Guarani Armored Vehicles: Defense Signs Contract for Production of 86 Vehicles

(Source: Brazilian Ministry of Defence; issued Aug. 7, 2012)

(Issued in Portuguese only; unofficial translation by defense-aerospace.)

BRASILIA --- The Brazilian Army and Iveco signed on Tuesday afternoon the contract for the purchase of 86 VBTP MR wheeled armored personnel carriers, better known as Guarani. The ceremony took place in the Hall of Honor of the Ministry of Defense and was attended by Minister Celso Amorim.

The signing takes place four days after publication in the Official Gazette, the authorization to manufacture a batch of experimental evaluation vehicles, Lot Experiment Doctrinal (LED) of the new armored vehicles, which will allow the restructuring of the Brazilian Army's mechanized forces. The overall value of this initial batch is approximately 240 million Brazilian reals.

These 86 vehicles allow Iveco, the prime contractor, to start production, in anticipation of the Army’s planned acquisition of 2,044 vehicles. The initial Guarani vehicles will be used by infantry and cavalry units of the land force, which will carry out operational trials of the product. Eventually, Guarani is expected to be delivered to the Army at a rate of about 100 units per year over the next 20 years.

Equipement Plan

During the ceremony, the President of Iveco Latin America, Marco Mazzu, said that he was proud to participate in the "renaissance of the defense industry in Brazil." Minister Celso Amorim, in turn, said the start of production of the Guarani marks the implementation of the Defence Organization and Equipment Plan (PAED). He said that it is noteworthy that "the PAED is becoming reality," and that its implementation will contribute to strengthen the Brazilian defense industry.

Amorim also noted that 48 of 86 vehicles under the contract were included in the Growth Acceleration Program (PAC) financing facilities of the Federal Government. Altogether, the Ministry of Defence will receive 1.527 billion reals’ worth of PAC equipment. In addition to the 40 Guarani vehicles, the funds will be used for purchase of 4170 trucks and 30 Astros 2020 missile launch Vehicles. The transfer of the funds money was authorized in late June, through a Provisional Measure signed by President Rousseff.

The Vehicle

Developed with Brazilian technology through a joint project between the Army Technology Center and Iveco, part of the Fiat Industrial Group, the Guarani is a six-wheel drive amphibious vehicle that will serve as the basis for a new family of armored multimission vehicles capable of carrying out reconnaissance and fire support missions.

The new vehicle weighs 18 metric tonnes and will replace the Urutu and Cascavel wheeled armoured vehicles developed in the 1970s by the former Engesa. The main feature of the Guarani is its modular design, allowing the incorporation of different turrets, weapons, sensors and communications systems on the same hull.

By its versatility, the project has attracted the interest of neighbouring countries that are also preparing to re-equip their militaries. During the first half of the year, there were preliminary talks with Argentina, which may initially buy 14 vehicles for use in joint peace-keeping missions with Chile.

The new vehicles will be produced at the factory entirely dedicated to the project, within Iveco’s industrial complex at Sete Lagoas (Mato Grosso state). To date, a single prototype has been officially delivered for testing to the Army Evaluation Center. The large-scale production of the Guarani should begin in early 2013.

According to the forecast of the Brazilian Army, seven armored vehicles will be ready by December this year. They are part of a total of a 16-vehicles pilot batch project. The Operational Experimentation Batch should comprise 38 vehicles by July 2013, and the remaining 48 by July 2014.

According to Iveco, production begins with a proportion of local content above 60%. When the plant is operating at full capacity, it will involve a supply chain in Brazil of about 110 direct and 600 indirect suppliers.

In addition to Minister Celso Amorim and the President of Iveco Latin America, Marco Mazzu, the ceremony of signing the contract was also attended by the Army commander, General Enzo Peri, the Chief of Joint Staff of Armed Forces (EMCFA), General Jose Carlos De Nardi, the head of the Department of Science and Technology of the Army, General James Sinclair Mayer, the Italian ambassador in Brazil, Gherardo La Francesca, and representatives of Iveco, as well as civil and military authorities.

Cette photo montre bien pourquoi les blindés à roues sont souvent plus hauts que les chenillés. Il faut faire passer la transmission.

D'ailleurs c'est quoi le bidule sur le toit? une tourelle manuelle pour mitrailleuse?

C'est quoi les tube verticaux peints qu'on voit sur celle ci, c'est des barres pour rigidifier la caisse?! Si c'est ca ca fait bizarre en plein milieu de la cabine?

C'est bien cette photo que je notais. On y voit en vert sous la caisse le passage de la transmission qui rehausse l'ensemble.

Sur le toit, c'est la circulaire blindée de la version de base, en effet.

f0205060_530afc85b1e6f.jpg

Les trois pylônes internes servent à rigidifier le toit. C'est la version avec la tourelle télé opérée UT30BR de Elbit. Cela montre bien la sensibilité structurelle d'un véhicule, pourtant de 17t, pour porter une simple tourelle télé opérée avec un canon de 30mm.

Je trouve que les nouveaux APC n'ont plus aucun charme, ils se ressemblent tous: Notre VBCI, le Boxer Allemand, le VBTP,le Havoc Américain le Bumerang Russes, etc,etc...

C'est dommage, mais bon si ce type de design permet d'avoir une meilleurs protection autant privilégier cela.

Disons qu'à force d'avoir le moteur au même endroit et de conserver une structure simple pour des raisons de coûts mais aussi d'optimisation des volumes internes, on ne peut pas faire grand chose.

Sinon, un TPz-2 Boxer ne ressemble pas tout à fait au Guarani.

Après dans le cas particulier du VBTP Guarani, celui-ci a une contrainte particulière : la flottabilité. L'armée brésilienne ne voulait pas seulement un blindé qui flotte mais un blindé qui flotte vraiment. D'où son volume très important et sa forme d'étrave.

La seule chose qui puisse changer un peu quelques choses, c'est la transmission électrique, qui "permettrait" de s'affranchir des contraintes de la mécanique de transmission actuel, aussi boite que pont. En gros on peu imaginer des générateur placé n'importe ou, a la place d'un seul moteur, et relié au roue/moteur par des cables électriques qui passe a peu pret n'importe ou. Ca changerait surtout les possibilité d'aménagement intérieur, je doute que la forme autobus elle change. C'est la forme qui permet de transporter le plus de truc dans l'espace réservé par les divers gabarit routier ferroviaire, aérotransport etc. Par ce que la solution les passager derriere, la mécanique devant ca reste l'aménagement le plus protecteur pour les passagers en cas de coup au but par l'avant - normalement le plus probable -.

LEs solution avec le moteur centrale posent des probleme de communication a bord, et les solution avec le moteur arriere pose des probleme de débarquement embarquement, et les solution avec le moteur sous le plancher pose des problème aussi bien avec la transmission mécanique et le refroidissement qu'avec la facilité de maintenance. Reste les générateur distribué dans les "sponson" qui libèrerait l'avant pour y mettre du blindage en plus et quelques accessoire ou réservoir.

Pour compléter ce qu'ecrit G4lly :

On observe une tendance chez les blindés à roues prévus pour le transport de troupe à avoir de plus en plus les flancs verticaux. Avant, ceux-ci étaient inclinés sur l'intérieur (VAB, TPz-1 Fuchs...). Le but était l'allégement de la caisse : En inclinant certaines parois, on diminue leur surface totale ce qui allège le véhicule. De plus, ces inclinaisons contribuent à rigidifier la partie haute. En effet, la plaque de blindage formant le toit étant moins large, elle a moins tendance à se déformer sous son seul poids dans le temps. Rappelons que le toit n'est pas la surface la plus blindée donc la plus épaisse donc la plus rigide. Très souvent on trouve des longerons pour solidifier cette zone. Par exemple, c'est le rôle de la grande barre transversale qui est soudée sur le toit des certains VAB.

Pour le compartiment arrière dans ces cas là, le problème est que tout ce qu'on y rentre (caisse de munitions, outillage, santé, alimentation, eau....) est de forme cubique. Or, avec les angles formés par ces inclinaisons, il y a une grosse perte de volume disponible. Et on s'appercoit que l'on ne range pas grand chose en définitive. Jusqu'aux années 90, cela allait. Mais maintenant, vu l'augmentation du volume de matériel qui doit suivre un groupe, cela n'est plus possible.

Depuis 20 ans, les choses changent grâce à la technique :

1) Les trains de roulement à roues progressent et permettent de porter des caisses blindés plus lourdes. Du coups, à protection constante, les volumes peuvent être supérieurs.

2) La métallurgie progresse aussi et produit des blindages plus légers, plus rigides. Les techniques de soudure progressent aussi.

Tout cela conjugué, les véhicules ont de plus en plus les flancs verticaux ce qui offre des volumes intérieurs plus hergonomiques avec des protections balistiques meilleurs.

Pour suivre cette tendance, il est très intéressant de comparer les blindés qui évoluent par génération. Ils offrent à chaque nouvelle génération plus de volume pour une meilleur protection. On peut citer les XA-180, 185, 186, 188 et enfin 203. Il y a aussi les Piranha-II, III et V (la génération IV n'a pas été commercialisée très longtemps) où c'est particulièrement visible avec le passage du II au III. N'oublions pas la proposition de reconstruction des VAB de RTD sous le nom VAB Mk2. Le seul fait d'avoir des flancs verticaux change tout pour ce dernier.

Pour revenir au Guarani, la finesse du blindage (il faut voir les renforts de toit pour porter la tourelle de 30mm.) permet d'avoir des flancs verticaux très hauts pour avoir la meilleur flottabilité possible.

Livraison du premier lot de VBTP-Guarani :

First Batch of Brazilian Army’s New Armored Vehicle Delivered in Paraná

(Source: Brazilian Ministry of Defence; issued March 24, 2014)

The Brazilian army has received the first batch of Guarani wheeled armored vehicles, developed in conjunction with Italy’s IVECO and which it plans to buy in over 2,000 copies, including special versions. (DefesaNet photo)

CASCAVEL, Brazil --- Since Monday (March 24), the Brazilian Army can count on a modern and powerful tool for military operations including combat, defense, patrol and peacekeeping missions: the Guarani Armored Personnel Transport Vehicle (Viatura Blindada de Transporte de Pessoal, VBTP-MR).

The first batch of 13 vehicles was officially handed over to the 33rd Mechanized Infantry Battalion in Cascavel, in Western Paraná state, in a ceremony attended by the defense minister, Celso Amorim, and the Army commander, General Enzo Martins Peri.

Developed from research undertaken by different units of the Department of Science and Technology of the Army, the Guarani family of armored vehicles is being produced in partnership with the Italian multinational Iveco, which built an industrial facility for this purpose in the city of Sete Lagoas (Mato Grosso state). The intellectual property of the Guarani - which is planned to be exported – belongs to the Brazilian Army.

During the hand-over ceremony of the initial batch, Celso Amorim said that the service introduction of the Guarani "is a significant event and a new milestone in the re-equipping our Armed Forces." To the Minister of Defence, the technological quality and employability of new armored reinforces "the self-esteem of our military" and shows the "future vision" of the Nation.

Amorim said that the Guarani has a large military presence, which ensures a greater deterrent power, "able to deter threats to our territory and our riches." The minister also praised the fact that the project has been developed and produced in Brazil, since its export may result in payment of royalties to the Land Force. "I'm sure the Guarani will be a worldwide success," he said.

Technology

The Guarani will replace the Cascavel and Urutu families of armored vehicles that the military has operated for almost 40 years in the military. It is expected that another 86 vehicles to be delivered by the end of the year to the infantry battalions stationed in Foz do Iguaçu (PR), Apucarana (PR), Francisco Beltran (PR) and the Armored Instruction Center in Santa Maria (RS). "It is a modern and efficient vehicle, a milestone in the transformation process of our troops," said Gen. Carlos Bolivar, who is in charge of the Military Command South (CMS).

For army commander General Enzo Peri, the development of Guarani is a "winning design." The expectation is that over 20 years, 2,044 armored vehicles will be manufactured and delivered to the Land Forces.

With a capacity for 11 men - nine combat troops, a gunner and a driver - Guarani contains, in addition to air conditioning, a number of technological innovations: low thermal and radar signature, which makes its location by enemies more difficult; armored protection against armor-piercing and incendiary ammunition and antitank mines, GPS navigation, ABS brakes, night vision, a 383hp engine allowing a maximum speed of 100 km / h; a battlefield management system, and a system providing situational awareness.

The Guarani is also prepared for swimming, with rear propellers that provide amphibious capability. Its turrets can be equipped with 30mm cannon ammo, as well as .50 caliber and 7.62 mm machine guns. It is designed to engage air and ground targets.

Since 2013, the mechanized infantry battalions in the South and Midwest have received special training to operate the new armored vehicle.

LAAD 2015: Industry hopes for Brazil 8x8 contract this year

17th April 2015 - 15:37 by Grant Turnbull in Rio de Janiero

af51def4.jpg

Industry officials are hoping a contract for the development of an 8x8 variant of VBTP-MR Guarani armoured vehicle will be signed by the Brazilian government later this year, ending uncertainty about the project’s future.

Italian company Iveco has already delivered 174 Guarani vehicles in a 6x6 configuration as part of a contract signed for 2,044 units in 2012. The company will deliver 100 vehicles a year to the army for the next 20 years.

Speaking to Shephard at the LAAD exhibition in Rio de Janeiro, Iveco’s director of research and development for Latin America, Giovanni D’Ambrosio, said he hoped the company would see a contract for an 8x8 vehicle in 2015.

D’Ambrosio confirmed that once a contract was signed it would take at least six years to develop and test an 8x8 prototype to meet the Brazilian Army’s requirement. ‘It will be a completely new design,’ he added.

The Brazilian Army published Basic Operational Requirements (ROB) for a new Medium Wheeled- Armoured Reconnaissance Vehicle (VBR-MR) on 12 September last year. A separate RfP has also been published for the VBR-MR’s main weapon system, which calls for the use of a 105mm gun.

Current plans state that one prototype 105mm gun would be built, a pilot lot of 13 units would then follow and a possible serial production run of around 100 units after that.

D’Ambrosio said because the 8x8 is a different design to the current Guarani 6x6, development work could not begin until a contract decision on the turret and weapon system had been made. ‘We can only start the design [of the 8x8] only after the gun has been chosen,’ explained D’Ambrosio.

Engineering work would be carried out at Iveco’s engineering facility in Sete Lagoas, in the Brazilian state of Minas Gerais.

Four companies are competing to provide the weapon system for the VBR-MR; Belgium’s CMI Defence, Italy’s OTO Melara, South Africa’s Denel Land Systems and China North Industries Corporation.

A consortium made up of OTO Melara, OTO Melara do Brasil and Ares – a Brazilian subsidiary of Elbit Systems – is offering a version of the three man HitFact turret. According to OTO Melara executives, the ‘modular’ 105/120mm gun system would be manufactured by the stated-owned munitions company Imbel.

OTO Melara do Brasil’s president, Gianfranco Pazienza, told Shephard he expected the decision on the 8x8 turret to be made later this year. He confirmed the company had submitted its bid for the contract on March 9th.

Belgium manufacturer CMI Defence – which has had a presence in Brazil since 2004 – has put forward the Cockerill 3000 series 105mm high-pressure tank gun to equip the VBR-MR. CMI Defence told Shephard that its two-man, auto-loaded turret is the only 21st century turret on offer in the Brazilian tender.

A top-level CMI defence official in Brazil said the company had invested significant funds developing detailed plans for turret manufacturing facility in Brazil, which would follow a similar model to facilities already set up in the Middle East, Indonesia and Poland.

Denel will offer a 105mm concept initially developed for the South African military’s Rooikat vehicle.

Cost issues will likely lead to the prototype and initial batch of 13 turrets being manufactured outside of Brazil, whichever company wins the VBR-MR turret tender. OTO Melara said the first batch of HitFact turrets would aim for 20% nationalisation, which would gradually increase to 60% over the project’s life.

Iveco is also competing for a Brazilian Army requirement for 186 4x4 armoured vehicles known as the VBMT-LR. D’Ambrosio said the company is offering its Light Mobility Vehicle (LMV), which is currently in use with the British and Italian Army.

The results of that tender could come as soon as next month. Other competitors include Avibras teaming with Renault Trucks Defense, Grupo Inbra Filtro, BAE Systems Land Systems South Africa and AM General.
