Which of the following refers to Navy logistics aircraft?

The C-2A Greyhound is considered a Navy logistics aircraft because it is specifically designed to transport personnel, supplies, and mail to and from aircraft carriers. Its role is crucial in maintaining the logistical support required for Naval operations, especially in carrier strike groups. The Greyhound can carry items such as spare parts and equipment from shore bases to ships at sea, ensuring that naval forces remain sustained and operational.

Other aircraft mentioned serve different roles: the P-3C Orion is primarily used for anti-submarine warfare and maritime surveillance; the T-45A Goshawk is a trainer aircraft designed for Naval student pilots; and the F-14 Tomcat is a multi-role fighter aircraft known for its air-to-air combat capabilities. Each of these aircraft has unique missions that do not revolve around logistics, further highlighting the specialized function of the C-2A Greyhound within the Navy's fleet.
