DSA NEWS IN BRIEF
21 Apr 08. BAE Systems showed its Lemur system on its Stand at DSA. Lemur is a complete fire control system and a remotely controlled weapon station with independent line of sight (elevation) in the same mount. Modern systems for ground and naval operations must be able to operate in different levels of conflict. From peacekeeping operations where the Lemur™ is used for surveillance, firing warning shots and law enforcement missions against pirates and smugglers. To full war conditions where the Lemur™ is a vital part of the carriers’ self-defence and engagement against ground, surface and aerial targets. Lemur™ is a family of gyro-stabilized fragment protected, electro-optical sights and remotely controlled (RC) weapon systems. The flexible modular design allows Lemur™ to be customized for a large variety of requirements. It can be used in a number of applications on different types of platforms:
Fire control system against ground and air targets
Sight and designator for missile control
Commander’s sight
Forward observer instrument
Remotely controlled weapon station and with optional launchers for countermeasures.
As an panoramic platform Lemur™ can be fitted with various types of sensors, such as CCD camera, thermal imager, laser rangefinder, laser designator and missile sight. The sensor configuration depends on the use and customer’s requirements. The armoured cover protects against fragments and small-arms fire.
The Lemur™ SW is a combined EO director with a complete fire control system and
a remotely controlled weapon station with independent line of sight (elevation)
in the same mount. The on-mount weapon can be used in a variety of tasks, such as engaging small surface and air threats in all levels of conflict. Lemur™ SW can be used as the main FCS or as an alternative redundant FCS for ground and naval carriers. It is designed to match Bofors 40 and57 mm or other guns. Lemur™ has full capability to handle the programmable 3P all-target ammunition. The programming is controlled via the MMI and with customer defined firing doctrines. The electro-optical platform houses tracking and ranging sensors, LRF, TVC and IRC. The sight with fire control computer comprises a complete FCS. The FCS provides interfaces to the carriers navigation system, navigation radar or/and surveillance radar. The FCS handles different types of designation and co-ordinate systems.
The system is in service with the Danish Army on all its vehicles including Piranha, Bison and Eagle. It has a Brimar touch-screen controlled by an Ultra controller.
21 Apr 08. BAE Systems also showed its FH77 BW L52 – Archer. Archer is a 155mm FH77 B05 L52A wheeled, self-propelled 155 mm L52 automatic howitzer has been developed, based on the successful towed FH77 B. The new FH 77 BW L52 howitzer will have state-of-the-art tactical and technical performance. The range is 40 km with today’s ammunition and 60 km with the M982 Excalibur. Holding 40 onboard rounds, of which 20 are in a fully automated magazine. The entire crew is protected by armour in combat. The crew consists of 3-4 men. The gun, mounted on a Volvo R-30E articulated construction vehicle chassis, can reach road-speeds of up to 70 km/h and can be air-transportable in an A400M. Most of the existing FH 77 B weapon system is retained.
Performance:
Salvo: 3 rounds in 15 seconds.
Intensive fire: 20 rounds (a full magazine) in 2.5 minutes.
Continuous fire: 75 rounds an hour
Multiple Round Simultaneous Impact, MRSI, up to 6 rounds
