ShapeFlying wing with buried engines
No tail and engines hidden inside the wing keep radar reflections and engine heat low, so defences struggle to track it.
EnginesTwo engines, no afterburners
Two Pratt & Whitney turbofans sit inside the wing with no afterburners: less heat, a smaller radar signature and modest fuel use, at the cost of top speed.
SystemsOpen architecture
Computers and sensors use open interfaces, so new software and weapons can be added without redesigning the aircraft.
DigitalDigital engineering and a digital twin
The jet was designed on a detailed computer model, and Northrop keeps a cloud-based digital twin of it to plan maintenance and support across the fleet's life.
