(DISCONTINUED) Combat Submarine USS Alabama


This content is discontinued and should no longer be used.
Instead please download and use the SSBN 731 Ohio Class.


version actual 2.7.1

This ship is not a common vehicle of the editor. This mod recreates a simulation of underwater navigation, while transporting the players that operate the ship. Allowing to move, turn, submerge, emeger, armed with torpedoes, missiles, cruise missiles and nuclear missiles, this ship can fight other ships and submarines, and support the ground infantry, everything is managed from an area that simulates navigation inside of a submarine. and everything that is executed from the compartments, will be executed by the submarine that simulates the exterior of the ship.

the submarine that can be damaged by the enemies and everything that happens to the submarine. could harm players inside of the compartments, the players will feel movements, water pressure, lack of oxygen, inclination, pain, heat, radiation, among other characteristics, if the ship is destroyed, the players inside will die, if the ship damages. will flood the areas by water, they will feel a strong movement of S, blows, pain and bleeding, fire in compartments, among other actions, the players can repair the ship from the compartments, with tools, seal broken valves and extinguish the fire , repair engines and electronic boards, among other jobs, this work was done with the purpose that players entering the ship can feel that they are inside a real submarine and that they work inside as if they were in a real submarine.

You can obtain the manual of navegation this link:

Manual in Spanish:

Manual in English:

IMPORTANT INFORMATION, if you want to edit the missions with the USS Alabama should be the following information:

If you are inside the ship, and you close your EDEN server, your editor will remain dark

To solve it go to tools, and press the camera

Then press escape and close your Splendio camera.

Authors of the base this work

The 3d model of this ship is made by the author Gnat, you can locate the model that has been used for the alabama in the information that you find in the prolog of the navigation manual. The engine of movement of the ship is made by Mr. Stick_Hogue, they can locate their work from the prologue of the navigation manual.

Combat Submarine USS Alabama

This mod is apart from a submarine a modality of naval simulation with combat of different ways and in relation to terrestrial missions, it is very important that you read the manual of the Alabama before manipulating the ship, this mod was made with the purpose to work in milsin, military simulation, so it is not possible to manipulate it in a player, you need a crew of no less than 4 to operate it.

Submarine Militar USS Alabama, is a submarine navy, specially designed for the protection of maritime and terrestrial spaces, this mod is based on the simulated function of its operation in most of its aspects, so it will be necessary for a constant coordination and communication between the crew, the compartments that divide it, the function cameras, the tasks given, the position of government or ground control and command.

Version 2.7.1 instructions for the proper operation of the ship and the crew:

1- Download the compatible map package with version 2.7.1

Current support maps for the development of missions:

Duala Island
4 islands Mske

the ship can only be used in the predetermined missions, you can do the initial missions or edit your missions on that initial mission, to know how to edit it successfully you must read the last subject of the navigation manual. Soon missing maps will be published.

get the initial base mission from here Version 2.7 for both versions

Pack mission version 2.7 with new model version 1.0´╗┐


Old Version mission Pack for version 2.6

for the new update you can configure your server to your liking, the limitations have been corrected, you just need to have the most updated base map (2.7).

please read the manual for any concern and if you have any questions you can do it through the comments, If you suffer some bigs or do not manage to operate the ship, please inform in the comments, to solve the problem as soon as possible, and I will gladly help you,

To install (DISCONTINUED) Combat Submarine USS Alabama you should use modfolders to keep it seperate from the official game content to prevent issues.
With Arma 3 you can use different ways to set up your modfolders to use custom content you have downloaded.
