Task: Question Generation
Input (English): Passage: Ford Island continues to be used by the US Navy. It hosts the 34,000-square-foot (3,200 m2) Pacific Warfighting Center for exercises, training and battle simulations. The Admiral Clarey Bridge enabled the Navy to develop a $331 million Pacific tsunami warning center named after Senator Daniel Inouye, replacing the aging facility on ʻEwa Beach. The center's location is controversial because of its location in a tsunami-vulnerable area and the Navy's tsunami-evacuation plan calls for the island's only access point—the Admiral Clarey Bridge—to be opened for ship evacuation (making the bridge inaccessible to land vehicles). The island also continues to host a military brig.Nominally based in Alaska, the Sea-based X-band Radar (SBX-1) arrived on Ford Island in 2006 for maintenance and repairs and has returned several times since. Primarily used as a warhead-detection radar system on a self-propelled floating platform in the Pacific, its presence on the island has been controversial. The platform, with a cost reaching nearly $1,000,000,000, has never actually made it to Alaska and conspiracy theorists argue that the platform is a mobile version of the High Frequency Active Auroral Research Program.In 2013, the Navy unveiled a $4-million training facility, using simulators and virtual reality, at the Naval Undersea Warfare Center Division Keyport on Ford Island. The Fleet Integrated Synthetic Training/Testing Facility (FIST2FAC) was developed to save on training costs with a reusable facility which could emulate electronic, mine and anti-air warfare scenarios instead of real-world training requiring fuel, logistics and deployment costs for ships.
Output (English): What is the full name of the platform with a cost reaching nearly $1,000,000,000?
