HQ-16 Air Defense System

Full Specifications

HQ-16 Medium-Range Air Defense System

The HQ-16 (Hong Qi-16, NATO: CH-SA-16), also known as the LY-80 for export, serves as a cornerstone of China’s integrated air defense network. Developed to bridge gaps between short-range systems like the HQ-17 and long-range assets such as the HQ-9, this mobile surface-to-air missile (SAM) system provides robust protection for ground forces, airbases, and high-value assets against a wide array of aerial threats, including fighter aircraft, helicopters, cruise missiles, UAVs, and short-range ballistic missiles.

Manufacturer and Origin

The system was developed by the Shanghai Academy of Spaceflight Technology (SAST), part of the China Aerospace Science and Technology Corporation (CASC). It draws design heritage from the Russian Buk series (SA-11/SA-17) but incorporates significant Chinese advancements, including vertical cold launch technology. It entered service with the People’s Liberation Army (PLA) around 2011 and has been exported, notably to Pakistan as the LY-80.

Key Capabilities

The HQ-16 uses a transporter-erector-launcher (TEL) configuration, typically with six vertical launch cells per vehicle. Missiles employ semi-active radar homing with inertial guidance, enabling effective engagement in electronic warfare environments. Later variants (HQ-16B/C) extend performance significantly. It operates in all-weather conditions and supports networked, multi-layered defense architectures.

Speed and Range

Base HQ-16/HQ-16A models offer a slant range of approximately 40 km, while upgraded HQ-16B/C variants reach 70 km. Advanced iterations like the HQ-16FE push capabilities to around 160 km. Missiles achieve speeds exceeding Mach 3 (up to Mach 4 in some reports), with engagement altitudes from very low level (~15 m) up to 18-27 km depending on the variant. Radar systems include S-band 3D phased-array detection out to ~140 km and L-band support, allowing a battery to detect up to 144 targets and track dozens simultaneously.

Cost/Price

Exact figures are classified, but estimates place a battery or system unit in the $30-50 million range, making it relatively cost-effective compared to Western peers due to cold-launch efficiency and domestic production. Full procurements, such as Pakistan’s initial batches, reflect competitive export pricing for medium-range SAMs.

In operational use, the HQ-16 enhances China’s A2/AD strategy and provides allies with credible medium-tier air defense. Its mobility on 6×6 vehicles ensures rapid deployment, while vertical launch supports 360-degree coverage without repositioning.
