Combat Submarine: The Grauwal by EINSCHLAG
G2 Grauwal by EINSCHLAG
Classic Diesel-Electric Attack Submarine
The Grauwal is an attack submarine combining diesel and electric propulsion with manual systems. Features torpedo/missile armament, deck-mounted cannons, and engaging hands-on gameplay. Diesels can run submerged for underwater battery recharging. Built for players who want engaging submarine combat without too much automation.

NEW
[list]

[/list]
Quick Start
[list]
[*] Close all hatches
[*] Enable "Diving Fins" at Depth Operator Station
[*] Start engines or electric drive
[*] Set target depth and throttle up
[/list]
Operations
Diving & Surfacing
Close hatches, verify pressurized air tanks (green gauges), enable Diving Fins, optionally fill dive ballast and balance pitch, start propulsion, set target depth. Fins auto-hold depth (periscope: 10). To surface: Empty ballast, set depth to minimum (3).
Balance & Trim
Weight shifts as fuel burns and weapons launch. Fins auto-level when moving; manual balancing needed when stationary.
[b]Ballast Tanks Station:[/b] Use Vessel Pitch dial, manage bow/stern tanks for pitch control. Bow tank doubles as torpedo tube pressure chamber. Torpedo Tube Leveling Tank auto-fills (double water added, counter by draining ballast). Dive ballast draining uses pumps and compressed air. Multiple air tanks allow individual management. Bridge is central air hub with vents throughout.
[b]Engine Room:[/b] Pump fuel between tanks, select tanks per engine via valves or use reserve tanks. Emergency dump: Open ceiling valve and enable "Pump OUT".
[b]Torpedo Room:[/b] Position torpedoes symmetrically for roll balance. Tube flooding/draining affects buoyancy.
[b]Other:[/b] Monitor interior water on bridge (bilge pumps in Bridge, Torpedo, Engine, Air Rooms). Missile weight affects pitch. Dinghy deployment affects pitch/buoyancy.
Refueling
Connect external fuel port. In engine room: Open "Refueling Pumps to Bow/Stern Tank" valves, toggle "Pump IN". Reserve tanks auto-refill from stern fuel tank.
Dinghy
Use crane handle to release hardpoint, hoist/move with crane, detach rope. Use handles on [url=https://steamcommunity.com/sharedfiles/filedetails/?id=3598220528]dinghy[/url] to maneuver. Reverse to reattach.
Weapons
Torpedoes
[b]Fire:[/b] Check loaded (water ~0, hatch unlocked, torpedo inside, Release key off), close hatch, enable "Loaded & Closed" key, press "Flood" (rapid blink), wait for steady indicator, aim, press "Launch" (auto-closes/drains). Hold Launch to fire when flooded.
[b]Reload:[/b] After drain, open hatch, use gantry winches to position torpedoes. Optional: Top hatch reload (respawn is faster).
Missiles
[b]Fire:[/b] Arm system (flip switch above periscope), press launch hotkey.
[b]Reload:[/b] Drag new [url=https://steamcommunity.com/sharedfiles/filedetails/?id=3384224854]Tulpe Missiles[/url] to hardpoints, disarm, hold launch 10 seconds (counter blinks to "8").
Battle Cannon
Surface, crew cannon on deck (180° bow arc). Auto-reload when seated, fire until depleted. Reload: Use Ammo Loading Conveyor to pass ammo from deck to torpedo room, load into belt.
Machine Gun
Detach rope, grab handle and fire (left then right gun). Secure rope after. Reload with ammo on conning tower.
Exterior Auxiliary Hardpoints (Default: Torpedoes)
[b]Fire:[/b] Arm system (flip switch above periscope), press launch hotkey.
[b]Reload:[/b] Currently not supported / Respawn required
[b]Release:[/b] There are handles on deck besides the conning tower marked with yellow arrows
Tips
[list]
[*] [b]Red lighting:[/b] Auto-activates when lights off. Flip switch on periscope for complete dark.
[*] [b]Radar:[/b] Surface only. Use sonar underwater.
[*] [b]Max speed:[/b] Dive, both engines, max RPS, disengage Main Generator, reach 90kts (engines overheat quickly).
[*] [b]Battery charging:[/b] Engines have small generators, but use Main Generator for charging (reduces propeller power).
[*] [b]Engine cooling:[/b] Post-run cooling default (runs until <40°C, consuming power/creating noise). Disable for silent runs.
[*] [b]Emergency escape:[/b] Exit through empty torpedo tubes (use interior buttons, wear diving gear from torpedo room).
[*] [b]Heavy winds:[/b] Submerge to avoid capsizing.
