The '''Martin P4M Mercator''' was a maritime reconnaissance aircraft built by the [[Glenn L. Martin Company]]. The Mercator was an unsuccessful contender for a [[United States Navy]] requirement for a long-range maritime patrol bomber, with the [[Lockheed P-2 Neptune|Lockheed P2V Neptune]] chosen instead. It saw a limited life as a long-range electronic [[reconnaissance]] aircraft. Its most unusual feature was that it was powered by a combination of [[piston engine]]s and [[turbojet]]s, the latter being in the rear of the engine nacelles.
