In mid-December 1943 at the Arado facilities work began on a flying wing project. Straight wings retained their good aerodynamic characteristics only at subsonic speeds. Near-supersonic speeds a new approach to wing geometry. A discussion took place with the RLM in early 1944, and Arado was asked to compile design studies for a high speed long range jet powered bomber. It was realized that the project could best be fulfilled by using a flying wing design with a laminar high speed profile. Five variants of the wing were built, each differing in its sweep. The most advanced work on this project was carried out at Dedelsdorf airbase, where the Ar 234 V16 was being rebuilt as part of this research. The aircraft was destroyed in mid-April 1945 by advancing British troops as they captured the airfield.

In addition to the improvised night fighter adaptations of the Ar 234B-2, there were plans to produce a dedicated night fighter based on the four-engined Ar 234C-3. Two prototypes, the V23 and V27 were to be converted to represent Ar 234C-3/Ns fitted with a radar operator station. However, neither of the two prototypes was completed.
In early 1945 it was decided to start development work on a heavy night fighter version based on the Ar 234C airframe, designated the Ar 234P. This version was to feature an armoured cockpit of a new type, with both crewmembers sitting side by side. In the P-1 variant the engines were to be moved 40cm further aft in order to balance the weight of the new cockpit. However, the Ar 234P was another project that never left the designers' drawing boards.
Another variant was the 'D' version, to be powered by two Heinkel-Hirth HeS 011 engines. As the engines were never developed into series production units, this grounded the entire project.
On 25th October 1944, Arado made several proposals regarding the towing or carrying of the Fieseler Fi 103 flying bomb by the Ar 234C. The Heinkel He 111/Fi 103 combination was just entering service. It was anticipated that the inferior performance of the He 111 would result in severe losses being suffered, and consequently proposals were put forward to use the superior capabilities of the Ar 234.

Several other projects involving the Ar 234 as a towing machine were put forward. One involved the towing of a special auxiliary fuel tank via a non-flexible boom similar to that used in the first two Ar 234/Fi 103 projects. The Ar 234B-1 was to tow a fuel tank that was fitted with a simple two-wheelded take-off dolly and employed short stubby wings of square planform. The project was known as the "Deichselschlepp", but although tests proved very succesful, there is no record of the scheme being used operationally. Yet another "Deichselschlepp" project proposal involved the towing of a Henschel Hs 294 missile behind the Ar 234C.

Another proposal envisioned the Arado Ar 234 carrying a miniature fighter into the range of Allied bomber formations. The E.381 began in a proposal from Arado Flugzeugwerke to the Air Ministry for a parasite fighter, carried underneath another aircraft, to destroy Allied bombers. Three variants of the E.381, named Mark I, II and III, were designed. Each version was essentially an armored tube provided with armament and a Walter HWK 109-509 rocket engine for power. The aircraft would have carried enough fuel for two approaches to the target as well as a number of 30 mm rounds. After using all his fuel during an attack it was intended that the pilot would glide the fighter to the ground, deploy its drogue parachute, and land the aircraft on a primitive skid landing gear. None of the designs were ever completed due to its cancellation, though some wooden airframes and a single mockup were constructed in 1944 to provide prone-position training for pilots. The E.381 was cancelled due to a lack of funds and interest by the Ministry of Aviation, along with a scarcity of the mother Ar 234C aircraft.
