Coastal surveillance: Tanzania
Tanzania's Indian Ocean coast runs from the Kenyan border past Tanga, Dar es Salaam and the Zanzibar archipelago to the Mozambican line, fronting busy sea lanes and a wide exclusive economic zone. Coastal radar reaches only so far, and the gaps between stations are exploited daily by traffickers, smugglers and unregistered craft among the islands and channels.
Extending the picture past the last radar
A conventional coastal chain leaves blind arcs between stations, and small craft learn exactly where they are. Passive radar adds coverage without emitting, filling those arcs without advertising itself; satellite vessel detection catches movement far offshore toward the EEZ edge; and observation drones close in to confirm contacts at the quayside. Together they extend Tanzania's maritime awareness from the beaches of the mainland to the outer approaches beyond Zanzibar and Pemba.
An archipelago raises the stakes
The channels, reefs and dense small-boat traffic of the Zanzibar archipelago are especially hard to hold with radar alone, and they sit astride the routes coastal surveillance most needs to watch. This compounds with illegal fishing, smuggling and human trafficking that all exploit the same waters. A layered, low-observable picture lets the maritime forces act on early evidence rather than after a craft is already ashore.
How engagement works in Tanzania
Unstrat represents the manufacturers directly as an independent, non-aligned prime vendor: end-use certified, one accountable team, in-region sustainment. The passive radar, satellite tasking and observation drones come from makers with no alignment attached, so the maritime picture stays under Tanzanian control end to end. We would start by filling the most exploited gaps and build toward a continuous coastal picture Tanzanian operators run themselves. A briefing can identify where coverage is thinnest first.
Holding the coast where radar alone cannot
A coastal-surveillance engagement begins with a briefing that finds the thinnest coverage along the seaboard, from Tanga and Dar es Salaam to the dense channels and reefs of the Zanzibar archipelago and out toward the EEZ edge. Unstrat confirms export-control clearance and end-use before representing the manufacturers, so the passive radar, satellite detection and observation drones come through one accountable channel answerable to national forces, not a distributor. The layers are matched to real conditions: blind arcs small craft learn, island traffic that hides offenders, waters shared with fisheries, smuggling and trafficking missions. We phase the build from the most exploited gaps to a continuous picture Tanzanian operators run themselves, with localisation arrangements scoped per programme, subject to export controls and end-use approvals. In-region sustainment keeps the maritime picture protecting the coast under national control.

Adjacent priorities in Tanzania
Tanzania's exclusive economic zone stretches across a long Indian Ocean frontage from the Kenyan border past Dar es Salaam and the Zanzibar archipelago to the Mozambican line. Illegal, unreported and unregulated fishing drains that resource and undermines sovereignty over the zone, happening far offshore where patrol vessels cannot be in more than one place at a time.
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 pageDar es Salaam is Tanzania's principal gateway and a key outlet for landlocked neighbours including Zambia, the DRC and beyond, with additional traffic through Tanga, Mtwara and the Zanzibar ports. A port concentrates national trade in a small, exposed footprint: vulnerable from the water, the air and the network.

Tanzania: security context
Tanzania's priorities span its waters and its interior: protecting its exclusive economic zone and fisheries, safeguarding wildlife, and securing the ports central to its trade. It is an environment where economic, environmental and maritime security are closely linked across a broad geography.
One accountable, non-aligned partner gives Tanzania a coherent counterpart for that capability: EEZ and fisheries protection, wildlife protection and port security through a single channel, with transparent export-control handling. A security agency gains end-use certified equipment, in-region support 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 does passive radar help close the gaps around the Zanzibar archipelago?
It adds detection between existing radar stations without emitting anything a small craft can detect or avoid, so the blind arcs among the islands and channels stop being predictable. Combined with satellite detection further out, it turns an intermittent picture into a continuous one. We can map the priority gaps in a briefing.
Can coastal surveillance serve several maritime missions at once?
Yes. The same persistent picture that reveals unregistered craft also supports fisheries enforcement, counter-smuggling and the early detection of trafficking vessels, because all exploit the same waters. That multi-mission use is central to how coastal surveillance is framed for Tanzania.
Who controls the coastal picture Tanzania builds?
Tanzania does. The sensors and satellite tasking come from independent, non-aligned makers, and the data is tasked and retained nationally with no foreign feed in the loop. A briefing can walk through the sovereignty and sustainment model.
