Los Angeles class nuclear powered fast attack submarines of US Navy

Los Angeles-class (SSN688) submarines form the backbone of the U.S. Navy's nuclear-powered attack submarine fleet; it is the class that has more operating nuclear submarines than any other in the world. Their primary missions are to hunt enemy submarines and surface ships, launch cruise-missile strikes on land-based targets and gather intelligence. The boats were designed by General Dynamics Electric Boat and they are divided in three flights (Flight I, II and III) based on improvements in their design and equipment such as electronics, armament and characteristics. The Flight I consists of 31 submarines (only 11 are active, in commission), the Flight II have a 12 Vertical Launch Tubes (VLS) for Tomahawk missiles and it consists of 8 submarines (all in active service) and the final Flight III consists of 23 submarines of which only one has been retired. The final 23 submarines of the 62-ship class are known also as improved 688s (688i). These are quieter and they are equipped with more advanced electronics and sensors as well as retractable bow planes (and not on their sails like the other Flights) and hardened sails to break through ice during Arctic operations.

The boats have a displacement of6,900 tons while submerged, a length of 110 meters, the maximum diving depth is +400 meters and they can achieve a speed of 20 knots surfaced and 25+ knots submerged (they are reports about an achieved speed of +33 knots!). The endurance is 90 days. The crew consists of about 130 enlisted crew members (16 officers). The boats have four 21 in (533 mm) torpedo tubes while the armament consists of 37 Mark 48 anti-submarine torpedoes, Tomahawk cruise missiles, Harpoon anti-ship missile and mines.

Virginia class nuclear powered fast attack submarines of US Navy

Virginia class submarines are the latest nuclear attack submarines operated by US Navy. They were conceived as a less expensive alternative to the Seawolf class attack submarines and they are planned to replace the older of the Los Angeles-class submarines. Below a great work by Stephen Rountree for U.S. Navy, General Dynamics Electric Boat Corporation and Newport News Shipbuilding.


And a photo of the lead ship of the class, USS Virginia (SSN-774), while she returns to the General Dynamics Electric Boat shipyard following the successful completion of its first voyage in open seas called "alpha" sea trials, in July, 2004.

US subs are pretty cool, but I just wonder how many of our tax dollars are going for neat new naval frigates, aircraft carriers and some of the missles and more expensive weaponry that is out there. I mean couldn't the money be better spent elsewhere? I can not even imagine the cost of all these instruments of battle. Defense spending has to be overwhelming.

Really informative stuff, especially that chart of US subs through the ages.

I'm really surprised to see that torpedoes are still used by modern subs. With anti-ship missiles and other advanced weaponry, I was almost certain that torpedoes had been phased out.

I agree I enjoyed seeing the history of the submarine. I think that they still use torpedoes because they are the most efficient for firing under water. Having do deal with both water and air resistance is something that destroyers don't and above water ships don't have to deal with. Torpedoes have come a long way though and are extremely intelligent nowadays.

Ever since I was a little kid I have always has a fascination with the submarine and other sea based vehicles. I think I just saw a movie once and that really got me going, but it has lead me to this point so I cannot argue with it. Submarines really do have an interesting history, both in war and other areas, and I always enjoy reading up on some.

These are impressive naval attack equipment. Their construction also calls for an, even more, impressive amount of funding. The development of each new class of these weapons comes with a higher level of sophistication. I am waiting to see if they might eventually be equipped with amphibian capabilities.
It might be an unusual expectation given the size of these crafts. However, nowadays, don't rule out anything as possible.

"NEYK" is a sophisticated and deadly mini submarine build by OCEAN SUBMARINE, Netherlands.
Primarily designed for SOF with its ability to be launch from Landing Platform Docks and the only submarine with the ability to walk on land using landing gears. NEYK is in the process of development to be launched in january 2018. Availables in two version for Navy's and Coastguards.

Introduction:

The newest type NEYK submarine with a fully pressurized single hull has excellent military capabilities. With an overall length from 19m (63ft) to 22m (73 feet) and has excellent stealth features and a very low noise profile. It has the capability to bring a complete team of Navy Seals and all its equipment undetected to almost on shore of any place on earth. Its standard diving capability of 300m (1000 feet) can be upgraded. But the Marine version of our NEYK also can deploy a lot of other military tasks. From gathering intel to active warfare.

Either for gathering information or tactical purposes the NEYK submarines will be a weapon system of its own kind. It can deploy a rapid force on any coast for infiltration or retracting purposes. It can be fitted with an extra layer of stealthy provisions. It primary and secondary weapon system are very versatile. But most of all its compact size, very low noise profile and incredible agile manoeuvrability will help every submarine commander to get his task accomplished.

The NEYK can be equipped with various weapon systems. Most likely the Navy version of our NEYK will be fitted with two launching tubes for either all types of torpedo’s or mines and missiles. Besides that, it can also be rigged with various kind of defending weaponry.

The “NEYK” combat system provides the best platform for processing all gathered intel. The NEYK can function as an unseen sentinel collecting all kind of e-lint by any system you wish or eyeballed reconnaissance by its strong tactical periscope. And it can do that for a long time without surfacing.

The customer can have a choice of any combat system he likes with every type of sensor passive active ranging or intercept. This can go from a cylindrical array sonar, passive sonar, echo sounder, Intercept sonar, active sonar, self-noise indicators and all types of navigation and communication systems, standard underwater telephone, various radar systems and tactical night vision equipment for the periscope.

Design
The NEYK by Ocean Submarine is modularly built and comes with a single pressure hull. The hull is reinforced with rafters spaced at 60 centimetres apart for maximum security. The overall design guarantees a very low hydrodynamic drag, a high shock resistance and a very low noise signature. The bow section varies to order. The submarine has spaciously dimensioned panoramic acrylate portholes for excellent sight from the cockpit. With its hydraulically driven retractable undercarriage The NEYK is the only submarine that can land by driving up a ramp by itself.

The new NEYK submarine is completely built modular. The private versions have a single pressure hull that is only slightly tapered in the rear for maximum inner space. That is where the oxygen bottles are stored. All parts as mid ship, conning tower, stern and bow sections are made of high-yield steel HY-100 (produced by Marel to meet RNIN specifications).

The bow section is not welded but bolted to the hull and can vary to order. For military use is it is likely fitted with a steel version that can contain weapons or electronics.

The NEYK can easily be airlifted to any place in the world. To transport the vessel, the vertical diving rudders and the complete tower can be removed within one hour only. The three retractable wheels with hydraulic propulsion gives the submarine the possibility to drive up any elevations up to 7 degrees such as ramp. The complete submarine can drive itself into a transport airplane like a C5-Galaxy or Antonov An-225.

Comfort
Every submarine commander will love our Navy version of the NEYK series for its highest achievable comfort for his crew and its excellent handling. The revolutionary steering design makes the vessel the most agile submarine ever made. All integrated electronical control and monitoring systems makes the submarine completely operated by wire and easy to handle with only two joysticks. That makes manoeuvring very precise and predictable. The NEYK either can turn on its keel within seconds or hoover within centimetres at one spot.

The NEYK submarine can be rigged as a fast stealthy and deadly naval force to be reckoned with.

It really is the most agile underwater vessel ever build. Due to the two separately placed main engines that separately can be reversed, four vertical diving rudders and a main rudder, a bow and a stern thruster the whole submarine can turn on a dime in only seconds. And this without causing cavitation. Hoovering is also brought to the next level. The NEYK can stay actively in one place by the use of two extra vertical thruster placed in the dome on top of te tower that can give up and downforce. It can do this completely computerised at pre-set parameters.

For any Navy men on a high risk mission, the absolutely stealth concept will be a real reassurance. Also its very rugged design will be very comforting. The NEYK is a boat that can endure a beating. And think about installing provisions like high pressure chamber with inside an air lock and to the outside an extra hatch to let divers in and out under water. That hatch also can be of great value in rescuing other submarine crews if necessary.

Viewport
The large spherical top viewport provides the pilot with excellent all-round visibility

Power and propulsion
The main propulsion of the NEYK is provided by two electrical nearly noiseless motors that are placed in two pods outside the pressure hull. The pods are specially designed to give the propellers more efficiency up to five percent and provide extra cooling at low speed. The revolutionary design also provides low drag and a very low underwater noise signature.

The electrical power is generated by a diesel engine. The engine provides the power for the electrical main propulsion and bow, stern and vertical thrusters when surfaced or at snorkelling depth and charges the batteries.

Ocean Submarine provides the diesel driven Rolls-Royce 4000 U83 generator as a standard. Other makes of engine can also be built in. For the electrical propulsion we use 100 kW motors as a standard. However, more powerful engines or more recreational types can be ordered.

FT-2017-007-A030.xar_.jpg


Extra features
Standard the NEYK submarine comes fully navigable with all necessary navigation systems, a fully integrated periscope, systems for surface and under water communication and safety equipment. But our NEYK submarine is a very flexible diving platform. Every vessel is unique and can be rigged with almost every piece of equipment to meet even the most demanding customer requirements.

Ocean Submarine also provides the necessary training and certification of the crew.

Looks good and dandy but no way its going to rival submarines build by U.S/Germany/France. It will mostly be used for quick mission execution thanks to its mobility and stealth tech however it can not be considered a backbone type of sub.
