Five facts about where U.S. weapons go, how the sales process works and the benefits and risks involved

The United States sells more major weapons than any other country in the world. These transfers help arm allies, shape military partnerships and advance American foreign-policy goals—but they also raise difficult questions about oversight and which countries should receive U.S. equipment.

Here are five key facts that explain how the system works and why the debate matters.

1. America Dominates the Global Arms Trade

The United States supplied about 42% of the world’s major-arms exports from 2021–2025, more than any other country. The Stockholm International Peace Research Institute (SIPRI) defines major arms as large conventional weapons systems, such as combat aircraft, tanks, missiles, artillery and warships—not small arms or ammunition. American weapons reached 99 countries during that period.

This gives the United States significant influence over how allies and security partners equip their militaries. It can also raise questions about American responsibility for how those weapons are ultimately used.

2. U.S. Weapons Go Mainly to Three Regions

  • Europe — 38%: Driven largely by Russia’s invasion of Ukraine and NATO rearmament
  • Middle East — 33%: Focused heavily on aircraft, missiles and air defense
  • Asia and Oceania — 26%: Driven partly by concerns about China and North Korea

Saudi Arabia was the largest individual recipient, accounting for about 12% of U.S. major-arms exports.

3. America Sells Systems, Not Just Weapons

Major exports include fighter jets, missile defenses, precision-guided weapons, tanks and rocket launchers.

But arms packages often include much more:

  • Training
  • Ammunition and spare parts
  • Software and upgrades
  • Maintenance and contractor support

These packages can connect a country to American equipment, training and support networks for decades.

4. A Proposed Sale Is Not an Immediate Delivery

Major sales generally involve State Department approval and congressional notification. A final agreement may then require years of negotiations, production, training and delivery.

An announced sale does not necessarily mean:

  • A contract has been signed
  • The full announced amount will be spent
  • The weapons have already been delivered
  • The transaction will ultimately be completed

Weapons may also be transferred through military aid or from existing U.S. stockpiles rather than through a traditional purchase.

5. The Benefits—and the Risks

The case for arms sales

Supporters argue that arms sales can:

  • Help allies defend themselves
  • Deter attacks from shared adversaries
  • Allow allied forces to operate alongside the U.S. military
  • Strengthen American alliances and influence
  • Support U.S. defense manufacturing and jobs

The concerns

Critics argue that arms sales can:

  • Contribute to civilian casualties
  • Place weapons in the hands of authoritarian governments
  • Intensify regional arms races
  • Create opportunities for diversion or misuse
  • Tie the United States to the conduct of foreign partners

U.S. arms sales can strengthen alliances and help partners defend themselves, but they can also increase the risks of escalation, misuse and civilian harm. The central challenge is deciding who should receive American weapons, what conditions should apply and how their use should be monitored.
