G7e "Shipwreck" Torpedo

G7e "Shipwreck" Torpedo design is inspired by the literature describing wars from Old Earth and realization that stand off attack capabilities would enhance submarines' capabilities against alien wildlife or hostile submarines. Aptly named "Shipwreck"torpedo, is a fire and forget weapon, putting minimal demands for modifications on existing submarines. It automatically activates after undocking and becomes armed after traveling approximately 20 meters. Its warhead delivers explosive and EMP damage.

Other features

Engines activate automatically after torpedo undocking from the dock connecting it to the submarine. The game sets no limit on docking collars dimensions when it comes to the docking but the torpedo docking collars er 0.1 m and are positioned top and left (stern).

Torpedo is armed after traveling 20 meters after undocking from the sub.

If it detects target within 10 meters (monster, wall of a submarine or terrain or human) over or under the tip of the torpedo it will cut the engine and either descend or ascend towards the target (which means it can be decoyed by enemy submarine speeding away close to the bottom). When sensor in the tip detects a target within 4 meters of the torpedo it will detonate its load. Breaching the hull of the torpedo will also trigger its load.

If no target is detected after 150 meters, torpedo will reverse its direction and travel for back for 70+ meters before reversing its course once again and searching in other direction. This search pattern will repeat itself until batteries run dry.

Since AI thinks it is a shuttle/submarine (which it actually is), the torpedo will function as decoy, making monsters chase the torpedo.

Advice on usage and mounting

The torpedo is designed for stock submarines so if are using one of those 50 km/h+ submarines with 48 m/s diving speed, you can easily damage the torpedo if you crash into it (F=ma). Avoid crashing into torpedo by being easy on maneuvering.

Note that in current version of the game, a shuttle/torpedo can easily get snagged on the hull of the submarine once released. So after lot of testing, best results are achieved if the torpedo is mounted below the submarine.

Avoid launching the torpedo while going at flank speed forward. The torpedo will activate after traveling 20 meters and if you are going at flank speed (and especially in a non-stock submarine that has boosted engine values), the torpedo may not manage to clear the sub before activating.

Do not launch the torpedo close to the bottom (under 10 meters from the bottom). The game does not differentiate between cave wall or submarine wall, which means that sensors in tip of the torpedo can be easily spoofed by the bottom.

I recommend linking the docking port connecting the torpedo and sub with sub's power network if you are going to run lengthy mission.

NB! Be warned that you have to redesign the torpedo with hatches or similar if you intend to use it in campaign. Due to some game mechanics, equipment such explosives in detonator are not replenished after you replenish this torpedo. This design is intended only for missions.
