Russia’s KTRV brings to the fore some powerful cruise missiles

Prasun K. Sengupta

Russia’s Tactical Missiles Corp (KTRV) is no stranger to India, having supplied several types of guided-weapons developed by the Raduga and Novator design bureaux to the Indian Air Force (IAF) and Indian Navy (IN) since 1970.

The Raduga Kh-59MK2 stealthy cruise missile is 4.2 metres long, has a wingspan of 2.5 metres, and a 0.4-metre x 0.4-metre cross-section with its wings and fins folded. Meant for use against a variety of static ground targets, it is powered by a NPO Saturn-supplied 50MT turbofan for export and has a maximum engagement envelope of 290km. The missile incorporates a ring laser gyro-based inertial navigation system (RLG-INS) that is coupled to a GPS receiver, plus an optronic terminal guidance seeker that gives a circular error probable (CEP) of 3 metres by either day or night. One or more missions can be loaded into the missile’s on-board mission computer to provide optional guidance on different targets. The missile can fly as low as 50 metres over the ground, with warhead options including a 310kg blast penetrator or sub-munitions.

KTRV’s 600kg Grom-E1 cruise missile and 450kg Grom-E2 gliding weapon have a unified design configuration with swept-back wings. Both also feature the same combined RLG-INS/GPS guidance system, and differ in that while the powered Grom-E1 comes equipped with a rear-mounted rocket propulsion system, the gliding Grom-E2 uses this space for an additional high-explosive warhead instead of the rocket engine. The Grom-E1 has a 300kg warhead, while the Grom-E2 has a 200kg warhead. Both these PGMs are meant for use against static land targets.

The Raduga Kh-58UShK anti-radiation missile, featuring IIR terminal guidance seekers, is optimised for destroying air-defence radars that are operating in pulse-mode and that turn off when the missile is in its terminal phase. The missile weighs 650kg, is 4.19 metres long, has a wingspan of 0.8 metres, a body diameter of 0.38 metres, a range of up to 245km, is designed to hit within a radius of 10 metres of its target and has a 149kg warhead. The Kh-58UShK has folding wings, can be used by MiG-29K, MiG-29UPG and Su-30MKI combat aircraft, and has been designed to both hit pre-programmed radar targets and targets detected by high-accuracy pod-mounted direction finders like the Defence Research Development Organisation (DRDO)-developed SIVA system. The missile has an innovative broadband passive radar seeker working in the 1.2 GHz-11 GHz frequency range to seek out hostile radars.

The Kh-35UE anti-ship cruise missile is the latest iteration of the Kh-35 (presently arming the three Project 15 Delhi-class destroyers, four Project 25A Kora-class corvettes and three 1241.1 Tarantul-1 corvettes), whose development began in the former USSR in March 1983. The Kh-35UE is a 550kg (1,213lb) subsonic anti-ship cruise missile that has been adapted for ship-, shore-, helicopter-, and aircraft-launched applications. While the outer-mould line remains the same as the earlier models, the newer version is powered by a smaller and lighter Saturn Izdeliye 64M turbofan (allowing for more fuel, and a doubling of range to 260km). The Kh-35UE is presently arming the Indian Navy’s MiG-29Ks and the IAF’s upgraded MiG-29IPGs.
