Brazilian 1941 Tender

The FAB is looking to continue its expansion in 1941, therefore all winning tenders from 1940 are to be renewed unless the company involved wishes otherwise. Also, the FAB is looking for a two seat general purpose aircraft, or in other words something that can serve both in the fighter, night fighter, and light bomber/attacker roles. The FAB would like 100 of these. As well the MI wishes to order 60 single seat carrier fighters. All interested parties please also include a delivery estimate.

OOC: Just a note, I thinking of closing the tender in 3 weeks time, but if anyone needs more time just let me know.

France and Chile request more information, having aircraft which could meet one or two of those roles, but not all four, and not with only two crewmen...

France proposes the MB.1050 Milan carrier-fighter, which is currently undergoing acceptance trials and will begin production in February 1941. Delivery of initial units could start as early as April (if the Brazilians order before the end of the year). Any major changes (such as an alternate engine) may be accommodated but will add time due to redesign.

Junkers Ju88D Strike Aircraft Project

The Junkers firm, with the approval of the Defence Ministry, offers the following design as a private venture.

A prototype aircraft can be delivered within 90 days of a decision to proceed; testing can commence immediately thereafter. As the aircraft represents a minimum change from the current Ju88 bomber it is expected that testing would require a relatively short period and that production can be get underway in relatively short order. First deliveries are contemplated within 180 days of an order to proceed.

Description of Proposed Design/Projected Performance

Low-wing cantilever monoplane. Slatted diving brakes hinged beneath front spar and outboard of engine nacelles.

Oval metal monocoque fuselage built up of a number of Z-section frames and top-hat stringers to which is riveted the smooth stress-bearing skin.

Cantilever monoplane-type tail unit. All-metal framework with metal covered fixed surfaces and fabric covered elevators and rudders. Rubber pulsating overshoe type de-icers on tailplane leading edge.

Retractable type undercarriage. Wheels are retracted backwards and turn through ninety degrees to lie flat in lower portions of engine nacelles. Electrically retracted tail wheel.

Two Junkers Jumo 211J twelve-cylinder inverted Vee-type liquid cooled engines each rated at 1,410 hp for takeoff and 1,200 hp at 4,400 metres. There are five self-sealing fuel tanks – four in the wings – two of 324 litres inboard of the engine nacelles and two of 405 litres outboard of the nacelles, and a fifth tank of 1,125 litres in the fuselage bay between the wing spars.

Provision for a crew of two seated in tandem in a fighter-like cockpit in portion of the fuselage forward the front spar. Pilot seated in front, with wireless operator/air gunner in the read position. Crew cockpit is fully armoured and the cockpit is fitted with bullet-resistant glass. Alternative armament proposed

Day fighter/strike aircraft – four 20mm MG201 cannon with 400 rounds per gun fitted in the nose of the aircraft, operated by the pilot; two flexible 7.92mm MG81Z machineguns with 400 rounds per gun fitted at the rear of the cockpit, operated by the wireless operator. Internal bomb cells for two 250 kg bombs or bomb carriers for ten 50 kg bombs. Two external bomb carriers under each inner wing for bombs of up to 1,000 kg or aerial torpedoes, or for fuel tanks. Alternatively, reconnaissance cameras can be fitted in the forward bomb cell.

Night fighter – provision for electronic equipment in the nose of the aircraft per customer requirements. Four 20mm MG201 cannon with 400 rounds per gun fitted in a ventral tray in place of the forward bomb cell, operated by the pilot; two flexible 7.92mm MG81Z machineguns with 400 rounds per gun fitted at the rear of the cockpit, operated by the wireless operator. For night intruder operations, up to four 50 kg bombs can be carried in the rear bomb cell.

Span 20 metres; Length 14.4 metres; Height 4.8 metres; Wing area 54.5 square metres. Normal loaded weight 11,920 kg; maximum permissible take-off weight 13,800 kg.

Maximum speed 500 kph at 4,400 metres. Climb to 4,400 metres 21 minutes. Service ceiling at mean weight 7,800 metres. Range with maximum fuel 3,100 kilometres; range with normal war load 1,200 kilometres.

The canopy covering is certainly small in comparison to the bulk of the aircraft. However, like the Canberra, the canopy merely covers a larger cockpit.

This paper proposal - which has not yet attracted interest from the Luftwaffe - is a minimum change variant, intended to meet the time frame for the Brazilian tender. Whether it meets the FAB's requirements remains to be seen.

Great Britain can offer;

Requirement A (two seat general purpose type)

Boulton Paul feels it has the perfect aircraft for this requirement in its new P.97 Nighthawk now being built for the RAF.
The P.97 is one of the world’s first purpose-built night fighters and was designed as a ‘fresh sheet aircraft’ to incorporate the weapons and equipment to destroy enemy bombers at night and in poor weather. The P.97 two/three-seater is powered by twin Napier Sabre III engines and is armed with six ventral 20mm cannon and a quad .303in Browning powered dorsal turret. Two cannon can be removed and two 250lb bombs fitted on ventral racks to serve as a nocturnal fast bomber. For Brazilian requirements the radio location operators position would be removed. A further ground-attack variant for the Brazilian order could have a new Boulton-Paul designed twin nose turret for strafing ground targets [OOC this turret was planned OTL and resulted in the Shackleton nose turret). Extra bomb rancks would be provided inboard of the engines for a total load of 1,000lbs. The dorsal qaud MG turret could be removed or replaced with a smaller twin-MG turret.
Deliveries could begin within 12 months.
Dimensions; 58.6/ 45.6/ 16.9/ 470 sq ft; 2x 2,300hp Napier Sabre III; max speed 405mph at 34,000ft; range 1,300 miles; rate of climb 3,560ft/min at sea level and service ceiling 36,000ft.

De Havilland offers its brand-new D.H.103 Hornet developed to F.12/40 as a private venture single-seat twin-engined long-range fighter and based on the Mosquito bomber in terms of style and design. It has a wooden monocoque fuselage, very sleek finish and is powered by two 2,375hp RR Griffon II engines with leading-edge radiators. Armament consists of four Orkileon 20mm cannon and racks under the outer wings for either eight RPs or 2,000lbs of bombs or two 200 gallon drop tanks. Internal fuel capacity is 540 gallons and maximum take-off weight is 20,900lbs. The prototype should fly in July 1941 with first deliveries to Brazil from September 1942. Dimensions; 45/ 36.8/ 14.2/ 361 sq ft; 2x 2,375hp Rolls-Royce Griffon II; max speed 472mph at 22,000ft; service ceiling 37,500ft and range 1,500 miles (with drop tanks).

Hawker offers the Henley B.Mk.III. Designed by Sidney Camm to Spec P4/34 and modified for Spec B.1/36. The crew of two are carried in enclosed cockpits, the radio operator operates a twin .303in Vickers mount and the Hurricane outer wings have four 20mm cannon. Four 250lb bombs can be carried (two internal and two underwing) and hydraulic dive brakes are fitted. For Brazilian needs the dive brakes could be omitted.
Dimensions; 47.10/ 36.5/ 14.7 ft; 1x 1,280hp Merlin VI, 330mph, range 900 miles and service ceiling 28,000ft.

Requirement B (Naval Fighter)
Fairey is offering the Firefly; developed to N.8/37 as a new carrier-based single-seat fighter. Powered by a RR Griffon V-12 with a fuselage of exceptionally clean appearance to reduce drag and time to 10,00ft is 3 minutes. Armament is four wing-mounted 20mm cannon and two 1,000lb bombs can be fitted beneath the wings. The latest model on offer is the FN.Mk.II which has a RR Griffon II 2,375hp for 401mph. Deliveries to Brazil could begin in June 1942.
FN.Mk.II: 44.6/ 35.11/ 13.5/ 328 sq ft; 1x 2,375hp Rolls-Royce Griffon II; max speed 401mph at 15,000 feet; range 1,075 miles and service ceiling 30,000ft.

Italy would like to the offer the Caproni 1001 Astore II. This is the most current version in service with the Aeronautica Italiana and differs from the Astore I with the removal of the remote controlled gun position which was found to give unsatisfactory performance. This was replaced on the Astore II by a simple flexible mounting in the gunner's position. It is thought that this aircraft will easily meet Brazil's requirements for a strike aircraft having long range, good speed and a large bomb bay. For a pure fighter role, the aircraft is less well suited. However, Italy is unsure as what Brazil's requirements in the fighter are; It seems unlikely that a twin engined fighter could offer adequate performance in the pure fighter role, especially when the strike role necessitates a larger aircraft, likely 2-man. Caproni's response to the requirement is to bring forwards the adoption of the ventral gun pack. This will fit into the standard bomb bay as a self-contained item. An armament configuration currently envisaged is 4x20mm or 25mm cannon which will be more than adequate for shooting down large bombers such as the B-14. Italy is unable to provide Brazil with an AI radar capability as this time for the night fighter role, and would question the robustness of other types offered in the Brazilian environment.

Deliveries could likely start during the next few months by taking aircraft from the existing production line, but the provision of gun pods would likely take 6-12months. It is thought that this should not present an issue given the time needed to convert onto the type before operational service commences. Brazil would benefit from the large pool of aircraft available on the back of large orders from Italy to replace the SM.79 and 81 and more importantly, the future upgrade plans currently underway: A Serie III version will shortly undergo testing with more powerful AR135 engines to increase speed and maintain survivability against newer fighters. Additionally, a more thorough redesign with entirely new engines for higher altitude performance is currently underway.

Falco II

Falco III

For the naval fighter requirement, Caproni would like to offer their 2001 Falco II which has been in service with Italy for the past few years and recently taken up by Siam. Although the speed and climb are inferior to the most modern types, the manoeuverability is excellent and the ability to carry a torpedo under the fuselage unmatched. The Falco I gives a very useful strike fighter capability and is available immediately. If Brazil is willing to wait 6-12 months, a possible improvement is the movement of the radiators to the wing leading edge position which is estimated to bring with it a 40km/h increase in speed.

Sagittario I

If Brazil is willing to postphone over 12months and accept a slower rate of deliveries, Caproni would offer their 2005 Sagittario I naval fighter currently flying in prototype form. This builds on the experience Caproni has with the Falco I and II and shares many similar features. However, it is an entirely new and larger design based around the Alfa-Romeo 135 series of radial engines. Additional details are available upon request from the Italian Air Attaché.

The Brazilian government thanks all participants of the tender thus far. To answer some of the questions about the general purpose aircraft, this aircraft has been requested to fill three roles that are currently lacking in the Brazilian Air Force, and that the aircraft in question does not have to fulfil those roles simualtaneously. The idea behind it is to have one aircraft with some modifications to it fulfil the night fighter, fighter-bomber, and light tactical bomber roles rather than having three seperate aircraft. The fighter-bomber role is the least important and can be dropped if it hinders the other two requirements, this aircraft was to act as a supplementary to the upcoming EMB-40 (P-47) in the fighter-bomber role, not its replacement.

That is why Boulton Paul is willing to offer different types of the P.97.
Fighter Bomber: Two crew, four lower-fuselage 20mm cannon and four bomb racks for 1,000lb total (250lbs each rack), possible to fit rear MG/cannon armament for self defence
Night Fighter: Two-three crew, six lower-fuselage 20mm cannon and one dorsal turret with 4x MGs (no radio-location nor IR sets would be fitted due to export limitations at this time)
Ground Attack: Two crew, twin 20mm nose turret (like the OTL Shackleton nose), four 20mm fuselage cannon and four bomb racks for 1,000lb total (250lbs each rack).

The FB and NF could share 80% commonality, two 20mm making way for the ventral bomb racks and vice versa.
