Rockwell International B-1B Lancer

Role: Long-range multi-role strategic bomber.
Here is some info I got from George Raihala, B-1 Instructor:

The info on the Bone is way out of date. The jet does not drop ALCMs (due to the START treaty), and all B-1s are now conventional only. Also, in addition to the Mk82 and the Mk62 mine, all B-1s can carry CBU-87/89/97. In a couple of months, the first JDAM capable jets will arrive at Ellsworth AFB, having successfully dropped many JDAMS at Edwards AFB.

DESIGN FEATURES: Cantilever low-wing fail-safe blended wing/body structure with variable geometry on outer panels. Wing sweep is actuated by screwjacks driven by four hydraulic motors; it can be powered by any two of the aircraft's four hydraulic systems, asymmetric movement being prevented by a torque shaft between the two screwjacks. Sweep actuators are covered by a leading-edge `knuckle' fairing which prevents a gap from opening when outer panels are swept back. Aft of the wing pivot on each side are overwing fairings which blend the wing trailing-edge and engine nacelles. Each of outer wing panels, have 15o of leading-edge sweep when fully forward and 67o 30' when fully swept. Cantilever tail unit with sweepback on all surfaces.
LANDING GEAR: Hydraulically retractable tricycle type. Each main unit, which retracts inward and rearward, has two pairs of wheels in tandem.
POWER PLANT: Four General Electric F101-GE-102 augmented turbofans, each rated at 136.9 kN (30780 lb st), mounted in pairs beneath fixed centre-section of wing, close to CG, to provide optimum stability in low-altitude turbulence conditions.
ACCOMMODATION: Four-man operational crew comprising pilot, co-pilot and two systems operators (defensive and offensive) on Weber ACES II ejection seats in a pressurised crew compartment. Pilots have control sticks rather than conventional bomber/transport yokes.
AVIONICS: Standard GFE (government furnished equipment) includes communications, IFF, ILS, intercom, some navigation equipment, Honeywell ASN-131 SPN/GEANS radar altimeter (similar to that in B-52) and altimeter indicator, rescue beacon and transponder.
ARMAMENT: Three internal weapons bays, comprising 9.53 m (31 ft 3 in) double bay forward of wing carry-through structure and a single 4.57 m (15 ft) long bay aft, with hydraulically actuated doors. Forward bay incorporates a movable bulkhead permitting accommodation of a wide variety of weapons, of various sizes, and mixed loads. Internal capacity in a nuclear role for up to eight AGM-86B air-launched cruise missiles (ALCMs), 24 AGM-69 short-range attack missiles (SRAMs), 12 B-28 or 24 B-61 or B-83 free-fall nuclear bombs; or, in a non-nuclear role, for up to 84 500lb Mk 82 bombs or 500 lb Mk 36 mines. Six external stores stations beneath fuselage, on which can be carried an additional 12 ALCMs. The forward and aft bays can be combined to carry eight ALCMs on a common strategic rotary launcher.
