An airborne fire extinguishing bomb comprises a window breaking cone, a main bomb body and a miniature rocket engine, wherein the window breaking cone is installed on the end face of the front end ofthe main bomb body through a bomb body head cone; the head of a window breaking impacting pin of the window breaking cone is blunt, and antiskid lines are machined on the head of the window breaking impacting pin, so that skidding between the window breaking impacting pin and glass is prevented. The miniature rocket engine is installed on the end face of the other end of the main bomb body. A central grain and an annular cartridge bag are disposed in a filling cabin of the main bomb body. The annular cartridge bag is used for breaking and opening the fire extinguishing agent filling cabin, a supporting sleeve and a shell. The central grain is detonated in a fire extinguishing agent so as to release the fire extinguishing agent. The airborne fire extinguishing bomb can be mounted and launched on an aerial platform, is not limited by the fire extinguishing height, achieves light weight, large fire extinguishing agent loading weight, a wide action range, a high flight speed and a small descent rate, and is quick and easy to use.
