Moody Air Force base in central Georgia said there were no reports of casualties or damage after the 11kg training non-explosive bombs fell on the afternoon of July 2 from the A-10C Thunderbolt II fighter jet.
The base said that a bird impact caused 3 bombs to be accidentally released.
The air force has not yet located the dropped bomb, but it is expected to be within a range of about 87 km south of the base, near Suwannee Springs in northern Florida.
The Air Force said that the training bombs, although bare, contained construction materials and should not be handled.
According to The Aviationist, there was no information about the status of the A-10C fighter jet involved in the incident.
Although the US Air Force has not officially confirmed the type of bomb lost in the incident, it is likely the air force's standard BDU-33 training bomb. The small training bomb is often used on A-10s and other aircraft such as the F-16.
According to the manufacturer's website's specifications and specifications, the BDU-33 is a standard 11kg training bomb used by both the US Navy and the US Air Force.
The small, blue-painted bombs are also known as the "MK-76", or " Mark-76".
The BDU-33 does not carry a destructive warhead but emits smoke when the bomb attacks a target to support the assessment of the accuracy of bombing during training.
On November 26, 2006, an A-10 of the 25th fighter squadron accidentally dropped a BDU-33 bomb at a factory in Eumseong, South Korea.
After the incident, Flight Team 51 based in Osan temporarily stopped using the BDU-33 on the A-10 aircraft.
Two similar incidents also occurred in November and December 2006 from an F-16 in Misawa, Japan.
