DRDO-Developed Low-Drag Glide-Bomb Data
The 1,000kg low-drag, high-explosive aerial bomb has been developed and is being produced by OFB Khamaria. The bomb, with a designation of Mk12, has a length of 4,000mm and weighs about 930kg.
The DRDO-developed 100km-range, 1,000kg low-drag glide-bomb has been jointly developed with Russia’s Joint Stock Company ‘Scientific Production Association Bazalt’ (JSC SPA Bazalt) and its local industrial partner Basant Aerospace Pvt Ltd.
While the DRDO developed the on-board MINGS-based inertial and terminal navigation system, the glide-kits and rear-end structural sections have come from JSC SPA Bazalt. The PGM will be used primarily against static targets like bridges, railway junctions, and logistic hubs for POL and ammunition storage.
The Russia-origin glide-kit will also be used by the IAF’s existing Mk11N high-explosive, 1,000lb low-drag aerial bombs.
