¡Leñe! Los americanos van a reinventar el Bhramos...

Bueno, la verdad es que la DARPA ya tenía desde hace unos añitos un programa de investigación en curso sobre un misil antinavio supersónico lanzable desde VL y desde vectores aéreos. RATTLR creo que lo llamaban.
Las imágenes infográficas que había del mismo erán muy similares a las de este LRASM, de manera que entiendo (aunque no se dice en ningún lado) que este es consecuencia de aquel. De un estudio teórico se pasa a un programa de demostración con sus prototipos y tal.

A ver que sale, pero huelga decir que a nosotros no nos viene mal que siga aumentando la variedad de municiones lanzables desde el MK-41...

Bueno, esta otra noticia añade algún dato adicional:
http://defense-update.com/features/2010/november/18112010_lrasm.html

en concreto:

Another design known as RATTLR (seen in the image above) was also studied by the US Navy in past years but has not matured into a full scale development program.

Es decir, las imágenes que se están mostrando asociadas a la noticia del LRASM son de hecho del fenecido proyecto RATTLR (ya me parecía que me sonaban ), de manera que aun no sabemos como pintará el nuevo misil, aunque es posible que no muy diferente....

Pocas fuerzas como la US-NAVY puede hacer tanta ostentación de poder, cuando los demás en el mundo estiran el prespuesto con sacrificios los chicos de las Barras y Estrellas trabajan horas extras para gastar el dinero de los contribuyentes, un ejemplo de esto fue el gasto de $450,000 dólares para que 4 F-18 en formación sobrevuelen el estadio de los vaqueros, lugar del Super Tazón, lo curioso es que nadie dentro del estadio los vió en vivo, ya que el estadio tiene un techo correrizo que al momento del evento estaba cerrado, los aficionados presente vieron el sobrevuelo por las pantallas gigantes al interior del estadio, siendo así los chicos de la navy pudieron haber hecho su vuelo en Virginia donde están basado y ahorrar algunos verdes, o mejor aún usar algunas tomas de archivo.

But Mike Maus, deputy public affairs officer for the Naval Air Force’s Atlantic division, told CNBC that he isn't aware of the specific tables that Harris obtained. He says that the only cost of the trip that the Navy records is the fuel cost, which was $109,000.

Maus also said he thought the press was mischaracterizing some aspects of the flyover.

“These missions are included in the annual operating budget of all branches of the military and they are used as training,” Maus said. “There was no additional money provided to us, Congress did not cut us a special check to do this flyover. This is considered a training mission whether they were to fly over the Super Bowl or not.”

Maus said the flyovers actually provide pilots with essential training needed for missions including instrumentation and communication practice.

Maus also said that the money is well spent because it helps the military recruit.

“I can’t put a specific dollar attributed to what we did on Sunday, but we know we gained some recruiting points,” Maus said.

La cosa entonces cambia un poco de la noticia original, que resulta ser un tanto sensacionalista.

EA-18G Growler deployed for the first time by the U.S. Navy.

ST. LOUIS, Feb. 17, 2011 -- Boeing today announced that EA-18G Growler airborne electronic attack aircraft have been deployed for the first time by the U.S. Navy.

"The men and women of Boeing are honored to see this new capability directly benefit the nation’s brave servicemembers around the world," said Kory Mathews, vice president of F/A-18 and EA-18 Programs for Boeing. "The airborne electronic attack capability that the EA-18G brings to the fight is in high demand, so we are committed to continuing to deliver these aircraft to the Navy on budget and on schedule, just as we have with every F/A-18E/F."

The EA-18G is the only air combat platform that delivers full-spectrum airborne electronic attack (AEA) capability along with the targeting and self-defense capabilities derived from the Navy's frontline fighter, the F/A-18E/F Block II Super Hornet. A derivative of the two-seat F/A-18F Block II, the EA-18G's highly flexible design enables warfighters to operate either from the deck of an aircraft carrier or from land-based airfields. It is replacing the Navy's current AEA platform, the EA-6B Prowler, which has been in service since 1971. The EA-18G joined the Navy's aircraft fleet in 2008, when it was introduced to fleet training squadron VAQ-129.

Boeing, acting as the weapon system integrator and prime contractor, leads the EA-18G Growler industry team, which also includes Northrop Grumman, Raytheon and General Electric Aircraft Engines.

Jó, este acrónimo si que se las tráe: Revolutionary Approach To Time Critical Long Range Strike (RATTLRS)

Si no ando errado, el Brahmos tiene una autonomía de unos ~300 Km, pero el RATTLRS, al parecer, y según he podido averiguar en Global Security, sería un calibre algo más gordo.

* Increased cruise speed (Mach > 4.0, ~4,000 km/hr)
* Increased acceleration (> .5g)
* Longer cruise time (> 15 minutes), implying a range up to 1,000 km.
* Optimized vehicle configuration for payload, range, or endurance
* Improved efficiency in multiple speed regimes.
* Reduced cost
* Multiple-launch platform capable

Lo del "reduced cost", para quien se lo quiera creér .

A ver como evoluciona el tema.

Antiship Missiles Threaten Status Quo

The debate over China’s new DF-21D antiship ballistic missile and the impact it could have on sea power in the region is reviving concerns over the threat antiship missiles pose—a threat that had faded with the end of the Cold War.
Since the fall of the Soviet Union, Western naval strategists have seen little need to continue developing ship-killing missiles. The trend has been to retrofit weapons in service with advanced features. With few instances of antiship missiles being used against naval targets, many commands viewed the threat as remote. Several prominent projects were canceled as a result, including the French Future Antiship Missile program and Italy’s Ulisse long-range missile. This also explains the longevity of the Boeing Harpoon and MBDA’s Exocet, which have added capabilities to existing designs, and the U.S. Navy’s decision to retire the antiship version of Raytheon’s Tomahawk cruise missile.
But the situation is changing, especially in the Asia-Pacific region, where China, India and South Korea are building blue-water navies that will include carrier battle groups. Another concern is the proliferation of advanced antiship missiles, mainly of Russian origin, which are raising doubts about the effectiveness of Western ship defenses.
The DF-21D is actually of less concern—at least for now—than a salvo of Russian-made Club cruise missiles. A massed attack of antiship missiles would give a defender tens of seconds to react when detected on radar, compared with 12 min. for a ballistic missile. This is due to their low sea-skimming attack profile—as little as 2 meters (6.5 ft.) above the waves—and supersonic or high subsonic speed.
Antiship missiles are becoming more dangerous. Many feature advanced radar and infrared (IR) stealth designs, such as Kongsberg’s NSM and Saab’s evolved RBS-15. Modern missiles are wired for “smart” flight with, among other features, improved electronic counter-countermeasure capabilities. Weapons such as the latest Exocet Block 3 from MBDA fly elaborate attack profiles, pulling high g-forces and 3D maneuvers to defeat defensive systems. Other missiles dive at supersonic speed or, like the Club, fly meters above the waves at Mach 2. Supersonic weapons, moreover, don’t need heavy warheads due to the kinetic energy they develop and the incendiary effect of residual fuel.
Modern antiship missiles can be launched from ships, aircraft, coastal batteries or submarines. In some cases a single weapon type is used for all these platforms—for example, the Harpoon or Russian Kh-35 Uran.
As a result of renewed concerns about these weapons and fears that some navies could be outgunned in a confrontation, a number of missiles are under development or being radically upgraded.
There is a business as well as a strategic benefit to having an exportable, modern weapon: The Harpoon has been sold to 30 countries and produced in around 7,300 units, reducing cost.
Following termination of the Harpoon Block 3 program, which would have added a Rockwell Collins data link and improved attack features to the Boeing missile, the Block 2 is the sole heavy weapon in the U.S. antiship missile arsenal. Weighing 690 kg (1,518 lb.) and carrying a 220-kg warhead, Harpoon is turbojet-powered and has a range of 80 nm. It will likely evolve until a replacement comes from the many research programs dealing with high-speed strike missiles or other initiatives, such as the Long Range Anti-Ship Missile project initiated by the U.S. Defense Advanced Research Projects Agency. In this effort, Lockheed Martin is working on an extended-range Joint Air-to-Surface Standoff Missile (Jassm) derivative and a ramjet-powered supersonic missile (see p. 33), which are to fly in demonstrator form in 2013.
In Europe, MBDA’s Exocet MM40 Block 3 is the latest evolution of the Exocet, which dates to the 1970s. The main innovation is replacement of the rocket sustainer engine with a Microturbo TRI-40 turbojet, which solves the issue of the Block 2’s relatively short range. The Block 3 flies more than 100 nm. and benefits from new features such as advanced electronics and a corkscrew attack profile. The electronics are being retrofitted to the Block 2 air-launched AM39 Mod 2 and sub-launched ASM39 Block 2. Mod 2 Exocets carry 160-kg warheads and reach high subsonic speeds. They are in service with 35 countries and have been produced in more than 3,500 units. The Exocet is also an extensively used weapon, with at least 700 fired in action, many in the air-launched variant. MBDA is evaluating further improvements, including a new radar seeker and a data link.
MBDA also offers the Otomat Mk2 Block IV, which has an inertial navigation system (INS) and GPS for intermediate cruise flight, an active seeker and a radio link that allows the missile to be controlled during flight from a ship or helicopter. It has a range of more than 100 nm., weighs 770 kg and is fitted with a semi-armor-piercing 210-kg warhead.
MBDA contributed to the development of Kongsberg’s NSM, which uses the Exocet Block 3 engine. The NSM, which replaces the Penguin missile, has an imaging IR sensor for terminal guidance. The attack radar sensor opens up at ranges beyond 30 mi. An inertial and satellite navigation system is used for the mid-course phase and eventually combines with a data link or radio command. A highly accurate radar or laser altimeter is another standard feature. NSM is light—and so a candidate for helicopter launch—but delivers a heavy punch with a 120-kg warhead at a range exceeding 100 nm.
Saab and Diehl are producing the RBS-15 Mk3 missile, in use by the Swedish, German and Polish navies. With a range of more than 120 nm., the Mk3 is the latest variant of a family of missiles introduced in the 1980s. It weighs 630 kg, flies a sea-skimming profile, maneuvers at more than 8g during final attack and has a warhead of at least 250 kg.
Four companies have taken the lead in development of Russian antiship missiles—Zvezda, Novator, NPO Mashinostroyenia and Raduga.
The Zvezda-Strela Kh-35 Uran (known in the West as the SS-N-25 Switchblade) is jet-powered, weighs 600 kg, has a 143-kg warhead, 70-nm. range (a newer Uranium version doubles the range) and high subsonic speed. It conducts final attack 3-5 meters above the water.
Novator’s Club family includes specialized missiles launched from torpedo tubes and vertical launch systems, making it a popular international weapon. The antiship versions of the SS-N-27 Sizzler are the 3M-54E1 cruise missile, with 160-nm. range and high subsonic speed; and the 3M-54E, which includes a terminal rocket-powered stage that accelerates to Mach 2.9. Each weighs 2 tons, is 9 meters long and carries different warheads. The subsonic version has a 400-kg warhead and 150-nm. range, and the supersonic missile has a 200-kg warhead and 120-nm. range.
NPO’s Moskit (SS-N-22 Sunburn), at 4.2 tons and 9.2 meters long, is a ramjet-powered missile that flies at high altitude at Mach 3, or at a 7-20-meter sea-skimming profile at Mach 2.2. It has a range of 50-120 nm., and carries a 300-kg warhead.
The NPO P-800 Yakhont (SS-N-26 Sapless) is 3 tons, 9.75 meters long, ramjet-powered and reaches Mach 2.8. It can adopt a low-high-low profile, with a cruise altitude of 14,000 meters and final attack profile of 10-15 meters. High-altitude flight yields a 170-nm. range; at low altitude, range is less than 70 nm. The Yakhont has a 250-kg semi-piercing warhead and pulls 20g. It is the basis for the Indian-Russian BrahMos, now entering service.
China’s Cheta missiles are not advanced (the People’s Liberation Army Navy relies to a large extent on Russian missiles). The older C-601/611 missiles of Styx heritage are obsolete. But the newer C-801/802A missiles are 800-kg weapons, turbojet-powered, with 190-kg warheads, 100-nm. range, and loaded with INS and active radar guidance. The C-602 cruise missile is 1,350 kg, carries a 300-kg warhead and has a range of 160 nm. The C-705 cruise missile is 325 kg, has a 130-kg warhead and 80-nm. range.
None of these weapons compares with the best that Russian and Western companies are developing or deploy, but they are cheap and can be sold to countries that have no access to anything better.
Other countries have developed indigenous designs, such as Israel’s IMI Delilah SL, a turbojet missile with a range of more than 140 nm., for ground and air launch.
Taiwan has the Mach 2 HF-3, which has a range of 300 km.
South Korea’s Lig Nex1 C-Star is a turbojet missile with a range exceeding 80 nm.

¿Que os parece el rumor de que a los nuevos clase Virginia se les va a añadir una seccion de 90 pies para llevar 194 Tommys?

Al parecer sustituirian a los 4 Ohio reconvertidos cuando estos se retiren alla por los 2020s, lo que conllevaria perder el 60% de la potencia de fuego convencional del arma submarina si no se reemplazan con algo igual de capaz.

¿Asisitiriamos pues al nacimiento de un nuevo tipo de submarino? El primer "Fast attack cruise missile submarine"... algo que tiene mucho sentido sabiendo la alergia de la Navy a perder potencia de fuego en cualquier arma y mas en la submarina, por las obvias capacidades añadidas destacando la de la discreccion.

¿Alguna opinion?
