Misiles y armas aire-aire, aire-superficie y antiaéreos

Pues al hilo de lo que comentais, un artí­culo sobre la conveniencia de fusionar los datos de los AEGIS con otros sensores, especialmente el F-35 (y especialmente en Asia, que los de aquí­ cada vez pintamos menos). De este modo un AEGIS podrí­a disparar un misil señalado por un F-35 y viceversa: http://www.usni.org/magazines/proceedin ... each-aegis

...
Upcoming tests will support a launch/engage-on-remote concept that links the Aegis ship to remote sensor data, increasing the coverage area and responsiveness. Once this capability is fully developed, SM-3 missiles''''no longer constrained by the range of Aegis radar to detect an incoming missile''''can be launched sooner and therefore fly farther to defeat the threat.

Imagine this capability linked to an F-35, which can see more than 800 miles throughout a 360-degree approach. U.S. allies are excited about the linkage prospects and the joint evolution of two highly upgradable weapon systems. Combining Aegis with the F-35 means joining their sensors for wide-area coverage. Because of a new generation of weapons on the F-35 and the ability to operate a broad wolfpack of air and sea capabilities, the Joint Strike Fighter can perform as the directing point for combat action. Together, the F-35 and Aegis greatly expand the defense of land and sea bases.

The commonality across the combat systems of the F-35's three variants provides a notable advantage. Aegis is a pilot's wingman, whether he or she is flying an F-35A, B, or C. Eighty percent of the F-35s in the Pacific are likely to be As, many of them coalition aircraft. Therefore, building an F-35 and Aegis global enterprise provides coverage across the Pacific.

Many of our partners are already in the Aegis-deployed fleet, and several allies are prospectively interested in the joint Aegis/F-35. So as the F-35 Joint Strike Fighter comes on line, integrating Aegis with it also provides a powerful capability for our allies.

Combining the F-35B and Aegis opens up a whole new ability to defend land-based air in the Pacific. No longer should the B be considered a boutique niche aircraft essential only for Marine combat concepts of operations. With vision and commitment on numbers, it can become a tactical aircraft that sends a strategic signal. This is because the aircraft can stand strip alert on any long runway, whether U.S. or allied. From a strategic standpoint, this could include Guam, South Korea, or the Middle East.

As a crisis situation develops, the F-35Bs can be remotely placed in hardened bunkers and revetments, thus becoming a deterrence asset that can sortie instantly into combat, return to refuel, and go again—and again. With the use of an F-35B detachment, the issues of enemy runway area denial and rapid runway repair do not become show stoppers for the tempo of operations, both offensively and defensively.

Tie an F-35B to Aegis, and the entire “wasting argument”about asymmetric intermediate-range ballistic missiles and enemy strikes against our hard fixed land targets becomes moot. Guam, for example, will still have air power in its defense. The same principle can be applied globally.

16:52 GMT, January 24, 2012 TUCSON, Ariz. |
The U.S. Navy completed developmental and operational testing (DT/OT) of the newest variant of the Raytheon Company laser-guided Maverick missile. This brings U.S. Sailors and Marines one step closer to conducting airborne precision engagements of rapidly moving targets in urban environments.

"In numerous conflicts, Maverick has proven its effectiveness against ships, tanks, fast moving vehicles and fortified personnel," said Harry Schulte, vice president of Raytheon Missile Systems' Air Warfare Systems product line. "With the completion of DT/OT, Raytheon can begin producing and delivering this highly accurate weapon to the U.S. and coalition warfighter."

During four DT/OT tests, Navy and Marine Corps aviators fired four AGM-65E2 laser-guided Maverick missiles at moving and stationary targets from F/A-18C/D Hornets, F/A-18E/F Super Hornets and AV-8B Harriers. During one particularly challenging test, an AGM-65E2 was fired from a Harrier and accurately guided to a rapidly moving target via the laser designator of an AH-1Z Viper helicopter.

About the Maverick Family of Missiles
The laser-guided Maverick missile is a direct-attack, air-to-ground precision munition used extensively by the U.S. Air Force, Navy and Marine Corps in ongoing combat operations. The AGM-65E2/L has an enhanced laser seeker and new software that reduces the risk of collateral damage.

• Maverick is integrated on 25 aircraft and in the inventory of 33 nations.
• The AGM-65E2/L can use onboard, buddy and ground-based lasing to designate targets.

Ralentización en la entrega de AMRAAMs debido a problemas en el motor: http://www.defensenews.com/article/2012 ... |FRONTPAGE

Feb. 14, 2012 - 05:31PM |
By Dave Majumdar

The Pentagon has slowed down its purchases of the new AIM-120D version of the Advanced Medium Range Air-to-Air Missile (AMRAAM) because of problems with producing its rocket motors, the U.S. Air Force's top acquisition official said.

“They're behind on the delivery of the missile,”David Van Buren said Feb. 14 of the Raytheon-produced system. “There are problems with the motor.”

Van Buren was speaking to reporters after his speech at a defense conference in Arlington, Va. The Air Force has reduced the number of missiles it is buying to 113 units, down from 138 the year before. Overall, the Pentagon plans to spend $423 million on continued production of the active radar-guided AIM-120D for a total of 180 missiles, including Navy and Marine Corps buys.

Van Buren said the quality of the missiles that have been delivered is “fine,”but the weapons can't be produced in quantity due to a high rejection rate for the rocket motors being built.

“I wouldn't characterize it as a defect, I would characterize it as a through-put issue,”he said. “The through-put of acceptable motors is not meeting production schedules.”

But the Pentagon must have the new AMRAAM variant.

“The AMRAAM is a critical part of the air-to-air mission,”Van Buren said.

The next-generation Joint Dual-Role Air Dominance Missile, which would have replaced both the AMRAAM and the AGM-88 High Speed Anti-Radiation missile, which is used to suppress enemy air defenses, has been terminated because it was unaffordable.

Parece que el AAM-4B japonés tendrá AESA: http://www.aviationweek.com/aw/generic/ ... annel=awst

By Bradley Perrett

Japan already has bought Raytheon AIM-120 Amraams, so why is it spending ¥36 billion ($468 million) to upgrade about 60 F-2 fighters with the Mitsubishi Electric Corp. AAM-4B missile?

Although the benefits to Japanese industry are obvious, details of the upgrade and the missile itself suggest that the program is giving an enormous boost to the Mitsubishi Heavy Industries fighter's ability to counter enemy aircraft. The weapon has at least one advanced feature that other such missiles lack: a seeker with an active, electronically scanned array (AESA) radar.

The program will move into high gear in the financial year that begins April 1. The work is progressing in two parallel programs: integration of the AAM-4B missile, and upgrade of the J/APG-1 radar to a more powerful standard called J/APG-2. The improved radar, needed to exploit the new missile, will incidentally raise the capabilities of the aircraft by offering greater detection ranges.

Both systems have been developed by the Japanese defense ministry's Technical Research and Development Institute with considerable help from contractors, Mitsubishi Heavy Industries for the missile integration and Mitsubishi Electric for the radar. The same companies are contracted to do the installation work. Ministry officials tell Aviation Week that development went smoothly and is now complete.

Early in the development program, in 2001, the ministry gave rough indications of the AAM-4B's capabilities. It could be launched at a 20% greater range than could the then-current AAM-4 and at least as far as an “AIM-120B+,”a standard that was expected to appear around 2004. The crucial claim was that the AAM-4B could switch to autonomous guidance at a 40% greater range than either of the other two missiles and would similarly outperform what was expected to be the 2009 standard of the Russian R-77 (AA-12 Adder). In a 2010 paper, the ministry attributed the seeker's greater performance to the higher transmitting power available from the AESA.

The implication is that an F-2 firing AAM-4Bs can stop tracking the target for missile guidance much sooner than an unmodified F-2 can—and officials tell Aviation Week that the key aim of the project is indeed to increase the range at which an F-2 can turn away.

Referring to this detail, a former high-ranking U.S. Air Force officer says: “In the air-to-air realm, a 40% increase in range is very significant and would provide the [Japan Air Self-Defense Force] a very capable missile.”The same person, highly familiar with the electronic technology of air warfare, does not regard the advances claimed for the upgraded F-2 as improbable; they are to be expected, he says.

The ministry also says that the AESA seeker will have a better capability against a crossing target—one that reflects a radio signal with the same frequency as the ground. Fighter pilots can dive and turn at right angles to a threat to create that complication for enemy radars and missiles.

The number of F-2s that are already able to use the AAM-4B is undisclosed, but a budget allocation to do most of the radar upgrades in fiscal 2012 shows that the bulk of the installation program is only now getting underway. The missile integration, centered on an upgrade of the fire-control system, will be applied to 16 aircraft in that fiscal year, at a cost of ¥340 million per aircraft, while 40 will get the new radar, for ¥260 million each. Future budgets will determine when the planned 60 upgrades, enough to equip three squadrons, are completed. The work is being done in conjunction with heavy maintenance on each fighter.

Research and development of the F-2's fire-control upgrade began in 2004. The installation was mentioned in the fiscal 2010 budget, but little has been known about it. The ministry is always secretive about its air-to-air missiles.

Claro, ahí­ está la gracia. Ataca totalmente vertical, en la zona más desprotegida. Es una carga proyectada (y como es un carro cargado "realmente" revienta lo que lleva dentro (proyectiles, combustible...). Que te digan más los expertos.

Si no me equivoco, la variante F lanza un penetrador conformado. Entiendo la primera explosión, pero la segunda en la que el pobre T-72 se desintegra me parece un poco exagerada. No digo que hayan colocado algo de explosivo internamente para aumentarla, pero...

Hombre, podemos ser bien pensados y asumir que el penetrador autoformado ha zumbado precisamente en la parte del carrousel donde van las cargas de propelente de cada disparo de 125 y que estaba petado de munición.

Los acuerdos franco-ingleses de colaboración en materia de Defensa se centran especialmente en 3 ramas: en cuanto a la operativa es la colaboración entre sus portaaviones y aviación embarcada. Y en cuanto a la industrial, es el desarrollo conjunto de UAS, especialmente un MALE y el desarrollo de varias armas AS de precisión (esto menos conocido).
Entre estas armas se encuentran los siguientes proyectos:

- Misil de crucero con capacidad aire-tierra y antibuque. Podrí­a ser reemplazo del SCalp/storm Shadow y del Exocet sobre 2030.

- Concepto Perseus, misil con un motor de ¿onda de detonación contí­nua? (continuous-detonation-wave engine) para dar gran velocidad con mayor alcance. El desarrollo serio no comenzarí­a hasta después de 2020.

- En el futuro cercano, el Future Anti-Ship Guided Weapon (Heavy) ó FASGW(H) (ANL en francés). El contato para su desarrollo se darí­a en este año. De 110 kg de peso, es un misil antibuque para helos como el NH-90, el Panther y el Wildcat.

- Mejora del Scalp/Storm Shadow, eliminando obsolescencia y, notablemente, incluyéndole un enlace de datos de doble ví­a (misil-caza, caza-misil).

- A medio plazo, el Future Anti-Surface Tactical Missil, cuyos estudios iniciales acabarán este año. Es un misil ligero de 50 kg de peso anti-blindados, equivalente al MMP (medium-range weapon program) francés que pretende reemplazar sus Milan, que también está ya en estudio.

En Aviation Week también hablan de mejoras para los Storm Shadow e incluso para los Taurus:







Italia al parecer disparó varios sobre Libia con un acierto del 100%, pero quiere mejoras en sensores y en integrar mayor variedad de sistemas para la planificación de la misión. Digamos que quieren una resolución adecuada para mejorar los algoritmos del sistema de reconocimiento automático de objetivos. También quieren un data-link que envíe la última imagen del objetivo antes de ser atacado, y junto con los franceses (británicos no) también muestran por un data-link de dos direcciones que les permita cambiar de objetivo en vuelo. Por su parte, los británicos desean mayor alcance utilizando un combustible más energético.

Respecto al Taurus, se podría firmar un contrato de mejora este mismo año. El área de interés, es también un data-link que permita tanto mandar la última imagen del objetivo como reasignarlo (también útil para atacar buques al poder actualizar las coordenadas). Pero además se siguen estudiando variantes navales, terrestres e incluso la adaptada para lanzamiento desde transportes aéreos.

Francia también quiere aumentar la precisión del SCALP-NG dotándolo de doble data-link y receptores del sistema Galileo. Las primeras unidades se espera que lleguen en 2.014. En total, 200 (150 para las Fremm y 50 para los Barracuda). Y de nuevo doble data-link también en estudio para las AASM...

¿No se decía que el Galileo no tendría uso militar?
