INDIA SURFACE TO SURFACE MISSILES
SENTHIL KUMAR . R
1780 ,the Battle of Guntur.
1801 , William Congreve
Senthilkumar.R
Tipu’s missile - kushoons No control surfaces
Nose cone and a cylinder
Long sword is warhead
Second Anglo-Mysore war, at the Battle of Pollilur (10 September 1780), Battle of Srirangapattana in 1792.
We supplied the missile technology to the worldSenthilkumar.R
Surface to surface Missiles
Prithvi Agni
Post Independence
Senthilkumar.R
Prithvi - I
9 m
1.1 m
Short-Range ballistic missile.
(Range of 150-330 km )
Design started in 1983 and Tested in 1988.
Four Delta-shaped wings.
Weight = 4000 Kg. payload of 500 kg to 1,000 kg
Transporter-erector-launcher (TEL)
Senthilkumar.R
Advantages
• Missile is capable of being manoeuvred up to 15 degree .
• Thrust termination Multiple payload , Multiple Range
• CEP of .01 % of its Range i.e., 10m<250m• For a nuclear, biological or chemical warhead
Prithvi - I
Disadvantages
• Missile volatile liquid fuel launch mode must be loaded immediately prior to launch.
Senthilkumar.R
Prithvi Some 100-150 Prithvi SRBMs have been produced, but how many
have been issued is unclear.
During the 1999 Kargil confrontation, it has been alleged that 4 Prithvi SS-250 were fitted with nuclear warheads to guard against any Pakistani nuclear blackmail
Behind enemy lines
Prithvi Missile Systems are gradually being inducted into the IAF.
Senthilkumar.R
Senthilkumar.R
Prithvi III Tested on On March 19, 2004 . tested on October 27, 2004 (underwater launch).
Range 250-330 Km
Payload of 500 -1000 Kg
Two stage, solid fuel, road-mobile
Sagarika and Prithvi-III are two different names for the same missile.
This medium-range missile can also be launched from a submerged submarine (Project K-15).

Senthilkumar.R
The Agni-TTB (Technology Test Bed)
Range of 1,500 km.
Payload of 1,000 kg.
Prithvi + the SLV-3 booster.
To develop re-entry and guidance technology.
Disadvantages
• Solid + Liquid propulsion configuration, unsuitable for an operational IRBM.
Senthilkumar.R
The Agni-2 IRBM Tested on April 11, 1999
Range of some 3,000 km
A 1,000 kg payload
Global Positioning System (GPS)
Cleared for production.
12 Agni-II missiles per year.
Technical Aspects
Agni-II is a 2-stage missile; both the stages are solid fuelled.
PSLV’s booster stage with an Isp of 269 (vacum) and 237(sea level).
Second stage has 1-metre diameter, about 4.8 metre length.
The stage has flex nozzles for thrust vectoring for trajectory control.
Senthilkumar.R
More advanced version of Agni-II
To adapt it to the newer and lighter nuclear payload that were proven by Pokharan-II .
Stronger 250-Marging steel, resulting in lighter booster stage case and greater fuel mass-fraction
Greater fuel mass-fraction .
Multi directional carbon re-entry nose tip and control surfaces
The Agni-2 AT
Senthilkumar.R
Agni I• Single stage version of Agni-II
• Rapidly developed after the Kargil War when the need for an intermediate range missile
• Range gap between the Agni-II and the Prithvi (700-900 km ).
•Being road /rail mobile , the misile won’t prone to pre-emptive strikes
Senthilkumar.R
• Lower cost of unit procurement, ancillary support, maintenance and deployment
•Simplicity of single stage rocket.
•More mobile.
•Stealth feature

At present, it can be assumed that India ’s land-based missile deterrent is
based around:
•Agni-II IRBM (3,500 km range, 200 kT warhead) – 18 to 36 missiles in
service.
•Agni-I MRBM (900 km range, 200 kT warhead) – 8 to 16 missiles in service.
•Prithvi-II SRBM (330 km range, 15 kT warhead) – 150 to 180 missile
produced (12 nuclear armed).
