In the aftermath of two wars, and various skirmishes and so on, the Rhydinian Hegemony required a subfighter that could be deployed by it's colonial holdings, to patrol it's own areas, as well as respond to threats and or crises when a military unit might not be available. The Caysudr (Pronounced: "KUahae-seeoo-de-ra") is Rhydinian for Seamoth, and is typical of colonial design developed during the early 2000's with a lightweight, inexpensive hull comprised of titanium alloys. The fighter's low cost has kept it in production through to present date. No efforts have been made to rebuild the fighters with stronger materials, as per colonies themselves build the Caysudr.
The Caysudr itself is based on the Dnaycina Rihdan science and research vessel, a long standard of the colonial territories and indeed the core habitats of the Hegemony itself.
The Caysdur shares many features with it's predecessor, such as being able to take it's pilot to a depth of 2,668 meters (8,753 ft) in comfort and safety. Many of the ocean's most remarkable features, both geological and biological, lie within this depth range, including the sunlit zone, twilight zone and dark zone.
Features
• Full Visibility
The pressure hull of theCaysdur subfighter consists of a transparent acrylic sphere, which offers an unprecedented 320-degree view of the outside environment. Traditionally, deep diving submersibles have only been able to offer pilots and observers limited visibility through small viewing ports. The Caysdur's acrylic pressure hull configuration ensures the occupants can see both the submersibles’ external equipment and their surrounding environment.
• Comfort
The pilot sits comfortably upright on regular seating while cabin pressure is maintained at one atmosphere using a traditional metabolic make up life support system. Cabin temperature and humidity is maintained at a comfortable level by the submersibles air-conditioning system and all life support related parameters are monitored by the pilot, using sophisticated atmospheric sensors and sampling equipment.
• Ease of Handling / Thrusters
Each Dnaycina Rihdan is fitted with a single main thruster and (4) control thrusters controlled by a dual stick drive, of which the pilot grasps with both hands and can manipulate the control thrusters from there while utilizing the main thruster with forward or reverse pulls. The pilot, with only minimal training, can easily control all the movements of the submersible, because of the intuitive nature of the controls. The compact size and weight of the Caysdur submersibles compared with thruster power available results in an incredibly manoeuvrable craft with a high power to weight ratio. Unlike it's predecessor however, it is not fitted with lithium ion batteries but instead draws power from a micro aqua-return drive.
• Safety
The Caysdur submersibles have been pressure tested to 1.25 times their maximum diving depth with a designed safety factor of four times and a theoretical crush depth of over 4,000 metres (13,120 feet). The three main safety concerns for pilots in submersibles are engagement, accident, flooding, or entangelement. The Caysdur design mitigates these potential risks as follows:
*Entanglement - The manoeuvrability and superb visibility reduce the chance of entanglement to a minimum while the feature of diving two submersibles also offers the ability to give assistance should an entanglement situation arise.
*Fire – The principal cause of fire in a submerged vehicle is associated with electrical faults. The risk of fire has been diminished in the Caysdur by keeping all high current circuits outside of the pressure hull. Only small currents required to both power the internal equipment and control the external equipment are used within the hull. In addition, all equipment within the personnel sphere is halogen free, non-smoke producing and self-extinguishing. The Caysdur are also equipped with both a built in breathing system and self-contained oxygen generating re-breather units, which offers the pilot over 100 minutes of self contained life support.
*Flooding - The Caysdur are accessed through a bottom hatch. Flooding incidents typically occur at the surface in submersibles when the access hatch is opened prematurely allowing water to enter the pressure hull. Configuring the Caysdur with a bottom hatch eliminates this problem.
• Life Support
In the event an extended stay on bottom is required, the Caysdur submersibles are equipped with 72 hours of emergency life support, including carbon dioxide absorbent, food, water, basic first aid, waste disposal facilities, atmospheric sampling equipment and sufficient power for any communications that may be required.
• Tracking
An optional Track Point II system can be used to monitor the position of the Caysdur submersibles relative to the ship while they are dived. In this case, each submersible would be fitted with an underwater beacon that interfaces with the system, which is monitored by the base station aboard the mothership/colonial holding. This system allows the support ship to both follow and plot the position of the submersibles during a dive.
• Manipulators
Each Caysdur is equipped with two (2) six (6) function, rate-controlled, Mako sensory manipulators. These manipulators can either be operated by the pilot or the observer, with minimal training, because of the intuitive nature of the controls used. When in pursuit or in high speed, the manipulators can be folded and tucked back at the rear of the submersible by the pilot.
• Launch and Retrievals
The compact size and relatively small tonnage of the Caysdur make them less cumbersome than their predecessors. They can be launched and retrieved from small ships of opportunity in average to moderate sea conditions.
• Lighting
Any combination of lighting packages can be installed on the Caysdur. Lights available include 1200-Watt, 600-Watt, 400-Watt and 200-Watt HMI lights.
