Ten US strategic bombers stationed in Diego Garcia reinforce the military posture against Iran and the Houthis. Analysis of the implications.
The deployment of US bombers to Diego Garcia
In May 2025, the island of Diego Garcia, located in the Indian Ocean, will host a significant concentration of US strategic bombers: six B-2 Spirits and four B-52 Stratofortresses. This presence represents about one-third of the operational B-2 fleet, which has 19 aircraft, only 10 to 12 of which are generally available for missions.
The B-2s, deployed since March, have participated in strikes against the Houthis in Yemen. Their ability to penetrate sophisticated air defenses and deliver precision munitions makes them a major asset for targeted operations.
Technical characteristics of the B-2 and B-52
The B-2 Spirit is a stealth bomber capable of carrying nuclear and conventional weapons. It can carry up to two 13,600 kg GBU-57 Massive Ordnance Penetrator (MOP) bombs, designed to destroy deeply buried targets.
The B-52 Stratofortress, in service since the 1950s, remains a pillar of US strategic deterrence. It can carry a wide range of munitions, including AGM-158 JASSM cruise missiles, offering significant operational flexibility.
Geopolitical implications of the deployment
The simultaneous presence of B-2s and B-52s in Diego Garcia sends a strong signal to Iran and its regional allies. The island, located approximately 3,800 km from Iran, is out of range of Iranian ballistic missiles, providing a secure base for air operations.
This deployment comes amid heightened tensions, particularly due to Houthi activities in Yemen and negotiations over Iran’s nuclear program. The United States is seeking to maintain a posture of deterrence while preparing military options if necessary.
Logistical and infrastructural challenges
Diego Garcia has limited infrastructure to accommodate such a concentration of aircraft. The lack of reinforced shelters for the weather-sensitive B-2s poses challenges for maintenance and protection.
Discussions are underway within the Pentagon to upgrade the island’s facilities, including the construction of hangars suitable for the stealth bombers.
Outlook
It is likely that the B-2s will soon be replaced by B-52s, which are better suited to long-range missions and have lower operating costs. However, maintaining a mixed presence could be considered in order to retain strategic flexibility in the face of regional developments.
The situation in Diego Garcia illustrates the United States’ desire to project its air power into sensitive areas, while adapting its posture to operational needs and logistical constraints.
This massive deployment of bombers to Diego Garcia reflects a strengthened deterrence strategy aimed at responding to regional threats while preparing credible military options. The combination of the B-2 and B-52 capabilities provides operational flexibility, which is essential in an unstable geopolitical context.
