Trophy active protection system on a Merkava 4
any time. Every single round is stored in a protective
container, to safeguard the crew in case of an
ammunition explosion. The loader semi-automatically
selects the ammunition type.
As the radar and other sensors that are part of
the Rafael Trophy active protection system are used
not only to detect an incoming missile but to supply
situational awareness to the tank commander, the
Merkava 4, according to the program manager, is
capable of destroying the launcher.
"As all the anti tank weapons we have to deal with
require a continuous control by the operator, such
rapid fire response by the tank is also a defensive
action. If the launcher is hit, the launched missile will
lose its control" Matzliach said.
The Mekava Mk4 is armed with two types of
rounds developed by Israel Military Industries (IMI)
that can hit the enemy when they hide in a building
or behind a hill.
The new fire control system of the tank, developed
by El Op, includes many advanced features. A very
impressive one is the capability to acquire and lock
onto moving targets, even airborne helicopters,
while the tank itself is on the move - and not only
on a flat surface.
The commander's station is fitted with
a stabilized panoramic day and night sight. The
integrated operating system includes advanced data
communications and battle management.
The IDF will not provide any detail on the armor of
the tank and refers to it as a "special armor".
This special material also protects the turret as
well as the hull. The tank is protected against a range
of threats, including air-launched precision-guided
missiles and advanced and top-attack anti-tank
weapons. Automatic fire detection and suppression
has been installed. The underside of the hull has been
fitted with additional armor to increase protection
against buried explosive devices. After the second
Lebanon war this feature was improved but no details
The crew compartment is fully air-conditioned
and has overpressure protection systems against
contamination by chemical warfare materials.
A special Battle Management System (BMS) that
provides fast communication networking between
the commander and other tanks and units in the
combat zone is one of the very advanced systems
installed in the latest version of the Merkava .
"This system is the basis for situational awareness
that is so crucial in the heat of the combat. It also
helps the Merkava Mk4 to maintain its capacity to
destroy other tanks."
The situational awareness of each tank is based
among other inputs on four cameras installed outside
the vehicle. These cameras provide a full peripheral
view displayed on high-resolution monitors installed at
the driver's position and in the fighting compartment.
Additionally, training features are embedded
in each MBT, which allows each crew to train at
almost any time. The built-in training capability
allows the crew to use a set of virtual terrain
features, and friendly and enemy elements to build
a "combat scenario".
These generated scenarios are presented
to the tank crew and unit members through their
observation systems, sights and sensors, to support
a comprehensive training scene in the field.
This main battle tank is powered by an MTU USA
883 V-12 diesel engine. It develops 1500 horsepower
and delivers 25% more power comparing than the
previous 1200 hp engine on the Merkava Mk3.
The turret is controlled by an electric gun control
system, which comprises two brushless motors.
This system is a highly improved version based
on lessons derived from using the earlier ones in
training and in combat.
The tank is fitted with a laser warning system, with
threat warning display installed at the commander's
station. When a threat is detected it is transferred
directly to a pedestal-operated, multi-ammunition
launching system designed to fire decoys.
The Merkava 4 has a crew of four, namely: the
commander, gunner, loader and driver.
The unique design of the series with front-mounted
engines allows free space for the troops or cargo at
the rear of the hull. When ammunition is unloaded
the tank can carry up to 8 dismounts or 3 stretchers.
Troops enter and leave the vehicle through the rear
. hatch. This unique capability allows for the delivery of
troops directly to the battlefield, or to evacuate them.
As mentioned earlier, after the second Lebanon
war, all the Merkava 4s have been fitted with
the Rafael Trophy Active Protection System. This
unique product provides 360° coverage against
anti-tank rockets, anti-tank missiles and HEAT
(high-explosive anti-tank) rounds. Once Trophy has
detected a threat, it is tracked and classified and
the optimal intercept point is computed prior to
launching a countermeasure.
Brigadier General Matzliach rejects any claim that
the projectile launched by the Trophy to destroy the
incoming threat endangers infantry soldiers that are
in the vicinity of the tank. " The tank commander if
he has his head out, is protected by a special shield.
It is proven that the warhead of an incoming anti
tank missile poses more danger to infantry than the
projectile of the protective system."
Israeli experts said that the Merkava 4 is better than
all other MBT's that are being used now in combat.
" The Leopard tanks used by Turkey in Syria were hit
one after the other by anti tank weapons operated by
ISIS" one of them said.
Sources in Israeli industry say that 70 % of the
Merkava Mk4 is made in Israel by hundreds of large
