[Pepperbox class Logistical Support Vessel [LSV]]
http://www.naval-technology.com/projects/patino/images/Patino_1.jpg
[Abstract]
The Pepperbox class LSV is the Empire's sole logistical support vessel and has been the workhorse of the new Kriegsmarine since the accension of Jonach as Emperor of the Golden Throne.
The purpose of the Pepperbox class LSV is to fully support the long-range missions of a naval squadron, which would typically include an aircraft carrier and complete escort. The logistic support vessel has to be in position to refuel the squadron, including the air wing of the carrier, and also provide full logistic support in terms of repair workshops, spare parts, ammunition replenishment and supplies.
Pepperbox class LSV is also capable of performing civil protection roles at times of crisis. The ship has high autonomous capacity to provide electrical power, fresh water and prepared meals and also has fully equipped hospital and medical facilities on board.
The ship is available in optional configurations to: house, feed, transport and deploy troops; deploy and retrieve helicopters and patrol boats concealed below the flight deck; train military personnel in seamanship; partially submerge allowing at-sea loading and unloading of smaller vessels; and civil/military inter-island transportation
[Weapon Systems]
The Pepperbox class LSV has two of the brand new Conhort Close-in Weapons Systems. The Conhort uses a variant of the GAU-8 Avenger cannon. The GAU-8 itself weighs 281 kg (620 lb), but the complete weapon, with feed system and drum, weighs 4,029 lb (1,830 kg) with a maximum ammunition load. The entire system is 19 ft 10.5 in (5.05 m) long. The magazine can hold 1,350 rounds, although 1,174 is the more normal load-out. Muzzle velocity with armor-piercing incendiary (API) ammunition is 3,250 ft/s (988 m/s), almost the same as the substantially lighter M61 Vulcan.
The Conhort's system consists of an autocannon and an advanced radar which tracks incoming fire, determines its trajectory, then aims the gun and fires in a matter of seconds. The system is fully automatic, needing no human input once activated. The kinetic energy of the 30mm rounds is sufficient to destroy any missile or shell. The system can also be deployed to protect airfields. However, like the Dutch Goalkeeper and the American Phalanx the Conhort is a last-chance weapon, although considerably accurate. It uses a seperate, smaller, LIDAR Gaussian Transmitter and RADAR tranmitter in order to lock on potential targets and blow them out of the air. Several advantages the Cohort has over the Phalanx system are that it is more accurate, it has a greater kenitic energy impact, more tracking, it's reloaded under the deck, and it can operate under three modes: Auto, Semi-Auto and Manual allowing full operator operability.
For underwater defenses the Indestructable has four ASHUM guns, which basically work as underwater close-in weapon systems. The magazines can hold 1,200 rounds and they're reloaded in compartments placed above the guns. The ASHUM guns placed on the Indestructable are trained through the ship's SONAR, as well as blue-green Guassian LIDAR transmitters placed for the individual guns.
[Sensors and Countermeasures]
The Pepperbox class LSV is fitted with a single broadband surface search RADAR, but relies on its single Sea Serpent II Multi-mission Helicopter for most of its electronics operations.
The countermeasures suite includes: four Mk 36 SRBOC (Super Rapid Blooming Offboard Chaff) six-barrelled launchers from Sippican Hycor which fire infrared decoys and chaff for confusion, distraction and seduction of incoming anti-ship missiles to a range of 4km; an AN/SLQ-25A Nixie towed torpedo decoy system from Sensytech Inc of Fedala, Second Empire of the Golden Throne which has two towed units that emit acoustic signals from an onboard transmitter; and an Aldebaran electronic support measures/electronic countermeasures (ESM/ECM) system supplied by the Empire's Indra Group.
[Cargo System]
The prime mission of the ship is the direct transport and discharge of liquid and dry cargo to shallow terminal areas, to remote under-developed coastlines and on inland waterways. The ships also provide a drive-through capability by mating the bow ramp to the neighbouring stern ramp in order to form a floating bridge. The ships can be computer linked to logistics files at military stock points, and can transport roll-on/roll-off and containerised cargo for unit deployment and relocation, tactical resupply and sustained resupply.
The ship does not require external cranes or port facilities and four feet of water allows the ship to land under full load. This capability expands the choice of landing locations and reduces the potential enemy impact on the logistics support operations. The ship also provides self-delivery to overseas locations. The ramps and the main deck are able to withstand roll-on/roll-off operations of the Pzkmf. XI, the P&H 6250 crane complete with counterweight and boom, and rough terrain handlers.
The ship can carry up to 900 short tonnes during Logistics Over The Shore Operations (LOTS) and up to 2,000 short tonnes during Intra-Theatre Line-Haul (ITLH).
[Helicopter Capabilities]
The LSV-Helicopter Capable configuration provides concealed transport, deployment and retrieval of both helicopters and patrol boats. Seap Serpent II helicopters are concealed below a modular flight deck while patrol boats and intercept craft are behind the stern ramp. The configuration presents the appearance of a logistic supply ship without the obvious display of force.
[EMP Hardening]
There are two things to consider when considering hardening targets against EMP. The first question to answer is whether the hardened system will become useless if shielded. The second question to be answered is whether the target is economically worthwhile to harden. The answers to these two questions are used to determine what devices should be shielded
To explain the first consideration, Makoff and Tsipis give the following simple example. If there was a communication plane with many antennas used to collect and transfer data, it would not be useful if its antennas were removed. However, to harden the plane, the antennas would need to be removed because they provide a direct path to the interior of the plane.(18) It is important to understand how the hardening will affect the performance of the hardened item.
The second consideration is very easy to understand. Some systems, although important, may not seem worthwhile enough to harden due to the high costs of shielding. "It may cost from 30% to 50% of the cost of a ground based communication center…just to refit it to withstand EMP," and, "as high as 10% of the cost for each plane."(19)
There are two basic ways to harden items against EMP effects.20 The first method is metallic shielding. The alternative is tailored hardening. Both methods will be briefly described.
Metallic shielding is used to, "Exclude energy propagated through fields in space."(21) Shields are made of a continuous piece of some metal such as steel or copper. A metal enclosure generally does not fully shield the interior because of the small holes that are likely to exist. Therefore, this type of shielding often contains additional elements to create the barrier. Commonly, only a fraction of a millimeter (22) of a metal is needed to supply adequate protection. This shield must completely surround the item to be shielded. A tight box must be formed to create the shield. The cost of such shielding (in1986 dollars) is $1000 per square meter for a welded-steel shield after installation.(23)
The alternative method, tailored hardening, is a more cost-effective way of hardening. In this method, only the most vulnerable elements and circuits are redesigned to be more rugged. The more rugged elements will be able to withstand much higher currents. However, a committee of the National Academy of Sciences is skeptical of this method due to unpredictable failures in testing.(24) Also, the use of this method is not recommended by the National Research Council. They doubted whether the approximations made to evaluate susceptibilities of the components were accurate. They did concede that tailored hardening may be useful to make existing systems less vulnerable.(25)
[Propulsion]
The ship is powered by two Zonoras 12 V ZA40S diesel engines with a maximum continuous rating of 8640kW at 510rpm. There are two reduction gears with pitch actuators, driving two independent shafts with controllable pitch propellers. The ship also has a bow thruster. The propulsion system provides Pepperbox class LSV with a continuous speed of 21 knots at full load displacement. The range at an economical speed of 18 knots is 7,600 nautical miles.
Power generation is provided by two shaft generators each rated at 1000kW and four diesel generators each rated at 780kW.
[Cost]
The Pepperbox class LSV costs 200 Million per ship.
