Low-Cost Guided Imaging Rocket
Encyclopedia
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.
South Korea
The Republic of Korea , , is a sovereign state in East Asia, located on the southern portion of the Korean Peninsula. It is neighbored by the People's Republic of China to the west, Japan to the east, North Korea to the north, and the East China Sea and Republic of China to the south...

Fire-and-forget
Fire-and-forget is a third-generation method of missile guidance. The military uses the term for a type of missile which does not require further guidance after launch such as illumination of the target or wire guidance , and can hit its target without the launcher being in line-of-sight of the...

Development
South Korea's contribution in the LOGIR program are the following:- Electronics for guidance and controlGuidance systemA guidance system is a device or group of devices used to navigate a ship, aircraft, missile, rocket, satellite, or other craft. Typically, this refers to a system that navigates without direct or continuous human 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 infraredInfrared homingInfrared homing refers to a passive missile guidance system which uses the emission from a target of electromagnetic radiation in the infrared part of the spectrum to track and follow it. Missiles which use infrared seeking are often referred to as "heat-seekers", since infrared is just below the...
