The Quiet Aircraft Association was founded in 2004 with the purpose of bringing together and collecting the history of the development of the first acoustic stealth aircraft--primarily the QT-2PC and the YO-3A. Both of these airplanes operated successful in the Vietnam War between 1968 and 1971.
Our organization invites anyone who is interested in or is in involved in the development of acoustic stealth aircraft to join us.

Notes on the Vietnam War era developments of the QT-2PC and YO-3A with comments on logos.
The Quiet Thruster (QT) series Aircraft consisted of two Experimental QT-2s (no logo with tail numbers N2471 (and 2.) They were converted to tactical military aircraft with non-standard tail # 1 and #2 for the Prize Crew Operational Evaluation (OpEval, QT-2PC Logo ), and later refurbished/upgraded for the Prize Crew II OpEval (Chem Meo Logo). Still later, both aircraft were returned to the Navy and renamed X-26Bs with non-standard tail number 5345 (no known logo). The Q-Star Aircraft was a Lockheed Missiles & spacew Co "house" test aircraft with Tail Number N5713S (no logo). The YO-3As (tail numbers 69-18000 to -18010) were Pre-Production Full-Scale-Development Observation Aircraft, hence the "Y".
