was completed in March 2020. Tu-116 Designed as a stopgap in case the Tu-114A was not finished on time, two Tu-95 bombers were fitted with passenger compartments. Both aircraft had the same layout: office space, a passenger cabin consisting of two sections which could each accommodate 20 people in VIP seating, and the rest of the cabin configured as a normal airliner. Both aircraft were eventually used as crew ferries by the various Tu-95 squadrons. One of these machines is preserved at Ulyanovsk Central Airport. Modernization Starting in the 2000s, the Russian air force started to study different options for the modernisation of its Tu-95MS fleet. Even before the start of the modernisation program, in 2003 the aircraft were made compatible with the Kh-555 missile. Then, the proper modernisation program was initiated. Development officially started when a research and development contract was issued to Tupolev by the Russian Defence Ministry, on 23 December 2009. The modernisations are only applied to the Tu-95MS16s using the K-016 Sprut missile initialisation system, and not to the aircraft using the older K-012 Osina (the K-016 allows the use of longer-ranged Kh-55SM missiles); in other words, only the aircraft manufactured from 1986 onwards are modernised. In total, this represents a fleet of between 30 and 35 aircraft. The program is divided into two steps: the first one consists of making the aircraft compatible with Kh-101/102 cruise missiles. These are too big to fit in the internal missile bay; hence, new external hardpoints are added. A total of eight Kh-101/102s can be carried under four double missile pylons, in addition to six Kh-55/55SM/555s in the internal rotary missile launcher. Several pieces of equipment are also replaced in this first step of the modernisation, including the satellite signal reception system, the instrument landing system, and other navigation systems. The first Tu-95 modernized to carry the Kh-101/102 missiles was the Tu-95MS Saratov, rolled out at the Beriev aircraft plant in Taganrog in early 2015. It was transferred to the Russian Air Force in March 2015. Since 2015, the serial modernisation is carried out also by the Aviakor aircraft plant in Samara at a rate of three aircraft per year. The first Tu-95 modernized by Aviakor was the Tu-95MS Dubna, transferred to the Russian Air Force on 18 November 2015. In the future, Tu-95MSs are to be upgraded with the SVP-24 sighting and computing system from the Russian company
