美军这是下"核饺子"。 :)

美军的核潜艇在历史上,从来没有起到一次关键性的作用,纯属浪费钱

即便美军没有任何核潜艇,只要美国保持海军和陆军,没有一个国家敢核攻击美国,俄罗斯也不敢。

核潜艇有和没有一个样

美国现在有66艘攻击型核潜艇,没作用?

你说吧?有什么作用,即便美国没有这些核潜艇,全靠水面战舰,谁敢动美国海军?

潜艇最重要的作用是潜伏偷袭,是弱国海军需要的东西,美海军不用偷袭也能控制局面
扎心了老铁
首轮对陆地高价值目标精确打击最安全的方式。想想美潜艇首轮发射出4000枚巡航导弹雨,谁扛得住

首先,美国核潜艇只有很少一部分改造装巡航导弹,根本装不了这么多,而且用潜艇发射巡航导弹,成本高,需要水面战舰和空中配合

需要水面战舰和空中配合,还不如直接水面战舰发射,这也是美国几次战争中主要采用的手段.

核潜艇装导弹和发射导弹以及他巡航维护的费用远大于水面战舰,既然水面战舰和舰载机有导弹和精确制导炸弹.干吗用这么贵的东西?

都能射。而且有4艘专门战斧巡航导弹核潜艇俄亥俄,每艘射150枚

其它射的少

水面舰艇目标大,显眼。战争讲究多项选择,不是能用一种,就排斥其它

每艘射150枚, 需要多长时间?

弗吉尼亚级每艘12枚战斧导弹,加上俄亥俄级4艘改装,每艘154枚战斧

偷袭确实潜艇占优,不过美国要不占据海上优势和空中优势,美国是不会打仗的

算起来,远远不到4000枚,差的很远了

扎心了老铁答不出, 每艘发射154枚战斧, 需要多长时间?

一次齐射大概1000多枚。也许算上导弹补给船再装填,有可能4000枚

导弹可以齐射
扎心了老铁
潜艇偷袭完,海空就占优了

Navy Plans Massive Acceleration in Adding Attack Submarines The Navy has formally proposed to increase yearly construction of Virginia-class submarines staring in the 2020s. 10 hours ago  

A newly completed comprehensive Navy analysis says producing more Virginia-Class attack submarines on a much faster timetable is "achievable" and necessary to ensure future undersea dominance for the US - in an increasingly contested strategic global environment.  

The Navy report, titled The Submarine Industrial Base and the Viability of Producing Additional Attack Submarines Beyond the Fiscal Year 2017 Shipbuilding Plan in the 2017–2030 Timeframe, was delivered to Congress on July 5, 2017, Navy officials told Scout Warrior. 

The current or previous status quo had been for the Navy to drop from building two Virginia-Class boats per year to one in the early 2020s when construction of the new Columbia-Class nuclear armed submarines begins. 

The completed study, however, maintains that the Navy and industry can produce two Virginia-Class boats and one Columbia-Class submarine per year, increasing the current plan by one Virginia-Class boat per year. 

Navy leaders have consistently talked about an expected submarine shortfall in the mid 2020s and that more attack submarines were needed to strengthen the fleet and keep stay in front of near-peer rivals such as Russia and China.

"The sustainment of the two per year Virginia-Class submarine production rate during the procurement years of the Columbia-Class SSBNs is achievable and provides significant benefit to the Navy and the SSN (Attack Submarines) force structure," Lt. Lauren Chatmas, Navy Spokeswoman, told Scout Warrior in a written statement. 

Maintaining a two-per year Virginia Class build-rate will help the Navy reach its goal of 66 SSNs, as identified in the December 2016 Force Structure Assessment, Chatmas added.

 Increasing production will, to a large extent, rely upon the submarine-building industry's capacity to move up to three submarines per year.

"Producing these additional submarines will be a challenge to the submarine industrial base that can be solved only if the shipyards are given sufficient time to adjust facility plans, develop their workforces, and expand the vendor base," Chatmas said.

The Virginia-Class Submarines are built by a cooperative arrangement between the Navy and Electric Boat, a subsidiary of General Dynamics and Newport News Shipbuilding, a division of Huntington Ingalls Industries.

Each industry partner constructs portions or “modules” of the submarines which are then melded together to make a complete vessel, industry and Navy officials explained.

Virginia-Class Attack Submarine Technology

Virginia-Class subs are fast-attack submarines armed with Tomahawk missiles, torpedoes and other weapons able to perform a range of missions; these include anti-submarine warfare, strike warfare, covert mine warfare, ISR (Intelligence, Surveillance, Reconnaissance), anti-surface/ship warfare and naval special warfare, something described as having the ability to carry and insert Special Operations Forces.  

"Future Virginia-Class submarines (VCS) provide improved littoral (coastal waters) capabilities, sensors, special operations force employment, and strike warfare capabilities, making it an ideal platform for the 21st Century security environment," Chatmas said. 

Compared to prior Navy attack subs like the Los Angeles-Class, the Virginia-Class submarines are engineered to bring vastly improved littoral warfare, surveillance and open ocean capabilities, service officials said.

For instance, the ships can be driven primarily through software code and electronics, thus freeing up time and energy for an operator who does not need to manually control each small maneuver.

The Virginia-Class submarine are engineered with this “Fly-by-Wire” capability which allows the ship to quietly linger in shallow waters without having to surface or have each small move controlled by a human operator. With this technology, a human operator will order depth and speed, allowing software to direct the movement of the planes and rudder to maintain course and depth. 

Also, unlike their predecessor-subs, Virginia-Class subs are engineered with what’s called a “Lock Out Trunk” – a compartment in the sub which allows special operations forces to submerge beneath the water and deploy without requiring the ship to surface.

Unlike their “SSBN” Columbia-Class counterparts to be armed with nuclear weapons, the Virginia-Class “SSN” ships are purely for conventional attack, Navy officials said.

Development of Virginia-Class submarines are broken up into procurement “Blocks.” Blocks I and II have already been delivered. 

The Block III subs, now under construction, are being built with new so-called Virginia Payload Tubes designed to lower costs and increase capability.

Instead of building what most existing Virginia-Class submarines have -- 12 individual 21-inch in diameter vertical launch tubes able to fire Tomahawk missiles – the Block III submarines are being built with two larger 87-inch in diameter tubes able to house six Tomahawk missiles each.

Although the new tubes were conceived and designed as part of what the Navy calls its “Design for Affordability” strategy to lower costs, the move also brings strategic advantages to the platform, service officials say.  Specifically, this means that the submarines are constructed such that they will be able to accommodate new technologies as they emerge - this could mean engineering in an ability to fire upgraded Tomahawk missiles or other weapons which may emerge in the future. 

"VCS are designed to remain current with technology advances for their entire operational life through extensive use of modular construction, open architecture design (uses industry common design), and commercial off-the-shelf components," Chatmas said. 

The Block III Virginia-Class submarines also have what’s called a Large Aperture Bow conformal array sonar system – designed to send out an acoustic ping, analyze the return signal, and provide the location and possible contours of enemy ships, submarines and other threats.

Virginia-Class Block V - Virginia Payload Modules

For Block V construction, the Navy is planning to insert a new 84-foot long section designed to house additional missile capability.  “Virginia Payload Modules.”

The Virginia Payload Modules, to come in future years, will increase the Tomahawk missile firepower of the submarines from 12 missiles up to 40.

"The VPM submarines will have an additional (approximately 84 feet) section with four additional Virginia Payload Tubes (VPTs), each capable of carrying seven Tomahawk cruise missiles, for a ship total of 40 Tomahawks," Chatmas said.

The idea is to have additional Tomahawk or other missile capability increased by 2026, when the “SSGN” Ohio-Class Guided Missile Submarines start retiring in larger numbers, he explained.

Early prototyping work on the Virginia Payload Modules is already underway and several senior Navy leaders, over the years, have indicated a desire to accelerate production and delivery of this technology – which will massively increase fire-power on the submarines.

While designed primarily to hold Tomahawks, the VPM missile tubes are engineered such that they could accommodate a new payload, new missile or even a large unmanned underwater vehicle, Navy officials said.

The reason for the Virginia Payload Modules is clear; beginning in the 2020s, the Navy will start retiring four large Ohio-class guided-missile submarines able to fire up to 154 Tomahawk missiles each. This will result in the Navy losing a massive amount of undersea fire power capability, Navy officials explained.

From 2002 to 2008 the U.S. Navy modified four of its oldest nuclear-armed Ohio-class submarines by turning them into ships armed with only conventional missiles -- the USS Ohio, USS Michigan, USS Florida and USS Georgia. They are called SSGNs, with the “G” designation for “guided missile.”
