The SB 2500 (Spezialbombe) was a luftmine or aerial mine in English used by the Luftwaffe during World War II.

Since the SB series was not designed to pierce armor or to create fragments, the casing of the series was very light, and the ratio of charge to weight was high at 65%, while the majority of general-purpose bombs were up to 50%.

The SB 2500 was filled through the nose and the tail cone was hollow to increase the bombs charge to weight ratio.

A central exploder tube also ran through the center of the bomb from the forward fuze pocket to the tail.

Due to its thin case and powerful explosives, the SB 2500 was vulnerable to enemy gunfire.
