In a path breaking defence acquisition, India is going to sign a Rs 39,000 crore deal with Russia for four stealth frigates and five units of the S-400 anti-aircraft system along with agreement to launch a joint venture for the manufacture of 200 Kamov 226T light utility helicopters at a cost of about $1 billion under the "Make in India" programme.
Meeting in the background of BRICS Summit in Goa on Saturday, Prime Minister Narendra Modi and Russian President Vladimir Putin are likely to ink the deal which will provide India with the much needed fire power for the naval forces. Here is all you need to know about stealth frigates, S-400 anti-aircraft system and Kamov-226T helicopter.

A stealth ship is a ship which employs stealth technology construction techniques in an effort to ensure that it is harder to detect by one or more of radar, visual, sonar, and infrared methods.
These techniques borrow from stealth aircraft technology, although some aspects such as wake and acoustic signature reduction (Acoustic quieting) are unique to stealth ships' design. Though radar cross-section (RCS) reduction is a fairly new concept many other forms of masking a ship have existed for centuries or even millennia.
The Shivalik class or Project 17 class is a class of multi-role frigates in service with the Indian Navy. They are the first stealth warships built in India. A total of three ships were built between 2000 and 2010, and all three were in commission by 2012.

S-400 anti-aircraft system or S-400 Triumf:
The S-400 Triumf, previously known as S-300PMU-3, is an anti-aircraft weapon system developed by Russia's Almaz Central Design Bureau in the 1990s as an upgrade of the S-300 family.
It has been in service with the Russian Armed Forces since 2007. The S-400 uses three different missiles to cover its entire performance envelope. These are the extremely long range 40N6, long range 48N6 and medium range 9M96 missile.
Apart from India, China has also confirmed the purchase of six S-400 Triumfs.
Types of targets:
Strategic bombers such as the B-1, FB-111 and B-52H
Electronic warfare airplanes such as the EF-111A and EA-6
Reconnaissance airplanes such as the TR-1
Early-warning radar airplanes such as the E-3A and E-2C
Fighter airplanes such as the F-15, F-16, F-35 and F-22
Strategic cruise missiles such as the Tomahawk
Ballistic missiles (range up to 3,500 km)
Kamov Ka-226 helicopters:
The Kamov Ka-226 is a small, twin-engined Russian utility helicopter. The Ka-226 features an interchangeable mission pod, rather than a conventional cabin, allowing the use of various accommodation or equipment configurations. The Ka-226 entered service in 2002. Variants of the Ka-226 have the NATO reporting name of Hoodlum.
After the India-Russia deal, the Kamov Ka-226 helicopters will be manufactured in India as a joint venture between defence PSU Hindustan Aeronautics and Russian Rostec State Corporation.
