Revolutionizing Long-Range Strike Capabilities: The Case for a Heavy Unmanned Bomber

The Need for a Heavy Unmanned Bomber in India's Defence Strategy

The Indian Air Force (IAF) has been exploring the possibility of developing a heavy unmanned bomber to enhance its long-range strike capabilities. Two former IAF officers, Air Commodore Gaurav Mani Tripathi (Retd.) and Group Captain Ajay Ahlawat (Retd.), recently discussed this idea on the Airside Chat YouTube channel.

The concept of a heavy unmanned bomber is not new, and several countries have been working on similar projects. However, India's experience with the Ghatak unmanned combat aerial vehicle (UCAV) has provided valuable insights into the development of such a platform.

The Ghatak, a 2-tonne UCAV, has demonstrated its capabilities in various tests, including a successful flight of over 2 hours. Building on this experience, the IAF veterans propose a 50-tonne unmanned aircraft, powered by multiple engines, which could carry substantial payloads over long ranges.

Such a platform would offer several advantages, including a large weapons load and the benefit of being unmanned. The removal of crew would eliminate life-support systems, but it would not alleviate the challenges of certifying the aircraft's reliability and autonomy.

A long-range unmanned bomber would require advanced target acquisition and counter-air capabilities to overcome enemy defenses, particularly in heavily defended land targets and maritime operations. The speakers also emphasized the importance of secure communications and considerable autonomous capabilities to ensure the aircraft's effectiveness.

Before embarking on the development of a long-range bomber, India should carry out thorough studies into propulsion, aerodynamics, avionics, materials, and low observables. This would help identify the key challenges and opportunities in developing such a platform.

The IAF veterans also discussed the option of leveraging the Ghatak's experience to build a larger unmanned aircraft. They proposed a 50-tonne aircraft, powered by multiple engines built around the Kaveri programme, which could offer the advantage of a large weapons load and the benefit of being unmanned.

However, the development of a heavy unmanned bomber would require significant investment and resources. The speakers acknowledged that India could not afford even a small force of heavy bombers, given its current defence-modernisation costs. The support and operating costs of such aircraft would demand a significant chunk of the budget.

Despite these challenges, the IAF veterans believe that a heavy unmanned bomber could be a game-changer in India's defence strategy. It could supplement surface combatants, submarines, maritime patrol aircraft, and other surveillance aircraft, providing a credible deterrent by holding targets inside enemy territory at risk.

In the maritime domain, a long-range bomber could respond to any threat in the vast expanse of the oceans. However, the usefulness of such a platform would be dependent on its range and weapons' range, as well as target acquisition and counter-air capabilities.

The speakers made a distinction between maritime operations and attacking heavily defended land targets. They emphasized the need for advanced target acquisition and counter-air capabilities to overcome enemy defenses in both scenarios.

In conclusion, the development of a heavy unmanned bomber is a complex and challenging task. However, with thorough studies and careful planning, India could potentially develop a game-changing platform that enhances its long-range strike capabilities and provides a credible deterrent against potential threats.
