US Intelligence Warns Pakistan Could Develop ICBM — Islamabad Fires Back, Says India’s Agni-VI and SLBM Program Pose Global Strike Risk

(DEFENCE SECURITY ASIA) — The inclusion of Pakistan in the 2026 Annual Threat Assessment as a state potentially developing intercontinental ballistic missile capability has triggered a strategic dispute over global missile proliferation, exposing how long-range strike technologies are reshaping deterrence calculations beyond South Asia and into the broader nuclear balance involving the United States homeland.

The assessment, presented to Congress by US Director of National Intelligence Tulsi Gabbard, warned that Pakistan’s advancing solid-fuel missile technology could eventually enable systems capable of striking targets outside South Asia, a projection that elevates Islamabad into the same analytical category as Russia, China, North Korea, and Iran in long-range missile risk modelling.

Pakistan’s Foreign Office responded with an unusually forceful rebuttal, rejecting the characterisation as inaccurate while simultaneously redirecting scrutiny toward India’s expanding long-range missile inventory, arguing that New Delhi’s pursuit of systems exceeding 12,000 kilometres represents a trajectory with implications extending far beyond regional deterrence.

 

Spokesperson Tahir Hussain Andrabi stated that Pakistan’s strategic capabilities are exclusively defensive and anchored in credible minimum deterrence vis-à-vis India, while asserting that India’s long-range missile development reflects ambitions that could affect security dynamics across Eurasia, the Pacific, and potentially territories beyond the Indo-Pacific theatre.

The dispute emerges against the backdrop of the US intelligence projection that the number of missiles capable of threatening the American homeland could rise from more than 3,000 today to over 16,000 by 2035, reinforcing Washington’s concern that incremental technological advances in propulsion, guidance, and solid-fuel systems can rapidly alter global strike reach.

The intelligence warning reflects a broader shift in strategic threat modelling in which future missile capability trajectories, rather than currently deployed arsenals, increasingly determine how Washington evaluates potential risks to homeland missile defence architecture and long-range deterrence stability.

Within this analytical framework, even regional missile programmes are assessed through the lens of technological scalability, meaning that advances in solid-fuel propulsion, range extension, and mobile launch platforms can quickly transform a theatre-level deterrent into a system with intercontinental implications.

As a result, the confrontation between the US assessment and Pakistan’s rebuttal highlights a widening global debate over how emerging missile capabilities in South Asia intersect with the evolving strategic balance among nuclear-armed states, particularly as longer-range delivery systems blur the line between regional deterrence and global strike potential.

US Threat Assessment and the Expansion of Long-Range Missile Risk Modelling

The 2026 Annual Threat Assessment places Pakistan under heightened scrutiny by arguing that continued progress in missile propulsion, guidance, and solid-fuel engineering could allow future systems to extend well beyond the currently declared range of Pakistan’s longest known missile, the Shaheen-III, which reaches approximately 2,750 kilometres.

The report does not claim Pakistan currently fields an intercontinental ballistic missile, but it assesses that ongoing technological trends could provide the capability to develop weapons exceeding the 5,500-kilometre threshold typically associated with ICBM classification, thereby expanding potential strike envelopes beyond South Asia.

US intelligence concern is tied to the strategic logic that incremental improvements in range, payload integration, and fuel efficiency can shorten the timeline between regional deterrent systems and true intercontinental capability, particularly when combined with advances in indigenous solid-fuel manufacturing infrastructure.

The assessment also references past procurement patterns and sanctions actions targeting entities linked to missile technology development, suggesting that external supply networks and domestic production capacity together could accelerate the evolution of longer-range delivery systems.

By grouping Pakistan with states already possessing or pursuing intercontinental reach, the report signals that Washington’s threat modelling increasingly evaluates capability trajectories rather than currently deployed systems, a methodology that expands the number of countries considered relevant to homeland defence planning.

This analytical approach reflects a shift in US strategic warning frameworks toward forecasting future strike potential rather than reacting only to operational deployments, which in turn raises the political sensitivity of intelligence assessments for states whose programmes remain below intercontinental range.

The projection of a dramatic increase in potential missile threats to the United States homeland by 2035 further underscores the Pentagon’s concern that advances in propulsion and guidance technologies are spreading faster than traditional arms control mechanisms can regulate.

Within this framework, Pakistan’s missile programme becomes significant not because of its current range, but because technological pathways exist that could eventually enable systems capable of crossing continents if development continues without constraint.

The report’s language therefore reflects a preventive intelligence posture designed to identify emerging strategic risks early, even when the operational capability under discussion has not yet been demonstrated in flight testing.

This forward-looking assessment model is precisely what Islamabad disputes, arguing that its programme remains tied to regional deterrence requirements rather than any ambition to develop intercontinental strike capability.

Pakistan’s Rebuttal and the Doctrine of Credible Minimum Deterrence

Pakistan’s Foreign Office framed the US assessment as inconsistent with the declared doctrine of credible minimum deterrence, emphasising that its missile programme is designed to maintain strategic balance with India rather than to project power beyond South Asia.

Tahir Hussain Andrabi stated that Pakistan categorically rejects the assertion that its missile capabilities pose a potential threat to the United States, insisting that the programme remains below intercontinental range and is intended solely to safeguard national sovereignty and regional stability.

The response highlights how Pakistan’s deterrence posture is structured around maintaining survivable retaliatory capability against India, rather than pursuing global strike reach, which Islamabad argues would contradict its long-standing strategic doctrine.

By stressing the defensive nature of its arsenal, Pakistan seeks to counter the implication that technological progress automatically translates into offensive intent, a distinction that often becomes blurred in intelligence assessments focused on capability rather than declared policy.

Islamabad’s rebuttal also reflects concern that being grouped with major strategic competitors of the United States could carry diplomatic consequences, including increased sanctions risk, export controls, and heightened monitoring of dual-use technologies.

The statement therefore attempts to separate Pakistan’s missile development from the broader global missile proliferation narrative, portraying its programme as regionally bounded and driven by the specific requirements of deterrence against India.

At the same time, the response pivots to India’s missile programmes in order to argue that the true source of long-range escalation lies not in Islamabad’s capabilities but in New Delhi’s pursuit of systems with far greater reach.

This rhetorical shift demonstrates how missile development in South Asia is interpreted through a competitive lens, where each side frames the other’s advances as destabilising while presenting its own as necessary for balance.

Pakistan’s emphasis on India’s longer-range systems also reflects the reality that deterrence calculations are shaped not only by existing deployments but by the maximum potential reach of weapons under development.

The rebuttal therefore transforms a US intelligence warning into a regional strategic argument, redirecting attention from Pakistan’s trajectory to the broader implications of India’s expanding missile inventory.

Agni-V and the Expansion of India’s Long-Range Strike Envelope

Pakistan’s response specifically identifies India’s Agni-V ballistic missile as evidence that long-range strike capability already exists within South Asia, noting that the system’s range exceeding 5,000 kilometres places much of Asia within reach from Indian territory.

The Agni-V is road-mobile and canister-launched, a configuration that enhances survivability by allowing rapid deployment from dispersed locations while reducing preparation time compared to earlier liquid-fuel missile systems.

Its integration into India’s nuclear triad gives New Delhi a land-based component capable of delivering nuclear payloads at extended range, complementing air-delivered and sea-based deterrent forces in a structure designed to ensure second-strike capability.

Pakistan’s reference to Agni-V reflects concern that mobility, solid-fuel propulsion, and canisterisation together create a more flexible and survivable missile force, complicating adversary targeting and strengthening deterrence credibility.

The system’s operational status also distinguishes it from programmes still under development, meaning that India already possesses a long-range strike platform capable of reaching targets well beyond the immediate South Asian region.

Pakistan’s argument suggests that once such capability exists, further range expansion becomes a matter of technological refinement rather than strategic transformation, reinforcing its claim that India’s trajectory extends beyond regional deterrence.

The presence of a road-mobile intercontinental-class missile also has implications for early warning and missile defence planning, since mobility increases uncertainty about launch locations and reduces reaction time for defensive systems.

From Islamabad’s perspective, Agni-V demonstrates that the threshold between regional and global strike capability has already been crossed by India, even if official range figures remain below full intercontinental classification.

This interpretation feeds into Pakistan’s broader narrative that strategic imbalance is being driven by India’s technological progression rather than by its own missile programme.

As a result, the Agni-V becomes not only a weapons system but a symbol in the diplomatic contest over how missile developments in South Asia should be interpreted by global powers.

Agni-VI and the Prospect of True Intercontinental Reach

Pakistan’s rebuttal places particular emphasis on India’s Agni-VI programme, which defence analysts estimate could achieve a range of up to 12,000 kilometres once development is complete, a distance that would enable strikes across Eurasia and into the Pacific.

The missile is described as a multi-stage solid-fuel system under development, with design work completed and hardware phases ongoing, although it has not yet undergone flight testing or received full government approval for deployment.

If operationalised, such a range would move India from extended regional deterrence into the category of states capable of true intercontinental strike, significantly altering the scale at which its missile forces could influence global security calculations.

Pakistan argues that the pursuit of this capability raises concerns beyond South Asia because weapons with this reach inherently intersect with the strategic interests of other major powers, including Russia, Europe, and the United States.

The reference to Agni-VI therefore serves to challenge the logic of the US threat assessment by suggesting that India’s programme has clearer intercontinental implications than Pakistan’s current missile inventory.

From a strategic standpoint, the development of longer-range missiles also affects deterrence stability by expanding the number of potential targets and increasing the complexity of missile defence planning.

The possibility of multiple warhead integration, often associated with advanced ICBM designs, would further complicate interception by requiring defensive systems to track and engage several re-entry vehicles simultaneously.

Pakistan’s emphasis on Agni-VI reflects the belief that the introduction of true intercontinental capability by one regional power inevitably alters the strategic environment for all others.

This perspective reinforces Islamabad’s argument that its own missile development must be understood within the context of maintaining balance against a neighbour whose range ambitions extend far beyond the subcontinent.

As long as Agni-VI remains under development, its strategic impact is based on projected capability rather than deployed force, yet even projected reach can influence deterrence calculations and diplomatic positioning.

K-5 SLBM and the Strategic Implications of Sea-Based Deterrence

The third system highlighted by Pakistan is the K-5 submarine-launched ballistic missile, designed for deployment on India’s Arihant-class nuclear-powered submarines as part of the sea-based component of the nuclear triad.

With an estimated range between 5,000 and 8,000 kilometres depending on variant, the missile would allow launches from the Indian Ocean that could reach targets far beyond South Asia without requiring forward deployment of land-based systems.

Pakistan argues that the stealth characteristics of submarine patrols significantly expand the strategic footprint of such weapons, since sea-based platforms can approach closer to potential targets while remaining difficult to detect.

A missile launched from a submerged platform during extended ocean patrols could theoretically threaten regions including parts of Europe, Russia, Israel, or US territories in the Pacific, depending on patrol location and payload configuration.

This capability introduces a different level of strategic complexity because sea-based deterrence is designed to ensure survivability even after a first strike, making it a cornerstone of nuclear stability doctrines worldwide.

Pakistan’s critique suggests that once a state possesses long-range SLBM capability, its deterrent posture cannot be considered purely regional, since the mobility of submarines allows strike reach to shift dynamically.

The deployment of such systems during extended patrols also complicates intelligence monitoring, as tracking submarine movements requires persistent maritime surveillance rather than fixed-site observation.

From Islamabad’s perspective, the K-5 represents evidence that India’s strategic trajectory includes not only longer range but also more survivable delivery platforms, a combination that amplifies deterrence credibility.

The emphasis on submarine-launched missiles therefore reinforces Pakistan’s argument that global-range implications already exist within India’s arsenal, even before the introduction of future systems.

In this context, the dispute over the US threat assessment reflects a broader competition over how missile developments are interpreted, with each side seeking to shape international perception of which programme represents the greater strategic risk.
