Trophy.


This is coolbert:

Here is a system effective [95 %??] against the RPG [rocket propelled grenade].

Developed by Rafael, an Israeli weapons system design company.

Called Trophy. Designed to defeat the HEAT round fired by the RPG.

That HEAT round so deadly when used against armored vehicles. The weapon that allows the common infantryman to become a tank killer.

This Trophy system is able to detect the incoming warhead and take counter-measures that explode the warhead before it detonates on the armor of the tank. Defeats the normal HEAT round, the tandem-warhead HEAT round, all HEAT rounds from the RPG.

NOT exactly sure how it works. Sends a spew of ball-bearings at the round to impact with and detonate the warhead in mid-flight? The U.S. Army has also designed such a system. But the Israeli unit is ready to go now? More effective too?

"Resistance from the US Army"

"MSNBC has reported that there is resistance against incorporating TROPHY in the US Army. The US has contracted Raytheon to develop an equivalent system, which will not be ready before 2011 at the earliest, whereas TROPHY could be deployed much sooner. According to MSNBC's sources, the reason for not adopting TROPHY for now is that it would remove the need for the Raytheon program, causing it to be canceled."

"Trophy is design [ed] 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 Russians FOR SOME TIME NOW have had a system at least SOMEWHAT analogous to Trophy. This is the Shtora system.

Shtora detects when a Russian tank [T-90 version] is being "illuminated" [that is the word the military likes to use!] by a laser. A laser that is guiding an anti-tank guided missile [ATGM] on to the target [the tank]. Shtora detects the laser and automatically [?] takes active measures to counter the guidance system of the enemy laser guided ATGM.

Measures including:

* An aerosol spray and smoke dispensed and enveloping the tank with a "cloud" to defeat the ATGM. The smoke and aerosol mist dissipating that laser beam and making it impossible for the ATGM to be guided to the target. A COUNTERMEASURE.

* Misdirects the ATGM by using an infra-red source. JAMMING.

"an IR source that mimics the flare on the back of missiles"

"'hijacks' the missile's command link by feeding the tracker with modulated signals that cause the missile to deviate from its course, and away from its intended target."

This Trophy system is more active than Shtora in that it "destroys" in mid-flight the RPG round! Can do so to an ATGM too!? Shtora deceives and "blinds" at the same time. Trophy wants to eliminate!
