Even before the Messerschmitt Me 262 had formally entered service with the German Luftwaffe in 1944 as the world's first jet-powered fighter, company engineers were already looking for ways to improve on what would quickly become an obsolete design in the scope of World War 2 (1939-1945). Beginning around mid-1943 a new form based on the fighter was drawn up as a two-man fighter using a deeper fuselage while retaining the wings and tail unit of the original Me 262 product. The underslung twin-engine arrangement (2 x Junkers Jumo 004C) was retained and the initiative came to be known as the "P.1099".
Proposed primary armament was a mix of cannon: 2 x 20mm FPL 151 cannons in a rear-facing, remote-controlled dorsal barbette with 2 x 20mm FHL 151 cannons in single-gunned, rear-facing, side fuselage, remotely-controlled barbettes. 2 x 30mm MK 103 cannons were fitted to the nose in fixed, forward-firing mounts operated by the pilot.
Work continued into early 1944 at which point more roles were added to what was now becoming a multirole performer - the single airframe was to be marketed as an interceptor, high-speed bomber / reconnaissance, bomber-destroyer, night fighter and trainer for the Luftwaffe. This also meant that engineers now toyed with various armament fits that included 20mm cannons, 30mm cannons, 50mm cannons, 55mm cannons and upward-firing (Schrage Musik) cannons. The latter was to make up part of a night-fighting model which was set to carry radar as well.
The end of the war in Europe in May of 1945 ended all hopes for the P.1099. By this time, the project had evolved another related twin-engined model in the "P.1100" - this version incorporating swept-back wing mainplanes for higher-speed flight as an all-weather day fighter. This project, itself, spawned another fighter form in the single-seat "P.1101"
which had been drawn up to fulfill the requirements of the Emergency Fighter Program of 1944. None saw the light of day and their details either destroyed or captured by the conquering Allies.
