Background: Many specialists in naval strategy will inform their audience that the future of naval war lies in submarine warfare. Submarines are stealthy and lethal, capable of performing a range of missions from covert action and espionage to continent-annihilating thermonuclear strikes. However, for them to do their job, submarines require continuous logistics support from surface ships. Food, water, weapons resupply, and repairs all require a surface ship, as do medical services – a submarine lacks the facilities for any but the most basic medical treatment. For urgent surgery, and even for something as simple as a root canal, a sailor must be removed to a surface vessel. (Imagine performing
routine patrols when the First Mate is half-delirious with tooth pain!)
In light of this, Hammond Motors, a manufacturer mostly famous for a range of logistics vehicles and cargo vessels, invested over five hundred billion dollars in purchasing production facilities, rights, and associated know-how from ANEP. This established a large-scale production capability for Hammond Motors in Anagonia, while also allowing it to begin developing its own submarine tender based on the AEST-1108 Export 1108 Class Export Auxiliary Submarine Tender Ship. In the tender hands of Allanean designers, the submarine tenders underwent a range of review, until it finally become the Sedna class.
Onboard equipment: The Sedna is equipped with a full set of the necessary equipment and laboratories to inspect and maintain onboard submarine equipment, from electronics to torpedoes to the sailors themselves, including four fully equipped ICUs, six barometric decompression chambers, an MRI machine with the full capability to carry out Magnetically Focused Guided Ultrasound surgeries, and a fully-equipped dentist's office. In the event that an emergency may require specialized parts, or airlifting a sailor to receive more advanced medical treatment, the Sedna is equipped with a helipad.
In dire emergencies, the Sedna is capable of responding to submarines or ships suffering dire emergencies with rescue and repair response. For this purpose it carries several ROVs, two underwater operations hardsuits, and two Capibara-class rapid rescue boats.
Electronic Load Handling System: The most important element of any tender ship is tracking the loads it carries. For this purpose, the Sedna is equipped with a quadruple-redundant logistics management computer. Linked to portable scanning terminal issued to the crew, the logistics management computer contains a real-time record of all torpedoes, mines, supplies and spare parts. The system maintains a record of the relevant logistics data – the size and dimensions of the items, their expiration dates (where relevant), and the location and status of each item. When the time comes to load a submarine with items, the ELHS automatically prepares a plan which contains a detailed order in which the items are to be unloaded, the most efficient routes the crew must take through the cargo hold to access and move the items, etc., and submits it to the relevant officers aboard ship for approval and last-minute corrections.
Deck cranes: The Sedna-class is equipped with a pair of high-yield deck cranes, connected to the ELHS, and capable of transloading heavy weapons packages and other cargoes. With the two deck cranes, the Sedna is capable of rearming two submarines at once.
Do not repeat NOT utilize the Sedna-class for reactor refueling of nuclear submarines, whether at sea or at pier. The ship is explicitly not designed to be used in this capacity, and Hammond Motors rejects any liability resulting from the use of the Sedna in a reactor refueling capacity. We caution in the strongest terms against performing any nuclear submarine refueling outside the context of a secure drydock.
Alternate uses: Other than being deployed as a submarine tender, the ship can be deployed as a diver tender and deploy small teams of Navy operatives, or use its communications facilities to communicate with, and control, UUVs, which can be stored aboard the ship and deployed from it, or – in the case of larger armed UUVs – also resupplied from the ship in the same way as submarines can be.
