The Mirage III family grew out of French government studies begun in 1952 that led in early 1953 to a specification for a lightweight, all-weather interceptor capable of climbing to 18,000 m (59,040 ft) in six minutes and able to reach Mach 1.3 in level flight.
Dassault's response to the specification was the Mystère-Delta 550, a diminutive and sleek jet that was to be powered by twin Armstrong Siddeley MD30R Viper afterburning turbojets, each with thrust of 9.61 kN (2,160 lbf). A SEPR liquid-fuel rocket motor was to provide additional burst thrust of 14.7 kN (3,300 lbf). The aircraft had a tailless delta configuration, with a 5% chord (ratio of airfoil thickness to length) and 60 degree sweep.

The tailless delta configuration has a number of limitations. The lack of a horizontal stabilizer meant flaps cannot be used, resulting in a long takeoff run and a high landing speed. The delta wing itself limits maneuverability; and suffers from buffeting at low altitude, due to the large wing area and resulting low wing loading. However, the delta is a simple and pleasing design, easily built and robust, capable of high speed in a straight line, and with plenty of space in the wing for fuel storage.
The first prototype of the Mystere-Delta, without afterburning engine or rocket motor and with an unusually large vertical stabiliser, flew on 25 June 1955. After some redesign, reduction of the fin to more rational size, installation of afterburners and rocket motor, and renaming to Mirage I, in late 1955, the prototype attained Mach 1.3 in level flight without rocket assist, and Mach 1.6 with the rocket.
However, the small size of the Mirage I restricted its armament to a single air-to-air missile, and even before this time it had been prudently decided the aircraft was simply too tiny to carry a useful warload. After trials, the Mirage I prototype was eventually scrapped.
Dassault then considered a somewhat bigger version, the Mirage II, with a pair of Turbomeca Gabizo turbojets, but no aircraft of this configuration was ever built. The Mirage II was bypassed for a much more ambitious design that was 30% heavier than the Mirage I and was powered by the new SNECMA Atar afterburning turbojet with thrust of 43.2 kN (9,700 lbf). The Atar was an axial flow turbojet, derived from the German World War II BMW 003 design.

The new fighter design was named the Mirage III. It incorporated the new area ruling concept, where changes to the cross section of an aircraft were made as gradual as possible, resulting in the famous "wasp waist" configuration of many supersonic fighters. Like the Mirage I, the Mirage III had provision for a SEPR rocket engine.The prototype Mirage III flew on 17 November 1956, and attained a speed of Mach 1.52 on its seventh flight. The prototype was then fitted with the SEPR rocket engine and with manually-operated intake half-cone shock diffusers, known as souris ("mice"), which were moved forward as speed increased to reduce inlet turbulence. The Mirage III attained a speed of Mach 1.8 in September 1957.
The success of the Mirage III prototype resulted in an order for 10 pre-production Mirage IIIAs. These were almost two meters longer than the Mirage III prototype, had a wing with 17.3% more area, a chord reduced to 4.5%, and an Atar 09B turbojet with afterburning thrust of 58.9 kN (13,230 lbf). The SEPR rocket engine was retained, and the aircraft were fitted with Thomson-CSF Cyrano Ibis air intercept radar, operational avionics, and a drag chute to shorten landing roll.

The first Mirage IIIA flew in May 1958, and eventually was clocked at Mach 2.2, making it the first European aircraft to exceed Mach 2 in level flight. The tenth IIIA was rolled out in December 1959. One was fitted with a Rolls-Royce Avon 67 engine with thrust of 71.1 kN (16,000 lbf) as a test model for Australian evaluation, with the name "Mirage IIIO". This variant flew in February 1961, but the Avon powerplant was not adopted.
Mirage IIIC and Mirage IIIB
The first major production model of the Mirage series, the Mirage IIIC, first flew in October 1960. The IIIC was largely similar to the IIIA, though a little under a half meter longer and brought up to full operational fit. The IIIC was a single-seat interceptor, with an Atar 09B turbojet engine, featuring an "eyelet" style variable exhaust.
The Mirage IIIC was armed with twin 30 mm DEFA revolver-type cannon, fitted in the belly with the gun ports under the air intake. Early Mirage IIIC production had three stores pylons, one under the fuselage and one under each wing, but another outboard pylon was quickly added to each wing, for a total of five. The outboard pylon was intended to carry a Sidewinder air-to-air missile (AAM), later replaced by Matra Magic.

Although provision for the rocket engine was retained, by this time the day of the high-altitude bomber seemed to be over, and the SEPR rocket engine was rarely or never fitted in practice. In the first place, it required removal of the aircraft's cannon, and in the second, apparently it had a reputation for setting the aircraft on fire.[citation needed] The space for the rocket engine was used for additional fuel, and the rocket nozzle was replaced by a ventral fin at first, and an airfield arresting assembly later.
A total of 95 Mirage IIICs were obtained by the AdA, with initial operational deliveries in July 1961. The Mirage IIIC remained in service with the AdA until 1988.
The French Armée de l'Air (AdA) also ordered a two-seat Mirage IIIB operational trainer, which first flew in October 1959. The fuselage was stretched about a meter (3 ft 3.5 in) and both cannons were removed to accommodate the second seat. The IIIB had no radar, and provision for the SEPR rocket was deleted, although it could carry external stores. The AdA ordered 63 Mirage IIIBs (including the prototype), including five Mirage IIIB-1 trials aircraft, ten Mirage IIIB-2(RV) inflight refueling trainers with dummy nose probes, used for training Mirage IVA bomber pilots, and 20 Mirage IIIBEs, with the engine and some other features of the multi-role Mirage IIIE. One Mirage IIIB was fitted with a fly-by-wire flight control system in the mid-1970s and redesignated Mirage IIIB-SV (Stabilité Variable); this aircraft was used as a testbed for the system in the later Mirage 2000.

My new project ...
About the kit ... One big piece of scum, the worst. :-evil :(
Model no complete cockpit.Without instrument panel, seat of the poor, must be installed pilot, never not seen a model without the instrument panel.
One huge complaint is that the right border troops distorted.It must be corrected with a lot of putty when they fit the wings.
Fit is more or less bad, and the rest of the casting is to five models.
The reason for my purchase of these models is because I was excursion (Abitur) in Italy, and they like the models have never hear.accidentally I ran into this kit, so I quickly buy.I hadn't time to see what inside.No, this will still be done, not bad for learning.By the way, models for skill 1 :-cool
-
Work started... :-jump
-
Yep, the good old Airfix - acceptable for practice only :-/
Next time try not to put so much putty, you'll have troubles scrapping it off... :-think
-
This kit look simple and nice, very relaxing to built!
-
Done for today.There are things to be fix...
:-salut
-
Take a note about the paints in package, they could be water soluble paints, they dry much faster. Here you are some archive images :-flo
-
Yes, these are acrylic paint, which is diluted with water, when diluted to dry much faster, and easier to apply a thin layer of diluted paint, but not diluted. :-salut
Thank for advice and pics! :-flo
-
It is nice kit to practice on...
I am sure you will do a great work

:-flo

Hi mate, :-salut :-salut
The Mirage III C : what a beautiful plane ! I know it very good...
I'm waiting for the end of this build.
This kit is a very good base. I made one some years ago and is to be seen here :

Incredible build my friend :-clap :-clap
-
Thank you very much. :-obey
I have to say it took me several weeks of work to achieve such a rendering...
Cheers,
Jicehem :-wave :-wave
-
Wow :-eek :-eek :-eek
What work ! :-obey :-obey :-obey :-obey
I'm impressed! :-love :-love :-salut
:-wave
-
Well, finally found some time to dedicate myself to this plane. I don't have much time, and have lot to learn in school, however, i decided to separate hour to run this wonder ... :-flo :-tri
:-wave
-
Dark shades over the joint lines- filler?
-
Yes,it is filler.I don't know why,but it's darker than usuall.I think that plastic is not like before,so it looks darker!
-
Hi Sall,
I suppose you'll finish your Mirage as it's given by the decal sheet.
In this case, you can't use the Matra missile because too an old missile for the period 1978 to 1988 in Djibouti. Mirage III Cs of EC 3/10 "Vexin" were armed with Matra Magic I and they were the only ones Mirage III Cs having the possibility to be so armed.
Cheers,
Jicéhem
-
Very useful advice.Thank you. :-flo
Do you know,where i can find a suitable missile?In Serbia,it is hard to find something that!
I think,i would with appropriate info and images missiles,that could make the wood.When i was young,i played with wood.
Can you give me some image and info about the missile,or links,so i tried to make from wood.It' interesting!
-
Hi Sall, :-salut :-salut
See here :

Hello Jicehem.
I need your help and your advice.
My model (Airfix), there are only 3 points subconsciously. One is in the middle for R530 missile, the other two are for I do not even know what it is. (Probably the extra fuel tanks)
Plane of the box (with the dekals and the camouflage, who served in Djibouti) would need to have 5 points subconsciously (if I understood well)-one in the middle and two for what I do not know what is (probably the extra fuel tanks ) and two for the Matra R550 missile.
If the rocket R530 fallen into disuse, what should I put in her place?
That you could hang some pictures(I need pictures with full weapons) (the more the better),so I'd better see what needs to fix.
This is pics of my kit:
-
This google translate you're using shall not take you to the second page of the street... :-/
-
Good images...
http://www.primeportal.net/hangar/gunther_neumahr/mirage_iii_s/
And on your image- two slot on wings is for fuel tanks
-
Thank you mate for images,and everything else! :-flo
Is the underside of the aircraft HU65, as indicated in the instruction, or it's not true? :-think
Will this be enough paint to paint models?
-
Far enough... about the bottom color is possible.
-
Ok! :-ok
Thank for info mate! :-flo
-
This material gave me the Samuraj.
This material say that bottom of the plane is Hu47,and i will painted the bottom in the Hu47. Definitely

Here we are ... :-jump
Srecko sent me the Magic and Sidewinder missiles, as well as their rails, and two types of fuel tank. One major and one minor. :-flo :-obey
On the wing I'll put Magic missiles, as well as larger fuel tanks and the hull will put a smaller fuel tank (instead of R530 missile). ;)
:-wave
Ps.Thank you Srecko! :-flo :-obey
-
Enjoy :))
-
I'm impatient to see what will follow...
-
My first re-scribering panels! :-roll
I worked only on the top side of the wings. :-ok
-
For first time this can go :-ok But- must use soft movement when making path for the panel, light pressure and then a little bit harder. But all of this is promising
-
Yes Sir :-salut
Thanks for the advice, it is certainly welcome. :-ok :-flo
:-wave
-
Well done, Sall. To fill the excess of rescribing, simply use cyano glue...
-
Thanks! :-flo
Good advice. I didn't know that! :-flo :-flo
-
I finished with the fuel tanks ... ;)
That's all for this weekend! :-joke
-
Panels re-scribed on the left side of the aircraft .... :-jump
I think I'm better now than last time, but I have still a lot to practice. :)) :-razz :-tri
:-wave :-salut
-
Great job!
-
What do you use for rescribing?Just remember a lot of patiance and a steady hand.Also try to press less next time.
-
I use scriber (http://www.letletlet-warplanes.com/forum/off-road/my-first-scriber!/)
I will try next time to press the less! :-salut
-
The right side of the vertical tail :-jump
-
As you see- better then on the very start :-clap
-
I agree.And I think it's better than at the beginning. :-jump
-
Much better Sall, next time try to apply less pressure on scriber and the panel lines won't be so deep.
Very well, go on mate
-
Now the lines are less deep than the last time.I think there should be less deep than it is now.It be better next time!
-
Yes, just go on, man! :-ok :-clap :-clap :-clap :-wave
-
Re-scribering over. :-joke
-
Yes!! Thats the spirit!!
-
Lookign great.If you think those are too deep,than use a little super glue or CA cement and run into each line.This should be done very cerafully becouse you can easly make mistakes.
-
Thank you :-flo
I will try it on a peace of plastic,so if it works,i try on Mirage.
-
impressive most impressive,my friend! :-green :-love
-
You make an excellent job!
-
Thanks guys! :-flo
But this must be a lot better, and the only way to accomplish that,it is the exercise! :-salut
:-wave
-
:-clap :-clap :-clap
Really great :-ok
-
Thank mate! :-flo
-
In the end,it will be something like this... :-think
-
Now it is armed and danger ;)
-
:))
-
I admire you for all that work... I'm not so courageous actually.
-
Oh. I will embarrassed. :-red
Your words are great incentive for me. :-flo
-
Looks quite nice, actually... :-ok
-
Thank mate! :-flo
Now i must finish missiles,fuel tanks,land gear and some other detailes,than i go to the paint!
-
Little progress... :-ok
-
And more little progress... :-ok
As for the small central fuel tank, I had little to shorten, becouse the original was too long. :-roll
-
Must say that you become much skilled with hand brushing :-clap
-
I tried. :-ok :-tri
Thanks :-flo
-
I've done some work these days... :-jump
-
Your skill definitely growing and this look so good :-clap :-clap
-
great work Sall :-clap :-clap :-clap
-
:-clap :-clap :-clap :-clap :-clap
-
Thanks guys! :-flo
-
the paint work is sooo nice! :-clap
-
Thanks mate :-flo
Some details are added. :-jump
Painted the nose of the aircraft, part of the intake air, the details of the vertical part of the tail, and the area around the engine - and the engine(that I forgot to shot)
-
And little more...
-
Wow! Hey Sall you improved much comparing to you first model. Bravo! :-clap :-clap :-clap :-clap :-clap :-clap :-wave
-
The End :-joke
-
Yes :-ok :-clap
-
Nice one :-ok :-clap
-
Well done!
-
Wow! Sall is "riding on the wild side" :) great man :-jump :-flo :-clap :-clap :-clap :-clap :-clap :-clap :-wave
