Why the IAF Should Keep the Jaguar Jet Beyond 2035: Retired Pilot's Insights on Its Unique Low-Altitude Stealth Capabilities

The Jaguar strike aircraft, a mainstay of the Indian Air Force (IAF) since the late 1970s, has long been celebrated for its unique capabilities. But now, with plans to retire the fleet by 2035, there's a growing debate about whether it's too soon to phase out this remarkable aircraft. A recent article by retired IAF Jaguar pilot Vijainder K Thakur in the Eurasian Times argues passionately for extending the Jaguar's service life, highlighting its distinct advantages in modern warfare.

A Stealthy Contender in Low-Altitude Operations

One of the Jaguar's most striking qualities is its ability to operate at low altitudes. Thakur points out that the aircraft's ability to fly close to the ground makes it stealthier than even some of the most advanced jets, like the F-22 Raptor, in certain scenarios. This isn't due to some magical cloaking device, but rather because at lower altitudes, the Jaguar can blend into the natural terrain and avoid detection by enemy radar more effectively than aircraft designed primarily for high-altitude stealth.

This low-flying ability is particularly valuable in an age where sophisticated air defense systems have become increasingly deadly. Modern radar systems, especially those employed in conflict zones like Ukraine, are highly sensitive to high-flying aircraft. However, they can struggle to detect and engage jets that remain close to the earth, navigating through valleys and using the terrain to mask their approach. Here, the Jaguar, with its rugged design and robust airframe, proves to be an asset that newer, more delicate aircraft might struggle to match.

Why Retire the Jaguar?

The current plan to retire the Jaguar fleet by 2035 stems from concerns over aging airframes, increased maintenance costs, and the aircraft's relatively limited ability to evolve with cutting-edge technology. However, Thakur argues that these concerns, while valid, can be addressed through a comprehensive Service Life Extension Program (SLEP). Such programs would involve reinforcing the airframe and updating key systems, effectively giving the Jaguars a new lease on life.

Upgrading the Power Plant: The HTFE-25 Engine

One of the most critical upgrades proposed by Thakur involves the engine. Currently powered by the Rolls-Royce Adour Mk.811 engines, the Jaguars could benefit greatly from an upgrade to a more powerful variant. Thakur suggests that Hindustan Aeronautics Limited (HAL) could retrofit the fleet with a reheat version of the HTFE-25 engine, which is currently under development in India. The reheat variant would significantly enhance the aircraft's performance, range, and payload capacity, making it even more versatile in combat scenarios.

Alternatively, upgrading the existing Adour engines to a higher thrust variant could also extend the aircraft's range and endurance. While these are challenging propositions without the original equipment manufacturer's support, they are not impossible. If HAL can navigate the technical hurdles, these modifications could keep the Jaguars in the air well beyond 2035.

Enhanced Combat Capabilities with DARIN Upgrades

The Jaguar is far from obsolete, thanks in part to the DARIN (Display Attack Ranging Inertial Navigation) series of upgrades. The latest DARIN-3 upgrade has equipped the Jaguar with a sophisticated array of avionics, including an Active Electronically Scanned Array (AESA) radar, which significantly boosts its situational awareness and combat effectiveness. Additionally, the upgraded Jaguars can carry advanced weaponry like the RAMPAGE air-to-ground missile and Smart Anti-Airfield Weapon (SAAW), making them formidable in both air-to-ground and anti-radiation roles.

These upgrades, coupled with the restoration of in-flight refueling capabilities, have allowed the Jaguar to remain an integral part of the IAF's network-centric warfare strategy. Thakur argues that these enhancements demonstrate how the focus in modern air warfare has shifted toward avionics and weapon systems, making the Jaguar more relevant than ever.

Balancing Costs with Operational Advantages

While extending the Jaguar's service life will undoubtedly incur costs, Thakur emphasizes that these must be weighed against the operational advantages the aircraft brings to the table. The DARIN-3 upgrade alone showcases India's indigenous capabilities in upgrading older platforms with state-of-the-art technologies. The economic argument, therefore, isn't just about the cost of maintenance or upgrades; it's about ensuring the IAF retains a versatile, multi-role strike platform that can effectively deter adversaries in various combat scenarios.

Conclusion: A Future for the Jaguar Beyond 2035?

Thakur's call to keep the Jaguar flying beyond 2035 is grounded in a deep understanding of its unique capabilities and the evolving demands of modern aerial combat. With strategic planning, targeted upgrades, and perhaps a bit of bold thinking, the IAF could continue to leverage the Jaguar's strengths for years to come. As defense budgets tighten and adversaries grow bolder, retaining this proven platform could ensure that the IAF remains ready and able to meet the challenges of an unpredictable future.

By keeping the Jaguar in the air, the IAF wouldn't just be preserving a piece of its past; it would be securing a key component of its future arsenal.
