Colonial Fleet SMX-25

If you like it, please give me a thumb up! thank you!



If you want to switch to this sub in an existing campaign, DON'T select the checkbox of "transfer all items to new submarine", otherwise the drone will simply disappear, and its docking port will cause a lot of trouble.

The SMX-25 prototype, the "Advance", was built during the Golden Age of Human Exploration in Europa, and was part of the former Colonial Fleet. It was one of the few high-performance submarines designed and built to the standards of old Earth space warships in the Europan ocean. Unfortunately, due to its high cost of use, it has only participated in a handful of abyssal beast hunting missions since its service before being permanently sealed.
In July 22xx, the ship was found and salvaged by Zyleand Shipyard in an abandoned military base only 1km from the Europa surface. Thanks to the high design standards of SMX-25, its essential systems were not irreversibly damaged, though its storage devices were almost completely erased of valuable information due to prolonged exposure to Jovian radiation.
After a quick in-field repair, this old-age submarine, which had been dormant for nearly a century, was finally able to make its presence felt in the frozen ocean once again

Item number: 924(including drones)
Price: 8500mk
Size: 61x12m
Weapon: 3 chain guns, 1 fission laser main gun, 4 auto discharger, 1 depth charge launcher
Cargo: 30 crates

Modified chain gun:
- The warm-up time reduced to 0.5s and use coilgun ammo instead.
- However, the power consumption is increased and fire rate of chain gun is reduced by 33%.

Pulse laser main gun:
- The firing of main gun can be stopped any time, but it will only be available until it is fully recharged.
- The main gun is charged by a special reactor on the bow, and it takes 11 uranium fuel rods to completely recharge the main gun capacitor.

A periscope-controlled combat drone, double click to switch between move and fire mode.



Fast fabrication/deconstruction system, 4 times faster fabricate/deconstruct speed, lower the skill requirement to fabricate by 20%.

The submarine has an auxiliary engine, which cannot be turned on for a long time before it is fully upgraded, and the speed can reach 50km/h when it is turned on.

Since the cargo hold is a relatively weak point of this sub, so I made it possible to operate this sub there (? ? ? ).

An omni-id-card in command room, can open every doors/cabinet of wreck/outpost/pirate sub in vanilla game.

Flora-proofed ballast.

Backup battery array.

The cargo hold still retains a large number of old-time crates, although its safety measures have all been damaged and cannot be opened, but there are still many merchants willing to pay a high price to buy.

The shape of this ship is inspired by the realistic concept submarine SMX-25.

Btw, I don't know whether it's the Steam server or some other problem, I can't reply to your questions in the comment section, but I’ll still check your message or feedback from time to time, so feel free to leave a comment.
