Who has successfully test-fired 500 kg class guided bomb at Pokhran in Rajasthan?

Defence Research and Development Organisation (DRDO) has successfully test-fired an indigenously-developed 500 kg class guided bomb from a Sukhoi combat jet at Pokhran in Rajasthan. The test firing of the guided bomb came two days after the Indian Air Force successfully test fired the aerial version of the supersonic BrahMos cruise missile from a Sukhoi jet at the Andaman and Nicobar Islands. The 2.5-tonne air-to-surface missile has a range of around 300 km, and it will significantly enhance the IAF's combat capability.
