Tu-134B-3

The Tupolev Tu‑134B‑3 is a Soviet‑designed short‑range jet airliner that entered service in the early 1970s. Developed from the original Tu‑134, the B‑3 variant incorporated a more powerful Soloviev D‑30 turbofan engine, updated avionics and a stretched fuselage that allowed eight additional passenger seats. First flown on 15 December 1974, the aircraft quickly became the workhorse of Aeroflot’s domestic network, later serving airlines across the Eastern Bloc and several non‑aligned countries. Its all‑metal low‑wing design, swept‑back wings and retractable tricycle landing gear gave the Tu‑134B‑3 a cruising speed of about 800 km/h and a range of roughly 2,200 km, making it suitable for regional routes. Key features include a modernized cabin with improved sound insulation, stretch‑seats, and a cockpit equipped with dual VHF radios, navigation aids and autopilot. Over 300 units were built before production ended in 1989, and many remained in service well into the 21st century. The Tu‑134B‑3 is celebrated for its reliability, ease of maintenance and role in expanding air connectivity throughout the Soviet sphere, marking a pivotal chapter in the evolution of short‑haul jet transport and influence.
