Weapons
- Master Arm switch for torpedo firing
- 4 Deck guns with dual munitions (standard coil guns, control in forward battery room)
- 1 AA Gun with dual munitions (double fire/rotation rate coil guns)
- 4 Forward Torpedo Tubes with 6 spare torpedoes (rail gun with 4/6 nuke shells)
- 2 Aft Torpedo Tubes with 3 spare torpedoes (rail gun with 2/3 nuke shells I went with 2 instead of one like the real Type VIIC cause reloading after every single shot would be way too tedious)
- 4-way toggle switch for Attack Periscope with setting display (Atk Peri click to toggle light, F/A torps, AA Gun)
- Single launch Decoy/Depth Charge launcher with 4 manually loaded spares
- 4 Discharge Coils

Life Support
- Automated Oxygen System (charges all rooms to 100% oxy if any room falls below 60%)
- 2 Diving Airlocks (conning tower and below control room)
- Automated Drone Airlock (doors open when drone attached)
- Auto closing compartment doors. Will close 4 sec after water is detected (delay was added to give time to enter a flooded compartment for repairs).

Power Systems
- Fully automated electrical grid with manual input override
- Fully automated battery charging system with manual rapid charge override
- Semi automated Reactor (only need to control fission rate), will auto-shutdown if meltdown warning active for more than 8 seconds
- Automatic switch to battery power if reactor output less than 100kWm
- Power switch for docking port power
- Forward/Aft Battery room

Sub Control
- 4 Ballast tanks (neutral buoyancy of 0.5000)
- 2 Negative buoyancy tanks (empty for normal operations)
- Water funnelling system (will funnel water to the main ballast tanks if the adjoining room is over 75% filled with water
- Compressed air system (made from capacitor and small pumps)
- Sonar room (sonar monitor with mineral scanner)
- Radio room (Drone control with drone override and 3 on/off signal lights)
- Breach/flooding alarm system
- Switches for Exterior Lights, Searchlights, Coilgun Lights and Red Lighting
- Silent Running (locks reactor and fabs/deconstructor off, turns on blue lighting, switches dual main engines to dual shuttle engines)
- Crash Dive (shuts down ballast pumps and floods all 4 ballast tanks and both negative tanks)
- Blow Ballast (activates ballast pumps, uses compressed air to empty negative tanks will blow air into ballast tanks until negative are empty)
- switch to lock forward cargo room (to uses as makeshift brig)
- Lockboxes (Captain has access to all, Eng for Fuel rods, Med for toxin cabinets, Sec for weapons stores)
- Fabs/Deconstructor linked to scrap lockers
- Observation Periscope (2 searchlights + eng room cam)

Same features as 'Greywolf' apart from weapons. It features 3 deck guns and 2 AA guns.

- Main power switch to shut down drone when docked to prevent wasting battery power.
- 4 searchlights with switch for lights on/off.
- Automated airlock doors shut when water detected in airlock. Won't open again till the water is pumped out. Door shut override switches in forward and aft compartments, if either is on doors are forced open.
- Hatches auto shut when undocking to prevent accidental flooding.
- Single coil gun for defence operated by observation periscope when gun power switched on.
- Single Ballast tank with neutral buoyancy of 0.5000.
- Battery level display.
- Automated battery charge with manual override for rapid charge (remains at 0 when undocked unless manual override active).
