NS is to give it's Pentekonter minesweeping and training fleet of ships it's first major overhaul starting this year. Pentekonter Intermediate Life Update 2125 will include updates which were planned for way back in 2120 but never took place due to the war and other upheavals. Ships did receive heavy overhaul however, to remove worn components and check for fatigue.
The upgrade will include re-engining the fleet with a Proton RM-01 e-Core engine (as is used in export Pentekonters and the patrol developments), the legacy SPECNES minesweeping suite will be removed, it has already been replaced by the newer DMS system though the older system has not yet been taken out of the ships. The space saved, and electrical bandwidth released, will allow for an eight cell TPM-VLS system to be fitted.
The first two ships have already begun their upgrades and are expected to be completed by March, the whole fleet will take the rest of the year at least.
