Se a verba para a Forca é pouca, mais ainda deveria gastar com meios que evitassem a redundância e sobreposicão com outra Forca, (o EB).
Foi esse tipo de argumento que deixou a MB e o EB sem aviação por anos, e hoje vemos que ele está equivocado.
Eles podem ser o mesmo equipamento, mas a missão e completamente diferente, não que um não possa ajudar o outro se necessario, mas cada força com o seu.

E quanto a possível sobreposição de forças, o amigo sapao já falou o que eu penso, cada um com suas missões. Exemplo, ainda falta muito para um VANT do EB fazer uma designação laser para uma esquadrilha de A-1, por exemplo, bem como levantar alvos de superioridade aérea e confecção dos relatórios de reconhecimento (REMIR) classe 3, com a definição dos DMPI...
A MB opera com asas fixas embarcado e o EB opera seus helis com a funcão principal de assalto aeromóvel, ligado a Bda Aerotransportada ou a uma divisão. Nesse casos, não há redundância. Mas elas exitem nas Forcas Armadas: os próprios projetos de pesquisa de VANTs são tocados no CTEx (vide o último informativo de agosto desse ano:
http://www.ctex.eb.br/jornal_ctex/jornal_016_ctex.pdf
e no DCTA. Redundância. Aliás, o fato da FAB querer 12 VANTs táticos é mais outro sintoma da falta de sintonia entre as Forcas.
Citei o exemplo o SARVANT, no inicio da página, que mapeia 500KM^2 em 30h. Em similitude, um Hermes 450 poderia cobrir mais de 200Km^2, que é sua área de atuacão em apenas 12h. Outro ponto: o H450 é considerado VANT divisionário, pelo próprio fabricante, e é utilizado pelo British Army, e estranharia o fato do EB não considerá-lo um VANT adequado para ele :

Business Overview
Principal Activities
We develop, manufacture and integrate advanced, high-performance defense electronic and electro-optic systems for customers throughout the world. The Company focuses on designing, developing, manufacturing and integrating command, control, communication, computer, intelligence, surveillance and reconnaissance (C4ISR) network centric systems, including unmanned vehicles, for defense and homeland security applications. We also perform upgrade programs for airborne, land and naval defense platforms, often as a prime contractor. Moreover, we develop and manufacture avionic and aerostructure products for the commercial aviation market. In addition, we provide a range of support services.
Our major areas of operations include:
• military aircraft and helicopter systems and upgrades;
• helmet mounted systems;
• commercial aviation products;
• unmanned air vehicle (UAV) systems;
• naval systems;
• land vehicle systems and upgrades;
• command, control, communications, computer and intelligence (C4I) and government information systems;
• military communications systems and equipment;
• electro-optic and countermeasures systems and products;
• homeland security systems;
• electronic warfare (EW) and signal intelligence (SIGINT) systems; and
• technology spin-offs and other commercial activities.
Many of these major activities have a number of common and related elements. Therefore, marketing, research and development, manufacturing, performance of programs, sales and after sales support often are conducted jointly among these areas of activities.

Se a FAB precisa de designadores Laser, o EB também, com seus misseis MSS1.2, que também são previstos na utilizacão pelo Pantera:
Nada contra a FAB ter um par de Hermes 450 para desenvolver a doutrina, mas 12, é desperdício de dinheiro. A atividade de reconhecimento tático, pode ser feito pelos futuros VANTs do EB, ficando os estratégicos para a FAB.
Thor escreveu:Não sei de onde vieram esses números, mas a diferença de velocidade de cruzeiro, que é o que importa para traslado e até mesmo operação, entre os VANT é pequena, variando entre 70 a 110 kt, a exceção do Global Hawk e do Reaper, que são outra categoria.
Ok, então vamos estabelecer a velocidade de cruzeiro o H450 (70kts-~130km/h) como padrão e utilizar uma a'rea a 800Km de distância para ver quanto tempo cada um pode permanecer no local:
Hermes 450: ~ 7:30 min
Hermes 900: ~27: 30 min
A diferenca de 20h. É enorme.
Utilizando o H450 de modo estratégico, devido ao fato de ter metade da autonomia do H900, ele terá de sair da área muito mais vezes que o H900, gastando um tempo de trajeto que é inútil.
