Yield

The Federation's gas extraction division ran the numbers on fuel costs versus nebula accessibility and arrived at the Yield-class: a harvester with the longest fuel range in its class by a wide margin. Competitors harvest the easy nebulae close to trade lanes. The Yield harvests everything else. The single default harvester and open fitting give pilots room to customize for whatever the deep-range run demands. The hull won't survive a fight, but the Federation prefers routes where fights don't happen.
