Full Specifications

RIM-7 Sea Sparrow Naval Air Defense Missile

The Sea Sparrow missile is a widely deployed naval air defense system designed to protect warships from incoming aerial threats, including anti-ship missiles and aircraft. Originally developed during the Cold War, it has evolved into a highly reliable close-in and medium-range defense solution used by NATO and allied navies. Its compact design allows integration on a wide range of surface combatants, from frigates to aircraft carriers. The missile’s rapid response capability and proven combat record make it a key layer in modern naval defense architectures.

Manufacturer

The Sea Sparrow program is managed by the NATO Sea Sparrow Consortium, with primary manufacturing led by Raytheon in the United States. It represents a collaborative effort among multiple allied nations, ensuring interoperability and shared technological upgrades. The latest evolution, the Evolved Sea Sparrow Missile (ESSM), significantly enhances range, maneuverability, and resistance to electronic countermeasures.

Speed and Range

The RIM-7 Sea Sparrow achieves speeds of approximately Mach 2.5, allowing it to intercept fast-moving threats effectively. Early variants offer a range of around 15 to 20 km, while newer ESSM variants extend engagement ranges beyond 50 km. The missile uses semi-active radar homing, requiring continuous target illumination from the launching platform.

Cost / Price

Unit costs vary by variant. Earlier RIM-7 models are estimated at around $165,000 to $300,000 per missile, while advanced ESSM variants can exceed $1 million per unit due to improved guidance systems and extended range capabilities.
