looks like other than the proven 36MT engine license manufacture, we also funded or picked up the propfan work lying around
KH 101 / 102

Details of the Kh-101 remained shrouded in secrecy for many years,
but one of the most intriguing facts to emerge was that its designers had planned to use a propfan engine to power the missile, in place of a conventional small turbofan. This engine, the Soyuz/Moscow R128-300, was rated at 1,300 hp for launch/boost and at 500 hp for the cruise phase. Mounted on the rear section of the missile, behind the tail unit, it drove two sets of three, curved contra-rotating props. It is believed that the early prototypes of the Kh-101 were flown with the propfan engine, but that its performance fell short of requirements. Instead, an 'interim' Kh-101 design was drawn up to use a podded OMKB/Omsk TRDD-50AT (izdieliye 36MT) turbofan, which entered series production in 2002 at Rybinsk. The same engine is used to power the Kh-555 strategic cruise missile, plus the improved Kh-35 and Kh-59M missiles. It is unclear whether work is continuing on the propfan-powered
The Kh-101 is 7.45 m in length, has a launch weight of between 2,200 and 2,400 kg and cruises at a speed of 684 to 720 km/h. It has a maximum range of 5,000 to 5,500 km.
The missile is built largely from composite materials and has been specifically engineered to have a very low radar cross-section - quoted as 0.01 m². The Kh-101 uses a combination of Electro-Optical (EO) terrain-referenced navigation (like the Kh-55) for mid-course guidance, plus an EO-seeker with target recognition capability for terminal homing. The Kh-101 has not been credited with a satellite or INS navigation option, but there is no reason why these options should not be available to it. The Kh-101 is armed with a 400 kg high-explosive/penetrating warhead and is geared for use against large infrastructure targets.
After launch, the Kh-101 has a typical cruise altitude of 30 to 70 m, although the missile can fly at altitudes of 6,000 m.
A programme to develop a smaller, medium-range conventional cruise missile, similar to the Kh-101, has been identified as the Kh-SD (srednei dalnosti - medium-range). This missile is believed to share the same navigation and guidance system as the Kh-101, and may be optimised to fly at lower penetration heights with the option of either a unitary or submunition warhead. The Kh-101 and the Kh-SD may also share the same Sigma mission planning system. The status of the Kh-SD is unclear and it is unlikely to appear until well after the Kh-101 is established in service.
