Leverage

The Leverage-class carries 140 units of cargo with a pulse laser pointed at anyone who objects. The Federation designed it for routes where hiring an escort costs more than the margin on the cargo — which, at current insurance rates, is most of them. The reinforced hull absorbs hits that would crack a standard courier, and the 25% fuel efficiency bonus stretches a tank across 70 jumps. At Speed 2 the Leverage is not fast, but a slow delivery beats a lost shipment every quarter. Independent traders call it the ship that doesn't need a babysitter.
