M620 Harpy Dropship 33 Troop Carrier

The M620 Harpy is a modern replacement to the Pelican. It is much larger and more weaponized than its predecessor. Although heavier, pilots say the Harpy flies like a dream, and its wingtip cannons are guaranteed to protect it from Covenant aircraft. Its large size allows it to carry more infantry than the Pelican ever did, which gave a big advantage to the UNSC.

History
The UNSC had plans to retire the DC series of Pelican. A company stepped up with their plans for a larger aircraft that could serve as a gunship. The DCX Dropship 33 was renamed to the M620, and was christened Harpy. The Harpy test aircraft was successful, and the M620 was mass produced. The M620 was delivered slowly to all squadrons, and the Pelican was slowly phased out, being replaced by the Harpy and other cargo dropships.
