OOC NOTES: The different vessels of this class will often have different superstructures, masts, net configurations, etc so that identifying them will be difficult.

Many of the vessels will be "owned" by off shore corporations and foreign flagged. These vessels probably violate some sort of law, but the possible eventual political ramifications is all part of the fun of RPing.




Kalev כלב class Sonar Surveillance Vessel (STV)

(Why bother finding a hiding place when you can hide right in front of their eyes?)

http://i11.photobucket.com/albums/a178/chicagobears777/surtass.jpg

Project Overview:

The כלב (Kalev class) was begun as Israeli Naval Officers expressed a desire to have an ASW surveillance platform that could hide in plain sight. The Kalev is a vessel that is designed to resemble a standard commercial trawler. Instead of fishing nets, it is outfitted with towed SONAR arrays and high tech communications gear. Upon launch, the Kalev bears the paint of a warship, but she will be repainted in civilian colors and will be outfitted with standard equipment for a stern trawler to enhance her cover.

The Hel HaYam's design board noted that modern submarines are nearly impossible to detect from maritime patrol aircraft. Maritime patrol aircraft are still useful as they can quickly bring an ASW payload to a battle zone faster than surface ships or submarines. They also are immune from attack when facing most enemy submarines. The problem is that a surface ship is needed to vector in the ASW aircraft. This vessel will fulfill that role while remaing safe from attack. The vessel will be difficult to spot in the first place as it has such a small size. Should the vessel be seen, it will look like, sound like, and act like one of the thousands of fishing trawlers prowling the oceans. The vessel will often not even have the flag of HaMedinat Yisrael on it. Crew members will not wear Naval uniforms. They will wear the gear of civilian commercial fishermen. The vessel will have a complete array of trawling gear and nets. the vessel will carry out trawling operations, but this is all part of the disguise.

MENACHEM BEGIN Class Gun-Cruiser Mod 2

http://i11.photobucket.com/albums/a178/chicagobears777/BCA.jpg

SPECIFICATIONS FOR ISS MENACHEM BEGIN, CA-24

LENTH: 784.5 feet long
BEAM: 136 feet (trimarian hull)
DRAFT: 31.5 feet
DISPLACEMENT: 75,500 tons
POWERPLANT: 2 IEA LW5 Reactors at 74 MW each (148 total)
PROPULSION: 4 reversible pitch screws
MANEUVERING: 2 x rudders aft, 2 bow and 2 aft thrusters
SPEED: 32 knots max sustained speed, can burst to 34 knots


ARMAMENTS:
9 x 10” 55 cal. IDF MK-114 Rapid Fire semi-automatic ETC Cannons (3 triple turrets). These guns were specially designed for this ship and actually the ship was designed to carry these guns. The guns have a range of 80 km, about 20-25% less than the range of comparable cannons, but that is so the guns can have their strength. The guns were made for massive fire power to be delivered quickly. IDF Engineers took the guns from The Des Moines class CA's and worked to improve her guns and their rate of fire of 10 rounds per minute per barrel. During tests, the guns fired about 15 times per minute per barrel or 135 x 10” shells in a single minute! These guns are superior when it comes to shore bombardments. Imagine being able to put 135 shells on a beach in 1 minute when you are trying to clear the beach for an invasion team. Or imagine a duel between 2 cruisers. Who will win if you have a much better firing rate than the enemy? The guns can be elevated to 42 degrees, giving them AA capabilities. The only disadvantage of the fast firing rate is that you will eventually run out of ammo and overheating can be a problem, but your target will probably be dead by that time.

15 x 5” 42 cal MK-102 ETC (15 single mounts)semi-automatic cannons, range of 55 km. These guns can fire about 30 times a minute so that equals 450 shells fired per minute from the ship. This adds to the quick fire power of the main cannons. These guns are also good for the killing of shore targets or other ships at closer ranges. They are very good if you want to clear an area of enemy troops.

12 x 8 (96 cell) VLS system aft of superstructure. This system is better if you want to defend yourself with SAMs or if you want to attack at longer ranges than your guns allow.

The Mod 1 replaced the original CIWS system with the Mk-1 Mod-0 Integrated Point Defense System developed for the Yerushalayim class super dreadnoughts. After several successful tests, it was decided to put it on this vessel. Four of the pods have been placed on the vessel. Each one is at a corner of the superstructure.

SURVIVABILITY
10" Belt,
10.5" Turrets,
6" Deck,
8" Superstructure

The armor is made up of the steel hull, Kevlar to deflect fragments, tubes running through the interior of the hull to help absorb and break up the explosive force of a weapon impact. Fire proof coating is placed all around the interior and exterior of the ship.
The most important part of the ship’s survivability is the use of the Advanced Fire Control System developed for the Yerushalayim class dreadnoughts. This is the biggest difference between this vessel and previous versions. Fire is the greatest threat to a ship in combat and we give our sailors the best chance to deal with it.

STEALTH
The ship wasn't built to be a stealth ship as her primary ability as the Meir was, but she adopts the Meir's innovative designs. Most notable is the superstructure design, jokingly called the F-117 design. This reflects RADAR waves and reduces the RCS. The trimarian hull also helps give her stealth. Another note worthy stealth innovation is the fact that most of the decks, especially the well decks, are angled to give a smaller RCS. On top of this, the hull is coated with a rubberized RADAR absorbing material. This material also extends hull life and combats corrosion.

RADAR/LADAR
This vessel is the first to carry the IDI Caleb I Mod 1 integrated RADAR system. It is an improvement of the RADAR system used over the past 5 years on new ships.

AIRCRAFT
No hangar facities or shelters, but the ship can land 1 SH-60 Seahawk or equivalent chopper.

Israeli Military Industries Shipboard Fire-Fighting System.

The initial hit from a weapon is not what is going to sink your ship. The after effects of flooding and fire are more likely to destroy your vessel. Of these threats, fire has led to more ships being lost in battle than flooding. As you walk through passageways and compartments, you will notice several pipes running along the bulkheads or hanging from the overhead. Every single compartment and passageway has several three-way gaskets. These pipes are part of the advanced fire suppression system.

Each compartment has at least two sets of 4 pipes. Within the four pipes are water, CO2, Dry NaCl granules, and AFFF. The pipe gaskets are controlled from the bridge, Auxiliary machinery Rooms, the Engine Room, and DC Central. Those sites can control all gaskets aboard the ship. Localized DC Lockers can control the gaskets for nearby compartments. The use of multiple sets of pipes ensures that breaches won’t compromise the entire system. Pressure can be cut off if necessary when a pipe bursts.

Extra pipes are present in critical areas of ships like magazines and turret lobbies. This is crucial as these sections may require emergency flooding of water, or one of the chemicals used by the ship. It has happened in past battles where flash fires in these areas destroyed an entire ship. The quick ability to flood the compartments can suppress these flash fires before they compromise the ship.

The key to the fire suppression system is an array of sensors which inform DC crews, engineers, and the bridge what damage has occurred and where it is. They also can detect which type of fire is burning. This allows the operators of the fire suppression system to know which system to use to extinguish the fire. This is important as the crew needs to know whether a fire is Class A, B, C, or D. Use of water on class B,C, or D fires can make matters worse and only NaCl granules can deal with a dreaded class delta fire.

In order to ensure the system works when main power fails, auxiliary generator units or battery power on vessels fitted with such systems can be used to power the systems.

פרס (Peres) Class Patrol Frigate

http://i11.photobucket.com/albums/a178/chicagobears777/PFM-1-1.png

Executive Summary

While the Israeli Naval Yards has been building many larger vessels in recent years, corvette designs have not been approved. Chief of Naval Operations, Fleet Admiral Joseph Jacobson has addressed this issue in his 05-06 State of the Navy Report. He called on the design bureaus in Israel to come up with new designs for corvettes. INY, Israeli Military Industries, and Kineret Defense each came up with competing designs. INY won the contract, but adapted the design to incorporate some of the better systems conceived by the competing designs. The final design of the vessel was 3,175 tons. This made it too large to classify as a corvette. As a result, the vessel was rebranded a patrol frigate.

The Peres was built to fill a void of vessels that can patrol and protect Israel's coast. The vessels are capable of going out on the open ocean and dealing with foreign threats, but that was not the focus of the design board in creating the class. The vessel is the first to mount Israeli Aerospace Industries' Second Generation upgrade of IDIs Mk-1 Mod-0 Integrated Point Defense System.

The export version of this vessel is unable to carry the larger near-hypersonic SSMs, but it can mount the upgraded version of the venerable Gabriel SSM. Domestic versions mount S-14 launchers in place of the standard S-12 launchers. The S-14 allows this vessel to carry four of the USM-8 Jericho Hypsersonic anti-ship missiles. The 24 cell VLS system can carry any arrangement of SAMs or ASW Missiles. In order to save costs, torpedo tubes were not included.

A few minor drawbacks of the vessel are the lack of tubes. The patrol frigate also cannot land a helicopter, but the use of land based maritime patrol aircraft and helicopters makes up for this problem. A third and final flaw is the fact that the point defense fails to cover 45 degrees to either side of the bow. The ship will just have to maneuver appropriately to use its dual point defense systems.

Reuven (12 Tribes Class) CVN

http://i11.photobucket.com/albums/a178/chicagobears777/SCVN-1.jpg

Project Overview:
For many years, IDF had operated a fleet of supercarriers that could carry 200 aircraft. In the years since HaMedinat Yisrael was reorganized as the second state in the ashes of the defeated IDF, no new carrier designs had been developed. Fleet Admiral Joseph Jacobson presented a proposal to the Knesset to form a design team to look into the development of a new class of aircraft carriers to carry The Hel HaYam into the future.

The design team was formed and looked at what the future needs of a carrier were. A monohulled CVN with a maximum flight deck beam of less than 300 cannot operate more than 100 fixed wing aircraft. It was for this reason that IDF had built the large trimaran CVNs. The exploratory committee looked at this idea and decided not to rehash it. While the trimarans could operate 200 fixed wing aircraft, they also were at least 5 times heavier than their monohulled counterparts, and they are just as easily mission killed when in battle. Efficiency of displacement was only 40% of that of a monohulled carrier.

Clearly, this was unacceptable for any future carriers. It was deemed that having more monohulled carriers would be more efficient, and simply a better strategy than having more aircraft on fewer, larger carriers. The new Reuven class CVNs were to be the future of monohulled supercarriers in the Hel HaYam.

The design board did decide that this new carrier had to be larger than any current monohulled carriers in the fleet. While the carrier would only have 110 total aircraft (92 fixed wing, 8 tilt rotar, and 10 rotary) it would still be 30% larger than current designs in the Hel HaYam’s fleet. This was important as the new carrier would be designed to carry larger aircraft that are currently being designed to enhance the strike capabilities of carriers.

While the total number of aircraft cannot be increased, the carriers can be designed to carry larger aircraft with increased range and payload capacities. The larger carrier also allows for a higher hangar clearance and just more general storage space for these new naval aircraft. When the carrier operates with current generation aircraft or stores aircraft on the deck, it will be able to carry a significant load of UAVs.

Waterline: 150 feet waterline
Max Width: 275 feet
Draft: 42 feet

Propulsion and Power

Israeli Naval Yard’s (INY) Propulsion Department has once again collaborated with Dimona Nuclear Technologies to develop a reactor plant for the Hel HaYam. The powerplant in question has been named the INY/DNT-2A. Its output is rated at 80 MW.

Four of the large reactors have been installed aboard the 12 Tribes Class vessels producing a total of 240 MW of power. The steam from the reactor plants provides both power for the screws and for the electric generators.

The vessel is propelled by four shrouded screws. The screws can propel the vessel to a maximum speed of 32 knots. The vessel’s standard cruising speed is 30.5 knots. She can maintain this speed for a long duration and only needs to be refueled every 20 years.

Damage Control

As this vessel exceeds 2,500 tons, it will be required to carry the Israeli Military Industries Shipboard Fire-Fighting System. The system has been modified for specific use on a carrier. Dozens of extra pumps have been added to the vessel and the vessel has unusually large fluid storage tanks, even for a vessel of her size. This has been done as aircraft carriers are more susceptible to fire due to the large amounts of jet fuel and ordnance onboard the vessel. The hangar deck also is a major danger zone in the event of a fire.

The large open space of the hangar deck presents many problems in the event of a fire. It is for this reason that the hangar deck will have eight sliding fireproof doors that can be closed in the event of fire. Each door can be closed by an electric motor in as little as 15 seconds. If the motors are damaged, they can be manually closed by as few as thirty men. The doors have been positioned to close along a track which must not be obstructed by aircraft or ordnance.

Once the doors are closed, the section in question can be closed off from other portions of the ship. The automatic fire-fighting system will be more effectively utilized in a compartment like the hangar space when it has been subdivided into smaller compartments in case of an emergency. A major flight deck fire or hangar fire may be too much for the automatic system, but crews will have an easier time responding to a fire when it has already been smothered with AFFF, water, CO2, or Copper powder. It takes as little as 150 seconds for a bomb to cook off. This system will give the crew enough time to douse bombs with the appropriate compound or chemical agent and ensure that the vessel is safe from her own munitions.

Extra nozzles and distribution points for the automatic system have also been added to the vessel’s magazines. The magazines can be completely flooded with the necessary agents in less than 2 minutes.

When fighting fires, water or other fluids can often settle on one side of a vessel inducing a list. Flooding of a vessel can also induce dangerous lists. The vessel’s fuel tanks, water tanks, and of course the tanks for the fire-fighting system are all subdivided into central, port, and starboard tanks. Pumps will allow officers in Damage Control stations, engineering spaces, the bridge, or CIC to take action to ensure proper balance of the vessel.

Crew

Improvements in automation technology have allowed for smaller crew sizes. The vessel’s company will comprise of 150 officers and 2150 enlisted men. About ¼ of the enlisted men who are part of ship’s company will be rated as CPO or higher.

The automation unfortunately doesn’t allow for smaller air wing crews as aircraft still require heavy maintenance. The size of air wing crews will vary as different aircraft are used on carriers, but the expected size of the crew will be 2,600 personnel.

SONAR:

IDC SFS-8 Hull mounted flank SONAR

The vessel is also equipped with a large EW fleet. 104 of the ship’s company are rated as EWs. The EW crews and their equipment are vital to protecting the vessel from attack. They specialize in jamming missiles and helping delay the launch of hostile weapons. A good EW crew can delay an enemy launch by as much as 2 minutes. That time gives the air wing’s interceptors additional opportunities to engage hostile threats. Israel’s experience in the Battle of Latakia has demonstrated the importance of Electronic Warfare.

Weapons

2 x CVMRAA SPYDER launchers with 48 missiles per unit.

8 x IAI/IDI Second Generation Mk-2 Integrated Point Defense System (comprises of)
IAI NSA 3 Box launcher with 45 SAA-4 Point Defense Missiles (reloads available)
IDI NAA 30 mm autocannon with 4,500 rounds

Aircraft launching and arresting systems

Four EMALS catapults will be used on the vessel. The larger deck space allows for the catapult tracks to be lengthened. This will help with the launching of larger aircraft from the carrier.

EARS will be implemented as the primary aircraft recovery system. Of course crash nets will be included on the carriers for emergency situations.
