Specifications Dimensions Wingspan: 52.43 metres (172 feet 0 inches) Aspect Ratio: more than 5.92 Area: more than 464.50 metres² (5,000.00 square feet) Length: 21.03 metres (69 feet 0 inches) Height: 5.18 metres (17 feet 0 inches) Wheel Track: 12.20 metres (40 feet 0 inches) Powerplant Four General Electric F118-GE-110 non-afterburning turbofans power the B-2, each rated at 84.52kN (19,000lb static thrust) Weights Empty: between 45,360 and 49,900kg (100,000 and 110,000lb) Normal Take-Off: 168,433kg (371,330lb) Maximum Take-Off: 181,437kg (400,000lb) Internal Fuel: between 81,650 and 90,720kg (180,000 and 200,000lb) External Fuel: none Maximum Ordnance: 22,680kg (50,000lb) Performance Maximum Level Speed at High Altitude: about 475mph (764km/h; 416 knots) Range: More than 11,515 miles (18,532 kilometres; 10,000 nautical miles) with one flight refuelling Range with a 16,921kg (37,300lb) warload comprising eight SRAM's and eight B83 bombs: 7,255 miles (11,675 kilometres; 6,300 nautical miles) with internal fuel on a hi-hi-hi mission or 5,067 miles (8,154 kilometres; 4,400 nautical miles) on a hi-lo-hi mission with armament, or 1,152 miles (1,853 kilometres; 1,000 nautical miles) at low level Service Ceiling: 15,240 metres (50,000 feet) Weapon Options The B-2 is built around two large side-by-side weapons bays in its lower centrebody. In front of each bay are small spoiler panels which drop down to produce vortices, ensuring clean weapons release. Rotary launchers in both bomb bays can accommodate a theoretical bomb load of 34,020kg (75,000lb) but, under the US national war fighting SIOP (Single Integrated Operational Plan), any nuclear load would be limited to 9,072kg (20,000lb). While the B-2 can carry 80 Mk 82 227kg (500lb) bombs, it is too valuable to be used as a 'bomb truck'. Its strength, in a conventional role, will lie in its ability to deliver up to 16 smart weapons over a wide area, in a single pass, to 10 metres (30 feet) accuracy. The five prototypes destined for the USAF, along with AV-7, -8 and -9, have been completed to Block 10 standard. This qualifies them to carry 16 B83 freefall nuclear bombs or 16 Mk 82 908kg (2,000lb) conventional bombs. For stand-off strategic missions, the B-2 can carry 16 AGM-69 SRAM II or AGM-129A cruise missiles. The intermediate production standard, Block 20, will add B61 nuclear capability (a maximum of 16) or up to 36 CBU-87, -89, -97 and -98 conventional munitions with a limited conventional PGM (precision-guided munitions) capability from 1997. Two new weapons were added to the list in the form of the AGM-137 TSSAM (Tri-Service Stand-off Attack Missile), a stealthy, subsonic cruise missile with a range of 375 miles (600 kilometres) and a payload of IR- and acoustically-guided sub-munitions, (eight of these would be carried, four on each rotary launcher), and the other, the JDAM (Joint Direct Attack Munition). Fitted to a Mk 82, Mk 84 or BLU-109 weapon, JDAM provides highly accurate targeting guidance through the aircraft's navigation system and an onboard INS.
