![]() ![]() Korea’s Hanjin Shipyard successfully initiated the main engines and inflated the bags within the skirting system on LSF-II Craft 633 for the first time December 9, 2022. The first two C4N systems were completed and delivered in mid-2022. The Panama City C4N system team has provided onsite subject matter expertise to support HJSC with installation, software integration, and startup of the C4N systems since April 2022. Initial component deliveries started in early 2021, while Hanjin Shipbuilding and Construction (HJSC) was still constructing the craft at Yeongdo Shipyard in Busan, ROK. Even with an established Navy baseline, this extensive work required the USN and ROK teams work together to find and track all the changes needed to make the C4N system fit and operate within the LSF-II. The team also developed LSF-II- specific craft drawings. In April 2019, the NSWC PCD team used the mature baseline of the USN’s LCAC C4N system to begin redesigning a C4N system for the LSF-II craft.įor the ROK variant, the NSWC PCD C4N system team remapped the communication links between the craft’s subsystems and the C4N system, and then modified all of the software to accept and process the inputs. Navy LCAC, the modified C4N system was feasible from a technical perspective. Due to similarities between the ROK Navy LSF-II and the U.S. ROK’s Defense Acquisition Program Administration (DAPA) first requested modified Navy C4N systems for LSF-II craft 633 and 634, funded under FMS case KS-P-GRL, from the NAVSEA International Fleet Support Program Office in 2018. NSWC PCD personnel helped modify the Navy’s LCAC Command, Control, Communication, Computers, and Navigation (C4N) System for use on ROK’s domestically produced LSF-II. As first-in-class for the LSF-II, crafts 633 and 634 serve as prototypes of the redesigned LSF concept a total fleet of 18 LSF-IIs is planned. LSF-II crafts 633 and 634 will join two earlier LSFs already in service with the ROK Navy. The LSF-II is a 90-metric ton hovercraft with a top speed of 40 knots.
