During a recent trip to Yuma Proving Ground, in Arizona, I passed a unique looking artillery piece in a remote area of the installation. It has an extremely long barrel and appeared to be anchored in a concrete abutment. Having more than a passing interest in ordnance I made some inquiries as to origins and purpose of the gun.

The brainchild of Jerry Bull (of “Iranian Super...

U.S. Air Force is concerned about American dependence on space satellites, particularly the GPS birds. The air force believes China is developing the ability to carry out a major attack on American military satellites. Their proposed solution is to take GPS out of orbit, and make it portable. High flying aircraft, UAVs or blimps would take over satellite communications, surveillance and navigation (GPS) chores, although for smaller areas. This would make GPS, and other satellite functions, more resilient to attack. This is part of a trend in which military satellites are getting priced out of the market by cheaper manned...

The US military is relying ever more on space satellites to help wage combat in places like Iraq and Afghanistan, though analysts say that Washington's space supremacy could be threatened by rivals in the future. The Pentagon is using sophisticated satellites that orbit Earth in a bid to track down its enemies and keep a round-the-clock watch on unfriendly foes. The technological advantage can prove lethal, as witnessed by the recent air raid that killed the long-wanted Al-Qaeda in Iraq leader Abu Musab al-Zarqawi. "Space capabilities have revolutionized the way we fight today by providing our forces with battlefield situational...
