Raduga Kh-65 / Kh-SD
Russian President Boris Yeltsin announced in January 1992 that he would end the manufacture of all sea- and air- launched cruise missiles.
The Kh-65 missile is a tactical modification of the strategic Kh-55. According to available information (on data sheets at the 1992 Moscow Air Show), its range was to be 500-600 km. The reduced range is a product of compliance with the SALT-2 treaty. The reason for shortening its range was that, according to terms of the SALT-2 Treaty, any aircraft carrying missiles with a range longer than 600 km will be regarded as a strategic one and the number of such aircraft is strictly limited.
A full-sized version of the Kh-65SE was displayed for the first time in 1993 (February in Abu Dabi, then September 1993 in Zhukovskiy and Nizhniy Novgorod). The missiles shown at the exhibitions did not differ from the earlier versions except for their range, quoted as 250 km when launched from low altitude and 280 km when launched from high altitude.
The Kh-65 was intended for use against large targets with a larger than 300 m2 effective reflecting surface area, particularly warships, under conditions of strong electronic interference. It approaches the target guided by an inertial navigation system while flying at a low altitude. Having reached the region where the target is located, it rises to a higher altitude and its active-radar target seeking system turns on.
The Kh-65SE derivative of Kh-65 cruise missile is a long range, aircraft-launched anti-ship missile. It employes an active radar seeker for the terminal phase of the flight engagement.
Kh-101 components were to be used in Kh-SD medium range ALCM in development in the 1990s. The Kh-SD is a tactical version of the Kh-101, with shorter range and a heavier warload, which may be either a penetrator or a cluster-munition. The Kh-SD may be an improved version of the Kh-65 precision-attack cruise missile, which was promoted by the Russians in the early 1990s, along with a "Kh-65E" antiship variant.
The Kh-SD is reportedly a smaller version of the Kh-101. It is said to be shorter and lighter [by some 600-800kg], with a much shorter range of only several hundred kilometers. It likely uses the same homing system as the Kh-101, but the Kh-65S anti-ship version may have an active radar seeker. The fact of the existence of this program was first disclosed in data sheets released at the 1992 Moscow Air Show, at which time it appeared to be a tactical derivative of the Kh-55 Granat [AS-15 Kent] strategic cruise missile. More recently, it is described as the short range tactical version of the Kh-101.
