It is said that the B-2 bombers operating from Diego Garcia uses 30,000 GBU-57 Blts penetrating the huge munitions against the Houthi underground targets.
Since late March 2025, it was six B-2a SPIRIT STALTH It was published in Diego GarciaThe strategic focus of the United States in the Indian Ocean. From there, the bombers participated in the strikes against the Iranian -backed Houthi militias in Yemen.
Initially, some reports stated that B-2s may have been used AGM-158 Jassm (Air confrontation missile to the common surface) Cruise missiles. However, new reports stated that the bomber may also use one of its exclusive weapons: penetration of the huge munitions of 30,000 GBU-57 (MP).

the Soul B-2 It is currently the only plane in the American stock that was wiped to transport MP and spread it, with each striker who is able to carry two bombs. If the reports are correct, this will be the first time that the weapon has been used in the fighting.
When the news is about the publication of B-2 to US strikes against the HouthisWith 30 % of the fleet now in Diego Garcia, many criticized this step, describing a waste of resources. However, the use of B-2 and MP in Yemen sends a clear message to Iran, where the US government negotiates a nuclear deal with Iran to dismantle nuclear and missile programs.
Kills-57 MP
the GBU-57 Human munitions penetration (MP) is a 30,000 -pound GPS bomb (14,000 kg), which is 20 feet long, and is able to penetrate 200 feet of concrete before the explosion. The weapon is available exclusively for the spirit of B-2, which can carry two MPS in the bay of the inner bomb.
The development was assigned after the Iraq war in 2003, when the current Bunker Buster bombs were found to be insufficient for the most solid structures. The US Air Force describes the function of weapons as “reaching and destroying our opponents’ weapons for comprehensive destruction.”
This makes GBU-57 the selection weapon in case of attack on Buried goalsLike Iranian warehouses where the nuclear program is working. It has been reported that the two largest uranium enrichment sites in Iran are the fuel enrichment factory in Natanz, located about three floors underground, and the Fordow, much deeper in a mountain.
Also, one of the shots gives a very clear shot of the weight and types of filling in the bomb. 4400 pounds from AFX-757, which is recently developed by AFRL for use in penetrated bombs, and 762 (752?) Brl from PBXN-114 to make the total about 5,162 pounds of filling. 2/2 Fraanticoat pic.twitter.com/mzuxgwktwk

The secret weapon was promoted in early 2010, and although the type of promotions he received was not publicly published, it was equipped with new fusion and suitable for granting them to give them a greater penetration on the ground. The sources indicate that the GBU-57 has GPS/INS and great hacker directions to allow warheads to reach a specific depth before the explosion is running.
MP photos are very rare, with a few chest over the years. In 2013, we published here An interesting photo of the B-2 sitting next to GBU-57. In December 2018, we found shots from B-2 to drop a mop in a video clip of the 393 bombs, one of the units that manage the hidden spirit launcher as part of 509 BW.
In April 2023, 31 BW posted some photos including an inactive image depicting image, used for training purposes. A month later, 509 BW posted new photos, this time It appears GBU-57.
Diego Garcia
The six of B-2s to Diego Garcia was not announced, and not only was exposed through Osint (open source intelligence) as the bombers were connected with air traffic control while moving to their destination. Information was collected from these connections with height reservations (altrvs) and Usaf ideas Movements that support long -term bomber operations to provide a clearer comprehensive picture.
The first flight of the aircraft began crossing on March 24, 2025, with the reporting of four aircraft. One of them declared a state of emergency during the flight and was transferred to the Berl Harbour-Haikam base, which was identified with Honolulu International Airport. The plane has since returned to the United States
The remaining three bombers continued the journey, with the support of the tankers that were placed in Ambli crane baseAnd then I heard in contact with Australian air traffic control. It is worth noting that Amberley is one of the rules in the region that can host the B-2 spirit.
Hours later, the additional bombers left the United States on the same way via Australia to Diego Garcia. Initially, it was difficult to determine the number of B-2s that already fell in the outpost of the settlement remotely, however satellite images later revealed the presence of at least six bombers.
A few days later, the US Air Force acknowledged that B-2s was already participating in strikes against Houthi goals.
