The Israel Defense Forces publishes footage of the exercises using upgraded Accular-160 high-precision artillery rockets.
ACCULAR, a unique Israel Military Industries development, is an accurate artillery rocket system, based on the LAR family. With its unique trajectory correction system, accuracy of the rockets is said to be equal to that of conventional tube artillery.
According to Israel Military Industries, it was only natural that this artillery rocket system will be significantly upgraded to better meet the requirements of the modern battlefield.
As with other members of Israel Military Industries family of artillery rockets, the system can be used on various ground platforms including tanks, standard trucks, trailers and others.
In addition, for rapid deployment forces and their requirement for air transportability, special towed models are also available.
The modular design of the system allows varying the quantities of rockets (8, 10 or 13) in sealed launch pod containers on the launcher to meet the load capacity.
The ACCULAR concept can be adapted to different types and sizes of Israel Military Industries rockets and is valid through all artillery ranges.
The ACCULAR is claimed to represent only a moderate increase in cost. The major investment (technological and economic) is made on the existing command post while the cost increase in the rocket is relatively marginal.
By providing artillery rockets with increased accuracy to a level of that obtained by conventional tubed artillery systems, ACCULAR enables the optimal deployment of smart munitions (such as top attack type or scatterable anti-tank mines) which require deployment in close vicinity to the target.
The Israel Military Industries ACCULAR concept may be adapted to different models and types of rockets and claimed to be a major breakthrough in this field as the upgrading of a free-flight rocket has now become a reality.
This system has now been applied to the MLRS used by the Israel Defence Force under a contract awarded in mid-1998 to Israel Military Industries. Lockheed Martin Missiles and Fire Control, prime contractor for the 227 mm MLRS system, is also involved in this programme.
Late in 2003, Israel Military Industries announced that it had successfully completed flight tests for its trajectory correction system for the Lockheed Martin Missiles and Fire Control 227 mm MLRS rocket.
The design verification, conducted late in September 2003, for a range of 35 km, marked the end of a 10-year development contract to enhance the accuracy of the 227 mm MLRS rockets used by the Israel Defence Force. The system is now in production for the 227 mm MLRS used by the IDF.
According to Israel Military Industries, the trajectory correction system will reduce by 95 per cent the number of rockets required to neutralise a given target when compared to standard production unguided rockets.
The 160 mm ACCULAR is fitted with a Trajectory Correction System (TCS) which includes a steering unit mounted towards the nose that includes an electronic unit, gas generator and valve.
After launch, the ground control unit establishes a datalink with the rocket and calculates the current trajectory and corrections necessary to reach the target.
The actual course correction phase is carried out as the rocket is accumulating environmental data that affects its flight course. Through this process, course correction is performed in a closed loop as the ground control unit commands the rocket steering to correct its trajectory.
The type of warhead depends on the user’s operational requirement, for example a cargo warhead containing 104 High-Explosive Anti-Tank (HEAT) bomblets fitted with a self-destruct fuze mechanism.
