The classified station in Destroyer studies gravity manipulation using knowledge obtained from alien technology. Its research has already supplied the data and practical engineering for a company to develop a reactionless drive for a new generation of warships. The scientists have now turned to a deployable weapon that disrupts an opponent's reactionless propulsion and leaves the target vulnerable to missiles. They understand the basic principles of the device. Their unresolved problem is supplying enough power after the munition is disconnected from its parent ship's power plant.

Destroyer: why a gravity weapon needs its own power source
A fictional gravity weapon illustrates the gap between understanding a working principle and powering a munition independently of its launch platform.
