  Missile Systems and Their Classification

  A ballistic missile spends most of its flight with the engine off and outside the atmosphere; a cruise missile keeps its engine running the whole way and never leaves the air it needs to breathe.

  Unmanned Systems and Drones

  Not every drone can hover, and not every drone can take off vertically; the ones that can trade away exactly the range and endurance that make the ones that cannot useful.

• Science & Technology

  Radar, Surveillance and Detection

  Radar does not see an object; it measures an echo, and almost every fact worth knowing about the technology, including how stealth defeats it, follows from that one distinction.

  Energetic Materials and Explosives

  CL-20 is 15 times more powerful than the previous benchmark explosive, and the reason it matters is not the number but what it lets a warhead's designer trade away.

  Naval Systems and Maritime Technology

  INS Vikrant is not just India's first aircraft carrier, it is the proof that an entire supply chain, from steel to sonar, can be built at home rather than bought abroad.

  Strategic and Nuclear Delivery Systems

  The Prime Minister is the only person who can authorise a nuclear strike, but the body that recommends it and the body that would carry it out are deliberately two different chains of command.

  Defence Indigenisation and Procurement

  A Positive Indigenisation List does not encourage domestic manufacturing, it forbids importing the item after a fixed date, and that distinction is the whole policy.
