Maintaining air superiority over the Indo-Pacific region is absolutely necessary for India to preserve its hegemony over the other nations in the region. Induction of High Altitude Long-Endurance (HALE) or Medium Altitude Long-Endurance (MALE) UAVs would be essential to undertake seamless surveillance over the vast expanse of Indo-Pacific oceans and over the land mass. MQ 9A ‘Reaper’ appears to be a perfect fit for this mission.

The Defence Acquisition Council (DAC) of India, led by Defence Minister Rajnath Singh, approved the acquisition of 31 US-manufactured Remotely Piloted Aircraft Systems (RPAS) for 3 billion USD. Eight each for the Air Force and Indian Army and the rest for the Indian Navy. The initial plan was to source 18 RPAs from the US and the balance from DRDO. Later DAC could confirm the inability of DRDO in delivering indigenous RPAS on time and hence decided to go for induction of all the 31 RPAs from the US. Details of the contract is still awaited. This induction decision may be a huge setback to the efforts of DRDO, which has been trying to manufacture high-end military RPAS for the last 20 years. The acquisition and deployment of MQ 9 will be done in a phased manner.

Indian Navy has gone a step ahead by inducting two General Atomics make MQ-9B SeaGuardian drones on lease from the US to familiarise the systems and operations. These UAVs are capable of carrying out surveillance for more than 30 hours between refuelling and are currently operating out of Indian Navy’s INS Rajali airbase near Chennai. These two drones arrived in India on Nov 2020 and are on lease till Jan 2024. These RPAs have completed 10,000 hours of flying so far for various security missions. These drones have helped out existing P8I aircraft in various missions.

Since this new purchase deal could be a mix of MQ 9A Reaper, MQ 9B SeaGuardian, MQ and 9B SkyGuardian catering for the requirement of all three armed forces,  let us compare their operational capabilities and characteristics.

General Profile

General Atomics Aeronautical Systems is an affiliate of General Atomics and is the leading manufacturer of military UAV systems, radars, and electro-optics in the world. MQ 9 A/B are designed for long-endurance surveillance, reconnaissance and precision strike capabilities. The Predator series Remotely Piloted Aircraft (RPA) of General Atomics is one of the most successful military UAVs with more than seven million flying hours. The multi-role capabilities of MQ-9 have attracted the attention of Indian military commanders leading to the short-listing of RPAS by DAC. The combination of armaments that can be carried by this RPAS includes AGM-114 Hellfire (Air to Ground Missiles), GBU-12 Paveway II (Airborne Laser-Guided Bomb), GBU-38 Joint Direct Attack Munitions(Bomb Guidance Kit), GBU-49 Enhanced Paveway II ( Enhanced Dual-mode GPS and Laser Guided Bomb), and GBU-54 Laser Joint Direct Attack Munitions (Guidance Kit for Bombs). The subject platform can be operated and controlled by two remote crews (pilot and sensor/weapon operator). It can even be dismantled and transported using aircraft to remote locations for operations. The RPAS may be transferred into India without a weapon package/contract initially.

MQ-9A Reaper

Reaper is a sophisticated multi-mission RPA  powered by a turboprop engine. It has evolved out of the experience gained by General Atomics from the battle-proven Predator RPA. ‘Reaper’ is also widely known as Predator B. 

MQ-9A has an endurance of over 27 hours and a top speed of speeds of 240 Knots/ 445 Kmph and a ceiling height of 50,000 feet/15.25 Kms.

MQ-9A has evolved over the years to meet customers’ emerging needs with extended range and retrofittable capabilities such as wing-borne fuel pods and a new reinforced landing gear which has helped Reaper to increase the endurance from 27 hours to 34 hours with operational flexibility. U.S. Air Force, U.S. Department of Homeland Security, NASA, the Royal Air Force, the Italian Air Force, the French Air Force and the Spanish Air Force are operating MQ 9A.

MQ-9B SeaGuardian

MQ-9B SeaGuardian is designed for all-weather maritime operations and can be safely flown through civil airspace protocols over vast expanses of oceans. SeaGuardian is designed to meet the STANAG 4671 standards for NATO cross-platform operations and data exchange. It can be exploited by joint forces and even civil authorities to gather real-time situational awareness all weather day or night. This UAV can undertake seamless reconnaissance using long-range maritime radar, ESM, an Automatic Identification System (AIS) and a top-notch self-contained Anti-Submarine Warfare (ASW) mission kit for underwater surveillance. It has an endurance of more than 30 hours and can be controlled by satellite links beyond the horizon across the globe.

SeaGuardian has outstanding (ISR) capabilities and is the first RPAS in its class which can undertake ASW operations. The open architecture of SeaGuardian has the option to integrate sonobuoys dispensers and process sonar signatures received from deployed sonobuoys like any other manned ASW platforms.

Basic Characteristics

It has similar characteristics to MQ 9B Seaguardian.


The real challenge for the armed forces would be the exploitation of RPAS post-induction. Logistics and maintenance support for MQ 9A Reaper are major factors in the seamless exploitation of these platforms. Interoperability and data exchange with existing Russian and Indian systems is another challenge for the Armed Forces which cannot be undermined. DRDO can certainly speed up their Rustom RPAS project by learning from MQ 9A/B. Exploring possibilities of integration of native missiles and bombs would certainly narrow the dependency on the US for weapons.
