In recent days, multiple open-source intelligence (OSINT) sources have reported that the U.S. Air Force has conducted an unannounced deployment of B-2 stealth bombers to the strategic island of Diego Garcia, located in the Indian Ocean. The island has been leased from the United Kingdom since 1966 despite ongoing sovereignty disputes with the displaced local population. Through flight tracking of refueling aircraft involved in the deployment, radio transmissions, and satellite imagery, reports indicate the presence of between four and five of these bombers, marking a significant show of force in the region.
Expanding on some details of the deployment, it is noteworthy that the operation reportedly began on March 24, when analysts claimed to have heard that a formation of at least four B-2 bombers was in flight, using the call signs PITCH 11, 12, 13, and 14. However, only three reached Diego Garcia, as the aircraft designated PITCH 13 declared an emergency mid-flight and was diverted to Joint Base Pearl Harbor-Hickam. Almost simultaneously, four KC-135 Stratotanker refueling aircraft were transferred from their base in Guam to the Royal Australian Air Force Base in Amberley, suggesting they supported the B-2s’ flight to the island.
Later, two additional bombers joined the deployed aircraft, using the call signs ABBA 11 and 12. These took off from the U.S. West Coast, following a similar trajectory, passing over Australia before reaching Diego Garcia. The final number of aircraft that arrived at the base has not been officially confirmed, as unclear imagery has led to speculation about a larger deployment of up to seven bombers. However, it has been officially confirmed to specialized media that the previously mentioned PITCH 13 bomber made an emergency landing at Pearl Harbor-Hickam.
If the latter is true, it is important to note that Diego Garcia may not have enough appropriate hangars to accommodate such a large number of B-2 bombers. This is a significant concern since these aircraft require climate-controlled shelters to protect their radar-absorbing capabilities—commonly referred to as the B-2 Shelter System. The base reportedly has up to four such hangars, which would be insufficient for the entire deployment. Satellite images also show some of these bombers exposed in the open.
Regarding the objectives of the deployment, various unconfirmed hypotheses have emerged. Among the most prominent is the possibility that the operation aims to increase strikes against Houthi rebel positions in Yemen. Another widely discussed theory is that the deployment serves as a deterrent message to Iran, urging it to halt advancements in its nuclear program. Given that previous strikes on Houthi targets have been conducted directly from the U.S., the second theory seems more likely despite Diego Garcia’s closer proximity to Yemen. This is particularly relevant considering the hardline stance of the new U.S. administration against Tehran, which has already been warned of potential military consequences.
Finally, it is worth noting that the U.S. has been bolstering its presence in the Middle East in recent weeks, conducting rotations of its fighter jets at bases across the region, including the deployment of advanced F-35s. Additionally, with the recent movement of the aircraft carrier USS Carl Vinson and its escort group from the Pacific to the Middle East, a significant naval presence is being maintained in the area. The USS Vinson’s previous position in the Pacific has reportedly been taken over by the USS Nimitz, marking what is expected to be its final deployment.
