The LY-80N is a modern, vertically launched, medium-range surface-to-air missile (SAM) system designed to provide comprehensive air defense for naval vessels against a wide spectrum of aerial threats — including high-speed fighter aircraft, anti-ship cruise missiles (ASCMs), UAVs, precision-guided munitions, and tactical ballistic missiles (TBMs) in their terminal phase. As the naval variant of the land-based LY-80 series, the LY-80N integrates advanced active radar homing missiles, a high-performance AESA fire control radar, and a compact vertical launch system (VLS) to deliver layered protection for frigates, corvettes, and destroyers in contested maritime environments.
Engineered for high reliability, rapid reaction, and seamless integration with modern combat management systems (CMS), the LY-80N is a key component of contemporary naval integrated air and missile defense (IAMD) architectures. It supports both autonomous operation and network-centric warfare, enabling coordinated engagement across fleet assets.
Key Features
- Vertical Launch System (VLS): 32-cell compact hot-launch VLS (H/AJK-01), compatible with hot and cold launch modes, enabling 360° coverage and rapid salvo firing.
- Active Radar Homing (ARH) Missiles: “Fire-and-forget” capability with mid-course datalink and terminal active guidance for high kill probability.
- Dual-Band AESA Fire Control Radar: One X-band and one S-band AESA radar unit (3D-TR) for precision tracking, multi-target engagement, and superior electronic counter-countermeasures (ECCM) performance.
- Multi-Target Engagement: Simultaneously guides missiles to up to 4 targets, while tracking over 40 aerial tracks.
- High Reaction Speed: From detection to launch in under 6 seconds.
- All-Weather, Full-Sea-State Operation: Designed for operation in harsh maritime environments (salt fog, humidity, shock, vibration).
- Network-Centric Warfare Ready: Fully interoperable with shipborne CMS, radar suites, electronic warfare systems, and off-board sensors (e.g., helicopter, UAV cueing).
- Compact & Modular Design: Optimized for integration on medium-displacement vessels (1,500–6,000 tons).
- Ballistic Missile Defense (BMD) Capability: Capable of intercepting short-range TBMs in terminal phase.

Operational Roles
- Area Air Defense: Protects naval task groups and high-value units (e.g., carriers, supply ships).
- Anti-Cruise Missile Defense: Engages sea-skimming ASCMs with high-speed maneuverability and precision tracking.
- Fleet Escort: Provides air cover for amphibious groups, logistics convoys, and patrol vessels.
- Ballistic Missile Defense (BMD): Terminal-phase interception of short-range ballistic threats.
- Networked Fleet Defense: Shares track data and receives cueing from AEW aircraft, over-the-horizon radars, or allied ships.
- Electronic Warfare Resilience: Operates effectively in high-jamming environments using LPI radar modes and frequency agility.
