Based on existing technology, the ML-77 is a rapid-fire missile launcher using seeking projectiles. Each projectile features a friend-or-foe recognition system, ensuring it will find a hostile target even if the user's aim is not completely accurate.
The weapon excels at taking out snipers and other entrenched enemies in dense urban environments. This makes it popular with mercenary groups, particularly the Blue Suns. Missile launchers have been appearing with increasing frequency in the Terminus Systems, but their point of manufacture is unknown. Legal duplication of missile launchers is difficult due to Fabrication Rights Management (FRM) technology.
