Full Specifications

GBU 53B StormBreaker Precision Glide Bomb

The GBU 53B StormBreaker is a network enabled precision glide bomb designed to strike moving and stationary targets in complex combat environments. Developed to replace earlier Small Diameter Bomb variants, it provides U.S. forces with an all weather capability against armored vehicles, air defense systems, and fast moving threats.

Unlike traditional laser or GPS guided bombs, the GBU 53B can engage targets through smoke, dust, rain, and darkness. Its tri mode seeker and datalink allow pilots to adjust targeting in flight, increasing flexibility in dynamic battlefield conditions. The weapon achieved initial operational capability with the U.S. Air Force in 2020 and is also fielded by the U.S. Navy.

Manufacturer

The GBU 53B is produced by Raytheon Missiles and Defense, now part of RTX, in the United States. The program originated as the Small Diameter Bomb II to expand strike options for tactical aircraft. It is integrated on platforms including the F 15E Strike Eagle, F 16 Fighting Falcon, F A 18E F Super Hornet, and the F 35 Lightning II.

The bomb combines millimeter wave radar, imaging infrared guidance, and semi active laser homing, supported by GPS and inertial navigation. This layered guidance approach improves accuracy and target discrimination.

Speed and Range

As a glide weapon, the GBU 53B does not have its own propulsion. When released from high altitude, it can reach ranges beyond 40 nautical miles, depending on launch conditions. This stand off distance allows aircraft to remain outside many short and medium range air defense envelopes.

The weapon is subsonic in flight and uses deployable wings to extend range and improve glide performance.

Cost/Price

The estimated unit cost of the GBU 53B ranges between 200,000 and 250,000 US dollars, depending on production lot size and contract structure. Pricing may vary under foreign military sales agreements and integration packages.
