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 Template:ShipClass IKS Gr'oth.
During the confrontation, the Gr'oth successfully disabled the Enterprise, but 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, proving to equally crippling to itself. In order to complete any prolonged assault, the cruiser was required to wait several hours for the weapon to recharge to full power.
