DRDO’s Air-Droppable Container-ADC-150.
DRDO-Indian Navy’s ADC-150 Air Droppable Container Tested from P-8I Aircraft: Off the Coast of Goa — In a significant boost to India’s maritime logistics and emergency response capabilities, the Defence Research and Development Organisation (DRDO) and the Indian Navy have successfully conducted a series of in-flight release trials of the indigenous Air Droppable Container ‘ADC-150’ from a Boeing P-8I Poseidon maritime patrol aircraft.
The trials, conducted between February 21 and March 1, 2026, took place off the coast of Goa under varying and extreme release conditions. A total of four successful drops were executed, validating the system’s performance across operational scenarios.
The ADC-150 system has been designed to deliver payloads of up to 150 kilograms, enabling aircraft to rapidly dispatch critical supplies to naval ships operating far from the coastline. Defence officials say the capability will significantly enhance the navy’s operational logistics, particularly during emergencies or when ships deployed in deep waters require urgent resupply.
Enhancing blue-water logistics and emergency response
Modern naval operations often involve ships operating hundreds or even thousands of kilometres from shore bases. In such circumstances, delivering urgent supplies—ranging from spare parts to medical equipment—can become a major logistical challenge.
The ADC-150 system addresses this gap by enabling maritime patrol aircraft to deliver critical cargo directly to vessels at sea. The container can carry essential stores, life-saving medical kits, communication equipment or other mission-critical payloads required by ships facing emergencies.
Once released from the aircraft, the container deploys a parachute system that ensures a controlled descent before splashdown in the sea, allowing naval personnel to retrieve the payload safely.
The system is particularly valuable in blue-water operations, where naval platforms remain deployed for extended periods and may require rapid logistical support without returning to port.

Multi-lab collaboration across India’s defence R&D network
The development of the ADC-150 reflects a collaborative effort across several laboratories within India’s defence research ecosystem.
The Naval Science and Technological Laboratory (NSTL) in Visakhapatnam served as the nodal laboratory overseeing the project and coordinating the trials.
The parachute delivery system used for the container was developed by the Aerial Delivery Research and Development Establishment (ADRDE) located in Agra, a specialised DRDO laboratory focusing on aerial delivery systems and parachute technologies.
Airworthiness certification and flight clearance for the trials were provided by the Centre for Military Airworthiness and Certification in Bengaluru, which ensures that defence aviation systems meet stringent safety and operational standards.
Instrumentation support for monitoring the performance of the system during the trials was provided by the Defence Research and Development Laboratory in Hyderabad.
Accelerated development to meet naval requirements
Officials involved in the project said the ADC-150 system was designed and qualified within a relatively short timeframe to meet specific operational requirements of the Indian Navy.
The development program included design validation, integration with the P-8I aircraft platform, and a series of controlled flight trials to test the system under different release conditions. These conditions simulated operational scenarios such as varying altitudes, aircraft speeds and environmental factors.
The successful completion of the four in-flight trials marks the final stage of development testing for the system.
Following the successful validation, defence officials indicated that the ADC-150 is expected to be inducted into operational service with the Indian Navy in the near future.

Strengthening indigenous defence logistics capabilities
The successful trials represent another step forward in India’s push for indigenous defence technologies under broader self-reliance initiatives.
The Boeing P-8I Poseidon, which serves as the Indian Navy’s primary long-range maritime patrol and anti-submarine warfare aircraft, plays a key role in surveillance, reconnaissance and maritime security operations across the Indian Ocean region.
Integrating an indigenous air-droppable logistics system with the aircraft significantly expands its operational utility, enabling it not only to conduct surveillance and patrol missions but also to support deployed naval assets with emergency supplies.
Defence analysts note that the ADC-150 could become a valuable tool for humanitarian missions as well, including disaster relief operations at sea, search-and-rescue missions and emergency medical supply drops.
With the successful completion of the trials, the ADC-150 system is poised to become an important addition to India’s naval logistics toolkit, enhancing the ability of maritime forces to respond rapidly to emergencies and sustain long-range operations across the country’s vast maritime domain.
