GBU-53/B StormBreaker Smart Glide Bomb

The GBU-53/B StormBreaker is a next-generation precision-guided glide bomb designed to strike moving and stationary targets in all weather conditions. Developed to meet evolving battlefield demands, it provides U.S. forces with a highly adaptable, network-enabled weapon capable of engaging targets in complex environments, including low visibility and contested airspace. Its compact size allows aircraft to carry more munitions per sortie, increasing overall combat effectiveness.

Manufacturer

The StormBreaker is produced by Raytheon Technologies, a leading U.S. defense firm specializing in advanced missile systems and precision weapons. The program originated under the Small Diameter Bomb Increment II initiative, aimed at enhancing strike flexibility against dynamic targets.

Speed and Range

The GBU-53/B is an unpowered glide bomb, released from aircraft at altitude and guided to its target. It can achieve a stand-off range of over 40 nautical miles, depending on release conditions such as altitude and speed. While it does not have its own propulsion system, its aerodynamic design allows it to maintain high subsonic glide speeds and extended reach, keeping launch platforms outside threat zones.

Cost / Price

GBU-53/B StormBreaker Smart Glide Bomb Price

The estimated unit cost of the StormBreaker is approximately $200,000 to $250,000 per weapon, depending on production lot and contract terms. This reflects its advanced tri-mode seeker and network-enabled capabilities, making it more expensive than earlier small diameter bombs but significantly more versatile.
