I like the idea, generally, but can build almost the same as the Raven one on an aerospace frame of 100 tons. Now, it was a very quick and dirty build, but I end up without the cargo space and 4.5 tons overweight. If I simply dropped the fuel mass down to 7.5 tons and armor to 23 tons, I've got a smaller piece of equipment (which might cost less), but is functionally similar.
What do it lose? It doesn't have the versatile 10 tons of cargo, it doesn't have extended length activities, slightly less combat range and slightly less overall armor (but still extremely beefy for a clan ASF at 442 points).
What do it gain? Quicker acting on the initiative order, carry-able in smaller bays, could be omni-ized to create a more versatile combatant. Potential cost/resource use reduction.
The Tundra Swan is stated to be a long range patrol craft, rather than effectively an over-weight strike fighter. That's really what both of these ought to be for, as ASF can't fill those roles on their own - though DS bases might actually be more effective as they have more mass to dedicate to listening arrays.
Critique over. I otherwise like both designs, they seem fairly functional and seem as though they could be something that both or either clan would consider.
