This design is classed as a Military Vessel for maintenance purposes
This design is classed as a Scout for auto-assignment purposes
Only 2,662 tons, and with a 90% cloaking device the RADAR signature is reduced to only 267 tons... the same as a Fighter. Carries large passive sensors.
Moves at 8,266 kps. The fastest Galapagonian that we've observed moved at just under 7,800 kps.
The thermal sensor is from the freaking 1970s. Perhaps we should delay just a few months to upgrade our thermal imaging tech.
If we replaced those off-the-shelf sensors with slightly smaller ones, we could increase the fuel endurance.
