The Mammoth-class Heavy Hauler is a ubiquitous sight throughout the galaxy. The long, cylindrical ships can haul ten times as much cargo mass as the commonly used BFF-1 freighter and can reliably haul massive amounts of raw materials from one end of the galaxy to the other. It is truthfully said that entire worlds have been developed from the cargo holds of just a pair of these gigantic ships.

That the Mammoth heavy hauler is so successful is more a tribute to sheer stubbornness and a brilliant initial marketing campaign from the first manufacturer of these ships than to excellence of design. The freighter has easily the worst cargo-to-weight ratio of any heavy freighter. While a ratio of seventy percent or more is common in order to maximize cargo-carrying efficiency, the Mammoth's is an underwhelming twelve and a half percent. This is because the makers, knowing the ship would not be subject to planetary gravity during landings, using the cheapest and therefore heaviest materials in the ship's construction. This resulted in hull thicknesses equal to Imperial Star Destroyers, but a fraction of the hull strength. Designers had to add internal bulkheads to maintain hull integrity, further limiting the available cargo space.

The Mammoth class also mounts engines that barely meet the minimum requirements to get the ship moving, both in hyperspace and in-system. This, coupled with the fact that the ship has absolutely no defensive armament, means that the ship is easy prey for any half-serious bandit or pirate, especially with the very small crew complements normally embarked. Despite these drawbacks, Mammoths continue to see service throughout the galaxy, with a small number being built every year.
