India has elevated its nuclear deterrence capabilities with the successful test of the K-4 submarine-launched ballistic missile (SLBM). This significant event occurred from INS Arighat, India’s second nuclear-powered ballistic missile submarine, with the test conducted in the Bay of Bengal.
The K-4 missile demonstrates a formidable range of 3,500 kilometers and is engineered to carry a nuclear warhead, marking a substantial strengthening of India’s naval nuclear power.
Key Features of the K-4 Missile
- The K-4 is a solid-fueled, two-stage intermediate-range ballistic missile.
- It is capable of delivering a nuclear payload of up to 2 tons.
- The missile employs cold-launch technology, meaning it exits the water before its engine ignites. This method enhances the safety of the submarine.
Strategic Impact of the K-4 Test
This successful test significantly fortifies India’s nuclear triad, providing robust capabilities for attacks from land, air, and sea. Previously, INS Arihant was equipped only with the K-15 missile, which had a limited range of 750 kilometers. With the K-4’s extended range of 3,500 kilometers, Indian submarines can now target entire regions from secure operational areas such as the Bay of Bengal or the Arabian Sea, eliminating the necessity to approach enemy territories closely.
Furthermore, the K-4 missile substantially enhances India’s second-strike capacity under its ‘no first use’ policy. Submarines, by their nature, are difficult to track underwater, thereby complicating enemy efforts to detect and neutralize them.
Comparison with Pakistan’s Missile Capabilities
In comparison, Pakistan’s longest-range missile is the Shaheen-3, which possesses a range of 2,750 kilometers. The Shaheen-3 is a land-based missile designed to cover all of India, yet its range is 750 kilometers less than that of the K-4. Pakistan currently does not possess sea-launched ballistic missiles. However, Pakistan is actively developing its Babar-3 and Ababeel missiles, with projected ranges of 450-700 kilometers and 2,200 kilometers, respectively.
The K-4 missile not only provides India with a considerable technical and strategic advantage but also significantly enhances the nation’s maritime security. Future plans include the development of K-5 and K-6 missiles, expected to have even greater ranges of 5,000 to 6,000 kilometers.
