Nournews: The entry of the aircraft carrier George H.W. Bush into the Arabian Sea within CENTCOM’s area of responsibility, when viewed in the context of recent months’ developments, can no longer be considered a normal deployment. The move in fact continues a trajectory that emerged after the end of the 40-day conflict—a trajectory in which Washington seeks to achieve through incremental and structural pressure objectives it failed to secure on the battlefield and could not impose on Iran in negotiations such as those held in Islamabad.
Within this framework, increasing emphasis on a naval blockade is not a short-term tactical measure, but part of a broader strategic doctrine based on the assumption of U.S. maritime superiority. This assumption rests on the idea that control over shipping lanes can be turned into an effective lever to compel Iran to alter its behavior.
Prediction before the conflict
Several months prior to the outbreak of hostilities, the late Admiral Ali Shamkhani, in an interview with Javad Moghimi, explicitly stated: “No attack can eliminate Iran’s response capability, and there are capacities that have not yet been activated.”
The significance of this statement lies not in its wording, but in the position of its author—a figure who previously commanded the joint naval forces of the Army and the Islamic Revolutionary Guard Corps (IRGC), later served as Minister of Defense contributing to the development of military industrial and technological infrastructure, and ultimately played a senior role in national security policymaking.
In other words, the remarks reflect an accumulated strategic understanding of both domestic capabilities and adversary limitations. When such an assessment is made prior to conflict and later finds tangible reflection in the field, it cannot be reduced to a mere personal analysis or media commentary.
Geography as a determining factor
To understand this assessment in practical terms, one must consider geography: the Persian Gulf and the Strait of Hormuz, one of the world’s most critical energy chokepoints. With an average depth of 30 to 40 meters and a narrow width, the Strait creates an operational environment in which the traditional advantages of large naval fleets are significantly reduced. Maneuverability is limited, reaction time is shorter, and the likelihood of surprise increases.
In such conditions, the compatibility between tools and battlefield becomes decisive. It is here that Iran’s strategy moves from general principles to concrete operational components.
Case 1: Small submarines, significant impact
One clear example is Iran’s small submarines. With a displacement of around 117 tons and limited crew size, these platforms are designed for shallow-water operations. A key feature is their ability to shut down engines completely and rest on the seabed, making detection by conventional sonar systems extremely difficult.
However, their importance is not limited to stealth. It lies in the ability to shift the timing and location of engagement. In a theater where large vessels are constrained to fixed routes, a hidden submarine can select the point of engagement—effectively transferring initiative from the stronger force to the weaker one, a central principle of asymmetric warfare.
Economically, these platforms are part of a broader equation: their production and maintenance costs are relatively low, while the potential threats they pose can affect assets worth billions of dollars.
Case 2: “Hoot” torpedo and changing engagement rules
Alongside platforms, weapon systems also play a decisive role. The “Hoot” torpedo, based on cavitation technology, is among the most notable examples. It travels within a gas bubble, reducing direct contact with water, resulting in extremely high speed and a distinct acoustic signature.
In operational terms, this leads to:
A significant reduction in target reaction time
Increased difficulty in interception and defense
Reports suggest that the system has been further optimized and localized in Iran, and when combined with small submarines, has become part of operational doctrine. In such a configuration, even a single successful strike may have consequences far beyond its initial cost.
Case 3: Naval mines and disruption economics
Another component of this strategy is the use of naval mines. In an environment such as the Strait of Hormuz, even a limited number of mines can cause major disruptions in maritime traffic. The key factor is not only physical damage, but also the psychological and economic impact: rising risk premiums, route diversions, and increased pressure on energy markets.
This tool becomes particularly significant in a blockade scenario, as the party enforcing the blockade must itself operate within a compromised security environment.
Case 4: Naval cruise missiles
In addition to sub-surface capabilities, naval cruise missiles form another layer of this operational framework. With ranges of several hundred kilometers, these systems are capable of striking maritime targets from safe distances, adding an additional dimension to deterrence and ensuring that threats are not limited to underwater domains.
Case 5: Fast missile boats
The role of fast missile boats cannot be overlooked. Due to their speed, numbers, and operational dispersion, they have become a constant feature of the maritime theater. Contrary to claims made by Donald Trump regarding the destruction of Iran’s navy, satellite imagery and field data indicate that hundreds of such vessels continue daily operations in the Persian Gulf and the Sea of Oman.
Some of these boats are equipped with anti-ship missiles and, through swarm tactics, can pressure the defensive systems of larger vessels. The combination of speed, agility, and numbers enables saturation attacks, significantly reducing the operational freedom of large warships in constrained environments such as the Strait of Hormuz.
Convergence of capabilities: formation of a doctrine
What is significant is not each system individually, but their integration. Small submarines, high-speed torpedoes, naval mines, and cruise missiles together form a multi-layered network aimed at increasing costs and reducing certainty for the opposing side.
Within such a network:
Full detection of threats becomes difficult
Neutralizing all risks is nearly impossible
Every action is accompanied by uncertainty
This approach can be described as deterrence through battlefield complexity.
Return to the aircraft carrier
Within this framework, the presence of the George H.W. Bush aircraft carrier gains a more precise meaning. As a symbol of classical U.S. military power, its deployment in such an environment simultaneously presents both opportunity and constraint. While it enables force projection and operational support, it also requires extensive protective layers for its own security.
In effect, a portion of its capability is dedicated to survival rather than operations—one of the key pressure points targeted by asymmetric strategies.
Naval blockade: tool or trap?
From this perspective, the concept of a naval blockade can be reassessed more precisely. Successful implementation requires sustained control, high security, and manageable costs. However, in a multi-layered threat environment, each of these conditions faces serious challenges.
A blockade may therefore function both as a pressure tool and as a cost trap—a situation in which maintaining control demands increasing resources, while the opposing side challenges that control with comparatively low-cost instruments.
In his interview conducted months before the conflict, Admiral Ali Shamkhani explicitly stated that Iran’s response capability is non-eliminable and that certain capacities remain unused. This reflects the principle of strategic ambiguity, aimed at preserving portions of capability in an undefined state to increase uncertainty in adversary calculations.
Developments following that interview indicate that these assessments were not merely theoretical. During the 40-day conflict, signs of this approach’s effectiveness became evident, while indications also suggest that not all capabilities have yet been deployed.
In such an equation, Iran’s visible and latent capabilities become variables capable of influencing strategic decision-making and introducing significant uncertainty into calculations based on conventional military superiority.
