SIPRI reports that Pakistan has received 50 (out of 100 ordered) LD-10 anti-radiation missiles from China in 2014 and 2015. These missiles were ordered in 2011.
The LD-10 air-to-surface anti-radiation missile is a variant of the SD-10A missile meant for Suppression of Enemy Air Defenses (SEAD), similar to Raytheon’s High-speed Anti-Radiation Missile (HARM). The LD-10 retains the overall aerodynamic layout of the SD-10A, but has the active radar seeker of the SD-10A replaced with a new passive radar-homing seeker.
The LD-10 has been designed such as to be retrofitted faster and with minimal modifications to launch platforms, which have been cleared for use with the SD-10A missile. These include the J-8, J-10, J-11 and the JF-17. The missile was marketed with a maximum range of 80 km with a 20 kg warhead.
