Low-Cost Guided Imaging Rocket

The Low-Cost Guided Imaging Rocket is a weapons system under development for the US Navy in a joint program with South Korea. The program aims to provide a precision guided 2.75 inch (70 mm) rocket for use with existing Hydra 70 systems in service, as such it has many similarities with the Advanced Precision Kill Weapon System program. The principal difference between the systems is that while APKWS would use terminal laser homing, requiring the target to be 'painted' until impact, LOGIR would home on an image supplied by the launching aircraft, making it possibly less accurate against moving targets, but also a true fire-and-forget weapon.

Development
South Korea's contribution in the LOGIR program are the following:
 * Electronics for guidance and control system
 * Electronics for control actuation system (DSP and PWM inverter board)
 * Assembly parts for control actuation system (CAS frame and integrated BLDC motor)
 * Airframe structure and fins (canard fin, CAS skin, seeker skin)
 * Cruciform tail fins and nozzle assembly
 * Warhead and fuze attachment improvement

Specifications

 * Diameter: 70 mm
 * Guidance: INS midcourse/Imaging infrared terminal.
 * Motor: Existing Hydra 70 motors
