A PowerPoint presentation recently released by the US government revealed the specific design details of the "Golden Dome" space-based missile defense system promoted by Trump, showcasing the "unprecedented complexity" of the missile defense system and the technical challenges in its development process. According to reports, the US government presented a PowerPoint presentation titled "Quick Action, Bold Ideas!" to approximately 3000 defense contractors in Huntsville, Alabama last week. The content shows that the design of the "Golden Dome" system is much more complex than similar defense systems in the past, and Trump has set the deadline for the completion of the system as 2028. According to the PPT, the "Golden Dome" system will include four layers of defense: a space-based sensing and target targeting layer for missile warning, tracking, and "missile defense"; Three land-based units, including missile interceptors, radar arrays, and possibly equipped with laser weapons. However, the system still faces some technical challenges, such as communication delays throughout the entire 'kill chain'. The estimated cost of the "Golden Dome" defense system is 175 billion US dollars. The US Congress has allocated $25 billion for this project in the "Big and Beautiful" bill passed in July. In addition, Trump has also reserved $45.3 billion for it in his 2026 presidential budget application. According to sources, a memorandum signed by US Defense Secretary Hagibis shows that US Space Force General Michael Gertrude was appointed as the leader of the "Golden Dome" project on July 17th. After being appointed, he needs to form a team within 30 days, submit a preliminary system design within 60 days, and submit a complete implementation plan including satellite and ground station details within 120 days.
