AGM-154 JSOW series
A series of American-designed,1,000-pound-class air-delivered bombs produced by Raytheon, with a maximum effective range of more than 100 km. The JSOW, or ‘Joint Standoff Weapon’, uses GPS and inertial navigation for guidance. The AGM-154C is additionally fitted with a terminal infrared seeker. The ‘A’ variant of the munition carriesBLU-97 submunitions, whilst the ‘C’ variant is fitted with a multi-stage BROACH (‘Bomb Royal Ordnance Augmented Charge’) warhead—comprising a WDU-44 shaped charge (penetrating) warhead and WDU-45 follow-through warhead. An updated ‘A-1’ variant was introduced for foreign sales to avoid the use of submunition; it contains a BLU-111 500-pound-class bomb warhead instead. Since its introduction in 1999, the munition has seen use in a number of conflicts, including the 2001 Afghan War, 2003 Iraq War, and the ongoing air campaign against Yemen’s Houthis.

US munitions used in Yemen 2025
Verified images of U.S. munitions during the Trump administration’s bombing campaign against the Iranian-backed Houthi militant and political group.
Analyst Note:
This image shows an American F/A-18 fighter aircraft armed with two AGM-154 Joint Standoff Weapon (JSOW) air-delivered bombs taking off to conduct strikes against Houthi forces in Yemen. The F/A-18 likely has two more AGM-154-series munitions carried on the opposite side of the aircraft, for a total of four bombs. The JSOW has multiple variants which are fitted with different warheads, including a submunition payload (AGM-154A and AGM-154B models), BLU-111 500-pound bomb (AGM-154A-1), and a Bomb Royal Ordnance Augmented Charge (BROACH) multi-stage penetrator warhead (AGM-154C or AGM-154C-1). All variants are externally identical without markings, with the exception that the AGM-154C and C-1 have a small reflective window on the bottom of the nose for the terminal infrared (IR) seeker. The munitions in the image are most likely AGM-154A-1 or AGM-154C-series bombs, due to the lack of reported submunitions following the strikes. (ARES)
Analyst Note:
This image shows an unexploded WDU-45/B, the second stage or penetrator warhead (also called a ‘follow-through’ warhead), of the Bomb Royal Ordnance Augmented Charge (BROACH) multi-stage warhead system used in the AGM-154C variant of the Joint Standoff Weapon (JSOW) air-delivered bomb. The first stage is a shaped-charge warhead designed help the second stage penetrate hardened targets before detonating. The Shadow/SCALP-EG missile also uses a multi-stage BROACH system, but with larger warheads. (ARES)
