The Sparrow is a small class or airship that is primarily used by the Antifordian military as a scout ship. Its defining feature is a larger than standard envelope for its size. Since it is small, light, and has the increased balloon volume, it is capable of remaining aloft longer than most of the airships. Some have been converted to use helium as a lifting gas. These models have been able to reach much higher altitudes and remain aloft for longer, though they are significantly more expensive to operate due to the cost of helium.
They are popular among civilians, being the least expensive ships to purchase. It is commonly used for transportation, small scale shipping, and personal luxury crafts. It is also used by the Antifordian and Titanian postal services for transporting correspondence and packages.
