Isn’t the Pentagon looking to buy some of these?
Every system has its limitations.

“MSNBC has reported that there is resistance to incorporating Trophy in the US Army. The U.S. Department of Defense has contracted with Raytheon to develop an equivalent system, Quick Kill, which will not be ready before 2011 at the earliest (but now declines to say whether it still is on course to meet that deadline), whereas Trophy could be deployed much sooner. Quick Kill is more similar to Israel’s other developing active protection system, Iron Fist. According to MSNBC’s sources, the reason for not adopting Trophy for now is that it would remove the need for the Raytheon program.
“The Institute for Defense Analyses analyzed 15 active protection systems, including Trophy and Quick Kill, and found Trophy to be the top system. In March 2006, Pentagon testers at the Naval Surface Warfare Center in Dahlgren tested Trophy. An official involved with the tests told NBC that Trophy “worked in every case. The only anomaly was that in one test, the Trophy round hit the RPG’s tail instead of its head. But according to our test criteria, the system was 30 for 30.”
“The Government Accountability Office has since reviewed the Army’s actions and issued a report that concluded that the Army and Boeing, the FCS lead systems integrator, followed the regulations to avoid conflicts of interest; that although Raytheon’s technology is not mature, the Army estimated that a prototype for current vehicles could be delivered by 2009; that Army officials found Trophy tests to be unrealistic, and worried that integrating Trophy would delay fielding other capabilities.
“According to the DOD Buzz the United States will be testing the trophy system on a Stryker vehicle in 2010.
“On 12 November 2009, Ph.D. Vladimir Korenkov, who led Russian state unitary enterprise “Basalt” from 2000 to 2009, stated that “The Israeli system of active protection of tanks, “Trophy”, as any other similar systems, can be evaded”. One of the activities of this enterprise was to develop rocket-propelled grenades, designed to destroy modern armament. The rocket-propelled grenade RPG-30, according to Vladimir Korenkov, is designed to overcome these tank defense systems. “All the existing active protection systems in the world share the same idea. This is a radar homing at some distance, close or far, to destroy the target with a warhead that creates fragment stream and explosive field. These systems have common flaws. First of all, the duty cycle, i.e. the time interval of the system response to the threat. RPG-30 easily defeats such a protection system. There is a smaller diameter precursor round in addition to the main round. This precursor acts as a false target spoofing the APS into engaging it and allowing the main round (following the precursor after a slight delay) a clear path to the target, while the APS is stuck in the 0.2 - 0.4 second delay needed to start its next engagement. This time interval is sufficient for defeating the Israeli system”, said Vladimir Korenkov.”
