In contrast, the GBU-53/B Small Diameter Bomb II integrates multiple terminal guidance systems, including active radar, semi-active laser homing, and a thermal imaging seeker. Satellite and inertial navigation are used only during midcourse flight. Thus, even if the satellite connection is jammed, the StormBreaker can still reach the target area and independently acquire the target, without needing precise coordinates.
The shift to considering a jet engine over a rocket booster by Raytheon is likely influenced by lessons learned in Ukraine, where modern electronic warfare and air defense systems present significant challenges. In the past, Ukraine received Raytheon’s RIM-7 SEASPARROW missiles, a direct development of the AIM-7E Sparrow air-to-air missile system. These advanced missiles, launched from Soviet-era 9K37 BUK (NATO designation SA-11) systems, significantly enhanced Ukraine’s defense capabilities.
