48.Eocm-Class Laser System
DRDO has developed a portable dual-role EOCM laser system suitable for both anti-sensor as well as dazzling applications with an operational range of 2.5 km. It is basically a frequency-doubled Q-switched Nd:YAG laser capable of producing dual wavelength output at 1064 nm (IR) and 532 nm (green). While the IR output is used for anti-sensor applications, output in green iDEALly suits dazzling operation. The system comprises a laser head with associated sighting system, an electronics unit, a power pack, and a tripod stand. It has a day/night sighting telescope target acquisition and weighs 30 kg (can be carried by two persons).
Salient Features
Gross pointing : Pan/tilt
Laser firing mode : Manual/auto
Pulse repetition frequency : Single pulse/1 pps
The system has been tested for its efficacy against various optoelectronic sensors including silicon PIN photodiodes and APD (representative of laser range finders and target designators), CCD cameras representative of target acquisition systems) and night vision devices.
49.Palmtop Green Microchip Laser Module
These devices can generate beams with extremely high beam quality, single longitudinal mode and ultra short pulse durations. The microchip concept has also been extended to include both high power, Q-switched and electrooptically tunable devices. Such features make them very attractive for many scientific, industrial and defence applications.
DRDO has developed a palmtop green laser module generating 50 mW power @ 532 nm in CW mode. It is based on a diode pumped Nd:YVO4 microchip laser with KTP crystal for intracavity second harmonic generation. The module contains a 500 mW laser diode (808 nm) with integrated driver. A short focal length lens has been employed for focusing the beam inside the monolithic microchip laser.
50.Hull Mounted Sonar Advanced (HUMSA)
HUMSA is the enhanced version of the state-of-the-art Hull Mounted Panoramic Sonar designed for the Indian Navy in the nineties. This family of medium range active-cum-passive dual band sonars, optimised for both shallow and deep-water operations has proved its efficacy even in the highly variable tropical waters for more than a decade. HUMSA's advanced signal processing techniques are responsible for its superior performance. The sonar uses multiple transmission modes for short and long-range surveillance. It also provides selective sector illumination to minimize interference in case of multi ship operation. The sonar can be factory-tuned to operate at any frequency. It can be configured for dual or single operator mode and hence can be fitted in ships of various tonnages. A built-in signal simulator enables the performance evaluation before sea going and also provides operator training and confidence building. The sonar can be supplied with wide range of cylindrical transducers to meet the specific requirements
HUMSA NG is a technology upgrade of HUMSA with lower frequency transducers and state-of-the art electronics containing POWER PC processors and SHARC signal processing boards.

52.BUND BLASTING DEVICE
Reduction of a high bank is a critical activity in an opposed crossing across a water obstacle/river/canal/ditch-cum-bund, within the tactical time frame available for launching a suitable bridge to ensure the mobility of mechanised army. Conventionally, the task is accomplished with the help of earth augers or by placing plastic explosive inside the hole and creating breach by initiating it. The method is quite cumbersome, time consuming and exposes the army personnel to the enemy for longer duration. DRDO has designed and developed a man-portable Bund Blasting Device to overcome these problems. The newly developed device is based on the principle of hollow charge and a rocket-assisted high explosive (HE) follow-through projectile.
The system consists of a hollow charge initiation device and the main HE- filled projectile attached to a rocket motor. The hollow charge on initiation creates a deep pilot hole. HE projectile on entering this hole detonates, creating a big crater fulfilling the requirement. To remove/lower the height of bunds, an array of such devices is fired to get the desired result within the shortest possible time.
Follow-through Projectile: A cast aluminium shell has been developed to hold the main bursting charge. A suitable coupling has been made to accommodate the 68 mm arrow rocket motor. The design caters for accommodating the booster and the detonator. It has been developed with a proper MS liner and RDX/TNT explosives in an appropriate ratio to achieve the hole of required diameter and depth.
53.MULTIMODE GRENADE
DRDO has developed a general purpose antipersonnel grenade, named Shivalik, for use in offensive and defensive role in the hand mode and for launching from the rifle by using normal ball ammunition. The bullet trap technology used in the grenade eliminates the need of the special ballistite or gas cartridge for launching grenade from the rifle. The state-of-the-art multimode grenade Shivalik thus enhances the fire power of the infantry soldier manifold.Technological Features
Modular Design: Shivalik has three basic modulesfuze, grenade body and launcher tube. The different modules can be assembled or dissembled with ease. It is possible to prime and unprime the grenade any number of times without affecting its efficiency. The fuze assembly forms the basic module. With the explosive filled non-splintering body, it forms an offensive grenade. Addition of fragmenting sleeve transforms it into defensive grenade and the attachment of a launch tube converts it into a rifle grenade.
Multi-Mode Concept: Shivalik is multi-functional depending on the situation. In offensive role, it is used in the final stages of assault from a distance of about 50 m from the line of enemy defence. Being non-splintering type, offensive grenade on detonation stuns the enemy through concussion effect within a radius of about 5 m from the point of burst. In the defensive mode, it is used against the enemy troops in open when our own troops are in defence. The controlled and uniform spread of the fragments from the fragmenting sleeve can incapacitate a human being within a specified radius from the point of burst, but causes no harm to our own troops beyond a certain predetermined distance.
The technology of the prefragmented pellets, embedded in a plastic matrix has been fully established. The main bursting charge is precast pellet (RDX/TNT), the technology for which has been developed indigenously. The bullet trap technology has been incorporated in the launching tube, which enables use of normal ball ammunition for its launch from 5.56 mm INSAS rifle.
Fuze: The fuze has been designed to function on impact with a guarantee of self-destruction due to incorporation of a predetermined delay. The fuze functions at all angles of impact. An additional safety mechanism has been provided by a shutter mechanism blocking the explosive train. A safety lever mechanism has been incorporated to hold the safety pin secured. In rifle grenade lever is secured by a metallic ring which flies back due to set back forces on firing arming the fuze after a safe distance
Sight: A bubble sight has been provided for mounting on the rifle to aid the firer to achieve the desired ranges at different firing angles. The maximum range achieved by the rifle grenade is 200 m in comparison to 120 m presently achieved from M 36 grenade.
The grenade body has been made very light and compact by using special polymers. The shape is more ergonomical. The grenade, besides being paradroppable, can be used in the temperature range of -20 oC to +55 oC and is not affected by rain or humidity conditions. The grenade is maintenance free. The Shivalik grenade is in the final stages of user trials. With its introduction into the Services, it will substantially contribute to the infantrys capabilities in the battlefield and the country will move one step forward towards its mission of self-reliance.
54.HIGH SPEED LOW DRAG AIRCRAFT BOMBS
Conventional 1000 lb class of aircraft bombs offer more drag, thereby adversely affecting the operational efficiency of modern high speed aircraft. Keeping this in view, DRDO has designed and developed high speed low drag (HSLD) bombs in 450 kg and 250 kg class suitable for carriage and release by modern aircrafts. These bombs are effective against ground targets like railway yards/bridges, major installations, bunkers, runways and hARDEned targets.
The bomb consists of two major subsystems, namely, bomb body filled with HE and tail unit. Two types of tail units, RetARDEr Tail Unit (RTU) for high speed low level bombing and Ballistic Tail Unit (BTU) for high speed high altitude bombing have been developed for the bomb to be used in different tactical roles.
The HE filling of the bomb is Dentex (RDX/TNT/Aluminium) for achieving maximum blast and fragmentation effect for inflicting maximum damage to the target. The bomb can be carried on various in-service aircraft like, Jaguar, MiG and futuristic combat aircraft of the the IAF.
The 450 kg HSLD Bomb is already in service and under production at the Ordnance Factories. The 250 kg HSLD Bomb with RTU has been introduced in the Services. BTU has successfully completed flight trials and awaiting introduction into the Services.
