I think they would be deployed by both fleet elements and Stations.
the hull of the Recon ship would be covered in Metamaterials which absorb radtion across the EM band, both for protection and stealth capablity's. allow the Dagon to Enter areas normaly prohibited and do deep scans.
the larger drives are give it longer ranges and faster speeds than the Standard Viper or shuttle. and with the modular capability it can be fitted for limited combat missions as well.
just a few ideas bouncing around in my head at anyrate LOL.
