The brochure says the Ares is being "designed to be scrambled from an orbiting carrier or ground base." Does this mean that the Ares can be launched from a Polaris, 890 Jump, Idris, Javelin, or Kraken?

The Javelin is currently the only Capital ship that could accommodate the Ares based on its current dimensions. The Ares is too wide to fit in the Idris, Polaris and 890 but would be able to land on the larger Kraken pads.
