How Iran Sank the US Navy in a $250 million war game

Millennium Challenge 2002 was the largest and most expensive war game in Pentagon history, with a staggering price tag of $250 million. (Article republished from InternationalMan.com) It took over two years to design and involved more than 13,500 participants. The goal was clear: showcase how easily the US military could defeat Iran in a hypothetical conflict. Commanding the Iranian forces in the simulation was Paul Van Riper, a retired three-star general and 41-year Marine Corps veteran. His task was to go head-to-head with the full might of the US military, including an aircraft carrier battle group and a large amphibious assault force positioned in the Persian Gulf. But what happened next shocked everyone. Van Riper waited until the US Navy passed through the narrow, shallow Strait of Hormuz—turning them into easy targets for Iran’s unconventional tactics. Using swarms of explosive-laden suicide speedboats, low-flying aircraft with anti-ship missiles, naval mines, and land-based ballistic missiles, Van Riper deployed low-cost but highly effective weapons of asymmetric warfare. In just minutes, he overwhelmed the superior US force and sank all 19 ships. Had this been a real conflict, an estimated 20,000 US sailors and Marines would have died. The outcome was a disaster for the Pentagon. After spending a quarter of a billion dollars, the war game had demonstrated the exact opposite of what they’d hoped. So, what did the Pentagon do? Like a frustrated gamer, they hit the reset button. They rewrote the rules mid-game, scripting the exercise to ensure a guaranteed US victory. The result was no longer a realistic simulation—it became a stage-managed performance. After realizing the integrity of the war game had been compromised, a disgusted Van Riper walked out. He later said:
“Nothing was learned from this. And a culture not willing to think hard and test itself does not augur well for the future.”
The main takeaway from Millennium Challenge 2002 is chilling: aircraft carriers—the most expensive ships ever built—might not survive even a single day in combat against Iran. Against powers like Russia or China, their chances are even worse. They’re oversized, overpriced liabilities. That means the US has potentially wasted trillions on military hardware that may prove useless in a real war. Yet, the US continues to parade aircraft carriers across the globe in shows of force—an intimidation strategy that could backfire catastrophically if an adversary decides to call the bluff. Though the simulation took place over 20 years ago, its lessons are more relevant than ever. Iran has since advanced its asymmetric warfare capabilities dramatically. There’s little reason to believe the US military would fare much better today than it did in 2002. In fact, a full-scale war with Iran today could be even more disastrous. Tensions in the Middle East are at their highest point in a generation—and they’re still rising. The recent Israel-Iran war resolved nothing. If hostilities resume, the US could be dragged into a catastrophic, full-scale war. In other words, the Middle East teeters on the brink of the largest regional war in decades, and the US is on the precipice of its biggest war since Vietnam. Fortunately, you don’t have to be caught off guard. Quite the contrary. Read more at: InternationalMan.com
