Section 31 drone []
While on a Section 31 mission to Qo'noS, the Philippa Georgiou of the mirror universe transported into a combat situation down accompanied by a drone that immediately started firing on her targets. Its bluish-white output appeared to consist of two beams, which explosively disintegrated those it hit. (DIS: "Point of Light")
Soong's drone []
Adam Soong used these drones to generate a protective drone field around Kore Soong. (PIC: "Fly Me to the Moon") He also tried to use them to take out the Shango X-1, just in case he failed to kill Renée Picard. Cristóbal Rios gained full control of one of them and destroyed them before they reached their target. (PIC: "Farewell")
Starbase 1 drone[]
In 2259, these drones were seen flying around Starbase 1 and doing maintenance work on the USS Enterprise's hull. (SNW: "The Broken Circle")
These drones used the same model as the Section 31 drone ship, which may be a derivation of the same technology.
Starfleet target drone[]
By 2381, the phaser ranges on some Starfleet vessels, such as the USS Cerritos, featured drones that functioned as targets for phaser fire. (LD: "wej Duj")
