Six missions that need more than one machine
Each is set out as a concept of operations — the problem, the sequence, the force mix, and what degrades it. No case studies, because we have not earned any yet.
A target of interest moves 40 km across broken terrain over nine hours. A single aircraft loses it at the edge of its endurance, at the edge of its sensor cone, or the moment it turns to refuel. The operator gets a track, then a gap, then a new track he cannot prove is the same object.
Continuous custody across four airframes
Onboard detection classifies a moving vehicle and opens a track file with a unique identity.
The operator marks the track as a target of interest. Nothing downstream requires further input.
The system computes A-01's remaining endurance and launches A-02 to arrive before bingo, not after.
Track state, identity and sensor lock pass between aircraft while both hold the target in view.
A relay orbits high so the mesh reaches past the ridgeline as the target moves out of direct sight.
The same transfer runs at each endurance boundary. Operator workload does not grow with duration.
6 assets, one operator
What degrades this, and what the system does about it
Stated plainly because an evaluator will find these anyway. Mitigations are design decisions, not guarantees.
Position solutions degrade or drop, and a target's geolocation becomes unreliable at the moment it matters most.
Every tracking aircraft in this mix carries GNSS-denied navigation as standard. Track geometry is held by visual-inertial odometry and terrain matching, and absolute coordinates carry a stated confidence rather than being silently wrong.
Around dawn and dusk, ground and vehicle temperatures converge and EO/IR detection rates fall sharply.
The system flags the crossover window rather than reporting a clean track. Where a Tier 4 night-capable aircraft is in the mix, custody is preferentially handed to it through the window.
Ridgelines cut line of sight between aircraft, and a transfer attempted during an outage loses track identity.
The relay is positioned from terrain rather than a fixed pattern, and transfers are scheduled only while both aircraft hold a link. A transfer is deferred rather than attempted blind.
Above roughly 12,000 ft, thinner air costs hover efficiency and the endurance the handoff schedule assumes no longer holds.
Endurance is computed against density altitude, not sea level. The relief aircraft launches earlier as altitude rises, so the overlap window is preserved.
A target that stops under cover, or splits into two vehicles, breaks the single-track assumption entirely.
The track file forks and the operator is asked which identity to hold. This is a deliberate human decision point, not an automated guess.
