Design

The version is equipped with SAAB supplied Integrated Defensive Aids Suite (IDAS) with Electronic Warfare self-protection which is fully integrated into the modern glass cockpit.

ALH-WSI has undergone integration trial for armament and electro-optical systems.

A final round of weapon firing trials is scheduled in September 2011, starting with its 20-mm turret gun, followed by trials of its 70mm rockets and MBDA Mistral air-to-air missiles in November.

Initial Operational Clearance (IOC) is expected by late 2012 with deliveries of the production helicopters starting on or before 2013.

As per the initial orders, close to 70 Rudras are to be supplied to Indian armed forces. “It has comfortably-exceeded the payload and performance requirements at 6 km height. It has integrated sensors, weapons and electronic warfare suite using an upgraded version of the glass cockpit used in the Mk-III. The cockpit avionics is a state-of-the-art technology when it comes to helicopters. The sensors include stabilised day and night cameras, Infra-Red imaging, as well as laser ranging and designation,” sources said.

HAL Rudra can carry self defence systems including radar & missile detectors, IR jammer, chaff & flare dispensers.

All these systems have been tested individually.

Overview

The KALI is not a laser weapon as commonly believed. It emits powerful pulses of electrons (Relativistic Electron Beams- REB). Other components in the machine down the line convert the electron energy into EM Radiation, which can be adjusted to x-ray (as Flash X-Rays) or microwave (High Power Microwave) frequencies.

This has fueled hopes that the KALI could, one day be used in a High-Power Microwave gun, which could destroy incoming missiles and aircraft through soft-kill (destroying the electronic circuitry on the missile). However, weaponising such a system has many obstacles to overcome.

History

The KALI project was first mooted in 1985 by the then Director of the BARC, Dr. R. Chidambaram. Work on the Project began in 1989, being developed by the Accelerators & Pulse Power Division of the BARC. (Dr. Chidambaram was also the Scientific advisor the Prime Minister, and the Chairman of the Atomic Energy Commission). DRDO is also involved with this project. It was initially developed for industrial applications, although defence applications became clearer later.

The first accelerators had a power of ~0.4GW, which increased as later versions were developed. These were the KALI 80, KALI 200, KALI 1000, KALI 5000 and KALI 10000.

The KALI-5000 was commissioned for use in late 2004.

Design

The KALI series (KALI 80, KALI 200, KALI 1000, KALI 5000 and KALI 10000) of accelerators are described as “Single Shot Pulsed Gigawatt Electron Accelerators”. They are single shot devices, using water filled capacitors to build the charge energy. The discharge is in the range of 1GW. Initially starting with 0.4GW power, present accelerators are able to reach 40GW. Pulse time is about 60 ns.

The Microwave radiations emitted by the KALI-5000 are in the 3–5 GHz Range

The KALI-5000 is a pulsed accelerator of 1 MeV electron energy, 50-100 ns pulse time, 40kA Current and 40 GW Power level. The system is quite bulky as well, with the KALI-5000 weighing 10 tons, and the KALI-10000, weighing 26 tons. They are also very power hungry, and require a cooling tank of 12,000 liters of oil. Recharging time is also too long to make it a viable weapon in its present form.

Applications

The KALI has been put to various uses by the DRDO. The DRDO was involved in configuring the KALI for their use.

The X-rays emitted are being used in Ballistics research as an illuminator for ultrahigh speed photography by the Defence Ballistics Research Institute (DBRL) in Chandigarh. The Microwave emissions are used for EM Research.

The microwave-producing version of Kali has also been used by the DRDO scientists for testing the vulnerability of the electronic systems of the Light Combat Aircraft (LCA), which was then under development.

It has also helped in designing electrostatic shields to “harden” the LCA and missiles from microwave attack by the enemy as well as protecting satellites against deadly Electromagnetic Impulses (EMI) generated by nuclear weapons and other cosmic disturbances, which “fry” and destroy electronic circuits. Electronic components currently used in missiles can withstand fields of approx. 300 V/cm, while the fields in case of EMI attack reach thousands of V/cm.

As a Weapon

The KALI’s potential for a military role as a beam weapon has made it, in the eyes of China a threat. However, weaponisation of the KALI will take some time. The system is still under development, and efforts are being made to make it more compact, as well as improve its recharge time, which, at the present, makes it only a single use system.

There are also issues with creating a complete system, which would require development of many more components. There have been reports of placing the weaponized KALI in an Il-76 aircraft as an airborne defence system. There is also speculation of using the KALI as an Anti-satellite weapon and as a space-based weapon system, although it is unlikely that they would be implemented, given India’s stance on those issues.

                                    K-15 SLBM  The K family of missiles is a series of submarine-launched ballistic missiles (SLBM) developed by India to boost its second-strike capabilities and thus the nuclear deterrence. Information about this family of missiles has mostly been kept secret. In November 2010, India Today featured an article named “The secret ‘K’ missile family” that gave away some details about what they called as the “Black Project” which DRDO officials are covertly working on. It further stated, “The top secret indigenous “K” missiles are faster, lighter and stealthier.”

Missiles in the series

K-15 or Sagarika

Range Vs Payload for Shaurya Missile.

The Sagarika/K-15 missile (Sanskrit: सागरिका, IAST:Sāgarikā, meaning Oceanic) is the SLBM version of the land-based Shaurya missile. With a shorter range than K-4 missiles it is to be integrated with Arihant class submarine concurrently developed for the use of Indian Navy.

Sagarika/K-15 was developed at the DRDO’s missile complex in Hyderabad. The complex consists of the Defence Research and Development Laboratory (DRDL), the Advanced Systems Laboratory (ASL) and the Research Centre, Imarat (RCI).

DRDL designed and developed the missile, while the ASL provided the motors and propulsion systems. The RCI’s contribution was in avionics, including control and guidance systems and inertial navigation systems. K-15 has a range of around 700 km with 1,000 kg warhead and around 1,900 km with 180 kg warhead. This will also get help from Indian Regional Navigation Satellite System (IRNSS), expected to be ready by 2014, to ensure guaranteed national access to precision navigation. These will enable high accuracy required for precision strike.

K-4 Missile

K-4, named after former President of India Dr. APJ Abdul Kalam, is the next significant development under the K-X series by DRDO. It was covertly tested off the coast of Visakhapatnam in January, 2010. However, any detail regarding the developments in this project are confidential and this project is sometimes referred to as “BLACK PROJECT” whose existence is neither denied nor acknowledged by DRDO. While there are some reports that claim that K-4 is a submarine launched version of AGNI-V, other reports state that it is actually a SLBM Version of the Agni-III missile that is being worked on. The goal of this project is to expand the second-strike options for the country, DRDO scientists told reporters during a briefing. A total of 258 private firms and 20 DRDO laboratories were involved in this venture. The Missile is said to have two variants. One with a range of 3,500 km that is 10 m long and the other with a range of 5,000 km will be 12 m long to arm future nuclear submarines of the Arihant class. K-4 will provide India the capability to target China and Pakistan simultaneously. INS Arihant, first of the Arihant Class Submarines, will be able to carry 4 (10m long) K-4s or 12 K-15s.

K-5 Missile

K-5 missile is the SLBM version of AGNI-VI (ICBM) is allegedly under development by DRDO. And it will arm the future variants of Arihant class submarines of the Indian Navy. DRDO revealed in 2011 that it is also in the process of developing a variant of Agni missiles which will be a submarine launched solid fuel missile with a maximum range of 6,000 kilometers and a payload of one tonne. However, there is strong opacity regarding the existence of such a project.

DRDO rather than starting all over again the Arjun Mk.2 will have the same design of Arjun Mk.1, but major changes are planned for the new generation variant of Arjun Tank to keep up with the new technological changes which are been incorporated in the MBT’s world over.

Arjun Mk.2 will have Battle Field Management System (BFMS) which will enable the tank to get feed from UAV‘s and Helicopters, which then enable the Arjun Mk.2 tank crew much aware of their surroundings and better understanding of the battle zone, this will lead to improvement in coordinating with other Friendly tanks in the zone and also avoid Friendly kills, it will also give information regarding enemy tank movement along with their troops and help navigate terrain in the battle zone.

Self-diagnostic system (SDS) will also be added to Arjun Mk.2 which is like a health monitoring system. it will not only tell the tank crew if it is having any problem but also point out the trouble area , it is also important when Tank has taken multiple hits from different position and from different ammunition after a self-diagnose Tank crew will know exact damage inflicted on the Tank .

Arjun Mk.2 will get a new efficient 1500bhp engine which has been in development by DRDO in India its self, they are reports that a Indian Private industry is also working with DRDO on the engine development, currently Arjun Mk.1 is powered by German supplied 1400bhp engine which is quite old in design and technical parameters but still a powerful and respected engine in the world.

NERA (non-explosive reactive armor) will be added to Arjun Mk.2 this will give the tank additional protection against anti-tank munitions, unlike ERA, NERA will enable tank to take multiple hits anti-tank munitions, but also increase the weight of Arjun Mk.2 to 60 tons from its current weight (Arjun Mk.1) of 58 tons.

It is much likely that Arjun Mk.2 will also spot Air-conditioning system for the crew, which will be powered from an APU which will draw its power from the Main engine of the Tank; this will enable the tank crew to operate in higher temperature of desert heat without any discomfort to the tank crew, Arjun Mk.1 already has hardened electronics that function perfectly even in the Rajasthan summer without requiring any Air-conditioning system

The Arjun Mk.2 is to undergo summer and winter trails in 2012. If the tests are satisfactory, then the tank will be able to begin production in 2014.

FMBT

The Indian Army wants the tank to have an Identification Friend or Foe (IFF) system “to obviate chances of own tanks firing at each other in battle”, and a whole new reliable and secure mobile communication system capable of data transmission, audio and video conference. Protection in the form of soft-kill system requires IR detectors, laser warning, radar warning and devices to instantaneously integrate these signals and control a countermeasure suite. Such systems are threat specific so all would have to be carried on a vehicle to gain protection against more than one part of the EM threat spectrum.

For mobility, in order to achieve ‘extraordinary’ acceleration, the Army observes that it is necessary to seek a compact power pack in the form of a gas turbine. The Army wants an active suspension system with sensors, control units, and a hydraulic power source in combination, to automatically alter the suspension characteristics to more closely match the speed of the vehicle and the terrain profile, especially in Indian terrain conditions.

The Army says it wants a high-performance armour system on its FMBT with advanced materials incorporating the following qualities A. Reduced penetration by most lethal weapons, B. Elimination of parasitic mass leading to a weight reduction, C. Excellent corrosion resistance, D. Inherent thermal and acoustic insulation properties.
