Bomb

The Hiroshima A-Bomb
The Hiroshima A-Bomb

Hydrogen bombs or thermonuclear weapons
Are also known as fusion bombs
Because they require a fusion reaction between hydrogen isotopes
That energy is produced from an A-bomb
So in essence, an H-bomb requires an A-bomb inside it to set it off

The minimum yield an H-Bomb produces is one megaton
And has a blast radius of around 30 kilometres
There's also no limit to how big an H-bomb can be
