U39013551: /* Survivability and armour */ It can't survive multiple hits from a stinger. It's rather arbitrary because any kind of "real" hit from a missile will pretty much make the Su-25s inoperable.

 <!-- ''Describe how the aircraft behaves in the air. Speed, manoeuvrability, acceleration and allowable loads - these are the most important characteristics of the vehicle.'' -->
 The Su-39's flight performance is nothing remarkable, particularly when it comes to combat scenarios where agility and responsiveness are paramount. Its design, characterized by sleek swept wings, ensures exceptional manoeuvrability, enabling precise and rapid in-flight adjustments. This agility is especially evident in its high-G manoeuvres, allowing the aircraft to execute evasive actions and engage targets with unparalleled precision even in dynamic and challenging environments. In combat, the Su-39's twin-engine configuration provides robust thrust, resulting in impressive acceleration and climb rates. This power-to-weight advantage not only facilitates swift engagement but also enables rapid altitude changes, a critical asset in maintaining the element of surprise and evading hostile threats. While the Su-39 excels in various aspects of ground attack and combat manoeuvrability, it's worth noting that it operates within a subsonic flight regime, resulting in a comparatively lower maximum speed. This subsonic characteristic, while not detracting from its overall combat effectiveness and versatility, does place certain limitations on its ability to rapidly cover vast distances.

-The Su-39's cockpit design prioritizes pilot survivability. By effectively attenuating and dispersing the damage, the anti-fragmentation armour significantly reduces the risk of damage to critical components, thus enhancing the aircraft's overall survivability. The aircraft's adept countermeasures system incorporates effective neutralization of threats by disrupting enemy radar and missile guidance systems. Notably, the inclusion of an Infrared Countermeasure (IRCM) system significantly enhances defense capabilities, emitting controlled infrared energy to deter and divert heat-seeking missiles. The Su-39 is able to withstand multiple hits from FIM-92K Stinger missiles and low-medium calibre munitions, solidifying its robust survivability profile while ensuring effective ground-strike mission execution and pilot safety.
