The EM-220 ‘Tigershark’ class diesel electric submarine type is the result of a very lengthy review into Elias Navy submarine operations. This review concluded that since larger SSNs such while being incredibly capable are prohibitively expensive to build in large numbers and not as useful in littoral waters where many of Elias Navy submarine operations take place. Therefore the decision was taken to develop a new type of diesel electric submarine that would offer a cost effective alternative to nuclear attack submarines and at the same time providing as similar capabilities as possible. The Elias Marine Corporation’s extremely experienced team then came up with a design that effectively crammed as many technologies and capabilities into as small a hull as possible. During design emphasis was also placed on secondary missions such as mine laying, Special Forces insertions, electronic intelligence and even search and rescue. Using extensive knowledge gained from experience with the 'Kilo' and 'Foxtrot' class submarines, the design represents a significant step forward in important qualities such as stealthiness, combat power and reliability.

Design

The Tigershark is designed for maximum performance with minimum acoustic signatures and features a teardrop shape hull constructed of a steel based alloy that offers significant advantages over steel without the huge price premium of titanium. The hull is covered in ancheolic sound absorbent tiles which prevent nearly all interior sounds from escaping.

The forms of the hull, the sail and the appendages have been specifically designed to produce minimum hydrodynamic noise. Between the suspended decks, the equipment is mounted on elastic mountings wherever possible, and the noisiest systems have a double-elastic mounting to reduce the risk of their noise profiles being radiated outside the submarine. The shock-resistant systems have been developed from systems incorporated in advanced nuclear-powered submarine designs. The low acoustic signature and hydrodynamic shock resistance give the class the capability to carry out anti-submarine and anti-surface ship warfare operations in closed or open sea conditions, as well as the capability of working with special forces in coastal waters.

One of the most easily detectable signs of submarines has always been the periscope that can show up easily on surface search radars but on the Tigershark the fibre optic is non hull penetrating and is covered in a RAM coating that makes a small radar cross section into a virtually non existent one. Additionally the periscope’s shape minimises visible wake on the surface. All other antennae and aerials that need to protrude above the surface at some stage all have these stealth features to minimise the risk of detection. These masts are also shaped to produce as little wake as possible, thus reducing the chances of aquiring the submarine visusally.

The submarine was designed with the object of having the least crew possible and using automated systems and eliminating certain jobs through technology. The compliment of the class need only be 31 with a standard watch team of nine although spare accommodation, in the form of fold down bunks for 16 is provided for missions such as Special Forces Insertion where additional personnel are required. All living and operational areas are fully air-conditioned. The vessel is especially equipped with all the necessary systems to provide vital supplies, water, provisions, regeneration of the atmosphere, to ensure the survival of all the crew for up to nine days in the event of an emergency where the submarine is stranded on the sea bed.

The ship is equipped with full rescue and safety systems. A connection point for a diving bell or Deep Submergence Rescue Vehicle (DSRV) allows rescue operations.


Command and Control

The combat management system, with up to six multifunction common consoles and a centrally situated tactical table, is collocated with the platform-control facilities. The combat management system is composed of a command and tactical data handling system, a weapon control system and an integrated suite of acoustic sensors with an interface to a set of Air Surface Detection sensors and to the Integrated Navigation System. The system can also download data from external sources such as satelllites and airborne radars.

The Integrated Navigation System combines data from global positioning systems, the log, depth measurement and the ship's trim/list monitoring system. The submarine's sensors also monitor the environment including seawater density and temperature as well as the submarine's own noise signature.


Weapons

The Tiger shark class boats excellent war fighting capability and an emphasis has been placed on land attack as well as anti-surface/anti-submarine warfare. The submarine has the capacity to carry up to 18 surface-to-surface missiles or torpedoes, which give the vessel excellent standoff capability.

The submarine has six bow torpedo tubes. Two of the tubes have a 650mm diameter which could provide the capability of launching swimmer delivery vehicles (SDVs) . With liners the tubes could be reduced to 533mm diameters Four tubes are 533mm diameter for launching torpedoes and missiles.

The submarine can also be armed with mines in lieu iof other weapons. A wet and dry compartment is installed for deploying underwater swimmers and special forces personnel.

Sensors

The submarine is equipped with the EMSS-055 integrated sonar system designed by Elias Marine Sensor Systems, a wholly owned subsidary of Elias Marine which has: cylindrical array for passive medium-frequency detection; a low-frequency towed array sonar; flank array sonar for low/medium-frequency detection; passive ranging sonar; and hostile sonar intercept system. There is also an active high-frequency mine detection sonar.

Propulsion

The propulsion system combines a conventional system consisting of a diesel generator with a lead acid battery, and an air-independent propulsion (AIP) system, used for silent slow cruising, with a fuel cell equipped with oxygen and hydrogen storage. The system consists of nine PEM (polymer electrolyte membrane) fuel cells, providing a total of 350 kilowatts.

For higher speeds, connection is made to the high-performance lead acid battery. A diesel engine powers the generator for charging the battery when either snorkeling or surfaced. The diesel generator plant is mounted on a swinging deck platform with double elastic mounts for noise and vibration isolation. The propeller motor is directly coupled to the seven-bladed variable pitch, low noise propeller.

Performance of the AIP system gives the submarine an underwater endurance of nearly 30 days which is unprecedented for a diesel electric submarine. This is a crucial advanatge because the need to come repeatedly to periscope depth to recharge the batteries using the diesel engine greatly increases vulnerability to detection.

Memorandum For: United Elias Dept of the Navy
From: Rear Admiral Archibald Longstreet, Agnostican Naval Procurement
Subject: Purchase of EM-220 vessels

We are interested in procuring fifteen of these vessels for coastal defense and are willing to pay via currency, barter of weapons or of resources, any and all of which are reasonable to us. We have been given a procurement budget of five billion for this project but are interested in the omission of and the changing of two systems.

1. We would like fourteen of the vessels to be delivered without the standard sensor suite. We have our own sensors that we would like to test against the system in place and determine which is superior. We would thus like the option of procuring the sensor system should our tests reveal the system in place to be the better of the two. If we could be given a price estimate on the vessels without the sensor array, we would appreciate it.

2. We would like all of the tubes configured for 533mm. As these are to be coastal defense and we already have a number of our own diesel electric missile boats, we ould simply like to use these as hunters. Unfortunately, missile launch is, perhaps the most obvious location marker for a submarine and we would want these to remain undetected for as long as possible. By using the wires on the torpedoes, we can effectively decoy a force. Thus we are not interested int he purchase of the EAW-22 or the Yakhont-3 although we know them both to be very reliable weapons systems.

As a point of order, we would like to offer a compromise should we find our sonar suite to be better than that of the native ship. For the equivalent price, we are willing to supply your vessels with our sensor package if it does indeed outperform the existing one. We would simply ask whatever price you have on the invididual submarine subsystem in this proposed joint venture. We are aware that this may be a bit arrogant but we are still extending the offer in the spirit of mutual defense and friendship.

Please let us know what your response to this message is as soon as humanly possible.

Memorandum of Understanding

To: Rear Admiral Archibald Longstreet, Agnostican Naval Procurement
From: Commodre Maurice Steinberg, Submarine Department, Ministry of Defence Procurement and Export
Subject: RE: Purchase of EM-220 vessels

Thank you for your interest in this type and after consulting with the Elias Marine Corporation (The prime contractor), we have allotted hull numbers 28-43 for the Agnostican Navy. First of all I must point out that because of high demand, construction will not be able to commence for at least two months and only two vessels can be built simultaneously. However since many of the components are pre manufactured and stocked at the shipyard, as further orders are almost certain, construction of each vessel should only take three to four months from the point of the hull being laid down followed by two to three weeks of sea trials.

The modifications you wish to make are possible and indeed we can use the two month delay to our advantage by making sure that your indigenous sensor system is in place and ready to be installed, this is assuming you would rather the system was installed during construction as this would be the simples and cheapest way to integrate it. On this subject we estimate the cost saving to be a total of 9.77 million and this inlcudes the cost of integrating the Agnostican sensor array.

If in fact both of our Navies agree that your system is superior we will negotiate costings thereafter. We do reccomend however that the tests are completed before the second batch of two is completed so that the correct system can be installed, saving the extesnove cost of retrofitting.

With regards to the request of changing the torpedo tubes we have calculated that because the sub systems are largely premanufactured, it would cost no less and more lilkely slightly more to make this modification as the bow of the submarine would have to be redesigned and new components specially made. We stress that the 650mm tubes can be used as 533mm tubes with the use of tube liners. A saving can be made if you choose, of some 1.15 million per unit if the missile fire control systems were not included but this removes completely the option of firing anti-ship or land attack missiles.

I hope this answers some of your questions and I look forward to coperating in this procurement effort.

Sincerely,

Commodre Maurice Steinberg,

Can I have 5?

I am a close allie of both Freedom Country and Kaazakhsthan, whom I believe are also your allies?

Excellent diesel boat, we'd order if we had the inclination to buy more subs (which we don't, we have more subs than we know what to do with).

As an aside, Pheonix Defense Industries makes some of the most, if not the most, advanced SSNs and SSBNs on the planet. Your nation is on the government approved list for the restricted submarines and you're eligible for a sizable discount because of the excellent products you have sold us in the past.

From: Rear Admiral Archibald Longstreet, Agnostican Department of Naval Procurement
Subject: EM-220 Submarines

Commodore Steinberg,

We would first like to extend our appreciation for accepting our order and state that the Agnostican Holy Navy is eager to test the new vessels. We would also like to announce our understanding that the soonest construction can begin is in two months. We understand the demands placed upon the shipbuilding industry of late and salute your efforts for expedient manufacture and delivery of said systems.

Upon the subject of the boats in question, it is still the desire of the Coastal Defense Force that these ships be fully manufactured as solely 533mm-tubed vessels. We understand that by adding in the liners it it possible to reduce the tube diameter however the CDF has specifically declared a missile-platform is unnecessary. Mainly due to the fact that the vessels can carry an increased weapons load with the missile racks removed, this is understandable. Seeing as no EM-220 will be without our own diesel-electric attack subs, the requirement for a missile platform, they concluded, was undesirable.

On to the AE-56B Cortex sensor suite. We will deliver one full system with all part as well as a back-up for installation in hull #29, #28 being the one designated for inclusion of the original sensor suite. We would ask that production on the other 13 vessels be delayed until both #28 and #29 have run their sea trials against each other in a matched competition. We sustpect that elements of the native system are going to outperform those of the system we have introduced, however that is why we would also like to send a team of four of our own electronic engineers to aid in the mating of your boat and our sensors.

As one word of note, the Cortex will require a slight hull modification along the conning tower and the equator of the hull. The pulse array, failsafe targeting sensors and emitters will need to be made flush with the surface.

Should there be any further questions, I would ask that you direct them, as you have already, to my office.

May this be a long and profitable relationship.

Greetings, United Elias.

Could I order 10 for the total cost of $2'950'000'000

If we sent some computer equipment over would you be able to install it.

It is the computers we need to allow our navy to control our offshore Sea-RAM anti-ship missiles.

Yes, that is indeed accpetbale, order confirmed. Extra installation will cost $120,000.

Thank you very much, we will send the computers by air. Please lower air defences if any are online.

Credonia would like to buy 10 of these submarines.

I wish to have this implemented to cut back on the amount of firarms moving around. Tons of weapons mean itchy trigger fingers. Nations should have no more weapons than they need. All the surplus should be destroyed.


Nowhere does it say that I want to eliminate war forever.

yes, but still, "all the surplus should be destroyed?" i don't think so. If this law is passed, i just simply won't obey it.

Agnostican Holy Navy,

The Elias Marine Corporation is proud to inform you that both hulls 28 and 29 are complete and have now been launched. Currently some preliminary inspections are underway to check the state of the vessels and they are alongside at Abdullah Naval Yard pending the arrival of your evaluation team. We convey our apologies for the delays in construction but integrating the AE-56B Sensory array proved quite troublesome given the modifications to the hull which required several design attempts. The submarines have been completed, as requested with only 533mm torpedo tubes although no cost savings were made due to the reasons described hitherto. However contrary to our original estimate, this minor change was delivered at no greater cost than what it would have been if the design was built to standard specification.

We have now reached the stage where ship yard space is being allotted for the subsequent hulls and therefore we hope that the sensor tests can be conducted with some degree of rapidity, both to ensure a timely delivery of the follow on submarines and also to free up our construction facilities for other orders. After the evaluations have taken place we will also begin to retrofit whichever of the first hulls has the least capable sensory system and replace with the superior one, whether it be the AE-56B or our indigenous system.

For The attention of: Commodore Maurice Steinberg, Submarine Department, Ministry of Defence Procurement and Export
Federal Dictatorship of United Elias

The Commonwealth Federation of Rhodesia and Nysaland takes great interest in the Tigershark class submarine which is offered for export by your nation. However, Rhodesia has no standing navy of such, just the Rhodesian Maritime Service (RMS) which is more of a coat guard/patrol force.

Therefore any procurement we make must also includes, complete training in United Elias for operating and maintaining the vessels. Also we require a contract to provide spare parts and repair any critical damage as well as undertake rescue missions in the event of our submarine being stranded on the seabed.

Currently, the budget for this part of 'Project Deepwater' is severly limited at only R£985 million (equivalent to UK £) which includes the total costs involved in putting the vessles into service as well as one year's operating costs. The RMS is aiming for an in service date for the initial unit within three years of contract agreement.

Now that you know how much we are able to spend and what services we require, I shall leave it in your capable hands to find a package that delivers value for money, efficiency and rapidity.

Yours Sincerely,
Sir Robert Cotterell
Minister for the Defence of the Realm
Commonwealth Federation of Rhodesia and Nyasaland
