The Trophy active protection system creates a hemispheric protected zone around the vehicle where incoming threats are intercepted and defeated. It has three elements providing Threat Detection and Tracking, Launching and Intercept functions. The Threat Detection and Warning subsystem consists of several sensors, including flat-panel radars, placed at strategic locations around the protected vehicle, to provide full hemispherical coverage. Once an incoming threat is detected identified and verified, the Countermeasure Assembly is opened, the countermeasure device is positioned in the direction where it can effectively intercept the threat. Then, it is launched automatically into a ballistic trajectory to intercept the incoming threat at a relatively long distance.
Specific details about the composition and mechanism of this explosive interceptor device are vague. From the briefing provided by US sources, Defense Update understands that Trophy is design to form a "beam" of fragments, which will intercept any incoming HEAT threat, including RPG rockets at a range of 10 30 meters from the protected platform. The Trophy development roadmap considers an enhanced countermeasure unit to be available in the future, and protect against kinetic energy (KE) threats. Trophy was designed to effectively operate in a dense urban environment, where armored vehicles operate closely with integrated infantry forces. Therefore, direction, formation and energy of the fragments are designed to ensure effective target kill with low collateral damage, and low risk to nearby troops. While not in use, the system is maintained in the stowed position, protected by an armor shield. The system has an automatic reload mechanism to handle multiple attacks. The system can simultaneously engage several threats, arriving from different directions, is effective on stationary or moving platforms, and is effective against short and long range threats (such as RPGs and ATGM). Trophy was designed to be effective in open or closed terrain, including urban area and can be operated under all weather conditions. On March 30, 2006 General Dynamics announced the successful completion of a firing test, conducted at the request of the Office of the Secretary of Defense's Office of Force Transformation (OFT), to validate the Israeli Army's tests that demonstrated Trophy's ability to detect, track and destroy incoming rocket propelled grenades (RPG) at safe distances from the host vehicle. Trophy underwent this U.S. validation testing in support of OFT's Project Sheriff, or the Full-Spectrum Effects Platform (FSEP). FSEP program officials seek to meet urgent operational requirements for a range of lethal and non-lethal technologies on a rapidly deployable platform. Trophy was selected in 2005 to be FSEP's active protection solution. During the test, Trophy detected, tracked and defeated an inert incoming RPG while the Stryker combat vehicle was on the move. Similar tests were successfully conducted in Israel in late February. September 2006: The US Army opted to pursue a different system. Earlier in 2006, Raytheon received a development contract to demonstrate and develop the Quick Kill APS, to be integrated into the future FCS systems. The Army faced mounting criticism about not considering the Trophy system for the protection of its armored vehicles deployed in Iraq. Maj. Gen. Jeffrey A, Sorenson, the Armys deputy for acquisition and systems management explained the decision (AFPS) saying the Israeli system is not a produceable item. The Israelis have been working on the Trophy system for 10 or 11 years, Sorenson said. If this thing was ready to go, my question would be, why wasnt it on the particular tanks that went into Lebanon? he said. No Israeli Merkava tanks carried the Trophy system, he said. Other problems include the fact that the system right now has no reloading capability. Once it fires, that side of the vehicle is vulnerable. Which brings up another shortcoming: the Trophy can only be mounted to protect one axis. This means officials would have to mount multiple missile systems on every vehicle. The Quick Kill missile has 360-degree capability and a reload capability.
Another worry is collateral damage, he said. In a tight urban area, the Trophy system may take out the RPG, but we may kill 20 people in the process, Sorenson said. That is a concern we have that we havent fully evaluated. However, an NBC report aired May 7, 2007 claims that in contrast to Sorenson's observations, in a recent study made by the Institute for Defense Analyses (IDA) requested by the Office of the Secretary of Defense, following a law passed by the US Congress, Trophy was found to be in an advanced state of development (with a TRL of 7-8). while Raytheons Quick Kill was judged a 3 for threshold capabilities (RPGs, ATGMs). April 2007: The development of the Trophy Active Protection System has been completed, including integration of the system into current AFVs as well as the introduction of reloading systems, positioning the Isaeli active protection system as the first available system in the West. Initial systems are expected to go into new production and currently deployed Merkava tanks as well as the new Merkava based armored Infantry Fighting Vehicles (Namer). While the system has been approved for production, which still awaits funding allocation. After the recent conflict in Lebanon (July-August 2006), Active Protection Systems were identified as a critical complement for the protection of main battle tanks such as the Merkava Mk4. Trophy Light
a new version of RAFAEL's active protection system, unveiled at RAFAEL's display at DSEi 07 is based on the Trophy system, currently in production for Israel's Merkava tanks. Trophy Light is designed for integration with light armored vehicles, such as RAFAEL's Golan. The system will offer high probability of kill against advanced threats, including the most sophisticated shoulder-fired anti-tank rocket propelled grenades (RPG). The system utilizes the same operating principles of the Trophy, at scaled down proportions, facilitating installation on smaller, light armored vehicles, and operation at shorter ranges, therefore adapting to the typical operating environment of light armored vehicles. According to sources at RAFAEL, the development is a low-risk endeavor, as Trophy Lite will require only design and engineering work on the launcher/ loader and munitions. It is expected to weigh about half the weight of the standard Trophy, originally designed for main battle tanks. The system will use the same Elta radar used with the Trophy, and will employ electronic enhancements contributing to significant improvement in combat effectiveness. Trophy Lite is also expected to cost less, positioning it at a competitive advantage in the growing APS market.
