The 2007 Air Force budget request allots $315 million to the Global Positioning System Block III satellite program, which is to offer higher anti-jam capabilities and improved accuracy and availability and integrity, as well as the capability to deny adversary use. The first launch for GPS III is slated for 2013. The 2007 dollars would fund a development contract for the spacecraft and a modernized ground segment.
BAE Systems has received a contract from Lockheed Martin to install an upgraded Block 4 electronic warfare system into new F-35 Joint Strike Fighters, as well as to retrofit some older jets.
