SUMMARY

Tactical nuclear weapons achieve low yields, such as 10 tons of TNT, through advanced design techniques that optimize the use of fissile materials. Traditional uranium fission bombs, which can produce around 10,000 tons of TNT, cannot be scaled down to such low yields due to the critical mass requirements of U-235. Instead, modern tactical devices utilize deuterium-tritium (D+T) boosting to enhance energy release beyond conventional limits. The specifics of nuclear explosive design remain classified and are not publicly discussed.

PREREQUISITES
  • Understanding of nuclear fission principles
  • Knowledge of critical mass concepts in nuclear physics
  • Familiarity with deuterium and tritium as nuclear fuels
  • Awareness of the historical context of nuclear weapon development
NEXT STEPS
  • Research the principles of nuclear fission and fusion
  • Study the effects of critical mass on nuclear weapon design
  • Explore the role of D+T boosting in modern nuclear weapons
  • Investigate the history and evolution of tactical nuclear weapons
USEFUL FOR

Defense analysts, military strategists, nuclear physicists, and anyone interested in the technical aspects of nuclear weaponry.

TL;DR
How are the small yields of tactical nuclear weapons achieved?
Uranium fission bombs have explosive power ofabout 10 000 tons of TNT. I understand that you can't make a uranium bomb with explosive power of 5 megatons of TNT brcause of the critical mass of U-235. Similarly you can't make an atomic fission weapon with explosive power of 10 tons of TNT because the mass of U-235 would be below the critical mass. So how do tactical nuclear weapons achieve such low yields?

It would be a waste of material for 10 ton TNT U-based nuclear device. Older U devices have been decommissioned in favor more modern devices. To obtain energy releases in excess of 10 kT TNT-eq, devices are boosted with D+T. Design of nuclear explosives are not for public discussion.
