US Weapons Test Ranges: Where America Tests Its Secret Weapons

by José Duncan | Oct 16, 2026 | Aviación militar | 0 comments

Every new American weapon, from a heat-seeking missile to a stealth fighter, has to be shot, dropped, jammed or flown somewhere before it goes to war. For the past 80 years, that somewhere has mostly been a handful of enormous fenced-off deserts in the American West.

This week President Trump announced plans for a new “super range” in Montana. To understand why, it helps to look at the ranges the US military already has, what they were built for, and why even areas the size of small countries are starting to feel cramped.

Nevada: Where Fighter Pilots Go to War

The Nevada Test and Training Range, north of Las Vegas, is the best known. According to Wikipedia, it covers about 4,531 square miles (11,740 km²) of land, with some 5,000 square miles of restricted airspace above it and another 7,000 square miles of shared military operating areas. The land was first set aside as a bombing range in 1940.

Today the range is run from Base de la Fuerza Aérea Nellis and hosts the Red Flag exercises, where US and allied crews fly against a simulated integrated air defence system and some 1,200 targets. The Tonopah Test Range sits within its boundaries, and Groom Lake, the airstrip of Area 51, lies near its north-eastern edge.

White Sands: The Biggest of Them All

White Sands Missile Range in New Mexico covers nearly 3,200 square miles and is described as the largest military installation in the United States. It began in 1941 as the Alamogordo Bombing and Gunnery Range. On 16 July 1945, the first atomic bomb was detonated at the Trinity Site near its northern boundary.

After the war, the US Army brought 100 captured German V-2 rockets to the range and test-fired 67 of them between 1946 and 1951. Nike, Patriot and countless other missiles followed. In 1982 the Space Shuttle Columbia even landed there, on the Northrup Strip, at the end of STS-3. According to TWZ, electronic warfare testing at White Sands is now a bottleneck.

China Lake: Home of the Sidewinder

The Navy’s equivalent is Naval Air Weapons Station China Lake in California’s Mojave Desert, about 1.1 million acres, larger than the state of Rhode Island. It became the Naval Ordnance Test Station in 1943, and in 1950 its scientists developed the AIM-9 Sidewinder, one of the most widely used air-to-air missiles in the world. HARM, JSOW and JDAM were also tested or developed there.

China Lake holds about 85% of the land the Navy uses for weapons testing. In July 2019, two earthquakes of magnitude 6.4 and 7.1 struck with their epicentres inside the station, leaving it “not mission capable” and causing about $5.2 billion in damage.

Utah: The Supersonic Playground

The Utah Test and Training Range, run from Hill Air Force Base, covers about 2,675 square miles of land and more than 19,000 square miles of airspace. It is described as the largest contiguous block of overland airspace authorised for supersonic flight in the contiguous United States. NASA has also used it to land sample-return capsules, including Stardust, Genesis and OSIRIS-REx.

Why They Are No Longer Big Enough

These ranges were built for an age of shorter-range weapons. A hypersonic missile can cross several of them in minutes. Long-range air-to-air missiles, swarms of autonomous drones and powerful jammers all need more room, and they must be tested without interfering with civilian air traffic and radio communications. The Pentagon’s own test and evaluation office has been blunt about it:

“far exceed the current available air space on the open-air ranges”

That is the gap the Montana super range is meant to fill. Senator Tim Sheehy, who has pushed for it, put the case this way after President Trump’s announcement in Kalispell on 14 October 2026:

“adapt and expand our development infrastructure to the realities of modern warfare”

Allies feel the same squeeze. Australia now hosts US hypersonic testing over its vast interior, and allied air forces travel to Nevada every year for Red Flag. The deserts that shaped American air power for 80 years are still essential. They are just no longer enough on their own.

Preguntas frecuentes

What is the largest military test range in the United States?

White Sands Missile Range in New Mexico, covering nearly 3,200 square miles (about 8,300 km²), is described as the largest military installation in the United States. The Nevada Test and Training Range covers more land, about 4,531 square miles, but is an air force training and test range rather than a single installation.

What is the Nevada Test and Training Range used for?

The Nevada Test and Training Range, run from Nellis Air Force Base, is used for air combat training and weapons testing. It hosts the Red Flag exercises, with a simulated integrated air defence system and about 1,200 targets. Tonopah Test Range and the Groom Lake airstrip (Area 51) lie within or beside it.

Where was the Sidewinder missile developed?

The AIM-9 Sidewinder was developed in 1950 by scientists at what is now Naval Air Weapons Station China Lake in California’s Mojave Desert. China Lake holds about 85% of the land the US Navy uses for weapons testing.

Which US range is authorised for supersonic flight over land?

The Utah Test and Training Range, run from Hill Air Force Base, is described as the largest contiguous block of overland airspace authorised for supersonic flight in the contiguous United States. It covers about 2,675 square miles of land and more than 19,000 square miles of airspace.

Why does the US military need a new super range?

Hypersonic missiles, long-range air-to-air missiles, autonomous drones and electronic warfare systems need far more airspace than existing ranges provide. The Pentagon’s test and evaluation office has warned that threat systems and US capabilities now far exceed the airspace available on open-air ranges.

What happened at White Sands Missile Range in 1945?

On 16 July 1945 the first atomic bomb was detonated at the Trinity Site, near the northern boundary of what is now White Sands Missile Range in New Mexico. After the war the range test-fired 67 captured German V-2 rockets between 1946 and 1951.
