The type 4 phaser is a medium sized device fitted to small vehicles such as shuttlecraft. They were not normally installed on Type 6 Shuttles during the year 2368 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 Enterprise D, was equipped with type-4 phaser emitters in order to effectively chart the null space near the J'Naii homeworld.
