“An improved version, designated R-73RDM2, has an up-rated rocket motor giving twice the range and seeker sensitivity of the earlier model under typical combat conditions. It can also be fired rearward to protect the rear hemisphere of the launching aircraft. It has a 90ยบ off-boresight capability, re-programmable digital control electronics, a better resistance to IR counter-measures and the capability to engage low-flying targets. The integrated counter-countermeasures (ICCM) combines four different techniques and has an algorithm that will allow the missile to shift its aim from the engine of a targeted aircraft to the middle of the airframe in the final milliseconds of an intercept. The R-73RDM2 has a range of 40 km and a maximum speed of Mach 4.”
Is this information true? And, what’s the designation of the R-73 fitted with additional rocket booster section for backward operation?
