The Messerschmitt P.1103 Panzerjäger and P.1104 were a series of rocket-powered interceptors proposed by Messerschmitt.
The P.1103 and P.1104 were proposed in the early summer of 1944, with drawings for the proposals being finalized in August and September of that year. Both were light-weight interceptors of mostly wood construction and powered by a single rocket engine. The wings and vertical tail were adapted from the V-1 flying bomb. The fighter would be towed into the air behind a Messerschmitt Bf 109G or Messerschmitt Me 262.
The P.1103 and P.1104 were in competition with the Heinkel P.1077 and Bachem Ba 349, the latter being selected by the Luftwaffe over the others. Work on the P.1103 and P.1104 was abandoned in September 1944 to allow Messerchmitt to focus on the Me 262 and P.1101 projects.
