| — In-game description |
The E680-S Rudder Lock is a large Sea Mine used to build E680-S Rudder Lock Minefields either underwater to defend against Submarines or on the surface against all naval vehicles.
Description
The E680-S Rudder Lock is a large explosive. It only detonates on contact with any armored vehicle, friendly or enemy. The explosion deals 1350 High Explosive damage in a 7.5m radius. As a Large Item, the player can only carry one in their large item slot, occupying their hands. It is designed specifically as an anti-submarine or anti-ship tool, to kill them or prevent them from accessing an area.
Unlike the E681-B Hullbreaker Mine, its explosion can create leaks in Large Ships.
Usage
Large Item Handling
It can be picked up from the ground with 
and dropped on the ground with (or 
+ if another "V" interaction is available). It can be submitted to a structure/vehicle's stockpile or inventory with or by clicking the Submit Large Item 
button in their interface. It can be retrieved from a Material Pallet, Rooster - Tumblebox, or Storage Room by pressing without having to open their interface. It is automatically dropped if the player draws a weapon or equipment.
Production
| Site | Input(s) | Output | Time |
|---|---|---|---|
 Ammunition Factory | 1 x Construction Materials  8 x Heavy Explosive Powder  4 MW of power  | 1 x E680-S Rudder Lock  | 00:01:30 |
Tier 2 Facilities must be fully researched in the Weapons and Structure 
Tech Tree in order to be produced.
Individual E680-S Rudder Lock in personal orders can be retrieved as reservable crates from a logistics vehicle with 
> Retrieve as Crates (1 per crate).
Storage
It does not stack in inventories (1 per slot) except in ammo slots dedicated to it in certain vehicle or structure inventories (varying stack sizes).
It can be stored in stockpiles of Bases (32k max) but also in Material Pallets (60), Rooster - Tumblebox Trailer (20), Material Transfer Stations (1000), Small Flatbed Car (50) or Storage Rooms (100).
Crates of E680-S Rudder Lock can be directly submitted to any item stockpile that accepts that item to transfer their content. The crates can also be stored in the crate stockpiles of Storage Depot/Seaport/Aircraft Depot (1000 public, 100 per Reserve Stockpile), Shipping Containers (60), or Storage Ships (1000).
It can be transported by almost any vehicle with inventory slots, but is most commonly transported by Trucks, Small Flatbed Car, or shipping vehicles carrying Material Pallets. Delivering it in crate form is possible but extremely inefficient.
Trivia
- When the E680-S Rudder Lock was introduced in 1.54 Naval Warfare, it was Colonial-exclusive. This was due to them not having any ships that could trigger them. This was changed in Update 1.56, when the Colonials got their submarine, meanimg that Wardens had a underwater vehicle they could attack with Sea Mines.
