The Pericles was said to be a reworking of the heavy-duty Hercules-class shuttlecraft. Its armament consisted of three phaser emitters and a photon mortar cannon capable of launching photon grenades. Unlike the Wasp-variant "Killer Bees", they were capable of atmospheric flight and planetary landing.
Two of these craft were allotted to the Enterprise-B in December 2295. Captain Pavel Chekov named them the Yerogova and the Litvyak, after female fighter pilots who fought for the Soviet Union during World War II. (Orion Press: "Clash")
