India has raised concerns over US military support for Pakistan’s F-16 fighter fleet, highlighting the potential security risks associated with transferring sensitive military technology. The issue was discussed during Singh’s meeting with US Secretary of War Pete Hegseth on the sidelines of the ASEAN Defence Ministers’ Meeting-Plus (ADMM-Plus) in Cebu, Philippines, on October 28, 2026.
According to media reports citing officials, India expressed concern over a reported $686 million US support and modernisation package for Pakistan’s F-16 aircraft. Singh also cautioned that sensitive American technology supplied to Pakistan could potentially reach third countries.
The discussion took place as India and the United States reviewed progress under their broader defence partnership and explored further cooperation in military technology, maritime security and defence manufacturing.
What Did Rajnath Singh Say About the US F-16 Package for Pakistan?
During the meeting with Pete Hegseth, Rajnath Singh reportedly conveyed India’s objections to US support for Pakistan’s F-16 fighter aircraft.
According to reports, the Indian side highlighted two major concerns:
- Regional security: Continued support for Pakistan’s F-16 fleet has implications for India’s assessment of the regional military balance.
- Technology security: Sensitive equipment, software and military know-how supplied to Pakistan could potentially be transferred to a third country.
The technology concern was particularly significant because Pakistan maintains close defence ties with China. However, the possibility of technology reaching another country was raised as a risk, not established as an event that had occurred.
Reports also said Singh emphasised the need for a consistent international approach towards countries accused of supporting, training or financing terrorist organisations. The US side reiterated its support for India in its fight against cross-border terrorism, according to officials cited in the reports.
What Is the $686 Million US F-16 Package for Pakistan?
- The reported $686 million package concerns support and modernisation for Pakistan’s existing F-16 fighter fleet. It should not be confused with an agreement to supply Pakistan with an entirely new fleet of F-16 aircraft.
- According to The Tribune, the package was cleared by the US Congress in December 2025 and is intended to extend the operational life of Pakistan’s F-16 fleet to 2040. Reported elements include avionics-related upgrades, communications equipment, cryptographic systems, software support, training and logistical assistance.
- The precise scope of the package should be distinguished from the details of earlier US F-16 sustainment arrangements.
- For example, in September 2022, the US Defense Security Cooperation Agency (DSCA) notified Congress of a possible $450 million sustainment case for Pakistan’s F-16 fleet. That earlier proposal covered engineering, technical and logistical support and explicitly stated that it did not include new capabilities, weapons or munitions. It was a separate case from the more recent package reported in 2026.
Why Is India Concerned About Pakistan’s F-16 Fleet?
India’s concerns relate to the strategic environment in South Asia and the possible implications of advanced military support to a neighbouring country.
1. Regional Military Balance
- Pakistan operates F-16 fighter aircraft as part of its air force. Maintaining and modernising existing aircraft can help sustain their availability and operational usefulness.
- India therefore evaluates foreign military assistance to Pakistan in the context of its wider security environment. The significance of any particular upgrade depends on the systems involved, their capabilities and how they affect operational readiness.
2. Protection of Sensitive Military Technology
- Modern fighter aircraft depend on complex combinations of avionics, software, communications equipment, maintenance systems and technical documentation.
- India has reportedly warned that sensitive US-origin technology supplied to Pakistan could potentially be exposed to third countries. Such a risk is relevant to defence-export controls and the protection of military technology.
- The concern does not, by itself, prove that Pakistan has transferred US technology to another country.
3. Pakistan’s Defence Relationship With China
- Pakistan and China maintain a close defence relationship and cooperate in several areas of military equipment and development.
- Against this background, India has raised questions about safeguards designed to prevent sensitive technology supplied by one country from being accessed by another. Reports described China as a possible reference in the discussion, although the alleged transfer of US technology to China has not been established by the reporting.
Rajnath Singh and Pete Hegseth Discuss India–US Defence Cooperation
- The meeting between Rajnath Singh and Pete Hegseth was not limited to Pakistan’s F-16 aircraft.
- According to reports, the two sides reviewed progress under the 10-year India–US Major Defence Partnership Framework and discussed military technology, information sharing, co-production, military exchanges, maritime security and defence supply chains.
- These areas reflect the broader effort to strengthen defence cooperation between New Delhi and Washington while addressing their respective security priorities. The F-16 issue illustrates how differences over US military support to Pakistan can coexist with continued India–US defence engagement.
What Is the F-16 Fighting Falcon?
- The F-16 Fighting Falcon is a single-engine, multirole combat aircraft developed by General Dynamics, with production and support later handled by Lockheed Martin.
- It is designed for air-to-air combat and air-to-ground missions. The aircraft has been operated by the United States and several other countries, including Pakistan.
- A sustainment package generally focuses on keeping aircraft operational through maintenance, spare parts, technical services, software support and related upgrades. Depending on its scope, a modernisation package may also update selected onboard systems.
- Such support is different from the purchase of new aircraft. The details of each package must be assessed individually to determine what equipment and capabilities are included.
