The D77H-TCI is a fleet-wide upgrade to the UNSC's Pelican dropships, used in active service for more than fifty years. First seen deployed in November, 2552,^[4] the D77H-TCI Pelican is the primary tactical support aircraft of the UNSC. Like its previous model, the D77H-TCI Pelican serves as a multi-role purpose aircraft. The dropship is fully capable of atmospheric and\or limited spaceflight and can land almost anywhere without difficulty making it the primary troop transport of the UNSC.


The D77H-TCI has several drastic design changes to both the interior, and exterior, although the exteriors changes are not as noticeable as the interior is. The first significant change is in the cockpit area of the D77H-TCI which instead of having the pilot and co-pilot sitting next to each other, the co-pilot is now seated behind and above the pilot, the control's and instrument panels have been rearranged and upgraded for the D77H. A small holo-tank is installed in the cockpit, allowing an Artificial intelligence to project its holographic form to the craft's pilots.
