The Israel Defense Forces announced
on August 6 that it had successfully completed a series of tests on
a new defense system for the Merkava
Mark IV Main Battle Tank (MBT).
The system, known as
“Trophy" was developed by Army Headquarters in
cooperation with the Rafael
Armaments Development Authority and the Defense Ministry.
The system includes an F/G Band fire-control
radar with four flat-panel antennas mounted on the vehicle, with a
360-degree field of view. When a weapon is fired at the vehicle, the
internal computer uses the signal from the incoming weapon and
calculates an approach vector. Once the incoming weapon is fully
classified, the computers calculate the optimal time and angle to
fire the neutralizers. The response comes from two rotating launchers
installed on the sides of the vehicle. The launchers fire the
neutralizing agents, which are usually small metal pellets like
shotgun shot. The system is designed to have a very small kill zone,
so as not to endanger troops adjacent to the protected vehicle.
The system is designed to work against all types of anti-tank
missiles and rockets, including handheld weapons such as rocket
propelled grenades. The system can simultaneously engage several
threats arriving from different directions, is effective on
stationary or moving platforms, and is effective against both short
and long-range threats. Newer versions of the system include a reload
feature for multiple firings. The Trophy development roadmap includes
an enhanced countermeasure unit to be available in the future for
protection against kinetic energy penetrators.
There is also a
version called “Trophy Light” which is meant to be fitted on
light vehicles, such as the M113, Stryker, "Golan", and
"Wolf" APCs.
The first battalion of Trophy equipped
Merkava IVs are expected to be fielded in 2010. The system will be
fully integrated into existing Merkava III and Merkava IV MBTs as
well as the Namer APC.
Trophy is not the worlds first Active
Protection System (APS), that honor falls to the Russian designed
Drozd and Arena APS's. However these systems have not seen widespread
deployment, with only 255 T-55Ms equipped with Drozd and an unknown
amount of other tanks equipped with Arena.
The U.S.
Army tested Trophy in 2006 but decided to hold off purchase in favor
of their native APS under development by Raytheon, “Quick Kill”.
However, this system is not expected to fielded for some time.
