NS is said to be working on a development of the Alpha 121A Nano Fighting Ship. This is said to be a three man space fighter with superluminal capabilities. Although the ship will be equipped with TPMs and a full suite of combat systems it will be designed to cheap (relatively) to build and operate. NS thus could build a large fleet for the same cost of a small cost of full size warships.
The ship could also be operated in unmanned mode though NS say this will be mostly used for ferrying and routine patrols. NS will decide whether to go ahead with this new project later in the year.
