Changes to Mexican Aviation...

Untill I have time to get around to editing the actual posts...


Curtiss-Mexico is a wholly-owned subsidiary of the Curtiss-Wright Corporation, servicing all Curtiss engines in Mexico and producing some components for spares etc. It undertakes no design or research and development work of its own. Its only engines are both Curtiss products developed in the USA;
- V-1520 Conqueror
- V-1720 Emperor

Talleres Nacionales de Construcion Aerea (TNCA)
This is the largest of the Mexican aircraft constructors and has been in business since the 1920s. It has links to Focke Wulf in Germany, PZL in Poland, and Douglas and Curtiss in the USA. This company is the main manufacturer of aircraft, with a sizable state stake in the funds but also with 49% of its shares sold to other investors. Focke Wulf and Curtiss have substantial stake in the firm.

Name: TNCA Pinguino O-8 Shipborne Scout
Revised Specs: N/A
Notes: Nothing to change

Name: TNCA Pelicano P-1 Patrol Flying-boat
Foxy says: “That design is getting canned.”

Name: TNCA Coyote B-7 Light Bomber
Revised Specs: No changes needed
Notes: TNCA assembled these planes using kits supplied by Douglas; they and are a variant of the Douglas B-7 as used by the USAAC. The engines are supplied from Curtiss-Mexico, the first ever built by the firm; they used a majority of US-supplied components.

Name: TNCA Condor B-1 Medium Bomber
Notes: This project is scrapped; it is unnecessary given other Mexican bombers, and is technically unworkable to fit a bomb bay onto a C-47.

Name: TNCA Tololoche C-1 Fighter
Revised Specs:
Size: Wingspan - 31ft; Length - 21ft; Wing area - 170sq ft
Weight: Empty – 2,050lbs; Max take-off – 2,700lbs
Performance: Max speed - 185mph at 8,000ft
Ceiling - 27,000ft
Range - 400 miles
Climb - 1,890ft/min initial climb.
Notes: Just revised specs.

Name: TNCA Quetzalcoat) C-3C Fighter/Bomber
Revised Specs:
Size: Wingspan 32ft; Length - 21ft; Wing area - 200sq ft
Weight: Empty - 2500lbs; Max take-off - 3600lbs
Performance: Max speed - 250mph
Ceiling - 27,500ft
Range - 400 miles
Climb – 2,400ft/min initial climb
Armament – 2x 0.3in MGs and one 250lb bomb under the fuselage
Notes: Two support struts on each side of the wings.

Name: TNCA Quetzalcoat C-3I Interceptor
Note: This aircraft is scrapped. The fifteen aircraft supposedly built are re-ordered as repeated C-3C fighters.

Name: TNCA Mapache A-1 Ground Attack
Revised Specs: Two .3in machine guns, 2x 250lb bombs under the wings on two bomb racks, total weight 500lbs only. No rockets.
Notes: No other changes.

Name: TNCA Aguila C-5 Halcon Fighter
Revised Specs: Engine is a Curtiss-Mexico built 700hp Conqueror and is un-supercharged
Size: Wingspan - 30ft; Length - 25ft; Wing area - 200sq ft
Weight: Empty – 3,000lbs; Max take-off – 4,100lbs
Performance: Max speed - 270mph
Ceiling - 25,000ft
Range - 450 miles
Climb - 2000ft per minute
Notes: TNCA developed this aircraft from the Curtiss P-23 with the assistance from Curtiss engineers. This is therefore not a totally home-grown design, but gave the TNCA designers (including Angel Lascurain) some valuable lessons and experience in design with less risk by basing the fuselage structure and aerodynamics on a proven platform.

Name: TNCA C-5 Aguila I+
Notes: This design is scrapped, with the order transferred to the standard Aguila I (for a total of 45 planes).

Name: TNCA C-10 Aguila II Fighter
Revised Specs: This plane is revised to become of an improvement on the basic Aguila I. TNCA develops its own inward-retracting undercarriage system based on that of some foreign designs. This requires the two .30in wing MGs to be moved a little further outboard. No 25mm cannon are fitted. The magazines are still within the wing. The Aguila II carries the same Curtiss V-1570 Conqueror engine as the Aguila I, being built by Curtiss-Mexico.
Size: Wingspan - 30ft; Length - 25ft; Wing area - 200sq ft
Weight: Empty – 4,000lbs; Max take-off – 5,100lbs
Performance: Max speed - 290mph
Ceiling - 25,000ft
Range - 450 miles
Climb – 2,020ft per minute
Armament: Four 0.3in MGs (two wing and two upper cowling)
Notes: The Aguila II is a modified Aguila I with the only major change being the undercarriage and inner wing structure. The 1,000lb weight increase is for the new undercarriage, revised inner wing structure, pneumatic equipment and radio.

Name: TNCA C-11 Aguila III Fighter
Revised Specs:
Armament: One 25.4mm cannon firing through propeller hub, two 0.3in MGs in the wings. No bombs.
One Curtiss-Mexico Emperor V-1720 1,100hp with a single-stage supercharger
Size: Wingspan – 30ft; Length – 28ft 9ins; Wing area - 200sq ft
Weight: Empty – 5,900lbs; Max take-off – 7,300lbs
Max speed - 330mph
Ceiling - 30,000ft
Range - 500 miles
Climb - 3,100ft per minute
Notes: Another TNCA development of the Aguila II, this aircraft uses the same wing and a new forward fuselage forward of the cockpit which is now enclosed. The Curtiss V-1720 engine was US developed, made under licence but Curtiss-Mexico. The ventral radiator is reshaped and moved a little further aft, though the cockpit is not moved. No Talons Special model was ever constructed. The use of the Aguila II wing means it is still a little unstable, but it saves R&D and re-tooling costs.

Name: TNCA licence-built Focke Wulf FW 187M/ M+/ M++ C-17/ C-18/ C-18R Long-Range Fighter
Revised Specs: M+ Specs; Max speed 399mph; climb 1,750ft/min rest unchanged.
Notes: The 30 Fw-187M fighters are built largely from Focke Wulf supplied kits in a new production line separate from the Aguila line. All 30 have the licence-built Curtiss-Mexico 700hp Conqueror V-1570-23, un-supercharged.
The Fw-187M+ and M++ are merged into one type, the M+. These are built with less Focke Wulf supplied parts but are still partially supplied in kit form from Germany. TNCA and Curtiss work together to fit the new Curtiss V-1720 engine into the Fw-187, so all the M+ aircraft get the new Curtiss-Mexico Emperor V-1720 1,100hp with a single-stage supercharger. The C-18R is a long-range modification with an extra fuel tank in the fuselage and no cannon in the nose, these being the first totally Mexican built aircraft, delivered during 1940.

Name: Gothia Works GW Type 105M C-15
Revised Specs: None needed as basic specs of GW Type 105 are fine, see below.
Notes: Since TNCA is already involved in two fighter production programmes and has no spare resources all Type 105 aircraft are imported from Gothia Works. There are no Mexican-built C-15s at all and all have the 1,300hp GWM V-1300 engine.
Foxy said: “All of those got resold to Romania.”

Name: TNCA/PZL C-9 Tornado/Jastrzab Fighter
Revised Specs: None needed, no air-ground rockets
Notes: While it was claimed this was a further development by TNCA of the C-3 and A-1 family this is definitively false. TNCA and PZL split the programme 50/50, TNCA designs the fuselage using knowledge gained from all its work so far and PZL develops the wings.

Name: TNCA C-13 Aguila V
Notes: Terminated. This project is unworkable in any sense by the Mexican aircraft industry within the next seven years. A second batch of Aguila III fighters should be ordered instead.

Name: TNCA B-18 Relampago Light Bomber
Notes: Terminated. This project is unworkable in any sense by the Mexican aircraft industry within the next seven years. An improved B-23 model, which would fill Mexico’s needs most economically and logically, should be built if necessary.

Name: TNCA C-19 Cobra Fighter
Notes: Terminated. The Bell P-39 and P-63 were reclaimed by US player, and these planes were therefore P-39s purchased from the United States.

Name: TNCA E-1
Notes: Terminated. This project is unworkable in any sense by the Mexican aircraft industry, and all pulsejet work is stopped as unworkable by Mexican know-how. The Moderators have repeatedly made their position clear on this.

Name: TNCA Tailless Programme
Notes: Terminated. This project is unworkable in any sense by the Mexican aircraft industry within the next ten years. Any such aircraft will be totally derived from US research and aircraft if and when they choose to share that technology with Mexico.

Name: TNCA Pulsejet Fighter Programme
Notes: Terminated. This project is unworkable in any sense by the Mexican aircraft industry within the next ten years. All pulsejet work should be stopped as unworkable in any sense during this period. The Moderators have already made their position clear on this and the technical analysis only confirms these opinions.

Name: Powered Bomb
Notes: Terminated. This project is a waste of TNCA’s valuable R&D resources which they should be channelling into an Aguila IV fighter, or other aircraft types like the A-10. This is not a cost effective method of bombing, while the base aircraft is easily built and could be based on the O-1 the navigation and radio systems would be hard for even the US to perfect without building dozens of prototypes and using a lot of funds. The state of the Mexican radio industry is unknown but not thought to be that advanced.

This firm is a wholly-owned Douglas Corporation subsidiary, create for and run by Douglas for the sole purpose of supplying the Mexican market with its products. This firm handles sub-assembly of all DC-2, DC-3 and C-47 aircraft needed by Mexico using Douglas supplied kits. Note: The Azcarte developed 10-man glider is moved to Aviacion Mexicana. As a subsidiary of Douglas, they do not directly compete with their parent company (particularly in foreign exports).

Name: Azcarte B-23 Dragon Medium Bomber
Revised Specs: none needed
Notes: This is the standard Douglas B-23 Dragon, built from US supplied kits with some minor fabrication of control surfaces etc. A newer version with improved R-2600 radials is possibly under construction using Douglas-supplied parts from 1940, in order to replace the B-18.

Name: Azcarte T-5 Airliner
Revised Specs: None needed, extra range is a result of an extra fuel tank to meet Mexican specifications.
Notes: This is the Douglas DC-5 built under licence from Douglas supplied kits with some minor fabrication of control surfaces etc. It enters production in mid-1940 to coincide with Douglas’ own production of the new type for the US and world markets.

Name: Azcarte B-28 Super Dragon Medium Bomber
Notes: Terminated. This project is unworkable in any sense by the Mexican aircraft industry within the next ten years. Azcarte instead should build an improved B-23, or Mexico could purchase and import North American B-25 bombers (subject to the US player’s acceptance).

Aviacion Mexicana
This company is a smaller division of TNCA for the sole purpose of building the O-1 Toucan, O-3 Saltamontes and the ten man glider. It has no design team of its own but solely produces smaller TNCA products and components for its larger fighter production lines. There is a single small factory.

Name: TNCA Toucan O-1 Long Range Scout/Battlefield Observation
Revised Specs: None needed
Notes: No changes other than the caveat that the full 500lbs bomb load is only carried over a shorter distance and not the full radius. Designed by TNCA but built by the new company Aviacion Mexicana.

Name: TNCA O-3 Saltamontes light observer and liaison aircraft
Revised Specs: None needed
Notes: Designed by TNCA but built by the new company Aviacion Mexicana.

Name: AM A-10 Javalina Ground-Attack aircraft
Revised Specs:
Armament: Two 25.4mm cannon and four 0.3in MGs in the nose, 1,000lbs of bombs but no air-ground rockets
Size: Wingspan - 47ft; Length - 32ft; Wing area - 310sq ft
Weight: Empty - 9,000lb; Max take-off - 11,200lb
Performance: Max speed - 250mph
Ceiling - 29,000ft
Range - 350 miles
Notes: No 47mm cannon is fitted, that is impossible in this timeframe and of dubious utility. The unspecified engines need to be firmed up. The armoured aircraft for maritime patrol is terminated. The massively altered recon variant is similarly terminated (the C-18R provides a better platform allied to the O-1 and O-3). Since Aviacion Mexicana does not have its own design team, this design, its development and construction is moved to TNCA, using the winding-down Fw-187 production line, as the TNCA A-10.
