Marinha do Japão

[FCarvalho]

O Japão ao que parece terá novamente os seus fuzileiros navais. Terão de ter então meios para que possam lança-los. Isto explica em partes o conceito acima apresentado. Se será maior que o Izumo, que por si já é bem grande, só o tempo dirá.

Ainda aposto em uma futura classe de Nae convencionais para a marinha nipônica.

Pelo menos nos próximos 10 anos eles vão estar ocupados com a renovação da frota de superfície e da aeronaval.

Mas por volta de 2025~2035 poderá aparecer algum projeto de Nae.

Japan's planned buy of Ospreys gets State Dept. OK
Japan's planned procurement of V-22 Osprey military transport aircraft has received State Department approval, Congress was told.
By Richard Tomkins | May 6, 2015 at 11:16 AM

WASHINGTON, May 6 (UPI) -- A request from Japan to procure V-22B Osprey tiltrotor military transport aircraft from the United States has received approval from the U.S. State Department.

The possible deal for 17 Block C Ospreys -- together with spare parts, associated equipment and logistics support -- would be through the U.S. Foreign Military Sales program and is worth an estimated $3 billion.

"Japan is modernizing its transport fleet to better support its defense and special mission needs," the U.S. Defense Security Cooperation Agency said in its required notification to Congress. "The proposed sale of V-22B Block C Osprey aircraft will greatly enhance the Japan Ground Self-Defense Force's humanitarian and disaster relief capabilities and support amphibious operations. This sale will promote burden sharing with our ally and interoperability with U.S. forces."

DSCA manages the FMS program.

The V-22 Osprey is jointly manufactured by Bell Helicopters and Boeing Rotorcraft Systems. It is a vertical takeoff and landing aircraft that flies as a fixed-wing plane and is used by the U.S. Marine Corps and U.S. Air Force. It has a speed of 241 knots at sea level, a range of 879 nautical miles.

In addition to the 17 aircraft, the proposed sales package for Japan includes 40 AE1107C Rolls Royce Engines, 40 AN/AAQ-27 forward looking infrared radars, 40 AN/AAR-47 missile warning systems, 40 AN/APR-39 radar warning receivers, and 40 AN/ALE-47 counter-measure dispenser systems.

Identification friend-or-foe systems, AN/APN-194 radar altimeters, AN/ARN-147 VHF omni-directional range instrument landing system beacon navigation systems, and other systems are also part of the deal.

Bell Helicopter and Boeing Rotorcraft Systems, via a joint venture arrangement, would be principal contractors and U.S. government or contractor representatives would be required in Japan on a temporary basis for program technical support and management oversight.

"It is vital to the U.S. national interest to assist Japan in developing and maintaining a strong and ready self-defense capability," DSCA said. "This proposed sale is consistent with U.S. objectives and the 1960 Treaty of Mutual Cooperation and Security (with Japan)."

Como se chamam as Tropas Anfíbias da JDF? Pertencem ao Exército ou à Marinha?

[akivrx78]

As forças anfíbias pertence a força terrestre eles chamam de Suiriku Kidoudan mas o treinamento tem participação da força marítima e força aérea também.

Nestas fotos que acima tem fotos da JGSDF Western Army Infantry que tem um batalhão em Sasebo e desde 2002 recebem um treinamento básico de fuzileiros.







Aos poucos eles estão montando um corpo de fuzileiros navais, os primeiros carros de um lote de 52 comprados do Eua chegou no inicio do ano.






Eles pretendem ter 3 batalhões em 3 locais diferentes totalizando de 2000 a 3000 fuzileiros os primeiros devem ficar baseados em Sasebo, neste mesmo local eles tem um batalhão tipo forças especiais com mais experiência chamado de Yamaneco Butai (batalhão gato selvagem) com uns 900 homens especializado em infiltração, sabotagem, guerrilha.

[mmatuso]

E a constituição vão mudar mesmo?

Japão voltará a ter F.A. "completas" e vão agir também fora do japão?

[FCarvalho]

O que acontecerá com esta força de infantaria naval do exercito com a criação dos fuzileiros navais, que provavelmente serão ligados a marinha nipônica? Integração, desmobilização?

abs

[akivrx78]

Pelo que se comenta os fuzileiros não vão ser transferidos para marinha eles vão continuar como parte do exercito, no Japão as 3 forças trabalham em conjunto as vezes compartilhando os centros de treinamento.

A Msdf tem uma companhia de 100 membros tipo comandos (Tokubetsu Keihitai) para se ter um contingente maior tem mudar a constituição mudando o nome de forças de defesa para forças armadas, já que fuzileiros são meios ofensivos.

[FCarvalho]

Bem, mudar parece ser a palavra de ordem em matéria de defesa no Japão hoje.
A ver.

[akivrx78]

Estas alterações levam um tempo somente para levantar a proibição de exportação de armamentos o assunto consumiu uns 6 anos de debate, para aprovar a lei para poder atuar fora do território japonês e a da defesa coletiva se discute o assunto faz uns 4 anos mesmo assim ainda precisa ser aprovado alguns pontos pendentes este ano.

O PM japonês esta sendo muito criticado pela oposição no momento, além da popularidade cair 10 pontos por causa das mudanças em assuntos militares.

Todas as pesquisas publicas reportaram que 60% da população é contra estas mudanças, mas por ter maioria no parlamento eles lentamente estão conseguindo realizar estas alterações.

A Mitsubishi apresentou um novo desenho para o FFX 3000t.


Em 2009 foi apresentado este desenho que foi reprovado pelo alto custo.


Em 2013 a TRDI apresentou este desenho que foi muito criticado.

No mesmo ano foi anunciado o interesse pela classe Independence mas o assunto parece que morreu.

Agora a Mistsubishi apresentou este novo desenho.

Mitsubishi Unveils Japan’s Future 3000 Ton FFX Frigate

Japan's Mitsubishi Heavy Industries (MHI) has unveiled a new surface combatant concept for the Japan Maritime Self-Defense Force (JMSDF) next generation 3000 tons class Frigate known as "30FF" or FFX in its latest "Defense and space domain briefing", Navy Recognition reported Friday.

The Japanese MoD said in the mid-term defense program that there is need for compact hull Destroyers (known as DEX).

According to the program, the vessels appears to be fitted with an integrated mast with several planar arrays for radar(s), a 5 inch (127mm/L62) main gun, two remote weapon stations between the bridge and the main gun, and what could be a Phalanx CIWS on top of the helicopter hangar.

This concept may be the future replacement for the JMSDF older classes of surface combatant such as the 4,900 tonnes Asagiri class and the 4,000 tonnes Hatsuyuki class.

Mitsubishi eyes technological leap, and exports, with armored vehicle

TOKYO | By Tim Kelly and Nobuhiro Kubo

In January, a top U.S. Marine general visited Mitsubishi Heavy Industries in Japan to look at a prototype of an amphibious assault vehicle that could one day be a key pillar in Prime Minister Shinzo Abe's push to sell weapons abroad.

Using engines adapted from the main battle tank the company makes for Japan's military and new water jet propulsion technology, the full-size prototype is undergoing pool tests, although it is in the early stages of development and production could be years off.

Nevertheless, the maker of the wartime Zero fighter plane is eyeing overseas sales after Abe lifted a decades-old ban on arms exports in April last year as part of his more muscular security agenda, two Japanese defense industry sources said.

Mitsubishi designers believe the prototype shown to U.S. Marine Corps Pacific commander Lieutenant General John Toolan will be more maneuverable and faster across the water than the 40-year-old AAV7 amphibious assault vehicle used to carry U.S. marines onto beaches from naval ships anchored offshore, the sources said.

The AAV7 is built by the U.S. unit of Britain's BAE Systems.

The prototype's engines in particular could be fitted onto other armored vehicles, the sources added.

"It's an opportunity for Mitsubishi Heavy to tap overseas markets for its engine technology," said one of the sources, who declined to be identified because he was not authorized to speak to the media.

Mitsubishi Heavy wants to build an amphibious armored vehicle that can move through water at 20 to 25 knots (37 to 46 km per hour) compared to the more than 7 knots (13 km per hour) reached by the AAV7, said the sources.

"If the Japanese can get 20 knots in the water without compromising maneuverability on land, we will be very interested," said one Marine Corps official who saw the prototype in January but declined to be identified.

"Whether that's possible remains to be seen."

A Mitsubishi Heavy spokesman said the prototype had been shown to the Japanese Ministry of Defense, but declined to give details about the vehicle. At a Paris arms show last June, a suitcase-sized model of an eight-wheeled armored troop carrier was the centerpiece display at the company's exhibition booth.

The Ministry of Defense was aware of Mitsubishi Heavy's research into amphibious vehicles but was not involved in the project, a ministry spokesman said.

Manny Pacheco, a spokesman for U.S. Marine Corps procurement, declined to comment on the prototype.

But he said the Marine Corps was "always interested in the technological advances of industry" and encouraged manufacturers to use "every opportunity to showcase their wares and get their products submitted through our competitive procurement process".

TOUGH TECHNOLOGY

Amphibious vehicles are central to marine units around the world, allowing forces to operate on land and sea. But there has been little significant technological advancement in such vehicles in recent decades.

A tracked Expeditionary Fighting Vehicle that was being developed for the U.S. Marine Corps by U.S. weapons maker General Dynamics Corp was canceled in 2011 after big cost increases and technical issues.

The Marine Corps last year kicked off a competition for a new wheeled amphibious combat vehicle (ACV) that could operate on shorelines and shallow water.

Pacheco said the Marine Corps was reviewing proposals from five manufacturers to build a prototype. He did not identify the companies.

A feasibility study by BAE and General Dynamics had recommended against using current technology to build a vehicle in line with Marine Corps requirements, a U.S.-based BAE spokeswoman told Reuters.

"The study concluded that although the technology existed, it would not be fielded at an affordable price," she said.

BAE was talking to Mitsubishi Heavy about being a potential partner on the body design of the new Japanese vehicle, the BAE spokeswoman added.

General Dynamics was in similar talks with Mitsubishi Heavy, said sources in Japan. General Dynamics said it did "not have any information to provide at this time".

NEED FOR SPEED

Mitsubishi Heavy has been making armored vehicles for Japan's military for around 80 years, beginning with the Imperial forces in the 1930s. It also builds fighter aircraft, naval vessels, submarines and missiles.

The company also makes high-speed marine engines and water jet propulsion systems, according to its website.

"Japan's technology is good enough that we have to look at it," said a U.S. military industrial source familiar with the amphibious vehicle plans.

Although a coastal nation, post-war Japan only formed an amphibious military unit in 2012. The 3,000-strong unit will be equipped with more than 50 AAV7s.

It was disappointment at the speed of those vehicles over water that spurred Japan to build a new one, Japanese defense officials told Reuters.

Japan's military is also concerned about the ability of the caterpillar-tracked vehicles to ride over coral reefs, a common feature in the East China Sea, where Tokyo is embroiled in a territorial dispute with China.

The BAE spokeswoman acknowledged the desire of the U.S. Marine Corps to increase water speed, adding there should be "no operational concern" with coral reefs.
