TAPAS-BH

TAPAS-BH overview

The TAPAS-BH (Tactical Airborne Platform for Aerial Surveillance Beyond Horizon), formerly known as Rustom-2, is a medium-altitude, long-endurance unmanned aerial vehicle being developed by India's Aeronautical Development Establishment (ADE) under the Defence Research and Development Organisation (DRDO). The program aims to provide the Indian armed forces with a domestically developed MALE UAS comparable to the MQ-9 Reaper and IAI Heron TP. The aircraft features a twin-engine configuration, a wingspan of approximately 20.6 meters, and a target endurance of 18-24 hours.

The TAPAS-BH program has experienced significant delays since its inception in 2011, with the first flight occurring in 2016 and subsequent testing revealing various technical challenges. As of 2025, the program continues development with incremental flight testing and system integration. India has simultaneously pursued acquisition of foreign drones including the MQ-9B SeaGuardian to meet immediate operational requirements while the TAPAS-BH program matures. The platform's significance lies in India's strategic objective to develop indigenous MALE drone capability, reducing dependence on foreign suppliers and building domestic aerospace expertise for future advanced drone programs.
