Indian Navy P-8I Upgrade: The Indian Navy plans to test a new radar system, which will enhance its Boeing P-8I long-range maritime patrol aircraft fleet. The proposed upgrade will improve India’s control of its anti-submarine warfare capabilities and maritime reconnaissance abilities and strategic deterrent powers throughout the Indian Ocean Region.
With growing Chinese submarine deployments, expanding sea-lane competition, and rising geopolitical pressure in the Indo-Pacific, the proposed P-8I enhancement is being seen as more than a technology upgrade; it could reshape the balance of undersea awareness in the region.
The Boeing P-8I Poseidon is one of the Indian Navy’s most capable surveillance and strike platforms.
India currently operates 12 P-8I aircraft, making it one of the largest operators of the platform outside the United States. The aircraft have played a key role in tracking submarine movements, monitoring chokepoints and supporting operations from the Arabian Sea to the Bay of Bengal.
What Is the AAS Radar Upgrade?
The reported upgrade centers on the Advanced Airborne Sensor (AAS) radar concept for the P-8 family. The AAS is an advanced active electronically scanned array (AESA) radar system designed to provide:
- Wide-area maritime surveillance
- Detection of small and stealthy surface targets
- Better submarine periscope/snorkel spotting
- High-resolution ground and sea imaging
- Improved electronic intelligence support
- Simultaneous multi-target tracking
Unlike conventional maritime radars, AAS-class systems are built to scan vast ocean sectors with greater precision, speed and persistence.
If integrated on Indian P-8I aircraft, it would represent a major leap over standard surveillance capability.
Current Radar on Indian P-8I Aircraft
Indian Navy P-8Is already use the powerful AN/APY-10 radar, a proven maritime surveillance system.
The APY-10 has served India effectively for years. However, an AAS-type radar would add a new layer of deeper maritime sensing and longer-range target discovery.

Indian Navy P-8I Upgrade: Estimated Cost
No official government contract value has yet been publicly confirmed for the radar modernization alone.
Separately, India is already progressing toward acquiring six additional P-8I aircraft, with recent reports placing the broader package near US$3.5 billion. That suggests New Delhi remains committed to expanding and modernizing its maritime aviation fleet simultaneously.
Key Features
1. Superior Anti-Submarine Detection: The Indian Ocean has seen a rise in Chinese submarine activity, which has persisted for ten years. The improved radar system, together with sonobuoys and magnetic anomaly detection, and onboard processors, will increase tracking success rates.
2. Real-Time Maritime Domain Awareness: The Indian authorities gained the ability to track increased ship movements across wider ocean regions while detecting suspicious activities.
3. Chokepoint Surveillance: Critical zones could be watched more significantly through the following locations:
- Strait of Malacca
- Andaman Sea
- Arabian Sea approaches
- Gulf of Aden routes
4. Better Strike Coordination: The P-8I provides aircraft control to naval task groups, submarines, and warships, which enables them to reach their targets with increased speed.
5. Networked Warfare Edge: The upgraded aircraft now enable faster sharing of targeting information between Indian Navy destroyers and frigates and coastal command centers.
What Happens Next?
If approved, India could pursue two tracks simultaneously:
1. Upgrade existing 12 P-8I aircraft
2. Induct six additional P-8Is with newer systems
That would create one of the most powerful maritime patrol fleets in Asia.
