Russian-Ukrainian front line, Ukrainian soldiers dismantled a failed U.S.-made "Stinger" portable air defense missile, which had no possibility of repair, as it was a single-use weapon. After the missile was launched, the launcher completed its mission. It was not designed to be reloaded with another missile under battlefield conditions. Its internal circuitry and mechanical structure were optimized for a single launch.
The missile's battery cooling unit (BCU) is a critical component. The BCU is a disposable battery and gas generator that powers the missile's seeker and injects coolant (argon) into the infrared seeker before launch, enabling it to "see" targets with thermal radiation characteristics. A new BCU must be used for each launch, which fundamentally determines the single-use nature of the missile system. Because once the system is activated, the BCU is depleted.
