New Sparta have drastically reduced the size of the order for the Corkscrew 051A Medium Combat Ship from 59 to 25 (of which 11 are currently in service). Instead of a single fleet NS will instead build the type in batches that develop and improve over time as has happened with the Type 035 (which has been built as the Panther, Indy and latterly the Kinetic) and Type 041.
At current rate the remaining ships will be built by the end of the decade, after that there will be a second batch of around 20 ships currently known as the Type 051X which will have "design and conceptual differences".
