The SD-10A is the export designation of the PL-12 Air-to-Air missile developed by Luoyang Electro-Optical Technology Development Center. The SD-10A is an active radar Beyond Visual Range Air-to-Air Missile (BVRAAM). It has the ability to turn off its active radar seeker and passively home in on electronic emissions (Home-On-Jam).
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.
A further development of the SD-10A is the DK-10. The DK-10 is heavily modified for use as a Surface-to-Air Missile (SAM) as reported earlier.
