Pakistan’s Answer to INS Dhruv? PNS Rizwan Opens Hidden Intelligence War in Arabian Sea

(DEFENCE SECURITY ASIA) — Pakistan may have quietly opened an entirely new front in its strategic rivalry with India by deploying its first dedicated missile-tracking and intelligence-gathering ship into the Arabian Sea.

The deployment of PNS Rizwan suggests Islamabad no longer intends merely to observe India’s missile and naval activity from coastal radar stations vulnerable to distance, geography and limited line-of-sight coverage.

Instead, Pakistan now appears determined to push its surveillance network far into the Arabian Sea, creating a mobile intelligence platform capable of secretly monitoring ballistic missiles, satellites and military communications.

That shift matters because the Arabian Sea increasingly represents the most important maritime corridor in South Asia, linking Indian missile test ranges, Pakistan’s naval bases, Gulf shipping routes and wider Indian Ocean deployments.

Pakistan Navy has not formally announced the deployment, yet multiple Pakistani and defence media reports indicate that PNS Rizwan has been operating in the Arabian Sea since early April.

The vessel’s appearance coincides with recent Pakistan Navy exercises involving live missile launches, loitering munitions, unmanned systems and maritime strike operations across the North Arabian Sea.

The timing has therefore intensified speculation that Islamabad intends to use PNS Rizwan both to support its own missile tests and to observe regional strategic activity beyond Pakistan’s coastline.

More importantly, many analysts increasingly interpret the ship as Pakistan’s direct response to India’s INS Dhruv, the much larger Indian missile-tracking vessel commissioned in 2021.

If that assessment proves correct, South Asia may be entering a hidden new phase of competition in which both countries seek not merely to build missiles, but to track, analyse and exploit them.

The arrival of PNS Rizwan also places Pakistan inside an exclusive group of countries possessing dedicated missile range instrumentation ships, including the United States, Russia, China and India.

For Indian defence planners, the ship’s emergence introduces a new uncertainty because future missile tests and naval deployments may now be observed continuously from international waters.

For Pakistan, however, PNS Rizwan represents a rare opportunity to reduce the intelligence imbalance with India without immediately entering an expensive and politically visible naval arms race.

Pakistan Quietly Built PNS Rizwan With Chinese Assistance

PNS Rizwan was built in China by Fujian Mawei Shipbuilding Co., Ltd., highlighting the increasingly sophisticated military-technical cooperation between Islamabad and Beijing across the maritime domain.

The ship was delivered to Pakistan Navy in June 2023, although its arrival was deliberately managed through an unusually discreet route designed to minimise international attention.

During that transit, the vessel reportedly stopped in Jakarta before eventually reaching Pakistan, creating the impression that Islamabad wanted to conceal both the ship’s configuration and intended role.

Pakistan officially classifies the vessel as the lead ship of the Rizwan-class missile-tracking ships, although commercial tracking services often identify it only as an offshore support vessel.

That ambiguity appears intentional because disguising a missile-tracking ship as a civilian-style auxiliary vessel complicates foreign attempts to monitor its operations and deployment patterns.

The vessel has also frequently operated with its Automatic Identification System switched off, reinforcing assessments that Pakistan intends to use PNS Rizwan primarily for covert surveillance missions.

Those low-profile operating patterns mirror the behaviour of other strategic intelligence ships, which often minimise electronic signatures while collecting data during missile tests or naval exercises.

Chinese support is especially significant because Beijing already possesses extensive experience operating similar vessels capable of tracking ballistic missiles, satellites and re-entry vehicles across vast oceanic distances.

For Pakistan, cooperation with China therefore provides not merely a ship, but access to a much broader surveillance and maritime intelligence ecosystem.

PNS Rizwan Could Secretly Track Indian Missile Tests

The most important question surrounding PNS Rizwan is not where it was built, but what Islamabad intends to do with it once deployed near Indian waters.

Most analysts believe the ship’s primary purpose is to monitor ballistic missile launches, capture telemetry and analyse the technical performance of foreign missile systems.

PNS Rizwan carries three prominent radar domes mounted across its superstructure, indicating the presence of advanced tracking radars, antennas and electronic intelligence systems.

Those radomes reportedly house X-band and S-band active electronically scanned array radars capable of observing high-speed targets at long range across the Arabian Sea.

The X-band radar is especially important because it can provide highly detailed tracking of missile behaviour, including warhead separation, decoy deployment and terminal re-entry patterns.

That means PNS Rizwan could theoretically observe not only that a missile has been launched, but also precisely how it performs during different stages of flight.

During a future Indian missile test, the ship might potentially gather data regarding propulsion efficiency, guidance corrections, radar signatures, warhead release timing and re-entry characteristics.

Such information would allow Pakistan to improve its own missile defences and potentially refine the performance of its own strategic weapons.

The vessel could also reportedly monitor satellites and space-based systems, giving Pakistan an additional layer of space domain awareness previously unavailable through coastal radar alone.

By combining missile tracking, satellite monitoring and signals intelligence aboard one ship, Pakistan has created a platform capable of extending its strategic reach far beyond national waters.

Islamabad’s Covert Answer to India’s INS Dhruv

The strongest evidence that PNS Rizwan is intended to counter India comes from comparisons with INS Dhruv, India’s dedicated missile-tracking and satellite-monitoring ship.

INS Dhruv entered Indian service in 2021 and immediately transformed India’s ability to observe missile launches, monitor satellites and support ballistic missile defence operations.

At approximately 175 metres long, INS Dhruv is roughly twice the size of PNS Rizwan and carries a much larger sensor and communications architecture.

Nevertheless, Pakistan appears to have chosen a different approach centred upon concealment, mobility and lower-cost asymmetric capability rather than direct numerical parity.

PNS Rizwan measures approximately 87.2 metres in length with a beam of nineteen metres, making it significantly smaller and potentially harder to identify during operations.

That smaller size may actually provide certain operational advantages because the ship can blend more easily into normal maritime traffic across the Arabian Sea.

Where INS Dhruv operates as a conspicuous strategic platform, PNS Rizwan appears designed to function more discreetly while still collecting highly valuable telemetry and intelligence.

Both vessels nevertheless perform broadly similar missions involving missile tracking, satellite monitoring, electronic intelligence and early warning during periods of heightened regional tension.

The existence of both ships suggests South Asia is entering a new intelligence race in which Pakistan and India compete not only through missiles, but through the ability to monitor each other’s strategic systems.

Arabian Sea Becoming South Asia’s New Intelligence Battlefield

The Arabian Sea has traditionally been viewed primarily as a naval and commercial shipping corridor, yet PNS Rizwan’s deployment suggests it is rapidly becoming a surveillance battlespace.

From the Arabian Sea, Pakistan gains access to a broad maritime position overlooking Indian naval movements, missile test trajectories and major strategic shipping routes.

The region already hosts intense military activity because India, Pakistan, Iran and extra-regional powers all operate naval forces, submarines and long-range strike systems there.

Pakistan’s recent naval exercises in the North Arabian Sea involved missile firings, loitering munitions and unmanned systems, creating an ideal opportunity for PNS Rizwan to gather telemetry.

The ship therefore may not merely be observing foreign activity, but also supporting Pakistan’s own efforts to test and improve increasingly advanced missile systems.

The vessel’s reported ability to conduct electronic intelligence, signals intelligence and communications interception further expands its usefulness during periods of crisis.

That capability means PNS Rizwan could potentially detect radar emissions, military communications and other electronic activity long before conventional forces recognise an emerging threat.

The ship may therefore provide Pakistan with a valuable early-warning layer capable of reducing reaction time during a future missile confrontation or naval crisis.

Because the vessel can operate independently for extended periods, Islamabad now possesses a mobile strategic sensor capable of shifting rapidly toward whichever regional flashpoint becomes most important.

PNS Rizwan May Be Only the Beginning

Despite the ship’s growing visibility, remarkably little is publicly known regarding PNS Rizwan’s true technical specifications or operational capabilities.

Pakistan Navy has released almost no official information regarding the ship’s radar range, sensor power, displacement or exact electronic warfare configuration.

Open-source estimates nevertheless suggest the vessel displaces approximately 5,000 tonnes, although that figure remains impossible to verify through publicly available information.

The secrecy surrounding the ship is itself strategically important because uncertainty forces regional rivals to assume PNS Rizwan may possess more sophisticated capabilities than presently understood.

Several analysts also believe the vessel likely operates in coordination with Chinese-origin surveillance systems and potentially wider Chinese maritime intelligence networks.

If that assumption is accurate, Pakistan could eventually integrate PNS Rizwan into a much larger Chinese-supported surveillance architecture extending across the Indian Ocean.

Such an arrangement would dramatically expand Pakistan’s ability to observe regional missile tests, naval movements and satellite activity without depending entirely upon domestic systems.

The broader implication is that PNS Rizwan may represent only the first stage of a larger Pakistani effort to create a permanent ocean-based missile-tracking capability.

If Islamabad eventually acquires additional vessels or more advanced sensors, the Arabian Sea could evolve into a continuous intelligence battlefield where every missile launch and naval movement is instantly monitored.

In that scenario, PNS Rizwan would not be remembered merely as Pakistan’s first spy ship, but as the platform that quietly triggered South Asia’s next strategic surveillance race.
