This prototype fighter and bomber was the first flying wing plane to be powered by jet engines. Its design was a response to a call from Luftwaffe commander Hermann Göring for a light bomber that would be capable of carrying 1,000kg across a distance of 1,000 kilometres at a speed of 1,000km per hour. Messerschmitt Me 264 – an Amerikabomber candidate with four inline or radial engines and a range of 15,000km, three airworthy prototypes built and flown.

Tas – a local attempt to replicate the heavy Panther or the "Tiger 2" tank (2 incomplete prototypes produced, including 1 complete hull). [8] Type XI – a U-boat designed to carry the Arado Ar 231 collapsible floatplane and have 128mm turrets; four were laid down but canceled at the outbreak of World War II.

G5N Shinzan – a prototype bomber developed as a part of Project Z, the Japanese counterpart of Amerikabomber project.

A6 – planned version of the A5 with different propellants; may have also been a proposal for a manned reconnaissance version of the A4b/A9.

Cook's publication introduced the topic in English without critically discussing the subject. [5] More recently, historian Eric Kurlander has discussed the topic in his 2017 book on Nazi esotericism Hitler's Monsters: A Supernatural History of the Third Reich. According to reviewer Julian Strube, Kurlander "cites from the reservoir of post-war conspiracy theories" and "heavily relies on sensationalist accounts...mixing up contemporary sources with post-war sensationalist literature, half-truths, and fictitious accounts". [6] Henschel Hs 293 – a pioneering MCLOS-guided, launch-boosted air-to-ship missile using the Kehl-Straßurg radio link as with the Fritz X, used in combat from 1943 to 1944. Landkreuzer P. 1000 " Ratte" (Rat) –A planned super-heavy tank, weighing 1000 tonnes and armed with two 280mm cannons, one 128mm anti-tank gun, 8 20mm flak guns and 2 15mm heavy machine guns; cancelled in early 1943. Type XVIII U-boat – a U-boat designed to use air-independent propulsion; several were under construction when the war ended. Landkreuzer P. 1500 " Monster" – a proposed super-heavy self-propelled gun, weighing 1500 metric tons and armed with the 800mm Schwerer Gustav/Dora gun.

Fallschirmjägergewehr 42 – an automatic battle rifle developed specifically for the Fallschirmjäger. I (1942) – a planned 56,500 ton aircraft carrier, converted from a transport; cancelled before work started. Heinkel He 162 Spatz – Winner of the Volksjäger (People's Fighter) design competition for a single engined turbojet fighter.

Heinkel He 277 – a planned, advanced long-range bomber design, designated by RLM by February 1943, inheriting many He 219 prototype design features during its evolution but never built as a complete aircraft, evolved to be an Amerikabomber candidate, to be powered with four BMW 801 radial engines and up to 11,000km range. Self-propelled 75 mm Reșița Model 1943 – 2 prototypes completed and tested (reportedly, this vehicle served as the inspiration for the Hetzer, or as a significant influence in the latter's development).

Fliegerfaust "Pilot Fist" or "Plane Fist" / Luftfaust "Air Fist" – the first man-portable air-defense system (MANPADS) anti-aircraft weapons system. H-class battleship – a series of proposals for battleships surpassing both the United States Navy's Montana-class battleships and the Imperial Japanese Navy's Yamato-class battleships in armament, culminating in the H-44, a 140,000 ton battleship with eight 20 inch guns. Two H39-class hulls only laid down; scrapped on slipways. Messerschmitt Me 323 " Gigant" (Giant) – a heavy transport with six engines, adapted from the Me 321 giant troop-glider.
