India's Defence preparedness

DRDO is the main developer of India's defence arsenals.

Nirbhay
- Sub-sonic (less than the speed of sound) terrain-hugging cruise missile
- India's equivalent of Tomahawk
- Range : 1000 kms
- Launched from : any surface

A top DRDO official said the advantage with the “fast-reaction” Nirbhay was that it would be difficult for enemy radars to detect it.

The missile was highly manoeuvrable and could change the trajectory mid-course because of “waypoint navigation.”

Astra
- Beyond Visual Range Air-to-Air Missile (BVRAAM)
- Currently under development
- The 3.8 m long Astra is the smallest of the missiles developed by DRDO.

Nag
- Fire and forget anti tank missile with a range of 4 kms.
- NAMICA : The vehicle to launch Nag
- HELINA  : Version of Nag to be launched from helicopter

Agni and Prithvi variants are surface-to-surface missiles.
Dhanush is a naval variant of Prithvi.

Prithvi
- India's
Prithvi II : Personnel of Strategic Forces Command successfully test fired this surface-to-surface nuclear warhead capable, 350 kms range missile from a road mobile launcher.
It is a single stage liquid propellant missile.
Agni
- India's long range missile system
Agni III : Personnel of Strategic Forces Command will conduct a test- firing of this missile on Sep 21.

• 3000 kms range, surface-to-surface nuclear capable missile
• 2 stage solid propelled missile that can carry warhead of 1.5 tonnes.

- Agni IV : final developmental test flight on Sep 20. If successful, commercial induction into the services early next year.

• Two stage solid propellant
• Can carry payload of 1000 kgs till 4000 kms.
• Its re-entry vehicle is equipped with heat shield to enable the payload withstand searing temperatures of more than 3,000 degrees Celsius. 
The missile’s advanced ring-laser gyro-based INS ensures a high degree of accuracy.

- Agni V :

• 5000 kms. range.
