The American Military Buildup in the Gulf: An Analysis of the Largest Military Reinforcement Since the Invasion of Iraq and Its Regional Implications

The Arabian Gulf region is witnessing unprecedented American military activity for over two decades, as the U.S. Central Command continues to deploy air and naval forces at an accelerated pace in what appears to be preparation for multiple scenarios in confrontation with Iran. According to available data from flight tracking and military sources, this buildup is the largest since the invasion of Iraq in 2003, placing the countries in the region in front of a complex security equation that requires a precise reading of developments and their implications.

The current wave of military reinforcements began in mid-February 2026, as flight tracking data showed the arrival of six F-22 Raptor fighter jets from Joint Base Langley-Eustis in Virginia to RAF Lakenheath in the UK on February 17, using the call sign "TREND," which is typically used in long-term deployment operations. These aircraft, representing the pinnacle of American air superiority, belong to the same unit that participated in Operation "Absolute Resolve" to arrest Venezuelan President Nicolás Maduro last month, and were last seen at Lakenheath during preparations for Operation "Midnight Hammer" in June 2025, which targeted Iranian nuclear facilities in Fordow, Natanz, and Isfahan.

In addition to the F-22s, recent days have seen the deployment of 18 F-35 aircraft from the 48th Fighter Wing at RAF Lakenheath towards the Middle East on February 16, accompanied by air refueling aircraft. These planes will join 12 F-35A aircraft from the 158th Fighter Wing of the Vermont Air National Guard, which were deployed to the region last week. The F-35 and F-16 aircraft from Vermont and the German Spangdahlem and South Carolina's McEntire bases form "Wild Weasel" units specialized in destroying enemy air defenses and acting as bait for attacking aircraft, the same role they played in last year's attacks on Iran.

A group of 12 F-16 aircraft from the South Carolina Air National Guard, known as the "Swamp Foxes," arrived at Lajes Field in the Portuguese Azores on February 17, a traditional stopover on the way to the Middle East. Additionally, F-15E Strike Eagle and A-10 Thunderbolt II aircraft originally stationed in the region continue their operations, forming multiple layers of American strike power.

The buildup is not limited to fighter jets but includes an integrated system of support and intelligence aircraft. An RC-135 Rivet Joint signals intelligence aircraft, which was conducting missions from Al Udeid Air Base in Qatar, was moved to the Greek island of Crete in the Mediterranean, a less vulnerable location. Another RC-135 is en route to the island from Florida. Flight tracking data indicates that P-8 Poseidon maritime patrol aircraft are conducting missions in the Middle East, including one that was patrolling the Strait of Hormuz on February 17.

Two E-3 Sentry AWACS for air command and control arrived at RAF Mildenhall in the UK on February 17, with more E-3s on the way to Europe. Additional E-11 BACN aircraft for air communications relay have been deployed in the Middle East and Europe, with over 12 refueling aircraft en route to Europe on February 17 and 18. According to reports from The Wall Street Journal, the United States has conducted over 150 military airlift flights to transport weapon systems and ammunition to the Middle East.

On the maritime front, the aircraft carrier USS Abraham Lincoln and its strike group are present in the Arabian Sea, carrying an air wing that includes F-35C aircraft, E/A-18 Super Hornet fighters, and EA-18 electronic attack aircraft. The aircraft carrier USS Gerald R. Ford, which had been supporting U.S. operations in the Caribbean, is now being redirected towards the eastern Mediterranean. Ford left the area of responsibility of U.S. Southern Command and is now in the Atlantic Ocean, according to U.S. officials on February 17. Ford carries F/A-18 and EA-18 aircraft. Both carriers are accompanied by warships capable of defending against ballistic missiles and carrying Tomahawk cruise missiles, including Arleigh Burke-class guided missile destroyers.

These reinforcements come in the context of the Trump administration demanding that Iran agree to a new nuclear deal that prohibits uranium enrichment. Although the Iranian foreign minister stated on February 17 that "the path to a deal has begun," there does not appear to be an imminent agreement on the horizon. Air & Space Forces magazine revealed that the U.S. military is moving to re-equip its stockpile of GBU-57 Massive Ordnance Penetrator bombs designed to destroy underground fortified facilities, which were used against Iranian underground nuclear facilities last June.

From a regional perspective, this military buildup places the Gulf Arab states in a delicate and complex position. On one hand, these countries view American protection as a cornerstone of their security strategies and see the intense American military presence as a deterrent to any potential Iranian threats. On the other hand, the presence of Gulf military bases as platforms for American military operations against Iran could expose them to Iranian retaliatory responses, whether through ballistic missiles, drones, or regional proxies.

The significance of this buildup lies in the fact that it includes the same military assets that participated in Operation Midnight Hammer, which inflicted severe damage on the Iranian nuclear program. That operation used seven B-2 Spirit bombers to strike two nuclear sites in Fordow and Natanz, while a site in Isfahan was hit with Tomahawk cruise missiles. F-22 aircraft played a protective role for the attacking planes during that operation, as Chairman of the Joint Chiefs of Staff General Dan Keen explained to reporters after the mission. This pattern of deployment indicates that the United States is preparing its military options with the same level of detail it followed last year.

Historically, F-22 aircraft have been used in the Middle East to lead strike groups entering dangerous areas, although Iran has limited capabilities in air combat. Raptors have also led strike groups in Syria during the peak of the American air campaign against ISIS, helping to protect other aircraft and serving as a deterrent to Russian or Syrian aircraft when Bashar al-Assad's regime was in power. Raptors have previously been deployed in the region to counter the threat of drones and Iranian missile attacks on American forces and American partners in the region.

For the Gulf states, these developments raise several strategic questions. First, what level of coordination is required with the United States in the event of military escalation? Second, how can self-defense capabilities, especially air and missile defense systems, be enhanced to counter potential Iranian retaliation? Third, is there a need for broader Gulf coordination to ensure the protection of critical infrastructure, especially oil and gas facilities, ports, and water desalination plants?

From Iran's side, satellite images indicate that it has recently built a concrete shield over a new facility at a sensitive military site and covered it with soil, advancing work at a site that was bombed by Israel in 2024. This indicates that Tehran is taking measures to protect its vital facilities, but at the same time faces a dilemma: escalation could bring harsher strikes, while accepting Washington's terms means undermining its nuclear program in which it has invested for decades.

The most important question remains: is this military buildup a negotiating pressure tool to extract Iranian concessions, or is it actual preparation for a large-scale military operation? History shows that U.S. administrations have used both approaches. However, the scale of this buildup and the quality of the deployed assets, especially those specialized in suppressing air defenses and striking fortified targets, indicate the seriousness of military preparations. For the Gulf states, wisdom dictates preparing for the worst-case scenario while working to avoid it through diplomatic channels. Balancing national security and regional stability requires political acumen and deterrent military capabilities at a time when the Gulf is witnessing the largest foreign military buildup in over two decades.
