Toda vez que vejo esses projetos espalhafatosos dos EUA eu lembro da Lady Gaga cantando no superbowl.

Algo sem necessidade, mas que fazem mais por egocentrismo e quererem aparecer.

Thornberry cites my story yesterday in Defense News about 53% of Navy aircraft can't fly, 62% of strike fighters are down. Amazing numbers



Vice CNO Moran - Navy is running out of money, will have to shut down aircraft, ships. Service's shipyards can't handle the load

Quando ele entrou em operação, em 25 de novembro de 1961, o CVN-65 mudou o rumo da guerra aeronaval no mundo a partir de então. Seu comprimento era maior que do famoso dirigível rígido alemão dos anos 30, o LZ 129 Hindenburg, e maior ainda que o couraçado da antiga Marinha Imperial japonesa, o Yamato.

Com uma tripulação média de 3.000 marinheiros e oficiais, além de outros 1.800 militares destinados a voar e manter pouco mais de 60 aeronaves e as operações aéreas, o USS Enterprise foi o primeiro porta-aviões do mundo e o maior já construído até então. Tinha 342m de comprimento e peso superior a 94 mil toneladas.

Mas em 3 de fevereiro passado, o CVN 65 foi descomissionado após quase 55 anos de operação. Participou da Crise dos Mísseis de Cuba em 1962, de diversos deslocamentos para o apoiar as operações durante a Guerra do Vietnã – onde sofreu uma severa avaria após o grande incêndio causado por um disparo acidental de um foguete de 130mm que destruiu completamente 15 aviões e matou 27 pessoas de deixou outras 374 feridas -, além de diversas operações e ações pontuais na África, Oriente Médio e Ásia.

Ao longo de mais de cinco décadas quase 1,9 milhões de quilômetros foram percorridos graças aos oito reatores nucleares e as quatro turbinas a vapor que proporcionavam 280 mil cavalos de potência. Com uma carga nuclear o navio podia navegar por 25 anos. Ao todo foram feitas três dessas cargas.


Os danos no navio após o acionamento acidental e involuntário de um foguete Zuni, de 130mm, que estava carregado num McDonnell Douglas F-4 Phantom.

Big E é apelido herdado do CV-6 que foi lançado em 1936 e atuou na 2ª Guerra Mundial com o nome USS Enterprise (o CNV 65 é o sétimo navio da Marinha norte-americana com esse nome). Para os amantes de Top Gun, o CVN 65 foi o porta-aviões protagonista daquele sucesso dos anos 80 do cinema norte-americano com Maverick, Goose e Iceman!

The Highly Capable, Truly Scalable Radar

The Air and Missile Defense Radar – AN/SPY-6(V) – is the Navy's next generation integrated air and missile defense radar. It is advancing through development and on track for the DDG-51 Flight III destroyer.

The radar significantly enhances the ships’ ability to detect air and surface targets as well as the ever-proliferating ballistic missile threats.

SAS 2017: Austal Unveils Updated LCS Frigate Design with 16x Anti-Ship Missiles

At the Navy League’s Sea-Air-Space 2017 exposition currently held near Washington D.C., Austal USA rolled out an updated LCS Frigate design called the "Austal Frigate". The main modifications consist in a slightly shortened flight deck in order to fit anti-ship missile launchers and a variable depth sonar in order to add capabilities to the ship's aft.



According to Austal USA, the Austal Frigate possesses increased lethality and high-speed shallow draft multi-mission combatant capabilities on a seaframe nearly identical to the Independence-class Littoral Combat Ship. This ship's ability to meet and exceed current US Navy requirements makes it one of the most cost-effective, maneuverable and flexible ships in the fleet.



hanks to the extra space at the stern, there are now 8x over the horizon (OTH) anti-ship missiles in additition to the 8x launchers fitted forward, for a total of 16x anti-ship missiles. An Austal representative explained to Navy Recognition that the increased number of missiles exceeds the minimum requirement expressed by the US Navy, but is in line with the distributed lethality concept and doesn't need additional development.

The new stern space is also fitted with a variable depth sonar and its handling system as well as a towed array.


From left to right: 8x OTH missiles, CEROS 200 fire control radar, 3D radar, Mk41 VLS, NULKA decoy launchers, MSI Defence 30mm RWS, SEWIP antenna, SeaRAM

The new Austal Frigate design features optional Mk41 VLS (16 cells) in addition to the SeaRAM launcher.

Austal insists on the fact that the seaframe from the maindeck down is virtually identical to the existing LCS design and retains its qualities in terms of performance and affordability.



Austal Frigate specifications:
Length: 419 ft
Beam: 104 ft
Draft: 15 ft
Full load displacement: Approx. 3,500 Tons
Speed: More than 32 knots
Range: More than 4,300 nm @ 12 kts
Berthing: 130
Mission bay size: 7,000 square ft
Watercraft operations: 2x 7 meters RHIBS. Launch and recovery up to sea state 3
Flight operations: 1x H-60, up to sea state 5
Hangar:1x H-60 and 1x MQ-8C
Sensors: 3D search radar, 2x navigation radars, EO/IR fire control optics, variable depth sonar, multi-function towed array, electronic surveillance
Processing systems: COMBATSS 21 CMS, AN/SQQ-89 undersea warfare system, integrated bridge control system, automated machinery and damage control systems
Armament: SeaRAM, Mk110 57mm gun, 6x .50 cal guns, NULKA, 16x OTH missiles, 2x 25/30mm cannons, Helllfire AGM-114 missiles, torpedo countermeasures, 2x Mk41 launchers
Propulsion: 2x GE LM2500 gas turbines, 2x MTU 20V8000 diesel engines, 4x Wartsila steerabe, reversing waterjets.

HII's LPD-Based Future Surface Combatant Concept Could Replace Ticonderoga-class Cruisers

During the Navy League's Sea-Air-Space 2017 exposition held recently near Washington D.C., Huntington Ingalls Industries (HII) was showcasing its "Future Surface Combatant" based on a LPD-17 / San Antonio-class hull form.


HII's Future Surface Combatant at Sea Air Space 2017.

According to an HII representative, the scale model is representative of what a future surface combatant could look like based on future fleet architecture studies by the US Navy and various think tanks. "It is increasingly clear that they are going to need a combatant with a very large radar to help take the fight to the enemy. Something to operate outside of threat waters but with a radar large enought to see over the horizon" said Steve Sloan, director and program manager for LPD 28/LX(R) programs.

The scale model on display was actually unveiled as the Ballistic Missile Defense (BMD) concept ship at Sea Air Space 2014. As we reported at the time, the LPD-based BMD ship was showing an impressive may be fitted with 288 Mk 41 vertical launch systems (or 144 Mk 57 as an alternative which are the VLS currently fitted on DDG1000 class).

The "Future Surface Combatant" now shows a reduced number of 96 VLS, "That's because the Navy told us they didn't need that many cells" Navy Recognition was told. The Ticonderoga-class cruisers are currently fitted with 122x Mk 41 VLS cells.


HII's Future Surface Combatant at Sea Air Space 2017.

The Ticonderoga-class cruisers will reach their retirement age of 35 years between 2021 and 2029, although the U.S. Navy may use upgrades to extend their lives to 40 years. The class was first ordered and authorized in the 1978 fiscal year. HII believes its LPD-based concept would be the right solution to replace the ageing cruiser class.

HII's concept ship offers many advantages. The huge (35') fixed S-band radar for starters, which is said to be 2000 times more sensitive than the current SPY-1. An X-band radar sits on top of the mast. A 3-face radar is available as an option to replace the large cubic radar. We were told that the LPD 17 hull form offers signiticant volumes to support other missions: There is provision for an elevator and below deck hangar, both large enought to accommodate V-22 tilt rotor aircraft. There is so much space in the boat valley and hangar space that the VLS cells may potentially be reloaded while at sea. If the aircraft elevator is not needed, the well deck may be retained to support special forces or other needs.

The model on display at the show was fitted with an optional 32MJ rail gun (forward, as main gun), a Mk110 57mm and a RAM launcher back aft for self defense.

In this configuration, the HII's "future surface combatant" is 209 meters (684ft) in length with a beam of 32 meters (105 ft) and a max. displacement of 27,000 tons. The speed is 20+ knots and expected crew is 161 sailors (a significant drop compared to the 300+ crew complement aboard the Ticonderoga-class).

Navy Recognition comment:
While the LPD 17 hull form is slower than the current CG class, the potential of a surface vessel fitted with the maximum size variant of the AN/SPY-6 AMDR radar and a 70+ day mission endurance (without resupply) sounds like a major capability step forward. Add to the mix a likely affordable design (because of the reduced crew and the hot production line) plus the ability to accomodate large, long endurance helicopters (an AEW variant of the V-22 or CH-53 would be ideal) to act as remote sensors, and you have what looks like a very promising CG replacement solution.

Marinha dos EUA estuda reativar oito fragatas ‘Oliver H. Perry’
14 de junho de 2017

A Marinha dos EUA está estudando reativar 8 fragatas da classe “Oliver Hazard Perry” (FFG-7) para conseguir atingir mais rapidamente a meta de 355 navios na ativa.

A informação foi dada pelo Chefe de Operações Navais, almirante John Richardson na terça-feira, falando diante de uma audiência no US Naval War College.

Richardson disse que os líderes estão buscando “todos os truques” para colocar mais plataformas na frota, incluindo trazer algumas OHP para o serviço e estender a vida dos destróieres da classe “Arleigh Burke” mais antigos.

“Será uma análise de custo benefício em termos de como podemos fazer isso. A outra parte é como fazemos a extensão da vida e como planejamos mantê-los por mais tempo. Vai ser dinheiro no banco se fizermos isso”.

Ele também disse que o início da extensão da vida útil planejada dos destróieres de mísseis guiados classe “Arleigh Burke” poderia ajudar a Marinha a atingir um total de 355 navios 10 a 15 anos mais rápido.

A última Perry deixou o serviço ativo na US Navy em 2015, com a maior parte da classe reservada para venda a Marinhas estrangeiras ou desmantelamento.
