Mapping The Build-Up: How US Forces Moved Into Position Before Striking Iran

The Middle East has erupted into one of the most volatile conflicts of the 21st century, with war between Iran, the United States, and Israel entering its fifth day on Wednesday. The crisis began after coordinated U.S. and Israeli military strikes killed Iran's Supreme Leader Ayatollah Ali Khamenei and multiple senior commanders, plunging the region into full-scale conflict

The offensive - codenamed "Operation Epic Fury" - targeted hundreds of Iranian strategic, military, and nuclear sites. President Donald Trump and Israeli Prime Minister Benjamin Netanyahu described the operation as a preemptive effort to neutralize what they called imminent threats from Tehran's missile and nuclear programs. Both leaders confirmed that Khamenei was among those killed in the initial strikes.

US Deploys Unprecedented Force in Middle East

Before attacking Israel, the United States had moved the largest concentration of military assets to the Middle East in over two decades, positioning a formidable array of aircraft and naval forces around Iran.

The deployment, which began in late January and accelerated through February, includes multiple aircraft carrier strike groups, fighter jets, surveillance aircraft, and warships positioned from the Eastern Mediterranean to the Gulf of Oman. According to Pentagon tracking and independent open sources, these moves are the most significant US force posture increase in the Middle East since the lead-up to the 2003 Iraq War.

How US Military Assets

Graphic maps circulated by defense analysts show US military assets deployed broadly around Iran's borders: from fighter jets in Jordan, Saudi Arabia, the UAE and Israel, to long-range reconnaissance aircraft based in Crete, Greece. MQ-4C Triton drones and P-8 Poseidon surveillance aircraft were spotted flying regular sorties over the broader region.

On the naval front, the USS Abraham Lincoln Carrier Strike Group has been operating in the Arabian Sea, accompanied by destroyers and support vessels. More significantly, the USS Gerald R. Ford Carrier Strike Group, the U.S. Navy's newest and most advanced carrier, has been redirected from the Caribbean and is operating in or near the Eastern Mediterranean, marking a rare two-carrier presence in the broader Middle Eastern theater.

This posture placed strike aircraft and long-range naval fires within reach of Iranian airspace and critical infrastructure, a capability that dramatically expanded Washington's military options.

The sheer number of combat aircraft, including stealth fighters like the F-22 and F-35, and surface warships equipped with Tomahawk cruise missiles creates a posture capable not only of deterrence but of sustained offensive operations.

Heavy Strikes and Immediate Retaliation

Since the operation began, U.S. and Israeli forces have carried out over 1,200 strikes across Iran, including air and missile attacks on command structures, missile production facilities, and military installations throughout the country. Iran's air defense systems and strategic infrastructure have been primary targets as coalition forces seek to degrade Tehran's ability to wage asymmetric warfare.

In response, Iranian forces have launched sustained missile and drone barrages toward military bases hosting U.S. troops across the Gulf region, including in Kuwait, Bahrain, Qatar, and the United Arab Emirates. Explosions have also been reported in Iran's capital and other major cities, while Iranian allied militias and Hezbollah have opened a secondary front, firing rockets into northern Israel and Lebanon.
