Maritime Defense Without Blind Spots

Indrajaal Maritime is a modular soft-kill system designed to protect naval vessels and critical port assets from the full spectrum of modern drone threats. Whether it’s FPVs in the sky or USVs skimming below the surface, Maritime ensures seamless detection, rapid classification, and autonomous neutralization—before threats can strike.

With rugged hardware and AI-driven decision-making, it’s built to operate under pressure, adapt on the fly, and defend with zero delay.

Maritime Drone Incidents

Drones Are Now the Biggest Maritime Threat

Today’s maritime battlefront isn’t just above the waterline. Swarming FPVs, loitering munitions, DIY UAVs, and autonomous USVs are being deployed to disable, spy, and destroy. Indrajaal Maritime was born from this rising threat curve.

Houthi USV attacks in the Red Sea
Since late 2023, Houthi rebels in Yemen have ramped up their use of unmanned surface vessels (USVs) and unmanned aerial vehicles (UAVs) to strike both commercial and military ships in the Red Sea. Armed with explosives, these drones are deployed in coordinated swarm attacks, often hitting from air and sea simultaneously to confuse radar and overwhelm modern naval defenses.
Close-In Weapon Systems (CIWS), interceptor missiles, and electronic warfare suites have had some success — but they’re not foolproof. Delayed response times and saturation limits leave ships exposed, making these low-cost, high-impact tactics a serious headache for even the most advanced fleets.
Drone Incursions Along India’s Coast
India has faced a rising number of drone incursions near key naval assets along its western coastline, especially around sensitive zones like Karwar, Mumbai, and strategic offshore installations. These include low-flying UAVs, suspected to be conducting surveillance or testing response times. While most are neutralized or tracked by naval radars and coastal surveillance systems, the threat is evolving.
GPS-denied drones, potential satellite uplink relays, and stealthy low-RCS designs are increasingly used to bypass detection. India’s response has included boosting electronic warfare capabilities, deploying anti-drone jammers, and integrating AI-based threat detection into its maritime command network — but gaps remain, especially against multi-vector swarm tactics.
FPV Drones Targeting Russian Naval Fleet
The Russian Black Sea Fleet in Sevastopol has come under repeated First-Person View (FPV) drone attacks, marking a shift in asymmetric naval warfare. Ukrainian forces have used small, fast, low-cost FPV drones—both aerial and surface—to target ships, fuel depots, and port infrastructure. These drones are manually piloted via real-time video, allowing precision strikes on moving or partially shielded assets.
Despite heavy defenses including jammers, CIWS, and decoys, many attacks have landed hits, crippling patrol boats and damaging dry docks. The attacks have forced Russia to reposition parts of its fleet and rewire its coastal defense posture—proof that $10K drones can challenge billion-dollar warships.

Comprehensive protection

Multi-Domain Protection, One Integrated System

Indrajaal Maritime defends on two fronts simultaneously — surface and aerial. Its cyber-takeover unit hijacks rogue signals, while GNSS spoofing and FPV jamming confuse and disable the rest. All threats are analyzed and mitigated in real time.

Own the Seas. Deny the Skies.

DETECTION (<8km)

Using portable RF sensors and a growing drone signature library, Trooper scans up to 5 km in all directions—detecting rogue signals early in the mission.

TRACKING (<3km)

Once a drone is detected, SkyOS initiates real-time tracking within a 3 km zone, locking in on speed, altitude, trajectory, and RF signature — while the Direction Finder pinpoints the controller’s source location.

IDENTIFICATION(<3km)

Using portable RF sensors and a growing drone signature library, Trooper scans up to 5 km in all directions—detecting rogue signals early in the mission.

MITIGATION (<2km)

Using portable RF sensors and a growing drone signature library, Trooper scans up to 5 km in all directions—detecting rogue signals early in the mission.

AI-powered Tech

SkyOSTM: Central Command for the High Seas

SkyOSTM is the nerve center of Indrajaal Maritime — integrating radar, RF, EO/IR, and sonar feeds into a single, live-operating picture. From tracking low-flying FPVs to identifying USVs skimming just below the surface, it classifies threats, predicts intent, and assigns the fastest, most effective countermeasure.

Coordinating every Maritime unit in your fleet, SkyOSTM ensures seamless defense of vessels, ports, and coastal assets — turning the vast, unpredictable ocean into a controlled battlespace.
