Tu-22DP (Dal'nego Perekhvata, long-range interception)/ DP-1 is a long-range interceptor project based on the Tu-22M2 (later on the basis of the Tu-22M3). R & D was conducted by the AN Tupolev Design Bureau together with GosNIIAS. It was assumed that the DP could also carry strike weapons. Tu-344 A canceled civilian supersonic aircraft based on the Tu-22M3, designed to carry . Developed by Tupolev Design Bureau (ANTK named after A. Tupolev) within the framework of conversion program in the second half of the 1990s.<ref>Under the signs of "ANT" and "TU" // Aviation and Cosmonautics. - 2000. - # 11.</ref> The development of the aircraft began in the 1990s with the emergence of interest and demand for supersonic business jets (SBJ). Since the creation of an aircraft from scratch requires a large investment, Tupolev Design Bureau decided to create an SBJ-class aircraft based on Tu-22M3. However, the project proved to be unpromising at the time, as the aircraft was supposed to be used internationally, but did not meet international environmental standards of the day. Tu-22M3 with SVP-24-22 Modernized Tu-22M3 of the Russian Air Force fitted with a new sighting and computing system SVP-24-22 Gefest, instead of the NK-45 Vakhta-2 complex. The SVP-24-22 includes a new and more powerful SV-24 onboard computer, UVV-MP-22 input-output device, flight information generation unit – BFI, aviation collimator indicator KAI-24, radio navigation system SRNS-24 with the A737 satellite receiver and the solid-state information storage device TBN-K-2 to save data of the navigation-targeting complex SVP-24-22 and of the flight recorder. 5 modernized aircraft entered service in 2015, 2 in 2017, 1 in 2018, 2 in 2019 and 2 in 2022. Tu-22M3M Tu-22M3 for the Russian Air Force with engines from Tu-160M2 (NK-32-02), 80 percent of avionics are replaced or upgraded, including SVP-24-22 bombsights, a phased array NV-45 radar, GLONASS navigation system, modern digital glass cockpit and engine controls, electronic warfare countermeasures, and the ability to use precision air-to-surface weapons. The modernization also counts with installation of mid-air refueling equipment, removed from existing aircraft in 1979 under the SALT II agreement, that will significantly increase the combat radius of the bomber. The Russian Ministry of Defense intends to upgrade up to 30 aircraft out of approximately 60 Tu-22M3s currently in service to the advanced Tu-22M3M variant. Can carry 3 Kh-32 or 4 Kh-47M2 Kinzhal missiles. Service life will be extended to 40–45 years. On 16 August 2018, the first
