Arctic & Maritime Domain Awareness

See the sea — surface to seabed.

OAK Arctic turns the EW SUITE's acoustic, multi-INT fusion and geodesy libraries into the sea-picture tools a real maritime watch needs — an AIS-style vessel COP over a polar basemap, dark-vessel & anomaly triage, CPA / TCPA encounter screening, multi-INT maritime fusion, and an ASW sonar-barrier planner that sizes a sonobuoy field across a strait against a quiet submarine.

The maritime operational layer

First-principles acoustics under an operator picture

OAK Arctic sits on the suite's shared physics — sonar_model acoustics, fusion_model multi-INT correlation and world_map geodesy — and adds the tools a watch floor works from.

AIS-style vessel picture

Merchants, tankers, fishing, naval and a submerged contact — MMSI, course/speed and an AIS on/off flag, dead-reckoned forward over the trans-Arctic lane.

CPA / TCPA screening

Closest-approach distance and time between vessels; encounter screening flags shadowing, rendezvous and collision geometry.

Dark-vessel & anomaly triage

A contact held by radar / EO but squawking no AIS is DARK; plus off-lane, loitering and subsurface flags with a CLEAR / WATCH / ALERT triage.

ASW sonar barrier

Lay a line of passive sensors across a chokepoint and compute the probability a transiting submarine is detected — reusing the suite sonar equation and transmission loss.

Multi-INT maritime fusion

Correlate AIS + radar + ELINT + EO/IR reports into fused vessel tracks, flagging tracks that sensors hold but AIS does not.

Arctic chokepoints

Davis, Fram, Bering and GIUK reference gaps — the geography a northern-approaches watch is built around.

Dark-vessel & anomaly triage: AIS-off + sensor-held, off-lane, loitering, subsurface
CPA / TCPA encounter screening for shadowing and rendezvous geometry
ASW sonar-barrier planner — sonobuoy field sized against a quiet submarine, coverage improving with density

Built on the core

Sovereign, unclassified, representational

OAK Arctic is first-principles physics on a notional traffic picture — no real AIS feed and no operational vessel registry. It reuses the EW SUITE's sonar, fusion and geodesy libraries, carved into its own product tree.
