August 22, National Defense Industry Day, is more than a date on the national calendar. It symbolizes the historic path Iran has taken to build its own security amid war, sanctions and restrictions. The day was added to Iran’s official calendar in 2010 at the proposal of the Minister of Defense and Armed Forces Logistics, with the approval of the Commander-in-Chief of the Armed Forces and the General Council of Culture. It was intended to commemorate an experience in which dependence on external sources gave way to confidence in Iran’s own capabilities.

Iran’s defense industry today is the product of decades of accumulated knowledge, experience and innovation by specialists who pursued self-sufficiency across land, naval, aerospace, missile and air-defense fields. But this path did not take shape overnight. Among the figures who played an influential role in it, the late Admiral Ali Shamkhani holds a special place. After the years of the Sacred Defense, as defense minister, he shifted his focus from managing the armed forces’ immediate needs toward creating sustainable capacity to generate defense power.

Shamkhani: From Battlefield Experience to the Architecture of Defense Self-Sufficiency

Shamkhani’s tenure at the Defense Ministry was a critical period in laying the foundations for, and accelerating, the country’s defense self-sufficiency. Official accounts of the period point to the beginning of a new phase in the development of military industries and the missile program’s transition toward extensive design, production and development.

Shamkhani’s role was not limited to pursuing the production of one or several military systems. His vision was that the defense industry should evolve from a collection of equipment manufacturers into a technological ecosystem, one that would connect the needs of the armed forces with up-to-date technology and narrow the gap between the battlefield, universities, research centers and industry. He also emphasized the need to remove obstacles to cooperation between research and defense sectors and viewed defense development as fundamentally technology-driven.

His approach to the defense industries, producing according to actual needs while employing advanced and sophisticated technologies, reflected a deliberate and forward-looking development of the defense sector. Combined with his command experience during the Sacred Defense, this approach helped create the foundation for turning the lessons of war into a more coherent program for building defense power.

Self-Reliance: A Response to the Logic of Sanctions

Iran’s defense industry developed during years when sanctions and restrictions made access to many foreign military systems and technologies difficult. Yet these very pressures became a catalyst for expanding domestic capabilities. Iran’s experience demonstrated that security built on knowledge, specialized human resources and domestic infrastructure is more resilient in the face of external pressure.

This was the path pursued by Shamkhani and other defense officials and commanders over different periods, drawing on the guidance of the great architect of the Islamic Revolution, Imam Khomeini, and continuing under the wise leadership of the Leader of the Revolution, the late Ayatollah Ali Khamenei: turning a defense requirement into a technological challenge, a technological challenge into an industrial project, and an industrial project into a deterrent capability. The result was the gradual expansion of missile, electronic, aerospace, naval and other defense capabilities.

Power on the Battlefield: Security Put to the Test

Indigenizing national security acquires strategic value when it goes beyond factories and laboratories and demonstrates its effectiveness on the battlefield. Recent wars, including the 12-Day War and the Ramadan War, once again underscored the importance of possessing independent defense capabilities and reducing vulnerabilities arising from foreign dependence.

Under such circumstances, defense power does not simply mean an accumulation of weapons. It encompasses knowledge, production, command, support, deterrence and the ability to make independent decisions. This capacity allows Iran to define its security on the basis of national will and gives it more options when faced with pressure to accept imposed arrangements.

The Strait of Hormuz also occupies a special place in this equation. Iran’s geographic position, combined with its naval capabilities and defense deterrence, has made the country a decisive actor in the security of the waterway. This demonstrates how defense power can become an element of national and regional power.

From Defense Power to Independent Diplomacy

Defense strength demonstrates its true importance when it also contributes to political independence in decision-making. A country that has not outsourced its security to foreign powers has greater capacity to defend its national interests when shaping its foreign relations.

The development of Iran’s defense industry has also created a foundation for expanding defense diplomacy, from security and military cooperation with regional countries to participation in joint military exercises and multilateral mechanisms. Domestic production capabilities have transformed Iran from a consumer of military equipment into an actor capable of playing a role in defense cooperation, technology and even the arms market.

In this context, Shamkhani’s managerial legacy can be summed up in one principle: sustainable security takes shape when a country’s defense needs are connected to domestic knowledge, national industry and an independent will. This approach continues today across a broad range of the country’s defense capabilities and forms part of the foundation of Iran’s national power.

Pressure and war were supposed to turn Iran into a “lesson for others.” But the experience of defense self-sufficiency produced a different story. A country that once depended on foreign sources to meet many of its defense needs now produces a significant part of its defense capabilities domestically. From this perspective, August 22 is not merely National Defense Industry Day; it is a day to commemorate the determination that demonstrated how independence, when combined with knowledge and strategic management, can move beyond a slogan and become real and enduring power.
