ça fait plusieurs années qu'ils cherchent à acquérir 2 nouvelles corvettes mais il y'a rien de concret pour le moment , ce qui est certain c'est que les futurs corvettes seront armées de missiles barak 8 de 70 km de portée et ils auront aussi une capacité land attack .

revoie les pages de l'armée israélienne, on en déjà parlait, les israéliens vont acheté allemand !! en fait d'un coté technique, les corvette allemand dépasse largement les autres concurents !! et Israél va bénficier apparament d'un transfert de technologie !

Oui, un transfert de technologie, plus un transfert de l'argent du contribuable sous forme de remise sur le prix ou subvention de prix... pour indemniser les ''victimes'' du régime nazi.

l'offre de l'américain Gibbs & Cox lors du programme AWD de la marine australienne , une propostion basée sur une délainaison moins lourde des derniers Arleigh Burke Flight IIA , mais l'offre a été décliné en faveur d'un design espagnol dérivé de la frégate F 100 moins cher , moins risqué mais moins armé .

ça ressemble à la classe Atago japonaise, elle est aussi une déclinaison de la Arleigh Burke, et plus ou moins même tonnage.

oui tout à fait mais je dirais plutot un ATAGO downsized en version de +8000t , l'ATAGO est plus lourd et plus armé qui se rapproche plus du croiseur que du destroyer avec ses +10000t

Raytheon Receives $13 Million for Aegis Modernization

TEWKSBURY, Mass., Aug. 5, 2010 /PRNewswire/ -- Raytheon Company (NYSE: RTN) was awarded a $13.7 million U.S. Navy contract to upgrade the Aegis weapons system for several Arleigh Burke-class destroyers and Ticonderoga-class cruisers.

Under the Aegis modernization baseline contract, Raytheon will implement various ordnance alterations to enhance the weapons system's tracking performance and missile communication capabilities. The upgrades will improve radio frequency signal generation, allow missile data downlink for ballistic missile defense operations, and enable operation with current missile configurations.

"These upgrades will strengthen the capabilities of Aegis, improving the reliability and effectiveness of this frontline weapons system," said Raytheon Integrated Defense Systems' (IDS) John Kelly, director of Sensor Systems. "Raytheon continues its legacy of radar systems expertise, serving a critical role in the modernization of Aegis and helping the Navy to remain ahead of sea-based threats."

Raytheon's AN/SPY-1 radar transmitters and MK99 Fire Control Systems have been in production for 30 years as part of the U.S. Navy's Aegis shipbuilding program. In addition to supporting Ticonderoga-class cruisers and Arleigh Burke-class destroyers, the systems are also installed in Japan's Kongo-class destroyers and Spain's F100-class frigates. Raytheon's transmitter and fire control systems are vital to the Aegis weapon system's ability to track and defend against multiple threats, including aircraft and missiles.

This contract follows a recent $59.2 million award to Raytheon, under which the company will procure critical Aegis components for DDG 114 and DDG 115 – future Arleigh Burke-class destroyers.

Work on the Aegis program is performed at Raytheon IDS' Surveillance and Sensors Center, Sudbury, Mass., and at the Integrated Air Defense Center, Andover, Mass.

Second-Generation Aegis Ballistic Missile Defense System Completes Successful Intercept Flight Test


The Missile Defense Agency (MDA) and U.S. Navy sailors aboard the USS LAKE ERIE (CG 70) successfully conducted a flight test of the Aegis Ballistic Missile Defense (BMD) system, resulting in the first intercept of a short-range ballistic missile target over the Pacific Ocean by the Navy’s newest Missile Defense interceptor, the Standard Missile – 3 (SM-3) Block 1B.

At 8:18 p.m. Hawaiian Standard Time (2:18 a.m. EDT May 10) the target missile was launched from the Pacific Missile Range Facility, located on Kauai, Hawaii. The target flew on a northwesterly trajectory towards a broad ocean area of the Pacific Ocean. Following target launch, the USS LAKE ERIE detected and tracked the missile with its onboard AN/SPY-1 radar. The ship, equipped with the second-generation Aegis BMD 4.0.1 weapon system, developed a fire control solution and launched the Standard Missile-3 (SM-3) Block IB interceptor.

The USS LAKE ERIE continued to track the target and sent trajectory information to the SM-3 Block IB interceptor in-flight. The SM-3 maneuvered to a point in space, as designated by the fire control solution, and released its kinetic warhead. The kinetic warhead acquired the target, diverted into its path, and, using only the force of a direct impact, engaged and destroyed the threat in a hit-to-kill intercept.

Today’s event, designated Flight Test Standard Missile-16 (FTM-16) Event 2a, was the first successful live fire intercept test of the SM-3 Block IB interceptor and the second-generation Aegis BMD 4.0.1 weapon system. Previous successful intercepts were conducted with the Aegis BMD 3.6.1 weapon system and the SM-3 Block IA interceptor, which are currently operational on U.S. Navy ships deployed across the globe.

Aegis BMD 4.0.1 and the SM-3 Block IB interceptor improve the system’s ability to engage increasingly longer range and more sophisticated ballistic missiles that may be launched in larger raid sizes. The SM-3 Block IB interceptor features a two-color infrared seeker, which improves sensitivity for longer-range target acquisition and high-speed processing for target discrimination. The SM-3 Block IB interceptor also features an upgraded onboard signal processor and a more flexible throttleable divert and attitude control system to maneuver the IB interceptor to intercept.

Initial indications are that all components performed as designed. Program officials will conduct an extensive assessment and evaluation of system performance based upon telemetry and other data obtained during the test.

FTM-16 Event 2a is the 22nd successful intercept in 27 flight test attempts for the Aegis BMD program. Across all Ballistic Missile Defense System programs, this is the 53rd successful hit-to-kill intercept in 67 flight test attempts since 2001.

Aegis BMD is the sea-based midcourse component of the MDA's Ballistic Missile Defense System and is designed to intercept and destroy short to intermediate-range ballistic missile threats. The MDA and the U.S. Navy cooperatively manage the Aegis BMD Program.
