, pero yo diría que el Mig si fue un verdadero intento de colarselo a la fuerza aerea rusa, aunque no pasara de prototipo.

Yo no creo sin embargo que si el PAK-FA acaba pareciendose a los ultimos dibujos que corran por la red, y por tanto al Raptor sea por que los rusos hayan copiado el "raptor" simplemente ocurrirá lo mismo que hizo que Hornets, Fulcrums y Flankers sean tan parecidos...
Mismas necesidades, mismo o casi estado de la tecnolgía...

El PAK-FA estará al mismo nivel que un F-22 de ahora, que no significa ser iguales.
Los rusos pues "también" toman nota y de ello la planificación para desarrollar el avión.
Por cierto no viene a cuento los detalles que das pero es igual de valido.

Yo me refiero a que en 1991 (me equivoqué al decir 1986, lo siento!!!), se terminó la competicion entre el YF-22 y el YF-23, y vuelos de prueba. El PAK-FA solo anuncia vuelos de prueba para este año.
Los rusos piensan empeza la produccion para el 2015, mientras que el F-22 este paso lo tuvo en 2003. Además, es muy probable que en 2015 se encuentren con problemas de tener que hacer ya una eventual modernizacion. Además, hay que tomar el tiempo en cuanto tardarán de construir la cantidad "necesaria".
No creo que estoy errado diciendo que USA le lleva ventajas a Rusia en este ámbito con una brecha de... 20 años?
Moscú, 3 de febrero, RIA Novosti. Tres personas murieron este martes al estrellarse un helicóptero militar Mi-24 en la provincia rusa de Sarátov, en la zona del Volga, comunicó un portavoz del departamento regional de Emergencias.
La catástrofe ocurrió a las 11.45 hora Moscú (8.45 GMT) a 18 kilómetros del aeródromo "Pugachov", en la región de Sarátov, precisó por su parte el teniente coronel Vladímir Drik, jefe auxiliar de la Fuerza Aérea de Rusia.
Un grupo de socorristas que se desplazó al lugar encontró el fuselaje quemado y recuperó las llamadas cajas negras o registradores de vuelo que ayudarán a esclarecer las causas del accidente.
El Mi-24 o Hind, en la clasificación de la OTAN, es un helicóptero de combate y transporte que se produce desde 1971 y es conocido en numerosos países.
Irán lanza al espacio su primer satélite de fabricación propia
Reuters (Teherán). .- 03/02/2009 12:50h
Irán ha anunciado hoy el lanzamiento de su primer satélite fabricado en el país, alardeando de un gran progreso en su tecnología espacial mientras continúan las tensiones con Occidente por sus ambiciones nucleares.
El lanzamiento del satélite Omid (Esperanza) podría irritar a la Administración del nuevo presidente estadounidense, Barack Obama, que ha dicho que ve a la República Islámica como una amenaza pero también ofrece diálogo directo con sus líderes.
La tecnología balística de largo alcance utilizada para poner satélites en órbita puede utilizarse también para lanzar armas, aunque Irán dice que no planea hacerlo.
El lanzamiento se produce un día antes de una reunión de las potencias occidentales sobre Irán en Fráncfort. Altos cargos políticos de Estados Unidos, Rusia, Reino Unido, Francia, Alemania y China se reúnen elmañana para discutir el conflicto con Irán sobre su programa nuclear. Será su primer encuentro desde que Obama asumió el cargo.
El Gobierno de Obama ha señalado que tratará de mantener conversaciones directas con Teherán, aunque también ha advertido a Irán de que prevé más presiones si no cumple la demanda del Consejo de Seguridad de la ONU de que paralice el enriquecimiento de uranio. Teherán asegura que sus ambiciones nucleares están limitadas a la generación de energía eléctrica para responder a la demanda de su economía.
Enviar el Omid al espacio es un mensaje al mundo de que Irán es "muy poderoso y tienes que tratarnos de la forma adecuada", dijo un analista político iraní.
El Omid, lanzado cuando Irán celebra el trigésimo aniversario este mes de la revolución islámica de 1979 que derrocó al shah, que contaba con el respaldo de Estados Unidos, está diseñado para investigación y telecomunicaciones, dijo la televisión estatal. La cadena mostró imágenes de un cohete despegando de una plataforma de lanzamiento e iluminando el cielo nocturno.
"Querida nación iraní, vuestros hijos han colocado el primer satélite autóctono en órbita", dijo el presidente Mahmud Ahmadineyad en un mensaje televisado. "Con la ayuda de Dios y el deseo de justicia y paz, la presencia oficial de la República Islámica fue registrada en el espacio", declaró.
Construir el PAK-FA solo para ver quien la tiene mas grande como pareces indicar es solo una tontería y que permiteme decirte, la Federación Rusa no está para esos juegos desde que cayo la URSS.
Gripen NG Tender for Brazil
Gripen International
Today Saab handed over a tender for 36 Gripen Next Generation to the Brazilian Air Force Air Command. The tender is an answer to the formal Request for Proposal that was issued in the autumn 2008.
Gripen NG is the next generation Gripen, an enhanced version of the well established net centric warfare multirole fighter which has proven low acquisition, operation and support costs. The Gripen NG programme covers development of avionics and all major sensors including data communication, self-protection systems, weapons integration, as well as airframe and propulsion enhancements. The aircraft will have increased thrust, increased payload, and extended range.
“The Gripen NG offer is fully compliant and will be a complete solution for Brazil,” says Gripen Campaign Director for Brazil, Bengt Janér.
Generate transfer of key technology
Not only will Gripen NG provide an unbeatable industrial co-operation package, with lasting consequences for the national defence industry, such as the direct involvement in the development, production and maintenance of the platform but it will also generate transfer of key technology including access to Gripen source codes. These industrial packages will include contractually binding obligations.
The transfer of the Technology programme will also allow full involvement in future capability development supplying Brazil strategic long term national security and technology superiority.
A long term partnership
“Gripen NG will provide a long term partnership between Brazil and Sweden in a well established fighter programme that continues to develop. Gripen will maintain its position at the cutting edge of technology for the next 30-40 years”, says Saab CEO Mr. Åke Svensson.
Gripen is in service with the Swedish, Czech Republic, Hungarian and South African Air Forces. It has also been ordered by the Royal Thai Air Force. The UK Empire Test Pilots’ School (ETPS) is operating Gripen as its advanced fast jet platform for test pilots worldwide. Saab is also delivering successful industrial cooperation programs in Czech Republic, Hungary and South Africa.
US Navy Retires Last S-3B Viking From Fleet Service
Lockheed Martin
NAS JACKSONVILLE: The U.S. Navy retired the last Lockheed Martin S-3 Viking from fleet service in ceremonies here this morning, closing out the aircraft's distinguished 35-year Naval career.
Development of the S-3 began in August 1969, and first flight occurred on January 21, 1972. Sea Control Squadron 41 (VS-41), the S-3 training unit known as the Shamrocks and the first operational S-3 unit, received its first aircraft in February 1974. A total of 187 S-3s were built (eight test and 179 operational aircraft) between 1971 and 1978. Over its career, the Viking served with 18 Navy squadrons and accumulated approximately 1.7 million flight hours.
"The S-3 Viking was known as the 'Swiss Army Knife of Naval Aviation' and served the U.S. Navy well in a wide variety of roles over the course of its operational service life," said Ray Burick, Lockheed Martin vice president of P-3/S-3 programs. "The Viking has played a critical role in carrier-based anti-submarine and anti-surface warfare, as well as overland operations, refueling, targeting, and electronic surveillance. And of course Lockheed Martin is proud of the role it will continue to play in support of these critical Navy carrier-based missions, as many of these missions will eventually be carried out by the F-35C Lightning II."
The first S-3 was built at the then-Lockheed Aircraft Co. plant in Burbank, Calif., and was trucked to the company's facility in Palmdale, Calif., for first flight. Company pilots John Christiansen and Lyle Schaefer were at the controls, kicking off a 26-month test program. Among its notable firsts, the S-3 was the first antisubmarine warfare (ASW) platform to have a computerized acoustic system.
Sea Control Squadron 29 (VS-29), known as the Dragonfires, made the first S-3 deployment aboard the USS John F. Kennedy (CVN-67) in July 1975. The S-3 fleet surpassed 100,000 flight hours less than two years after that first deployment.
Several variants of the S-3 carried out a range of missions for the U.S. Navy. Seven aircraft were modified to US-3A Carrier Onboard Delivery aircraft, capable of carrying 4,250 lbs. of cargo. The ES-3A Shadow was designed for fleet electronic surveillance, replacing the EA-3B. Sixteen aircraft were modified to ES-3A configuration, and the first mission capable Shadow flew in May 1991. Development of a KS-3A tanker variant began in 1979; although the KS-3A was never produced, it did prove the concept of "buddy tanking" (aerial refueling using a wing-mounted pod), which most S-3s later performed. At the height of combat operations during Operation Iraqi Freedom, S-3 crews transferred nearly eight million pounds of fuel to Coalition aircraft.
The significantly improved S-3B was developed in the early 1980s to better detect quiet Soviet submarines, identify targets and carry standoff weapons. The S-3B flew for the first time in prototype form in September 1984. During Operation Iraqi Freedom, an S-3B from VS-38, the World Famous Red Griffins, carried out the first S-3 attack mission, disabling Saddam Hussein's ocean-going yacht with a laser-guided Maverick air-to-surface missile. In 2003, an S-3B from VS-35 became the first aircraft ever to have the Navy One call sign when it carried former President George W. Bush to the USS Abraham Lincoln (CVN-72).
Under the S-3 Integrated Maintenance Program (IMP), Lockheed Martin and Navy personnel worked side-by-side to perform scheduled depot maintenance and repairs on the S-3s to return the Vikings rapidly to the operational fleet. The program began in 2001, primarily as a means of reducing the backlog at Naval Aviation depots. IMP increased S-3 aircraft operational availability by 53 percent and reduced maintenance tasking by 47 percent over the depot-level maintenance plan. IMP also resulted in significantly reduced costs to the Navy. A total of 149 aircraft were processed through the IMP inspections, and nearly all of the aircraft were redelivered to the Navy on or ahead of schedule. The program concluded in 2007, as the Viking fleet was being drawn down.
"The S-3 Viking will long be remembered for its mission capability, its flexibility and its reliability," said Burick. "The aircraft has served the U.S. Navy admirably for more than three decades. We salute all who have flown and supported the Viking."
The NASA Glenn Research Center near Cleveland, Ohio, currently has four S-3B Vikings, performing aircraft icing research missions. It is likely that four S-3Bs will remain in Navy service, although in a support role providing range surveillance at the Naval Air Warfare Center Weapons Division at Point Mugu, Calif.
Headquartered in Bethesda, Md., Lockheed Martin is a global security company that employs about 146,000 people worldwide and is principally engaged in the research, design, development, manufacture, integration and sustainment of advanced technology systems, products and services. The corporation reported 2008 sales of $42.7 billion.
