Capable of carrying many troops and supplies, Owls are considered to be stealth-capable. The crafts resemble a slightly smaller, lightly armored Pelican dropship, with the most notable difference being the Owl's cloud-gray finish and downward-curved wings. The Owl uses pivoting thrust nacelles to allow the craft to hover, and has a boarding ramp near its tail.
The Owl's passenger cabin is cramped, with seats for a total of ten passengers. Automatic crash harnesses ensure that passengers are safely secured within the Owl's seats. Aside from the ten inward-facing seats, the cabin contains a weapons locker at the forward bulkhead and enough space between the seats for some single-occupant vehicles. Owls have no artificial gravity. The Owl's canopy is constructed of aluminum oxynitride.
Owls were used during the conflict on the human Outer Colony of Gao. Admiral Tuwa's battle group attempted to reinforce the 717th Xeno-Materials Exploitation Battalion on the planet with Owls and Pelicans, but the crafts were attacked and either driven off or destroyed by the Gao Ministry of Protection's fleet of patrol corvettes. An Owl, the UNSC Silent Claw, was later used to extract Blue Team, Veta Lopis, and a Forerunner ancilla on the planet just before a HAVOK tactical nuclear weapon destroyed a local Forerunner installation. Another Owl, the UNSC Special Delivery was used by Blue Team during Operation: WOLFE.
