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.
