Coastal surveillance: Greece
Greece's maritime domain is among the most fragmented anywhere: a scatter of islands, straits and long approaches across the Aegean that no chain of coastal radar can watch as a whole. Building a single picture from the beach out to the edge of the exclusive economic zone is a scale and geometry problem before it is a sensor problem.
An archipelago that defeats a radar line
A coast broken into hundreds of islands leaves any fixed radar chain with more gaps than coverage, and the emitting stations that do exist tell an observer exactly where the seams lie. Passive radar fills those seams without emitting, extending the picture into the channels between islands. Ocean surveillance satellites track vessels running dark across the wider Aegean and out to the EEZ edge, while observation drones close in to confirm the near-shore contacts around the ports and anchorages the islands depend on.
Long approaches around scattered islands
What makes the Greek case exceptional is geometry: the sheer number of islands multiplies the approaches that must be watched, and a contact can pass between coverage zones many times on a single transit. A national picture therefore has to fuse orbital, passive and near-shore layers so a vessel is held continuously rather than glimpsed and lost. Because these capabilities come from independent, non-aligned makers, the maritime picture over Greek waters is tasked and retained nationally rather than assembled from a foreign feed.
How engagement works in Greece
As an independent, non-aligned prime vendor, Unstrat fields one accountable team to add passive coverage in the channels the radar chain cannot reach, establish a satellite baseline across the Aegean, and fuse the layers into a single picture the maritime authority runs itself. Equipment is end-use certified and sustained in-region. Localisation arrangements are scoped per programme, subject to export controls and end-use approvals, so the picture stays under national control.
Building one picture across a fragmented Aegean
Engagement starts with a briefing on the geometry that defeats a fixed radar line: hundreds of islands, channels and long approaches where a contact can pass between coverage zones many times on a single transit. Before the accountable single channel offers any representation, end-use is certified and export-control approvals are settled, so the maritime picture over Greek waters stays a national asset rather than an assembled foreign feed. Capability is matched to the scale of the problem: passive radar to fill the seams between islands without emitting, ocean-surveillance satellites to track vessels running dark across the wider Aegean to the EEZ edge, and observation drones to close in and confirm the contacts around the ports and anchorages the islands depend on. Fielding is phased with in-region sustainment, adding coverage in the channels the chain cannot reach first, then fusing the layers so a vessel is held continuously rather than glimpsed and lost, an awareness advantage the maritime authority tasks and runs itself. Localisation arrangements are scoped per programme, subject to export controls and end-use approvals.

Adjacent priorities in Greece
Illegal, unreported and unregulated fishing works the edges of Greece's exclusive economic zone, where the scatter of islands and long approaches leaves stretches of water rarely reached by patrol vessels. Building a continuous, defensible record of who was fishing where, across a zone this fragmented, is a reach-and-evidence problem before it is an interception one.
Problem pagePiracy raises insurance costs, deters shipping and endangers seafarers. Space-based vessel monitoring, aerial patrol and hardened port and vessel systems let coastal states detect threats early and protect the shipping lanes their economies depend on.
Problem pageGreece's ports concentrate national and regional trade in small, exposed footprints scattered across the mainland and the islands, each vulnerable from the water, the air and the network at once. Securing those gateways end to end, where a single busy harbour handles flows an economy depends on, is a layered problem no single measure addresses.

Greece: security context
Greece's maritime geography shapes its priorities: domain awareness across the Aegean, surveillance of an exclusive economic zone dotted with islands, monitoring of borders and migration routes, and protection of critical infrastructure. It is an environment where scattered waters and long approaches demand persistent, wide-area awareness.
An accountable single-channel engagement gives Greece a coherent counterpart for those priorities: Aegean maritime domain awareness, EEZ and island surveillance, border monitoring and infrastructure protection. A defence ministry gains end-use certified equipment, disciplined export-control handling and localisation arrangements scoped per programme rather than promised in advance.
About this challenge
Coastal radar sees only so far, and gaps between stations are exploited daily. Passive radar that adds coverage without emitting, satellite vessel detection and satellite-data fisheries analytics extend the maritime picture from the beach to the edge of the EEZ.
Frequently asked questions
Why can't coastal radar cover the Aegean on its own?
Because a coast broken into hundreds of islands leaves any fixed, emitting chain with more gaps than coverage. Passive radar, satellite vessel detection and observation drones extend the picture into the channels and out to the EEZ edge. We would be glad to brief your team on filling the widest seams first.
How is a vessel held across so many islands?
By fusing orbital, passive and near-shore layers so a contact is tracked continuously as it passes between coverage zones, rather than glimpsed by one sensor and lost to the next.
Who controls the maritime picture over Greek waters?
The national maritime authority. All the layers come from independent, non-aligned makers, so the picture is tasked and retained nationally, with localisation arrangements scoped per programme and subject to export controls and end-use approvals.
