“This historic agreement strengthens our partnership and creates thousands of American jobs while securing the Gulf region.” — President Donald Trump, May 2025
In May 2025, the United States and Saudi Arabia signed a landmark $142 billion arms agreement during President Donald Trump’s official visit to Riyadh. Described as the largest arms deal in modern history, this transaction marks a transformative moment in US-Saudi strategic relations and Middle East security architecture.
The deal aims to deter Iranian threats in the Gulf while simultaneously boosting America’s defence manufacturing sector. It includes advanced air-to-air missiles, radar systems, wargaming technologies, logistical support, and commercial exports—representing a comprehensive military modernization package for the Kingdom under its Vision 2030 reforms.
📜 Why This Arms Deal Is Historic
The $142 billion US-Saudi arms pact represents far more than a defence transaction—it’s a strategic signal of recalibrated US foreign policy under President Trump’s second term. This agreement reflects a deliberate integration of economic diplomacy, defence exports, and regional influence.
Set against rising tensions with Iran, the deal serves as a cornerstone of Gulf security policy and underscores Washington’s long-term commitment to Middle Eastern allies. The magnitude of the agreement highlights Trump’s broader ambition to merge military strength with trade expansion and domestic job creation.
Think of this arms deal as a “security insurance policy” combined with an economic stimulus package. Saudi Arabia gets the military equipment to defend itself against regional threats (especially Iran), while the US gets billions in defence contracts that create American jobs—a win-win that strengthens the alliance without deploying US troops.
Historical Context:
- Builds on decades of US-Saudi military cooperation dating back to 1945
- Follows Trump’s previous $110 billion arms package announced in 2017 (first term)
- Reflects shift from direct US military intervention to “partner empowerment” strategy
- Aligns with Saudi Arabia’s Vision 2030 military modernization goals
- Comes amid heightened Iran-Gulf tensions and regional proxy conflicts
💰 Deal Highlights: What the $142 Billion Covers
The defence package includes a comprehensive array of advanced weaponry, support services, and commercial exports designed to transform Saudi Arabia’s military capabilities across multiple domains.
Key Components:
- Advanced Air-to-Air Missiles: Over 1,000 AIM-120C-8 medium-range missiles produced by RTX Corporation, valued at $3.3 billion
- Radar & Guidance Systems: Cutting-edge radar and targeting systems for enhanced aerial and ground combat precision
- Wargaming and Tactical Systems: Digital infrastructure and simulation technologies for strategic and operational planning
- Logistical & Maintenance Support: Multi-year contracts for training, parts supply, and system integration
- Commercial Exports: High-end gas turbines and dual-use technologies that complement military capabilities
AIM-120C-8 Missiles: These are advanced medium-range air-to-air missiles manufactured by RTX Corporation. The $3.3 billion missile component represents the largest single-item purchase in the broader $142 billion package.
This comprehensive bundle reflects a multi-domain investment spanning:
- Air Domain: Fighter jet capabilities, air defence systems
- Electronic Warfare: Radar, targeting, C4ISR (Command, Control, Communications, Computers, Intelligence, Surveillance, Reconnaissance)
- Logistical Support: Training infrastructure, maintenance, spare parts
- Commercial Integration: Dual-use technologies bridging military and civilian applications
🎯 Strategic Goals of the Agreement
The arms deal serves multiple strategic objectives for both the United States and Saudi Arabia, creating a complex web of military, economic, and diplomatic benefits.
1. Boosting Saudi Arabia’s Military Infrastructure
The deal enables Saudi Arabia to leapfrog into the ranks of top-tier global militaries. With ongoing conflicts in Yemen and border tensions, the Kingdom requires cutting-edge systems to maintain national security:
- Significant upgrades in air defence and missile interception capabilities
- Enhanced battlefield coordination via modern C4ISR systems
- Support for domestic military production under Vision 2030 reforms
- Improved deterrence against drone and missile threats
2. Strengthening Bilateral Relations
This arms deal signals a renewed era of US-Saudi trust and strategic alignment:
- Reaffirms Saudi Arabia as one of America’s most vital regional allies
- Demonstrates shared commitment to Iran deterrence and Gulf security
- Builds foundation for future defence and trade agreements
- Showcases Trump’s military diplomacy approach for strategic influence
3. Stimulating the US Defence Economy
The agreement delivers major economic benefits to American defence contractors and workers:
- Job Creation: Tens of thousands of manufacturing, logistics, and technology jobs
- Export Boost: Increased exports of US-made defence systems and technologies
- Long-term Contracts: Multi-year supply chain benefits across multiple states
- Industry Growth: Major wins for RTX Corporation, Lockheed Martin, and other contractors
This aligns with Trump’s “America First” economic policy by enhancing domestic industry through international agreements.
4. Securing the Gulf and Containing Iran
At its core, the deal is a direct counterbalance to Iran’s growing regional influence:
- Deters missile and drone threats from Iranian proxies (Houthis, Hezbollah)
- Strengthens naval and aerial surveillance in contested zones (Strait of Hormuz)
- Supports coalition-based regional defence initiatives
- Bolsters regional deterrence without deploying additional US forces
Does arming regional allies actually reduce US military involvement, or does it risk escalating arms races and proxy conflicts? While the deal avoids direct US troop deployment, it could intensify regional militarization and potentially draw America deeper into Gulf security dynamics if Saudi Arabia uses these weapons in controversial conflicts.
| Strategic Objective | US Benefits | Saudi Benefits |
|---|---|---|
| Military Capability | Reduces need for direct intervention | Modern defence systems, deterrence capacity |
| Economic Impact | Jobs, exports, defence industry growth | Technology transfer, Vision 2030 alignment |
| Regional Security | Stable Gulf, protected oil routes | Iran deterrence, border security |
| Strategic Alliance | Reliable Middle East partner | US security guarantee, diplomatic backing |
👥 Key Stakeholders and Corporate Involvement
President Donald Trump
In his second presidential term, Trump continues emphasizing an economic-first foreign policy where arms deals function as tools for diplomacy and industrial stimulus. This agreement reflects his administration’s aggressive defence export strategy and “America First” economic doctrine.
Crown Prince Mohammed bin Salman (MBS)
As the architect of Saudi Arabia’s Vision 2030, the Crown Prince is simultaneously modernizing the Kingdom’s military and economy. This deal aligns perfectly with his push for strategic autonomy, regional leadership, and domestic defence manufacturing capabilities.
RTX Corporation
A centerpiece of the agreement, RTX (formerly Raytheon Technologies) is supplying the 1,000+ AIM-120C-8 missiles and several advanced targeting systems. Headquartered in Tucson, Arizona, RTX stands to gain significantly in revenue and global defence partnerships. The company’s involvement spans:
- Missile manufacturing and delivery
- Radar and guidance system integration
- Long-term maintenance and support contracts
- Technology transfer and training programs
Defence Security Cooperation Agency (DSCA)
This federal agency coordinates all foreign arms sales, ensuring compliance with US national security interests and legal requirements. DSCA plays a pivotal role in:
- Approving foreign military sales (FMS)
- Conducting security assessments and end-use monitoring
- Aligning exports with US strategic objectives
- Managing Congressional notification processes
Don’t confuse: DSCA (Defence Security Cooperation Agency) with DARPA (Defence Advanced Research Projects Agency). DSCA manages foreign military sales and arms exports, while DARPA focuses on breakthrough military technology research and development.
🌍 Implications for Regional Security and US Foreign Policy
This arms deal represents a strategic recalibration of US foreign policy in the Middle East with far-reaching implications for regional security dynamics, alliance structures, and great power competition.
Regional Deterrence Enhancement:
Saudi Arabia’s bolstered capabilities serve as a direct deterrent to Iranian aggression across multiple threat vectors:
- Drone Warfare: Counter Iranian and proxy drone attacks on Saudi infrastructure
- Missile Threats: Intercept ballistic and cruise missiles from Yemen, Lebanon, Iraq
- Proxy Conflicts: Enhanced capacity in Yemen, Syria, Iraq theatres
- Maritime Security: Protect shipping lanes through Strait of Hormuz and Red Sea
Shift in US Strategy: From Deployment to Empowerment
The deal reflects a fundamental transformation in American Middle East policy:
- Burden Sharing: Regional allies assume primary security responsibilities
- Reduced Footprint: Less reliance on US troop deployments and bases
- Cost Effectiveness: Arms sales generate revenue while providing security
- Strategic Flexibility: US maintains influence without direct military commitments
Rather than deploying troops, the US equips allies with deterrent capabilities, enabling regional players to manage threats autonomously while preserving American geopolitical influence.
Industrial Diplomacy:
The agreement exemplifies a new paradigm where diplomacy is executed through economic instruments:
- Defence contracts as diplomatic currency
- Technology collaboration as trust-building mechanism
- Commercial integration reinforcing security partnerships
- Long-term industrial ties creating structural interdependence
Does the “partner empowerment” strategy actually reduce US involvement in Middle East conflicts, or does it simply change the nature of involvement from direct military action to indirect support through arms sales? Consider the ethical implications of arming authoritarian regimes, the risk of weapons proliferation, and whether this approach genuinely promotes regional stability or merely postpones direct US engagement.
