I. Introduction

Israel won most of the major wars against neighboring Arab countries, including the 1948 Arab–Israeli War, the Six-Day War of 1967, and the Yom Kippur War of 1973. Moreover, Israel invaded Lebanon six times, including 1982, 2006 and 2026. Most surprisingly, Israel launched attacks to Iran in June 2025 and February 2026 and bombed Tehran and nuclear sites in Iran. Seth Frantzman, senior Middle East analyst for The Jerusalem Post, said that Israel’s military is now among the strongest in the Middle East and became a potential regional hegemonic power. [1]

As Table 1 shows, Israel appears to be stronger than Iran, even though Iran has a significantly larger population than Israel, with Iran at approximately 89 to 92.4 million people compared to Israel’s 9.4 to 10.1 million people.

In fact, according to the 2026 Global Firepower Index, Israel is the 15th strongest military power out of 145 countries in the world, surpassing Iran, which ranked 16th.

With this information, this paper analyzes what make the Israel Defense Forces (IDF) the strongest armed forces in the Middle East.

II. What is the IDF and how was it created?

The IDF is the national military of the State of Israel. As Figure 1 shows, the IDF consists of three service branches: the Israeli Ground Forces, the Israeli Air Force, and the Israeli Navy. It is the sole military wing of the Israeli security apparatus. The IDF is headed by the chief of the general staff, who is subordinate to the defense minister.

On the orders of first prime minister of Israel David Ben-Gurion, the IDF was formed on 26 May 1948 and began to operate as a conscript military, drawing its initial recruits from the already existing paramilitaries of the Yishuv – namely the Irgun, Haganah, and Lehi. It was formed shortly after the Israeli Declaration of Independence and has participated in every armed conflict involving Israel. [2]

Figure 1: Structure of IDF (source: Wikipedia)

In the wake of the 1979 Egypt–Israel Peace Treaty and the 1994 Israel–Jordan Peace Treaty, the IDF underwent a significant strategic realignment. Previously spread across various fronts – Lebanon and Syria in the north, Jordan and Iraq in the east, and Egypt in the south – the IDF redirected its focus towards southern Lebanon and the Palestinian territories. In 2000, the IDF withdrew from southern Lebanon and in 2005 from Gaza. Conflicts between Israel and Islamist groups based in Gaza, notably Hamas, has continued since then. Since the Hamas launched attacks on Israel on October 7, 2023, Israel has been at war with them, and more than 41,000 Palestinians in Gaza have been killed by the IDF. Moreover, the IDF invaded parts of southern Lebanon in March 2026 to dismantle Hezbollah’s military infrastructure, create a security buffer zone, and halt cross-border rocket and drone attacks.

Since 1967, the IDF has maintained a close security relationship with the US, including weapon research and development cooperations, with joint efforts on the F-15I and the Arrow Defense System, among others. The IDF is believed to have maintained an operational nuclear weapons capability since 1967, possibly possessing between 80 and 400 nuclear warheads. [3]

III. Sources of IDF’s superior military strength

1. Overview

Despite its relatively small population and limited geographic size, Israel has developed one of the world’s most capable and technologically sophisticated armed forces.

The IDF is considered the strongest military in the Middle East thanks to technological superiority, strong air forces and advanced missile defense systems, a strategic alliance with the US and nuclear deterrence, and a mandatory service system and a reserve force with extensive combat experiences.

The sources of the IDF‘s superior military power can be explained in the following three aspects:

a. Technology and equipment

• Strongest air force and air supremacy: Israel possesses the strongest air force in the Middle East by operating state-of-the-art aircrafts such as the US-made F-35 stealth fighter, F-15, and F-16, and holds air supremacy throughout the Middle East.
• Advanced Missile Defense System: Israel features a multi-layered defense network comprising the Iron Dome, David’s Sling, and the Arrow Systems.
• Domestic innovation: Israel manufactures its own advanced hardware, such as precision-guided weapons and electronic warfare systems.

b. Strategic alliance with the US and nuclear deterrence

• U.S. support: Israel receives substantial military aid, joint training, and cutting-edge defense equipment from the US.
• Strategic nuclear deterrence: Israel is the only country in the Middle East widely believed to possess nuclear weapons with an estimated stockpile of about 90 warheads.

c. Personnel and structure

• Experienced reservists: Israel has hundreds of thousands of combat-ready reservists with extensive combat experience who can be rapidly mobilized.
• Compulsory service: Israel maintains approximately 170,000 active-duty personnel through the compulsory service system.

2. Technology and equipment

A major reason behind the Israel military strength is the country’s heavy reliance on intelligence and advanced technology. Israel invests heavily in:

• Surveillance systems
• Cybersecurity capabilities
• Precision-guided weapons
• Unmanned aerial vehicles (UAVs)
• Electronic warfare
• Advanced radar networks
• Intelligence collection platforms

These technologies provide early warning of potential threats and help Israeli military leaders make faster and more informed decisions.

Intelligence gathering is considered one of the most important pillars of Israel’s national security strategy and plays a key role in maintaining operational effectiveness.

a. Air superiority with the strongest air forces in the Middle East

One of the defining features of the Israeli military strength is its overwhelming emphasis on air power.

As Figure 2 shows, the Israel Air Forces remain one of the most powerful, technologically advanced, and combat-proven air forces in the world. The Israeli Air Forces is ranked 9th globally ahead of France’s air forces in the World Directory of Modern Military Aircraft (WDMMA) 2026 report. Despite Israel’s relatively small geographic size, the Israeli Air Forces (IAF) serves as the cornerstone of the country’s national defense strategy and provides a decisive military advantage across the region.

Because Israel has limited geographic depth, maintaining control of the air is considered essential for its national security. Air superiority allows the country to detect threats early, respond rapidly, and project military power with precision.

For decades, Israel has invested heavily in air superiority, intelligence capabilities, precision strike systems, and advanced aviation technology. As a result, the Israeli Air Forces have developed a reputation for operational excellence, rapid response capability, and highly effective mission execution.

Its ability to conduct multiple mission types simultaneously makes it one of the most versatile air forces in the world.

As Table 3 shows, the Israel Air Forces operate 597 cutting-edge aircrafts, including American-made F-35 stealth fighters, F-15s, and F-16s.

• F-35I Lightning II: Israeli fifth-generation stealth jets forming core strike and regional deterrence squads, with plans expanding the fleet toward 100 units.
• F-15 (Eagle / Ra’am / IA): Israeli heavy multi-role and long-range strike platforms used for deep-penetration missions.
• F-16 (Fighting Falcon): Israeli backbone multi-role tactical fleet numbering over 170 active airframes.
• Support & Special Mission: the Israeli Air Forces operate heavy-lift helicopters such as the CH-53, tactical transport via C-130J, and specialized electronic intelligence (SIGINT)

b. Invincible missile defense system

Maintaining control of national airspace and protecting population centers from potential missile threats are considered essential defense priorities.

As Table 4 shows, one of the most important contributors to the Israel military strength is the country’s highly sophisticated and multi-layered missile defense network. Over several decades, Israel has developed one of the world’s most advanced defensive architectures, designed to protect the nation from a wide range of aerial threats.

As Israel faces a complex security environment threatened by various state and non-state armed groups, missile defense has become a core pillar of its national defense strategy. The Israeli missile defense system is designed to detect, track, and intercept threats at different ranges before they can reach civilian population centers, military bases, or critical infrastructure.

Table 4: Key Components of Israel’s Missile Defense Network (source: MilitaryCompare.com)

The multi-layered missile defense system, seen in Table 4, allows Israel to respond to multiple threats simultaneously while improving national resilience and deterrence. Together, these defense systems form one of the most advanced missile defense shields in the world and provide multiple layers of protection against evolving aerial threats.

i) Iron Dome

The Iron Dome is the first layer of Israel’s missile defense network, designed to intercept short-range rockets, artillery projectiles, and similar threats.

The Iron Dome uses advanced radar technology and real-time tracking software to determine whether or not an incoming projectile poses a threat to critical infrastructure or populated areas.

Key advantages of Iron Dome include:

• Rapid threat detection
• Precision interception capability
• Advanced radar systems
• Selective engagement technology

One of the Iron Dome system’s most notable features is its ability to engage only those threats that are assessed as dangerous, helping conserve interceptor resources. Because of its effectiveness and technological sophistication, the Iron Dome has become one of the most recognized missile defense systems in the world.

ii) David’s Sling

The David’s Sling system serves as the middle layer of Israel’s missile defense system. It was developed to address threats that fall between long-range ballistic missiles and short-range rockets.

The David’s Sling system is designed to counter:

• Tactical ballistic missiles
• Cruise missiles
• Advanced aerial threats
• Medium-range missile systems

David’s Sling greatly expands Israel’s defensive coverage and strengthens the country’s ability to respond to increasingly sophisticated missile technologies. By filling the gap between Iron Dome and the Arrow System, David’s Sling creates a more complete and flexible defensive network.

iii) Arrow Missile Defense System

The Arrow Missile Defense System represents the highest layer of Israel’s missile shield, specifically designed to counter long-range ballistic missile threats.

This defense system focuses on intercepting incoming missiles before they can reach their intended targets, providing strategic-level protection for the country.

Key capabilities of the Arrow Missile Defense System include:

• Long-range threat interception
• Ballistic missile defense
• Advanced tracking technology
• Strategic deterrence support

The Arrow Defense System is considered one of the most advanced ballistic missile defense programs in the world and plays a central role in Israel’s national security strategy.

Overall, Israeli multi-layered missile defense systems work together to enhance national security and strengthen the country’s overall deterrence capability.

c. Domestic innovation

Israel defense industry produces its own advanced hardware, such as precision-guided weapons and electronic warfare systems. One of the greatest advantages behind the Israel military strength is its highly advanced domestic defense industry. Unlike many countries that depend heavily on foreign military suppliers, Israel designs, develops, and manufactures a significant portion of its own military equipment and defense technologies.

This self-reliance provides the Israel military with greater flexibility, faster innovation, and the ability to adapt quickly to evolving security threats.

The Israel defense industry supports the development of:

• Missile defense systems
• Unmanned aerial vehicles (UAVs)
• Military electronics
• Radar systems
• Communication technologies
• Precision-guided weapons

This strong industrial base plays a critical role in maintaining the technological edge that defines the Israel military strength.

Several world-class Israeli defense companies form the backbone of the Israel defense industry. These defense companies develop many of the advanced technologies used by the IDF and exported to military customers worldwide. Israel’s defense industry is dominated by three major companies: Israel Aerospace Industries (IAI), Rafael Advanced Defense Systems, and Elbit Systems. These three firms rank among the world’s top 34 defense contractors. [4]

i) Israel Aerospace Industries (IAI)

IAI is one of the most important contributors to the Israel military strength. This company specializes in:

• Missile systems
• Aerospace technologies
• Radar solutions
• Surveillance platforms

IAI plays a major role in strengthening Israel’s air power, intelligence capabilities, and advanced defense technologies.

ii) Rafael Advanced Defense Systems

Rafael Advanced Defense Systems is internationally recognized for developing some of Israel’s most advanced military technologies. This company is known for:

• Missile defense systems
• Advanced defense technologies
• Precision-guided weapons
• Air defense solutions

iii) Elbit Systems

Elbit Systems is another major contributor to the Israel military strength. This company develops:

• Communication systems
• Military electronics
• Battlefield management platforms
• Surveillance technologies
• Defense software solutions

Elbit’s technologies help improve command-and-control capabilities, military communications, and battlefield awareness.

3. Strategic alliance with the US and nuclear deterrence

a. Strategic Alliance with the US

By building a strategic alliance with the US, Israel has received substantial military aid, joint training, and cutting-edge defense equipment from the US.

Maintaining Israel’s regional military hegemony is a core element of the US’ Middle East policy. This has been achieved by US funding and an increasing Israeli military arsenal. [5]

For example, Israel’s Iron Dome system was developed in 2006 and came into operation in 2011. The Iron Dome was created with the help of the US, which is responsible for supplying parts for the system, including setting aside more than $1.5bn in missile defense for Israel in 2022.

As Figure 3 shows, Israel is the largest recipient of US foreign aid, having received some $300bn between 1946 and 2024. [6] This is almost double (1.7 times more) than the second-highest recipient of US foreign aid, Egypt, which received $151.9bn in the past 77 years.

Figure 3: Israel is the largest cumulative recipient of US Aid since 1946 (source: US Congressional Research Service and CFR)

The US provided Israel with considerable economic assistance from 1971 to 2007, but nearly all US aid today goes to support Israel’s military. The US has provisionally agreed via a memorandum of understanding (MOU) in 2016 to provide Israel with $3.8 billion per year through 2028, including $500 million per year for missile defense.

As Figure 4 and 5 show, US military aid to Israel has greatly increased after the 1970s, in particular the 1973 War. U.S. military aid reportedly accounted for around 20 percent of Israel’s defense budget in the years prior to the 2023 Israel-Hamas War.

Figure 4: US military aid to Israel (source: US Congressional Research Service)

Figure 5: The US has provided significant military aid to Israel since the 1970s (source: US Congressional Research Service and CFR)

In particular, since the start of Israel’s war with Hamas on October 7, 2023, the US has enacted legislation providing at least $16.3 billion in direct military aid to Israel. The aid was authorized in three pieces of legislation: a supplemental appropriations act in April 2024 which provided $8.7 billion, and appropriations acts in 2024 and 2025 which provided $3.8 billion per year in line with the MOU. Of the total, $6.7 billion is for missile defense.

Moreover, as Figure 6 shows, Israel has historically been one of the top recipients of U.S. arms sales. In April 2025, Israel had 751 active FMS cases with the US, worth a total of roughly $39 billion. Israel has also been permitted to use a portion of its FMF aid to buy equipment from Israeli defense companies – a benefit not granted to other recipients of US military aid, which are required to buy from US defense firms. However, this domestic procurement benefit is set to be phased out in the next few years.

Figure 6: Israel has been a top recipient of U.S. arms sales (source: US Department of Defense and CFR)

As Figure 7 shows, while Israel purchases some arms from other countries, the large majority of its arms imports come from the US. In recent years, the remainder have come mainly from Germany, although in August 2025, the German government announced that it would not provide military equipment that could be used in Gaza.

Figure 7: How Israel’s imports of US arms stack up (source: SIPRI and CFR)

Furthermore, Israel has been using American-made weapons against its enemies – including Iran, Hamas and Hezbollah – for decades. The Israeli military has reportedly received expedited deliveries of weapons from a strategic stockpile that the US has maintained in Israel since the 1980s.

In May 2025, the Israeli Defense Ministry said that since October 2023, the US had delivered ninety thousand tons of arms and equipment on eight hundred transport planes and 140 ships. The extraordinary flow of aid has included tank and artillery ammunition, rockets, bombs, and small arms.

In addition, the US and Israel have collaborated on the research, development, and production of defense systems used by Israel, including the Iron Dome, David’s Sling, Arrow, Arrow II, Arrow III, and Iron Beam. The US has been a production partner of the Iron Dome with Israel since 2014. David’s Sling and the Arrow system were developed jointly by the US and Israel. Iron Beam development was begun by an Israeli company, with the US defense company Lockheed Martin later joining development.

b. Strategic nuclear deterrence

Israel is the only country in the Middle East widely believed to possess nuclear weapons with an estimated stockpile of around 90 warheads. [7]

This posture shapes Israel’s security in three primary ways:

• Deliberate ambiguity: Israel maintains a policy of nuclear ambiguity. It neither confirms nor denies possessing nuclear weapons, which allows the country to deter attacks while avoiding the regional arms race and international pressures that a formal declaration may trigger.
• Ultimate insurance: The perceived arsenal – estimated by experts to be about 90 warheads – ensures that even if Israel’s conventional military forces were to be overwhelmed by a coalition of hostile Arab neighboring countries, the state itself cannot be fully eradicated without an unacceptable cost to the attacker.
• Preemption: Because Israel views a hostile nuclear-armed neighbor as an existential threat, this status has driven a doctrine where it actively prevents adversaries from acquiring similar nuclear capabilities. This was demonstrated by historical preemptive strikes on nuclear reactors in Iraq (1981) and Syria (2007), and recent bombing on Iran’s nuclear sites (2026) to prevent Iran from developing a nuclear weapon.

4. Personnel and structure

The Israel military strength benefits greatly from its manpower structure, particularly its large reserve component. Israel maintains a core of roughly 170,000 active-duty personnel alongside hundreds of thousands of combat-ready reservists who can mobilize rapidly.

For a country like Israel with limited geographic depth and a relatively small population, rapid mobilization is essential. The ability to activate hundreds of thousands of trained reservists within a short period provides Israel with a significant strategic advantage and strengthens overall deterrence.

With approximately 465,000 reserve personnel, Israel maintains a reserve force that is nearly three times larger than its active-duty military. This reserve system provides several strategic benefits for Israel:

• Large pool of trained personnel
• Rapid military expansion during emergencies
• Enhanced national defense readiness
• Greater operational flexibility
• Long-term force sustainability

Because many reservists have prior military training and experience, they can be integrated into military operations much faster than newly recruited personnel. In addition, the Israel military strength benefits from its mandatory service system. Israel’s security environment requires a military capable of responding quickly to a wide range of external threats.

Mandatory military service system helps support this goal by:

• Building a trained manpower base
• Strengthening reserve force capability
• Supporting national mobilization plans
• Maintaining military readiness
• Enhancing defense resilience

The combination of mandatory military service system, extensive reserve forces, and rapid mobilization capability allows Israel to maintain a level of military readiness that far exceeds what its population size alone may suggest.
