GBU-53/B Small Diameter Bomb II (SDB II) program achieved an important milestone last week when the weapon successfully engaged and hit a moving target using its tri-modal seeker. SDB II is designed to engage moving targets in adverse weather and through battlefield obscurants. “SDB II is the first in the next generation of smart weapons that uses multi-mode seekers and fully networked enabled data links to engage moving targets in bad weather or battlefield obscurants in high threat environments,” said Harry Schulte, vice president of Air Warfare Systems for Raytheon Missile Systems.

On July 17 test, a crew of a U.S. Air Force F-15E fighter staging out of Holloman Air Force Base, N.M., released the GBU-53/B, which then acquired, tracked and guided to a moving target scoring a direct hit. during a flight test at the White Sands Missile Range, N.M. Currently in engineering and manufacturing development,

As a mission-flexible weapon SDB II is capable of defeating threats such as swarming boats, mobile air defense systems or armored targets. It’s capabilities include the ability for the weapon to be employed in three primary attack modes, each with a subset mode, for a total of six engagement modes. A dual band, two-way weapon data link for in-flight target updates and status reporting allows post-launch control of the weapon by the launching aircraft, a Joint Terminal Attack Controller (JTAC), or a third party. In addition to its adverse weather, moving-target capability, SDB II can hit targets from stand-off ranges. It has a powerful warhead capable of destroying armored targets, yet keeps collateral damage to a minimum through a small explosive footprint.

The test was part of the Navy’s Trident Warrior 2013 demonstration in July. During the demonstration, fighters simulated the launch of a JSOW C-1 while the E-2D directed the weapon toward the positively identified target. The E-2D aircraft also received status updates sent from the JSOW C-1.

“The success of the Trident Warrior 2013 demonstration proves the feasibility of providing the fleet a means of executing the complete kill chain with carrier-based assets utilizing the F/A-18E/F, JSOW C-1 and E-2D to engage maritime targets at range,” said Cmdr. Errol Campbell, the U.S. Navy’s Precision Strike Weapons program office deputy program manager for the JSOW program.

Additionally, the team was able to track and designate a target; simulate the launch of the JSOW; send, receive and acknowledge target updates; and receive bomb hit indication data from the weapon.

“This test further verifies the flexibility and seamless plug-and-play connectivity of JSOW C-1′s network-enabled capability,” said Celeste Mohr, JSOW program director for Raytheon Missile Systems. “The test demonstrates the relative ease with which the U.S. Navy can build on the ongoing integration of the JSOW C-1 on the U.S. Navy’s F/A-18 and expand the interoperability and connectivity to a fielded carrier-capable tactical airborne early warning aircraft.”

In 2009, the Navy performed a similar demonstration of connectivity and interoperability among sensor platforms, a shooting platform and the JSOW C-1 during the Joint Surface Warfare Joint Capability Technology Demonstration. This demonstration involved a P-3 Orion aircraft’s littoral surveillance radar system and an E-8C Joint Surveillance Target Attack Radar System aircraft.
