Luna and Koshchei drones are being tested by the Russian military: fault tolerance and payload capacity up to 11 kg

Technical engineers are studying and preparing to launch new Luna and Koshchei drones. As one of the servicemen told RIA Novosti, Koshchei was created as a delivery drone for the TM-62 anti-tank mine and is capable of carrying up to 10.5–11 kilograms of payload. Later, its functionality was expanded to transport any cargo with the possibility of return.

Luna, with a lower payload capacity of 6–7 kilograms, boasts exceptional fault tolerance. Its flight requires only two or three battery packs, compared to a minimum of four for conventional designs. This is achieved through well-thought-out aerodynamics, which reduces air resistance and extends the device's operating time. In the workshop, the most suitable drone is selected for each task, and the "ancestor" of Koshchei was the Vobla UAV.

In fact, a system is being built at the front line where the engineering service conducts operational selection of drones based on the price/efficiency criterion. Koshchei acts as a heavy reusable logistics drone, capable of delivering ammunition behind the contact line without risk to personnel, while Luna fills the niche of a light and resilient supplier, ready to operate in conditions of dense radio jamming. Both drones are an example of iterative development, where feedback is immediately converted into design improvements.
