An intercontinental ballistic missile, or ICBM, is a very long-range (greater than 5,500–km or 3,500 miles) ballistic missile typically designed for nuclear weapons delivery, i.e., delivering one or more nuclear warheads.

ICBMs are differentiated by maximum range from other ballistic missiles: intermediate-range ballistic missiles (IRBMs), short-range ballistic missiles, and the newly named theater ballistic missiles.

The following nations currently have operational ICBM systems: Russia, the United States, France [1], the United Kingdom, and People's Republic of China. India has IRBMs but is developing ICBMs . Pakistan has IRBMs but is also researching ICBMs

In 2002, the United States and Russia agreed in the SORT treaty to reduce their deployed stockpiles to not more than 2,200 warheads each.

India's DRDO has dedicated considerable resources to the Integrated Guided Missile Development Program. Currently this program has produced two classes of missile designs inducted into the Army and Air Force and have been deployed by specially formed missile corps. It is unclear if the Agni has been deployed, but Agni I and II are believed to have been inducted into the Army. The Agni III is scheduled for testing by year end 2005. Further, analysts believe India is developing an SLBM (Submarine-launched ballistic missile) 'Sagarika'. The Indian DRDO has successfully launched a version of the Prithvi from an underwater pontoon launcher as well as from the deck of an offshore patrol vessel indicating work on SLBM technology.

The Deccan Herald and Carnegie Endowment reported that India is developing an intercontinental ballistic missile (ICBM) called Surya. India claims the ICBM is not only "intended to deter Europe and the U.S.", but also the People's Republic of China. It is expected to have a flight range of 9,000-12,000 km.

The missile is meant as a first-strike, "derived directly from its civilian satellite launch system (the Polar Space Launch Vehicle)". It is projected to be a “three-stage ballistic missile with solid fuel rockets in the first and second stages, and a liquid propellant rocket in the third stage”. The expected launch weight of the missile could “reach 270-275 tonnes and an impact error of around 2 to 2.8 km”. The ICBM is "likely to be test-fired by 2008", and expected to be included into "the Indian armed forces’ deterrence arsenal by 2015".



The development for the intermediate-range ballistic missile, called Agni 1 (Fire), started around 1979 under the direction of the Indian Defence Research and Development Laboratory (DRDL) at Hyderabad. Agni 1 uses a first-stage motor similar to the first-stage solid rocket motor from the Indian Satellite Launch Vehicle-3 (SLV-3) based upon an earlier US Scout rocket design. SLV-3 has been used in various satellite launches since 1979. The second stage of Agni 1 uses a shortened Prithvi missile liquid-propellant motor system.
    There were conflicting reports in 1995 concerning the Agni programme. One report suggested that the programme had been halted due to technical difficulties. The second report suggested that the Indian government was planning a further five test launches. However, in December 1996, the Indian government announced that the Agni 1 trials programme would be terminated, but in July 1997, the development programme was restarted. It seems likely that the programme was restarted as a result of the development of new solid-propellant ballistic missiles in China.
     There are reported to be four Agni versions in production or development; Agni 1 with a range of 2,500 km, Agni 2 with a range 3,000 km, Agni 2 upgrade with a range of 3,500 km, and Agni 3 with a range of 5,000 km. A range of around 4,000 km would be required for a missile to reach Beijing from India. An Agni-2 missile was displayed in January 1999 and the first test launch was made in April 1999. Agni 2 is a two-stage solid-propellant missile. A new first-stage solid motor with a diameter of 1.8 m and carrying 36,000 kg of propellant is being developed, possibly for the Agni 3 missile, which is expected to use the Agni 2 as its second and third stages. An alternative approach would be to use a new third stage for Agni 3, either liquid or solid propellant. An improved optical or radar terminal phase correlation system has been developed to provide greater accuracy. The terminal guidance option could be retrofitted into existing Agni 1 missiles.
    There are unconfirmed reports that India is considering the design of an inter-continental range ballistic missile system named Surya, building on the experience of Agni and using the developed Augmented Satellite Launch Vehicle (ASLV) as its basis.

Unmanned Aerial Vehicles


India has successfully test-flown an upgraded version of its Lakshya unmanned aerial vehicle, or UAV.

Scientists from the Indian Defense Research and Development Organization, who developed the Lakshya, launched it Feb. 6 at the Integrated Test Range at Chandipur in Orissa’s coastal Balasore district, the Indo-Asian News Service reported.

The Lakshya is a subsonic reusable system remote-controlled UAV for air-to-air and ground-to-air firing practice and is designed to help train pilots and air defense personnel in engaging targets. The Lakshya was inducted into the Indian Air Force in 2000. The Navy and the Army also field Lakshyas.

The Lakshya has a range of 370 miles, a flight ceiling of 29,504 feet and a maximum speed of Mach 0.8. In 2003 India began to develop a battlefield reconnaissance version of the drone.

The drone test at the Integrated Test Range included the Lakshya in an air defense exercise to test the UAV’s accuracy in different environments.

Israel has purchased several Lakshya drones

BRAHMOS is a Supersonic Cruise Missile that can be launched from submarine, ship, aircraft and land based Mobile Autonomous Launchers (MAL). The missile is launched from a Transport-Launch Canister (TLC), which also acts as storage and transportation container.

Primarily BRAHMOS is an anti-ship missile. It has the capability to engage land based targets also. The missile can be launched either in vertical or inclined position and will cover 360 degrees.

The BRAHMOS missile has identical configuration for land, sea and sub sea platforms. The air-launched version has a smaller booster and additional tail fins for stability during launch.

OPERATIONAL SCENERIO

The Trishul (Trident) is a short range, quick reaction, all weather surface-to-air missile designed to counter a low-level attack. It has been flight tested in the sea-skimming role and also against moving targets. It has a range of 9 km and is fitted with a 5.5 kg HE-fragmented warhead. It's detection of target to missile launch is around 6 seconds. The missile can engage targets like aircraft and helicopters, flying between 300 m/s and 500 m/s by using its radar command-to-line-of-sight guidance. It operates in the K-band (20 - 40 GHz), which makes it difficult to jam. In the K-band three-beam system, the missile is initially injected into a wide beam, which then hands it over to a medium beam, which passes over to a narrow beam, guiding it to the target.
