Atgeir Class Hunter/Killer Submarine

Will Atgeir get equipped for the weapons DLC? No, as its fire control/torpedo loadout is too out of date.


Back when I made my first submarine in stormworks, I was tired of seeing submarines that could barely go 1-2km underwater because of pathetic electrical capacity or using a patched infinite electricity exploit. I wanted to make something that could really give you the nuclear submarine experience. However, as time progressed and I learned more, it became really easy to make a jet powered submarine, and the performance grew more and more crazy as a result. By the time I made Robert 3, it was more like a fighter jet than a submarine. Therefore, for my next sub I decided to purposely shoot myself in the foot and try to make a proper, grounded submarine. I'm proud to present the Atgeir Class, my first diesel electric sub as well as one of the first submarines in stormworks to feature SONAR guided torpedoes.

The core of the Atgeir, as one might expect from a diesel electric submarine, is first and foremost electricity. With more than 300 batteries split into a primary and secondary cell, the Atgeir can travel good distances underwater(by diesel electric standards). Additionally, needing to recharge your batteries doesn't necessarily mean you have to surface. With the addition of a snorkel, Atgeir can run it's diesel engines at up to 9m underwater.

While the initial interior appearance might seem less technologically advanced than the likes of the Robert 3, I specifically decided to stay with a more analog decor to both keep the submarine feeling relatively grounded in reality and to free up the logic load for the fun toys in the fire control room. This does not mean that Atgeir handles poorly, as in fact it's probably got the best ocean going handling of any of my submarines. It is capable of maintaining a set depth at as low of a speed setting as 7kph, perfect for lining up ambush attacks or creeping away.

Speaking of attacks, the Atgeir is well equipped. Not only featuring Pufferfish's sonar guided torpedoes, the Atgeir has the unique ability to switch between 4 different guidance modes (sonar guidance, radar guidance, periscope laser camera guidance, and manual GPS guidance), meaning that there really isn't an ocean going target that you can't fire at. Atgeir also has a full ECM(electronic counter measure) suite including a frequency sniffer, radio direction finder, and signal jammer, making sure that you can sink your targets unopposed.

I'll leave the rambling description at an end for now though, as there is a lot I could go on about on this boat. I'll close this section saying I hope you enjoy this submarine, and sorry to anybody who might have been looking forward to a jet submarine from me.



>>>A brief guide to using the fire control system<<<
------------------------------------------------------

On the fire control system, there are 4 possible methods to designate/aim at a target. SONAR, RADAR, the laser from the periscope, and manually setting a gps waypoint. The selected guidance mode can be seen on the instrument panel with indicators. The information displayed on the dials/gauges will correspond to the currently selected targeting mode.

To utilize the sonar or radar, make sure you first switch them on at the adjacent station. To save on logic/electrical power, there is only 1 radar and 1 sonar installed on the boat. They cannot do double duty, meaning that you have to choose to have it in search or in targeting mode. Search mode is the default mode, and to switch to targeting use the flip switches labeled "Slave SONAR/RADAR to fire control". The gauge display will then show the facing yaw of the sonar/radar in degrees relative to the sub. When using the sonar/radar, it will automatically remember the relative bearing of targets above a certain target mass(chosen via the keypad in the top right). This can be useful to filter out smaller unimportant targets like crates and sharks, as well as look for a specific target if it's radar/sonar mass(radar/sonar mass is acquired from signal strength*distance) is known. Additionally, you can adjust the radar/sonar FOV with the topmost throttle lever. A higher FOV will mean it is easier to detect targets, but the information from those targets will be less accurate.

The rest of the fire control system is pretty self explanatory, but let me know if you have any questions regarding it. I know that it probably seems primitive by other people's standards, but it's a first for me and I will eventually update it as I learn more. Suggestions and calling out problems is greatly appreciated.

Very big shoutout to Pufferfish for making the first sonar guided torpedoes in stormworks (https://steamproxy.net/sharedfiles/filedetails/?id=2424793308) as far as I can tell, they are a huge step forward and I will keep incorporating the improvements he makes to them into this submarine for the foreseeable future.

*Just a final note regarding the sonar/radar. Sonar and radar, especially sonar, are very inconsistent in stormworks. You can be doing everything right and it will still have trouble detecting targets. This is just a game issue found with every sonar/radar setup.
