Doomsday Missile Test: U.S. Sends Strong Warning
On the sixth day of America’s active war against Iran, the US Air Force test-fired the Minuteman III — the most destructive land-based weapon in its arsenal. Washington calls it routine. The rest of the world is not so sure.
What Happened: The Launch
At 11:01 PM Pacific Time on Tuesday, March 3, 2026 — the sixth day of the US-Israeli war on Iran — the United States Air Force Global Strike Command test-fired an unarmed LGM-30G Minuteman III intercontinental ballistic missile from Vandenberg Space Force Base near Santa Barbara, California.
The test, officially designated Glory Trip 255 (GT-255), carried two non-nuclear re-entry vehicles across more than 4,200 miles of Pacific Ocean before striking a predetermined target at the Kwajalein Atoll in the Marshall Islands with what the Air Force called “absolute precision.” The full flight lasted approximately 30 minutes.
The missile was drawn from a silo of the 91st Missile Wing at Minot Air Force Base, North Dakota. Operators from all three US ICBM wings participated: the 90th Missile Wing at F.E. Warren (Wyoming), the 341st at Malmstrom (Montana), and the 91st at Minot (North Dakota). Data from the test is being shared with the Department of Defense, the Department of Energy, and US Strategic Command.
The timing was impossible to ignore. The launch came six days into an active shooting war with Iran — one in which the US Senate had just voted 53–47 to reject limits on Trump’s war powers, a US submarine had sunk an Iranian Navy frigate near Sri Lanka, and the New START nuclear arms treaty with Russia had expired the previous month — removing all formal limits on both nuclear arsenals for the first time since the Cold War.
Air Force Global Strike Command stated the launch is “not in response to world events” and is “a key component of a data-driven program that has been in place for decades, involving over 300 similar tests designed to validate the performance of the weapon system.” The test was described as scheduled years in advance.
What Is the Minuteman III — The Doomsday Missile Explained
The LGM-30G Minuteman III is the United States’ only active land-based intercontinental ballistic missile. Built by Boeing and first deployed in June 1970, it has been in continuous service for over 55 years. Standing 59 feet 10 inches tall and weighing 78,000 pounds, it is powered by three solid-propellant rocket stages — meaning no pre-launch fuelling is needed. It sits permanently on high alert, 24 hours a day, ready to launch within minutes of a presidential order.

A single Minuteman III warhead carries a destructive yield estimated at up to 20 times the bomb dropped on Hiroshima, which killed approximately 140,000 people. The missile can carry multiple such warheads, each independently guided to a separate target. When deployed at scale, the resulting nuclear detonations and radiation fallout could render large portions of the Earth uninhabitable — earning it the “doomsday” label. It is not a battlefield weapon. It is a weapon of civilizational last resort.
The MIRV Factor: One Missile, Multiple Cities
The GT-255 test explicitly validated the system’s ability to deploy two separate re-entry vehicles with absolute precision. Arms control analysts note this has taken on new significance now that New START has expired. General Davis specifically cited the test’s purpose as validating “our ability to deliver multiple, independently targeted payloads.” In plain terms: one missile, multiple cities — simultaneously.
The Nuclear Triad: Where the Minuteman III Fits
The Minuteman III forms the land leg of America’s nuclear triad — a deliberately redundant three-platform system designed so that no enemy first strike could ever eliminate the US ability to retaliate. Each leg operates independently through a separate domain, making simultaneous destruction of all three virtually impossible.
~400 silos across three US states. Solid fuel. Permanent launch-ready alert. 30-minute global strike time. Tested during the Iran war on March 3, 2026. Controlled via hardened silo networks with E-6B aircraft backup.
Armed with Trident II D5 missiles. Operate submerged and undetectable. Their position is never known — making them impossible to destroy in a first strike. The most survivable leg of the triad.
Long-range strategic bombers delivering nuclear bombs and cruise missiles. Most flexible leg — planes can be recalled after launch. B-52Hs currently active in the Middle East theatre.
Minuteman III silos connect to launch control centres via hardened underground cables with redundant networks linking directly to national command authority at all times. Should all ground links be destroyed, E-6B Airborne Command Post aircraft can assume control and transmit launch orders directly — ensuring the system functions even in a full decapitation strike against US leadership.
Timeline: From the Iran War to the Doomsday Test
Previous Minuteman III Test
A Minuteman III was test-launched in November 2025 — shortly after President Trump publicly called for restarting US nuclear weapons testing, raising global alarm about a new nuclear arms race.
New START Treaty Expires
The last nuclear arms control treaty between the US and Russia expires. Both nations now operate with zero legal constraints on warhead numbers — for the first time since the Cold War.
Trump Orders Operation Epic Fury
Trump authorizes joint US-Israel assault on Iran from Air Force One after nuclear talks collapse in Oman. Trump publicly warns: “The big one is coming.”
War Begins — Khamenei Killed
900+ US strikes and 200 Israeli jets hit Iranian targets. Supreme Leader Khamenei is killed. Iran launches Operation True Promise IV — retaliating with missiles and drones against Israel, US bases, and Gulf states simultaneously.
Iran Deploys Fattah-2 Hypersonic Missile in Combat
Iran conducts its first operational use of the Fattah-2 hypersonic missile (Mach 15, ~1,500 km range), designed to evade air defences. Three US F-15Es are shot down over Kuwait.
GT-255: Minuteman III Fires at 11:01 PM PT
Unarmed Minuteman III launches from Vandenberg. Two re-entry vehicles travel 4,200+ miles across the Pacific. Strike Kwajalein Atoll target with precision. Senate simultaneously rejects curbing Trump’s war powers 53–47.
US Submarine Sinks Iranian Frigate IRIS Dena
A US submarine sinks the Iranian Navy frigate IRIS Dena near Sri Lanka — the first US submarine attack on a surface warship since World War II. Approximately 80 Iranian sailors killed. Iran calls it a war crime.
Day 6 — War Widens, Nuclear Anxiety Peaks
Defence Secretary Hegseth says conflict could last eight weeks. Iran continues missile barrages. Doomsday Clock at closest-ever position to midnight. Global nuclear anxiety at its highest since the 1962 Cuban Missile Crisis.
What Officials and Experts Are Saying
Despite official insistence that the test was pre-scheduled and unrelated to the war, the combination of factors is without modern precedent: an active war, an expired arms treaty, Iran’s first-ever hypersonic missile combat use, and a test explicitly demonstrating MIRV-capable re-entry vehicles — all in the same week.

The Bigger Picture: A World on Nuclear Edge
The GT-255 test lands in a global nuclear environment more volatile than any since the Cuban Missile Crisis. Every major nuclear power is either modernizing, expanding, or signalling its arsenal — while the diplomatic frameworks that constrained nuclear competition for decades have either expired or collapsed entirely.
Active war with Iran. New START expired. MIRV test during live conflict. Senate gave Trump unchecked war powers. Sentinel ICBM modernization on track for 2030s. B-21 Raider stealth bomber entering service.
New START expired — zero warhead limits remain. Nuclear modernization ongoing. Repeated nuclear threats over Ukraine. Strategically benefits from US military attention being consumed by the Iran war.
Rapidly expanding nuclear warhead count. New ICBM silo fields under construction. Condemned US strikes on Iran. Faces acute oil supply disruption through the closed Strait of Hormuz.
Tested new ICBM with hypersonic re-entry vehicle in 2025. Announced nuclear-powered submarine programme. Watches US willingness to strike non-nuclear states unilaterally with great attention.
The IAEA confirmed no Iranian nuclear facilities were destroyed as of March 5. Iran’s nuclear programme remains operational — leaving Operation Epic Fury’s primary stated objective completely unresolved.
Actively debating an independent nuclear deterrent. France and UK arsenals being considered as an EU umbrella. Germany and Poland weighing nuclear latency for the first time since World War II.
The Bulletin of the Atomic Scientists warned in 2026 that “strategic competition among major powers is showing signs of becoming a full-blown arms race,” citing expanding warhead counts, modernization programmes, and “new concerns about the possible resumption of nuclear testing.” The clock stands at its closest-ever position to midnight in its 77-year history.
What Comes Next?
The Minuteman III is scheduled for eventual replacement by the LGM-35A Sentinel ICBM, with initial operational capability targeted for the early 2030s. However, the Government Accountability Office confirmed the Air Force is now evaluating options to keep the Minuteman III in service through 2050 due to Sentinel programme delays — meaning this 55-year-old “doomsday” missile may serve for another quarter century.
As the US-Iran conflict enters its second week with no diplomatic channel open, no ceasefire in sight, Defence Secretary Hegseth projecting up to eight more weeks of fighting, and Iran’s nuclear sites confirmed intact, the war has passed thresholds that would have seemed unthinkable two weeks ago. The Senate has given the president unchecked authority to continue. A US submarine has sunk an Iranian warship. And from California, a missile that can reach any city on Earth in 30 minutes just flew 4,200 miles across the Pacific.
Washington insists that was routine. The world is watching something else entirely.
Operation Epic Fury was launched with the explicit goal of dismantling Iran’s nuclear programme. As of Day 6, the IAEA has confirmed that none of Iran’s nuclear facilities have been destroyed. The war’s primary objective remains completely unachieved — while the Doomsday Clock ticks closer to midnight with every passing day.
