General Dynamics Awarded $30 Million for Development of Advanced Submarine Technologies

Under the terms of the modification, Electric Boat will perform advanced submarine research and development studies in support of a wide range of technology areas including manufacturability, maintainability, survivability, hydrodynamics, acoustics and materials. Electric Boat also will conduct research and development work in affordability, manning, hull integrity, performance, ship control, logistics, weapons handling and safety. Additionally, the contract supports near-term Virginia-class technology insertion, future submarine concepts and core technologies.

A report filed by Michael Gilmore, chief of the Pentagon testing office, stated that the P-8A Poseidon exhibited flaws in the “plane’s radar performance, sensor integration and data transfer,” according to Bloomberg reporter Tony Capaccio, who received an early version of Gilmore’s report.

The U.S. Navy has spent about $35 billion on the P-8. The reported stated that the aircraft, which was built to replace the P-3 Orion, is not yet deployable, according to Gilmore’s report.

U.S. SUBMARINE FORCE VISION -  

The U.S. Submarine Force will remain the world's preeminent Submarine Force. We will aggressively incorporate new and innovative technologies to maintain dominance throughout the maritime battlespace. We will promote the multiple capabilities of submarines and develop tactics to support national objectives through battlespace preparation, sea control, supporting the land battle and strategic deterrence. We will fill the role of the Joint Commanders' stealthy, full spectrum expeditionary platform.

The Challenge

Nuclear powered attack submarines traditionally have been characterized by their superior blend of stealth, endurance, agility, and firepower. Endowed with these attributes, submarines play a key role in our warfighting and forward-presence strategy. As an example, SSNs comprise a surprisingly high percentage of the total Tomahawk capability in each U.S. Battle Group (about 20 percent) and launched approximately 25% of all Tomahawks during the Kosovo conflict1. Their capabilities as submarines were also critical to their ability to provide sustained presence and conduct critical surveillance prior to the conflict and to surge to the Adriatic Sea with other naval forces when hostilities commenced. Nevertheless, submarine design has traditionally placed limitations on submarine volume, which consequently limits submarine sensor and weapon payloads. Additionally, the dramatic explosion and proliferation of technology will make highly capable weapons systems affordable and easily accessible to potential adversaries that would not otherwise be able to pose a credible threat to U.S. forces. Increasingly, pursuit and implementation of rapidly changing warfighting capabilities will be essential to keeping up with emerging threats. Submarine innovation, including a long-term technological development and insertion program, promises to overcome these challenges and dramatically improve submarine capabilities in the 21st century.

USS Denver Departs For Deployment

SASEBO, Japan (NNS) -- Amphibious transport dock ship USS Denver (LPD 9), departed Sasebo, Japan for deployment in 7th Fleet Area of Responsibility Jan. 27.

Denver is the second oldest deployable ship in the U.S. Navy behind the USS Constitution.

"The oldest gator in the U.S. Navy, is what we call ourselves," said Operations Specialist 1st Class Jamie Dixon, assigned to USS Denver. "It's an older ship so we face different problems than other vessels in the fleet, but when it's time to get underway we are always up for the challenge."

During this deployment, Denver will participate in its Spring Patrol of 7th Fleet Area of Responsibility and the annual exercise, Cobra Gold, which is a joint venture between U.S. Navy and Thailand.

Les Tico devraient être remplacées par les Burke Flight III à partir de 2020. Cependant, le design des Burke III n'est pas encore totalement fixé; ça risque d'être un navire pas mal différent des Burkes actuels (plus long, plus lourd, avec une version un peu plus petite du AMDR, le super-radar prévu à l'origine pour le CGX) et éventuellement quelques VLS de plus. Est-ce que ce serait vraiment encore des Burkes ou ne faudrait ils pas les dégnigner croiseurs et leur donner un nouveau nom de classe? (Après tout, les Tico n'étaient que des Spruances allongées aussi)

Le concept du LCS est un échec. Pas asser armé dixit les officiels américains et trop cher pour des missions de police. Je pense que l'on verra dans quelques années un projet de corvette/frégate similaire au OH Perry. Pour les croiseurs Ticondegora, j'ai cru comprendre que parmi les mesures d'économie annoncé par le secrétaire a la défense il y a quelques semaines, une douzaine serait refondu pour durer quelques décennies supplémentaire.

Fiscal Year 2014 Navy Destroyer Contract Awards Announced

 

140309-N-IP531-162.JPG

WASHINGTON (NNS) -- Today, the Navy announced two separate contract awards for Fiscal Year (FY) 2014 destroyers.

The first contract award funds one FY 2014 DDG 51 Arleigh Burke Class destroyer under a previously awarded FY 2013-2017 multiyear procurement (MYP) contract with Huntington Ingalls Industries (HII). The second award is to exercise the option for one DDG 51 Class ship to General Dynamics Bath Iron Works (BIW) under a previously awarded FY 2013-2017 MYP contract.

General Dynamics Bath Iron Works (BIW) is being awarded a $642,583,946 modification to their existing fixed-price incentive firm target (FPIF) contract to exercise options for construction of a DDG 51 Class ship. The modification also provides $79,400,000 in advanced procurement funding for the FY 2016-2017 ships.

Huntington Ingalls Industries (HII) is being provided funding of $601,990,190 for the FY 2014 DDG 51 class ship and exercised options. The modification also provides $79,400,000 in advanced procurement funding for the FY 2016-2017 ships.

“We need to closely examine whether the LCS has the independent protection and fire power to operate and survive against a more advanced military adversary and emerging new technologies,” he said Feb.24.

Hagel has directed the Navy to provide these alternative proposals within a year.

“We must direct shipbuilding efforts toward ships that can operate in every region and along the full spectrum of conflict. At my direction the Navy will submit alternative proposals for a surface combatant consistent with the capabilities of a frigate. New ship designs and a modified LCS– proposal are due at this time next year to inform budget submissions,” Hagel said.

Referred to as a small surface combatant, the new platform or modified LCS is not yet known, a Navy official said.

The study is also looking at existing foreign variants of the LCS, some of which are larger and configured differently than U.S. versions.

“All of the things that are out there will be part of the market place of ideas,” a Navy official said.

L'US Navy devrait écouter le Sénat parfois... l'USCG sait faire construire des patrouilleurs et des côtres, et l'USN vient de montrer qu'elle n'y arrive pas, tout en s'entêtant dansuen voie qui demande trop de choses sans sen donner les moyens. Bref, à vouloir tout faire, on finit souvent par tout rater.

 

Ce qui est dommageable pour l'USN, c'est que le principe de réduction des équipages risque de passer à l'as en même temps que les LCS si l'échec est acté, alors même qu'ils ont encore de gros efforts à faire s'ils veulent réduire leurs coûts humains de leurs navires actuellement pléthoriques.
