Need of A Submarine Launched Intercontinental Ballistic Missile for India ?
Long Range SLBM - an Ultimate Deterrent
The Indian Strategic force's as of Now do not Possess an Active SLBM.The K-15 SLBM with a range of Over 800 Km is under Production.With Induction of INS Arihant - the Lone SSBN that India Possess as of now and the K-15 Missile's,India will complete it's Nuclear Triad with Ability of Launching a Nuclear Warhead from Land,Air,Sea.But How Effective will this Triad be ? the K-15 with such a short range will it Contribute to the Triad when it come's to Maintaining deterrent against Arch-Rival China ?
Let Alone China,The K-15 Lack's the punch even when it come's to Pakistan.Thus,the development of K-4 SLBM with a range of 3,500 km and another Rumoured development of A-6 SLBM with a Range of over 6,000 Km.
India is currently Working on 2 more Arihant class SSBN's and will have an Option to build more.Nuclear Submarine's are more safer Basing option for Nuclear Missile's because of it's ability to Move and stay submerged for long duration of time when Compared to land Based Missiles.Another advantage of SLBM's is Difficulty it present to enemy surveillance, detection, and defensive systems.The soon to be tested A-5 ICBM will Cover the distant Chinese Cities If fired from North India.So it doesn't make sense to work on Further development of Long range Land based Missile's rather than Submarine Launched one's.
Along it's Advantage's there are Some Disadvantage's of SLBM.The main Advantage of such Submarine lies in it's ability to hide,But in case a "Boomer" is detected,It's effectiveness in Launching a Missile fade's away until it evades enemy Surveillance system again.Another advantage is to carry out Quieter operation while submerged under Water.
Consider a Situation where a Long range SLBM with over 10,000 Km Range deployed on a Arihant class "Boomer" submerged Somewhere Near African coast in the Indian ocean or Somewhere near South of Indonesia in the Indian ocean can Target Distant Chinese Cities like Shanghai.
To met the goal of an "Ultimate Deterrent Force", the Indian strategic force's need to Possess a "Long Range Intercontinental Submarine Launched Ballistic Missile" with 3-10 MIRV/MARV Warhead's.
