Utility cargo dropship.
Darters are cargo dropships that form the backbone of the Spirit of Fire's logistical system. Darters are loaded with carefully packaged cargo pallets and passengers aboard the Spirit of Fire. They are then launched to firebases in the combat zone, dropping off vital supplies and returning with injured personnel and strategic resources. A steady stream of Darters is vital for the just-in-time warfighting strategy of UNSC expeditionary operations on hostile worlds.
