Laser pulse system
A laser pulse system was a modification that enabled a laser beam to be fired through a starship's weapons array. This modification to a starship's weapons system allowed for simulated phaser and photon torpedo operation and performance, but with no potential for actual damage. The system was used to record hits in Starfleet battle simulations without risking damage to the ships involved. 

In 2365, the 's primary weapons were disconnected and hooked up to a laser pulse system in order to participate in Operation Lovely Angel, a training exercise with the , which was similarly outfitted. Unfortunately, during the exercise the Enterprise was attacked by the Ferengi vessel Kreechta, fusing the connections to the laser pulse system. The laser system could not be disengaged, meaning that the Enterprise could not return fire with normal weapons. ()
