What is the primary aircraft associated with the name "Orion"?

The primary aircraft associated with the name "Orion" is the P-3. The P-3 Orion is a four-engine turboprop anti-submarine and maritime surveillance aircraft that was developed by Lockheed Martin for the United States Navy. It first entered service in the 1960s and has been a critical part of naval aviation for anti-submarine warfare (ASW), maritime reconnaissance, and intelligence-gathering operations.

The name "Orion" specifically refers to this aircraft and its various upgraded versions, which have been used extensively in both peacetime and combat scenarios. The aircraft is equipped with advanced sensors and systems that allow it to perform long-range missions and effectively track submarines and surface vessels.

The other aircraft listed do not carry the name "Orion" and serve very different roles within the military aviation landscape. The F/A-18 is a multirole fighter jet, the T-2 is a trainer aircraft, and the OV-10 is a light attack and observation aircraft, none of which are related to the P-3 Orion or share its capabilities.
