Japan confirms developing an electromagnetic railgun
According to a press release, Japan’s Acquisition, Technology
& Logistics Agency has revealed that they are indeed developing a
new electromagnetic railgun.
On 31 July, Acquisition,
Technology & Logistics Agencyhas released video footage showing
a prototype of electromagnetic railgun for the first time. This is the
first official confirmation of the development of a program a new
generation of weapons systems for Japan Self-Defense Forces.
Details
of the Japanese railgun programme have not yet been made available. It
is noted that this electromagnetic railgun weapons system may be
outfitted aboard on next-generation destroyers, possibly the Type 27DD.
The railgun
utilizes a combination of electric and magnetic force to fire a
projectile by means of a sliding armature that is accelerated along a
pair of conductive rails. The railgun uses a pair of parallel
conductors, or rails, along which a sliding armature is accelerated by
the electromagnetic effects of a current that flows down one rail, into
the armature and then back along the other rail.
The
electromagnetic railgun is capable of firing a projectile 100 miles away
and has a low cost of projectiles compared to conventional weaponry.
On
top of the reduction in costs per projectile, the railgun limits the
need to maintain a large quantity of heavy explosive tipped shells,
increasing safety on board navy vessels, and reducing logistics costs
and needs. Ships at sea can afford to stay out for longer periods
without resupply, reducing the burden of at sea replenishment
operations.
Misaka es muy buena dando cañonazos con monedas, pero si la USN tuvo problemas y de momento ha renunciado al railgun no veo en que pueda ser diferente un desarrollo japonés.

Un tesoro de minerales raros en Japón podrá cambiar la economía mundial
Una de las complicaciones más grandes para las industrias es que los
mineralesno son infinitos. La Tierra tiene una cantidad dada de ellos y
cuando se termine, tendremos que ver nuevas formas de generar
tecnologías. Pero Japón está más tranquilo en lo que a esto se refiere
ahora que un grupo de científicos encontró un suministro enorme de minerales raros. Pero esto no es solo importante para la industria japonesa, sino que podría cambiar la economía mundial.
Algunos de estos minerales son usados para construir los elementos
tecnológicos que más se venden, como son los smartphones o las baterías
para los autos eléctricos. Sin embargo, en este momento China tiene una
gran parte de los yacimientos, por lo que la economía de otros países
depende de este país. Ahora que Japón también tiene un suministro,
podría cambiar el comercio en general en esas regiones del mundo.
¿Qué nos dice el estudio publicado?
El estudio
fue presentado en la revista Nature y habla sobre este increíble
yacimiento japonés. Se trata de minerales que contienen uno o más de los
17 elementos metálicos raros de la tabla periódica. Si bien están
presentes en la corteza terrestre, generalmente están demasiado
dispersos como para encontrarlos tan aglomerados en un solo sitio. China
tiene la ventaja hasta ahora, marcando los precios en el mercado, por
eso este descubrimiento es tan importante.
Con los suministros encontrados hay un total de Itrio para 780 años, Disprosio para 730 años, Europio para 620 años y Terbio
para 420 años. Se encuentran en la isla Minamitori, con exclusividad de
Japón para su extracción. No es casualidad, ya que el país estaba
buscando un yacimiento así desde hacía tiempo.
¿Cómo se generan estos minerales?
Es posible que se formen con la actividad volcánica, pero la mayoría
existe gracias a las supernovas, incluso desde antes que existiera la
Tierra. Luego pasaron a formar parte de la superficie de nuestro
planeta. Debido a la actividad tectónica los minerales fueron
acercándose más a la superficie, pero dispersándose con el tiempo.
Aunque es una gran noticia para Japón, todavía hay
un problema. Extraerlos es costoso y bastante difícil, así que tendrán
que estudiar formas de llegar a ellos gastando la menor cantidad de
recursos. De todas formas, es una noticia muy importante para la
economía mundial.
Pues te equivocas Andresk, si tiene que ver y mucho puesto que si lo logran explotar bien, seria un respiro para su economía (recuerden es el país mas endeudado del mundo), y por ende les dará para seguir subiendo el presupuesto de defensa, y seguir costeando proyectos como el de Misaka
Los japoneses parece que se han cansado de lidiar con el Mitsubishi F-2 y ya están determinados en construir su reemplazo.
Japan has decided to build a new fighter to replace the F-2
Defense Ministry to develop own fighter jet to succeed F-2, may seek int'l project
The Ministry of Defense
has decided to develop a new aircraft to succeed the F-2 fighter, as
proposals from three American and British companies for a replacement
failed to meet the ministry's costs and capability requirements,
government officials told the Mainichi Shimbun.
The
ministry plans to incorporate the project into the next five-year
mid-term defense program to be drawn up at the end of the year, with an
eye on a joint development program with foreign companies to lower the
overall financial burden, which could reach trillions of yen. The
ministry also hopes to pursue introducing main components such as the
engine that incorporate Japan's own technology.
As many as 92 F-2s are owned by the Air Self-Defense Force, and will
begin to reach the end of their service life in the 2030s. The quick
adoption of a replacement plan is necessary as developing a fighter jet
can take 10 years or more. In response to a government call for
proposals, three American and British manufacturers made offers to
upgrade their existing models -- Lockheed Martin for its F-22, Boeing
for its F-15, and BAE for its Eurofighter Typhoon.
However, refurbishing the stealthy, state-of-the-art F-22 is
expensive, and "no clear explanation was given about the possibility of
the U.S. government lifting the export ban" on the aircraft, according
to a senior ministry official. The two other proposals also failed to
meet the ministry's requirements.
The remaining option is domestic development, which has the backing
of defense industry groups and some ruling Liberal Democratic Party
lawmakers seeking to preserve the production and maintenance platforms
for Japan's fighter jets. However, a number of challenges including
extremely high costs and a lack of sufficient development experience on
the part of Japanese companies are still obstacles for the project.
The ministry has invested some 190 billion yen so far to conduct a
technical study on the engine and electronic system for a
next-generation fighter jet from fiscal 2009 through 2018, but the
developed engine is still being tested to determine its basic
capabilities and no plan is set for a flight test.
The government is therefore seeking to share the financial burden
with British or German-French partners as they are also looking into
developing next-generation jets. But an international program could lead
to difficulties in coordinating differing requirements for the
deadline, capabilities and distribution of tasks. The United States,
Japan's national security ally, has just introduced new F-35 fighters
and has no immediate plan for their replacement.
Some in the Ministry of Defense have proposed making a decision
about an outline for the new development of the jets at the end of the
year, deferring a decision on whether it should be a domestic project or
joint undertaking with foreign companies. Under the proposal, Japan
will advance domestic technological development while continuing to
negotiate with potential foreign partners.

Interesante, creo que con el conocimiento que tienen con el F-35 deberían mandarse rapidito a hacer el F-3, a que termina pareciendose a un F-35 de dos motores ¿No les servirá una asesoría de Northrop?

The 11th Soryu-class submarine, SS-511 Oryu, was launched at the
Mitsubishi Heavy Industries shipyard in Kobe on October 4th. Oryu
features one significant design upgrade: It is Japan's first submarine
powered by lithium-ion batteries.

MHI to build two new multirole frigates for JMSDF
Japan’s defense ministry has awarded Mitsubishi Heavy
Industries a contract to build the first two of a new class of multirole
frigates for the Japan Maritime Self Defense Force (JMSDF), the
shipbuilder announced on November 1.
Mitsubishi Heavy Industries (MHI) announced on 1 November that it has
been awarded a contract by the Japanese Ministry of Defense (MoD) to
build the first two of four ships of a new class of multirole frigate
for the Japan Maritime Self-Defense Force (JMSDF).
Although MHI did not disclose the value of the contract, the MoD had
earmarked JPY92.2 billion (USD816 million) in its budget for fiscal year
2018 for the construction of the two 130 m-long, 13 m-wide frigates,
which are expected to be handed over to the JMSDF in March 2022.
In August the MoD requested JPY99.5 billion from Tokyo for the
construction of the two remaining vessels, with delivery expected to
take place in March 2023. However, the contract for these two ships has
yet to be awarded.
MHI’s frigate design and proposal were selected over those submitted
by Mitsui Engineering and Shipbuilding (MES) and Japan Marine United.
MES, however, was chosen to be the subcontractor.
Construction of the first 3,900 tonne ship will take place at MHI’s
Nagasaki Shipyard & Machinery Works in Nagasaki Prefecture, while
the second one will be built at MES’s Tamano Shipyard in Okayama
Prefecture. The arrangement marks the first time that MHI will build a
ship as the lead contractor.
According to the MoD, this new frigate class, which is intended to
carry out surveillance missions in waters surrounding the Japanese
archipelago, will be equipped with enhanced multirole capabilities,
including the ability to conduct anti-mine warfare operations, which
until now have been performed by the JMSDF’s ocean-going minesweepers.
Armament on the frigates, each of which will be capable of embarking
one helicopter as well as unmanned surface and underwater vehicles, is
expected to include the navalised version of the Type-03 (also known as
the ‘Chū-SAM Kai’) medium-range surface-to-air missile, a 5-inch (127
mm)/62-calibre gun, a vertical launch system, canister-launched
anti-ship missiles, and a SeaRAM close-in weapon system.
¿Se acuerdan de la intención de Japón de hacerse con 100 F-35 más y que se comentó en el tema de Estados Unidos?
Pues bien, de esos 100, 40 serán F-35B VSTOL. Y Japón se prepara para modificar sus Izumo Class, aunque informa que también los apostará en las islas de Okinawa y Senkaku.
Japón ya no es un país imperialista, pero tampoco se la van a dejar montar de los chinos o de los rusos. El lógico que si China hace sus portaviones, pues Japón también va a hacer los suyos; incluso podría pensar que a futuro no tendría nada de raro que los japoneses pueden montarse en un programa de misiles balísticos/crucero/antibuque de muy largo alcance para tener su propia estrategia A2/AD con que contrarrestar a la de China.

Que nos manden los F-2 a la FAC, aquí los recibimos con los brazos abiertos, jejejeje.
Auf Wiedersehen.
Ni a palos.
