Akash (Sanskrit: आकाश Ākāś "Sky") is India's medium range surface-to-air missile defense system developed by the Defence Research and Development Organisation (DRDO) and Bharat Electronics Limited(BEL) as part of the Integrated Guided Missile Development Program.[3][4][5] The missile can target aircraft up to 30 km away, at altitudes up to 18,000 m.[6] Akash can be fired from both tracked and wheeled platforms.[1] Akash is said to be capable of both conventional and nuclear warheads, with a reported payload of 60 kg.[2] A nuclear warhead could potentially give the missile the capability to destroy both aircraft and warheads from ballistic missiles. The missile battery is described as being able to track and attack several targets simultaneously





An Akash battery comprises four 3D phased array radars and four launchers with three missiles each, all of which are interlinked. Each radar is able to track 16 targets simultaneously and control a launcher with 3 missiles. Hence it is reported to be able to track 64 targets and simultaneously attack any 12 of those targets at one time.



The Akash system is comparable to the Patriot system, but unlike the Patriot, Akash is fully mobile and capable of protecting a moving convoy of vehicles. Like the Patriot, the Akash is really an air defence SAM which has been tested in a ballistic missile role.

Indian Twin ZU-23mm Highly portable AAA`s Possible upgrade..
The reason why Indian twin Zu-23mm need upgrade coz its optics and tech are outdated also its technique is very complex to operate beside all these it cannot operate in night..


Indian ZU-23-2
Possible Upgrade is '23 ItK 95' - Finnish upgrade, 23 ITK 95 (Zu-23MOD)
Range: 3000m. Country of origin: Soviet Union (gun), France (thermal sight), Finland (everything else)




IA AD operate these guns more than L70, So upgrading these system are Very-Important..

The Indian SAM Network


INTRODUCTION:

One of the most populous nations in the world, India has engaged in numerous regional conflicts in the past. The threat environment led to the creation of a point-defense oriented EW and SAM network designed not to protect the skies over India, but to protect the military units tasked with such a role. This ultimately led to the creation of a number of EW and SAM units within the Indian Air Force.

OVERVIEW:
Indian air defense elements, to include EW assets, SAM systems, and interceptors, are subordinate to the Indian Air Force (IAF). This allows the IAF to coordinate both sensors and weapons, allowing for a maximum degree of target deconfliction. SAM units are organized as squadrons, with radar units being organized as either signal units or transportable radar units, depending on the assigned types. These units are in turn subordinate to the five operational commands in the IAF.

The Indian SAM network follows a point defense layout. The primary SAM system employed by the IAF is the S-125M (SA-3B GOA). These systems are deployed at various airbases in the northern and western portions of India. EW assets are deployed primarily along border regions, with the highest concentration being present along the northern and western borders with Pakistan.

EW ASSETS:
Fifty four EW sites have been identified in India. The primary assets are THD-1955, P-12/18 (SPOON REST), and 36D6 (TIN SHIELD) radars. Thirteen THD-1955 radars arrayed primarily along the border region from Pakistan to Myanmar provide a significant amount of EW coverage. EW coverage is enhanced by fourteen 36D6 radar sites, arrayed primarily along the border with Pakistan. The 36D6 is significant as it can provide both target track data to SAM batteries as well as GCI support for Russian-origin fighter aircraft such as the MiG-29 (FULCRUM) or Su-30MKI (FLANKER-H). P-12/18 radar sites are scattered throughout the region, as are indigenous Indra-II radar units. The net result is an EW network that is heavily oriented towards potential threats.

The following image depicts the locations of identified Indian EW facilities. Dark blue diamonds represent basic EW sites, typically manned by P-12/18 or Indra-II radar systems, while light blue diamonds represent THD-1955 radar facilities. Blue circles represent 36D6 radar facilities. The range rings given for the 36D6 sites represent the 165 km acquisition range against a typical fighter-size target. Each radar system is capable of target detection at greater ranges depending on the target RCS and altitude, with the THD-1955 typically employing a range of 400 km.

T
he following image depicts a typical THD-1955 site. These large radars are sited atop dedicated structures. This site is located south of Shillong in eastern India.

The following image depicts a deployed 36D6 radar at Pune AB in western India. This radar likely serves as both an EW and GCI asset, given its co-location with Su-30MKI fighters.

India does possess the 40V6 series of masts for mounting the 36D6, although their use appears to be relatively infrequent. The following image from February 2008 depicts a 36D6 mounted atop a 40V6 mast assembly at Nal AB. Imagery captured four months later indicates that the 36D6 is still deployed but has been removed from the 40V6. Only thee 36D6 locations have an identifiable 40V6 series mast available for use.

Other EW assets include the A-50I AWACS based at Agra AB, and potentially an aerostat system found near the border with Pakistan. The aerostat system's purpose is unknown at this time, but could potentially be used to mount an air surveillance system. The facility can be seen in the image below.
THE S-125:

India's primary strategic SAM system is the S-125M. These systems were delivered between 1973 and 1989 from the USSR, and thirty four batteries are currently active. These batteries provide point defense for key military installations, typically airbases, in the northern and western portions of India.

The locations of India's active S-125M batteries and their engagement zones can be seen in the image below:


The S-125M has two specific drawbacks: range and single-target engagement capability. The ability of the system to engage one target per battery is partially mitigated by placing multiple batteries at many locations, but the 25 km maximum range of the system effectively reduces its role to one of point defense only, lacking the range to provide long-range overlapping fields of fire necessary for a more robust air defense network.

IAF S-125M batteries are frequently relocated in their operating areas. This can be done to complicate targeting by enemy assets and to allow systems to be cycled through maintenance periods. The following image depicts the S-125M deployment area at Vadodara AB in western India. While only one location currently has an active battery, there are four other locations which have been active at some point in the past.



Numbering the S-125M locations 1 through 5 from west to east, the following information can be derived from available imagery:

Site 1
-Active from December 2005 to March 2010

Site 2
-Active from October 2000 to October 2002
-Active from June 2003 to November 2003
-Active from December 2003 to March 2010

Site 3
-Active from October 2000 to October 2002

Site 4
-Active from November 2003 to December 2005
-Currently active as of March 2010

Site 5
-Active from June 2003 to March 2010

All told, there are twenty one inactive or former S-125M positions identified throughout India that can be used as relocation sites should the need arise.

Very nice information Sirji... But wonder how this information about exact locations of SAM's came out. It will be disadvantageous if they enemy knows this.

TACTICAL SYSTEMS

Tactical SAM systems are also operated as point defense assets in the IAF. The primary system is the Osa-AKM (SA-8 GECKO), a mobile system mounted on a wheeled TELAR. The 10 km range of the system allows it to serve as a layered short-range counterpart to co-located S-125M batteries.

An IAF Osa-AKM TELAR can be seen in-garrison near Ambala AB in the image below.


The Indian Army operates the 2K12 Kvadrat (SA-6 GAINFUL), which could be employed in a similar capacity to IAF Osa-AKM units if required. The Army also operates additional Osa-AKM units.

LIMITATIONS:
Given that India has chosen to rely on a point-defense oriented air defense network, the lack of long-range SAM coverage is not a true limitation. Furthermore, the presence of significant numbers of fighter aircraft such as the Su-30MKI cpaable of acting in concert with the EW network to perform interception tasks can alleviate the lack of long-range SAM coverage. However, there are still some limitations to be addressed within the network as it is currently organized.

The primary limitation is one of terrain. Northern and eastern India contains very varied terrain, which can introduce significant blind spots in radar or SAM coverage, reducing the network's effectiveness. The issue of EW coverage has been addressed to a degree by the procurement of the A-50I AWACS platform.

The other significant limitation faced by the strategic SAM network is one of age. While many of the systems have been refurbished or modified to retain their effectiveness, the age of the systems is such that a potential aggressor has enjoyed a significant amount of time to discern weaknesses and develop ECM systems and countertactics to defeat the deployed systems. In truth, it is the age of many of these systems that has pushed India towards developing and procuring new SAM systems to replace the elderly systems currently in widespread use.

ABM DEVELOPMENTS:
One significant aspect of Indian air defense that will become operational in the near future is an ABM capability. India began researching an ABM system in 1999, with the goal of fielding a two-tier system. The two-tier system would consist of the exoatmospheric PAD, a Prithvi SRBM derivative, and the endoatmospheric AAD. Where PAD employs a directional warhead, AAD employs a hit-to-kill kinetic warhead. It is now believed that a new weapon referred to as PDV will replace the PAD in the two-tier structure. This system is capable of engaging 1500 km range ballistic missiles, making it an ATBM rather than a true ABM system, but a separate system with a design goal of engaging 5000 km range weapons is underway to field a true ABM.

The radar syste employed by the PAD/AAD weapons is referred to as Swordfish and is in actuality a modified Israeli EL/M-2080 Green Pine radar system. Two of these radars were delivered to India in 2002. One is currently sited northeast of Bangalore, with the second being located near Konark on India's northeast coast. The radars are sited in protective domes. The inland facility can be seen in the image below:



FUTURE PROSPECTS:
India is actively developing and acquiring new SAM systems to revitalize its air defense force for the 21st Century. There are three significant programs which should begin to bear fruit in the near term. The first is the Akash, being procured by the IAF to potentially replace S-125M systems. This is an indigenous mobile SAM system derived in part from the 2K12. Maitri is a short-range SAM being co-developed with France, employing technology used in the French Mica BVR AAM. The third program is a long-range SAM system. This system may build upon the aforementioned AAD weapon under the codename of Ashvin. Deployment of these weapon systems will eventually allow the IAF to retire the S-125M and Osa-AKM, replacing them with weapons more capable of performing effectively in the current environment.

CONCLUSION:
While India's SAM network does not appear to be particularly robust or capable on paper, it is not intended to serve as the primary protector of the nation's airspace. However, even with its more limited role, modernization programs must continue if the network is to remain viable in the forseeable future.

Actually the Information is on a blog, Originally Posted by Nitesh here:

It is also Important to post it here as this thread is dedicated for Indian Air-defense..

Beside all these information on the blog Posted by Sean O'Connor, Only Shows IAF primary Air-defense and Main Radar..
He completely missed rest of the radars sites like Tinshields and other posted here..
http://www.defenceforum.in/forum/missiles-aerospace/13946-2.htm

Further, He fail to mentioned abt Army SA-6 SAM sites and Radar Sites, Therefore the title should be 'IAF SAM network' not 'INDIAN SAM network'..

Though i appreciate for his efforts..:emot112:

North-eastern Part is under IA sam & aaa control..
The poster didn't showed any detail abt Army AD..
The surveillance Radars are also under Army..
Beside all, Army have better SA-6 than SA-3..

The eastern and south-eastern coastal areas seems to have large gaps with respect to radar coverage. I hope the induction of Long range radars are speeded up and the gaps are covered.

India Nears Fielding Of New SAM Systems


The Indian air force is gearing up to field a raft of new air defense equipment and address long-standing concerns about the existing inventory.
New Delhi has long worried about gaps; and in areas where it has fielded air defense systems, the equipment is often out of date. Air Chief Marshal Pradeep Naik, the Indian air force (IAF) leader, says half of the equipment at his command faces obsolescence, with that label applying to the majority of air defense weapons.
That situation is now being remedied. By next March, the IAF will begin receiving the first of 18 Israel Aerospace Industries (IAI)-Rafael Spyder quick-reaction medium-range missile systems. The offshore deal became necessary in 2006 because of development problems and delays in the indigenous Akash surface-to-air missile (SAM) program.
However, Akash has since turned the corner, and the IAF decided to order six more Akash batteries worth $925 million—each with 125 missiles—in addition to the two systems already on order. The service will receive its first two Akash batteries in February, and is likely to deploy them in India's Northeast.
The IAF also anticipates joint development work kicking off in earnest on the 15-km.-range (9.3-mi.) Indo-French Maitri short-range SAM (SR-SAM), which is aimed at filling the void created when the Indian government decided to wind up the Trishul point-defense weapon program in 2006 and effectively de-link it from IAF and Indian navy requirements. A workshare agreement between the Indian Defense Research and Development Organization (DRDO) and European missile maker MBDA has been concluded. IAF sources suggest a formal accord sanctioning the program is likely soon, possibly when French President Nicolas Sarkozy visits New Delhi later this year.
An MBDA official says the SR-SAM would finish development work and the first phase of testing within three years of program go-ahead. While no official timelines have been revealed, the IAF expects the system to be available for deployment by late 2013.
Even higher on the IAF's priority list is the 70-km.-range MR-SAM that the DRDO is developing with IAI. The IAF has revealed plans to raise at least two regiments that will use the MR-SAM, each with 40 launchers and support equipment. In India, the MR-SAM will progressively replace the IAF's antiquated Soviet-vintage SA-3 Pechora and SA-8 OSA-AK SAM systems. A proposed foreign-assisted upgrade of the Pechora fleet was shelved two years ago, with the IAF deciding it was more economical to pursue a limited ground-equipment modification by Bharat Electronics Ltd. The Pechora, OSA-AK and 9K38 Igla man-portable SAM systems are effectively obsolete, and the IAF admits it has had to cannibalize equipment to keep a minimum number operationally effective.
The raft of modernization activities should remedy a situation that, in June 2006, was strongly criticized by the Indian parliamentary committee on defense, which accused the defense ministry of taking a "lackadaisical approach" to existing needs and being responsible for "derailed modernization and critical voids." Shortly after the committee's stinging report was released, the government began prioritizing air defense purchases and development programs.
But these activities to not address all of the air force's concerns; radar coverage is another worry. The IAF currently has fast-track tenders out for long-range surveillance radars, high-powered radars, three-dimensional C/D band air surveillance radars, low-level transportable radars and radars for mountain surveillance in India's northern and eastern sectors.Naik notes that "10 years ago we had very little money for modernization, which led to major delays. The equipment we are contracting now will come to fruition by 2014-15. So . . . over the next three years, areas of concern will be progressively addressed."
