The one in charge of selling Submarines wears the Boiler Suit and an unpowered Headset with the Sub icon above them. They have a Wrench, a Screwdriver, a Diving Mask and a Toolbox containing a loaded Welding Tool, a Welding Fuel Tank, and 1 Aluminum. Their station is the Maintenance bay, easily recognized from all the Submarine Blueprints hanging on the wall.
When interacting with them, an interface similar to the Outpost Terminal appears, showing all available subs for sale, with the fixed price and its class specified, along with the options to either Purchase or Purchase and Switch (This function is identical to the Switch option in the Outpost Terminal). There are 10 vanilla subs available for sale, plus any up to date modded subs the player/host may have installed.
Sub
Class
Description
Price
Azimuth
Scout
Superior speed, sleek design, and quality-of-life systems make this submarine a favorite among wealthy Coalition captains who manage to make it to retirement.
10,000 mk
Dugong
Scout
Compared to larger vessels, the Dugong series is overshadowed in all aspects except one: their reliability for their price is world class. They're lacking firepower and speed, so smart maneuvering is key.
6,000 mk
Orca
Scout
With a relatively high top speed and fantastic ascent and descent characteristics due to her 3 large ballast tanks, Orca class subs are agile vessels, let down only by their small compliment of weapons, unreliable engine and reactors with a greater than average hunger for fuel.
9,000 mk
Humpback
Attack
A former military vessel, WH4-L3 'Humpback' has been outfitted to withstand most of the dangers in deep Europa. Her relatively high velocity is offset by low maneuverability. As she's still boasting an older model reactor, power needs to be supplemented by a backup battery array or the crew will find themselves unable to run all of the new equipment.
7,800 mk
Kastrull
Attack
The Kastrull is a dependable attack sub class bringing plenty of firepower to any fight, and although it's not very nimble, it does sport a drone gunship as standard. Keep in mind that with its experimental open ballast tanks, low tolerance to flooding and numerous crew stations, a large, experienced crew will get the most out of this sub.
21,000 mk
Typhon
Attack
Typhon class subs are known for their brutish appearance, reasonable array of light and heavy firepower, and their general dependability. Any captain should be aware of their poor rate of descent and unimpressive top speed.
11,500 mk
Typhon 2
Attack
Typhon 2 is an overhauled version of the venerable Typhon class of sub. Serving as a heavy gunship, the Typhon 2 class subs remain slow and ugly, but with the benefits of better survivability for their crews.
20,000 mk
Berilia
Transport
Berilia is one of the biggest cargo ships on Europa. Its two engines and three ballasts require a copious amount of power to operate, and keeping the machinery in good working condition is a handful for even a moderately large crew.
15,000 mk
R-29 "Big Rig"
Transport
R-29 is a heavyweight transport ship. While not terribly well armed against Europa's underwater denizens, it has been retrofitted with two powerful electric discharge coils. Original design by rav2n.
14,500 mk
Remora
Deep diver
A range of customization options are available for Remora. In this model, some of the main hull space has been replaced by a detachable ballast and a remote-controlled drone. A large crew is needed to operate this submarine.
16,000 mk
Improvement[]
Subs may have their hulls and systems upgraded in a variety of ways to improve durability and effectiveness. These are purchased from the engineering crew chief at any station, who is usually in the station engineering section with the reactor and the oxygen generator, plus a fabricator can also spawn randomly in this area. They can be seen wearing the Crew Chief's Outfit and an unpowered Headset with the Upgrade symbol above them. They also possess a Wrench, a Screwdriver, a Diving Mask, a loaded Revolver, and a Toolbox containing the same items as their sub selling partner.
The crew chief offers multiple Upgrades per Upgrade category to further improve them, but each additional Upgrade in the same category also costs more than the one before. Thus, more money buys more and nicer things. Each sub may be upgraded independently of all the other subs, so how many different subs the player chooses to invest their hard-earned marks in is up to them. The crew chief also offers sub Maintenance services to ensure the safety of the crew on their next trip, provided they can afford such services.
When purchasing and switching to a new submarine, it will only be delivered and available for use once the crew leaves the Outpost. During this period, the Upgrade interface will become inaccessible as the crew chief isn't able to work on any of the crew's newly purchased subs until they have been delivered.
The pricing of their Upgrades and Maintenance services is dependent on the RP of the current Outpost, specifically 1 RP is equivalent to 0.5% of the price. Therefore, the maximum discount is 50% off at 100 RP, and at -80 RP they will charge 40% extra. Much like Store, the price gets higher beyond -80 RP as the entire Outpost hound for the crew's blood.
Upgrades[]
There are 13 parts of a submarine, each with different types of Upgrades and each Upgrade has multiple levels. There is a total of 22 different Upgrades across all parts. Once the first level of an Upgrade is purchased, the second level will cost more than the last by a percentage. Each Upgrade has a different initial and maximum percentage spike in price and depending on the number of levels, the percentage price spike of 2 consecutive levels is different between all Upgrades.
Upgrade Price Calculation
An Upgrade has Y levels in total and its first level costs X1 marks, then X2, X3,... then pre-final level costs XPre-Max and final level costs XMax. Its initial cost increase is A%, maximum cost increase for the last level is B% and Z% = (B% - A%) / Y is the cost increase between each level. Therefore:
After paying X1 money for the first level, the second one will cost X2 = X1 + (A% + Z%). The third level will then cost X3 = X2 + [A% + (Z% * 2)]. Then the fourth level is X4 = X3 + [A% + (Z% * 3)], and so on... Until the final level is XMax = XPre-Max + (B% - Z%). NOTE: Some prices after adding the level's cost increase become decimal numbers. However, the game doesn't take the decimal part into account, but only the whole number part as the actual price, which is then used to add the next level's cost increase. So for instance, even after doing the calculation and the price of a level is X.99 mk (decimal part being 0.99), the actual price that is also displayed in game is just X mk.
The following tables show all values regarding each Upgrade in different Upgrade categories at 0 RP.

Maintenance[]
Keeping the sub and its installations in good condition is crucial for the crew's survival when traversing the Europa's ocean. Sub Maintenance can be done manually by anyone, preferably individuals skilled in those aspects, mainly Mechanics.
Manually repairing things can be a tedious and difficult task depending on the structure of a sub and the current state of a sub. The quickest way to maintain a sub is to just stop by an Outpost, spend money in Maintenance services, and get everything repaired automatically instead.
However, things like shuttles (drones) that come with certain subs can't be recovered manually if they get destroyed or the crew happens to lose them along the way. The only way to retrieve the lost shuttle is to replace it for a new one in Maintenance.
There are 2 types of services in Maintenance: Repair and Replace. The repair service is available for purchase once per visit to an Outpost. The replace service is only available for subs with built-in shuttles that have lost said shuttles and also only purchasable once per visit to an Outpost.
