Projected stasis field
A projected stasis field, also referred to as a stasis weapon, was an experimental Klingon weapon of immense power, capable of disabling all vital systems aboard enemy vessels. It was capable of doing this to at least three ships at a time. The weapon was first field tested against the Federation in 2269, aboard the  . 

The threat of this new weapon to the Federation was analyzed by the crew of the  during an encounter in Federation space, near the Klingon-Federation border, on stardate 5392. 

During the confrontation, the Devisor successfully disabled the Enterprises higher order field and warp functions, namely the matter-antimatter generators, impulse engines, phasers and photon torpedoes, but not communications. However, upon further analysis by Science Officer Spock, it was determined that after prolonged use of the weapon, the cruiser's power cells were too quickly drained, reducing the ships battle capacity. In order to complete any prolonged assault, the cruiser was required to wait several hours for the weapon to recharge to full power. Ultimately, it was determined that the use of this weapon aboard D7s was impractical in standard combat. ()
