Corollary II

The Corollary series was initiated after the Lemma Series and specialized in salvage operations while continuing its fluid dynamics principles. It is designed to replace various outdated transport submarines. The entire series comes with the following standard configurations:

• Manual: Built-in Ship Manual in terminal that located in command room
  
• Lock: Control for locking the brig
  
• Dock: Control for the lower docking chamber
  
• Hatch: Manual control for the upper and lower docking chamber airlocks
  
• Water Valve Mode: Additional ballast tanks
  
• Mobile Shelves: Shelves that can move in and out of the submarine
  
• Abyssal Miner: A mining vessel capable of high-speed dives

In the campaign set in Hellish difficulty with Jupiter radiation enabled, it offers a satisfying gaming experience.Lightweight design, thus no fancy decorations, but it ensures a smooth gameplay experience without any lag. Please read the instruction manual before embarking.

Spec model Features

• Armor : Strengthened harden shell, including inner armor in the electric room.
  
• Processing Equipment : Only equipped with a fabricator and decomposer, but enhanced efficiency.
  
• Unique sub-system : Note-class external operation autonomous follow drones.

Corollary II is a medium-sized transport submarine specially designed by the Europa Union Design Bureau for salvage and mining projects in the Europa Ridge region. It equipped with a mineral scanner and is intended to replace outdated and bulky R29[barotraumagame.com]. The series features a diamond-shaped spindle design, enabling the installation of small engines with highly efficient fuel economy. Sacrificing maximum speed, the saved power is allocated to the processing equipment, giving them unparalleled efficiency compared to other types of submarines.

As the first developed model of the series, the Design Bureau conducted extensive research before starting. Integrated many excellent designs and established the foundation for this series. As a transport submarine, its cargo hold is designed to be embedded, avoiding the possibility of tragedies caused by obstructed firing arcs. During transportation, the cargo hold is welded to the hull. To address the risks associated with welding, in water valve mode, the cargo hold functions as an additional ballast tank, and the pumps inside it are overclocked. The entire ship provides a total of 48 crates of cargo capacity. The cargo hold also serves as additional ammunition storage, allowing an astonishing amount of supplies and ammunition to be packed into this medium vessel.

As a specialized salvage submarine, it is equipped with a proposition-class mobile cargo container which inspired by 逆戟鲸2-T2攻击型 and Ero-锤击点-海盗型. Both submarine and cargo container are equipped with controllers, allowing the salvage crew outside to easily retrieve harvested supplies and ammunition back. To prevent derailment and leakage risks, the mobile cargo container is automatically locked when sub is not hovering. The crew will not sort the items inside the mobile cargo container, which brings some inconvenience. However, captain can place special ammunition on it for specific needs. Consequently, the cargo container's berth is reserved in gunnery chamber and adjacent to engineering compartment.

Another notable feature is the Conjecture-class Abyssal Mining Craft, which is inspired by Bullfish. True to its name, it's design for abyss mining. Once an abyssal island is located, up to three brave miners can board this craft and descend at maximum speed. The craft is waterproof and shock-resistant. Upon a hard landing, craft's omnidirectional searchlights and oxygen tank can support mining team's operation, but only as long as craft's batteries are not depleted. Abyss is the backyard for behemoths, and it is a terrifying and agonizing time for the miners, whether they evacuate before being detected by the behemoths or wait for the mother ship to distract the behemoths and return. Some people are devoured by the behemoths during the retreat, while others never receive the awaited rescue from the mother ship and ultimately suffer a painful suffocation in the pitch-black abyssal island. Those fortunate enough to succeed will reap generous rewards. Regardless, let us praise these warriors, as William A. Zeppeli said, "The human hymn is the hymn of courage, and the greatness of humanity is the greatness of courage."

In terms of armaments, the Corollary II retains the modified Chaingun design from the Lemma series. Allows for the alternating firing of two types of ammunition. This leads to selection of ammunition combinations based on different targets. Additionally, the large turret hardpoints mounted on the top and bottom of the Remark-class shuttle can be optionally installed at the captain's expense to provide heavy firepower. Whether facing conventional mining, cargo transportation, salvage operations, or venturing into the abyss, the Corollary II is well-equipped for the task. May every captain of it fill their cargo holds and return home in triumph.
