_Slave I'_s minelayer deploying a seismic charge A mine launcher, also known as a minelayer, represented a weapon system installed on a vehicle for the purpose of deploying mines. When these systems were integrated into spaceships (frequently specialized vessels referred to as minelayers), they were utilized to release space mines.
The minelayer served the function of launching or releasing a mine, which could subsequently be activated through a timer or by remote activation. The mine would then automatically explode when specific pre-set conditions were met, such as the approach of an enemy vessel, while the minelaying vessel remained at a secure range.
