interceptor, officially known as the Tu-128. In addition to aerodynamic tests for the Tu-128, the Tu-98 was used for tests with the future Tu-128 RP-7 "Smersch" radar, where the glazed bow was replaced by the device, and the "Kompleks 80" fire control system. The R-4 air-to-air missiles intended as armament for this type were also tested with the Tu-98. The official name of the machine for it was Tu-98LL for "letajuschtschaja laboratorija", flying laboratory. After these tests were completed, the Tu-98 was parked in Zhukovsky for a while before it was scrapped. The Tu-98 also provided information for the construction of the Tu-22. Design The aircraft is built according to the scheme of a mid wing with a swept wing (the sweep angle on the leading edge is 55 degrees). Two AL-7F engines were installed in the stern, and the car was distinguished by long canals and air intakes shifted upwards. The main landing gear was located in the fuselage, which made the wing “clean”, but led to a considerable reduction of stability on the ground. The crew consisted of a pilot - a ship commander, a navigator-operator and a navigator-navigator. All crew stations had ejection seats. The front of the aircraft was a single pressurized cabin. Behind the pressurized cabin there was a technical compartment with photographic equipment (AFA-33/75). The fuel system consisted of 4 main and one centering tanks in the fuselage. Wing - two-spar, caisson design. The control system was performed according to the traditional scheme - with a fixed stabilizer, although for the first time in all control channels, Andrey Nikolayevich agreed to use irreversible hydraulic boosters (his saying is known - “the best booster is the one that stands on the ground”). The front desk had a two-wheel axle, the main ones had two pairs of wheels. For the first time in the domestic bomber, a remote-controlled aft-firing dual AM-23 gun DK-18 installation was used. The guns were aimed by the ARS-1 “Argon” radar sight, the antenna unit of which was placed in the upper part of vertical stabilizer. An additional AM-23 cannon was mounted in the forward right fuselage, which could be fired by the pilot. Rocket-bomb armament aircraft provided suspension FAB-100, FAB-250 or FAB-500 in various combinations, as well as up to 300 ARS-85, or 61 TRS-132, or 18 TRS-212. For naval aviation, it was supposed to arm the aircraft with AMD-500 and
