Type of weapon



In the 2006 conflict in Lebanon, Israel used cluster munitions delivered by artillery projectiles, ground rockets, and aircraft bombs carrying five main types of submunitions: M42, M46, M77, M85 (with and without self-destruct devices), and BLU-63. These submunition types are unguided weapons that pose grave danger to civilians because of their inaccuracy, wide dispersal pattern, and high dud rates. Human Rights Watch researchers documented each of the five types lying unexploded in villages and surrounding fields in south Lebanon. Israel also widely used the M77 in Lebanon. M77 submunitions are delivered by M26 MLRS rockets. The launchers, rockets, and submunitions were produced in the United States. Each rocket contains 644 M77 submunitions, and each MLRS can fire up to 12 rockets at once.

M26 rocket by Lockheed Martin - Reserach from Medea Benjamin and Nicolas J. S. Davies in 2018 report: Lockheed Martin has also supplied Egypt with M26 MLRS rockets, fragments of which were found at the site of rocket strikes that killed civilians in Yemen. In November 2001, Lockheed Martin was awarded a $36 million contract to produce 485 extended range MLRS rockets for Egypt. Each M26 rocket contains 646 M77 submunitions, designed to explode over a large area and spray shrapnel in all directions. The yellow smaller shells inside the blue shell show a part of the M77 submunitions.
