Continued from invitation thread.

Over the last few years, GM has been devoting large amounts of time and money in order to increase its naval capabilities. We are currently involved in programs dedicated to the creation of an effective submersible supply\hospital ship (which may be unveiled to the public for the first time at this conference) and a next-gen attack sub with Zoogie. Domestic projects include programs for advanced frigates, cruisers, and destroyers. Our goal is to create ships that are faster, stealthier, more survivable, and better equipped for dealing with enemy craft as new threats emerge. Among our recently unveiled craft are the Manta class fast attack minisub, the Teo class trimaran (three-hulled) battleship, and the Warlord class heavy fire battleship, all of which will be on display for the attendees of this conference.

Manta class fast attack minisub
Length: 40 feet
Height: 9 feet
Width: 30 feet
Max speed with standard armament: 60 knots
Max Operating Depth: 700 feet (home sub may not go below this depth either, or the mini sub will be crushed)
Crew: 3
Combat Radius: 100 miles
Armament: 10 horizontal launch tubes, which can hold any tube launched weapon under 20 feet in length, including Mk. 48 and torpedo tube launched Tomahawk cruise missiles. Tubes can be simultaneously fired. No added storage. Comes with Mk. 50 torpedoes.
Cost: 525 million, 10% discount to regional allies.

Deployed from a larger sub, this vessel's speed and ability to empty all of its weaponry at once makes it perfect for fast hit and run attacks on enemy coast lines. The high amount of noise it generates while operating does not matter in most cases, because its amazing speed enables it to outrun most torpedoes. In fact, this speedy ship is able to become completely airborne for a very brief moment when performing an emergency rise at full speed. Its immensely powerful but small and quickly draining fuel cell leads to a short combat radius, which in turn requires it to return to the "mother" sub or base very often for refueling, limiting it to fast attack and return missions, close quarters aid for battles with other subs, and close range coastal defense.

We are currently experimenting with alloy hull designs to increase the crush depth of the Manta, as well as new fuel sources to extend its range. Our goal is to create a new model Manta capable of operating indepently for extended periods of time, as well as not hindering any larger subs it may attach to.

Beam: Main Hull: 120 feet With outer hulls: 170 feet
Draft: 30 feet
Max Speed: 36 knots
Side Armor: 27 inches
Deck Armor: 20 inches
Outer Hull Armor: 20 inches
Armament: Twelve 16"/50 caliber guns mounted in four triple turrets. Thirteen 5"/38 caliber guns in four triple turrets and one single turret. Four Armored Box Launchers capable of carrying 16 Tomahawk cruise missiles. Eight Harpoon antiship missile quad launchers. Six Evolved SeaSparrow missile launchers. Four 64 cell Mk. 41 VLS systems. Four Mk. 32 triple SVTT. Two 660mm torpedo tubes mounted in each of the outer hulls. Eight Phalanx 20mm CIWS.

The Teo is the pride of the Great Matean Navy. The trimaran design not only increases survivability and speed via added buoyancy, but it greatly increases the Teo's ability to carry weaponry. This ship features a variety of anti-surface, anti-air, and anti-sub systems, thus enabling it to defend itself from virtually any attack. New development projects for the Teo include advanced alloy construction methods to increase the armor and structural strength of the ship, automatic CIWS designed for under water use (think Phalanx on the underside of the ship, and with anti-sub weapons), and new composite armor designs to reduce the amount of solid steel and thus mass the Teo has.

Cost: $5.1 billion. 10% discount to regional allies.

Latest GMI ship design. The Warlord, designed to enable fleets to deal with the massive super-battleships of the NS world without themselves having to create a super-ship, is neither the fastest nor most greatly armed vessel on the sea, but can deliver fatal blows to nearly any opposing ship with 1 or 2 rounds from its massive 25 inch guns. Belt armor more than 3 feet in thickness enables the Warlord to withstand nearly any form of attack.

Modifications for the brand new Warlord are already being developed, mainly focused on decreasing the size of ETC firing systems in order to increase the power of the Warlord's guns without requiring larger diamater guns, and the development of mesh-and-reactive armor systems to decrease the amount of actual solid steel needed on the ship, thus decreasing its mass and increasing its mobility performance.

Great Mateo, we are especially interested in that minisub.

Our minisub is much more of a minisub, with limited arnament and a slow top speed. Your sub, however, looks capable of even outrunning torpedoes etc. A couple of questions first:

How long can it maintain top speed, with arnament?
What is its engine?
What sort of mother ship are we talking of?

We may have questions later. But first, we must say we are dazzled by your battleships - though the BB has lost its role, it is still a warship to be feared.

Ah, your subs look very interesting. I'm sure I've seen them earlier this year? Well we have created our own small attack sub, as well as a aircraft carrying sub. Unlike you, we unfortunatley haven't been supplied with pictures of these vessels so we regret to inform the conference that these are pure stats:

Furol class Submarine Carrier

With the increase in surface warfare ships, a carrier was needed that was capable of diving below the water. There were many problems that were associated with this kind of project so many years of research and development was spent on it. This is the result.

The Furol is a large submarine that has two small con towers on either side of the hull, to allow for the landing strip. The landing strip itself is covered by a protective outer hull, that slides into the main hull when on the surface and preparing to launch aircraft. This prevents the air strip from getting overly wet, and decreases the chances of accidents on wet surfaces. There are several elevators along the air strip to allow several VTOL aircraft to be deployed at once, without having to wait for one or two elevators at the back. The middle and fore elevators can be locked if STOL aircraft are being used.

Skiy class Submarine

A mobile, one person submarine, the Skiy was designed for special operations. Once its test period was over the usefulness of such a vehicle was undeniable, so it was mass produced for combat. Its original design had little in the way of weaponry, however once the re-design was done, more systems were attached to make it more deadly. The main advantage the Skiy has is its window. This allows the user to approach and determine the best way to attack using their own eyes. It also allows a quicker reaction time to various threats that can make themselves apparent.

Just under 1 1/2 hours with standard sub combat armament of 6 Mk. 50 torpedoes and 4 Mk. 48s.

At the moment, the Manta is powered by a series of waterjet turbines feeding off of a small hydrogen fuel cell.

GM currently uses and sells specially modified SeaWolf class attack subs as mother ships for the Manta. The attack sub we are developing with Zoogie is going to replace this, though. In special cases, we have modified Ohio and Typhoon class ballistic missile submarines.

Bump for naval tech sharing\displaying.

Another BUMP for the conference.

Durtistan Arms presents the following systems:

Sting Ray

Sting Ray is a lightweight torpedo for carriage by aircraft (fixed-wing or rotary) and surface ships for use against submarine targets. It is electrically propelled and powered by a sea water battery which combines low-noise and manoeuvrability with a high speed and deep-diving capability. It is an autonomous weapon which, having received initial, pre-launch, environmental and target information from its launch platform, uses its active sonar and tactical software to search for, localise and prosecute its submarine target. Its tactical software provides the tactical algorithms needed to deal with complex countermeasure scenarios.

Sting Ray has a diameter of 12.75 inches and a length of around 8.5 feet

http://www.mindspew.com/durtistan/stingray.jpg


SAWCS

SAWCS is intended to detect, classify and localise torpedoes that have been deployed in the vicinity of own submarine and then to determine the level of threat that each one poses. It will generate and recommend a tactical plan to evade these torpedoes, which can, dependant on the scenario, include the deployment of acoustic countermeasures and the execution of manoeuvres by own submarine. Once a tactical plan has been approved by the command, the system will, under control of an operator, automatically deploy countermeasures in accordance with that plan. SAWCS will always be an advisory system: no plan will be implemented without positive approval by the Command. A subset of this capability which provides just the ability to program and launch the countermeasures using the Stores Control Unit (SCU) will be fitted to some platforms either ahead of or instead of the full capability previously described. This latter subset is known as SAWCS Partial Fit which is in service.

SCAD200

The Submarine Countermeasure Acoustic Device (SCAD200) is an under casing launched acoustic countermeasure designed to counter hostile platform sonar. The smaller SCAD101 is used to defeat acoustic homing torpedoes. The SCAD 102 is functionally the same as the SCAD101 but can be launched from within the submarine.

Each platform installation comprises a number of cradles which are permanently installed under the casing. These cradles are the mountings for the SCAD 101 and 200 Launchers within which the countermeasures are housed. The launcher and countermeasure are delivered fully assembled and are a one shot device. The countermeasures are fired into the water by means of a Gas Generator that is fitted within the Launcher. Once in the water the countermeasure descends or ascends to the programmed operating depth and then hovers. Acoustic transmissions then continue for the designated period. On completion the countermeasure automatically purges itself of data and scuttles.

We are also proud to announce the Aiglos Systems 7000 series Sonar.
This is a fully integrated active and passive sonar system for deployment in three main platforms.

Sonar 7076 is a dedicated hunter system. The 14,000 hydrophones present in the Durtistan Arms Astute class SSN is the most sensitive hunter system that we are aware of.
7076 was created to track and target modern stealthy submarine designs in addition to surface ships. The hydrophones are only part of the system, however; the main innovations lie in signal processing and recognition allowing the Sonar to identify and track targets at extreme ranges. In one test, the Sonar demonstrated a range of over a hundred nautical miles and, in ideal conditions, was able to pull the acoustic signiture of one vessel out of a busy commercial harbour from a distance of 80 miles.

Sonar 7077 is a mine hunter for deployment in dedicated mine hunting units and is currently under test.

Sonar 7078 is a surface vessel platform intended to do for the Anti-Submarine frigate what 7076 does for the SSN. The key capabilities are sensitivity and range, allowing an ASW vessel to identify and track threats well before they reach firing range. The rapid prosecution of submarine threats is key to suucessful escort and convoy protection duties.
This is also in the test phase.

Bump.

OOC: If I don't have too much homework tomorrow, you can expect GM to display one or more of its frigate, cruiser, and destroyer designs.

Bump. All right, slight change of plans. Display of new ships by Friday night, guaranteed.

Where are our other promised attendees?

GMI's display for our new destroyer is fully complete, however, due to clauses in the charter of one of our alliances, this design may not be shown to the public for another 48 hours. The design shall be unveiled in this thread Sunday night. Thank you for your patience.

TAG, will post later.

As it has recently been released (friday night)Ii am going to show you the new Tartaros WIG craft the Jordaxia and I have designed:

PX-602 'Tartaros' WIG Batleship
http://www.bateshome.com/jordan/wigbattleship6.jpg
Designed by various CAP members, this is a revolutionary new wing-in-ground effect craft. Able to move at high speed, it can deploy its 4 main guns to effective results, and then re-deploy before counter-attacks can be made.

Unfortunately these main guns cannot be fired while in cruise mode, and so several missile pods have been installed to allow attack while in the move. Various Goalkeeper and Metalstorm systems keep this safe from aerial units.

Another addition to the Tartaros is its C&C capabilities. Able to control various UAV's and co-ordinate attacks, it is a good vehicle to station your C&C abilities.

Designed by: Jordaxia, Phoenixius, New Empire
Function: WIG Battleship
Powerplant: Nuclear reactor
Propulsion: 20x jet engines

(Classified as Tartaros-M)

Blasphemy. The Battleship has not lost it's role, it still has a niche that cannot be filled by other vessels on the sea. Not going to argue about it right now, I got work - but later.

This has been an OOC post by Doujin

As promised, GM's latest destroyer design:

http://www.fas.org/man/dod-101/sys/ship/dd-21-pict-litoral-s.jpg
Hitokiri class rail gun destroyer
Length: 570 feet
Beam: 65 feet
Speed: 32 knots
Armament: One 5"/50 caliber electromagnetic rail gun. One 64 cells and one 128 cell Mk. 41 VLS. One 155mm Advanced Gun System. One Goalkeeper 30mm CIWS. One Kashtan ADGM (Two 30mm Gatling guns and a cluster of 8 SAMs). Two Mk. 32 SVTT.
Crew: 175
Cost: $1.3 billion.

GM's new next-gen destroyer. The 5 inch rail gun has a range of up to 290 miles and launches its tungsten alloy rounds at a speed of Mach 7. Power for the rail gun is diverted from the drive system during firing, requiring the Hitokiri to coast while using its main weapon. The rounds use no explosive warheads or charges for firing; the speed of the round upon impact creates roughly the same damage as a Tomahawk cruise missile. The lack of explosives greatly increases safety, as crews no longer must worry about the ammunition for the main guns detonating. The AGS is a development of Army artillery pieces and can fire on targets up to 116 miles away and at a rate of 12 rounds per minute. The unique design of the Hitokiri greatly reduces its radar cross section, making it stealthier than any previous destroyer. The automation of many features also greatly reduces the need for human attention, allowing the crew of the Hitokiri to be reduced to a minute 150.

Developments for the Hitokiri are centering around improving the rail gun itself. We've been having higher than average barrel damage due the friction of the metal armature that carries the round down the barrel dragging against the sides. We're currently experimenting with a wide variety of low-friction lubricant and ball-bearing set ups in an effort to reduce this. We are also currently experimenting with a wide variety of power sources in an attempt to keep at least some power diverted to the screws while the gun is firing.

Are you talking about a magnetic rail gun there?

How did you make that work? I know that's probably secret but I'm fascinated. I'm also interested in how you mask that field so it doesn't kick off every MAD system in the area! :lol:

Ahh ignore me. I'm just jealous. The best Durtistan ever achieved was to be able to site a prototype railgun on a testbay and watch it spontaneously disassemble itself after the fifth or sixth firing. We never got the material tolerances right.

GM - the AGS is not a rail gun.. and it would take more than propulsion power to fire it.

GM - the AGS is a rail gun.. and it would take more than propulsion power to fire it.

OOC:

No, it's not. AGS is a standard 155mm howizter modified for naval bombardment and possible autonomous fire that uses specially designed ammunition.

Also, a ship very much like this is in development as part of a joint venture between the US Navy and the Royal Navy. The ship is designed to divert power from the screws to the 5 inch rail gun during firing. So please, inform the weapons designers who have already produced a functioning scaled down model that was able to fire projectiles at up over Mach 6 that this is impossible. I'm sure they'd love to hear it and stop wasting their time and money.

I'm still amazed, but this is the sort of breakthrough that the conference was intended to bring out into the open.

So here are some questions that have been giving the designers at Durtistan's Deep Six Sea Warfare Systems headaches for months.

1: Afloat Prepositioning Squadrons require escorts or they are terribly vulnerable. The function of such ships precludes stealth since they are required to haul materiel and the more they haul the better. How can you move a significant number of troops (division strength or better) by sea without attracting the attention of hunter forces?

2: Modern carriers have flight decks that are just big enough for a C-130 to land on, but not without great difficulty (OOC: done a dozen years ago when the USAF put a C-130 down on the USS Forrestal). Since the C-130 is the most common intratheatre logitics platform, is there a way of staging them from an assault carrier without making the ship VAST?

Who are you asking Durtistan?

1) Zoogiedom, New Empire, and myself are currently designing a large submersible replenishment vessel\hospital ship that (hopefully *crosses fingers*) will be on display at the conference prior to its end. While the vehicles would most likely be a problem, the troops would most definitely not be.

2) The answer to this dilemna is more than likely no. While you could permit C-130s to easily take off and land without increasing size by much, the space that C-130s require when parked would require an immense expansion of the vessel.

And to answer the earlier question, the rail gun works by diverting electrical current intended for the drive system up a series of rails along the barrel of the gun, creating an electromagnetic field. The metal armature that slides up and down the barrel, which holds the round, is then hyperaccelerated by the field down the barrel, flinging the round free at a speed of Mach 7.

As for MAD, it is not a large concern at the moment. MAD is designed for close range detection, primarily for determining the exact location of a submerged vessel prior to an attack, and is largely uneffective for wide range searches. At the distances needed for MAD to effectively detect and pinpoint the location of any surface ship, the ship would already be in visual range.

The answer to this dilemna is more than likely no. While you could permit C-130s to easily take off and land without increasing size by much, the space that C-130s require when parked would require an immense expansion of the vessel.

Clan Smoke Jaguar have approached the problem with a modular supply base which looks like it was founded on oilrig engineering principles but it's static and wopuld almost certainly tie down a squadron of frigates or destroyers to protect it.

I think I'm going to have to bite the bullet and create a supercarrier or work on a different way to transport and deploy troops. Either way, it'll be in the works for quite some time.

I wouldn't use a sub platform for troop deployment. Too much in the way of life support requirements and the potential for stir craziness among the transported troops. We've looked into the psychology when we toyed with the idea of an entirely submarine fleet.

Bump.

Bump.

Wow, this died.

Personally, I haven't had much time. Most of my current projects have been suspended until finals are over. I might do so over the weekend, but no promises. I think that's why no one is posting.
