Here it was; Willy Messerschmitt-Pionier der Luftfahrt und des Leichtbaues,

it's a first known Project as I expected

So no primary source then.

because the first Messerschmitt
Project after WWII was P.1118

What is your source for that?

OK my dear Dan,

but what was about P.1113 & P.1114 ?.

Hi,

for saying the P.1116 was not existed,I suspect in that,because the first Messerschmitt
Project after WWII was P.1118,that meant there was a series until P.1117 at least.

And you have concrete evidence that Messerschmitt's first postwar design was the P 1118? From a primary source document? Post it up.
I know you are a great advocate of the P 1116 but all contemporary German sources (e.g. interviews with Voigt and Hornung) agree that the P 1112 was the last wartime Messerschmitt type. Their war was over and they wanted jobs with the Americans - what possible (non-ridiculous conspiracy theory) reason could they have for lying about the existence of four super super secret projects, especially when they knew the Americans had captured all their project papers?
Have a look at the attached page. It is the only shred of contemporary evidence (A.I.2(G) Report No. 2383 German Aircraft: New and Projected Types) that supports the existence of a P 1116. Read what it says:
"This project is similar in outline to the P 1101 except that the pilot sits at the tail end of the fuselage behind the fuel tank. Performance was not improved and design resulted in bad visibility for the pilot."
It's describing the P 1106. There is no P 1116 - it's just one mistake in one source, 72 years ago. Maybe it's time to correct it and move on.

Albania

Unnamed
Submarine, class not specified
No other details provided.

Russia

Allende (Named after Salvador Allende (President of Chile, 1970 - 1973).)
Guevara Class Guided Missile Destroyer (Fictional)
Nuclear Powered
Speed: 50 knots
Described as having "...a low, clean profile and flared bow, she hugged the water to make radar detection difficult."
Gun Armament: "...some forty-millimeter guns mounted on the bridge." (Russians do not use 40mm guns.)
Missile Armament: SAMs and SSMs (Launchers are concealed below decks and only raised above deck to fire.)
Note: Specifically identified as the third member of the class (Lead ship is presumably named either Guevara or Che Guevara, this is not however specified in the text.). The small gun armament is the result of a need to keep the ships weight down.

Juan Bosch (Named after Juan Emilio Bosch Gaviño (President of the Dominican Republic, 1963).)
Guevara Class Guided Missile Destroyer (Fictional)
Details same as Allende

Note: The members of the Guevara Class are all named after Latin American revolutionary leaders. Like the real world Mod-Kashins, their function  is to serve as 'tattletails' following the US carrier groups at the edge of radar range. In the event of hostilities, they will call down a strike on the carrier group and then fire every SSM they are armed with at the carrier before retreating at high speed.

Semenoff
Ballistic Missile Submarine of unspecified class.
No other details provided

United States

USS Nimitz (CVN-68)
Nimitz Class Aircraft Carrier
Real ship, details as in service.
Air group in this novel includes Spectre fighter-bombers.

For the aircraft mavens, some fictional US aircraft.

Shrike
VTOL Fighter Aircraft
Mach 3 Capable
No other details.

Spectre
Fighter-bomber
Nuclear capable
No other details.

Plot summary: It is the day after tomorrow (and somewhat off to one side...), following the Yom Kippour War, the superpowers have faced each other across the line of 34 East running down the Sinai peninsula. As the US and Russian governments move to renew the treaty, Chinese backed terrorists strike, creating a situation that leads to the brink of World War III. 

Note: The author does not provide any specific dating information beyond the presence of the USS Nimitz (CVN-68) which means the events depicted cannot take place before May of 1975 when the Nimitz commissioned. While the novel only covers a few days, the events in question are most likely taking place somewhere between 1975 - 1990.

The author wrote that he started work on this novel in 1967 shortly after the Six-Day War, and when the Yom Kippour War occurred used it to replace a fictional conflict he had created for the purpose of the novel. This write-up was based on the Readers Digest edition of the novel. Should I locate a copy of the actual novel I will revisit this post.

L’abandon en 1960 du réacteur M26/M284
 Super Atar développé entre
1955 et 1958 pour propulser à Mach 3 le
« Super Griffon » (programme arrêté) prive le
motoriste d’un réacteur militaire puissant

Quote
A l’autre bout de la chaîne des produits, la
SNECMA, à la demande du ministère de l’Air
en 1961, lance l’étude d’un réacteur léger
capable de fonctionner horizontalement et
verticalement, l’expérience du « Coléoptère »
ayant démontré la faisabilité de cette solution.
Le M36 présenté en 1962 est compact et ultraléger
(180 kg) et délivre 2 000 kg de poussée.

Quote
En 1962, d’autres études démarrant pour
Dassault (programme ADAV), la SNECMA
engage les programmes M36 SF à tuyère
directionnelle

le M41 A à simple flux, le M41
S
à double flux et le M41-Z0M2 (altitude zéro
mètre vitesse Mach 2) délivrant 3 000 kg de
poussée.

Aucun de ces projets n’aboutit, les
Services techniques de l’aéronautique ayant
fait le choix d’une autre solution, que l’on
retrouvera sur le Dassault « Balzac »

Quote
dont le JT-11 B3, la version civile du J-58 (le
plus puissant réacteur militaire du moment) a
le potentiel requis. Le projet de réacteur civil
franco-américain SNECMA-Pratt & Whitney
prend le nom M35

Quote
avec Bristol-Siddeley (12 réacteurs
prototypes M-45 vendus)

Les développements basés
sur un corps hautes pressions de l’ATAR ont
échoué.

 L’étude du réacteur de dix tonnes
désigné M56 piétine.

Quote
En 1965, la SNECMA commence l’étude
d’un petit réacteur double flux d’une tonne de
poussée destiné aux avions d’affaire et de
liaison dont le Dassault « Mystère » 20 (deux
réacteurs GE CF-700) constitue l’archétype.
Le moteur est désigné M49.

SOME INSIGHT INTO DOUGLAS'S EARLIEST MODEL NUMBERS

The earliest Douglas Model number properly identified is "109" (as in DC-1-109). What about the first 108? Did they exist? Were they used at all?

A finding aid recently published on the web has enabled me to lift at least a corner of the veil.
It is entitled The Donald Douglas Collection of Corporate Documents, Engineering Drawings and Library Materials 20-01-07 and was prepared by K. Williams.
Published by the Museum of Flight Archives in Seattle, it is unfortunately full of typos but after some adequate processing and cross-referencing it I have been able to extract some useful data from it.

The second and most interesting part of the 141-page document is entitled "Douglas and Davis-Douglas Company Engineering and Model Drawings" and lists all the company drawings that are part of the museum's collection.

Those two documents are now "dead". Mind uploading them?
