a huge dome appeared on the shore of Hawaii and caused immediate confusion among residents and visitors. The structure was visible from the area near Pearl Harbor and was notable for its size and shape, resembling a dome surmounted by pillars.
The appearance of this platform aroused speculation on social networks, with photos and questions about its origins circulating. The mystery grew as more inquiries were made to the U.S. government about the nature of this floating device.
The official explanation came later. he Department of WarThe organization, named after Donald Trump since September last year, explained what its structure is and what its mission is on the territory of the United States.
The dome accommodates the heavy-lift vessel MV Blue Marlin, which is equipped with an X-band underwater radar. According to the Department of the Army, it isMobile semi-submersible oil platform The agency notes that the radar “has advanced capabilities to detect not only ballistic missiles, but also enemy warheads and countermeasures,” and is larger than a soccer field, explaining the visual impact it caused as it approached Pearl Harbor.

The entity recalled that the dome had already stopped at that location on January 9, 2006. 24,000km The ship will depart from Corpus Christi, Texas, and undergo routine maintenance before heading to its homeport of Adak, Alaska. He also emphasized that the structure is part of the Ballistic Missile Defense System (MDA) and operates a floating radar station that can operate even in adverse weather conditions and carry out early warning missions.
For the Missile Defense Alliance (MDAA), the system has the ability to detect small objects. nearly 4000 kilometers awaylike baseball. The agency specified that the technology was first tested in the Gulf of Mexico and Pacific Ocean in 2006.
of MDAA He explained that the system has the following characteristics: Operational milestone of January 28, 2016; when tracking a target representing an intermediate-range ballistic missile fired from a U.S. Air Force C-17 aircraft during a flight test. This operation confirmed the dome’s accuracy and detection range, as well as its usefulness for real-world risk scenarios.
The existence of this structure is Hawaii Address essential technical maintenance and calibration needs to ensure performance. Its deployment strengthens the country’s surveillance capabilities and explains why, despite the visual shock and initial mystery, its arrival is part of the normal circuitry within the U.S. defense system.
