The Spearfish Missile is a subsonic, precision-guided anti-ship missile designed for versatility and reliability in maritime strike operations. Introduced in 1978, it remains a critical component of naval warfare, capable of engaging a variety of surface targets in contested environments. With its focus on cost-effectiveness and adaptability, the Spearfish has been widely adopted by naval forces for its proven track record and operational flexibility.
The Spearfish missile’s design emphasizes simplicity and effectiveness, utilizing advanced guidance systems and a robust propulsion unit to ensure accuracy and dependability. The missile’s compact size and lightweight construction make it compatible with a wide range of launch platforms, including surface ships, submarines, fixed-wing aircraft, and ground-based systems. This multi-platform capability allows it to integrate seamlessly into diverse naval strategies.
One of the key features of the Spearfish is its mid-range capability, designed to engage enemy vessels from a standoff distance. Its sea-skimming flight profile reduces radar visibility, allowing it to approach targets undetected until the final engagement phase. This approach ensures a high probability of mission success even in environments with advanced enemy defenses.
Design and development

The Spearfish Missile System features a streamlined design focused on subsonic maritime strike capabilities. Constructed from lightweight, corrosion-resistant materials, the missile is designed to withstand harsh maritime environments. Its aerodynamic shape and low radar cross-section enhance its stealth characteristics, ensuring survivability against advanced detection systems.
At 3.84 meters (12.6 feet) in length and 0.34 meters (13.5 inches) in diameter, the Spearfish is compact enough to be deployed from a variety of platforms. Its folded wingspan of 0.91 meters (3 feet) allows for efficient storage in standard launch canisters, while the unfolded wings provide stability and maneuverability during flight.
The missile’s propulsion system consists of a turbojet engine paired with a solid-fuel booster for initial launch. This configuration enables the Spearfish to achieve a cruising speed of approximately 855 km/h (531 mph), making it ideal for engaging targets within its operational range of 124 kilometers (67 nautical miles). The solid-fuel booster ensures rapid acceleration upon launch, while the turbojet provides sustained thrust throughout the missile’s flight.
Guidance is a critical component of the Spearfish’s design. The missile employs a combination of inertial navigation and active radar homing for mid-course and terminal guidance. The active radar seeker allows the missile to track and engage moving targets with precision, while the inertial navigation system ensures accurate mid-course corrections, even in GPS-denied environments.
The warhead of the Spearfish is a 221-kilogram (487-pound) blast fragmentation design, optimized for maximum damage against naval vessels. The warhead’s delayed-action fuse ensures penetration of the target’s outer hull before detonation, maximizing the destructive force delivered to critical systems such as propulsion, command centers, and weapons magazines.
The Spearfish’s sea-skimming flight profile is a defining feature of its design. By flying at extremely low altitudes, the missile minimizes its radar signature and reduces the likelihood of detection. This approach also allows the Spearfish to exploit gaps in enemy radar coverage, increasing its survivability in contested environments.
One of the missile’s standout features is its modular construction, which allows for easy upgrades and maintenance. The Spearfish’s systems can be updated with minimal logistical overhead, ensuring that the missile remains effective against evolving threats. This modularity also enables operators to tailor the missile’s capabilities to specific mission requirements.
The Spearfish is compatible with a variety of launch platforms, including quad-launch systems on surface ships, torpedo tubes on submarines, and wing-mounted racks on aircraft. This versatility ensures that the missile can be deployed across multiple domains, enhancing its strategic utility.
Maintenance and logistics have been streamlined to support the Spearfish’s operational lifecycle. The missile’s durable construction and modular design minimize the need for frequent repairs, while its compatibility with standard storage and transport systems simplifies logistical operations.
The Spearfish Missile System’s design reflects a balance of cost-effectiveness, adaptability, and lethality. Its proven performance and ongoing modernization efforts have ensured its place as a key asset in naval operations worldwide, capable of addressing the challenges of modern maritime warfare.
