Reports indicate that INS Aridaman is larger and potentially more capable than INS Arihant, with possible upgrades in propulsion and weapon systems.

While DRDO plays a role in various defense technologies, the Arihant-class submarines are primarily developed and constructed by organizations like Bhabha Atomic Research Centre (BARC) for nuclear aspects and Larsen & Toubro (L&T) for shipbuilding.

Sea-based nuclear deterrent refers to nuclear weapons carried on submarines, which is a key component of India's nuclear triad.

Nuclear submarines capable of carrying ballistic missiles are crucial for strategic nuclear deterrence, providing a survivable second-strike capability.

INS Aridaman is the second submarine of the Arihant-class, which are India's indigenous ballistic missile submarines.

The Akash-NG is a versatile air defense system capable of intercepting a wide range of aerial threats such as fighter jets, drones, and cruise missiles.

The development and successful testing of indigenous defense systems like Akash-NG are key components of the 'Atmanirbhar Bharat' initiative, promoting self-reliance in defense.

The Akash-NG features a more compact and lighter design, along with an improved seeker for enhanced accuracy, and a dual-pulse rocket motor for better performance.

The Defence Research and Development Organisation (DRDO) is the primary agency responsible for the development of India's indigenous defense technologies, including the Akash missile system.

The Akash missile system is designed as a surface-to-air missile, intended to intercept aerial threats.
