The Fuel Convoy Problem
Moving fuel to where it is consumed concentrates risk onto a predictable, repeated, exposed movement that an adversary can target.
A predictable, repeated movement
A fuel convoy is a repeating pattern: known origins, known destinations, roads that cannot change much, and a schedule driven by consumption rate. Predictability is the core weakness. The more fuel a site burns, the more often the convoy must run, and the more exposure accumulates over time.
The relationship is direct: consumption rate sets resupply frequency, and resupply frequency sets exposure. Reducing on-site fuel demand, or extending the interval between deliveries, reduces the number of exposed movements. Fusion fuels matter here because of their energy density, which in principle lengthens the interval between resupplies dramatically.
Why demand reduction beats hardening
Convoys can be hardened with armor, escorts, and route variation, but hardening does not remove the movement; it only makes each movement more expensive in effort and personnel. Removing or greatly reducing the movement is categorically stronger than protecting it. That is the logistics argument for on-site, long-fuel-interval generation.
- Convoys are predictable in origin, route, and cadence
- Higher consumption means more frequent, more exposed movements
- Hardening protects the movement; demand reduction removes it
- Energy-dense fuel lengthens the resupply interval
Route variation, timing changes, and decoys can reduce predictability, but they cannot make a repeating requirement disappear; the destination and the consumption rate remain fixed. That is why analysts treat convoy exposure as a function of demand rather than of tactics. The tactics manage residual risk after the demand is set; only lowering the demand changes the size of the problem the tactics must cover.
This page describes a logistics principle. The fusion machines that could act on it are still design-and-simulation studies subject to the honest gates documented elsewhere in this section.
