Heavy-lift drone resupply against a helicopter or a road convoy: getting 70 kg to a position without a crew on the route.
Forward resupply is usually a helicopter sortie or a vehicle convoy, and both put people and a high-value platform on a known, targetable path. A heavy-lift drone changes what is exposed to move the same load, at the cost of range and speed a buyer has to weigh honestly.
This is a specified aircraft, not a concept. A quadcopter multirotor with a 180 kg maximum take-off weight carries up to 70 kg, flies at 3,000 m above sea level and 300 m operational altitude above ground, holds 20 minutes of endurance at sea level with a full payload, communicates to up to 10 km and cruises to 40 km/h.

|---|---|---|---|
| Load carried1The drone is not competing on tonnage. It competes on moving a specific forward load without exposing a crew or a vehicle to the route. | Up to 70 kg on a 180 kg airframe | Far larger loads in one lift, which is the helicopter's advantage | Very large loads, bounded by vehicle capacity and the road |
| People on the route1 | None; the aircraft flies the load, the crew stays at the launch point | Aircrew on every sortie, exposed for the duration of the flight | Drivers and escort on the road for the length of the move |
| Path exposure1 | Flies a direct air route rather than a fixed road, so the path is not a known choke point | Air route, but a high-value crewed platform an adversary prioritises | A road that can be mined, ambushed or cut, and is often the only route |
| Reach1 | Communication range up to 10 km | Long range and high speed, well beyond a short-range multirotor | As far as the road runs, given time and a secure route |
| Speed1 | Cruise up to 40 km/h | Much faster, measured in hundreds of km/h | Road speed, slowed by terrain, security and the load |
| Endurance with full load1 | 20 minutes at sea level with a full payload | Long sortie endurance, refuelled and re-crewed | Not endurance-limited, but time-limited by the route |
| Origin and support1 | Independent, non-aligned origin, supplied and supported by one accountable team, sustained in region | Depends on the aircraft type and its origin; a major fleet dependency | Vehicle and route are organic, but the load still has to reach the road head |

What the table means
The drone is not trying to be a helicopter.
A helicopter lifts far more, flies far faster and reaches far further than a 70 kg multirotor, and any honest comparison says so up front. What the drone changes is the exposure. A crewed sortie risks aircrew and an expensive airframe on every run; a convoy risks drivers and escort on a fixed, targetable road. The drone moves a specific forward load with nobody on the route and no vehicle on the road, and that is the trade it is built to make.
The load and the reach set where the drone fits.
Seventy kilos to up to 10 km at up to 40 km/h is a forward-resupply leg, not a theatre logistics run. It fits the last stretch to a position a vehicle cannot reach safely, or should not: the leg that otherwise waits for a road to be cleared or a helicopter to be spared. For anything larger or further, the helicopter or the convoy is still the tool. Work out the specific loads and distances first, because that is what decides which method wins.
The endurance figure is stated honestly, and it constrains the mission.
Twenty minutes at sea level with a full payload is a short window, and it should be planned as one. It is enough for a short forward leg and a return, not a long haul, and a full load and altitude both cut into it. The value is not in the flight time; it is in keeping a crew off a dangerous route for that short window. Plan the sortie against the real endurance rather than the range figure alone.
Questions buyers ask
Can a drone replace a helicopter for resupply?
Not for volume or distance. A helicopter lifts far more, flies faster and reaches much further than a 70 kg multirotor that cruises to 40 km/h with 20 minutes of full-payload endurance. What the drone replaces is the exposure of a crewed sortie for a specific forward load: it moves that load with nobody on the route. Use it for the leg where risking a crew or an aircraft is the problem, not for the theatre-scale lift.
Why use a drone instead of a road convoy for forward resupply?
A convoy runs a fixed road that can be mined, ambushed or cut, with drivers and escort exposed the whole way. A heavy-lift drone flies the load direct, so no people and no vehicle are on that road for the move. It carries up to 70 kg to up to 10 km, so it suits the forward leg to a position the convoy cannot reach safely rather than the bulk resupply the convoy still does best.
How much can this heavy-lift drone carry?
Up to 70 kg on a 180 kg maximum take-off weight airframe. That is the heavy end of a forward-resupply line rather than a bulk lifter, sized for the load a small position actually needs rather than the tonnage a helicopter moves.
How far and how fast does the heavy-lift drone go?
It communicates to up to 10 km and cruises to 40 km/h, with 20 minutes of endurance at sea level carrying a full payload. Those figures make it a short forward-leg tool, so plan the sortie against the endurance and range together rather than the range alone.
Does this drone come with the export strings of a foreign helicopter fleet?
No. It comes from an independent, non-aligned supplier with one accountable team and in-region sustainment, rather than the foreign-origin supply relationship a major crewed platform carries. For a buyer weighing a resupply drone against expanding a foreign-origin helicopter fleet, the supply relationship is part of the comparison.
