down alarmed officials, who said it signalled the launch of space wars and would set off a race to militarize space.
According to James Lewis, a national security expert at the Center for Strategic and International Affairs, an attack against U.S. satellites can immediately degrade military performance, taking out communications, data links and other networks needed to operate weapons, sensors and fighters in the air.
“We need some kind of understanding among spacefaring nations about what we can and can’t do,” Lewis said, adding that a key is to have layers of defence, so there are backups if one set of signals is lost.
The new space strategy, endorsed by top Pentagon and intelligence officials, also shows the importance of having alternatives. For example, if a satellite signal is being jammed, officials should be able to go to another or to an air or sea-based signal.
The U.S. also needs to make it known that even if another nation attacks an American satellite, the U.S. military response wouldn’t be limited to a space-based action, officials said. It could turn to any of its warfighting capabilities.
