While the lizards are smart with tech, they aren't the leaders of the alliance. Which means both would have to work together on a ship design. Because the lizards can put it together, but only at the command of the Grut. The Grut giving specifications like size, purpose, weaponry, defensive systems, and probably shape.

The Grüt are over confident in the fact that nobody could reach their ships. They don't even view this as a war, more of just as an extermination of pests
