We have topics on several of the aircraft in this list, and attempts at identifying missing numbers in places, but no complete list in one single topic, so I thought this could be a good idea. Since it's the "Designations" section here, I'm only giving the basic info for identification purposes, but it's always possible to develop one or several projects in the appropriate section.

The history of Argentine aircraft production is very complicated to understand because of the way the official engineering and production entities have been renamed, taken over, merged, even sold, over the years. The Fábrica Militar de Aviones (FMA) was created in 1927, and produced all aircraft from then onwards. The Instituto Aerotécnico (Institec) was created in 1943 as a development unit, and in 1944, FMA became a division of Institec. As a result, all the aircraft projects carried "I.Ae." designations. In 1951, Industrias Aeronáuticas y Mecánicas del Estado (IAME) was created, and both Institec and FMA became a part of it. In 1957, the aviation activity of IAME became DINFIA (Dirección Nacional de Fabricaciones e Investigaciones Aeronáuticas), which lasted until 1967, when it became AMC (Área Material Córdoba). Although Institec still existed as a separate entity until 2009, the Fábrica Militar de Aviones (FMA), now as a division of AMC, lasted until 1995, when aircraft production was sold to Lockheed Martin to become Lockheed Martin Aircraft Argentina S.A. (LMAASA). In 2009, Lockheed Martin sold it back to Argentina, and it became the Fábrica Argentina de Aviones « Brigadier San Martín » S.A. (FAdeA). Have I lost you along the way? You're excused, it's all such a complicated mess!

General information on the FMA and FAdeA can be found in these English and Spanish language Wikipedia pages:

- A "Tipo El Palomar" replica was produced by DINFIA in 1962.
- The Fw 44J sometimes appears as the "Jilguero", although it seems to be a translation of "Stieglitz" and not an official name.

There is no indication that there ever were other numbers allocated to any other designs or projects, although it is possible that the early "Ae." aircraft may have been given such numbers internally.
- Only the designs that were built are in bold type.

Further versions were developed locally by AMACUAR/Aerocuar throughout the 1980s, and designated M-5 Finger IIA, Finger IIIA, Finger IIIB and M-5P Mara. They were modified from the earlier production.

Thanks hesham.
Great additions, the I.Ae. 49 and I.Ae. 52, thanks for these. I've added the info to the list.

Thanks a lot, Hood! I'll add this to the list. ;)
But before I do that, do you have a source for this type? I could find no mention on it anywhere.
Just a scan of a page where it's mentioned would be enough. Thanks!

Just checked. It can be found in several places, but here's the best one, from La enciclopedia de ciencias y tecnologías en Argentina:
Download can take a while though, not because it's a 25,84 MB file, but because their server appears to be very slow...
 
Can anyone clarify concerning the different using of the abbreviations

IA-
I Ae-
I.A.
I.Ae. ???

Holding Las Alas de Peron II in my hands, I'm confused by author's erratic using of IA-... and IAe-...

The heading for the Pulqui II (on page 64) is IA-33, inside the text (e.g. p66) he uses I Ae-33 (with blank character!), and on the tail of the 4th prototype (contemporary picture on p81) I can read IA 33. There are more examples for an inconsistent notation of the abbreviation. Any idea of the background or even the correct spelling?
 
All of them are correct :eek:

The official designations changed several times in a matter of years. It was almost as if each new government decided to change the company name at will and the various designation prefixes changed overnight.

I too have noted that the official designations changed and that the authors have used them because there is nothing else available.
 
My dear Boxkite;

the FMA (Fabrica Militar de Aviones) formed in 1927,and in 1943 redesignated Institute
Aerotecnico,during 1952 incorporated into Industrias Aeronauticas y Mecadnicas del Estado,
and in 1957 became Direccion Nacional de Fabricaciones e Investigaciones Aeronauticas,
and reverted to FMA in 1968,so the many prefix belong to a period of those.
 
IA-68 ATL Light passenger transport project supposed to be produced in the 1980s (197?)

There were two projects with the IA-68 designation, the ATL transport (1982) and i 1984 the Advanced Attack Aircraft (AAA).

IA-66 Pucara II Improved version of IA-58 for Fuerza Aérea Venezolana with Garrett TPE331 turbines (1981)
IA-67 Córdoba Twin-boom high-wing transport project (197?)

The IA-67 Cordoba is from the same year as IA-66, I should check my books.

The IA-66 was re-engined with the assistance of the American company Volpar, which offered the IA-67 Cordoba to FAA. The IA-67 used wings, engine, nacelles and two rear fuselages from the Pucara to obtain a transport aircraft very similar to the IAI ARAVA.

Based on IA-67, VOLPAR presents its proposal for the ATL to the FAA, then IA-68, which was an enlarged IA-67. The local proposal presented by the Aeronautical and Space Research Institute (IIAE - Instituto de Investigaciones Aeronáuticas y Espaciales ), which was more advanced and promising than Volpar's, was preferred.

SAIA 90 Supersonic Air Superiority jet fighter (198?)

The SAIA 90 was "officially" launched in 1981, but it never went from being a wet dream of the Argentine Air Force (FAA). Most of the renders or three views of SAIA 90 that circulate on the Internet are actually representations of Dornier's different projects. prior to FCA and Eurofighter

This Air International article of 1978 mentions that the IA-60 was an advanced jet trainer. Above it is mentioned that the IAe-60 was a Subsonic shoulder wing T-tailed light bomber project, designed by Héctor Eduardo Ruiz. Could they be the same. It was not uncommon to use a jet trainer as a double for light bombing.

This Air International article of 1978 mentions that the IA-60 was an advanced jet trainer. Above it is mentioned that the IAe-60 was a Subsonic shoulder wing T-tailed light bomber project, designed by Héctor Eduardo Ruiz. Could they be the same. It was not uncommon to use a jet trainer as a double for light bombing.
IA-60 was an advanced trainer and light attack platform powered by two Astafans, conserving the basic airframe layout and canopy of the Pucará with T-tail but incorporating high wings. Some tests were made on wind tunnels but no further development was made in order to proceed with the IA-63 Pampa program.

That's right, they were the same aircraft, not two different projects.

The IA-60 was an advanced training jet and a light attack aircraft. It was planned to complement and later replace the A-4 Skyhawks of the Argentine Air Force

There were three projects powered by Astafan turbojets

The first two are from 1969, when the project was still known as Delfin / Dolphin :

"A twin-jet aircraft for photography and aerial observation".

"A twin-jet aircraft for photography, observation and light transport"

03_IA-58-Pucara-Birreactor-Transporte.jpg


Both did not pass the preliminary draft stage

Then in 1970 Dr Reimar Horten presented the project of a Pucará for advanced training missions and as a replacement for the Morane Saulnier MS 760 Paris. This variante was shortened in length and span.

Obviously this project did not arouse interest in the FAA as a replacement for the Morane Saulnier MS 760 Paris used for advanced training, since it did not advance beyond the theoretical studies and preliminary calculations of weights and performances.

A note about the Pucara powered by tubojets that I wrote a few years ago. It is in Spanish:

Might be good to explain the abbreviations? I.Ae. means "Instituto Aerotécnico" for example.
 
This is a repost from this thread but its technically relevant to the topic of FMA designations. I looked into the Pulqui II prototype names and found this: https://archive.org/stream/alan_147/SAFO 144_djvu.txt
If this text is correct then most books and sources about the Pulqui II are incorrect, with only 4 complete prototypes being made.
  1. E-1- first prototype, armed with four 20 mm MG-151 cannons. First flight: June 16, 1950. Crashed: May 1951.
  2. E-2 - second prototype, initially unarmed and planned for static tests but was later modified to become flight worthy when the E-3 crashed in 1952. The modification was done in 1953 and included: first fitting of the planned armament of four 20 mm HS 804 cannons, one wing fence per wing, four trakes on the tail, air brakes, increased fuel capacity from 2,000 to 3,000 liters (as per E-3), strengthened landing gear (as per E-3), in-flight adjustable rudder (as per E-3). This modification is what i believe most people call "prototype 04" and the "prototype 02m" (modified), etc. Crashed 1956.
  3. E-3 - third prototype, unarmed. Modifications from E-1: increased fuel capacity (2,000 to 3,000 liters), strengthened landing gear, in-flight adjustable rudder. First flight: early 1952. Crashed october 1952.
  4. E-4 - fourth prototype, never completed with parts going into the E-5.
  5. E-5 - fifth prototype, completed in 1959 using parts from E-4 and E-6 as the final Pulqui II. It is called "Pulqui IIe" at times but was equal to the final E-2 but without armament. First flight: May 1960. Given to "Museo Nacional de Aeronáutica de Argentina" at the end of 1960.
  6. E-6 - sixth prototype, never completed with parts going into the E-5.
 
A comment about Ae.M.B. 1 / 2 (Aerotecnica, Militar Bombardero). Production was 15 airplanes and at the begin all were designed Ae.M.B.1 and focused in bombing task. As soon as AeMB1 Bombi were born they were outdated, and they have some problems with landing gears.
Problems were fixed, tourrets wiped off, and LG was modified. Also role was different, parachute, observation. Those were redesigned as AeMB2.
Full side views is a AeMB1, nose detail is a AeMB2.

Can anyone clarify concerning the different using of the abbreviations

IA-
I Ae-
I.A.
I.Ae. ???

Fabrica Militar de Aviones had different names through his history.
-1927 - 1943 Dirección Nacional de Aeronáutica del Ejercito gave names like Ae.M.B1 (..Aeronautica..Militar, Bombardero #1)
-there are two examples around 1940 called FMA 20 & FMA 21, which means Fabrica Militar de Aviones
- 1943 - 1955 Instituto Aerotécnico gave denominations like I.Ae. 27 Pulqui I
-1955 -today Names are just IA
Last IAe was IAe34 and first IA was IA 35 Huanquero

Hope this clarify your question
 
I.Ae. 43 Pulqui III Supersonic delta-wing hunter-interceptor project designed by Kurt Tank (1954)

Such a useful and fascinating thread. By the way, did some Pulqui III made it into the HF.24 Marut ? the plane flew in 1961 but Kurt Tank was snatched by Nehru right after Peron fall, in 1955-56.

And how long did Reimar Horten stayed in Argentina ? without his brother obviously, do we know why only one of the brothers went to Argentina and stayed there ?

Reimar Horten stayed in Argentina until his death in 1993, always living in Córdoba. He had offers to go to work in the US but his wife, who was born in Argentina, asked him to stay in the country where she was born.

Horten continued to participate in various FMA projects. He participated, among many other projects, in the four present in the article below.

In IA-63 Pampa he had no intervention

The Horten missile, the Pucará Jet, the IA-60 jet trainer and the IA-68 advanced attack – Argentine projects that we would have liked to see in service

In the years prior to the military coup that overthrew President Peron, the government decided to invest in car factories, agricultural machinery, refrigerators, kitchens, etc., to increase domestic consumption and continue to industrialize the country.

The Pulqui II, despite the fact that it was presented at every aeronautical show in the country, gradually lost relevance in military budgets. Added to that was the growing inflation that was shrinking the salaries of German engineers and technicians. Before the coup, the Hindus began to offer Tank a lot of money to go to India to work, and after the coup, seeing the situation in the country, he decided to emigrate to that country.
 
After reviewing this and several other topics, I realized that the main list contained a few mistakes and omissions.
I'm going to address them here one by one, and will later update the first post accordingly. Here is the first part of this review:
  • Slots -20 and -21 were designated F.M.A-20 and F.M.A.-21. The prefix "I.Ae." appeared only with I.Ae.22, but there is a confusion about that because when the F.M.A.-20 was reengined with the more powerful 75hp Continental engine (instead of the original 65hp), it was indeed designated I.Ae.20-B.
  • A second version of the I.Ae.22 was produced with a 475hp Armstrong Siddeley Cheetah engine and a two-blade constant-speed Rotol propeller; it carried the designation I.Ae.22-C, or DL-22C, and 100 were ordered (likely included in the 206 grand total).
  • The I.Ae.23 was nicknamed the "Focke-Wulf de Madera", refering to its building up on the Fw 44 J design.
  • There is a lot of confusion over the I.Ae.26, as it was designated the D.600 by Dewoitine. Indeed, that designation also applied to a Spanish single-seat fighter of different shape, and a transport project back in France. Several depictions of a would be "I.Ae.26 "Aguja" found online are NOT accurate and PURELY FICTIONAL.
  • The I.Ae.27A/B "Pulqui II" was a weird-looking proposal by Italian designers Morchio and Riccardi, competing with Kurt Tank's I.Ae.33.
  • The I.Ae.28 designation was used for the so-called "Super Calquín", a twin-engine light attack bomber with R-R Merlin III engines, abandoned in favour of I.Ae. 30 Ñancú; elsewhere, it is said to have been used for Dewoitine's D.710 design, an eight-passenger transport project; I'm not 100% certain but they might be one and the same design.
  • The I.Ae.29 was a single-seat jet fighter project with straight wings, lower nose intakes, designated D.720 by Dewoitine; it was abandoned with the development of the I.Ae.33.
  • The I.Ae.30 Ñamcú was considered for development by Italian designer Pallavicino as a twin-jet heavy fighter and light bomber, often called "Pallavicino I" and Pallavicino II", although the never received any official designation.
  • Horten's so-called "'Caza sin cola" single-seat tailless flying-wing fighter project never received a proper designation, but was refered to in some documents as "Expediente S339/49".
  • One I.A.34 Clen Antú (also known as the Horten XVa) was modified for testing of unconventional control surfaces and designated I.Ae.34-B; the single-seat version was designated I.Ae.34-M (or Horten XVb).

As of 1951, all new designs were prefixed "I.A." instead of "I.Ae.". This was to reflect the fact that the FMA (Fábrica Militar de Aviones) was now part of Industrias Mecánicas del Estado (or IAME).
  • The I.A.35 Huanquero (initially called "Justicialista del Aire") was not produced in large quantities, but had quite a few variants: Type 1A (Advanced instrument or navigation trainer), Type 1B (bomber), Type 1U (bombing and gunnery trainer), Type II (light transport/liaison), Type III (air ambulance), Type IV (photographic reconnaissance), as well as three variants considered different enough to deserve a new name: a small executive transport called the Constancia (which is sometimes described as the same as Type II, and sometimes given as a separate Type V), the Pandora (a different executive transport version, designated I.A.35-X-III), and the Guaraní (I) (initially called the Constancia II), a transport with Turbomeca Bastan turboprops; all of these were I.A.35 and had H-tail configuration.
  • The I.Ae.36 Cóndor (II) (note old style designation as it was drafted in 1951) was a Kurt Tank design that can also be found in some documents as the Pentaturbo.
  • The I.A.37-P delta-wing glider prototype was to be followed by an I.A.37-E jet trainer version, but this was abandoned.
  • The I.A.39 was a short-haul airliner project based on an I.A.35 airframe.
  • The I.A.40 is supposed to have been a night fighter project, but no details or images seem to exist. However, some sources insist that what many sources now call the I.A.43 Pulqui III interceptor was in fact designated I.A.40. Although there is no evidence to support that theory, the fact that I.A.43 was also used for a very different design invites caution.
  • The I.Ae.41 project was built as the I.A.41-L Urubú, and received the Horten XVc designation, since it was a development from the I.Ae.34 series.
  • The I.Ae.42 was a four-engine passenger transport project, a larger development of I.Ae. 39; several configurations were studied until 1956, probably all pertaining to the "42" slot.
  • The I.A.43 designation was initially assigned to a 1953-54 four-seat delta-wing project; however, the designation is often quoted as refering to the Pulqui III, a 1956-57 swept-wing supersonic delta-wing hunter-interceptor project designed by Kurt Tank, which other sources give as the I.A.40.

Both FMA and IAME eventually became part of the larger DINFIA (Dirección Nacional de Fabricaciones e Investigaciones Aeronáuticas) in 1957, until 1968 when FMA regained its name, now as a division of AMC (Área Material Córdoba), which replaced DINFIA.
  • The I.A.50 designation was first given to an eight-passenger executive transport project; when this was cancelled, the designation was reused for the Guaraní II, a single swept fin development of the first Guaraní. It was frequently just refered to as the G-II. Several versions were studied: ASW, bomber and commuter transport (the latter two as Guaraní III and G 3), as well as an IA-50A maritime patrol version, but none of these were produced. Eventually, the remaining examples were upgraded circa 1987 and redesignated as IA-50B G II.
  • The I.A.51 designation was first given to a strange-looking tandem-seat COIN project; however, it was reassigned to the Tehuelche, an all-metal derivative of the I.A.46 Ranquel which remained a prototype. The COIN project was redesigned and reassigned as I.A.55. The fact that the latter is also found as a basic trainer project may simply be a misinterpretation of its tandem-seat configuration, or more likely a confusion with I.A.57.
  • DINFIA's I.A.58 Pucará program was eventually produced under AMC as IA-58A (note the new syntax). Later prototype versions were designated IA-58B, -58C, -58D, etc. up to the current IA-58H.
  • The IA-59 was a straight-wing regional jet transport project by Horten, not to be mistaken with the IA-X-59 Dronner, a high-wing twin-fin UAV prototype, also called the Tábano (like an older bomb type).
  • The designation IA-60 was assigned twice: first to a tandem-seat jet-powered derivative of the Pucará, and later to a subsonic tandem-seat shoulder wing T-tailed advanced jet trainer/light attack, none of which was built.
  • The IA-61 project was a photo-observation/light transport derivative of the Pucará with pressurized cabin and extended range.
  • The IA-62 designation applied to two quite different primary trainer designs: one was the continuation of the previous I.A.51 and I.A.55 COIN designs; the other had a more conventional configuration.
  • There exists great confusion in this thread and elsewhere about the designations IA-67 and IA-68. Although most sources agree that the Córdoba twin-boom high-wing light transport project was designated IA-67, the designation for the later ATL (Avión de Transporte Liviano) is often given as IA-68. However, no documents seem to support this, and the only time a designation is actually given for the ATL, it is IA-67 as well.
  • The IA-68 project was the Advanced Attack Aircraft (AAA), derived from the "IA-63 Avanzado" project.
In 1995, the FMA division of AMC was sold to Lockheed Martin and became Lockheed Martin Aircraft Argentina S.A. However, the only new models were produced under that identity were upgrades of the Hercules, Skyhawk, Pucará and Pampa aircraft. Lockheed Martin sold that branch back to the Argentine state in 2009, when it became the Fábrica Argentina de Aviones « Brigadier San Martín » S.A., better known as FAdeA. Under that new identity, the IA-73 Unasur I primary training aircraft was studied as a replacement for the T-34 in Latin America, but only a mockup was built. It was replaced by the IA-100 basic trainer and technological demonstrator, which will be produced from 2024 as the slightly different, simplified IA 100B Malvina.

One I.Ae.22 was modified with a 475hp Armstrong Siddeley Cheetah engine and a two-blade constant-speed Rotol propeller, and carried the designation I.Ae.22-C...

According to the Aviones en Argentina site, the I.Ae.22-C DL was also a production type - with a second series of 100 x Cheetah XXV-engined 'DL-22C' aircraft being ordered (E.a.-801 to E.a.-900). That would make the aircraft shown in reply #34, the third production airframe of the second series.

-- https://avionesenargentina.com/1er-vuelo-del-i-ae-dl-22/

Most sources seem to agree that a 2-bladed, constant-speed Rotol was used with the Cheetah-powered aircraft. Despite this, Wikipedia has captioned a photo of an I.Ae.22 thusly: "I.Ae.22C DL, with Armstrong Siddeley Cheetah 25 engine and 3-blade Rotol propeller". In reality, this photo depicts the experimental installation of an Alvis Leonides.

-- https://upload.wikimedia.org/wikipedia/commons/b/b1/IA22.jpg

Alas, the photographed aircraft bears no E.a. number so its exact identity is not obvious. I believe that the prototype was originally flown with a Wright Whirlwind (before its domestic El Gaucho engine was ready). But, I'm unclear as to whether E.a.700 was also the test bed for the Leonides.

Elsewhere, there is a cryptic mention of the fifth production aircraft - "Solo el Ea-705 (de la primera serie), utilizó dicho motor". Does that refer to the Alvis installation? Or does that mean that E.a.-705 was flown first with the I.Ae. R-16-SD1 El Gaucho before having a test installation of the Pratt & Whitney Wasp - a fourth engine type associated with the I.Ae.22?

Anyone else as confused as me?

Awesome! Thanks for the correction, I'll gladly update the info (you may or may not have noticed that I've completely updated the original list in the first post, by the way).
