Retrofit Your Ships
Some of your shipgirls can receive a retrofit. Retrofitting provides enhancements.
To retrofit a ship, you go to the Retrofit tab on the ship details page. Dock -> Click a Ship -> Retrofit. Only some ships have retrofits, but in the dock, you can filter on Retrofit Available.
Retrofits are done in order, with early retrofits enabling later ones. There will also be level and limit break requirements, and each retrofit will require various parts such as Battleship Plans, Gun Parts, et cetera.
This is the current state of Warspite, with three retrofits completed. I am not currently using this shipgirl in an important role, so she is not fully limit broke. If I click on the completed retrofits, I see:
- Hull Improvement: +70 HP
- Reload: +5 RLD
- Anti-Air Gun: +5% Anti-Air Efficiency
If I perform the retrofit:
- Anti-Air: +10 AA bonus
- Anti-Air Gun II: another 5% Anti-Air efficiency
- Hull Improvement II: another 70 HP
- Reload Enhancement II: another +5 RLD
- Firepower: FP +5
- Main Gun: Main Gun Efficiency +5%
- Modernization: I'll talk about this below
- Tactical Skill: Learn Skill: The Royal Navy Legend
I believe Modernization will change this Super Rare ship to Ultra Rare. And Tactical Learning adds the Locked skill to this ship.
Completing retrofits is worth it, but you use valuable resources, so retrofit your most important ships first.
Drops Required
The drop you'll need the most of are Ship Plans specific to the type of ship you're retrofitting:
- Destroyer Retrofit Plans: Hard mode x-1, chapter 3 and above
- Cruiser: Hard mode x-2
- Battleship: Hard mode x-3
- Carrier: Hard mode x-4
In addition they drop as T1 (grey), T2 (blue), T3 (gold). You can convert 6 T1 -> 1 T2, but you can't combine T2 to get T3. You'll also find them in some commissions, missions, some research, and the Medal Exchange Shop.
