SbD

SBD is an acronym with multiple meanings across different contexts. The most widely known uses are a World War II era US Navy dive bomber, an IATA airport code, and a colloquial phrase.

Douglas SBD Dauntless: The SBD designation stands for Scout Bomber Douglas. It was a carrier-based dive bomber developed by Douglas Aircraft and used by the U.S. Navy and Marine Corps during World War II. Entering service in 1940, the Dauntless gained fame for its pivotal role in the Battle of Midway in 1942. It combined sturdy construction, armored protection, and perforated dive flaps that aided bombing accuracy. Production continued through 1944, and the type was gradually replaced by the SB2C Helldiver, though Dauntless aircraft remained in service for several years thereafter.

San Bernardino International Airport: SBD is the IATA airport code for San Bernardino International Airport in California. Located northwest of downtown San Bernardino, the facility began as Norton Air Force Base and was converted to civilian use, serving general aviation, cargo operations, and some commercial services. The airport’s code SBD is a holdover from its historical designation.

Silent but Deadly: In colloquial English, SBD is a humorous abbreviation for silent but deadly, typically used to describe flatulence that is discreet but potent. The phrase is common in popular culture and humor, but not a formal term.
