So lately I became very suspicious about an aircraft named Dassault Mirage III NG I had never heard of it and decided to do some digging through the internet to find out everything you can find out about it. I wasn't surprised when I couldn't find out much, But, "What is this image, Neru21?" Here is the Image:

Dassault Mirage III NG:

Note the wing shape and canards

This seems to be the only blueprint that exists:

I have also discovered some charts and manuals for the Mirage III
Here

As I have been searching for an answer to this aircraft, I also came across this image:

This aircraft is known as the Dassault Mirage IIIRS R-2109

I then decided to look more closely at canard aircraft and saw this:

On the Mirage variants page, I can find a description of of the Mirage IIIEBR-2:Refurbished and updated aircraft for the Brazilian Air Force, with canard foreplanes. Four ex-French aircraft sold to Brazil in 1988, with surviving Mirage IIIEBRs upgraded to same standard.

The next paragraph of information discovered by RepublicOfCursedPlanes
Following the development of the Mirage 50, Dassault had experimented with yet another derivative of the original Mirage series, named the Mirage IIING (Nouvelle Génération, new generation). Like the Milan and Mirage 50, the IIING was powered by the Atar 9K-50 engine. The prototype, a conversion of a Mirage IIIR, flew on 21 December 1982.[112]
The Mirage IIING had a modified delta wing with leading-edge root extensions, plus a pair of fixed canards fitted above and behind the air intakes. The aircraft's avionics were completely modernized, making use of the parallel development effort underway for the next-generation Mirage 2000 fighter. Chiefly amongst these changes, the Mirage IIING used a fly-by-wire system to allow control over the aircraft's relaxed stability. The aircraft had an improved nav/attack system with inertial navigation and a head-up display. A variety of radars could be fitted, including the Cyrano IV and Agave and these could be supplemented by a laser rangefinder. The uprated engine and aerodynamics improved take-off and sustained turn performance.[113][114]
Ultimately, the type never went into production, but to an extent the Mirage IIING was a demonstrator for various technologies that could be and were featured in upgrades to existing Mirage IIIs and Mirage 5s. After 1989, enhancements derived from the Mirage IIING were incorporated into Brazilian Mirage IIIEs, as well as into four ex-Armée de l'Air Mirage IIIEs that were transferred to Brazil in 1988. In 1989, Dassault offered a similar upgrade refit of ex-AdA Mirage IIIEs under the designation Mirage IIIEX, featuring canards, a fixed in-flight refueling probe, a longer nose, new avionics, and other refinements.

This shows that the aircraft must've existed in one point in time.

"But Neru21, what does this mean for SP?

I've been wanting to make a VR replica for quite some time now, so I thought that
this would be a very good project. Seeing that (from my research) there is a small number of VR Mirages (or similar aircraft), this aircraft would stand out in the community if I put some time into it.

When will this happen?

I've made a schedule/roadmap over the past 3 days about what needs to happen and when:

I'll see you all later!
