Iran’s Shadow Over the Gulf: Tehran’s “Open Secret” Plan to Strike US AN/TPY-2 Radars in UAE, Qatar, Saudi Arabia and Turkey Amid Trump Escalation

(DEFENCE SECURITY ASIA) — As geopolitical volatility deepens across the Middle East under renewed Trump-era confrontation with Tehran, defense analysts, intelligence officials, and regional policymakers increasingly describe an “open secret” that Iran views the destruction of US-operated AN/TPY-2 radar systems in Qatar, Saudi Arabia, United Arab Emirates and Turkey as a near-certain retaliatory measure should these states fail to restrain Washington’s posture.

This assessment is grounded not in conjecture but in explicit Iranian warnings directed at Gulf capitals and Ankara, coupled with Tehran’s strategic recognition that disabling these high-resolution X-band radars would critically degrade the layered missile defense architecture protecting US forces, regional allies, and critical infrastructure across the Gulf.

Ali Shamkhani, adviser to Supreme Leader Ayatollah Ali Khamenei, underscored this deterrent framing when he declared, “Any interventionist hand that gets too close to the security of Iran will be cut,” a statement widely interpreted within diplomatic circles as a direct warning to host nations of American missile defense infrastructure.

 

Hameed Reza Moqaddam Far, senior adviser to the Islamic Revolutionary Guard Corps (IRGC) commander, expanded that threat posture in a live broadcast, warning that retaliation could extend not only to US military bases but to real estate assets in the UAE linked to Donald Trump and his family, asserting such action would “personally devastate him,” thereby blending military deterrence with political signaling.

President Donald Trump, in a January 28 address announcing the deployment of what he termed a “massive armada” toward Iranian waters, framed the escalation within demands for a new nuclear agreement, a posture that Tehran perceives as coercive escalation rather than diplomatic engagement.

The June 2025 US airstrikes on Iranian nuclear sites and Iran’s subsequent targeting of Al Udeid Air Base in Qatar transformed rhetorical hostility into kinetic exchange, reinforcing Iranian calculations that forward-based US assets, including radar systems, are legitimate retaliatory nodes within its deterrence doctrine.

Regional intelligence reporting indicates Tehran has formally communicated to Qatar and Saudi Arabia its intent to target American assets, including radar installations, if further US strikes occur, a claim reinforced by Professor Mehran Kamrava’s observation that “Iran has explicitly warned Doha and Riyadh it would retaliate against American targets in those countries.”

Within this context, the AN/TPY-2 radars represent not merely surveillance systems but the foundational sensors enabling Terminal High Altitude Area Defense (THAAD) and Patriot batteries to intercept ballistic threats, meaning their loss would fundamentally reshape the strategic balance between Iranian missile capabilities and Gulf-based defensive networks.

Defence Security Asia assesses that the debate is no longer about hypothetical escalation but about the structural vulnerability of a missile defense architecture dependent on a limited number of high-value radar nodes situated within direct range of Iran’s expanding ballistic missile arsenal.

Escalating US-Iran Tensions and the Strategic Logic of Radar Targeting

The re-election of Donald Trump has recalibrated US-Iran relations toward confrontation, with demands for a new nuclear deal coupled to visible military deployments, creating a deterrence environment reminiscent of earlier brinkmanship but amplified by recent kinetic exchanges.

Trump’s warning during a Fox Business interview, delivered as US naval forces moved into what he described as “striking distance,” reinforced Tehran’s perception that preemptive or coercive military options remain active components of Washington’s regional strategy.

Iran’s retaliatory strike on Al Udeid Air Base in June 2025, following US airstrikes on its nuclear facilities, signaled that Tehran is willing to engage in calibrated counterstrikes against high-value US installations rather than limiting itself to proxy-based responses.

Riyadh’s announcement that it would not allow its airspace to be used for US actions against Iran illustrates Gulf states’ strategic dilemma, balancing alliance commitments against fear of Iranian retaliation targeting critical infrastructure and energy facilities.

The 2019 drone assault on Saudi oil facilities, although predating the current cycle, continues to shape Gulf threat perceptions by demonstrating Iran’s capacity to disrupt global energy markets through asymmetric strikes.

Turkey’s hosting of a TPY-2 radar in Malatya Province introduces additional complexity, as Ankara must navigate NATO obligations while managing regional ties and domestic political sensitivities regarding alignment with US missile defense initiatives.

Tehran’s signaling that US military bases on Gulf soil would be struck if Washington initiates attacks establishes a clear conditional deterrence framework, in which host nations become indirect participants in US-Iran escalation dynamics.

Within this framework, radar systems are particularly attractive targets because their destruction would degrade early-warning timelines, compressing reaction windows for interceptors and increasing the probability of successful Iranian missile penetration.

The inclusion of radar installations within Iran’s retaliatory calculus suggests a shift from symbolic or limited retaliation toward operational targeting of enabling systems that underpin US and allied defensive capacity.

This strategic logic reflects a broader Iranian doctrine emphasizing denial of adversary advantages rather than solely maximizing offensive reach, thereby reframing the AN/TPY-2 radars as critical nodes within a contest of sensor dominance.

 

 

The AN/TPY-2 Radar: High-Resolution Sensor at the Center of Gulf Missile Defense

The AN/TPY-2 radar, developed by Raytheon Technologies, forms a central component of the US Ballistic Missile Defense System (BMDS), providing high-resolution X-band tracking of ballistic missiles across boost, midcourse, and terminal phases.

Operating in forward-based mode, the radar can detect and track ballistic missiles at ranges exceeding 3,000 kilometers, extending early-warning timelines for allies by minutes that can determine the success or failure of intercept operations.

Its active electronically scanned array (AESA) architecture allows discrimination between warheads and decoys, enabling interceptors to prioritize lethal objects within complex threat environments characterized by countermeasures and debris.

Gen. Jack Keane (ret.) emphasized its indispensability, stating, “Without this radar, missile defense becomes very problematic,” a reflection of the radar’s role in cueing systems such as Patriot and Aegis, and by extension THAAD batteries deployed across the Gulf.

The radar’s deployment in Turkey since 2011 has provided early detection of Iranian launches, effectively extending defensive depth for NATO and regional partners while simultaneously exposing the installation to Iranian targeting calculus.

In Qatar, the AN/TPY-2 supports THAAD deployments at Al Udeid Air Base, a central hub for US Central Command operations, meaning its destruction would have operational consequences beyond national defense and into theater-level command dynamics.

Saudi Arabia and the UAE rely on similar radar-linked networks to counter Houthi missile and drone threats, integrating TPY-2 data into Patriot and THAAD intercept sequences that form the backbone of their air and missile defense posture.

With only approximately a dozen AN/TPY-2 radars produced globally, each installation represents a scarce strategic asset, making replacement timelines lengthy and elevating the strategic cost of even a single successful Iranian strike.

Upgrades incorporating Gallium Nitride (GaN) technology enhance detection sensitivity, yet analysts note persistent challenges against hypersonic threats such as Iran’s Fattah missile, reportedly capable of speeds between Mach 13 and Mach 15.

Farzan Sabet of the Geneva Graduate Institute captured the structural risk succinctly when he warned that while attacks on energy infrastructure would be disruptive, the loss of these radars “could cripple missile defenses,” underscoring their systemic centrality.

THAAD Deployments and Structural Vulnerabilities in High-Altitude Defense

The Terminal High Altitude Area Defense (THAAD) system, developed by Lockheed Martin, relies on the AN/TPY-2 radar for precision tracking and engagement, using hit-to-kill interceptors to neutralize ballistic missiles during their terminal phase.

Each THAAD battery typically comprises six launchers, up to 48 interceptors, a fire control unit, and an AN/TPY-2 radar, providing coverage of approximately 200 kilometers in radius and engagement altitudes exceeding 150 kilometers.

In response to escalating tensions in 2026, the United States has deployed additional THAAD batteries to the UAE, Qatar, Saudi Arabia, Jordan, Kuwait, and Bahrain, forming what officials describe as the largest regional reinforcement since the Iraq War.

These deployments, combined with Patriot systems for lower-altitude threats, create a layered defense architecture intended to mitigate risks of Iranian retaliation following previous exchanges.

However, global scarcity of operational THAAD batteries, estimated at eight to ten worldwide, constrains flexibility and means redeployments strain global commitments.

A US defense official noted, “THAAD batteries are designed to intercept long-range ballistic missiles at high altitudes, while Patriot systems counter shorter-range threats,” illustrating the complementary yet finite structure of the layered system.

Analysts assess that while THAAD performs effectively against conventional ballistic trajectories, it faces increasing stress from hypersonic systems and potential saturation attacks involving multiple simultaneous launches.

The 12-day conflict with Israel in June 2025 reportedly tested regional defenses, prompting urgent US reinforcements and highlighting the reality that missile defense effectiveness depends on sensor integrity as much as interceptor availability.

Without precise cueing from AN/TPY-2 radars, THAAD intercept probabilities decline significantly, as engagement windows narrow and discrimination between warheads and decoys becomes less reliable.

The structural dependency of interceptors on radar cueing reinforces why Iranian targeting doctrine reportedly prioritizes radar nodes as the first echelon of attack rather than intercept batteries themselves.

Iran’s Expanding Missile Arsenal and Deterrence Doctrine

Iran possesses what is widely described as the largest ballistic missile stockpile in the Middle East, exceeding 3,000 missiles as of early 2026, with ranges up to 2,500 kilometers capable of reaching Israel, Gulf states, and US bases.

Key systems include the Sejil with ranges between 2,000 and 2,500 kilometers and speeds exceeding 17,000 kilometers per hour, alongside the Emad, Ghadr, Shahab-3, Khorramshahr, Kheibar, and the hypersonic Fattah-1 unveiled in 2023.

The Fattah-1’s maneuverability and hypersonic velocity complicate interception calculations, particularly when combined with depressed trajectories designed to reduce detection windows.

Following losses during the June 2025 conflict, Iranian stockpiles reportedly declined from approximately 2,500 missiles to between 1,000 and 1,200, but rapid production estimated at up to 300 missiles per month aims to restore levels to between 1,800 and 2,000 within months.

Major General Abdolrahim Mousavi stated, “By upgrading its ballistic missiles in all technical dimensions, Iran has been able to strengthen its deterrence power,” reinforcing Tehran’s framing of its arsenal as defensive rather than expansionist.

Iranian officials have declared the missile program “non-negotiable,” positioning it as a central pillar of deterrence against perceived US and Israeli threats.

Reports suggest that Iran’s strategy emphasizes overwhelming defenses with salvos, targeting radars to blind interceptors before launching follow-on barrages.

The reported July 2025 destruction of a US early-warning radar in Qatar, despite claims of interception, is cited as evidence that Tehran is willing to test and exploit vulnerabilities within radar-dependent defense networks.

Iran’s rejection of restrictions on intercontinental ballistic missile development introduces longer-term implications, as potential ICBM capability could extend deterrence reach beyond the Middle East to Europe and potentially the United States.

Collectively, these capabilities underpin the credibility of the “open secret” narrative, transforming rhetorical threats into plausible operational planning scenarios grounded in demonstrated missile capacity.

Strategic Implications for the Gulf, NATO, and Global Stability

The destruction of AN/TPY-2 radars in the UAE, Qatar, Saudi Arabia, and Turkey would generate cascading vulnerabilities within the integrated BMDS network, reducing early-warning timelines and increasing uncertainty in intercept outcomes.

Remote sensor cueing extends battlespace depth; without it, defenders lose critical minutes necessary for discrimination, launch decision-making, and interceptor allocation.

For Gulf states, hosting US missile defense infrastructure simultaneously enhances protection and increases exposure, creating a strategic paradox wherein defensive alignment invites retaliatory targeting.

Saudi Arabia and the UAE’s reluctance to allow their airspace for US operations against Iran reflects this calculus, as leaders weigh alliance credibility against domestic vulnerability.

Turkey’s position is further complicated by NATO obligations and regional balancing, with the Malatya radar serving alliance interests while attracting Iranian scrutiny.

Financial implications of radar loss are significant; each AN/TPY-2 radar is valued in the hundreds of millions of US dollars, with replacement and integration costs potentially exceeding US$500 million (approximately RM1.9 billion at an exchange rate of US$1 = RM3.8), excluding broader infrastructure and deployment expenses.

Similarly, a single THAAD battery, costing roughly US$1 billion (approximately RM3.8 billion), underscores the economic dimension of missile defense architecture as well as the strategic cost of attrition.

Iran’s capacity to launch large-scale missile salvos, potentially numbering in the thousands over sustained conflict, introduces the risk that even layered defenses could be saturated if radar nodes are degraded or destroyed.

The broader implication is that the Middle East’s missile defense equilibrium rests on a limited number of high-value sensors vulnerable to precision strikes, making the “open secret” less a rumor and more a structural vulnerability within a contested strategic environment.

Defence Security Asia assesses that unless diplomatic channels meaningfully reduce escalation, the contest between radar-based missile defense and Iran’s expanding ballistic arsenal will remain a defining fault line in Gulf security architecture under renewed Trump-era confrontation. — DEFENCE SECURITY ASIA
