P-3 Orion and Sub SSN-774 poster art. This classic vintage style military aviation travel poster “P3-Orion and Sub SSN-774” is dedicated to all those who flew, maintained or supported the P3-Orion or Submarine class SSN-774. The Lockheed P-3 Orion is a four-engine turboprop anti-submarine and maritime surveillance aircraft developed for the United States Navy and introduced in the 1960s. Lockheed based it on the L-188 Electra commercial airliner. The aircraft is easily distinguished from the Electra by its distinctive tail stinger or “MAD Boom”, used for the magnetic detection of submarines. The Virginia class, also known as the SSN-774 class, is a class of nuclear-powered fast attack submarines (hull classification symbol SSN) in service with the United States Navy.
