| Putin and Tu-160Fri, 09 Jan 2009 13:00:38 -0800 by Alexei55555The Tupolev Tu-160 (Russian: ??????? ??-160, NATO reporting name Blackjack) is a supersonic, variable-geometry heavy bomber designed by the Soviet Union. It is similar in configuration to the B-1 Lancer but is significantly faster than the B-1B at altitude with reportedly greater range and payload capacity.Entered service in 1987 with the 184 Guards Bomber Regiment, based at Priluki, Ukraine[1], the Tu-160 was the last strategic bomber designed by the Soviet Union but remains in production, with at least 16 currently in service with the Russian Air Force.Pilots of the Tu-160 call it the White Swan, due to its maneuverability and antiflash white finish.[2]Although several civil and military transport aircraft are bigger, the Tu-160 has the greatest total thrust, and the heaviest takeoff weight of any combat aircraft, and the highest top speed as well as one of the largest payloads of any current heavy bomber.The Tu-160 bears some resemblance to the North American Rockwell B-1A Lancer, although it is significantly larger and has greater range. The Blackjack has a blended wing profile and variable-geometry wings, with sweep selectable from 20° to 65°. Full-span slats are used on the leading edges, with double-slotted flaps on the trailing edges. The Tu-160 has a fly-by-wire control system.It is powered by four Kuznetsov NK-321 afterburning turbofan engines, the most powerful ever fitted to a combat aircraft. Unlike the B-1B, which abandoned the Mach 2+ requirement of the original B-1A, it retains variable intakes, and is capable of reaching speeds slightly higher than Mach 2 at altitude.The Tu-160 is equipped with a probe and drogue in-flight refueling system for extended-range missions, although it is rarely used. The Tu-160's massive internal fuel capacity of 130 tons gives the aircraft a roughly 15-hour flight endurance at a cruise speed of around 530 mph (850 km/h, Mach 0.77) at 30,000 ft (9,145 m).[3]Although the Tu-160 was designed for reduced detectability to both radar and infrared, it is not a stealth aircraft. Russian sources claim that it has a smaller radar cross section (RCS) than the B-1B.[citation needed] Nevertheless, on 25 April 2006 Commander Igor Khvorov claimed that Tu-160s had managed to penetrate the US Arctic zone undetected, leading to a NATO investigation.[4] [5][6]The Tu-160 has an Obzor-K attack radar in a slightly upturned dielectric radome, and a separate "Sopka" terrain-following radar, which provides fully automatic terrain-following flight at low altitude. The Tu-160 has an electro-optical bombsight. Its electronic warfare suite includes comprehensive active and passive ECM systems.The Tu-160 has a crew of four (pilot, co-pilot, weapons systems officer and defensive systems operator) in K-36DM ejection seats. The pilot has a fighter-style control stick, but the flight instruments are traditional "steam gauge" dials. A crew rest area, a toilet, and a galley are provided for long flights. There is no HUD, nor are CRT multi-function displays provided in the original aircraft; however, plans for modernization of all Tu-160s were announced in 2003. They include a new digital flight control system, and the ability to carry new weapon types, such as new non-nuclear long-range cruise missiles.Weapons are carried in two internal bays, each capable of holding 20,000 kg (44,400 lb) of free-fall weapons or a rotary launcher for nuclear missiles; additional missiles may also be carried externally. The aircraft's payload capacity is 45,000kg, making it the heaviest bomber ever built. However no defensive weapons are provided; the Tu-160 is the first unarmed post-World War II Soviet bomber.A demilitarized, commercial version of the Tu-160, dubbed Tu-160SK, was displayed at Asian Aerospace in Singapore in 1994 with a model of a small space vehicle named Burlak attached underneath the fuselage. In 1995 Tupolev announced a partnership with the German firm OHB-System to produce the aircraft as a carrier for the launch vehicle; the German government subsequently withdrew funding in 1998.
