Beautiful detail on the all moving tail and B-2 style intakes. But darn, she needs restoring.

It looks a bit like the intake centerbodies were removed from the model?

What is the decal or artwork on the tail? It's awfully washed out to my eyes.

A crest of the city Bellefontaine Neighbors, an inner-ring suburb city in St. Louis County, Missouri, United States.
In this suburb the MDD NATF Monument is erected.

Great pictures Mark.  Any ideas of the dimensions of the model.  Its a shame its sitting out in the elements.  I'd like to see it inside somewhere and cleaned up, like my garage  B)

Hi folks,
now I find a few minutes to write a few lines to this topic.
I remember reading in the 90's, that the US Navy was very sceptical of canards during carrier approach and landing. That was one reason that Boeing, L-M, MDD and N-G cut off the canards on their JSF carrier variert design concepts .
So I wonder if this model still represents the NAFT design concept DP527 as shown and written in the book "Air Force Legends: Northrop YF-23 ATF by Paul Metz". Maybe N-G tried to please the US Navy and did some wind-tunnel tests with this model without the canards.
Another design concept designation like DP527 "letter" or DP5##.
On page 74 of that book you see a same model of the design concept DP527, but the label on model base writes DP531.
The design concept DP533, also shown on that page, has a conventional tail and no canards.
Maybe Tony Chong might give us some more information.

Anyway, great find and pictures, Airplane and Mark!!!  :) B)

This configuration is presented in Paul Metz's recent (and excellent) book about the whole YF-23 story.
This one is an iteration of the NATF without canards called the DP-533.

Thanks for the great pictures: the nose configuration and IRST integration is especially beautiful.
The pictures in Metz's book do not show it in such detail.

Strictly speaking, the model as displayed does not have any canards.  The DP-527 configuration did.  You will note the covered hole in the side of the forward fuselage approximately where the "post" for the canard should be.

It also appears that the inlet shock cones were painted black.  Between that and the deep shadows, it next to impossible to see them.

(Apologies to MarkN for mangling his excellent photo.)

Indeed, sorry for the confusion, I was wrong: this is obviously not DP-533 since it has no horizontal tail surfaces.
So it must be a DP-527 with canards removed, as you say.
The holes you mention are indeed located exactly where the DP-527 canards should be (significant dihedral).

Great eyes Craig - I readily stand corrected!

I am going to go up next week to City Hall and ask about our Museum restoring/painting it should I not be able convince them it deserves to be displayed inside at the Museum.  I'll understand if the answer is no, just got to ask though!

Enjoy the Day!  Mark

From the St. Louis Post-Dispatch, May 24, 2001.

I'm sure there's a story of someone who knew someone at Boeing, asked for something appropriate as a military memorial, and this is what they came up with.

Thanks George - saved me from hunting for it!

Indeed, I need to learn to ask the right question of the right person at the right time!

Yes, they're still there alright. Matt black paint hides the most surprising things, as witnessed with the Su-47 and its weapons bays or the shoddy build quality of the J-31.
