Microtorpedos were 13.3cm long and were fired from a special extendable launcher tube built into the sensor pallet just beneath the cockpit. (DS9 reference: Technical Manual) In January 2377, Taran'atar placed the microtorpedoes from the USS Euphrates on the comet Nahanas, along with Prynn Tenmei's combadge. When the crew of the USS Defiant lowered their shields and attempted to beam Prynn aboard, the microtorpedoes detonated, destroying the comet. (DS9 novel: Warpath) The Delta Flyer also equiped with these torpedos.
