  • India successfully test-fires 'Dhanush' missileIndia on 23rd February successfully test-fired the nuclear-capable surface-to-surface Dhanush ballistic missile with a strike range of 350 km from a naval ship off Odisha coast at around 1052 hrs. 

    This naval variant of the indigenously-developed Prithvi-II missile was test-fired from the ship positioned near Paradip in the Bay of Bengal. 

    'Dhanush' missile has a length of 8.53 meters and 0.9 metre wide is capable of carrying a payload of 500 kg and hitting both land and sea-based targets. 
  • India successfully test-fires Agni-II ballistic missileIndia’s surface-to-surface Agni-II ballistic missile, with a strike range of 2 thousand kilometres was on 20thFebruary test-fired successfully from the Abdul Kalam Island, off Orissa coast. As part of user trial, the Strategic Forces Command with logistics support from Defence Research Development Organisation (DRDO) carried out the test. 

    Defence sources said the test was aimed at re-establishing the operational effectiveness of the weapon system. The successful launch once again proved the reliability of the medium range surface to surface missile. 

    The two-stage missile equipped with advanced high accuracy navigation system, guided by a novel scheme of state of the art command and control system was propelled by the solid rocket propellant system. The surface-to-surface missile can carry a nuclear payload of 1 thousand kilograms. 

    The range of the 21-metre long missile weighing 17 tonnes can also be increased to 3 thousand kilometres by reducing the payload. Agni missile series being developed by DRDO as a deterrent against nuclear-armed neighbours are among India’s most sophisticated weapons. 

    The test came two weeks after India successfully test-fired its indigenously developed Prithvi-II missile as part of a user trial by the Army from a test range in Odisha. 
  • Environment Minister Harshvardhan launches PetaFlop super computerEnvironment Minister Harshvardhan on 30th January launched a 2.8 PetaFlops capacity high-performance computer system 'Mihir' in NOIDA. The system will be able to predict weather and climate accurately. With the launch of the system, India has joined the elite 30 member group of countries which have this advanced technology. 
  • Indian Navy launches third Scorpene class submarine INS KaranjThe Indian Navy on 31st February launched the third Scorpene-class submarine Karanj at Mazagon Dock Shipbuilders Limited in Mumbai.
