The HİSAR Air Defense Missile Family represents a critical milestone in Türkiye’s effort to establish an indigenous and layered air defense capability. Developed to counter low- and medium-altitude aerial threats, HİSAR systems are optimized to neutralize cruise missiles, UAVs, attack helicopters, fixed-wing aircraft, and air-to-surface munitions.

Operational Purpose and Role

HİSAR-A and HİSAR-O are designed to protect:

• Military bases and forward operating positions
• Radar sites and air defense nodes
• Logistics hubs and strategic infrastructure
• Maneuvering ground forces

Within Türkiye’s layered air defense doctrine:

• Very short range: gun-based systems (e.g., KORKUT)
• Low altitude: HİSAR-A
• Medium altitude: HİSAR-O
• Long range / high altitude: SİPER

HİSAR systems are positioned as tactical-to-operational level air defense assets.

Doctrine and Concept of Operations

HİSAR systems are designed in accordance with network-centric warfare principles. While capable of operating autonomously as a battery, they are fully interoperable with higher-level command and control networks.

A typical HİSAR battery includes:

• Missile launch vehicles
• 3D search radar
• Electro-optical sensor systems
• Fire control radar
• Command and control vehicle

The engagement sequence typically follows:

• Target detection via radar
• Identification and tracking
• Engagement decision
• Vertical missile launch
• Mid-course update via data link
• Terminal homing using IIR seeker

The use of a passive IIR seeker in the terminal phase enhances resistance against electronic warfare and radar jamming.

System Architecture

The HİSAR family features a modular architecture and can be integrated onto wheeled or tracked platforms. Major subsystems are domestically developed.

Key components:

• Dual-pulse solid rocket motor
• Thrust vector control system
• Inertial Navigation System (INS)
• One-way data link
• Imaging Infrared (IIR) seeker
• High-explosive fragmentation warhead
• Proximity and impact fuse

Radar integration is supported through national 3D AESA-based search radars. Specific radar band and detection range values are not publicly disclosed.

Survivability and Protection

HİSAR systems are mobile and capable of rapid deployment and redeployment, which enhances survivability against Suppression and Destruction of Enemy Air Defense (SEAD/DEAD) operations.

Key survivability features:

• Vertical launch with 360° engagement envelope
• Distributed deployment capability
• Mobility-based survivability
• Reduced radar dependency in terminal phase

Advantages Against Modern Threats

• Effective against low-RCS targets such as UAVs
• Capable of intercepting cruise missiles
• High maneuverability via dual-pulse motor
• Enhanced ECCM resilience due to passive terminal guidance

Limitations

• Not designed for ballistic missile defense
• Limited engagement range compared to long-range systems such as Patriot or S-400
• Primarily optimized for low- and medium-altitude targets

Detailed Technical Specifications

Dimensions and Weight

Exact missile dimensions and total system weight are not fully disclosed in open sources.

Propulsion System

• Dual-pulse solid rocket motor
