Role	Stealth strategische zware bommenwerper
Eerste vlucht	17 juli 1989
Gebouwd	21

De Northrop (later Northrop Grumman) B-2 Spirit, ook bekend als de Stealth Bomber, is een Amerikaanse zware strategische bommenwerper, met laag waarneembare stealth-technologie ontworpen voor het doordringen van dichte luchtafweer. Ontworpen tijdens de Koude Oorlog, is het een vliegend vleugelontwerp met een bemanning van twee. De bommenwerper is subsonisch en kan zowel conventionele als thermonucleaire wapens inzetten, zoals tot tachtig 500-pond klasse (230 kg) Mk 82 JDAM GPS-geleide bommen, of zestien 2.400-pond (1.100 kg) B83 kernbommen. De B-2 is het enige erkende vliegtuig dat grote lucht-naar-oppervlakte standoff wapens in een stealth-configuratie kan dragen.

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.

Property	Typical Value (B-2A Block 30)
Role	Multi-role Strategic Heavy Bomber
Fabrikant	Northrop Grumman Corporation
First Flight	July 17, 1989
No. Built	21 (20 remain in service)
Bemanning	2 (Pilot and Mission Commander)
Mass (Empty Weight)	72,575 kg (160,000 lb)
Max Takeoff Weight	152,634 kg (336,500 lb)

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.

Bewapening

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.
