Qual será o estado deles?
Se estiverem bons, por mim, podia embalar tudo com fita azul e dourada e entregar lá em São Pedro da Aldeia (mas revisados)

[Carlos Lima]

Acho que existem todos os tipos de estado... esses estão com cara de ser os "F" que estão sendo retirados de serviço.

A MB vai preferir sem dúvida os novos que está encomendado pois são bem mais modernos do que os "F" que se não me engano nem capacidade ASV possuem .

(edited - digitei errado e troquei ASW por ASV )... ups!!!

SH-60F Seahawk

After the SH-60B entered service, the Navy began development of the SH-60F to replace the SH-3 Sea King. Development of this variant began with the award of a contract to Sikorsky in March 1985. An early-model SH-60B was modified to serve as a SH-60F prototype. The company was contracted to produce seven SH-60Fs in January 1986 and the first example flew on 19 March 1987.

The SH-60F serves as the carrier battle group's primary antisubmarine warfare (ASW) and search and rescue (SAR) aircraft. The helicopter hunts submarines with its AN/AQS-13F dipping sonar, and carries 14 sonobuoys. The SH-60F is unofficially called the "Oceanhawk".

The SH-60F can carry Mk 46 torpedoes, Mk 50 torpedoes, or Mk 54 torpedoes for its offensive weapons, and it has a choice of fuselage-mounted machine guns, including the M60D, M240D, and GAU-16 (.50 caliber) for self-defense. The standard aircrew consists of one pilot, one co-pilot, one tactical sensor operator (TSO), and one acoustic sensor operator (ASO).

U.S. Navy orders unmanned, underwater mine-clearing craft to sweep Persian Gulf amid fears of imminent attacks on oil platforms from Iran
By JAMES NYE
PUBLISHED: 03:43 GMT, 12 July 2012 | UPDATED: 15:07 GMT, 13 July 2012

The U.S Navy is transporting dozens of unmanned underwater craft to the Persian Gulf to help locate and destroy mines in anticipation of a military conflict with Iran and the closure of the Strait of Hormuz.
The tiny SeaFox, four-foot long submersibles are equipped with an underwater camera, sonar and an explosive charge and have been urgently requested by Marine General James Mattis, the top U.S military official in the Middle East.

Each $100,000 submersible is designed to be either detonated near mines in the water or to detonate the mines themselves by ramming them.

A $100,000 SeaFox submersible: A large number of the unmanned underwater craft have been
dispatched to the Persian Gulf in anticipation of a future conflict with Iran

They are deployed by helicopters or small boats and can operate up to 1,000 feet deep and can travel at speeds of up to six knots.

The request for the highly specialised unmanned craft comes as negotiations with Iran over its nuclear program seemingly grind to a halt.

In three rounds of talks since April between Iran - which claims it is pursuing nuclear power for civilian means - and the five permanent members of the U.N Security Council and Germany have produced little progress.

However, while the European Union oil embargo and sanctions make their effect felt in Iran, some U.S. officials worry that the Islamic Republic might lash out by launching or sponsoring attacks on oil tankers or platforms in the Persian Gulf.

The Mine countermeasure ship USS Avenger: The U.S. Navy has increased the number of
Avenger class minesweepers in the Persian Gulf from four to eight in recent months

Officials in Tehran have threatened to close the narrow Strait of Hormuz before, thereby affecting up to a fifth of the oil traded worldwide.

The first batch of the SeaFox unmanned submersibles have already been deployed to the Persian Gulf along with four MH-53 Sea Dragon helicopters.

In addition, the U.S. Navy has also doubled the number of minesweepers in the region as it prepares for a military conflict with Iran.

The four Avenger-class vessels arrived in Bahrain on June 24 to counter the threat of Iranian midget-submarines, which 'are a huge problem for us,' according to retired Navy Commander Christopher Harmer, who from 2008 to 2009 was the director of future operations for the U.S. Navy Fifth Fleet.

Iranian submarines participate in a naval parade: The U.S military is worried about the capabilities of
Iran's fleet of small submarines that are capable of laying mines and disrupting the oil trade

'They are a threat to us because they can disperse them throughout the Persian Gulf and the Arabian Sea and its extremely difficult for us to track them,' said Harmer to the Christian Science Monitor
'As a result they can lay in wait to execute an ambush.'

While the U.S. Navy is well practiced tracking larger submarines, searching for smaller units is not something they have had to do.

'Looking for small subs in shallow water is much more difficult, because the acoustics are so much more difficult - smaller makes less noise,' said Harmer.

With 19 of these submarines estimated to be in service, the Iranian navy is expected to add another four each year.

The USS Enterprise is one of two American aircraft carriers in the Persian Gulf region

The USS Abraham Lincoln is also in the vicinity to protect shipping through the Strait of Hormuz

The capabilities the submarines possess most feared by the U.S. military are their ability to quickly and stealthily lay down mines and also potentially get near to the enormous aircraft carriers that are positioned in the Persian Gulf.

The United States already has two aircraft carriers, the USS Enterprise and USS Abraham Lincoln in the region, with two army brigades stationed in Kuwait and a squadron of F-22 fighters.

While clearly prepared for an escalation in the nuclear stand-off with Iran, analysts are pessimistic for a resolution.

'I think it’s almost inevitable that the military tensions in the Gulf increase,' said Michael Singh, former senior director for Middle East affairs at the National Security Council to the Christian Science Monitor.
'I think that it’s natural on one hand to see Western policymakers giving more serious thought to the use of military options to bolster our position in the Gulf.'

Eu,sou da opinião que a MB poderia obter por oportunidade uns 10/12 exemplares(revisados).Estes complementariam os S70 novos do HS-1.O HS-1 vai ficar com poucas unidades. Devemos lembrar que os S70 foram compradas com o próprio orçamento da MB,infelizmente não houve apoio do GF em um financiamento internacional.

Eu acho que o bixo vai pegar desse ano para o próximo lá na região hein.

Irã em alerta, situação na síria, Rússia engrossando a voz, RT dando uma atenção extrema para a região e cada dia que passa maior, senadores americanos cada vez com discursos mais agressivos.

Now this is the beginning of the end.

Cool.

Lockheed Martin realiza teste com o míssil de cruzeiro anti-navio LRASM.

Acima o míssil AGM-158 JASSM

A companhia americana Lockheed Martin realizou recentemente um exitoso testes do sistema de detecção de alvos do novo míssil de cruzeiro anti-navio da empresa, o LRASM (Long Range Anti-Ship Missil), desenvolvido em conjunto com a DARPA (Defense Advanced Research Projects Agency) para a Marinha Americana.

O míssil LRASM foi lançado por um aviação comercial Sabreliner modificado e logrou detectar e identificar todos os alvos movendo-se em distintas alturas e velocidades, disse o comunicado da Lockheed Martin.

Como já fora dito, o míssil foi desenvolvido com o apoio da DARPA e teve como protótipo o míssil de cruzeiro ar-superfície AGM-158 JASSM (Joint Air-to-Surface Standoff Missile, que atualmente está em uso pela Força Aérea Americana, Força Aérea Real Australiana, Força Aérea Finlandesa, Força Aérea Real Holandesa e Força Aérea Turca.

O míssil LRASM está dotado de um dispositivo de sensoriamento que detecta navios em uma zona determinada, um sistema optoeletrônico para identificar e designar os alvos e um módulo de GPS para detectar e destruir navios dentro de um grupo de batalha naval.

As características técnicas do míssil ainda são desconhecidas. Seus testes finais, segundo se prevê, serão finalizados no começo de 2013.

O AGM-158 JASSM, por sua vez, já tem as características técnicas reveladas. Esse míssil pode levar uma ogiva de até 450 kg e destruir alvos a uma distância de até 450 km.

O modelo anti-navio precisará levar mais sensores então certamente terá uma ogiva menor, mas não deve baixar tanto assim dos 450kg deste AGM-158.

Esta é a tendência dos mísseis anti-navio lançados de superfície de projeto atual, alcances acima dos 300 Km e ogivas acima dos 250 Kg. Outra tendência é a alta capacidade de manobra e sensores múltiplos (e lá se vai a esperança no soft-kill, mesmo que se consiga enganar ao mesmo tempo os sensores de radar e de imagem o míssil simplesmente faz a volta e tenta de novo até acertar em alguém). E em alguns projetos tem também as velocidades supersônicas ou mesmo hipersônicas.

Isso permite situar onde estaremos quando a versão naval do MAN-1 (alcance de ~70 km, ogiva de 165Kg, orientação apenas por radar e subsônico) ficar pronta.
