Full List Of India’s Air Defence Systems
- Ground-based air defence systems play a crucial role in a country’s defence. These are the goalkeepers of the skies. The Indian air force is right now struggling to maintain its squadron strength. In such a scenario the role of air defence systems becomes very important. In this article, we are going to look at the various types of air defence systems India operates.
- India is currently developing multi-layer air defence system. Multi-layer air defence system would ensure successful interception of incoming areal threats. India’s multi-layer air defence system would consist of four layers as mentioned below.

Components of Air Defence
- Long Range interception: Indian Ballistic Missile Defence Programme
- Intermediate Interception: S-400 Triumph (future induction)
- Short Range interception: Akash Air Defense System and Similar Systems
- Very Short-range interception: MANPADS and Anti- Aircraft Guns.
Indian Ballistic Missile Defence Programme
The
Indian Ballistic Missile Defence Program is an initiative to develop and deploy a multi-layered ballistic missile defence system to protect India from ballistic missile attacks. Introduced in light of the ballistic missile threat from Pakistan, and China, it is a double-tiered system consisting of two land and sea-based interceptor missiles, namely the Prithvi Air Defence (PAD) missile for high altitude interception, and the Advanced Air Defence (AAD) Missile for lower altitude interception. The two-tiered shield should be able to intercept any incoming missile launched from 5,000 kilometres away. The system also includes an overlapping network of early warning and tracking radars, as well as command and control posts.
Prithvi Air Defence (PAD) missile
PAD missile
The
Prithvi Air Defence (PAD) is an anti-ballistic missile developed to intercept incoming ballistic missiles outside the atmosphere (exo-atmospheric).
It has an operational range of 300 km -2000 km. It has maximum interception altitude of 80 km. it is designed to intercept incoming ballistic missiles in their intermediate cruising phase. With a maximum speed over Mach 5, PAD is fast enough to hit intermediate-range ballistic missiles.
It is a two-stage missile. The first stage is a Solid fuelled motor while the second stage is Liquid fuelled. It has manoeuvre thrusters which can generate a lateral acceleration of more than 5 gs at 50 km (31 mi) altitude. Guidance is provided by an inertial navigation system with mid-course updates from LRTR and active radar homing in the terminal phase.LRTR is the target acquisition and fire control radar for the PAD missile. It is an active phased array radar having the capability to track 200 targets at a range of 600 km
The first test was conducted in 2006 in which a PAD missile successfully intercepted a modified Prithvi-II Missile at an altitude of 50 km (31 mi). The Prithvi-II ballistic missile was modified successfully to mimic the trajectory of M-11 missiles.
Advanced Air Defence (AAD) Missile
AAD missile
Advanced Air Defence (AAD) is an anti-ballistic missile designed to intercept incoming ballistic missiles in the endo-atmosphere at an altitude of 30 km (19 mi). It is for those targets which somehow get passed through PAD. It is a secondary layer which compliments PAD.
AAD has an operational range of 150 km to 200 km. It has a maximum speed of Mach 4.5. AAD is a single-stage, solid-fuelled missile with siliconised carbon jet vanes. Guidance is similar to that of PAD with indigenous radio frequency seeker. It supports the inertial navigation system (INS), mid-course updates from ground-based radar and active radar homing in the terminal phase.
Short Range interception (less than 100 km)
Indian Army and Indian Air force operates a variety of systems in this segment. These mainly include Surface to Air Missiles (SAM) like Akash SAM, S-125 pechora, Spyder Air defense system etc
S-125 Pechora
S-125 Pechora is a surface to air missile system of Soviet origin. For a very long time, this system has been the backbone of Indian Air Force’s Air defence. This system is 60 years old as it was first inducted into service by the Soviet Union in 1961. This system has participated in almost every modern conflict. It has countless kills against various adversaries. IAF operates 25 squadrons of Pechora.

SPYDER
The
SPYDER (
Surface-to-air
PYthon and
DERby) is an Israeli short and medium-range mobile air defence system developed by Rafael Advanced Defense Systems with assistance from Israel Aerospace Industries (IAI).
The SPYDER is a low-level, quick-reaction surface-to-air missile system capable of engaging aircraft, helicopters, unmanned air vehicles, drones, and precision-guided munitions. It provides air defence for fixed assets and for point and area defence for mobile forces in combat areas.
The SPYDER launcher is designed to fire Python-5 and Derby surface-to-air missiles which share full commonality with the air-to-air missiles. There are two variants of the SPYDER: the SPYDER-SR (short range) and the SPYDER-MR (medium range). Both systems are quick reaction, all weather, network-centric, multi-launchers, and self-propelled.
A typical battery consists of one central command and control unit, six missile firing units, and a resupply vehicle. The SPYDER-SR uses the EL/M-2106 ATAR radar while the SPYDER-MR incorporates the EL/M-2084 MMR radar. The latter is the same radar used by the Iron Dome system currently in service with the Israel Defense Forces.
IAF currently operates a single squadron of SPYDER and has placed order for 4 more squadrons.

S-200
The SA-5 Gammon (Russian name S-200 Angara/Vega) is a low- to high-altitude very long-range surface-to-air missile system designed to defend large areas from bomber attack or other strategic aircraft. Initial deployment of an S-200 trials unit using the original 5V21 missile took place from 1963 to 1964 on the outskirts of Tallinn in Estonia. The first operational regiments were deployed in 1966 with 18 sites and 342 launchers in service by the end of the year.
In 1989, India purchased two S-200 Angara systems and 24 5V21 missiles from the Soviet Union. Today, the S-200 augments India’s lower altitude air defences as the country pursues more advanced ballistic missile defence capabilities, such as its Prithvi Air Defense (PAD) and Advanced Air Defense (AAD) missile interceptors. According to some unconfirmed sources, this system was retired in 2015.

KPV heavy machine gun
In the post-World War 2 period, Soviet forces inducted a new heavy machine gun known as KPV-14.5 (Krupnokaliberniy Pulemyot Vladimirova). The weapon was in development as far back as 1944 and chambered for fire the same massive 14.5×114 mm cartridge used by the Degtyaryov PTRD Anti-Tank Rifles (ATRs). Since its introduction in 1949, the KPV has gone on to see fielding as a vehicle-mounted/coaxial machine gun, dedicated Anti-Aircraft (AA) gun, and naval/watercraft machine gun.
This gun is locally manufactured by the Ordinance Factory Board Trichy and is used as dedicated AA gun. These guns are used on quadruple Gun Mounts.
