Naval News recently did a post highlighting a 4th Fleet live fire test combining a Korean developed fire and forget guided rocket system with the Common Uncrewed Surface Vessel (CUSV) cued to a target by a Radiosonde UAS for a fully uncrewed kill chain.
The “Poniard” Korean-Low cOst Guided Imaging Rocket (K-LOGIR) is closely related to the APKWS, both being based on the 70mm Hydra unguided rocket. Unlike the semi-active laser homing APKWS, the K-LOGIR is a fire-and-forget system allowing multiple simultaneous engagements.
Most of the reports I have read on this exercise are unclear if six missiles hit a single target or if six missiles hit six different targets, but this Defense Mirror report, “Textron’s Unmanned Boat Uses South Korean Weapon to Engage Multiple Targets.” makes it clear that multiple targets were engaged in a single salvo.
I don’t fully understand how they designate different targets for the missiles in the salvo, but it may be that they are sending them to different waypoints before they initiate their search.
The ability to engage several targets simultaneously makes this system attractive for countering surface swarm tactics like those that might be encountered by PATFORSWA, but for the Ports, Waterways, and Coastal Security mission, the APKWS’ semi-active laser homing might be a better solution, in that we are unlikely to have to engage numerous targets in a single salvo and we may want to target particular parts of an adversary’s vessel or perhaps engage low-level air targets such as UAS, helicopters, or general aviation aircraft. Presumably, APKS could be fired from the same launcher.
Take a look at the launcher above and below. Here it is mounted on an unmanned 39-foot boat. In the photo above you can see that it traverses and elevates. It appears to hold up to six rockets. It might be an appropriate way to arm Coast Guard patrol boats and larger cutters with APKWS, but “Vampire” might be even simpler.

I would really like to see 4th Fleet make more effort to publicize their experimentation efforts. I’m surprised I was not able to find a YouTube video that documented this test and I have seen no mention of it on the 4th Fleet website.
I am also curious to know if the Navy’s 39′ CUSV could be operated from the stern ramp of a National Security Cutter. Interoperability?
