Exercise Yudh Abhyas 2026: 22nd Edition India-USA at Mahajan & Auli | UPSC

Why in News

The 22nd edition of Exercise Yudh Abhyas — India's largest annual bilateral military exercise with the United States — commenced in September 2026. For the first time in the series' history, the exercise is being conducted across two simultaneous theatres: Mahajan Field Firing Ranges, Rajasthan (desert warfare) and Auli, Uttarakhand (high-altitude Himalayan terrain, approximately 95 km from the Line of Actual Control with China). The exercise runs until 28 September 2026.

Background

Exercise Yudh Abhyas (meaning "War Practice" or "War Training" in Hindi) is an annual bilateral military exercise between the Indian Army and the United States Army. It is the largest and longest-running bilateral exercise between the two countries' armies, conducted alternately in India and the United States. The series began in 2004 under the framework of the India-US Defence Technology and Trade Initiative (DTTI) and has grown to become a cornerstone of the India-US Major Defence Partnership.

India and the US signed the Logistics Exchange Memorandum of Agreement (LEMOA) in 2016, Communications Compatibility and Security Agreement (COMCASA) in 2018, and Basic Exchange and Cooperation Agreement (BECA) in 2020 — collectively called the "foundational agreements" that underpin joint military interoperability. Yudh Abhyas operationalises this interoperability at the unit level.

Current Developments

Two-Theatre Format (First-Ever)

The 22nd edition's novel two-theatre structure tests interoperability across:

Mahajan Field Firing Ranges, Bikaner, Rajasthan: Simulating desert and semi-arid conditions — relevant to sub-conventional conflict scenarios in India's western sector.
Auli, Chamoli district, Uttarakhand (~3,500 metres altitude): Simulating high-altitude mountain warfare — directly relevant to India's northern sector along the Line of Actual Control (LAC) with China.

Conducting the exercise simultaneously in desert and high-altitude environments tests the armies' ability to coordinate across multiple domains and geographies — a critical requirement in modern multi-theatre warfare concepts.

Participating Forces

Indian Army: Infantry battalion and supporting arms (exact unit not disclosed).
US Army: 11th Airborne Division (based at Fort Wainwright, Alaska — specialised in cold-weather and mountain warfare) and the 3rd Multi-Domain Task Force (3MDTF) (specialised in cross-domain integration: land, air, cyber, space, and electronic warfare).

Focus Areas

Joint tactical operations in diverse terrains.
Multi-domain operations (land, air, cyber, electronic warfare integration).
Humanitarian Assistance and Disaster Relief (HADR) interoperability.
Counter-terrorism and counter-insurgency tactics.
Emerging technologies: drones (Unmanned Aerial Systems — UAS), counter-drone systems, and AI-assisted situational awareness.

Constitutional Provisions

Under Article 73, the executive power of the Union extends to matters in the Union List, including defence (Entry 1 — defence of India, armed forces) and foreign affairs. The Cabinet Committee on Security (CCS), chaired by the Prime Minister, approves defence exercises and agreements. Article 53 vests supreme command of the Defence Forces in the President, exercised through the Union government. India's bilateral defence exercises are conducted under government-to-government (G2G) frameworks, not requiring parliamentary ratification.

Legal Framework

India-US Major Defence Partnership (2016): Elevated defence relationship enabling co-development, co-production, and advanced interoperability.
LEMOA (2016): Logistics Exchange MoA — allows each country's forces to access the other's military logistics facilities for supplies and services.
COMCASA (2018): Communications Compatibility and Security Agreement — enables encrypted military communications interoperability.
BECA (2020): Basic Exchange and Cooperation Agreement — provides India access to US geospatial intelligence data for precision targeting.
Initiative on Critical and Emerging Technology (iCET, 2023): Extends India-US cooperation to AI, quantum computing, semiconductors, and advanced defence systems.

Institutional Framework

Ministry of Defence (MoD): Oversees all bilateral exercises; coordinates with MEA for diplomatic protocols.
Integrated Defence Staff (IDS): Coordinates tri-service aspects; the Chief of Defence Staff (CDS) oversees theatre-level interoperability.
US Indo-Pacific Command (INDOPACOM): US military command responsible for the Asia-Pacific; Yudh Abhyas falls under its purview.
US Army Pacific (USARPAC): Coordinates Yudh Abhyas on the American side.

Economic Dimensions

India's bilateral defence trade with the US has grown from near-zero in 2008 to over USD 22 billion (cumulative by 2025), driven by procurement of C-17 Globemaster, C-130J Super Hercules, P-8I Neptune, AH-64 Apache, CH-47 Chinook, and MH-60R Seahawk platforms. Joint exercises like Yudh Abhyas build familiarity with US platforms, facilitating future procurement decisions. Under iCET (2023), defence co-production agreements for GE F414 engines (for TEJAS Mk2) and Stryker infantry vehicles are in progress.

The exercise at Auli also serves India's broader defence-industrial goals: testing indigenous Indian Army equipment (ATAGS artillery, AK-203 rifles, Excalibur drones) alongside US systems builds operational evidence for technology validation and export promotions.

International Relations

Yudh Abhyas 2026's two-theatre format carries significant strategic messaging:

Auli / LAC proximity: Conducting high-altitude warfare training ~95 km from the LAC signals enhanced India-US readiness for mountain-domain scenarios, without explicitly targeting any third party.
Quad alignment: Yudh Abhyas complements India's concurrent military exercises with Japan (Yama Sakura, Veer Guardian) and Australia (Austrahind, Malabar) — reflecting the Quad's military interoperability architecture.
India's strategic autonomy: India maintains Yudh Abhyas simultaneously with exercises involving Russia (INDRA), Russia-led SCO (Tsentr), and other partners — reflecting India's policy of multi-alignment, not exclusive alliance.

Challenges

Technology transfer limits: US export-control laws (ITAR — International Traffic in Arms Regulations) still restrict certain technologies even within the Major Defence Partner framework.
Interoperability gaps: Different communication protocols, tactical doctrine, and command structures require sustained exercises to bridge.
China's perception: High-altitude exercises near the LAC, while defensive, invite diplomatic pushback from China.

Government Initiatives

Major Defence Partner status (2016): India is the only non-treaty ally to hold this designation from the US.
iCET (Initiative on Critical and Emerging Technology, 2023): Extends the partnership to AI, quantum, semiconductors, space, and defence tech.
Defence Production and Export Promotion Policy (DPEPP) 2020: Targets USD 5 billion in defence exports by 2025; US-trained interoperable units strengthen India's export case.
Theatre Command Restructuring: India's ongoing creation of integrated theatre commands (Mountain, Western, Maritime) will eventually align better with the US multi-domain task force model exercised in Yudh Abhyas.

Way Forward

The Parliamentary Standing Committee on Defence has recommended institutionalising bilateral exercises as part of a long-term defence cooperation roadmap rather than ad hoc iterations. The NITI Aayog Technology Vision 2035 emphasises dual-use technology collaboration. India should: (a) leverage the 3MDTF presence at Yudh Abhyas to advance India's own multi-domain operations doctrine; (b) expand the exercise to include air force and navy elements for a fully joint tri-service format; (c) use the BECA geospatial data access in realistic Himalayan scenarios; and (d) build on LEMOA to establish reciprocal logistics access at Andaman & Nicobar Command for US Indo-Pacific operations.

FAQ

What is Exercise Yudh Abhyas?: Yudh Abhyas is India's largest annual bilateral military exercise with the United States Army. It began in 2004 and is conducted alternately in India and the US. The 22nd edition (2026) is held in India across two simultaneous theatres — Mahajan (Rajasthan) and Auli (Uttarakhand).
What are the foundational India-US defence agreements?: Three agreements form the foundation: LEMOA (2016) — logistics access; COMCASA (2018) — encrypted communications interoperability; BECA (2020) — geospatial intelligence sharing for precision targeting.
What is India's "Major Defence Partner" status?: Granted by the US Congress in 2016, India is the only non-treaty ally to hold this designation. It enables India to receive advanced defence technology at a level comparable to US treaty allies, facilitating co-production and co-development of defence equipment.
