Design and Development, qualification, certification and trials of NSUAS class Multi Utility Long Endurance (MULE) drones for use in maritime domain for C4ISR duties. MULE should be deployable from ships and should be recoverable from launching as well as an alternate platform afloat up to sea state 3 (essential) or sea state 4 (desirable). The RPA will be launched from a ship and used for surveillance including SIGINT, COMINT (desirable),Target Acquisition, Reconnaissance and building MDA (Maritime Domain Awareness) around a Task Group. The secondary roles of RPA would include anti-piracy, anti-terrorist activities and assistance in Search and Rescue (SAR). The payload should be modular and include inter alia EO/IR, AIS, Maritime Patrol Radar, EW and communication relay. The minimum payload capacity should be 50 Kgs. The endurance of the RPA should preferably be 12 hrs with standard payload plus one special payload (EO/IR + AIS) and would depend on the payload carried.
