PorSav is also called “Native MANPADS”, “HİSAR Portable” and “National Portable Air Defense Missile”. Currently, the Turkish armed forces use FIM-92 Stinger MANPADS but they will gradually replace them with locally-made PorSav (Portable Defense). The design of both missile systems is almost identical.

The Turkish engineers of two companies - Roketsan and Aselsan – managed to keep the Stinger’s major features. The Turkish missile will also hit the target within 4 km at a maximum range of 6 km. Turkish specialists have created a new product based on the technology that American engineers used when creating HISAR and Stinger MANPADS. PorSav's main advantage is that it will use the Imager Infrared (IIR) Seeker Head instead of the Infrared (IR) Seeker Head, which is also used in the Stinger Missile. IR Guided Missiles can be easily deceived by countermeasure systems called "Flare" since they focus on the high heat emitting region. IIR Guided Missiles, on the other hand, are very difficult to be deceived by countermeasure systems since they are locked on the target thanks to the "viewer" system. It is estimated that an IIR Title similar to the IIR Title used in the HİSAR project will be used in the PorSav Missile.
