How Iran Built Its Military and Weapons Over Decades of Conflict
Nearly five decades of war, sanctions, and adaptation shaped Iran’s modern offensive capabilities
Six weeks of US and Israeli bombardment have significantly damaged Iran’s nuclear infrastructure and weakened parts of its armed forces, but the country’s offensive capabilities (توانمندی‌های تهاجمی) [tavānamandi-hā-ye tahājomi] are the result of nearly 50 years of continuous development. Throughout this period, Iran has either been directly involved in war or faced the persistent threat of conflict, shaping a military doctrine focused on resilience and deterrence. Understanding this evolution is essential to grasp the dynamics of the ongoing conflict and the implications of military strategy adaptation (تطبیق راهبرد نظامی) [tatbiq-e rāhbord-e nezāmi].
Before the establishment of the Islamic Republic in 1979, Iran relied heavily on Western suppliers, particularly the United States, for its military equipment. By the time the Iran-Iraq war began in 1980, Iran possessed a large arsenal that included advanced fighter aircraft and thousands of tanks, reflecting a period of strong defense procurement (تأمین تجهیزات دفاعی) [ta'min-e tajhizāt-e defā'i]. However, the prolonged war exhausted these resources, and the country’s growing international isolation made replenishment increasingly difficult.
Following the war’s end in 1988, Iran faced severe economic and political constraints. Although it acquired some equipment from the Soviet Union and China in the early 1990s, its limited financial capacity restricted large-scale military expansion. At the same time, international sanctions and arms embargoes forced Iran to develop domestic arms production (تولید داخلی تسلیحات) [tolid-e dākheli-ye taslihāt], a turning point that led to greater self-reliance in defense manufacturing.
Much of Iran’s modern military hardware is based on reverse-engineered versions of older American and Soviet systems. Despite this, the country has made notable progress in missile technology since the 1990s, supported by both domestic innovation and external expertise. This advancement in ballistic missile development (توسعه موشک‌های بالستیک) [tose'e-ye moshak-hā-ye bālistik] has become a cornerstone of Iran’s deterrence strategy, enabling it to project power across the region.
In parallel, Iran pioneered the use of one-way attack drones, offering a cost-effective method to strike distant targets. These systems have become a key component of modern warfare, illustrating Iran’s emphasis on asymmetric warfare tactics (تاکتیک‌های جنگ نامتقارن) [taktik-hā-ye jang-e nāmotaghāren], which aim to offset conventional military disadvantages by leveraging innovation and strategic flexibility.
The structure of Iran’s military reflects its dual approach to defense and power projection. The regular army, known as the Artesh, focuses primarily on territorial defense, while the Islamic Revolutionary Guard Corps serves as the main force for regional operations. The Guard, particularly its Quds Force, plays a central role in proxy warfare operations (عملیات جنگ نیابتی) [amaliyāt-e jang-e niyābati], supporting allied groups and influencing conflicts across the Middle East.
Iran has long backed organizations such as Hezbollah in Lebanon and, more recently, provided support to Hamas in Gaza. These relationships demonstrate a strategic effort to extend influence without direct confrontation, reinforcing a model of regional power projection (اعمال قدرت منطقه‌ای) [e'māl-e ghodrat-e manteqei]. This approach allows Iran to engage adversaries indirectly while minimizing the risk of large-scale retaliation.
In addition to conventional and proxy strategies, Iran has invested heavily in cyber capabilities. Cyber operations offer a relatively low-cost means of exerting influence, enabling attacks on military, governmental, and infrastructure targets. Iranian-linked hackers have targeted networks and facilities, highlighting the growing importance of cyber warfare capabilities (توانمندی‌های جنگ سایبری) [tavānamandi-hā-ye jang-e sāybari] in modern conflict.
Iran’s pursuit of nuclear capabilities has been another defining element of its military development. While Iranian authorities maintain that their nuclear program is intended for civilian energy production, evidence of advanced uranium enrichment has raised concerns internationally. This tension has made nuclear proliferation concerns (نگرانی‌های گسترش هسته‌ای) [negarāni-hā-ye gostarsh-e haste'i] a central issue in global diplomacy.
Efforts to limit Iran’s nuclear progress have included both diplomatic agreements and covert operations. The discovery of the Stuxnet malware in 2010 marked a significant moment in cyber warfare, as it disrupted Iran’s nuclear centrifuges. Later, the 2015 nuclear agreement led to temporary restrictions on enrichment activities in exchange for sanctions relief, reflecting attempts at multilateral negotiation frameworks (چارچوب‌های مذاکره چندجانبه) [chārchub-hā-ye mozākere-ye chandjānebeh].
However, after the United States withdrew from the agreement in 2018, Iran gradually resumed its nuclear activities. By 2020, enrichment efforts had restarted, alongside increased production of missiles and drones. These developments illustrate the fragility of diplomatic arrangements and the persistence of strategic deterrence policies (سیاست‌های بازدارندگی راهبردی) [siāsat-hā-ye bāzdārandeghi-ye rāhbordi] in shaping national defense priorities.
The current phase of the conflict has seen extensive use of missiles and drones. Prior to the escalation, analysts estimated that Iran possessed thousands of ballistic missiles and a vast stockpile of drones. In the early weeks of fighting, hundreds of these weapons were deployed, underscoring the scale of Iran’s missile strike capacity (ظرفیت حملات موشکی) [zarfiyat-e hamalāt-e moshaki].
Despite sustained attacks on its military infrastructure, Iran continues to launch missiles, though at a reduced rate. This persistence suggests that significant reserves may still exist, even as production and logistics capabilities have been damaged. The ongoing exchange of missile and interceptor systems highlights the evolving nature of aerial defense systems (سامانه‌های دفاع هوایی) [sāmāneh-hā-ye defā-e havāyi] in modern warfare.
