From publisher blurb: The Cavalo-class of cargo shuttles were designed by TriWorld Transport (a division of Trinity Exocorp) under military contract to carry industry standard cargo containers. Depending on the type of container slotted, a Cavalo can serve as a simple freight hauler, passenger carrier, prisoner transport, or weapons platform. Additional containers have been developed to serve as everything from office space, to medical facilities, to living quarters. There is no end to the variety of roles these shuttles could potentially fulfill. The lightly-armed Cavalo (Portuguese for “horse”) comes in three varieties: a small version that carries a single HMT-225 container, and two larger variants that haul either one or two of the big HMT-337 containers. The variants are designated the CV225, the CV337, and the CV337-D (for “doublewide”). This product presents the three varieties of shuttle, plus several container layouts in both sizes. The Cavalo’s have powerful VTOL engines and gravitics to support hovering and precise maneuvering. A built-in grapple and winch system can be used to retrieve, move, or deploy containers. Dedicated couplings are designed to secure the pod in place, supply external power, and allow easy access between the container and the shuttle cabin during flight.
