Northrop B-2 Spirit
Northrop Grumman · United States · first flew 1989 · bomber
The USAF's batwing stealth bomber — a tailless flying wing built to slip through air defences undetected.
Recognition (WEFT)
| W — Wings | Mid-mounted, swept |
|---|---|
| E — Engines | 4 × turbofan, embedded-mounted |
| F — Fuselage | Pure flying wing with no fuselage and no tail |
| T — Tail | No tailplane |
WEFT is AircraftIQ's four-point recognition method — how it works.
Spot it by:
- Pure flying wing with no fuselage and no tail
- Sawtooth trailing edge forming a broad shallow chevron
- Four turbofans buried in the wing with shielded exhausts on top
Unmistakable from any angle: a tailless flying wing with a sawtooth trailing edge and no fuselage. Nothing else in service shares the smooth grey batwing planform with a central cockpit bulge.

History
Developed in secret through the 1980s, the B-2 first flew in 1989 and entered service in 1997, reviving Northrop's flying-wing lineage with faceted stealth shaping and radar-absorbent skin. Only 21 were built at enormous cost, and they have since seen combat over Serbia, Iraq, Afghanistan and Libya.
Variants
A single operational model, the B-2A Spirit, with all aircraft individually named after US states. Block upgrades have improved the radar, weapons and stealth coatings rather than spawning distinct variants.
Where you'll see it
An American strategic asset rather than RAF equipment, but B-2s forward-deploy to RAF Fairford and have made rare, headline-grabbing appearances at UK airfields and the Royal International Air Tattoo.
In depth
The Spirit's shape is the answer to a geometry problem: how do you make a large aircraft nearly invisible to radar while still carrying tonnes of bombs across a continent. Jack Northrop had chased the flying wing since the 1940s with his YB-49, a design killed as much by politics and unstable handling as by technology, and he reportedly lived just long enough to be shown the classified B-2 and told his vision would finally fly. The reason it works now and did not then is fly-by-wire; no human could hand-fly a tailless wing with this little inherent yaw stability, so a quartet of split drag rudders at the wingtips open like beaks to steer in yaw, subtly replacing the rudder that a conventional fin would provide. The famous sawtooth trailing edge, the double-W that gives the planform its unmistakable signature, exists to align every edge of the aircraft to just a handful of angles so that radar energy scatters away in a few narrow directions rather than back at the emitter.
Everything about the airframe serves that low observability. The engine intakes sit on top of the wing so the fan faces, which are strong radar reflectors, are shielded from ground-based sets, and the exhausts are flattened trenches that mix cool air with the jet efflux to blur the aircraft's infrared signature. There are no vertical surfaces anywhere, no sharp corners, and the radar-absorbent coatings are so sensitive that for years the fleet required climate-controlled hangars and painstaking maintenance between flights, a major driver of the eye-watering cost that limited the run to twenty-one aircraft, each priced comparably to its weight in gold.
In combat the B-2 has specialised in the opening night of a campaign, when air defences are still intact. Spirits flew the first strikes of the 1999 Kosovo air war directly from their home base at Whiteman Air Force Base in Missouri, thirty-hour round trips across the Atlantic and back, and repeated the feat over Iraq, Afghanistan and Libya. In 2017 and again in later operations they flew some of the longest combat sorties in history, and more recently they were the platform chosen to deliver the largest conventional bunker-busting bombs against deeply buried targets, a mission no other aircraft in the inventory can perform. The one operational loss came not to an enemy but to a takeoff accident at Guam in 2008, when moisture-corrupted sensor data pitched the aircraft up on rotation; both crew ejected safely and the airframe was written off, a billion-dollar reminder of how few there are to lose.
Its rivals are really its successors and predecessors within the same lineage. The B-2 bridged the gap between the fast, low-flying B-1B Lancer, which relied on speed and terrain to survive, and the forthcoming B-21 Raider, a smaller and cheaper stealth wing built on everything the Spirit taught. Against that family the B-2 remains the only wide-body flying wing bomber ever to reach squadron service.
For a British spotter, sightings are precious and unpredictable. The Spirit's one reliable European perch is RAF Fairford in Gloucestershire, which serves as its forward operating base and where Bomber Task Force deployments occasionally bring one or two across for weeks at a time; when a B-2 is in residence the local aviation forums light up. It has made rare flypasts at the Royal International Air Tattoo, and any appearance draws crowds pressed against the fence lines. A useful recognition note for the field: the B-2 never travels far from its tankers and rarely descends low, so most sightings are a distant grey chevron high overhead rather than a close pass, and against a bright sky the aircraft can seem to vanish and reappear as its flat surfaces catch and lose the light, an oddly fitting trait for a machine built to disappear.
