How many P-8I maritime patrol aircraft does India currently operate for anti-submarine warfare in the Indian Ocean Region?
Explanation · Correct answer C
Boeing delivered India's 12th P-8I in February 2022. The P-8I is the Indian Navy's long-range maritime reconnaissance and anti-submarine warfare aircraft, so the operating fleet count in this question is 12.

Frequently asked questions
What is the P-8I Poseidon aircraft and why is India acquiring more of them?
The P-8I Poseidon is a long-range, multi-mission maritime patrol aircraft manufactured by Boeing, specifically configured for India. It is designed for anti-submarine warfare (ASW), maritime surveillance, and intelligence gathering. India is acquiring six additional P-8I aircraft to strengthen its surveillance and deterrence capability in the Indian Ocean Region (IOR), where China's naval presence has been steadily increasing. India already operates 12 P-8Is, and the new deal — valued at nearly $4 billion — will bring the total fleet to 18.
What is the Defence Technology and Trade Initiative (DTTI) and how does the P-8I deal relate to it?
The Defence Technology and Trade Initiative (DTTI) is a bilateral framework launched in 2012 between India and the United States to fast-track defence co-production and technology transfer. It aims to move beyond traditional buyer-seller relationships toward joint development and manufacturing. The P-8I deal reflects the deepening partnership under DTTI, as both nations work to co-develop advanced military platforms. DTTI also covers areas like aircraft carrier technology, jet engine development, and intelligence sharing.
What strategic significance does India's Indian Ocean Region (IOR) presence hold, and how do the P-8I aircraft help?
The Indian Ocean Region is vital for global trade — nearly 80% of the world's oil trade passes through it. India's geostrategic location at the IOR's centre makes it a natural security provider. China's expanding naval footprint (through the 'String of Pearls' strategy involving ports in Pakistan, Sri Lanka, and Bangladesh) poses a strategic challenge. The P-8I's long-range surveillance capability — covering over 2,200 km — allows India to monitor submarine and surface vessel movements across the IOR, acting as a force multiplier for maritime security.
What other defence equipment was discussed alongside the P-8I deal during the September 2025 US defence delegation visit?
Along with the P-8I maritime patrol aircraft deal for the Indian Navy, the September 2025 US defence delegation visit to New Delhi (September 16–19) also covered discussions on CH-47F Chinook helicopters for the Indian Air Force. The Chinook is a heavy-lift tandem rotor helicopter used for troop transport, artillery emplacement, and humanitarian operations in high-altitude terrains, making it suitable for India's Himalayan theatre requirements.
How does the India-US defence relationship compare to India's traditional defence partnerships, and what does this deal signify?
Historically, India relied heavily on Russia for defence equipment under long-standing ties. However, since the signing of foundational defence agreements — LEMOA (2016), COMCASA (2018), and BECA (2020) — India has significantly deepened its defence partnership with the US. The P-8I deal (worth ~$4 billion) is one of the largest US-India defence transactions and signals India's strategic pivot toward diversifying its defence supply chain. It also reflects India's 'strategic autonomy' doctrine — maintaining independent ties with both Russia and the US.
