The Kastrull is a dependable attack sub class bringing plenty of firepower to any fight, and although it's not very nimble, it does sport a drone gunship as standard. Keep in mind that with its experimental open ballast tanks, low tolerance to flooding and numerous crew stations, a large, experienced crew will get the most out of this sub.
–In-game description

The Kastrull is an Attack class submarine.

Notable Features

The Kastrull supports a Drone with a Coilgun.

The Kastrull has central open-top ballast tanks.

The Kastrull has 8 submarine weapons, including the drone. This makes it the most heavily armed gunship in the seas of Europa.

A good reason that a Captain would want a Kastrull is the gun drone that rests underneath the submarine. It can be controlled from the Drone Control next to the Bridge and can function as a great away-team backup since it wields a single Coilgun.


  • In Swedish, a kastrull is translated as saucepan or casserole. Considering the lid-less ballasts, the name is fitting. The Kastrull ballast section is a big heavy casserole without a lid.


  • (3rd Anniversary Update) Fixed some pumps in Kastrull working without power.
  • Fixed Kastrull's drone sometimes spawning inside the sub client-side in multiplayer.
  • Fixed bots sometimes deploying Kastrull's drone for no reason.
  • Fixed Kastrull and Typhon 2 using different id card tags than the rest of the vanilla sub ("idjob" instead of "id_job").
  • Made ballast pumps in Kastrull's drone indestructible (because they're impossible to access without breaking the walls/floors).
  • (Thunder Under The Ice) Fixed gaps sometimes getting linked incorrectly to the hulls between docking hatches, preventing water from flowing down from the lower hull in mirrored subs. Happened in mirrored Kastrull for example.
  • Fixed certain submarines spawning with a non-neutral ballast level (Kastrull seems to have been the only affected vanilla submarine). Happened because the game would determine the neutral ballast level from the first nav terminal it finds in the sub, without checking whether that terminal controls a shuttle or the sub itself.
  • (Embrace the Abyss) Fixed Kastrull's drone airlock not flooding correctly.
  • (Cave Update) Fixed Kastrull drone flooding when undocking using the button next to the hatch.
  • (Uncharted Depths) Added more waypoints around the drone so that bots know how to get around it when it's docked to the main sub. Fixed the airlock waypoints not being linked to the doors, causing the bots not being able to operate them.
  • (Halloween 2020: Creepy Creature Feature) Fixed the airlock waypoints not being linked to the doors, causing the bots not being able to operate them.
  • Fixed airlock warning light in Kastrull not turning off when the airlock door is closed. Fixed hull above drone not being connected to the rest of the hulls, preventing oxygen from flowing between the drone and the sub when docked.
  • (Downtime Update) Fixed bots insisting on equipping the diving suit before accessing Kastrull's drone.
  • (Moloch-sized Update) Fixes to waypoints in Kastrull, Berilia and Remora.
  • (Silky Smooth) Fixed flooding when the drone undocks. Fixed ballast pumps deteriorating in drone despite being unreachable by the players.
  • Waypoint fixes. Fixed flooding when the drone is undocked. Fixed ballast pumps in drone being off by default.
  • Fixed Kastrull's drone not being docked to the sub by default.
  • (Beasts Within) Introduced.
