The defence cooperation highlight of Prime Minister Narendra Modi’s state visit to the US last week was the agreement between US firm General Electric (GE) and India’s aerospace giant, Hindustan Aeronautics Limited (HAL), to manufacture GE F-414 jet engines in India.
Besides powering HAL’s Tejas Mark 2 fighter, the F-414 could also be chosen to power other combat aircraft being acquired by the Indian Air Force (IAF) and Indian Navy.
HAL-GE’s India plant could eventually produce close to a thousand F-414 engines. Besides 126 Tejas Mark 2 fighters, the IAF could choose these engines for 114 twin-engine, multi-role fighter aircraft it is acquiring from the international market.
The Indian Navy could also select the F-414 to power the 57 twin-engine multi-role carrier borne aircraft (MRCBF) it is buying for its aircraft carriers; and for an unspecified number of twin-engine Tejas carrier deck fighters.
A power pack must also be chosen for the futuristic Advanced Medium Combat Aircraft (AMCA) that the Defence Research and Development Organisation (DRDO) is indigenously developing. The DRDO hopes to uprate the indigenous Kaveri engine to power the twin-engine AMCA. However, if the Kaveri cannot meet the design challenges involved, an uprated F-414 might be chosen for the AMCA.
A fighter’s engine costs roughly 20-30 per cent of the total aircraft’s cost. In August 2021, GE and HAL signed a Rs 5,375 crore contract for 99 F-404-IN20 engines to power 83 Tejas Mark 1A fighters it is building for the IAF.
GE will build these F-404-IN20 engines in its US plant and supply them over-the-counter to HAL. In contrast, the more powerful and technologically advanced F-414 engines will be built in India with manufacturing technology provided by GE.
“This agreement to manufacture F-414 engines in India will enable greater transfer of US jet engine technology than ever before. The leaders committed their governments… to support the advancement of this unprecedented co-production and technology transfer proposal,” said the Joint Statement issued after summit talks between India’s Prime Minister Narendra Modi and US President Joe Biden.
It remains unclear whether the Modi-Biden agreement and the GE-HAL deal will allow the transfer by GE of key jet engine technologies such as single crystal blades and combustion chamber materials.
During President Barack Obama’s visit to India for Republic Day 2015, the two countries created a joint working group (JWG) for cooperation in two high-technology areas: aircraft carrier design technology, and gas turbine engine technology.
Both these projects made little headway. In 2019, GE backed away from sharing sensitive intellectual property (IP). in October 2019, US Under Secretary of Defense Ellen Lord told the media that the JWG for fighter engines had been scrapped.
“We could not come to an understanding of what exportable (jet engine) technology would be useful to the Indians,” said Lord. “And we ran into a challenge in terms of US export control,” she added
Acquisition of MQ-9B drones
In order to keep track of enemy targets, the defence ministry has been pursuing acquisition of 31 MQ-9B drones from US firm, General Atomics. While these will be tri-service assets, they will comprise of 16 Sky Guardians for use over land and 15 Sea Guardians for use over oceanic territories.
The MQ-9B is the newest generation of remotely piloted aircraft systems (RPAS), which deliver persistent intelligence, surveillance, and reconnaissance (ISR) around the globe, extending the Indian military’s ability to observe and strike faraway targets.
This drone flies over-the-horizon for up to 40 hours in all types of weather. It can be safely integrated into civil airspace, enabling joint forces and civil authorities to deliver real-time situational awareness anywhere in the world — day or night.
The drone’s avionics and sensors include the Lynx multi-mode radar, an advanced electro-optical/infrared (EO/IR) sensor, and automatic take-off and landing.
Sky Guardian and Sea Guardian drones allow for multi-domain missions, including humanitarian assistance and disaster relief (HADR), search and rescue (SAR), border enforcement, and airborne early warning (AEW).
The Sea Guardian additionally provides anti-surface warfare and anti-submarine warfare mission kits, along with airborne mine counter measures.
These High Altitude Long Endurance (HALE) drones are being procured through the foreign military sale (FMS) route. The Pentagon has indicated an estimated cost of $3,072 million, but the final price remains to be negotiated.
India’s Ministry of Defence says: “(We) will compare the acquisition cost with the best price offered by General Atomics to other countries. The procurement is in progress and would be completed as per the laid down procedure.”
As part of the procurement, General Atomics will establish a “comprehensive global MRO facility” in India to support [India’s] long-term goals to boost indigenous defence capabilities.
Basing and repair for US ships
Modi and Biden also welcomed India’s emergence as “a hub for maintenance and repair for forward deployed US Navy assets and the conclusion of Master Ship Repair Agreements with Indian shipyards.”
This will allow the US Navy to expedite contracting for mid-voyage and emergent repair of its warships deployed in the Indian Ocean and the Western Pacific.
In their “Defense Industrial Roadmap,” both countries have agreed to work together for the creation of logistic, repair, and maintenance infrastructure for aircrafts and vessels in India.
In sum, Modi and Biden affirmed a vision of India and US as among the closest partners in the world.
“The India-US Comprehensive Global and Strategic Partnership is anchored in a new level of trust and mutual understanding and enriched by the warm bonds of family and friendship that inextricably link our countries together,” said the joint statement.

The F414 is also a potential powerplant for emerging platforms such as the Korean KF-X and other potential applications.
