Ground Launched Small Diameter Bomb (GLSDB) – An Artillery Game Changer

Saab, together with Boeing, has proven that the Small Diameter Bomb Increment, originally developed for use by aircraft, can be adapted for launch from a ground artillery system.

The companies recently tested the Ground Launched Small Diameter Bomb (GLSDB), integrating the SDB I and M26 rocket motor technologies for the Multiple Launch Rocket System. The testing showed that the bomb can withstand a rocket artillery launch without its performance being compromised.Developed in partnership with Boeing, the GLSDB is a flexible, precise and reliable weapon that exemplifies the value of Saab´s thinking edge.

The GLSDB is a system which gives a long range precision incendiary solution that widens the capabilities of armed forces. It is highly effective and accurate over long range. It is more or less designed to meet to evolving needs of today´s and also tomorrow´s armed forces.GLSDB combines two highly successful, combat-proven systems into an effective ground forces offensive capability. GLSDB allows the artillery system to reach targets from significantly longer distances, and engage hard-to-reach targets, while maintaining the Small Diameter Bomb’s flight maneuverability and accuracy.

Under a teaming agreement signed last year, Boeing and Saab will offer GLSDB to current and future rocket artillery users.“Saab is proud to expand our already successful cooperation with Boeing into yet another technology area – precision weapons systems. Together, we now can offer a new and game-changing capability for the world market”, says Görgen Johansson, head of business area Dynamics within Saab.

Highly effective and accurate over long ranges, the GLSDB is designed to meet the evolving needs of today´s and tomorrow´s armed forces. GLSDB has the ability to fly complex trajectories and manoeuvres to strike targets that cannot be reached by conventional direct fire weapons. GLSDB gives land forces a mobile, organic capability to hit targets that were previously out of their reach by taking advantage of the Small Diameter Bomb’s inherent maneuverability and accuracy. Capable of conducting reverse slope engagements and defeating a range of targets, from hardened facilities to soft-skinned assets, the GLSDB adds another dimension to armed forces´ capabilities.

With 360 degrees target engagement ability, the GLSDB provides commanders and planners with a flexible weapon which complements existing ballistic trajectory weapons. The weapon builds upon the successful Small Diameter Bomb Increment (SDB I) and the Multiple Launch Rocket System rockets.The SDB is a 250-pound class weapon with an Advance Anti-Jam Global Positioning System-aided Intertial Navigation System, combined with a multipurpose penetrating blast-and-fragmentation warhead and a programmable electronic fuze.
The GLSDB provides:
• Increased range
• Accuracy to within one metre
• All angle, all aspect attack - even targets behind the launch point
• Multiple rockets to act against multiple targets, with near simultaneous impact
• All weather, 24/7 capability
• Terrain avoidance, such as mountains
• Cave breaching capability
• Launches from hidden or protected positions to avoid detection
• Programmable fuze for impact and delay fuzing for deep penetraion or proximity height-of-burst
• SDB Focused Lethality Munition (FLM) variant is also an option for low collateral damage
• Laser SDB variant provides moving target capability
• Range up to 150 kilometer
• Load out of up to six rockets per pod
• Designed to minimise collateral damage
• Complete SDB flight maneuverability
