- Retrofit Lab requires a Naval Lab Level 7 in order to be built.
- Retrofit Lab can be upgraded to level 5.
- Retrofit Lab Level 5 gives access to any level 5 retrofits, retrofit Lab Level 4 gives access to any level 4 retrofits, etc.
- The related blueprint is also required before the retrofit research is available.
- Only blueprints are retrofittable. For example, the Hammerhead A, Hammerhead B & Battle Barge A are all retrofittable. However, the Hammerhead and Battle Barge researched in the naval lab are not retrofittable.
- Retrofit time increases according to the number of hulls of that type actually built.
- Hull retrofits are designed for mid to high level players, 35 and higher. Kixeye designed the other retrofits for players level 55 and higher. The uranium cost is a barrier to low and mid level players.

In March of 2014, many of the builds and research times have significantly decreased. The old build times can help you estimate the new build times. Resource requirements remain the same.
