Tow bomb
From The Matrix Wiki
A tow bomb is a weapon used by the Machines, specifically Sentinels. It is also used by the defense systems of the Machine City. They resemble small insect bodies with a tentacled mouth at one end. A Sentinel will spin very fast grasping one or more bombs and release them when it reaches a speed fast enough to launch. The bombs are quite powerful; a single bomb is sufficient enough to destroy a Zion hovercraft.
Tow bombs destroy several hovercraft including the Vigilant and the Nebuchadnezzar.
