Tá Northrop (později Northrop Grumman) B-2 Spirit, také známý jako Stealth Bomber, je americký těžký strategický bombardér s nízkou pozorovatelnou technologií stealth určenou pro pronikání husté protiletadlové obrany. Navržený během studené války, je to létající křídlo s posádkou dvou. Bombardér je podzvukový a může používat jak konvenční, tak termonukleární zbraně, jako je až osmdesát 500 liber třídy (230 kg) Mk 82 JDAM naváděných bomb GPS nebo šestnáct 2 400 liber (1 100 kg) jaderných bomb B83. B-2 je jediné uznávané letadlo, které může nést velké zbraně vzduch-země v konfiguraci stealth.

General Characteristics and Design
The Northrop Grumman B-2 Spirit is an American heavy strategic bomber featuring low-observable “stealth” technology. Designed to penetrate sophisticated enemy air defenses, its revolutionary “flying wing” configuration minimizes its radar signature, making it difficult to detect, track, and engage. It is capable of delivering both conventional and nuclear weapons anywhere on the globe with one mid-air refueling.

| Posádky | 2 (Pilot and Mission Commander) |

Dimensions and Stealth
- Wingspan: 52.4 m (172 ft). The immense wingspan is similar to the B-52 Stratofortress, despite having no fuselage or tail.
- Length: 21.0 m (69 ft).
- Height: 5.18 m (17 ft).
- Design: The “flying wing” design lacks vertical stabilizers, which typically produce large radar returns. It uses split elevons on the trailing edge for yaw control.
- Radar Cross-Section (RCS): Classified, but often cited as being around $0.0001\text{ m}^2$, comparable to a large bird or insect, giving it unparalleled stealth performance.
Powerplant and Performance
- Engine: Four General Electric F118-GE-100 non-afterburning turbofan engines.
- Thrust (each): 76.9 kN (17,300 lbf). The non-afterburning design helps reduce the aircraft’s thermal (infrared) signature.
- Speed: High subsonic (Maximum speed around 1,010 km/h or 628 mph).
- Service Ceiling: 15,240 m (50,000 ft).
- Range (Unrefueled): 11,100 km (6,900 mi; 6,000 nmi). Intercontinental range is achieved with one refueling, often extending missions to over 30 hours.
Zbrojení
- Payload: Carries all ordnance internally in two large bomb bays, with a maximum payload capacity of over 18,144 kg (40,000 lb).
- Nuclear Weapons: Capable of carrying B61 and B83 nuclear bombs.
- Conventional Weapons: Can carry up to 80 500-lb (230 kg) JDAM GPS-guided bombs, 16 2,000-lb (907 kg) JDAMs, or specialized weapons like the Massive Ordnance Penetrator (MOP).
- Mission Profile: Designed to drop munitions from high altitudes, greatly increasing the impact area and standoff range for precision-guided munitions.
