Scenario 1 · Yorkshire Flood Response
MET OFFICE + EA + COASTGUARDRESILIENCE FORUM
Trigger: Met Office forecasts 200mm of rain in 24h across North Yorkshire. Environment Agency river-level sensors show River Ouse rising 0.3m above seasonal normal at Skelton. DEFONEOS must correlate forecast, sensor, demographic, and infrastructure data; classify the threat; and pre-position response assets.

Scenario 2 · Dark Vessel Detection — North Sea
AIS + SATELLITE + RFMARITIME OPS CENTRE
Trigger: AISstream shows a 3-hour gap in tracking for a 290m tanker off the coast of Northumberland. DEFONEOS must determine if this is an AIS equipment fault, a sanctioned vessel attempting to spoof, or a "dark" vessel engaged in illicit activity (sanctions evasion, illegal fishing, smuggling).

T+00:01 · Predicted position estimated via dead reckoning from last heading + speed + metocean drift. Uncertainty ellipse: 4.2 × 1.8 nm.
T+01:30 · Sentinel-1 pass. SAR detects 1 vessel of compatible size inside the uncertainty ellipse at 55.4N -1.5W. Match probability: 0.74.
T+02:10 · RF geolocation sensor (coastal) detects strong marine radar return at 55.42N -1.52W (range 8 nm). Range ambiguous; cross-bearings needed.
T+02:30 · EO/IR gimbal tasked. Aircraft tasked from RAF Lossiemouth via pre-approved cooperative flight plan. ETA 90 minutes.

Scenario 3 · Urban Drone Swarm Defence — Central London
RF + ACOUSTIC + EO/IR + BFT EMERGENCYCOUNTER-SWARM
Trigger: Three unidentified drones detected converging on a Category A government building in central London. DEFONEOS must classify, track, predict trajectory, and recommend response — without escalating to kinetic effectors absent explicit BFT + human authorisation.
Sensor inputs

| NPCC / MET Police | C2 coordination | On-tasking |
Fusion timeline
T+00:00 · Batear array detects 3 simultaneous drone rotor signatures within 800m of target building. Distinct frequency signatures (DJI Mavic class 1, DJI Phantom class 1, custom fixed-wing class 3).
T+00:05 · PX4 RF radar confirms: 3 control links in 2.4 GHz, one also on 5.8 GHz. Bearing correlates with acoustic.
T+00:08 · EO/IR slewed. Visual classification: 2 quadcopters (commercial, possibly DJI), 1 fixed-wing. Confidence 0.92, 0.89, 0.78.
T+00:12 · Trajectory prediction: all 3 converging on building rooftop. Estimated time-to-arrival 4 min 30s.
T+00:15 · EMERGENCY BFT SESSION auto-convened. Reduced quorum (21/33) due to urgency. Recommend: (a) RF jamming authorisation request, (b) alert NPCC + MET, (c) prepare counter-drone swarm.
T+00:18 · BFT vote: 22 for, 2 against, 9 abstain. Action:RequestRFJamAuthority + Action:AlertNPCC.
T+00:30 · Senior Civil Servant (Gold command) approves RF jamming. SIGILed with SCA Ed25519 signature.
T+00:32 · RF jam activated on 2.4 + 5.8 GHz (JSP 440 compliant — non-emergency services frequencies only). All 3 drones enter controlled descent.
T+02:00 · Drones recovered in soft-landing zones. Counter-swarm never deployed (jam sufficient). Post-event forensics: 2 commercial drones modified for longer range; 1 custom built from open-source plans. No explosives. Investigation ongoing.
Defensive design choices
- No kinetic engagement in this iteration — civilian area risk too high
- RF jam limited to non-emergency bands (JSP 440 compliant)
- Human-in-the-loop for jam activation — BFT recommends, human authorises
- EO/IR evidence preserved at every step — admissible in any subsequent court
- SIGIL chain captures full decision lineage — Gold command can defend "why"
Scenario 4 · CBRN Detection — Port of Felixstowe
CHEMICAL + RADIOLOGICAL + BFT EMERGENCYPHE + DSTL
Trigger: Customs container scanner flags anomalous gamma reading on a 40ft container declared as "machine parts" from a high-risk origin. DEFONEOS must triage, escalate, and coordinate with Public Health England + DSTL.
Sensor inputs
| Source | Channel | Update |
| Port scanner | Gamma spectroscopy, neutron | Per-container |
| Met Office | Wind direction/speed (plume model) | Hourly |
| ONS demographics | Population density within plume radius | Static |
| OS Open Data | Critical infrastructure locations | Quarterly |

| PHE knowledge base | Substance ID + treatment protocols | Curated |
Fusion timeline
T+00:00 · Gamma reading 0.8 µSv/h above background, consistent with industrial source or low-grade radiological material. DEFONEOS opens CBRN incident.
T+00:30 · Isolation zone auto-defined: 50m radius. Container moved to dedicated isolation pad by remote-controlled straddle carrier.
T+02:00 · PHE specialist team dispatched. DSTL on standby. DEFONEOS plume model: worst-case wind (NNE 15 km/h), 2 km exclusion, 20 km shelter zone.
T+04:00 · Spectroscopy confirms Cs-137 (industrial, sealed source). Confidence 0.96. NOT a dispersal device — likely orphaned medical/industrial source in cargo.
T+04:30 · BFT vote: 27/33 for safe containerisation + return-to-sender per IAEA guidance. Action:ContainmentPlan + Action:AlertIAEA.
T+24:00 · Source containerised in IAEA-compliant Type B(U) package. Origin country notified via HM Customs.
Defensive design choices
- Conservative defaults — treat as dispersal until spectroscopy says otherwise
- Plume modelling + shelter-in-place auto-recommended to PHE
- DSTL escalation path always pre-built into CBRN template
- IAEA notification SIGILed with full evidence pack
Scenario 5 · National Grid Power Outage — Multi-County
SCADA + NETWORK + ECONOMIC IMPACTDSO + NG ESO
Trigger: National Grid ESO loses visibility on 3 grid supply points (GSPs) simultaneously. 240,000 customers across 3 counties lose power. DEFONEOS must triage cause, predict restoration, coordinate with DSO and emergency services.

T+00:02 · Root cause hypothesis: transmission fault on supergrid. Backup routes triggered automatically.
T+00:15 · 40% of customers restored via auto-reclose. 60% remain down (240k → 144k).
T+00:30 · DEFONEOS impact map: 23 care homes without power (auto-paged to DSO priority list), 4 water pump stations on battery, 7 cell towers on backup.
T+01:00 · BFT session: prioritise restoration sequence. 28/33 for proposed order. SIGILed.
T+02:30 · All 23 care homes restored (DSO crews + portable generators). Water utility alerted re: pump station batteries.
T+06:00 · Full restoration. Post-event: cause identified as third-party cable damage during construction. National Grid instructed to inspect similar routes.

AMBULANCE + POLICE + FIRE + AIR AMBULANCEMETHANE + JESIP
Trigger: M6 collision in Cumbria. 17 vehicles involved. Low visibility + ice. Initial 999 calls indicate 30+ casualties. DEFONEOS must implement METHANE (Major Incident Medical Hazard Assessment) + JESIP (Joint Emergency Services Interoperability) protocols automatically.
