United States: The United States has selected a design for its next-generation missile defence system, dubbed the ‘Golden Dome’, according to President Donald Trump, who announced the development from the Oval Office. He said the system would be functional before the end of his current term.
The futuristic defence shield, inspired in part by Israel’s Iron Dome but envisioned on a far larger scale, is intended to rescue the US from a wide array of evolving aerial threats, including ballistic missiles, cruise missiles, hypersonic weapons, and even space-based attacks.
Just days into his second term, President Trump had called the Department of Defence to draw up plans for a system capable of defending against what the White House described as ‘the most catastrophic threat’ currently facing the nation.
The Golden Dome will feature cutting-edge technologies deployed across land, sea, and space, including space-based sensors and interceptors. Trump emphasised that the system would be capable of neutralising missiles launched from the other side of the globe or even from space.
General Michael Guetlein, currently the vice chief of space operations at the US Space Force, has been assigned to oversee the ambitious project. The system will fall under a centralised command structure within the US defence apparatus, officials confirmed.

An initial investment of $25 billion has been allocated in a new budget proposal, with Trump suggesting the total cost may reach $175 billion over time. However, the Congressional Budget Office projects that the space-based components alone could push costs up to $542 billion over the next two decades.
The Pentagon has warned that current missile defence abilities have failed to keep pace with advanced weapons being developed by rivals such as Russia and China. A recent Defence Intelligence Agency report highlighted that both nations are actively designing systems to exploit gaps in US defences.
Trump stated that, “There really is no current system. We have certain areas of missile defence, but there has never been anything like this.”
The US is not alone in its interest. Canada has signalled an urge to join the Golden Dome project. Former Canadian Defence Minister Bill Blair said Ottawa was eager to be involved, calling it a matter of national interest and citing concerns about dangers in the Arctic region.
If successful, the Golden Dome could transform US and allied missile defence strategies, providing a security that stretches into orbit and potentially redefines global military balance.
