The SB 1000 (Spezialbombe) was a luftmine (aerial mine) used by the German Luftwaffe during World War II.

Since the SB series was not designed to pierce armor or to create fragments, the casings were very light and the ratio of charge to weight was high at 73%, while most general-purpose bombs were up to 50%.

The nose piece was threaded and was streamlined to reduce drag while the bomb was attached to the aircraft.

The tail of the SB 1000 was constructed of drawn steel and had four fins inside a circular strut.

The SB 1000 was suspended horizontally by an H-type lug or trunnions if carried by dive bombers.
