Propulsion System
Engine Name
1 x CLWR-B1 pressurized water reactor
Engine Type
The reactor consists of 13 fuel assemblies each having 348 fuel pins. The PWR consists of a huge pressure hull, a tank containing water and a reactor. It also consists of a pressure vessel built from unique steel, a control room as well as an auxiliary control room.
The propulsion plant housing the reactor is 42m long and 8m in diameter. The complete propulsion plant along with the primary, secondary, electrical and propulsion systems occupy half of the submarine. To reduce the weight of the plant, light water and enriched uranium was used as opposed to non-enriched uranium used in land-based reactors.

Main Weapon System
Note
Arihant is capable of carrying all types of missiles and has underwater ballistic missile launch capability. It can carry 12 x K-15 SLBMs that can be launched even under ice caps.
The K-15 missiles are 10.4m long and have a diameter of 1m. The 6.3t missiles can carry a 5t nuclear warhead targeted 750km away. The K-15 missiles, however, will be replaced later by the 3,500km range K-X missiles.
Apart from the K-15s, the submarine will carry a range of anti-ship and land-attack cruise missiles and torpedoes.
Sonar Systems
Note
Arihant is fitted with a combination of two sonar systems – Ushus and Panchendriya. Ushus is state-of-the-art sonar meant for Kilo Class submarines. Panchendriya is a unified submarine sonar and tactical control system, which includes all types of sonar (passive, surveillance, ranging, intercept and active). It also features an underwater communications system.
