If Washington goes dark — nuclear strike, decapitation attack, catastrophic disaster — the first aircraft in the sky won’t be Air Force One. It will be a helicopter lifting VIPs from the Pentagon, the Capitol, and secure locations across the National Capital Region. For decades, that helicopter was the UH-1N Twin Huey, a Vietnam-era airframe held together by maintenance hours and institutional stubbornness. Now the Air Force is replacing it with something dramatically more capable: the HH-60W Jolly Green II. The FY2027 budget confirms the plan. Twenty-six HH-60Ws will be modified for VIP airlift and continuity-of-government operations at Joint Base Andrews, taking over the Air Force District of Washington (AFDW) mission that the Twin Hueys have performed since the Cold War. It is one of the most sensitive helicopter missions in the U.S. military — and it is getting a generational upgrade.

The Doomsday Taxi

The AFDW helicopter mission is deliberately low-profile. The choppers fly regular patrols over the capital, maintain alert crews around the clock, and practise evacuation routes that are classified above the level most Air Force officers will ever see. When the President is at the White House, these helicopters are part of the layered response designed to keep the government functioning if the worst happens. The UH-1N has done this job capably, but its limitations are real. Its range is short — roughly 230 nautical miles without refuelling. Its speed tops out around 100 knots. Its avionics date to an era when GPS was a classified experiment. In a genuine crisis, the Twin Huey’s performance envelope becomes a constraint on how far and how fast you can move the people who need moving. The Jolly Green II changes every variable. It is faster, with a cruise speed north of 150 knots. It carries more — both passengers and fuel. And critically, it retains the aerial refuelling probe that the HH-60W was designed around for its primary combat search-and-rescue mission. That probe means range is effectively unlimited. A Jolly Green can plug into a tanker and fly until the crew runs out of consciousness, not fuel.

Why Not the Grey Wolf?

The original plan was straightforward. The Air Force would buy 80 Boeing-Leonardo MH-139A Grey Wolves to replace the UH-1N fleet at Andrews and at nuclear missile bases across the Great Plains. The Grey Wolf won the competition in 2018. But the programme stumbled. Delivery delays, integration issues, and questions about whether the Grey Wolf’s performance justified its cost led the Air Force to reconsider. By 2025, the service revealed it was looking at the HH-60W instead — an aircraft already in full-rate production, already proven in combat (including a dramatic pilot rescue during operations over Iran), and already embedded in the Air Force logistics chain. The decision is a blow for the MH-139A programme but a pragmatic one. The Jolly Green II is a known quantity. It has flown combat rescues in contested airspace. It has the sensors, the armour, and the countermeasures that a doomsday mission in the world’s most surveilled airspace demands. The Grey Wolf was designed for a less demanding threat environment.

Combat Pedigree Meets Capital Security

The HH-60W’s recent combat record adds weight to the decision. During the Iran campaign, a Jolly Green II crew executed a contested pilot recovery that the Air Force has described as one of the most complex combat rescues since Vietnam. The aircraft’s advanced infrared countermeasures, defensive systems, and ability to refuel in flight were all validated under fire. Those same capabilities translate directly to the AFDW mission. Washington’s airspace is a target-rich environment for adversary planners — and any crisis severe enough to trigger continuity-of-government operations is likely to involve threats that the UH-1N was never designed to survive. Twenty-six Jolly Greens at Andrews. The most important helicopter mission you’ve never heard of just got its biggest upgrade in half a century.
