antes de diminuir/aumentar contingente eu gostaria de ver um dia a MB e o Executivo separarem a função de guerra da guarda costeira.
È uma ancora na MB que atrapalha demais a organização da força.
Depois ai sim reorganizar o quadro de efetivos e temporários de acordo com o planejado.

World first: Cruise ship Viking Grace to harness wind power with century-old tech
In addition to its LNG engines, Viking Line's passenger ferry Grace will cruise using the power of a newly-installed rotor sail for the first time on Thursday.
Viking Line's flagship cruise liner Grace has received an upgrade this week. On Tuesday ship workers in Turku installed a mechanical rotor sail on the vessel that is expected to significantly conserve fuel and reduce carbon emissions.
According to the Åland-based cruise firm, Grace will be the first passenger liner in the world to use the rotor sail technology. The rotor sail is developed by Finnish firm Norsepower and is expected to reduce Grace's carbon emissions by up to 900 tonnes per year.
Compared to many other cruise ships that run on diesel around the world, Grace — fuelled with liquid natural gas (LNG ) — is already relatively environmentally-friendly. The vessel has traversed its island-dotted routes through the archipelago between Turku and Stockholm, Sweden since 2013.
The principles behind the rotor sail technology itself is not new and actually about a century old, but the company said the need for more environmentally friendly power options has brought it back into use.
“This is a great day for us. As an Åland shipping company, we rely on the sea for our livelihood so it’s of prime importance for us to promote the well-being of the marine sea. We want to pioneer the use of solutions that reduce the environmental load," Viking Line CEO Jan Hanses stated in a company announcement.
How does it work?
The extra power that the 24 meter-tall and four meter in diameter rotor sail provides is a result of a physics phenomenon known as the Magnus effect.
When the rotor spins, passing air flows at a lower pressure on one side than the opposite side, Viking Line explained in a press release on Wednesday.
"The propulsion force created by this pressure difference will drive the vessel forward. The rotor sail operation is automated and the system will shut down in response to any disadvantageous changes in the direction or force of the wind," the company elaborated.
Norsepower has been developing its rotor sail tech for the past five years and Viking Line said that it plans to use more of its rotors on its next passenger ferry which is currently being built in China. The yet-to-be-named ship will be equipped with two of Norsepower rotor sails and is expected to be operational sometime in 2020.
Vendo os editais da MB dos concursos para aspirantes a oficiais e para o Colégio Naval para ocorrerem no final deste ano, houve uma redução de 13,7% do número de vagas.
Quanto aos oficiais temporários, teremos de esperar o decreto-lei do ano de 2019 para comprarmos com este ano.

14/06/2018 ThyssenKrupp considera vender unidade de construção naval após perda de contrato
Mas nem observadores vamos mandar?
No mais, vamos mandar o que pra lá?
A Barroso? Que na prática, é o único navio 100% que temos?
As Amazonas? Acho que é um navio modesto demais para o poder que "achamos" que temos e queremos mostrar.

Um pouco de hombridade e honestidade não faz mal a ninguém.
Admitir que não temos condições de participar de um exercício como esse já foi um grande feito para o orgulho da MB.
Se conseguirmos ir a UNITAS deste ano já vou achar bom até demais.

Não vamos na RIMPAC mas também não estaremos parados, a Barroso estará na África do Sul para o Atlasur.
Tunisian Navy commissions latest Damen OPV and locally built patrol boat
Mrityunjoy Mazumdar - Jane's Navy International
05 July 2018
The Tunisian Navy commissioned its second Damen Multi Service Offshore Patrol Vessel (MSOPV) 1400 and a third Istiklal-class patrol boat at the port of La Goulette on 25 June.
Syphax (P 611), the second of four MSOPV 1400s on order for the Tunisian Navy, was delivered to Tunisia the previous month after completing construction at Damen’s shipyard in Galati, Romania, on 2 May. First-of-class Jugurtha was delivered in early March.
Built to Bureau Veritas classification standards, Tunisia’s Damen MSOPV 1400 vessels have a length of 72 m, a 12.7 m beam, and a 3.75 m draft. The vessels have a standard displacement of 1,284 tonnes or up to 1,877 tonnes fully loaded.
Powered by two Caterpillar engines, with a total power rating of 7060 kW, the nominal top speed is 20 kt, but this limit has been exceeded on sea trials with speeds approaching 22 kt. So far, no heavy weapons have been fitted.
Meanwhile, the third OPV, Hannon , commenced initial sea trials in the Black Sea on 26 June.
Tecnologia para construir o reator eles tem, agora colocar num casco de TR 1700 abandonado a 25 anos parece mirabolante.
Eu acho muito interessante o conceito de reator que eles desenvolveram, acho inclusive que deveríamos adotar esse conceito (uma parceria, já que temos cascos??), me parece bem interessante para submarinos de patrulha em mar aberto como o Atlântico sul. Não é ideal para caçar submarinos ou esquadras nucleares a alta velocidade, mas para negação de mar e vigilância e até mesmo espionagem, me parece bem mais interessante que AIP. Por ter resfriamento por convecção, deve potencialmente ser mais silencioso que um Subnuc tradicional.
Umas unidades de Scorpene BR+ com esse pequeno reator... desenvolvemos e testamos em parceria com os Argies um protótipo para eles financiado pelo BNDES e depois construímos para nós e ajudamos a construir os deles. Poderia até se chamar Classe Paraná, uma bacia sedimentar que dividimos, Whisfull thinking...
