Viceroy Caratore, in a New Year Eve address, has revealed that NS is working with the MBO on a "major new type of warship". No other details were given about this apart from the fact it is to be the Type 126. This indicates it will be either unmanned or a small combatant.
The latter may be a clue to the new ship. Work on the Alpha 121A Nano Fighting Ship ended a few years ago but NS Research continued development of automation technologies and two of the Alphas have been trialing some new (and secret) systems over the last year.
Whatever Type 126 turns out to be it should be revealed later this year according to the Viceroy.
