What are the best weapons India have?

1.Brahmos:

It is the world's fastest cruise missile in operation. The missile travels at speeds of Mach 2.8 to 3.0.

It can be launched from any Air,Surface, Ship and Underwater platforms.

2.Agni (Missile system).

The Agni missile is a family of medium to intercontinental range ballistic missiles developed by India, named after one of the five elements of nature. Agni Missiles are long range, nuclear weapons capable surface to surface ballistic missile. The first missile of the series, Agni-I was developed under the Integrated Guided Missile Development Program and tested in 1991. After its success, Agni missile program was separated from the IGMDP upon realizing its strategic importance. It was designated as a special program in India's defence budget and provided adequate funds for subsequent development. As of 2014, the Agni missile family comprises three deployed variants while two more variants are under testing

Agni missile system classification

Name      Type          Range                    Status
Agni-I     MRBM 700 – 1,250 km    (Operational)
Agni-II    IRBM  2,000 – 3,000 km (Operational)
Agni-III  IRBM  3,500 – 5,000 km  (Operational)
Agni-IV   IRBM 3,000 – 4,000  km  (Operational)
Agni-V    ICBM  5,000 – 8,000 km    (Testing)
Agni-VI  ICBM  8,000 – 10,000 km   (Under development)

Speed Mach 24.

3.Akash (missile)

Akash is a medium-range mobile surface-to-air missile defense system developed by the Defence Research and Development Organisation (DRDO),Bharat Dynamics Limited (BDL) for Missile Systems, Ordnance Factories Board and Bharat Electronics (BEL) for other Systems inIndia. The missile system can target aircraft up to 30 km away, at altitudes up to 18,000 m. It has the capability to "neutralise aerial targets like fighter jets, cruise missiles and air-to-surface missiles" as well as ballistic missiles. It is in operational service with the Indian Army and the Indian Air Force.

An Akash battery comprises four 3D passive electronically scanned array radars and four launchers with three missiles each, all of which are interlinked. Each battery can track up to 64 targets and attack up to 12 of them. The missile has a 60 kg (130 lb) high-explosive, pre-fragmented warhead with a proximity fuse. The Akash system is fully mobile and capable of protecting a moving convoy of vehicles. The launch platform has been integrated with both wheeled and tracked vehicles. While the Akash system has primarily been designed as an air defence SAM, it also has been tested in a missile defense role. The system provides air defence missile coverage for an area of 2,000 km². The Indian military's combined orders of the Akash, including radar systems (WLR and Surveillance), have a total worth of RS.23,300 crore (US$4 billion).

4. Astra

Astra is an active radar homing beyond-visual-range air-to-air missile (BVRAAM) developed by the Defence Research and Development Organisation (DRDO), India. Astra is designed to be capable of engaging targets at varying range and altitudes allowing for engagement of both short-range targets (up to 20 km) and long-range targets (up to 80 km) using alternative propulsion modes. Except for a failure in one test, the missile has successfully completed all its tests. The missile was last tested on 18 March 2015 from a Su-30MKI fighter against a simulated live target. Astra uses a smokeless propulsion system.

Operational range: 80 km in head on chase.
Max Speed:4.5+ Mach.
