The Nigerian Air Force (NAF) has expanded its unmanned aerial systems (UAS) portfolio with the induction of Sky Whale Max hybrid vertical take-off and landing (VTOL) drones from Chinese manufacturer Shenzhen Yangda Security Company Limited. The acquisition package includes complete systems and hands-on training, underscoring Nigeria’s ongoing effort to leverage cost-effective Chinese platforms to confront persistent security challenges ranging from Boko Haram insurgency in the northeast to banditry and oil theft in the south.
Training, conducted in two phases during August 2025, focused on assembly, mission planning, flight operations and maintenance. NAF personnel successfully executed a 100-kilometre test flight with real-time video transmission, showcasing the platform’s endurance and reliability. According to Yangda sales manager Lyn Qian, the Sky Whale Max represents an “integrated solution” designed to streamline intelligence gathering, reducing delays in relaying battlefield data to command centres.
Technical Capabilities
The Sky Whale Max is designed as a heavy-lift hybrid drone optimised for both endurance and flexibility. Its dual propulsion system uses battery power for quiet VTOL operations and a gasoline generator for extended cruise phases. The drone can carry up to 15 kilograms of payload, stay aloft for 10 hours, cover more than 100 kilometres and reach speeds of 120 kilometres per hour. With a noise signature under 60 decibels at 100 metres altitude, it remains discreet in operations. The airframe has a 4.9 metre tandem-wing configuration, weighs 25 kilograms empty and supports a maximum take-off weight of 65 kilograms.
The modular design allows for rapid assembly—wings can be attached in under 20 minutes—enabling forward deployment from austere locations such as Maiduguri or Port Harcourt. Advanced navigation systems, including differential GPS and inertial sensors, support operations in GPS-denied environments while the gimbal bay accommodates electro-optical, infrared or multi-sensor payloads for surveillance, reconnaissance and light cargo delivery.
Operational Context
For Nigeria, the Sky Whale Max fills a crucial niche between runway-dependent fixed-wing drones and shorter-endurance electric models. Its versatility suits missions such as border surveillance along Nigeria’s 4,047 kilometre frontier with Niger, Chad, Cameroon and Benin. It can also conduct counterterrorism reconnaissance in the Lake Chad Basin, provide logistics support for remote outposts to reduce convoy exposure and carry out urban and coastal patrols including pipeline and critical infrastructure monitoring.
Part of a Broader Drone Strategy
The acquisition continues Nigeria’s decade-long reliance on Chinese UAVs. The NAF already operates the CH-3B, CH-4 and Wing Loong II drones for surveillance and strike missions supporting Operation Hadin Kai against Boko Haram. These systems have been critical in identifying militant camps and directing precision strikes.
The Sky Whale Max complements this fleet by offering a hybrid solution for rapid deployment and persistent surveillance in areas where runways are scarce or mobility is critical. Its emphasis on training also aligns with Nigeria’s strategy to build indigenous capability, reducing reliance on foreign technicians and lowering sustainment costs estimated at $50,000 per unit annually.
