CAN INDIA DEFEND ITSELF? THE DAWN OF PAKISTANI STRATEGIC BALLISTIC MISSILE part 1 The Threat

2017-02-08T10:42:00.004-08:00

From the beginning of the era of development of the missiles technology, Pakistani ballistic missiles have been the pain in ash* to Indian strategic planners.Threats of strategic ballistic missiles from its naughty neighbor are increasing day by day.So the real question is that can India defend itself from this kind of growing threat which is growing exponentially? Let's try to answer this question by analyzing the threats of Ballistic missiles and capabilities of young ballistic missile defense system, which is currently in development under the aegis of DRDO.

THREAT:

LEVEL 0 (No Threat): In threat level-0 I would like to suggest some false threat of Paki Battlefield range ballistic missile (BRBM) threat. These type of missiles are having very short range and especially in the case of Pakistani missiles they are unguided, liquid fueled and obsolete in every aspect. However, without any hesitation, Paki media and defense spokesperson continuously keep trolling.These missiles are told be capable of carrying tactical nuclear warhead but their range is very less even they are not comparable to Indian Pinaka mark-2 version which India consider as a simple rocket.If you are thinking about what is a ballistic missile to Pakistan? If you are thinking of artillery rocket then still you are wrong because they are inferior to them also, not only in term of accuracy but also in their range too.To use these missiles in case of war with India they would need to be very close to the Indian border and I believe it will be very intimidating to Indian strike fighters like Jaguar, Mirage 2K and even to our newly crafted Tejas.So ultimately they would be destroyed before they see action in the battleground.I am not sarcastic however, I would like to announce the name of honourable contenders who comes in false threat category, so behold the first contender is .......

HAL LIGHT COMBAT HELICOPTER :THE Asiatic lion

2015-09-13T11:11:00.001-07:00

Most of the Indian conflict vulnerable borders are surrounded by the mountains.There is a very high probability of conflict in those high altitude areas.This anticipation was enforced by Pakistani infiltration during Kargil war in which many soldiers martyred because of non-availability of a suitable combat helicopter for high altitude.Indian air force heavy attack helicopters were not able to fight in those high altitude areas neither attack aircraft.These things lead to a need for a combat platform which can fight in extreme high altitude, that is why the light combat helicopter development program born.HAL started a development program to use the technology available that in its advanced light helicopter and use that platform for further evolve into a light combat helicopter that can really be effective at high altitude.

Hal RWR&DC started developing light combat helicopter in 2006 and IOC is anticipated in 2016.LCH is being developed as a narrow fuselage tandem seat configuration.LCH consist of a fully digital glass cockpit in which pilot occupies the front seat and rear seat is for weapon system operator.pilot itself operate the gun turret with the help of helmet mounted sight.LCH avionics contains multifunction lcd displays, radar warning receivers, laser warning receiver and maws system.MAWS system is being provided by SAAB of South africa. It also has countermeasure (FLIR) and electro-optical sight and targeting for fire control and are synched with helmet mounted display.with the help of helmet mounted display pilot can engage any target by just merely looking on it.LCH is equipped with data link for net-centric warfare which increases its combat effectiveness in multi-folds by sending and getting information with air platform and ground-based platforms.LCH is powered by two Shakti turboshaft engine which produces 1067 kW power individually.Shakti engine is designed and produced by Turbomeca and HAL jointly, it is also known as Ardiden 1h.Shakti engine allows LCH to operate at an altitude of 6500m with full combat load.Shakti engine also features full authority digital engine control which increases the reliability of the engine.

LCH will be heavily armed with the various type of weapons those will include anti-tank missile, gun mount and air to air missile etc.LCH has four wing station for weapons. It has been confirmed that DRDO developed HELINA anti-tank missile will be used for its primary anti-tank weapon.HELINA will be integrated with a dual packed launcher.HELINA is the helicopter launch version of the Nag missile.It features a high resolution imaging infrared (IIR) seeker and effectively work in the high-temperature zones also.It has two modes of firing LOBL(lock on before launch) and LOAL( lock on after launch).IT has a range of 8 km which will provide a good standoff distance from the MANPADS which are the worst nightmare for any low flying aircraft.LCH will be armed with mistral air to air heat seeking missile and has a range of 6 km and will be primary air to air weapon for LCH.

there are following roles can be performed by LCH

Air Defense role against UAVs and slow moving aircrafts
Destruction of Enemy Air Defence (DEAD) Operations
Escort to Special Heliborne Operations (SHBO)
Offensive employment in urban warfare, CSFO (Counter Surface Force Operations) and CI (Counter Insurgency) operation.
Support of Combat SAR Operations
Antitank role
Scout duties

so far HAL has produced three prototypes of LCH

1.TD1

TD1 is the first prototype of LCH and is not weaponised.TD1 made its maiden flight in 2010.It has been extensively used for flight testing.Success of the TD1 lead to the evolution of TD2.

2.TD2

TD2 is the second prototype featuring a substantial weight reduction made its first flight in 2011 and previously it was shown in Aero India 2011 with its weapon station loaded with rocket pod and four helina anti-tank missile in a digital camouflage.

3.TD3 td3 made its first flight in 2014 and has a better-protected cockpit against ground fire and also have some improvement which were desired by Indian air force and Indian army.IT has recently completed high-altitude hot weather tail and set a record for the combat helicopter to land on high altitude forward base.A total of 65 and 114 LCH is on order for Indian air force and army.IT is revealed by Hal that LCH will be series produced from 2017.

THE DAWN OF INDIAN CRUISE MISSILES PART 2 : NIRBHAY

2015-08-06T02:51:00.002-07:00

India had always a need for long-range cruise missiles for attacking strategic and tactical targets.But India has no options rather than to develop its completely indigenous cruise missile because of missile technology control regime treaty signed by Russia also known as MTCR.MTCR blocked India from getting technologies for its long-range version of Brahmos missile from Russia.The result of these events was the development of Indian long-range subsonic cruise missile named as Nirbahay (meaning fearless).Nirbhay is being developed as all weather multiple platforms launched cruise missile.It will see service in the Indian army, air force and navy in near future.there is a plan for the development of land attack version launched from aircraft also known as (ALCM), seaborne and surface launched.DRDO which is responsible for developing this missile is also planning to develop a long-range anti-ship version of the missile with the ability to be launched from aircraft, coastal launchers and ship.
Nirbhay will weight around a ton with its solid stage booster.it will be high subsonic all the path, unlike Brahmos which is supersonic all the way.Nirbhay is powered by a small turbofan engine and for initial take off it uses solid stage booster.it will have better range compared to that of the Brahmos thanks to its turbofan engines, which consumes very less fuel compared to ramjet engines.turbofan consumes a far less fuel compared to rocket engine which is conventionally used on many of the cruise missile around the world.Mid course guidance of the missile will be provided by indigenous Ring Laser Gyro Scope (RINS), which is very accurate and can work as a stand-alone guidance systems or in conjugation with satellite navigation system in hybrid configuration.The inertial navigation system of Nirbhay operates in hybrid mode for better accuracy.Nirbhay will be provided with terrain hugging navigation system which uses TERCOM.TERCOM is in development and will be tested soon by drdo, TERCOM stands for terrain countermeasures.In future, it may be equipped with a terminal active radar seeker for better accuracy.The development of the active radar seeker for the cruise missile are in development once developed, it will pave the for development of the anti-ship version of Nirbhay.Nirbhay can be armed with both conventional and the nuclear warhead.
Nirbhay has been tested two times till now by drdo.The first test of the missile was held in 2013 which was a partial success. According to officials of the DRDO , there was a minor fault in the inertial navigation system which causes the missile to deviate from the path.After deviation from the path, drdo triggered the self-destruction mechanism onboard the missile.Apart from failure, the clean separation from the ejector, separation of solid stage booster and deployment of the wing was demonstrated in the first launch.The second test of the missile was taken place in October 2015 which was a copybook success according to the drdo.Missile completes its all designated parameter all the flight path and strikes the target with a very high accuracy.Drdo has claimed than Nirbhay will have a submeter accuracy and will have a range excess of 1200km.

THE DAWN OF INDIAN CRUISE MISSILES PART 1 : BRAHMOS

2015-07-28T12:01:00.000-07:00

BrahMos :====>

BrahMos is a joint venture between Indian defence giant DRDO and NPOM of Russia.BrahMos missile is developed by this joint venture.In this joint venture India and Russia have
50.5 and 49.5% respectively.It is an excellent example of Russian and Indian collaboration in defence and extraordinary success of BrahMos is a reflection of Indian and Russian friendship.Russia is a most important friend of India after the soviet and its collapse.BrahMos has an official range of only 290km because of mtcr treaty of Russia.
BrahMos is world's only supersonic cruise missile in the service with the armed forces.It is based on the deadly P800 onix cruise missile with the considerable upgrade.Solid stage booster and liquid ramjet engine powers the missile for a sustained supersonic flight throughout the whole path.solid state booster provides BrahMos initial acceleration for lift off at fly the missile to enough altitude and velocity so that its ramjet engine gets start.After solid stage burnout, it gets detached from the BrahMos and afterwards BrahMos is powered by its powerful air breathing ramjet engine.Ramjet engines uses ram of air for its combustion and thus does not require internal oxidizer and also it is more efficient than conventional rocket engine thus provide a greater range and reliability.BrahMos has a 300 kg of a high explosive warhead for the antiship variant.BrahMos has many variants with active service in the Indian navy and Indian army.Indian army has block 1, block 2 and block 3 with supersonic dive capability is in service.

ANTI-SHIP VARIANT:

An anti-ship version of BrahMos missile is already in service with the Indian navy. there is two type of launcher of Brahmos missile on Indian navy ships, enclined launcher on ins Rajput class ships and vertical launching system on the rest of the warships.Installation of the brahmosh missile on the Indian navy warships makes them most fearsome antiship weapon system of the intire world.there is no missile with the capability to match speed, range and accuracy and reliability.None of the existing warships anti-missile defence systems can counter the BrahMos missile.Brahmos 3mach speed and sea skimming give the very little amount of time to counter it and CIWS are almost obsolete against it.Countering of Brahmos becomes almost impossible thanks to its supersonic manoeuvres around its target.There is some hope with its countering by using AWEC aircraft and detect it early and try to intercept using long-range anti-missile weapons like SM2.

BrahMos' anti-ship variant has a range of 290km in the high low profile of flight and around 125 km in the full sea-skimming flight profile.BrahMos' anti-ship variant only differ from its ground attack in terms of the terminal seeker.This version uses active radar homing to identify and destroy the target in terminal phase.mid course correction is provided by GPS, GLONASS.Recently RCI imirat a lab of DRDO has developed G3OM system which introduces a new guiding system by utilising GPS, GLONAS and GAGAN data.this system is designed to be completely produced as a chip also called as a system on a chip.

list of Indian navy vessels armed with Brahmos:
1.ins Rajput -- 4 missiles
2.ins Ranvir -- 8 cell UVLS
3.talwar class frigates -- 8 cell UVLS
4.Kolkata class destroyers -- 2*8 cell UVLS

FUTURE of indian navy part 5: Kalvari class(scorpion) SSK

2015-07-27T09:51:00.001-07:00

Kalvari class submarine commonly known as scorpion or project 75 (p75) submarine is a diesel-electric attack (SSK) stealth submarine of the Indian navy, which is under construction at Mazagon dock limited.It was a part of Indian navy 30 years of the expansion plan.the tender for same was floated in 2005 and scorpion was chosen as the winner of that tender.A total of 6 scorpion subs are being constructed at Mazagon dock limited at a cost of 3 bn $ out of which first submarine ins kalvari was launched on April 6, 2015, and which will be commissioned at the end of 2016, rest of the kalwari class submarines will be commissioned on the yearly basis .Scorpion subs have modular state of the art design which will dramatically improve the capability of the Mazagon dock limited in terms of submarine construction. Scorpion is designed by DCNS of France and Navantia of Spain.It is designed to achieve a high degree of stealth with offensive anti-sub and anti-surface weapon carrying capability.It weighs around 1600 tons submerged and can carry heavy weight torpedoes and anti-ship missiles.Scorpion has a version with MESMA AIP (air independent propulsion) which increases its underwater diving time by almost twice.
Indian navy's version of scorpion named as Kalvari does not have AIP, but it has a larger length than Chilean version.Brazil has also ordered scorpion with AIP which will have little more displacement than its Indian counterpart.Let's stick with the Kalvari,I t has also special features.kalwari class subs will have six 533mm torpedo launcher which can also fire Exotec anti-ship missiles.kalwari will have Black shark heavyweight torpedo which has a very large radius of action,a better counter-counter measure system which allow the Black shark to engage Target without getting confused by decoys at large ranges.SM-39 Exocet anti-shipping missile has a range of 50kms against surface combatants.SM-39 is well battle proven, very reliable anti-ship missile from MBDA which will give a edge to Indian scorpion.DRDO of India has developed an indigenous air independent propulsion system based on methanol which will produce oxygen from methanol.This AIP system will be installed on the last two of the scorpion submarine which will improve the submerging time of the Kalwari sub by many folds.This system will also be installed on the rest of the Kalwari class subs latter may be in the mid-life upgrade.

CONFIGURATION :

Combat system :SUBTICS

SONAR: Long range passive cylindrical array and an active sonar

Crew:31

Propulsion : two diesel engine providing 1250kw

INDIAN AEGIS- VISAKHAPATNAM CLASS DESTROYER (P15B)

2015-07-22T12:27:00.001-07:00

India has recently launched the lead ship of its newest destroyer naming ins Visakhapatnam.Visakhapatnam class destroyer will be the future aegis like destroyer of Indian navy.Visakhapatnam class under the project name p15b in earlier it was rumoured to be named as Bengaluru class but after the launch of the first ship of this class the official name of p15b is identified as Visakhapatnam.There is an order of 4 Visakhapatnam class destroyer was placed to the Mazagon dock limited out of which one ship has been already launched in April 2015. Project 15b will feature an improved mast for its main radar.Vishakhapatnam class will have redesigned superstructure and will have a significant change in a mast.It will have better roll stability and can manoeuvre at high sea and high speed.The displacement of Visakhapatnam class destroyer will be around 7200 tons, almost equal to the Kolkata class ships.The hull of Visakhapatnam class will be same as that of Kolkata class.It can be observed that there is no major redesigning has been done which reduces the cost per destroyer and also the timeline of delivery has been shrunk.
Visakhapatnam class and Kolkata class destroyer both do not use its full space available for weapons, therefore, there is huge opportunity for upgrades in future.Kolkata class has 32 cell for barak8 surface to air missile and 16 cell universal vertical launcher for anti-ship and land attack cruise missile till now it is not specified that the Visakhapatnam class will have same or more weapons as that of the Kolkata class.It may be possible that may have 32 more vertical launchers at the aft of the ship.The Chinese counterpart of the Kolkata class, Type 52D carries 64 universal vertical launchers but has the less space available for the weapon . A question arises when we compare both warships that why Indian warships are lightly armed, answer is Indian ships are definitely going to get a heavy upgrade in their weaponry and may have long-range surface to air missiles developed by DRDO.Kolkata and Visakhapatnam both carries two ASW or multi-role helicopters thus giving an edge in anti-submarine warfare over type52 destroyer of china.It will have a longer range naval gun than Kolkata class, newer will have a 127mm gun whereas Kolkata class has 76mm SRGM.

Future Of Indian Navy : 2.Kamorta Class Corvette

2015-07-21T04:04:00.000-07:00

INS Kamorta is first indigenously developed anti-submarine warfare corvette by India under the project name p 28. ins kamorta is designed by the Indian navy and GSRE (garden reach shipbuilders and engineering ) has done the detailed design. Kamorta class ships will be vital for Indian navy thanks for increasing Chinese navy's increasing submarine force and mass manufacturing of newer diesel-electric and nuclear-powered subs ( SSN ) by China.It is very clear that Indian navy is giving priority to ASW ships and submarine, therefore, there is a plan for future variant as well which may get advanced stealth features and weapon systems and eight of those are anticipated.
Kamorta class ships are a great stride in the indigenous development of naval ships.She has a composite superstructure providing higher strength to weight ratio and stealth characteristics.Its hull is made of indigenously developed steel.This steel was developed by dodo's material research laboratory and being produced by SAIL Bhilai plant.It was also used in the production of the first carrier made in India INS Vikrant.Kamotra incorporates more than 90 % of is its components made in India.
Kamorta class operate drdo developed radar name Revati. It is the naval version of the radar developed for early warning in Akash air defence system naming 3D central acuition radar (CAR).it has a range more than 200 km for aircraft size targets and have many naval mode for better performance in high seas. Its main defence system Kavach was also developed by drdo and provide all around protection by the means of decoys and countermeasures.

Design :

Kamorta class ships are designated as corvette but she has a displacement same as the most of the frigates around the world.ins Kamorta has X-shaped hull improving underwater stealth capabilities and a stealthy superstructure made of composites this is why it is Indian navy most stealthy warship.Kamorta has CODAD (combined diesel and diesel) propulsion systems. Diesel engines are provided by France company Pielstick. Her diesel engines are raft mounted and designing of the gearbox is helped by DCNS which is also a shipbuilding company of France. Her gearbox is produced by ELCON. She has 16 cell vls system for Barak 1 and srgm oto bareda 76 mm gun mounted on the front and two rocket launchers are also placed but there is no anti-ship missile even if there is a lot of space available for the same.she is equipped with HUMSA NG next generation panoramic sonar and will be equipped with ALTAS towed array sonar.ALTAS is currently in development phase.

Armaments :

2 RBU 6000 rocket launcher

Kavach decoy system

HUMSA NG sonar

ALTAS towed array sonar

16 cell vertical launcher for Barak 1

2 AK 630 CIWS

OTO Breda 76 mm SRGM

P17A sucesser of shivalik class multirole frigates of Indian navy

2015-07-18T14:11:00.003-07:00

P17A class frigates will be the succeeder of the Shivalik class (P17) frigate of Indian navy.P17a will have improved design in terms of stealth and weapon system.they will have better radar and offensive weapon like Brahmos in vertical launching system and most probably p17a will be equipped with Nirbhay land attack cruise missile.If anti-ship version will be developed of the Nirbhay then these ships may get installed with the Nirbhay.As the first ship will come after 2022 there may be possibility of getting hypersonic version or mini version of Brahmos.they will be equipped with Barak 8 missile which will soon go to the trail in this monsoon on the INS Kolkata.Barak8 has the very good anti-missile capability and also very effective against the airborne already has been installed onboard the ins Kolkata.MFSTAR radar will reduce the number of radars required for the P17A as compared to Shivalik class.MFSTAR operates in S-band and can track aircraft from a distance more than 250 km and guide many missiles simultaneously.It can also track sea-skimming missiles from a distance of 25 km. P17a will have very high automation and thus reducing the number of sailors required only 150 as there were 250 in the case of the Shivalik class.As P17a is upgraded Shivalik class ships many of the features will be the same like 6000 tonnes of displacement,x shaped hull and hanger but will be rail-less.
P17a is designed for modular construction and will be made by the modular construction method.modular construction will allow shipyards to build the frigates faster.GSRE and Mazagon dock has been chooses by the navy for construction.GSRE will build three and rest of four will be constructed by Mazagon dock.these shipyards have been given a time period of 24 months to equipped with the modular construction facility.Construction will start in 2017 and all the ships will be delivered by 2025.This project is costing up to 10 billion $.After this project, India will have two shipyards with the capability to build world class frigates.

2014, has been prepared for submission to the President of India under Article 151 of the Constitution of India.

The Report contains the results of examination by Audit of the issues relating to Design, Development, Manufacture and Induction of Light Combat Aircraft (Air Force). The Performance Audit (PA) covers the progress made in execution of LCA programme since the last Review, i.e., Para 28 of the Report No. 8 of 1999 of the C&AG of India, Union Government, Defence ServicesIndian Air Force (IAF) was operating MIG-21 series of aircraft manufactured during 1966 to 1987. Majority of these aircraft were to complete their total technical life and were expected to be phased out in the 1990s, thereby resulting in significant fall in combat level of Air Force. Thus, IAF mooted the proposal (early 1980s) for a replacement aircraft for MIG-21 fleet. It was against this backdrop that the indigenous design & development of Light Combat Aircraft (LCA) was sanctioned (1983) and Aeronautical Development Agency, Bangalore was formed (1984) to execute the programme.

As specified in the ASR (1985), LCA was required to be inducted into IAF by 1994. However, the LCA programme was riddled with delays right from the sanction of 1983 and even after three decades since, LCA is yet to be inducted into IAF squadrons.

During the course of phased development, ADA’s decision to advance building of two prototypes from FSED Phase II to FSED Phase I rendered these prototypes deficient of critical on board systems, which had a cascading effect on the remaining three prototypes, and led to ADA using even the Limited Series Production aircraft meant for IAF use towards flight testing/evaluation, in contravention to the commitment given to the GoI at the time of obtaining sanction for building of these aircraft.

Further, IOC for LCA Mark-I was achieved (December 2013) with 53 concessions/permanent waivers, which limits the operational efficiency and survivability of the aircraft. Consequently, LCA Mark-I currently under development (both IOC/FOC aircraft) has shortfalls in meeting the engine thrust and other parameters such as weight of the aircraft, fuel capacity, pilot protection from front against 7.62 mm bullets etc. The self-protection jammer which was originally to be fitted on LCA Mark-I is now planned to be fitted on LCA Mark-II, thus the 40 LCA Mark-I would be provided only with RWR Tarang-1B and deficient of self-protection jammer, thus limiting its electronic warfare capabilities. Thus, IAF would be constrained to use 40 LCA Mk-I aircraft with limited operational capabilities, and LCA Mark-II being developed by ADA presently is expected to meet the ASR.

Delays in identification/replacement/ addition of weapons by IAF and their integration as per IAF requirement to make the LCA contemporary also added to the delays. In addition, there have been delays in completion of work packages by various work centres, which indicated ineffective monitoring of the project by MoD.

User involvement right from inception would be essential for effective and efficient completion of any project However, active user (Air HQ) participation in the LCA Programme started only after November 2006, even though the need for a Liaison Group between Air HQ and ADA to ensure closer interaction between the design team and the user for better appreciation of mutual perception, had been recommended by the LCA PDP Review Committee as early as in 1989.

Though ADA claimed achievement of 70 per cent indigestion, half of these sub-systems are developed with imported electronic components and accessories etc. The LCA programme suffered major setbacks in the indigenous development of Kaveri engine, Multi-Mode Radar, self-protection jammer, etc. The proposal for indigenous development of 109 LRUs was pending approval since February 2014.

The setting up of a production capacity of eight LCA per annum was delayed by HAL, which coupled with delay in production capacity augmentation, had impacted the formation of LCA Squadrons. Further, there has been delay in the manufacture and supply of series production aircraft due to delayed LCA development.

As a consequence of delay in development and induction of LCA, IAF had to up-grade MiG Bis, MiG-29, Mirage-2000 and Jaguar aircraft at a cost of `20,037 crore and revise phasing out of MiG-21 to ensure credible combact .

Considering that measures taken by IAF to upgrade other aircraft were of temporary nature and induction of LCA was crucial for maintaining the operational preparedness of IAF in order to overcome the drawdown of squadron strength permanently, the LCA programme needs to be expeditiously completed to cater to the needs of the Defence Forces so as to avoid import of the fighter aircraft of this class and to ensure self-reliance in the long run.

Indigenous Missiles (Air Defence) At A Glance

2015-04-24T14:44:00.000-07:00

Indigenous air defence missiles include Akash, AAD, PAD, PDV, Maitri and Barak 8.Surface to air missile is also called as SAM.We are still behind many countries like US, UK, Russia,France and also from china in the development of sophisticated SAMs, but the success of Akash missile program gave DRDO the confidence to build the sophisticated SAMs.
there are some images of Indian sams

Akash Missile

Advance Air Defence (AAD)

PDV Missile Barak 8

SR sam (MAITRI)

Akash Missile

Design:

Akash missile has four clipped triangular wings are attached to the mid body of the missile.these four wings control its yaw and pitch of the missile.It has four ducts for its engine in the mid-body as you can see in the above image.It has four clipped delta wing to control the roll of the missile.
Propulsion: Akash uses indigenous integrated solid state ramjet engine for its propulsion.Ramjet engine allows Akash missile to goes up to 2.5 Mach speed, it also provides acceleration whole path until the interception.The whole way thrust ensures higher manoeuvrable compared to rocket-propelled SAMs like S 300, Patriot etc.

Guidance: Akash missile uses command guidance provided by its fire control radar.

Its fire control radar is Rajendra. Rajendra is a phased array radar which has a range of 60 km. It can track 64 targets and engage 4 simultaneously in ripple mode.This radar provided tracking to interception information through a data link to the missile.It has also a good ECCM feature which allow to work in highest jamming environment .this is being produced by the BEL.
Accuracy: Akash missile has very high single shot kill probability around 88%.If two missile are fired in ripple mode then its kill probability will be around 98.5%.
Akash is a very decent sam and it costs half of the comparable systems around the globe, it is being produced by BDL for IAF and for IA will start soon.its mk2 version is also being developed by DRDO and thus making this missile a complete success.

BMD phase 1:

Our ballistic missile defence system (BMD) is a two-tier system, which include an

exo-atmospheric interceptor missile and an endo-atmospheric.this program started in 1999 due to the

Pakistani nukes carrying ballistic missiles and also due to our no first use of its nuke policy.

Advanced Air Defence (AAD):

AAD is the endo-atmospheric missile of the BMD system.It is a very manoeuvrable compare to exo-atmospheric version.it can intercept ballistic missile of 2000 km range at an altitude of 30km. Its fire control radar is provided by the Thales of France. the radar is aesa and DRDO program to fit into its BMD program.
AAD missile use drdo developed inertial navigation system and midcourse guidance by the fire control radar.It use an active radar seeker for terminal navigation or end game.it use single stage solid state rocket propulsion.It is very reliable because it had intercepted the target without any failure in the past tests.

Prithvi Air Defence(PAD):

PAD is a two stage exo-atmospheric anti-ballistic missile.It uses solid state propellant in fist stage and in second it uses liquid propellant. It is capable of intercepting the ballistic missile of the class of 2000 km range at an altitude of 80 km.

Its fire control radar is long-range tracking radar( LRTR) used in the green pine system of Israel, its software is developed by drdo and named as Swordfish .the radar act as tracking and fire control system.it can track up to 600 km.PAD uses same navigation and seeker that is used in

AAD.

Let's talk about the whole of the BMD system, the interception of the ballistic missile require network-centric control centre connected to spy satellite and an autonomous interception.All the required technology is developed by DRDO.

Barak 8:

Barak 8 is a joint development venture between DRDO and IAI.It is a light weight medium range surface to air missile of range 70 km.It can destroy enemy missile, low altitude flying cruise missiles,
aircraft at long ranges.It uses dual pulse solid state motor developed by drdo.Its fire control radar is
MFstar radar developed by Elta of Israel.It has the two-way data link for mid-course update. At terminal
stage it uses another motor and also activates its own seeker.It is highly manoeuvrable in the terminal phase.
Navy calls the Barak 8 as lr-sam .navy is planning to install it to Kolkata class destroyer,P15b (Visakhapatnam class),P17a and also on Ins Vikrant .this missile will act as backbone of Indian navy air defence warships.Indian air force also wants to order some barak 8 sam launchers to protect its assets.

TEJAS : THE PRIDE OF INDIA

2015-04-16T17:48:00.000-07:00

Tejas is compound tailless delta wing multirole Indian fighter aircraft.
It is designed and developed by DRDO aeronautics cluster ADA(aeronautical development agency) and being produced by Hindustan aeronautics limited as per its initial operational clearance configuration.
TEJAS AS THE PRIDE OF INDIA: I love this plane not because it is beautiful, but because it is Indian (designed and developed in India), the first plane which is truly designed by Indian.It is very light and small.
It has been tested in harsh Indian condition and also proved its capability in Iron Fist, Aero India 2013
and by taking off from SBTF facility, Goa. IAF never supported fully this Desi bird.As it is first Indian combat aircraft it has some flaws, but these can be eliminated in the mid-life upgrade.
It has completed its IOC tests and near to get FOC, till now Indian Air force has ordered only 40 plane which is very less than what it should be as IAF need about 400 light weight single engine fighter.

DESIGN: Tejas is designed along the single engine, unstable tailless compound delta wing configuration.
here is the orthographic of Tejas......

As it is unstable in needs to makes stable which is done by flight control computer.As we read "it is unstable " one question arises why it is so?,what is the advantage?how does it fly smoothly as we know?

in now days combat aircraft must be highly maneuverable aircraft for air to air combat.In your views which are more maneuverable a stable car or an unstable bike , which can turn faster? the answer is bike.that is why Tejas is made astable.

Tejas flight control system is quadruplex digital fly by wire(fbw) system.Fly by wire means its actuators which control the control surface movement is controlled by electronic signals, not by mechanical means. the fbw software is made by national CLAW team and was validated, which was a big achievement.Till now Tejas had completed as more as 2800 flights without any accident , this proves how reliable its fbw system is.
Compound delta wing produces vortex as same as close coupled canard in the Gripen at a high angle of attack (AOA).Tejas fbw system allows it to go up to 28-degree angle of attack as per ADA.it can
go to 35-degree AOA without its control surfaces going to stall.
ENGINE: Tejas use American GE F404 IN 20 engine.it is a low bypass turbofan engine.
The specification of the engine is as follow
Dry thrust: 53.9 kN
Thrust with afterburner(wet thrust): 89.8 kN
With this engine Tejas has 1.07 thrust to weight ratio which is best in its class.Due to its high thrust to weight ratio and low wing loading it has high instantaneous turn rate and sustained turn rate.Its high ITR provide an opportunity to get a first lock and hence the first attack.

ARMAMENT: Tejas has 7 hard points for weapons and one for targeting pod like lightning targeting pod.

Tejas can carry 3.5 ton of weapons on its 8 hard points.the configuration of weapon is shown in above image.It can carry 1250 litre on its two inner sides of hard point on the wing and can carry 750 litres of fuel on centerline hard point.Tejas external hard points is use to carry two high off bore sight R 73 missile, which has a range of 35 km and it uses IR sensor.R 73 is main close combat missile of Tejas.
Derby and Python will be integrated on Tejas as beyond visual range missile (WVR).The Astra missile will also be integrated on Tejas. As Tejas is a multi-role fighter it can carry the iron bomb, laser guide bomb(LGB) and anti-ship missile also.Tejas main BVR missile will be I-Derby ER which has range excess of 100 km.
AVIONICS: Tejas has all glass cockpit and it has also night vision compatible.It has multi-function display for showing information, head up display(hud) for displaying important information it allows
pilot to fly without any need for seeing around in cockpit.tejas has an electronic warfare suit for better survivability.It includes radar warning receiver, automatic flare and chaff launcher.In future, it may be outfitted with the radar jammer also.
Tejas has a multi-mode radar (MMR) which is developed from elta m2032 radar.the radar antenna is indigenous but is processing end is developed by Israel.its range is said to be about 100km for fighter size aircraft(RCS of 5m2).The radar has sub air to air mode , air to the ground mode or sar mapping mode and air to sea mode.it can track sea targets from 300km away.
RANGE: Tejas is lightweight fighter its so combat radius is little less than medium weight fighter aircraft.
combat radius :700 km (approx)
ferry range: 3000km

LCA NAVY: N- LCA:

There is a separate program along with the IAF Tejas to develop a naval carrier-borne fighter on the basis of the Tejas platform. It has a stronger landing gear for carrier operation.it has leading edge vortex controller (LEVCON),it helps naval Tejas for better low-speed handling and , approach speed and sink rate for arrested landing.there is plan for 5 naval prototypes out of which 3 will be mk1 and two mk2.NP1 had taken off from shore-based test facility , Goa last year end.with that event India becomes one of the elite countries to develop its indigenous carrier-borne fighter.

TEJAS MK 1 P (mk 1.5):-

HAL has purposed air force with an improved mk1 of Tejas with improved avionics. According to HAL this version may be available for production from 2017 , this version will have downscaled

elta m 2052 radar and electronic warfare suit which is being developed for the Tejas mark 2. these upgrade will make Tejas best BVR fighter plane in the lightweight category.
