The U.S. Air Force’s RQ-4B Global Hawk is among 16 acquisition programs that experienced problems during early testing last year that need to be corrected, according to the Pentagon’s Office of the Director, Operational Test and Evaluation (DOT&E).
Introduced in 1999, the Saab Giraffe AMB (agile multi-beam) 3D radar has become one of the world’s leading multirole air defense radars. Derived from the earlier G40 and G75 mechanically scanned radars, the AMB has an active electronically scanned antenna that provides a range of around 75 miles and altitude capability of more than 60,000 feet. The antenna rotates once every second to provide full 360-degree coverage, and in its current version provides detection from surface level up to an elevation of 70 degrees.
American defense contractors are set to enjoy revenues of nearly $4.7 billion from Iraq, according to a series of arms sales notifications by the Pentagon to Congress in the past two weeks. The potential sales include an integrated air defense system worth $2.4 billion and 30 Bell 412EP helicopters worth $300 million. The deals include training and support.
In the wake of the Euro Hawk cancellation in Germany, the future of the NATO Alliance Ground Surveillance (AGS) system based on the similar Northrop Grumman Global Hawk UAV is in doubt. Germany intends to offer for AGS whatever alternative platform it decides to employ for the Cassidian integrated signals intelligence system (ISIS) that was the payload on the Euro Hawk. The Royal Air Force Raytheon Sentinel R.1 ground surveillance aircraft is also on offer.
A long list of major U.S. aerospace and missile defense systems that have been compromised by hackers was obtained by The Washington Post. The list was withheld from the publicly released version of a Defense Science Board Task Force report to the Pentagon on cyber threats last January. The report concluded that “the DOD is not prepared to defend against this threat.” According to senior industry and military officials contacted by the newpaper, most of the hacking was done by China.
The German Ministry of Defence abruptly canceled plans to introduce a fleet of five Northrop Grumman RQ-4E Euro Hawk UAVs for high-altitude Sigint collection. The first aircraft, delivered in July 2011, was already flying on development tasks from Manching airbase near Munich. According to German media reports, the country has already spent €508 million of the planned €1.2 billion (in 2012 prices) to acquire the fleet, which was intended to replace aging Atlantic manned twin turboprops.
Germany’s Federal Ministry of Defense (MoD) as a cost-cutting measure will not buy four production models of the RQ-4E Euro Hawk unmanned aircraft system as planned. The MoD’s decision to stop the program after acquiring one demonstrator aircraft was disclosed earlier this week. During a parliamentary debate, Defense Minister Thomas de Maiziere said of the decision: “We prefer to pull the plug.
The U.S. has made a formal offer to Korea of four Northrop Grumman RQ-4 Global Hawk Block 30 UAVs, in a package valued at $1.2 billion. The notification to Congress states, “The Republic of Korea needs this intelligence and surveillance capability to assume primary responsibility for intelligence-gathering from the U.S.-led Combined Forces Command in 2015.” The U.S. Air Force currently flies the high-altitude mission over and around the Korean peninsula using three Lockheed Martin U-2s based at Osan Airbase.
ITT Exelis for the first time exhibited its airborne sense-and-avoid (ABSAA) radar under development for the U.S. Navy’s MQ-4C Triton Broad Area Maritime Surveillance (Bams) unmanned aircraft system. The radar was displayed this week at the Unmanned Systems North America conference in Las Vegas. It is also being promoted for other UASs as a solution to flying in unrestricted airspace, branded as the SkySense 2020H radar system.
In the current fiscal environment in which big-ticket missile programs have been shelved, restructured or cancelled altogether, Raytheon is looking at innovative ways to add capabilities to existing systems. “You’ve got to see what you can do with what you’ve got,” explained Harry Schulte, Raytheon’s v-p Air Warfare Systems. “The money’s not going to be there for the big programs, but the enemy doesn’t care about that, and we still need to address the shortfalls.”
