The B-2A is designed for multiple missions including deep strike penetration against heavily defended targets. The aircraft combines several active and passive low-observable systems to maximize its stealthiness. The stealthiness of the aircraft is augmented by it's long range (6,000+ nautical miles un-refueled), large payload (40,000 lbs.) and near precision weapons delivery. These characteristics combine to make the B-2A one of the USAF's most capable and versatile weapon systems. The B-2 is constructed primarily of composite materials (approximately 80%) with some internal load bearing structures made of aluminum or titanium. The shape of the aircraft contributes to its stealth and a special radar absorbing paint further reduces its radar image. The heat of the engine is masked by an exhaust channel which hides it from below the aircraft and disperses it behind the aircraft. These passive stealth systems - combined with sophisticated avionics - give the B-2A extremely small radar and infrared heat signatures. The aircraft also incorporates electronic counter measures avionics systems to hide from or confuse enemy defenses. The cockpit suite incorporates 3 video display screens for each of the 2 crew members. Most flight data is displayed on one of the terminals with each terminal having the capability to sort required flight information so as to not over load the crew with unnecessary data. The aircraft has conventional ejection seats. The aircraft is a flying wing with no fuselage or empennage sections having the crew compartment, bomb bay, engine bays and landing gear bays all incorporated into the center wing section. The B-2 is controlled by surfaces located along the trailing edge of the wing. The outboard wing trailing edge has split (drag) rudders which provide yaw control while three sets of elevons (outboard, mid, inboard) provide pitch and roll control. The B-2A achieved initial operating capability in April 1997 with the 509th Bomb Wing at Whiteman AFB, Missouri. Although the USAF has 21 B-2A's, less than half of them are actually assigned to the 509th, the remainder of the fleet aircraft are in various upgrade programs to bring them up to full operational capability.
