- "You hit one proton bomb, and you'll touch off the whole magazine."
- ―Sabine Wren, to Garazeb Orrelios
Proton bombs were powerful explosive weapons carried by bomber craft such as BTL-A4 Y-wing starfighters and TIE/sa bombers. Some of the bombs themselves were spherical in appearance, while other cylindrical ones could also be used as high yield explosives capable of producing great damage to heavily armored vehicles such as an AT-AT.
