Luftfahrt International N.24 1977 p.3797-3820 "Schnellstbombenträger": Factory drawings, project description, calculated specifications.The 'Daimler-Benz' projects, aside from the fact that they weren't designated 'A' to 'F' by the Germans, were actually designed by Focke-Wulf (see attached) as I've said elsewhere. However, it's never been disputed that the Focke-Wulf designs were based on a concept originated by Daimler-Benz - namely that a handful of very fast bombers could be used to devastate RAF and USAAF air bases without fear of being shot down. The difficulty of how to get such bombers airborne when all of Germany's long concrete runways had been destroyed was to be overcome using a large carrier aircraft which would get the bomber aloft (so it didn't have to use its own relatively small and weak landing gear) then return to pick up another bomber and do it all over again. The carrier could also be used to carry a small fleet of suicide aircraft if necessary. Daimler-Benz project A-F

Project A
This was the first of several designs for a massive carrier aircraft. The DB Project "A I", as the carrier aircraft was known, had a straight wing with taper and a slight dihedral on the outer wing sections. Four or six He S 021 turboprops were mounted on pylons that were mounted on the wing leading edge. The undercarraige was of a fixed arrangement, with a wide 24.97 m (82') track, and contained three wheels on each leg. The DB Project "A II" twin-jet bomber was slung under the "A I" carrier and was carried aloft to conserve the "A II" jet bomber's fuel. It was then released after nearing the target. The "A II" bomber had sharply swept back wings and tailplanes, with two BMW 018 turbojets mounted beneath the wings, much like the Me 262. A crew of three or four sat in a pressurized cockpit located in the extreme nose of the bomber. A V-tail was fitted to help the bomber mount under the carrier aircraft more easily, A bomb load of 30000 kg (66000 lbs) was envisioned.


A I Carrier Span: 94 m (308' 7.6") Length: Unknown Max. Speed: Unknown
A II Bomber Span: 26.16 m (85' 10.7") Length: Unknown Max. Speed: 1000 km/h (621 mph)


Project B
This was a revised design of the Daimler Benz Project "A" carrier aircraft and parasite jet bomber. The wing was straight with a taper on the outer wing leading edge, and featured pronounced anhedral on the inner wing sections and dihedral outboard of the landing gear. Six DB 603 piston engines provided the power, four pulling and two pushing. The high, fixed landing gear was located beneath the outboard engine nacelles, and had three wheels partially enclosed in the landing gear legs. The high, fixed landing gear and the anhedral gave the proper clearance to mount the parasite bomber beneath the carrier aircraft. The bomber featured sharply swept back wings and tailplanes, the latter also having pronounced dihedral and twin fins and rudders, much like the Henschel 132 (see three-view drawing below). Power was provided by a single, huge Daimler Benz DB S 06 jet engine (mounted on the top centerline of the fuselage), which was to supply 12930 kg (28446 lbs) of thrust. A crew of two sat in the pressurized cockpit that was located in the extreme nose of the bomber. 30000 kg (66000 lbs) of bombs was the projected bomb load.


Project "B" Carrier aircraft Span: 54 m (177' 2") Length: 35.8 m (117' 5.45") Max. Speed: Unknown
Project "B" Jet Bomber Span: 22 m (72' 2.14") Length: 30.75 m (100' 10.63") Max. Speed: Unknown

Project C
This design dates from early 1945, and was also to be a carrier aircraft (like the Daimler Benz Project "A"). The Daimler Benz Project "C" was basically the Daimler Benz Project "B" without the single jet engine bomber attached. The wing was straight with a taper on the outer wing leading edge, and featured pronounced anhedral on the inner wing sections and dihedral outboard of the high, fixed landing gear. Six DB 603 piston engines provided the power, four pulling and two pushing. There were two different parasite manned missiles that could be carried by this aircraft, the Daimler Benz Project "E" and the Daimler Benz Project "F".
Span: 54 m (177' 2") Length: 35.8 m (117' 5.45") Max. Speed: Unknown
Project E
The Daimler Benz Project "E" was designed as a piloted missile to be launched from the Daimler Benz Project "C" carrier aircraft. Five of these manned missiles could be carried at one time (see diagram below). The wings and tailplanes were swept back sharply, and power was supplied by a single He S 011 jet engine mounted on the bottom aft of the fuselage. 2500 kg (5500 lbs) of explosives were located in the nose of the aircraft, which were detonated on impact. Once carried aloft by the carrier aircraft, the DB Project "E" aircraft were then released near the target, with the pilot then choosing his target and then diving towards it. When the pilot was assured of a hit, he was to escape using the ejection seat. Although this aircraft wasn't officially considered a suicide plane, the pilot probably had a very small chance of survival, due to the speed of the aircraft in the attack and the proximity to the target when ejecting.
Span: 8.5 m (27' 10.6") Length: 9.2 m (30' 2.2") Max. Speed: Unknown

The Daimler Benz Project "F" was designed as a piloted missile to be launched from the Daimler Benz Project "C" carrier aircraft. Six of these manned missiles could be carried at one time (see diagram below). The wings and tailplanes were swept back sharply, and power was supplied by a single BMW 018 jet engine. 3000 kg (6600 lbs) of explosives were located in the nose of the aircraft, which were detonated on impact. Once carried aloft by the carrier aircraft, the DB Project "F" aircraft were then released near the target, with the pilot then choosing his target and then diving towards it. When the pilot was assured of a hit, he was to escape by a hatch located beneath the cockpit (see diagram below). Although this aircraft wasn't officially considered a suicide plane, the pilot probably had a very small chance of survival, due to the speed of the aircraft in the attack and the proximity to the target when escaping.


Span: 9 m (29' 6.33") Length: 12.96 m (42' 6.24") Max. Speed: 1050 km/h (652 mph)

Have read about these designs, but the logic of using carrier aircraft is refuteable, for the very reason you need them in the first place. They too would need a long runway, and since resources would be limited, wouldn't it have been better to expend those into building jet bombers that could use the very runways the carrier aircraft were to use? In a reference I have, the carrier aircraft was to operate from rough landing strips, but that's a stretch too far to imagine such a thing not using a lengthy runway to get off the ground; it's already long take-off run will be made longer by a rough strip, so what's to stop the Allies targetting them? Not surprisingly, the idea was not taken up by the RLM, or at least there's no record of what the RLM thought of the proposal and only preliminary concept drawings were prepared.
 
One wonders how the Germans expected to deal with fighters attacking these carrier aircraft.
