The heavy bomber multicopter began as an agricultural airframe with a mortar round wired to its belly. By late 2026 it is a doctrinal category — bomber, minelayer, mothership, relay, mule — flown in battalions and feared under a folklore name the Russians gave it: Baba Yaga. The airframe costs $10,000–$20,000 and delivers 15–20 kilograms of dumb ordnance with a precision a $100,000 guided shell was built to match. The war's least elegant drone is becoming its most consequential.

The war's least elegant drone is becoming its most consequential.
From Night Bomber to Flying Regiment
The Vampire hexacopter — the platform that earned the Baba Yaga name — entered service carrying TM-62 anti-tank mines and 82mm and 120mm mortar bombs, flying low and slow over Russian trenches in the dark because daylight was suicide. Russian soldiers named it for the witch of Slavic folklore because the electric rotors were a sound you heard after you were already in the target basket. That was 2023. The 2026 variant class now lifts thermobaric munitions against dugouts and buildings, carries multiple-drop release racks, and returns to reload rather than diving — attrition economics inverted in the drone's favor for once.
The missions multiplied faster than the airframes. Heavy multicopters now lay anti-tank minefields kilometers behind the front at night, converting a logistics route into a denial zone before dawn — a single TM-62 per sortie, dropped onto a road junction at 2 a.m., costs the enemy an engineering vehicle and a morning. They emplace signal repeaters and carry relay payloads over dead zones where terrain kills the control link. They fly forward ammunition, blood, and batteries — the documented use case is resupply to isolated positions under fire, where a lost $15,000 airframe replaces a lost truck, a lost crew, and a lost argument about whether the position can hold. Medevac by drone followed logically: blood plasma in, and in prototype fittings, casualty evacuation concepts out.
The Mothership Revolution
The most important 2025–2026 development is the heavy drone as FPV carrier. The physics of FPV warfare are radio physics: a 5.8 GHz control link fades past 10–15 kilometers, and low-flying quadcopters lose line of sight sooner. A heavy hexacopter loitering at altitude solves both problems — it carries one or more FPVs to within striking distance of targets 30–40 kilometers deep, releases them, and then serves as the airborne relay that keeps their video and control alive. Ukrainian units used the concept to hit logistics concentrations and air defense radars that had sat comfortably beyond the FPV front. The heavy drone stopped being a bomber and became an aircraft carrier for a swarm that costs less than the radar it kills.
Russia noticed. Its own heavy multicopter programs — commercial agricultural platforms pressed into service, then purpose-built analogs — scaled through 2025 with state procurement behind them, and Russian mothership footage followed Ukraine's by months, not years. Russian heavy hexacopters now fly the same mission set: mining, bombing, resupply, relay. The copy lag on heavy drones has collapsed from the two years it took Moscow to answer the first FPV wave to under twelve months — a compression that matters more than any single airframe.
The Cost Math Nobody Can Argue With
The spreadsheet is the doctrine. A 120mm mortar bomb dropped from a Baba Yaga with terminal correction lands within meters of the aim point; an Excalibur-class guided shell achieves similar accuracy at $100,000 or more per round. The heavy drone's payload is dumb iron delivered smart — the guidance lives in the airframe and the operator's screen, both reusable. Even after losses, the exchange rate embarrasses tube artillery on precision missions, and it embarrasses attack helicopters on survivability: no pilot, no multimillion-dollar airframe, no airfield.
The tradeoffs are real and brutal. A heavy multicopter is big, slow, and loud — a radar and acoustic signature the size of a delivery van moving at bicycle speed. Daylight operations against a prepared defense are suicide missions; small-arms fire, interceptor FPVs, and dedicated counter-UAS teams all kill heavies efficiently. Electronic warfare degrades them — a jammed heavy drone with 20 kilograms of armed ordnance overhead is a liability to everyone below it. The entire concept rests on night operations, route planning, weather discipline, and the arithmetic of mass: if the enemy must shoot down 60 percent of your sorties and the survivors still deliver, the battalion wins the month. Attrition at that rate is why the mothership role matters so much — every heavy lost carrying FPVs is one airframe trading for a radar; every heavy lost carrying mortar bombs is a wash.
Whose Drone Is It Anyway
Both militaries are now answering an institutional question with operational consequences: do heavy drones belong to the drone corps or to the artillery? Ukraine has leaned toward organic integration — heavy bomber units embedded in the expanding unmanned systems force structure, coordinated alongside FPV and reconnaissance teams as a single kill web. Russia has moved toward centralized heavy-drone formations under dedicated unmanned troops, treated closer to rocket artillery — allocated, tasked, and massed. The choice shapes everything downstream: pilot training pipelines, maintenance logistics, targeting authority, and how fast a squad leader can call in a thermobaric drop at 3 a.m. Watch the 2027 force-structure announcements. They will read like personnel paperwork and matter like doctrine.
The guided shell put precision on the price tag of a sports car; the heavy drone put it on the price tag of a used sedan, and made the car reusable.
What to Watch
- Heavy drone battalion formations. Official announcements of dedicated heavy-multicopter units — especially organic-to-brigade structures — signal the platform's graduation from improvisation to institution. - Thermobaric strike reporting. Frequency and target sets of thermobaric drops measure whether heavies are displacing artillery in the bunker-busting role. - Mothership footage. Video of FPVs releasing from carrier drones at 30+ kilometer depth marks the next range escalation cycle. - Russian analog production. State contract volumes for heavy hexacopters reveal whether Moscow is matching Ukraine's scale or accepting a capability gap. - Interceptor kill claims. Rising counter-heavy-drone kills — by FPV interceptors or air defense guns — will force the next adaptation: escorts, decoys, or altitude.
The Baba Yaga of 2023 was a scare story told in trenches; the heavy drone battalion of 2028 will be an artillery branch with propellers, and every army watching this war is already pricing its own.
