A staple of Ukrainian UAV forces is the bomber drone. As the designation suggests, these drones are designed to deliver lethal payloads to the enemy and, if need be, bring needed supplies to friendly troops. Bomber drones are much larger than their smaller FPV drone counterparts and unlike FPV drones, bomber drones are meant to return to their bases once their mission is completed. There, they are readied for the next operation. Collectively, the various bomber drone types used by the Ukrainian military are nicknamed “Baba Yaga” by Russian troops who are unfortunate enough to be on the receiving end of the drone's payloads. The “Baba Yaga” bomber drone shown in the photograph is the BPAK Vampire.
The Vampire is a six-rotor hexacopter design with a weight believed to be around 40 pounds and a production cost of around $10,000USD per unit. It has a payload capacity of no more than 33 pounds. Offensive payloads can include grenades, mortar bombs (up to 120mm), and PG-7 85mm warheads (used with the RPG-7). If required, the Vampire can carry a single TM series land mine if being utilized for area denial missions. The Vampire is primarily operated nocturnally thanks to the drone being fitted with a bispectral camera (which includes thermal). Navigation is aided by a GNSS (Global Navigation Satellite System) antenna. The top speed of the Vampire is 62 miles per hour and if carrying a payload, maximum speed is 37 miles per hour. The Vampire's operating altitude is 1,640 feet and in ideal conditions, the maximum communication range between the drone and the operator's controller is 25 miles. Batteries provide the Vampire with a maximum endurance of 45 minutes when empty and if carrying a payload of 22 pounds, the endurance drops to 30 minutes. The operational range is no more than 12 miles. Typical training time for Vampire operator recruits is three hours to become competent in basic flight tasks.
A common non-combat use for the Vampire is resupplying Ukrainian troop positions where regular logistical vehicles would be hard pressed to access (or can't). Another use, though much less common, is fire-fighting using custom designed bombs filled with water. The Vampire has also been used for humanitarian operations, notably following the Russian destruction of the Kakhovka Dam, by delivering supplies to civilians cut off from ground-based rescuers.
Vampire missions can involve multiple sorties against Russian targets. Once the drone drops its payload, it returns to its base. There, the batteries are swapped out for fresh ones, the drone rearmed, and it is sent out again. Usually, reconnaissance drones identify Russian targets and then units operating the Vampire in the area are contacted with the information. Thus, with confirmed targets, only then are the bomber drones sent out. Depending on the level of activity, operators of the Vampire can fly multiple missions per night. One drone operator with the 100th. Mechanized Brigade flew his Vampire on 27 sorties in a single night.
The Vampire is not armored but has proven to be resilient against Russian small arms fire, being capable of returning to base with damage from bullet strikes. It is also resistant to Russian frequency jamming. Another protective measure is that if communication between the Vampire and its operator is broken, the drone will automatically return to its point of origin.
