India has inducted its third indigenous nuclear-powered ballistic missile submarine (SSBN), INS Aridaman, into its naval fleet.
INS Aridaman belongs to the Arihant class, marking a significant advancement in India's naval capabilities and strategic deterrence.
This induction strengthens India's nuclear triad, ensuring a credible second-strike capability from sea.
The submarine is equipped with a pressurized water reactor for propulsion and is capable of carrying submarine-launched ballistic missiles.
Nuclear submarines use a nuclear reactor for propulsion, offering virtually unlimited range and endurance underwater, unlike conventional diesel-electric submarines that need to surface or snorkel frequently. SSBNs (Ship Submersible Ballistic Nuclear) are specifically designed to carry and launch nuclear ballistic missiles, forming the sea-based leg of a nuclear deterrent. The 'Nuclear Triad' refers to a country's ability to launch nuclear weapons from three platforms: land-based ballistic missiles, strategic bombers, and submarine-launched ballistic missiles (SLBMs). This diversification ensures that even if two legs are neutralized, a retaliatory strike remains possible, providing robust deterrence.
Simple Analogy: Think of a nuclear submarine as an underwater city that can generate its own power and stay submerged for months, carrying powerful long-range missiles. A conventional submarine is more like a car that needs frequent refueling. The Nuclear Triad is like having three different escape routes from a burning building – if one or two are blocked, you still have a way out.
Primary operator and beneficiary of the nuclear submarine program, responsible for maritime defence and strategic deterrence.
Key agency involved in the design, development, and indigenous production of critical technologies for the Arihant class submarines.
The 'No First Use' policy and 'Credible Minimum Deterrence' are directly supported by the enhanced second-strike capability provided by SSBNs.
Nuclear submarines contribute to India's overall maritime security strategy, enabling extended patrols and power projection in the Indian Ocean Region and beyond.
The Arihant class program is a flagship example of India's 'Atmanirbhar Bharat' initiative in defence, reducing reliance on foreign technology.
India's nuclear program operates outside the NPT but adheres to strict non-proliferation principles, and its strategic assets are viewed in the context of global nuclear disarmament efforts.

Consider the following statements: Statement-I: India, despite having uranium deposits, depends on coal for most of its electricity production. Statement-II: Uranium, enriched to the extent of at least 60%, is required for the production of electricity. Which one of the following is correct in respect of the above statements?
Answer: Statement-I is correct but Statement-II is incorrect
In India, why are some nuclear reactors kept under "IAEA Safeguards" while others are not?
Answer: Some use imported uranium and others use domestic supplies
India is an important member of the 'International Thermonuclear Experimental Reactor'. If this experiment succeeds, what is the immediate advantage for India?
Answer: It can build fusion reactors for power generation

Ship Submersible Ballistic Nuclear; a nuclear-powered submarine capable of launching ballistic missiles.
The three-pronged capability of a nation to deliver nuclear weapons by strategic bombers, intercontinental ballistic missiles (ICBMs), and submarine-launched ballistic missiles (SLBMs).
The ability of a nuclear power to strike back with nuclear weapons even after absorbing a first nuclear attack.
A type of nuclear reactor used for propulsion in nuclear submarines, where water is kept under high pressure to prevent boiling and acts as both coolant and neutron moderator.
