Indian drone manufacturer EndureAir Systems has unveiled VAHAK-6, a new multi-UAV mothership concept developed in collaboration with Bharat Electronics Limited (BEL). The system uses EndureAir’s SABAL 20 unmanned helicopter as an airborne carrier and command node capable of transporting and deploying up to six smaller UAVs closer to their operational area.
The concept marks a notable development in India’s unmanned warfare architecture by separating the transportation, deployment, and control functions from the smaller drones themselves. Rather than launching every micro-UAV from a ground location, VAHAK-6 is designed to carry them airborne and release them nearer to the mission zone.
According to EndureAir, the system can deploy specialized ALAKH micro-UAVs, allowing the smaller aircraft to preserve their limited endurance for operational tasks instead of using valuable battery life to travel from a distant launch point.
The architecture is based on the SABAL platform, a lightweight tandem-rotor unmanned helicopter powered by a variable-speed electric propulsion system. EndureAir identifies SABAL as a VTOL platform designed for logistics, surveillance, and reconnaissance missions, featuring BVLOS capability and modular payload options.
The ALAKH micro-UAV forms the second element of the system. EndureAir describes it as an FPV drone with an all-up weight of approximately 250 to 800 grams and a payload capacity of up to 400 grams. The platform is designed to operate in confined environments and supports GPS-free navigation, making it suitable for close-range reconnaissance and other specialized missions.
By combining these platforms, VAHAK-6 creates a distributed aerial system in which the SABAL 20 serves as both a transport platform and an airborne command node. Once deployed, the smaller UAVs can carry out independent or coordinated missions.
This approach could extend the effective operational range of micro-UAVs. Instead of consuming a significant portion of their battery endurance travelling from a launch site to the target area, the drones can be transported closer to the operational zone and use more of their available endurance for surveillance or mission execution.
VAHAK-6 could also support mixed UAV operations. EndureAir states that the system can deploy ALAKH surveillance drones alongside expendable strike-oriented variants, enabling Search, Detect, and Destroy missions from a single airborne platform.
The architecture may be particularly relevant in electronic warfare-contested and GPS-denied environments. EndureAir intends VAHAK-6 to support coordinated and distributed operations under degraded communications and navigation conditions, although the system’s operational effectiveness will depend on the resilience of its autonomy, navigation, and communication capabilities.
Another advantage of the concept is that the mothership itself does not need to be a large aircraft. A relatively compact VTOL platform could operate from locations where larger fixed-wing aircraft face greater deployment and basing limitations.
For the Indian military, VAHAK-6 could potentially support reconnaissance, border surveillance, urban operations, and battlefield sensing. The mothership could approach an area while keeping its smaller UAVs undeployed until required, before releasing them in different directions to create multiple observation points.
The multi-UAV architecture could also improve survivability and mission flexibility. The loss of one micro-UAV would not necessarily end the mission, as the mothership could deploy additional drones with different payloads and mission roles.
VAHAK-6 reflects EndureAir’s broader move toward more advanced unmanned systems. Rather than focusing solely on building larger individual drones, the concept creates a network of heterogeneous UAVs, with the mothership handling transportation, command, and deployment while smaller autonomous aircraft perform specialized tasks.
