Grumman project list

Hoping to stir upr some discussions (and undigging of half-forgotten infos) I post the Grumman projects list found in the Francillon's book (Putnam-Naval Insitute) on Grumman Corporation. As it's very well explained in the opening remarks, it is complete till G-128 and after veeeeery sketchy (to say the best). Anyhow, till G-128 it is fairly complete (this means circa 1956-57). Enjoy.
Uh, there is an obviuos error: G-118 and G-119 have been switched. G-118 is really the XF12F.

As a gracious addition, this is the list of the G-98 projects (F11F) to give an idea of the Grumman nomenclature. Read the notes, there i a surprise (hydro-Tiger...)

I stir a dscussion myself (hopefully). Look at those two model numbers, G-107 and G-109. USAF interceptor and high-altitude WS, 1955-1956 timeframe... And the 109 includes the Eagles too.. Sound familiar? Other competitors in the phantom competition for the long-range interceptor?

G-109 has to be an alternative to the Douglas F6D Missileer, I'd think, from the description.
Grumman's G-118 (XF12F) is the Phantom II rival, no?

G-118, yes. G-108, probably, but a little bit early (1956?). And G-107? ??? Not to mention G-119.

Hi Skybolt.

Many thanks for the information.

And so, Grumman did not participate in competition with Douglas Model D-6?? (XA4D-1).

If there are in it to the book(Grumman Aircraft Since 1929) more detailed of information on projects Model G-86 and G-92 if it is possible tell to us(3-view drawings, figures and specifications )

Uh, no and no... I'll search in the individual plane histories but I doubt it. The VTO could be related to the same competition of the Pogo.

Hi Skybolt.

I in one read, that:
G-94----------XWF-1

and in book Grumman Aircraft Since 1929 it is written so:
G-94-----------Flex-deck F9F-7
G-95-----------XWF-1

If is in the book " Grumman Aircraft Since 1929 " about projects Model G-25, G-57, G-107 and G-124(figures,3-view drawings & specifications) show us if it is possible.

Nothing, again...
As for the G-94, etc, probably in my list there is a switch of numbers, as there surely is one between G-118 and G-119.

Looking for a drawing of the single J75-powered Design 118A for my F8U-3 monograph, I wrote the Grumman archives asking for information about the Design 119, listed in Francillon's book as the "XF12F design studies", whereas the 118 is listed as "Mach 2-plus fighter study", thinking that the 119 might have originally been the designation for the single-engine version. (Note that the 118 was not the XF12F as I've discussed elsewhere.) It turns out that Skybolt is almost certainly correct about Francillon switching the designations. Although it looks like a design suitable only for a Saturday morning kiddy cartoon, I can assure you that it is straight from the Grumman archives. I've included the notation on the drawing - the reversed writing is "Design 119" and "Three View". Note that this might be one of several sketches like the Design 110 series that I've described elsewhere.

I noticed that many people still don't realize the G-16 was Wildcat prototype in biplane configuration.
That's why the monoplane prototypes versions were designated G-18.

Does anyone know the G-numbers for the F-111B and X-29A? I don't think Grumman had to use GD's Model 12 number for its F-111B...

Grumman's G-310 is given as the TFX/F-111.
The projected RF-111B reconnaissance version was the G-431.
The X-29A was the G-712.

Right on...

...and the designations of the other versions of the F.111???
(RF.111A; RF.111D; F.111A to K; FB.111A and H; EF.111B)

These would be General Dynamics designations, not Grumman. Unfortunately these are not publicly known as far as I know. To me the F-111 is the GD-12, period. The GD designation system is pretty obscure to me, anyway, with two-digit numbers (GD-12, GD-14, Model 21, Model 44), three-digit numbers (Model 100, R-104, Models 201, 204, E-205, M-210, 218, Models 401 and 402) and four-digit numbers (Models 1600, 1601, 1602, 1700) — not to mention odd designations like VX-11... I hope someone will eventually shed some light on that question since GD is now defunct and a part of Lockheed.

Hi All!

G-344---Lunar Logistics System.
G-516---Naval Tactical Attack Aircraft.

Thanks nugo! Any dates?

Recently found a "Model 413 Lunar Landing Vehicle" and wondered if this could be the Grumman LEM...

SOURCE!

Is the concept really so difficult?

Hi Friends!

I like to explore and compare different sources and that I found, is "Grumman Aerospace Corp., Grumman Design 698, PDR No. 698-5, January 1978."---PDR No.698 aka Design(Model) 698, ""Future Naval Tactical Attack Aircraft (post) 1985" Grumman Aerospace Corporation, Report PDR-516-1, Vol.2, June 1971"---PDR-516---aka Design(Model) 516, Grumman Design 378B, Grumman Aircraft Engineering Corporation, ASR 378B, December 1965---ASR 378B aka Design(Model) 378B and etc.

And so, PDR and ASR---aka Design (Model), and so you can find in various sources project designation.

Source: http://books.google.com

and more:

Design 279---Apollo proposal.
Design 636---NASA/HiMAT proposal.

I tend to do pretty much the same as you. What is G-378B, anyway?

Hi,

G-159 & G-164 well known aircraft
G-191 Albatross for Germany
G-211 UF-2
G-231 Albatross for Canada

G-754 UAV
G-755 FAAV
G-870 VTOL fighter

The source for many projects is;

I have one conflicting number: the UF-2 version for Norway was G-244, not G-251.
G-251 was an ASW version of Canada's CSR-110 (G-231), which also entered service with USCG as SHU-16B.

Missing (or incomplete) from your list:

G-215 ASW version of UF-2 Albatross for Greece
G-226 version of SA-16B Albatross for Mercury capsule retrieval
G-231 CSR-110 Albatross SAR version for Canada, also used as ASW aircraft for USCG

G-730---VTX-TS , Grumman-Beech proposal.

Hi Nugo! Thanks for replacing the "no details" of my list with substantial descriptions!

I still have a G-137 that is undocumented. Any idea?

Also, isn't the spelling wrong on G-674? There was a Nutcracker, NOT a Nuttraker! A fuselage folding in flight is wacky enough, but I can't even begin to imagine a radome-carrying aircraft folding in two in flight! LOL

Hi All!

Nuttraker---mistake, yes correct---Nutcracker (G-674).

G-613---Lightweight fighter, single seat and single engined aircraft, canard-type, proposal.

Grumman Aircraft Data From 1930; Grumman Historical Office, June 1993 which I found at NNHC gives the F-111B as G-273.

I have the G-273 and the G-310 both as "TFX projects". I figure your source is reliable enough (!) and so G-273 it must be. Besides, the G-310 is posterior to the F-14 Tomcat (G-303) which indicates it was probably a spin-off of the F-111 but not the original program.

Actually, Grumman Aircraft Data From 1930 -- by the Grumman Historical Office, June 1993 which I found at the NHHC files has totally different lists.

FOREWORD

In 1967 Grant Daly published a compendium of Grumman aircraft statistics entitled Grumman Airplane Data (1930-1967). It contained a wealth of information and was a monumental task -- particularly working without the aid of a computer.

During the past 25 years various attempts have been made to bring the work up-to-date and to correct several errors in the original copy. That it is only now being republished will be some indication of the scope of the task.

The final rework and painstaking wrap-up of the document must be credited to Roger Seybel. Roger spent countless hours, mostly as a volunteer to the Grumman History Center, writing and verifying information with original sources. Without his persistence, you would probably not be reading this today.

Credit must be given to many - but, especially, former Grumman historians Andre Hubbard and Herman "Schoney" Schonenberg for their diligence in saving corrections to the original copy. William Barto and Peter Kirkup, assistant historians, also contributed significantly. Input was also provided by Joseph LeStrange, Joseph Lippert, Lynn McDonald, William Scarborough, Dave Seeman and Salvatore Vitale.

We know that someone will find an error in this copy. If so, please report same to the Grumman History Center at 516-575-2401. The material is now in a word processor; errors can be easily corrected in future editions.

Last.

The reason A-10 and JSTAR are on it is because grumman helped remanufacture some A-10s and was involved in the JSTAR program.

FB-111 or FB-111H maybe? ???

Awesome! But you posted file #10 twice and missed out file #11...

Whoops

I'm going through boxes of old AvWeek, and I found these pictures. Thought the designation nuts would like it

I have the complete article, if anyone is interested in learning more about it.

Nice! This one's new to me. Funny that this model number comes right before the one for the X-29...
