butterfly bomb
Very LowTechnical / Historical / Military
Definition
Meaning
A small, anti-personnel cluster bomb designed to scatter submunitions that resemble butterfly wings.
A specific type of air-dropped munition, historically used in WWII, which disperses numerous small bomblets that are often brightly colored and attractive but highly dangerous, especially to children.
Linguistics
Semantic Notes
The term is highly specific and almost exclusively refers to the German SD-2 'Splitterbombe' used in World War II. The 'butterfly' name comes from the visual appearance of the deployed bomblets, not their function.

Common Mistakes

FAQ
Frequently Asked Questions
No. A butterfly bomb is an air-dropped cluster submunition. A butterfly mine (like the PFM-1) is a small, scatterable land mine, often deployed from aircraft or artillery. Both are anti-personnel but are different weapons.
It is named for the visual appearance of its cylindrical body and two spring-loaded, wing-like metal stabilizers that pop out after being dropped, making it look like a butterfly or a child's toy.
Yes. Unexploded butterfly bombs (and other WWII-era ordnance) are still found in Europe and North Africa. They remain highly unstable and dangerous, often requiring controlled detonation by specialists.
Extremely rarely and with caution. Its meaning is so specific and technical that any metaphorical use (e.g., calling a charming but problematic person a 'butterfly bomb') would likely confuse listeners and is not an established idiom.
