TL;DR Summary
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.

1. What are small yield tactical nuclear weapons?

Small yield tactical nuclear weapons are nuclear weapons with a relatively lower explosive yield compared to other nuclear weapons. They typically have a yield of less than 20 kilotons, making them less destructive and more suitable for use in military operations.

2. How do small yield tactical nuclear weapons differ from other nuclear weapons?

Small yield tactical nuclear weapons are designed for specific military purposes, such as destroying military targets or creating localized damage. They are smaller and lighter in weight, making them easier to transport and deploy in combat situations.

3. What are the potential consequences of using small yield tactical nuclear weapons?

The use of any nuclear weapon, including small yield tactical nuclear weapons, can have devastating humanitarian, environmental, and economic consequences. The radioactive fallout and long-term effects of radiation exposure can have a significant impact on both human health and the environment.

4. How are small yield tactical nuclear weapons controlled and regulated?

Small yield tactical nuclear weapons, like all nuclear weapons, are subject to strict control and regulation by international treaties and agreements. These weapons are also subject to strict safety and security measures to prevent unauthorized use or accidental detonation.

5. Are small yield tactical nuclear weapons necessary for national security?

There is ongoing debate about the necessity of small yield tactical nuclear weapons for national security. Some argue that these weapons provide a deterrent against potential threats, while others argue that their use could escalate into a larger nuclear conflict. Ultimately, the decision to possess and deploy these weapons is up to individual governments and their national security strategies.
