The Navy’s current estimate is $3.3 billion for each lead ship while follow ship costs are projected to be significantly less. Based on the current build profile, the cost estimate for the fifth ship is $2.3 billion (FY11 dollars). Congress, in the FY06 Authorization Act, set a cost cap of $2.3 billion on the fifth ship in the DDG 1000 class.

Discussions about ship costs must also consider the changing value of money over time. For example, the lead DDG 51 Arleigh Burke was purchased in 1985 for $1.2 billion, but accounting for realistic inflation in the industries that make up shipbuilding, that ship would cost $2.4 billion today. With significant improvements across the board, $3.3 billion for each lead DDG 1000 versus the $2.4 billion (FY07 $) lead DDG 51 is a good value.

US$ 2,4 a 3,3 BILHÕES por navio...

Aí usa-se um U-214 de US$ 400 milhões com um torpedo de US$ 1 milhão para mandar um destes para o fundo do mar... Afinal, navegando próximo ao litoral, um destróier deste estará no "reino" do U-214... Imaginem o custo benefício para o atacante (e o prejuízo para o atacado)...

bem nessa... neste domingo ultimo, esteve em Itajai a F-42 modernizada e operacional... estive conversando com um tenente, e ele me falou o seguinte:
"...contra um submarino meu amigo, só outro submarino, falam que precisa-se de 7 escoltas modernas para detectar um sub, isso é balela, no minimo umas 15 e olha lá..."

PS: ele passou que os Bofors já estão integrados e cabeados, pelo menos na Constituição...

Também acho. Por isso digo que a forma mais eficaz da MB se tornar uma marinha muito potente é investindo em submarinos mesmo.

Poderiamos ter uma força tarefa moderna e bem treinada e dezenas de submarinos entre SSk´s e SNA´s.

Submarinos nacionais, torpedos pesados nacionais e sistemas nacionais....o resto pode variar.

Raytheon Successfully Integrates Final Element of Dual Band Radar for DDG 1000 Zumwalt Class Destroyer



(Source: Raytheon Company; issued Oct. 24, 2006)



TEWKSBURY, Mass. --- Raytheon Company has successfully integrated the engineering development model, S-Band array with receiver, exciter and signal/data processing equipment for the Volume Search Radar (VSR) portion of the DDG 1000 destroyer's Dual Band Radar (DBR).

The company is developing DBR for the next-generation Zumwalt Class destroyer. The VSR equipment was successfully operated with the S-band array and Beam Steering Controller software provided by Raytheon subcontractor Lockheed Martin.

"The Dual Band Radar is a critical asset to the DDG 1000 mission and the safety of our sailors," said Captain James Syring, the U.S. Navy's program manager for DDG 1000. "The radar project's schedule has been challenging, but achieving this critical milestone tangibly demonstrates the substantial progress being made on the program."

"The fact that this critical step was successfully completed on schedule can be attributed to the teamwork between the Navy and industry, as well as team dedication," said Ed Geisler, Raytheon vice president and DDG 1000 program manager, responsible for all DBR activity. "This teamwork has been a hallmark of the DDG 1000 program since its beginning."

The DBR is an active, phased-array, multi-function radar system, which incorporates X- and S-band arrays in a complementary manner to provide surveillance, target tracking and engagement support capabilities superior to those of conventional single-band radars.

The successful integration of the S-band array demonstrates progress toward the operation of a fully integrated Volume Search Radar, which is the final component of the DBR. Previously, Raytheon had successfully developed and tested the X-band component of the DBR, known as the AN/SPY-3, and recently proved its performance in extensive at-sea testing.

Under Raytheon's leadership, the DBR integration of both the SPY-3 and VSR components has advanced on schedule, and the recently completed milestones bring the advanced DBR closer to deployment on the Zumwalt Class destroyers, the CVN-78 next generation aircraft carrier and other future U.S. Navy ships.

Under the Navy's DDG 1000 Detail Design and Integration contract awarded in 2005, Raytheon IDS serves as the prime mission systems equipment integrator for all electronic and combat systems for the DDG 1000 Zumwalt Class Destroyer program.


Based in Tewksbury, Mass., Integrated Defense Systems is Raytheon's leader in Joint Battlespace Integration providing affordable, integrated solutions to a strong international and domestic customer base, including the U.S. Missile Defense Agency and the U.S. Armed Forces and the Department of Homeland Security.

Raytheon Company, with 2005 sales of $21.9 billion, is an industry leader in defense and government electronics, space, information technology, technical services, and business and special mission aircraft. With headquarters in Waltham, Mass., Raytheon employs 80,000 people worldwide.
