Subnucleonic beam

From Memory Alpha, the free Star Trek reference

The subnucleonic beam is a Hirogen ship-mounted weapon.

A subnucleonic beam can perform rapid scans of an enemy ship and can also severely disable it. The subnucleonic beam works by disrupting a ship's propulsion systems, communications systems, weapons and its navigational sensors. Once a target ship is disabled, the Hirogen use their tractor beam technology to draw in their prey. (VOY: "Hunters")
