The NATO Sea Sparrow Missile is a U.S.-origin radar-guided surface-to-air missile based on the AIM-7 Sparrow, fielded for ship self-defense through MK 57 NSSMS, MK 29, and vertical-launch installations. It later gained a ground-launch conflict role when RIM-7 missiles were committed to Ukraine for air defense and integrated into Buk-based FrankenSAM systems.
The United States committed RIM-7 missiles for Ukraine's air defense in January 2023; USNI identified them as Sea Sparrow missiles for use with Ukrainian Buk systems, and later reporting described the Buk-based FrankenSAM branch as built around AIM-7/RIM-7 Sea Sparrow missiles.

RIM-7 Sea Sparrow designations track the ship-launched branch of the Sparrow family. Early Sea Sparrow variants adapted AIM-7 bodies for naval launchers, while the later RIM-7M/P branch led into the separate RIM-162 Evolved Sea Sparrow Missile family.
