Polaris

The RSI Polaris is a ship in the concept stage and will be filling the void between larger capital sized ships and non-capital ships that had been created when the original Idris grew in size significantly during production. At the length of around 110 meters the Polaris will be a Corvette. It has been mentioned that it will have a military focus.

Developer Comments
It was said in 10 FTC episode 77 (question 9, 29 Feb 2016) that Corvettes will fill a role between capital and sub-capital ships. As such, the Polaris will be more economical in their role. It won't be a massive carrier but will feature the ability to dock a ship and hold its own while fighting fighters or bigger ships. It was also said that a group of Corvettes could cause problems for bigger ships such as a frigate or a destroyer.

During Bensday with Batgirl & Ben episode 45 (9 Mar 2016), Ben Lesnick commented that they were leaning towards a length of 100 to 120 meters.

Speculation
Several sources have hinted that the Polaris will most likely become available during Citizencon 2016.
