Unlike the Type 90 guided missile, the AAM-5 does not have canard control surfaces, using thrust vectoring for high agility. The missile body has narrow strakes extending over most of its length. It features inertial guidance, provided by a fiber-optic gyroscope, which allows for LOAL (Lock-on after launch). Additionally it allows for high off-boresight use, through cueing targets outside of the seeker's field of view via a HMD. Terminal homing is via infrared imaging (IIR). In terms of generation, it is placed in the same generation as missiles such as the AIM-9X and IRIS-T. For the AAM-5B, the NEC manufactured seeker has also been improved, with a dual wavelength infra-red focal plane array seeker. Additionally the gimbal type was changed from a 2-axis to a 3-axis design, allowing for improved off-boresight capabilities, as well as improved IRCCM. The reason the additional gimbal improves IRCCM functionality is due to the missile's IRCCM method, an image recognition type which relies on comparing the frame to prior ones to look for the target which it was originally locked onto.

• AAM-5 • The original variant introduced in 2004, has limited operational time due to its seeker cooling type. • AAM-5B • Enhanced background discrimination capability and IRCCM by changing to a dual wavelength seeker and a 3-axis gimbal. Seeker cooling time is extended by the adoption of a Stirling engine, up to a maximum cooling time of 1 hours.
