A comprehensive look at INS Arighat, India's nuclear-powered submarine, its strategic importance, and how SSB aspirants can leverage knowledge about it.
"To be prepared for war is one of the most effective means of preserving peace."

Introduction

India’s maritime power is a cornerstone of its national security, with the Indian Navy playing a pivotal role in protecting the country’s interests in the vast expanse of the Indian Ocean. Among its most powerful assets is INS Arighat, an indigenously-built, nuclear-powered ballistic missile submarine (SSBN). As the second submarine in the Arihant-class, it signifies India’s growing prowess in underwater warfare, deterrence, and self-reliance under the Make in India initiative.

This blog will delve into the key features, strategic significance, and relevance of INS Arighat, especially for candidates appearing for the Services Selection Board (SSB).

The Emergence of INS Arighat

Commissioned in late 2022, INS Arighat is India’s second Arihant-class submarine. It builds upon the success of INS Arihant, India’s first SSBN, and is a testament to the country’s ambition to establish a credible nuclear triad—the ability to launch nuclear strikes from land, air, and sea.

Key Features of INS Arighat:

  1. Nuclear Propulsion System:
    INS Arighat is powered by an 83 MW pressurized water reactor, providing stealth, extended underwater endurance, and operational flexibility.
  2. Ballistic Missile Capability:
    The submarine is equipped with K-15 Sagarika missiles (750 km range) and can potentially carry K-4 missiles (3,500 km range). This capability ensures strategic deterrence against adversaries.
  3. Stealth Technology:
    Advanced acoustic silencers, hydroplanes, and low-noise propellers enhance its stealth, making it difficult to detect even for sophisticated sonar systems.
  4. Operational Range and Endurance:
    Thanks to its nuclear reactor, INS Arighat can stay submerged for extended periods, offering unparalleled endurance and operational depth.
  5. Crew Accommodation:
    The submarine is designed to host a crew of approximately 100 personnel, emphasizing crew comfort and efficiency.

Strategic Importance of INS Arighat

Strengthening India’s Nuclear Deterrence

As an SSBN, INS Arighat provides India with a second-strike capability, a critical element in nuclear deterrence. Unlike surface ships or land-based missile systems, a submarine’s stealth and mobility ensure survivability in the event of a nuclear attack.

Maritime Security in the Indian Ocean Region (IOR)

India’s geostrategic location in the IOR, a crucial trade route, necessitates a powerful navy. With INS Arighat, India can secure sea lanes, deter adversaries, and project power across the region.

Boosting Indigenous Defense Manufacturing

INS Arighat underscores India’s strides in indigenous defense manufacturing, reducing dependency on foreign technology and enhancing self-reliance.

Countering Regional Threats

In an era of rising tensions in the Indo-Pacific, INS Arighat enhances India’s ability to counter threats from adversarial navies, including China’s expanding submarine fleet.

Why SSB Candidates Should Know About INS Arighat

In the SSB interview process, awareness about contemporary defense technology and strategic assets demonstrates your interest in national security and your potential as a future officer. Understanding the significance of INS Arighat is essential for naval aspirants and those aiming to join other services.

Topics Related to INS Arighat That May Arise in SSB:

  1. Questions in the Interview:
    • "How does INS Arighat contribute to India’s nuclear triad?"
    • "Discuss the strategic importance of SSBNs in modern warfare."
  2. Group Discussions (GDs):
    • “Role of indigenous defense technology in strengthening India’s military.”
    • “Impact of strategic submarines on regional stability.”
  3. Lecturette Topics:
    • “India’s nuclear triad and its importance.”
    • “Challenges in developing indigenous defense platforms.”
  4. Situation Reaction Test (SRT):
    • A scenario involving maritime threats or the importance of deterrence might require you to reference platforms like INS Arighat.

Example Story: How INS Arighat Helped a Candidate Ace Their SSB

Let’s explore a fictional but plausible story of Amit, an SSB aspirant aiming to join the Indian Navy. During his Personal Interview, the Interviewing Officer (IO) asked him:

"Can you explain India’s nuclear triad and how INS Arighat fits into it?"

Amit, having read extensively about INS Arighat, responded confidently:

"India’s nuclear triad ensures second-strike capability via land-based missiles, aerial platforms like bombers, and sea-based assets. INS Arighat, being a nuclear-powered ballistic missile submarine, is a cornerstone of the maritime leg of this triad. Its stealth and endurance make it a vital deterrent, especially given India’s no-first-use policy."

The IO, impressed, further quizzed Amit on the submarine’s technical features and its importance in countering regional threats. Amit’s in-depth knowledge not only showcased his awareness but also his analytical thinking. He later credited this knowledge as one of the reasons he got recommended.

Challenges in Developing Submarines Like INS Arighat

  1. Technological Complexity:
    Building a nuclear-powered submarine involves mastering complex technologies, including miniaturized reactors and stealth designs.
  2. High Costs:
    The development and maintenance of SSBNs like INS Arighat require substantial investment.
  3. Secrecy and Security:
    Ensuring confidentiality during development is critical to prevent technology leaks or espionage.
  4. Operational Training:
    Training crew members to operate nuclear submarines is a long and rigorous process.

The Future of India’s SSBN Program

INS Arighat is just the beginning of a robust SSBN program. Plans for more advanced SSBNs, equipped with longer-range ballistic missiles, are already underway. These developments will solidify India’s position as a major maritime power and enhance its ability to maintain peace and stability in the region.

Conclusion

INS Arighat is more than just a submarine; it is a symbol of India’s ambition, self-reliance, and strategic foresight. For SSB aspirants, understanding its significance reflects not only awareness of national security but also the qualities of a future officer—keen observation, analytical skills, and a sense of responsibility.

Whether you are preparing for an SSB interview, a group discussion, or simply wish to broaden your understanding of India’s defense capabilities, INS Arighat serves as a perfect example of how technology and strategy converge to safeguard the nation.
