DRDO working on a 300mm Long Range Guided Rocket for the Indian Army that will have a range of 300kms !!
The DRDO’s Armament Research and Development Establishment (ARDE) has started a new project known as 300 millimeters LRGR (Long Range Guided Rocket) under which it will develop a 300 millimeters long range guided rocket for the Indian Army.
It will carry a 150 kilograms warhead and is expected to have a range of around 300 kilometers and will also counter the Chinese A-300 type of rockets operated by the Armies of both China and Pakistan.
The A300 is one of the latest Chinese artillery rocket systems. Â The A300 is designed to attack important area targets well behind the enemy lines. The launcher vehicle carries 2 pods with four 300 mm rockets each. It has been reported that the A300 is a modular system, that can also use pods of A200 and possibly other calibers.

The A300 has a maximum range to 290 km, opposed to 200 km of the earlier A200. The A300 has a larger engine than its predecessor. Currently this Chinese artillery rocket system has the longest range in the world.
The A300 rocket carries a 150 kg warhead. It is believed that several types of warheads are available. IgMp
