It had been in service with the Swedish JAS 39 Gripen aircraft, but was withdrawn after the government of Sweden decided to sign the Convention on Cluster Munitions banning the use of BK90.
In conjunction with the LITENING targeting pod, the weapon is currently operational with the Hellenic Air Force carried both by the F-4E PI-2000 AUP and the now retired A-7E Corsair II.
"Cluster bombs" are notorious for leaving active un-exploded ordnance (UXO) which failed to detonate upon impact, and for that reason all weapons using sub-munitions for a long time were rejected by the Försvarets Materielverk Defence Materiel Administration deeming it an unacceptable risk.
There was a significant need for a weapon that have a smaller risk area than a bomb (sometimes called a mine-bomb in Swedish literature), and have the capacity to destroy a large number of targets attacking in mass.
A significant amount of resources was devoted to developing this system, and to make sure that no matter what happened, an UXO would never become active and pose a danger to the civilian populace.
