A mais bonita classe que alguma vez navegou os nossos mares.

De facto são navios impressionantes... e segundo se diz podem ser reactivados em caso de guerra, tal como foi na Guerra do Golfo.

Concordo com o nelson, sem dúvida os mais belos navios de sempre! Ainda me lembro quando um deles (o Missouri, se a memória não me falha) veio a Lisboa nos anos 80. Mais tarde, quando estava a viver na área de São Francisco, via regularmente, e com muita tristeza, o pobre do Iowa a apodrecer na baía.

Foi o ultimo a ir para museu (agora está em L.A,). O curioso é que assim que a US Navy liberou os navios para serem museu choveram interessados. Foi uma guerra...

By 2012, all four Iowa-class battleships were stricken from the US Naval Vessel Register and had become museum ships accessible to the general public.http://ww2db.com/ship_spec.php?ship_id=800

Provavelmente o momento mais negro da historia destes couraçados foi a explosão da Torre 2 do USS Iowa, onde faleceram 47 membros da tripulação:  http://en.wikipedia.org/wiki/USS_Iowa_turret_explosion

Navy Spends $1.6B to Upgrade Carrier and Amphib Ship Defenses

The Navy is working on a $1.6 billion technological upgrade overhauling ship defense systems onboard amphibs and aircraft carriers to include interceptor missiles, streamlined radars and software improvements, service officials said.

The work is being done on what’s called Ship Self Defense Systems, or SSDS – a series of integrated technologies being upgraded to track, identify and destroy a wide range of possible threats such as incoming enemy supersonic missiles.

“I’m upgrading the SSDS to handle the Joint Strike Fighter and to handle higher threats. My primary upgrades with SSDS are getting an upgrade to be able to handle supersonic targets,” said Rear Adm. Peter Fanta, director of Surface Warfare.

Some of the key elements to the upgrade include getting the ship ready for upgraded missiles such as the Evolved Sea Sparrow Missile Block 2, or ESSM Block 2, and Block 2 of the Rolling Airframe Missile, or RAM Block 2.

Both missiles, already in limited or early production, are engineered to protect carriers,amphibious assault ships and other vessels from cruise missiles, small boat threats and airborne enemy threats such as aircraft or UAS.

The new RAM Block 2 variant includes a new RF receiver, new navigation system and increased diameter to 6-inches, Raytheon officials said. The weapon has a dual mode RF and IR guidance system. The Block 2 missile is 9.45 feet long, weighs 194-pounds and is able to reach supersonic speeds, according to Raytheon and Navy information.

The new missile variant also includes enhanced guidance algorithms and a more powerful dual-thrust rocket motor enabling the missile to reach longer ranges, Raytheon officials said. Overall, the Navy plans to acquire at least 502 RAMs between 2015 and 2019, service officials said.

The Evolved Sea Sparrow Missile Block II, or ESSM, is a new version of an existing Sea Sparrow weapons system currently protecting aircraft carriers, destroyers, cruisers, amphibious assault ships and other vessels against anti-ship missiles and other surface and airborne  short-range threats to ships, Navy officials said.

The ESSM Block II is engineered with what’s called an active guidance system, meaning the missile itself can achieve improved flight or guidance to its target by both receiving and actively sending electromagnetic signals, said Raytheon officials.

The ESSM uses radar technology to locate and then intercept a fast-approaching target while in flight. The use of what’s called an “illuminator” is a big part of this capability, Raytheon officials said.

The current ESSM missiles use what’s called a semi-active guidance system, meaning the missile itself can receive electromagnetic signals bounced off the target by an illuminator. The ESSM Block 2’s “active” guidance includes illuminator technology built onto the missile itself such that it can both receive and send important electromagnetic signals, Navy and Raytheon officials explained.

“Block 2 relieves us of the requirement to do a lot of illuminator guidance as a short range self-defense. It has an active front end. That gives the fleet more options as there are going to be situations where you are going to want a semi-active guided but when you are dealing in a tough threat situation,” Rear Adm. John Hill, Program Executive Officer, Integrated Warfare Systems, told Military​.com in an interview.

The missile is able to intercept threats that are close to the surface by sea-skimming or diving in onto a target from a higher altitude, Navy officials explained.  The so-called kinematic or guidance improvements of the Block 2 missile give it an improved ability to counter maneuvering threats, Navy and Raytheon officials said.

ESSM Block 2 is being jointly acquired by the U.S. and a number of allied countries such as Australia, Canada, Denmark, The Netherlands, Norway and Turkey. All these countries signed an ESSM Block II Memorandum of Understanding, or MOU, designed to solidify the developmental path for the missile system through it next phase. The weapon is slated to be fully operational on ships by 2020.

As part of the SSDS overhaul, Navy leaders are now working on a wide range of software and hardware fixes to amphibs and carriers so that they can accommodate the upgraded RAM and ESSM missiles.

“From a combat systems perspective I am updating the software to be able to handle the speed and the ranges that those missiles can now function against. It is both software and hardware. I also have to upgrade the Sea Sparrow launchers to take the added weight of the Sea Sparrow Block 2, upgrade the RAM launchers to take the new RAM systems and I have to upgrade the radar to allow the data to flow back and forth,” Fanta said.

Fanta explained that a lot of the work relates to making sure the upgraded RAM and ESSM missiles can properly integrate into their missile tubes.

“I’m doing something within the software or the actual hardware of these systems.  A lot of it is algorithm work and a lot of it is making the launchers able to turn faster with more weight in each missile tube,” Fanta added.

The upgrades are also integrating a defensive weapon called Close-In-Weapons-System or CIWS, Navy leaders explained.

“It is a close-loop fire protection system all by itself. It has a radar and it has a gun. It is trainable and you can do different levels of integration with CIWS. It is either stand alone or it has some level of integration with the other sensors on board,” Hill said.

Hill also explained that the current SSDS upgrades included a technology known as Fire Control Loop Improvement, or F-CLIP, which involves the use of a common display system for different sensors and radar signals.

Breaking the Anti-Access Wall

Proceedings Magazine - May 2015 Vol.
141/5/1,347
By Captain Sam J. Tangredi, U.S. Navy
(Retired)
Reviving the forgotten ‘arsenal ship’ concept could give the Navy the edge in destroying an enemy’s communication and weapon systems.

Defeating an anti-access strategy requires three core capabilities. The first is the ability to neutralize the sensors of the anti-access force (to include the termination of the enemy’s satellites). The second is a robust layered defense that provides physical, electronic-warfare, and cyber-war protection for one’s own force. This capability should include the preplanning of autonomous actions by tactical units if/when force communications are lost. It must also include cutting-edge deception techniques. The third is the capacity to provide a precise, persistent, and continuous volume of fire directed at the enemy’s command-and-control (C2), communications nodes, and long- and mid-range weapon systems. Since some of the enemy’s systems can be expected to be mobile or hardened, this cannot be done in the “one bomb, one kill” fashion that is the full promise of smart weapons. Accurate targeting and smart weapons are essential, but volumes of (precise) fire with multiple striking salvos are also needed to paralyze and suppress the anti-access force.

Many articles can and should be written about all three of these capabilities. But the proficiency that appears most lacking in the U.S. naval arsenal today is the third: the ability to rapidly and repeatedly put multiple ordnance on target. There are too few missile tubes/launchers in the Fleet, and many of them must be filled with theater ballistic-missile defense, anti-satellite, anti-antiship ballistic and cruise missiles, and anti-aircraft weapons to provide the needed layered defense. In this scenario, the Navy requires launchers with strike weapons in abundance. This should drive us back to reconsidering the once-heralded but quietly discarded concept of the arsenal ship.

This is a project which was being developed by both the U.S. Navy and the Defense Advanced Research Projects Agency (DARPA) . It would be a vessel which carried hundreds of vertically launched cruise missiles of various types. They would be intended to operate forward in a manner which provides peacetime presence and crisis response in the event of a regional conflict. With massive firepower, the U.S. Navy hope to create the ability to halt a regional aggressor quickly, allowing time for a counter-build up of friendly forces

Many have even suggested that these vessels could be seen as modern day Battleships if built.

Navy retires the SH-60B Seahawk

SAN DIEGO (CBS - After 30 years of service, the SH-60B Seahawk Copter was retired on Monday after making its last flight.

A ceremonial day for hundreds of airman and sailors who retired the SH-60B Seahawk in a sundown ceremony in North Island.

Many said they stood on the shoulders of legends who flew on the aircraft over the last 30 years.

"For our venerable SH-60B, a great friend and she served the Navy very well,' said Captain Shawn Malone, USN, Commodore Helicopter Maritime Strike Wing Pacific.

For more than three decades, the SH-60B protected a legacy of airman and sailors, putting more than 3.6 million hours of service.

"For 32 years she has been protecting our nation's interest, and influencing the hearts and mind around the world where it mattered and when it mattered," said Vice Admiral Paul A. Grosklags, Deputy Assistant Secretary of the Navy Research, Development and Acquisitions.

The Seahawk was not only used in combat across the globe, but it was also deployed for hundreds of humanitarian efforts.

The Seahawk was replaced with the MH-60R Seahawk, described a quantum leap of technology for another legacy of airman and sailors.

The last active duty detachment of the SH-60B returned in April.

It was part of the helicopter maritime strike Squadron 49 based out of North Island who went on a seven month deployment in South America in a counter drug mission.

The Navy said San Diego residents will not notice a big change in how the MH-60R looks and flies because the biggest difference is in the inside and the technology.
