Ukraine — 2022 – present: The factory comes back

Russia – Ukraine · 50 m contour · 250 m index

A thousand kilometres of front, barely moved since 2022
Russia fires 10,000 shells a day to Ukraine’s 2,000
Depots pushed 100 km back; drone workshops a day from the trench

A thousand kilometres of front, and it has barely moved since 2022. Russia fires about 10,000 shells a day to Ukraine’s 2,000 [1], from plants making 250,000 a month [2]. Ukraine answered from workshops near the fight: 50,000 FPV drones a month by early 2024 [3], 2.2 million drones for the year [4]. A Western shell takes months to arrive. A drone from Dnipro takes a day.

Factory to front: ≈ 200 km — Ukrainian workshops; Western shells 8,000 km
Order to delivery: Days vs. months — domestic drones vs. allied shells
Main transport: Rail, truck & drone — the last kilometre by air
Shells fired: ≈ 10,000 vs. 2,000 / day — Russia vs. Ukraine, 2024 estimate
Depot to front: ≈ 100 km — depots pushed back out of rocket range, 2022; workshops a day from the trench

How far the depot sat from the fight

Distance from the last stocked depot to the fighting, one point per war. For 130 years it stayed within a day’s haul. Precision rockets have now pushed it back to 100 km.

Napoleonic 1815: 12 km
American Civil War 1864: 13 km
First World War 1916: 15 km
Second World War 1944: 15 km
Korean War 1950: 90 km
Vietnam War 1968: 10 km
Desert Shield / Desert Storm 1991: 10 km
Operation Iraqi Freedom 2003: 70 km
Global War on Terror 2009: 20 km
Russia – Ukraine 2022: 100 km

Production, not printing

For two centuries the factory moved away from the fight, until a war could wait months for it. The depot moved too. It sat 12 km behind the line at Waterloo and 13 km at Petersburg. In Ukraine it has been pushed 100 km back, because anything big enough to be a depot is now a target.

GRAMDYNE builds for that gap. We do not 3D print parts at the front. A printer turns out a few frames a day. Our process is different: one machine makes about 300 times as many drone frames a day as a printer does, and it can sit anywhere a truck can park. That is production, not prototyping.

Front lines are simplified from published campaign maps and are approximate. Logistics figures are cited in each section.
