Milestone C

Raytheon Company and the U.S. Air Force successfully completed the Small Diameter Bomb II (SDB II) Milestone C decision briefing, paving the way for the program to enter Low Rate Initial (LRI) production. SDB II is an all-weather solution that continues to provide precision even in limited visibility scenarios.

Unlike standard bombs, SDB II employs Raytheon’s revolutionary tri-mode seeker that operates in three different modes:

  • millimeter-wave radar;
  • uncooled imaging infrared;
  • semi-active laser.

SDB II can strike targets from a range of more than 40 nautical miles/46 miles/74 km, with a dynamic warhead that can destroy both soft and hard targets. The bomb can also change targets in-flight through the use of a secure datalink.

Locked and loaded, the F-15E fighter aircraft can carry seven groups of four Small Diameter Bomb IIs, for a total of 28 weapons

«The Milestone C decision enables us to begin putting this game-changing capability into the warfighters’ hands», said Colonel Kevin Hickman, USAF SDB II program manager. «The ability to strike moving targets with extreme precision in adverse weather reduces an aircrew’s time in harm’s way and limits collateral damage in the battlespace».

The Milestone C achievement follows a successful functional configuration audit, production readiness review and system verification review. Milestone C will lead to a positive acquisition decision memorandum validating the preparedness of the company and the weapon system to continue to production.

«Achieving Milestone C marks the hard work of the U.S. government and Raytheon teams to verify that we meet or exceed the requirements necessary for a Lot 1 production decision», said Jim Sweetman, SDB II program director for Raytheon Missile Systems. «SDB II’s unique capabilities help ensure that our warfighters maintain their unfair advantage in the fight».

Small Diameter Bomb II

SDB II employs Raytheon’s unprecedented tri-mode seeker. The new seeker operates in multi-attack modes: millimeter-wave radar, uncooled imaging infrared and semi-active laser. These sensors enable the weapon to seek and destroy targets, both moving and stationary, even in adverse weather conditions from standoff ranges.

SDB II can strike targets from a range of more than 40 nautical miles/46 miles/74 km, with a dynamic warhead that can destroy both soft and armored targets, while keeping collateral damage to a minimum through a small explosive footprint. The highly accurate SDB II offers warfighters the flexibility to change targets after release through a secure datalink that passes in-flight updates to the weapon.

The Department of Defense has validated SDB II as a weapon that meets a critical warfighter need and has invested more than $700 million in the SDB II program.

SDB II can fly over 46 miles/74 km to meet its target, allowing the warfighter to maintain a secure distance from the threat

Small Diameter Bomb II can fly more than 45 miles to strike mobile targets, reducing aircrews’ time in harm’s way. The weapon’s small size allows fewer aircraft to take out the same number of targets as previous, larger weapons that required multiple jets.
