India’s Fighter Jet Dilemma: F-35 Stealth Fighter or Russian Su-57?

The recent offer of the F-35 stealth fighter aircraft by the United States to India has ignited a major debate. Should India accept this offer, considering the time required to develop its own fifth-generation fighter aircraft, or should it instead opt for Russia’s Su-57? This decision is crucial as the Indian Air Force (IAF) needs to bolster its fighter squadron numbers with cutting-edge technology. While the situation isn’t yet alarming, strategic experts remain deeply concerned about the future of India’s air combat capabilities.

The Geopolitical Angle: US, China, and Pakistan

Historically, the US has been more concerned about the Chinese threat to India than about Pakistan. Despite India’s strong opposition, Washington has consistently supplied Pakistan with advanced weaponry. However, whenever China has posed a significant challenge to India, the US has stepped in to offer support.

This trend is not new. Declassified documents from the US State Department Archives reveal that after the 1962 Sino-Indian War, the US conducted a thorough assessment of India’s air defense capabilities against China. In that war, India refrained from using the IAF in an offensive role, fearing retaliation from China’s air force. The US reports from the 1960s indicated that China had a limited air strike capability against India due to logistical constraints, yet the threat remained real.

India’s Air Force Needs: Why a Fifth-Generation Fighter is Crucial

The IAF currently operates a mix of fourth-generation aircraft like the Rafale, Su-30MKI, and Tejas, but the absence of a true fifth-generation stealth fighter is a glaring gap. The two primary options before India are:

1. Lockheed Martin F-35 Lightning II

• Advantages: The F-35 is one of the most advanced stealth fighters globally, featuring cutting-edge avionics, network-centric warfare capabilities, and interoperability with allied forces.
• Challenges: The procurement of the F-35 could bring geopolitical strings attached, as the US may impose operational restrictions on its use. Additionally, integrating US defense technology with India’s existing Russian-origin systems, such as the S-400 missile defense system, could be problematic.

2. Sukhoi Su-57 Felon

• Advantages: The Su-57, Russia’s answer to stealth air superiority, is designed for both air dominance and strike missions. India’s long-standing defense relationship with Russia makes this option appealing, as it would integrate smoothly with existing IAF assets.
• Challenges: The Su-57 program has faced delays and reliability concerns. Compared to the F-35, the aircraft lacks a fully developed stealth profile and an advanced global support network.

A Historical Perspective: The US and India’s Fighter Jet Dilemma

Looking back at the 1960s, the US had offered India several aircraft options to counter the Chinese air threat, including the F-104 Starfighter, F-6A Skyray, and F-5 Freedom Fighter. However, the Indian government ultimately chose the Soviet MiG-21, which went on to become a backbone of the IAF for decades. The US had also proposed the HF-24 Marut project as a potential indigenous fighter program, but India struggled with technological constraints at the time.

The US and UK had even planned to provide emergency air defense units for India, a strategy echoed today in India’s evolving partnerships with Quad nations (US, Japan, Australia, and India).

The Way Forward: Key Considerations for India

As India evaluates its next-generation fighter aircraft, several key factors must be taken into account:

1. Strategic Autonomy vs. Dependence

• The F-35 comes with a reliance on the US for maintenance, software updates, and parts. This could limit India’s strategic independence.
• The Su-57, though an alternative, lacks global support infrastructure and its long-term viability is uncertain.

2. India’s Indigenous Fighter Programs

• The Advanced Medium Combat Aircraft (AMCA), India’s indigenous fifth-generation fighter program, is still in early stages of development. Even with the best-case scenario, AMCA will take at least a decade to become operational.
• In the interim, a stopgap solution is required, making the F-35 vs. Su-57 debate even more critical.

3. Cost and Logistics

• The F-35 is significantly more expensive than the Su-57, with each jet costing around $80 million to $100 million, excluding operational costs.
• The Su-57 is cheaper but comes with risks regarding performance and long-term technological support.

4. Geopolitical Fallout

• If India chooses the F-35, it could strain India-Russia defense ties, which remain strong despite India’s growing engagement with Western nations.
• If India opts for the Su-57, it may face diplomatic pressure from the US, particularly with regard to defense sanctions under CAATSA (Countering America’s Adversaries Through Sanctions Act).
