What you’ll learn

  1. A machine built for a messageExplain Tsar Bomba's Cold War purpose and design choices.A test device became a political signal because its size and yield were the message.
  2. The drop and the flashTrace the delivery and visible effects of the 1961 test.A parachute, modified bomber, airburst, fireball, and shock wave made the test survivable enough to stage.
  3. The physics of the spectacleDistinguish blast, heat, radiation, fallout, and atmospheric signals.The effects travelled through several physical pathways, while the lead tamper changed fallout.
  4. Why the machine stopped hereConnect engineering tradeoffs to the decision not to deploy Tsar Bomba normally.Extreme yield brought delivery, targeting, survivability, and strategic problems.

Questions this course answers

Why was a parachute attached?

The delay increased distance between the bomb and its aircraft.

What did the lead tamper change?

Lead reduced fast fission while preserving a huge fusion yield.

Why was it not a normal stockpile weapon?

It required a specially modified bomber and concentrated power in one difficult delivery.
