Summary of "Neptun Shadow: задачі морського дивізіону СБС, підводний дрон "Марічка", загроза російських БЕКів"
Interview overview
- Subject: Velbot, commander of the 443rd Separate Marine Division “Neptune’s Shadow”, 9th Unmanned Systems Forces Brigade.
- Purpose: Description of the origin, development, capabilities and challenges of Ukrainian naval unmanned systems.
- Format: Interview with an unnamed host/presenter.
Origins and evolution
- Early experimentation began in 2022 using improvised conversions (scooters, FPV boats) with the initial objective of sinking ships.
- Successive teams refined those improvisations into purpose-built surface and underwater drones (examples: Magura, C Baby, Dzyga, Viy).
- The program consolidated from many small teams into roughly five persistent core teams, constrained by funding and operational demand.
Types, roles and capabilities
Primary and secondary roles
- Primary: strike (kamikaze) missions against ships, landing craft and infrastructure.
- Secondary/possible roles: reconnaissance, mine-clearing and bottom surveys, logistics (cargo delivery), casualty evacuation concepts, and patrol/support for manned boats.
Surface drones
- Designs vary in range, speed and payload:
- Early fiber-optic kamikaze examples were around 25 kg.
- Later water-jet designs (e.g., Dzyga) carry larger payloads (~70 kg), reach ~40 km/h and have ranges up to ~70 km.
- Some surface platforms are larger carriers designed to deploy smaller kamikaze boats.
Underwater drones
- Larger underwater kamikaze designs (e.g., Marichka) target very long ranges (claims up to ~1,000 km) and heavy warheads (claims up to ~1,000 kg) intended for major targets (bridges, ports, large ships).
- Underwater platforms emphasize low-noise propulsion and inertial navigation for stealth. Many designs are still in trials or await funding/production.
Communications and navigation
- Three main communication links are used: fiber-optic tether, LTE, and satellite.
- Fiber-optic control is valued for low observability but increases mission time due to slower transit; it is also preferred where stealth is required.
- Redundancy is standard: multiple comms and autopilot-to-coordinates fallback modes if links fail.
- Underwater navigation/communications are the toughest problems: radio/wireless do not propagate well underwater, so systems rely on inertial navigation and occasional undisclosed supplementary methods; seabed topology and changing conditions complicate routing.
Operational ranges (typical)
- Small surface boats (radio control): up to ~30 km.
- Extended communications: up to ~50–100 km using different comms methods.
- Ambitious underwater endurance claims: up to many hundreds or even ~1,000 km (still being refined and verified).
Operational use, results and tactics
- Ukrainian naval drones have achieved notable combat success, influencing Russian behavior in the Black Sea (reduced large-ship operations and altered deployments).
- Velbot claims many successful strikes on Russian watercraft and argues that Ukraine demonstrated temporary sea superiority in certain periods.
- Tactics are rapidly evolving and are a primary interest for foreign partners; Ukraine is effectively a combat testing ground for naval drone tactics and operational integration.
- Coordination challenges exist because multiple Ukrainian services operate naval drones (Main Intelligence Directorate, SBU, Naval Forces, Unmanned Systems Forces, and some special operations units). Centralized deconfliction is needed to prevent wasted effort and fratricide; joint operations are increasing but imperfect.
Production, logistics and the ecosystem
- Many components and hulls are manufactured domestically, including 3D-printed hulls and in-house electronics/architecture.
- Reported limited production capability: roughly 30–40 boards per month depending on model and orders.
- Most manufacturers prioritize military requirements over profit; funding and demand determine which producers survive and scale.
- The naval-drone ecosystem requires far more than pilots: engineers, armament/sapper teams, navigators, mechanics, drivers, analysts, cover groups, medics and logistics. Effective operations demand planning, reconnaissance, and support personnel.
Technical and operational challenges
- Underwater navigation and communications are the hardest technical problems.
- Environmental factors (seabed/topography, currents, changing conditions) complicate routing and mission planning.
- Russian detection, spoofing and countermeasures are significant threats; both sides rapidly learn and adapt.
- Planning is difficult because maritime targets move and conditions change; timely intelligence and cross-unit coordination are essential.
Threat assessment and enemy capabilities
- Russia is developing and beginning to field its own naval drones (including surface and river variants).
- Velbot cautions not to underestimate Russian capabilities even if their operational use has appeared limited so far.
- Western naval drone systems exist but are generally far more expensive; Ukrainian systems are comparatively cheap, combat-proven and of particular tactical interest to European partners who emphasize tactics over hardware.
Personnel, unit formation and training
- Velbot’s marine division (focused on unmanned systems) is being formed: about 20% staffed so far, actively recruiting diverse specialties.
- Emphasis on placing personnel where skills best fit rather than assigning desired roles.
- Human factors matter: stressful conditions, short-notice absences and variable preparedness can affect mission outcomes.
International interest and cooperation
- Baltic and other European partners observe Ukrainian experience and request tactical expertise.
- Some offers to cooperate/produce were limited by small domestic demand in partner countries.
- Some intelligence and support come from partners, but resource constraints limit how much foreign assistance can replace indigenous capability.
Funding and procurement
- Advanced platforms (e.g., Marichka) have been developed but await funding to enter mass production.
- Ukrainian manufacturers largely respond to specific military requirements, with procurement driven by operational demand and available funds.
Conclusions (as expressed by Velbot)
Ukrainian naval drones have matured from improvised tools into a diverse family of combat-capable surface and underwater systems. They are cost-effective, combat-proven and tactically influential. Major technical hurdles remain — underwater comms/navigation, scaling production and inter-service coordination — but Ukrainian forces and industry are rapidly adapting and iterating based on operational needs.
