You might ask: why not just refuel the helicopter mid-flight? Because the VH-3D was designed in the 1960s for short hops from the White House to Camp David. It has no aerial refueling probe and its top speed is about 160 mph. Crossing the Atlantic would take over 20 hours and require multiple risky stops.
Instead, the support team often sends two helicopters. One is the primary “Marine One” call sign, and the other is a backup. If the primary breaks down in London, the backup is already assembled and ready within hours. It’s the ultimate luxury backup plan.
Practical tip: if you ever see a helicopter flying low over central London with a dark blue fuselage and white top, don’t assume it’s the president. Often, it’s the Marine Two decoy or a support aircraft practicing routes. The real bird is kept under a camouflage net at an undisclosed location.
The British Connection: A Strange Symbiosis
There’s a lovely cultural irony here. The US presidential helicopter fleet is largely built by Sikorsky, an American company—but some of its core components, like the transmission and landing gear, are sourced from UK firms like GKN Aerospace. So when Trump’s helicopter lands in London, it’s partly coming home.
And the British public? They’re famously unimpressed. During the 2018 state visit, locals in Oxfordshire barely glanced at the C-17s landing, preferring to watch the swans on the Thames. There’s a deep, dry humor in watching the world’s most powerful helicopter arrive with zero fanfare.

Fun tip for aviation nerds: if you’re near RAF Northolt (a smaller base in West London), you might spot the helicopter being trucked from Brize Norton. Yes, sometimes it’s driven on a flatbed lorry—with a police escort—wrapped in white tarps, looking like a giant alien cocoon.
