How Does the B-2 Bomber Fly for 40 Hours Without Refueling?
Even with its massive fuel capacity, the B-2 relies on aerial refueling from tanker aircraft such as the KC-135 or KC-46. This capability lets it extend missions indefinitely, making 40+ hour flights possible.
Massive Fuel Capacity Built In
The B-2 Spirit carries nearly 75,000 pounds of internal fuel, enabling intercontinental missions before refueling, thanks to its wing-integrated storage design.
Efficient Stealth Design
Its flying wing shape minimizes aerodynamic drag, cutting fuel consumption significantly. This design ensures efficiency, allowing the bomber to perform ultra-long endurance missions globally.
In-Flight Refueling Capability
The B-2 can refuel midair using tanker aircraft like the KC-135 or KC-46, extending missions indefinitely and enabling record-breaking 40+ hour flights.
Advanced Engine Technology
Equipped with four GE F118-GE-100 engines, the bomber achieves optimized endurance, reduced fuel burn, and infrared stealth, maximizing performance on prolonged global operations.
Crew Rotation in the Cockpit
With two alternating pilots, sleeping space, and rations, the B-2 cockpit supports survival during 40-hour missions, maintaining operational efficiency throughout demanding flights.
Global Strike Doctrine
The B-2 was designed for nonstop missions, launching from Missouri to strike worldwide targets without foreign bases, supported by aerial refueling and extreme endurance.
Proven in Real Combat
In Kosovo and Iraq, B-2s flew 30+ hour missions from Missouri, struck targets overseas, and returned without landing abroad, proving unmatched endurance.
