Coastal surveillance: Saudi Arabia
Saudi Arabia is one of the few states with two long, strategically distinct coastlines, the Red Sea to the west and the Gulf to the east, each with predictable gaps between radar stations. Watching both approaches as a whole, out to the edge of the EEZ, is a scale problem conventional coastal radar cannot solve alone.
Two seas, more gaps than coverage
The Kingdom's Red Sea and Gulf coasts are watched by chains of radar stations whose fixed, emitting nature tells an adversary exactly where the coverage begins and ends, leaving the mid-water and far EEZ effectively unwatched. Passive Radar fills those seams without emitting, extending the coastal picture into the gaps without advertising the new coverage. Ocean surveillance satellites track vessels running dark out to the edge of the zone, and satellite-based Fish Detection adds fisheries analytics that separate legitimate fishing from suspect activity near shore.
Distinct threat pictures on each coast
What makes the Saudi case unusual is that the two coasts carry different threat pictures (the Red Sea's approaches to shipping lanes and the Gulf's dense traffic and proximity to contested waters), so a single national picture must fuse two very different maritime environments. That fusion compounds with the Kingdom's energy export dependence, since both coasts host terminals whose approaches must be watched continuously. Because all three capabilities are independent and non-aligned, the coastal picture is tasked and owned by the Kingdom rather than assembled from a foreign feed.
How engagement works in Saudi Arabia
As an independent, non-aligned prime vendor, Unstrat fields one accountable team to add passive coverage where the radar chain is thinnest, establish a satellite baseline over both approaches, and fuse the layers into a single picture the Kingdom runs itself. Equipment is end-use certified and sustained in-region. The non-aligned position ensures the coastal picture over the Kingdom's own waters is retained under national control, not filtered or withdrawn by an outside partner.
Fusing two seas into one picture the Kingdom runs
Watching the Red Sea and Gulf approaches as a whole starts with a briefing on where each radar chain is thinnest and how the two coasts' distinct threat pictures must be fused. Unstrat acts as a single accountable channel to the makers and confirms export controls and end-use before any representation. Capability is matched to the operator's real conditions: passive coverage in the seams without emitting, an ocean-surveillance satellite baseline out to the EEZ, and satellite-based fisheries analytics sorting legitimate fishing from suspect activity near shore. A programme establishes coverage where the gaps are widest, then fuses the layers into a single picture the Kingdom runs itself, with sustainment phased in-region. This protects the advantage of following a contact from open water to the quayside on either coast. Localisation arrangements are scoped per programme, subject to export controls and end-use approvals.

Adjacent priorities in Saudi Arabia
Illegal, unreported and unregulated fishing drains coastal economies and undermines sovereignty over the exclusive economic zone. Persistent satellite surveillance, satellite-data fisheries analytics and aerial ISR give maritime authorities the picture they need to intercept offenders, without depending on a major power's data feed.
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 pageSaudi Arabia's ports concentrate the Kingdom's trade and much of its energy export on both the Red Sea and the Gulf, in compact footprints exposed from the water, the air and the network at once. A disruption at a major terminal ripples through supply chains, customs revenue and energy exports within days.

Saudi Arabia: security context
Saudi Arabia's security environment is shaped by the scale of what it must protect: energy infrastructure dispersed across great distances, airspace that must account for low, slow and inexpensive threats, and sovereign space ambitions that extend the picture beyond the horizon. Each priority asks for reach, persistence and a proportionate defensive posture.
An accountable, non-aligned engagement gives the Kingdom a coherent counterpart for those priorities: energy protection, counter-drone airspace defence and sovereign space assurance through a single channel. A defence ministry gains end-use certified equipment, in-region sustainment 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
How can Saudi Arabia watch both its Red Sea and Gulf coasts as one picture?
By fusing passive radar in the seams of each radar chain, satellite vessel tracking out to the EEZ, and satellite-based fisheries analytics near shore into a single national picture. That lets the Kingdom follow a contact from open water to the quayside on either coast. We would welcome the chance to brief your team on sequencing coverage across both seas.
How do you cover the gaps between the Kingdom's coastal radar stations?
Passive Radar exploits ambient signals to detect and track without emitting, filling the predictable seams between fixed, emitting stations. It extends the coastal picture into the gaps without advertising where the new coverage is or offering anything to jam.
Is the coastal picture dependent on a foreign data feed?
No. The passive radar, satellites and fisheries analytics are all independent and non-aligned, so the picture over the Kingdom's waters is tasked and owned nationally, rather than stitched together from a feed a foreign partner could filter or withdraw.
