- * - * - so it has come to our attention that you are interested in mudskippers - * - * -
Cutting the land with millions of wide and narrow rivers, water offers the only mode of transportation in Vault 10 territory, apart from flight. With efficient transport routes comes the danger, and, being much harder to control than airspace, the Vault 10 river network is a true blessing for all criminals.
With more and more advanced technologies in the hands of crime, Aerospace Logistics Corporation has to always be ahead in the race. The latest addition to the internal fleet, Mudskipper class hydroplane, integrates the latest of naval technologies with efficient aerospace-based design, to secure advantage in the internal and littoral waters, while being able to keep up with blue water navies as well.
The primary materials in hull structure are carbon fiber reinforced polymer composites. An exception to that is the lowest part of the bottom, which experiences heavy slamming in high sea states, and possibly heavy hits with underwater rocks or the surface on small waterfalls, so is constructed of highly durable alloy to avoid the risk of cracking.
Hull sides and top are built with a polycomposite material, consisting of high-strength polymer matrix, carbon fiber reinforcement, and small metal, ceramic and fullerene particles. Apart from necessary strength, this structure provides radar waves absorption at certain frequencies, and, around the cabin, projectile-eroding protection against small arms.
While in general the size of the vessel precludes efficient damage control, automated fire suppression systems and compartmentalization allow the Mudkip to resist most attacks. Low-flammability materials and decoupled structure contribute to this capability. The chance to survive a hit by heavy missile (100kg+ explosive) is less than 20%, but the chances considerably higher against light missiles, reaching 60% against a 50kg warhead and 95% against a 20kg warhead. Due to dynamic support, the vessel is efficiently immune to torpedo explosions, except for ones occurring in the immediate vicinity. The placement of modules at the sides serves as a form of armor, absorbing missile hits and preventing damage to the fuel tank.
Since the hull structure already provides all required stiffness, the hull plating is manufactured as a solid flexible sheet, rather than sandwich panels, thus avoiding the characteristic reflective grooves between them.
Four factors contribute to over an order of magnitude lower observability compared to semi-stealthy vessels: tumblehome shape as opposed to compromise seen on Visby; lack of protruding parts and absolutely any inward angles; structurally embedded radar absorption; and, finally, extremely low profile, measuring less than 5 meters above the water.
Side and top views.
Extreme speed of the hydroplane requires appropriate protection against slamming, provided by alloy double bottom and flexible vibration-absorbing mounts for all equipment, including the pumpjets. Apart from allowing for high-speed travel, abrasion-resistant bottom, high engine power, and controlled lifting force let Mudkip to pass with minimal issues through any river which is at least 1m deep within 6m and at least 16m wide overall. Shallower or slightly narrower passages can only be passed at low speed and with extreme care.
In compliance with the VTS-105 Addendum 3, ratified in Vault 10 in February 2005 and canceling the military exceptions to the fossil fuel restrictions, the Mudskipper class operates on hydrogen-based fuel. The vessel can use either standard medium purity hydrogen, derived by electrolysis using geothermal and nuclear power, or HCH90 fuel mixture, consisting 90% of hydrogen and 10% of methane produced by capture of carbon dioxide and synthesis with hydrogen. The tank is divided into 8 full-pressure compartments, and surrounded by damage protection zone, which ensures that in case of hit, only one compartment is compromised.
The fuel is turned to motion by one of the two options. Respectable and trustworthy partners may order two Symmetriad Linus-IV turbines, which provide up to 5000kW of power and 55% efficiency within 60%-80% range, and Symmetriad Camilla-II composite flow pumpjets with 90% efficiency at full power. In case this equipment is not available to the particular customer, or the cost of Symmetriad equipment seems excessive to him, the vessel can be equipment with industry standard NCR Heavy Industries MTH-4000, 4000kW turbines with 45% efficiency at 70%-80% load, and MJS-E6 75% efficiency axial flow waterjets.
When loaded with the full load of sixteen tonnes of HCH90, the high energy density of the fuel allows the turbines to run at full power for 28 hours. At 60% power, the turbines can work on one load for 60 hours, providing the vessel with Symmetriad powerplant with over nine thousand kilometers of range in river or littoral environment.
The basic hull of Mudskipper carries no armament at all. Instead, sixteen "units" are provided for the installation of modular equipment. Standard 1U module measures 2.00m in length, 2.78 in width and 4.45 in height. Out of these, 0.2m in height is taken by vibration absorbers, and further 0.1m left reserved. The nominal unit size is, therefore, 2.0x2.75x4.0, leaving certain headroom.
The weight per unit is restricted to 4t maximum, and no more than 2.5t average, with 40t limit for all modules. Nominal expected unit mass is 2000kg. Appropriate modules can be designed and built by the manufacturer or by the customer.
Modules can be, and usually are double-sized, 4.0x2.75x4.0m. Quad-sized and full-sized modules (8U) are also possible, at a compromise in compartmentalization.
Examples of armament that can be installed into a module include:
- 24x MLSA-10 MANPADS in VLS, with a dedicated IRST system
- 6x any SAM up to 150kg in weight, with a dedicated IRST system
- 1x open manned dual M2HB .50BMG machinegun mount, retractable

High-speed crashes have been the second most common KtB cause in the ALC Riverine Fleet for a long time. Only 15 years ago the solution was found: PAML, Pilot Analysis Mini-Laboratory, which proved to be among the greatest mankind's inventions, saving thousands of lives and boats yearly. Being even more dangerous due to its speed capabilities and firepower, the Mudskipper follows up on the trend, introducing Advanced PAML, enhanced with last-generation medical technologies.
To allow the vessel to accelerate above the "low cruise" speed setting, the pilot has to breathe into a vent in the control console. Upon receiving the gas mixture, APAML conducts a rapid chemical analysis, verifying it to be actual fresh breath and indicate no more than 0.1% of blood ethanol level. The 35m/s (68 knots) in open water or 25m/s (48 knots) in riverine environment safe stop limit can only be exceeded with less than 0.06% alcohol in blood. The system is also capable of detecting a multitude of other recreational drugs, setting alcohol equivalent for each. Apart from regular check, a separate sensor constantly monitors alcohol level on the command deck using bleed air from the ventilation system.
Multiple systems are linked to assist in pilot condition analysis. The main computer's retinal scanner transfers the received data to the APAML for detection of unusual pupil behavior. All internal surveillance cameras conduct image recognition for detection of alcohol/drugs consumption, fornication, and explicit unsteady behavior. The automated mini-medlab blood analysis system, mainly designed for poison and infection control, is capable of detecting alcohol and recreational chemicals as well, and its use can be demanded by the APAML if there's uncertainty about crew condition. Finally, all APAML sensors are integrated with the shipboard NBC protection system sensors. All the data are analyzed to weigh the decision about pilot's suitability to control the high-speed hydroplane.
In all cases where the alcohol level exceeds 0.03%, the collision protection system is automatically activated and can't be overridden locally. As soon as predicted collision risk becomes considerable, speed is dropped and steering used to avoid it, regardless of pilot actions.
On most of Aerospace Logistics vessels the company policy also makes mandatory the installation of complete compact medlab. Taking one half-height unit of space (7 square meters) it allows not only for semi-automated treatment of the crew members, but also for more thorough analysis. The medlab incorporates Special Weapons Control Panel, to use which at least 2 crew members should be confirmed to have no more than 0.02% blood alcohol content or equivalent drug content. Once this is proven, the control panel becomes accessible, allowing activation of nuclear-tipped missiles and torpedoes. If the crew's alcohol or drug intoxication level is higher, nuclear weapons can only be activated if authorized remotely by a commander or higher ranked officer.
Being a small vessel, Mudskipper has no weight for armor and no ways to entirely stop the projectiles. To give it a degree of protection, all equipment is placed in peripheral modules, which act as a form of spaced armor. Since the chance of being hit anywhere but the main hull section sides or upper-side part is small, most times the damage is limited to 1-2 modules.
While the vessel isn't supposed to continue full-scale operations after taking a major hit, the damage control system allows for emergency launch of remaining ammunition and crew evacuation in all reasonable damage cases in blue water combat, and often even getting the boat to a port or a rescue/salvage vessel. In riverine and littoral combat against boats and ground-launched munitions, the damage resistance is of far greater importance, giving Mudkip additional advantage when it comes to close fight. Low packing density plays a major role in this: while a tank-fired APFSDS would go through the hydroplane without even slowing down considerably, the energy delivered would also be small, and so the damage.
In such cases, damage tolerance matters, and the vessel is designed with it in mind. A particular point of vulnerability being the fuel tank, it had to undergo significant internal compartmentalization. The whole tank consists of the inner and outer pressure vessels, intertank space insulated by aerogel and compartmentalized with silica inserts. The tank is split by 4 full-pressure main transverse bulkheads, going through all hull, and 6 auxiliary within the inner tank - vertical, horizontal and 4 transverse, which can only take the pressure of fuel evaporation within 1-4 hours depending on damage severity. They rely on the fuel system to clean them from bleed hydrogen: each of the 32 tank compartments has a separate valve, and, as soon as one is damaged, the fuel system nearly closes all valves in intact compartments and drains only the damaged cell(s).
Having the highest heat capacity of all substances, hydrogen in one cell absorbs over 100MJ of heat in evaporation and further over 1600MJ in heat exchange - enough to freeze the entire vessel well below zero Celsius. Due to internal insulation, it only freezes the leak-suffering compartment and making any ignition highly improbable. To use that further, as soon as leak is detected, the fire extinguishing system completely seals off the compartment and starts to supply it with nitrogen, displacing air outside. Water valves are opened to spraying, to cover both the damaged fuel cell and possible spark sources with ice. If the severity of the leak makes it necessary, hydrogen can be quickly drained from the damaged compartment and dumped overboard.
For the cases where damage tolerance matters, fuel tank self-sealing system can be installed, consisting of two parts: conventional self-sealing elastic layer within the outer cylinder, and capillary fabric with thin pipes, carrying water and covered with a special composition. Once the fabric is torn and some pipes are damaged, the water pours out in the damaged zone and floods both the section of intertank zone and outer part. Evaporation of liquid hydrogen solidifies it, forming a patch of stiff fiber-reinforced ice, a sort of carbon fiber based pykrite, based over the elastomer layer and remains of the tank structure itself. This protection level is capable of closing even significant hits as long as they don't break the tank. Installation of the self-sealing system incurs weight increase of 2500kg.
For further crew safety, the vessel's control room is equipped with zero-zero ejection seats, which can eject a crew member in a fraction of a second. If the shipboard radar and computer predict overall missile hit probability above 75%, or crew-injuring hit probability over 10%, the occupied seats fire off automatically in sufficient time before the hit. While also capable of working against collisions, this system is set not to react to them, apart from wartime, to prevent boat losses from reckless piloting.

An update of the project. Most modules still in development yet. But I've talked to a couple of guys from DARPA and learned how to squeeze out a little more out of it.
First of all, I've earlier accounted for 1980s carbon fiber reinforced plastic. A good improvement was done since then. Saved a few tonnes, but I didn't lighten the Mudskipper, though - I just don't like the hull to be too light, it's bad in certain aspects. Instead, I've increased its size, so now there's more of it to liek.
Fuel tank got tensile domes on the ends, which are lighter and stronger, though take some of the space gain.
Improved compartmentalization and added aft protective space for the fuel tank. Increased its size to give more power to the new waterjets and turbines, the latter moved to the bow compartment.
Installed larger, more efficient and quieter waterjets, in the aft section. Instead of directly turbine-driven waterjets, they are now rim-driven electric.
Pump sections are based on Rolls-Royce Kamewa S-71 and partially AWJ-21. Kept them a bit larger, but at reduced weight, as: 1) they don't have the complex 90-degree 3D thrust vectoring like the Rolls-Royce ones; 2) lighter materials are used - S-series are for big ships and so made of steel, while this is already a CFRP boat, so it's OK with light alloys and carbon fiber. Simple 30-degree 2D vectoring is retained. Increased power of new jets allows for increase in top speed from 68 to 75m/s, although other speeds are subject to hull and wave limitations.
Module size increased. There's less free space left, though, so the modules might use some of their space for communications if they're not OK with the standard package of electricity, water, steam, pressurized air.
Not only that, but there are more modules now. 18 instead of 16. Note that these extra two are supposed to give you more choice in crew housing and aux equipment, not pack in more guns.
New feature - there's the central drain pipe going right to waterjet intake, so they can pump the water out of any compartment, eliminating the need for separate drain pumps. And they can do it very fast - one fully flooded module can be drained in 8 seconds. Conversely, the firefighting system takes about the same time to fully flood a module. The effect on stability is better not mentioned, but on the other hand counterflooding can be near-instant, and the boat can sail full of holes as long as there's fuel for the jets. Technically, in planing mode it barely touches the water, so could anyway, but now it's more reliable.
The drunk bastard Seaman Mitchell thrown overboard. Don't worry, he won't drown, since it's still in the dry dock.
Finally put the characteristic fin on top - the radar. Now, a challenge to all you Mudkip liekers: think of a use for the characteristic side fins.

Weight breakdown. All data match the hull model used in the analysis of the hull, rounded up. I've increased hull strength reserve (and so weight) from the previous draft, to allow for higher sea state and mounting of artillery.
For the reference of skin strength, take a good 0.75" board of Lebanon cedar, 1" of oak, or 1.5" of softwood. These materials were used for building seagoing vessels of similar displacement. That applies to bending and compressive strength; by tensile strength, 4mm match an inch of steel or half a foot of wood, but unfortunately it doesn't matter as much. Compared to wood or steel, the skin is less stiff, allowing for more bending.

Note that it might be not advisable to use the second tank variant (ACF is a more modest name for carbon nanotubes) if you're playing strict MT. Better spend extra 1600kg and keep in mind the fuel boils off twice sooner if not used. Normal CF tank is current (~2000) technology. The ACF needs yet a few years to become well affordable. I'm using it just because, well, I've decided to play by common rules and not self-imposed strict MT ones. Also, ACF tank will incur $4 million premium, because in April 2007 ALC equipment shipment was pirated, creating a shortage.
P.S. If I design a successor, it will have multi-tank design. That's because I'm fed up with running around that huge tank just for weight economy.

"Liek? I luuuv mudkips!"
"So, would you ever *love* a mudkip, that is, insert a long thick cylindrical device into the mudkip's aft, of course..."
Great thanks to Hogsweat for helping to give Mudkip the image.
And, of course, it's updated to Version #34. That's the final update. It's 34m long and weighs 34 tonnes empty.*
It also features a lot of improvements for weight savings and not only, such as a beer mini-brewery in high endurance setup.
And, of course, the crew amenities on Mudkip leave almost nothing to be desired even by the highest standards for a warship. Each crew member has own cabin, which range up to as high as 10m^2 for the captain. While quietly and rapidly delivering the payload with stunning efficiency in a war, it also provides a lot in the peacetime.
There's, of course, also a less glamorous utility to these crew spaces - whenever something bad happens at sea, Mudskipper, 3 times faster than even the best of displacing warships, and not much slower than helicopters, will most times be the first to come. On such occasions, a few of these boats will easily rescue the crew of a large warship.
Note that the crew spaces carry about the same armor as the control deck, not much, but enough to take /b/tards with anti-materiel rifles and jeep M2 machineguns, in riverine and close littoral combat. No, it's not for SEAL insertion - even if stealthy for the radar, it's not as small as to hide from the eye - but marines would like it. Besides, it can work as a landing craft, not as good as hovercraft in entering the beach, but incomparably quieter and stealthier, similarly mine-resistant, and sufficient to get marines to 0.8m where they can walk the bottom. Though it's expensive for that role, but one doesn't build it just for that, it simply helps.
No ready modules today, so not yet the time to fear the Mudkip. You'll realize eventually that Mudkip feels herself in a sea of large ships just like F-22 in a sky full of Stratofortresses, but everything has its time.
// *One might wonder, is that a coincidence. No, not really. The trick is that same things can count as empty weight and load, i.e. crew quarters furniture and safety equipment (liferafts) can be either - so I just shifted them to get the figure.
