A photon pulse fired from a type-4 phaser
A type-4 phaser is a small ship-mounted phaser of a type used on shuttlecraft.
In 2368, type-4 phasers were not normally installed on type 6 shuttlecraft but could be fitted for special purposes. The phasers were located on the forward tips of the two warp nacelles. The Magellan, a shuttle from the USS Enterprise-D, was equipped with type-4 phaser emitters in order to chart the null space in the J'naii star system with a series of photon pulses.
