Uses
Specifications
It can only be deployed in deep water, at a depth between 15 and 30 meters.
It explodes on contact with a submerged vessel (regardless of its faction) and deals 1350 High Explosive damage.
A deployed mine despawns after 48 hours (48 in-game days) if it isn't triggered.

It cannot be deployed near Region borders.

Storage
The E680-S Rudder Lock does not stack in inventories (1 per slot).
It is a Large Item, a soldier can only carry one at a time on their shoulder.
It can be stored in Base stockpiles but also in Material Pallets, Rooster - Tumblebox Trailer, Material Transfer Stations, or Storage Rooms.
E680-S Rudder Lock crates can be stored in the stockpile of a Storage Depot, Seaport, or Storage Ship. Crates can be submitted to any stockpile that accept E680-S Rudder Locks to transfer their content into it.
Tactics
Given its minimum depth of 15 meters a submarine can avoid mines by going close to the surface.
Deploying Sea Mines next to a destroyed drawbridge ensures that Submarines won't be able to pass through.
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.
