Speaking Wednesday at a Washington, D.C., conference, Gen. Norton Schwartz, Air Force Chief of Staff, said that the US military and its allies must be able to operate in a GPS-denied environment. The efforts by adversaries to jam or otherwise prohibit use of the position-navigation-timing data provided by the USAF-operated Global Positioning System satellites will only increase. However, having said that, Schwartz maintained that there is no intent to move USAF out of the GPS business. He called such a move “unlikely.”
The U.S. began extensive air and artillery strikes against Islamic State group targets in Syria on Dec. 19 in retaliation for the killing of three Americans on Dec. 13 by a gunman affiliated with ISIS, U.S. officials said.
