The text mentions that the breakthrough was achieved using an advanced tokamak design, which is a toroidal (doughnut-shaped) device that uses magnetic fields to confine plasma.

Fusion energy promises a clean, virtually inexhaustible energy source that could significantly address global energy needs and help combat climate change.

Deuterium and tritium are isotopes of hydrogen that are commonly used as fuel in fusion reactors due to their relatively lower ignition temperatures and higher energy yields.

Sustained net energy gain means that the fusion reaction produces more energy than is consumed to initiate and maintain it, proving the viability of fusion as an energy source.

Nuclear fusion involves the merging of light atomic nuclei, such as hydrogen isotopes, to form heavier nuclei, releasing a vast amount of energy in the process.

By building its own aircraft carrier, India reduces its dependence on foreign suppliers, saving foreign exchange and stimulating its domestic defense industry.

As an aircraft carrier, INS Vikrant significantly boosts India's power projection capabilities across the Indian Ocean Region and other strategic maritime areas.

INS Vikrant was built by Cochin Shipyard Limited (CSL), a public sector undertaking under the Ministry of Shipping.

The indigenous development and operational readiness of INS Vikrant strongly align with the 'Atmanirbhar Bharat' initiative, promoting self-reliance in defense manufacturing.

FOC means the aircraft carrier and its integrated air wing are fully prepared and capable of undertaking all assigned operational duties and missions.
