The Durandal rocket-boosted anti-runway munition was developed by Matra (now part of MBDA) in the 1970s, and entered service with the French Air Force in 1977. After release from the delivery aircraft, a parachute retarder system slows the Durandal until its nose has pitched down about 20° to 30°. Then the parachutes are released, and the solid-fueled rocket motor ignites to propel the Durandal to a speed of about 260 m/s. At that speed, the weapon's warhead can penetrate about 400 mm of concrete. A time-delay fuze detonates the warhead one second after impact, creating a crater of 5 m and a heavily damaged area of 7 m diameter.

The U.S. Air Force first evaluated the Durandal in 1982. It was subsequently procured for operational service as the BLU-107/B, at least partly because the USAF's own BLU-106/B BKEP (Boosted Kinetic Energy Penetrator) program suffered from delays (and was later cancelled). The BLU-107/B was used in Iraq by F-111E bombers during Operation Desert Storm in early 1991. After retirement of the F-111, the F-16 became the only USAF platform for the Durandal.
