Playstyle

Overview

Júpiter is a Tier I Spanish cruiser - a tutorial-tier ship. The kit is for learning basic mechanics: movement, aiming, shell travel time, gun rotation, and reading the minimap. Match impact comes from making fewer mistakes than the other Tier I players, not from gear advantages. Notable: fast acceleration (6 s).

Positioning

Stay near your team; do not push ahead alone. At Tier I the goal is practicing the basics, so pick a teammate to follow and learn how to lead your shots while their ship is in your field of vision.

Potato Avoidance

Sailing in a straight line

Even Tier I players will lead a predictable target; learn to make small course changes between salvos to break enemy aim. This is the single highest-impact habit to build at this tier.

Signature Traits

Fast acceleration

~6.0 s to max forward speed, top quartile of T1 CAs. Rebuilds speed quickly after a turn or stop. (Acceleration decode is validated in-game but not yet confirmed across every ship.)

Slow for the class

18.5 kt, bottom decile of T1 CAs. Hard to rotate flanks or disengage; commit positioning early.

Thin armor

10.0 mm max plate, bottom quartile of T1 CAs. Citadel windows open against peer-tier guns.

Acquisition

How to get Júpiter

Júpiter is available in the Júpiter branch of the Spain Tech Tree as an early line ship. Official source cards below may also show its temporary Early Access window before it became a normal Tech Tree unlock.

Magazine HP

The magazine is the module a detonation comes from. Penetrating hits to it raise the detonation chance from 1% toward 30% as its HP is worn down, so a larger magazine pool rides out citadel hits longer before a detonation becomes likely.

AA threat index82

SUM over AA auras of (aura DPS x aura range km). A plane crossing the AA bubble is exposed to each aura for a time proportional to that aura's range, so long-reach DPS is worth more than the same DPS in a short bubble. Units: DPS*km; used to rank overall AA threat across the cohort.

Armor

Hull HP 14,300, distributed across 5 hull zones, each with its own plate thicknesses, saturation cap, and pen thresholds. HP caps are the exact in-game values, not estimated.

Section	Plates	HP cap	Threats	Tactic
Bow	10 mm primary (range 6–10 mm)	800 (6% of HP)	Overmatched by 150mm+ (Celebes, Königsberg)Angle bounces 127mm10 mm: HE pens from 127mm+	Bow-tank fits behind this exterior plate. Saturation is FAST here; the cap is often only a few thousand HP.
Stern	10 mm primary (range 6–10 mm)	1,600 (11% of HP)	Overmatched by 150mm+ (Celebes, Königsberg)Angle bounces 127mm10 mm: HE pens from 127mm+	Mirror of bow. Same fast saturation.
Citadel	10 mm primary (range 6–10 mm)	≈ 165,500 (effectively no cap)	Citadel pen ×0.50 damageOver-pen: ×0.10 damage	Effectively no cap; citadel pool sits at ~165k HP on every ship. Damage is gated by pen/over-pen multipliers instead (×0.50 direct pen, ×0.10 over-pen).
Superstructure	6 mm	2,000 (14% of HP)	Any HE ≥16 mm pens at full damage	Any HE ≥16 mm pens at full damage. HE-spam target, and the section saturates fast (often only a few thousand HP).
Turret (module, per magazine)	separate HP pool, does not drain ship HP	3,700 magazine HP	Magazine detonation1–30% chance · below ~75% HP	Per-turret powder-magazine HP. Detonation chance scales from 1% (no mag damage) to 30% (full mag damage); this range is the in-game value. Detonation can't roll while the ship is above ~75% HP (the standard detonation-protection threshold, not a per-ship stat). Smaller magazines saturate to the 30% ceiling faster.
AA mount (76 mm mount)	separate HP pool, does not drain ship HP	200 per-mount HP	Destroyed at 0 HP	Per-mount HP for the heaviest AA on this ship. An AA mount destroyed at 0 HP stops shooting down planes for the rest of the battle; DCP does not repair destroyed mounts. HE shells specifically target AA mounts since the small-caliber HP pool falls fast.
Rudder (module)	separate HP pool, does not drain ship HP	4,300 module HP	Incapacitated at 0 HP	When module HP reaches 0 the rudder locks at its current angle until DCP repairs it. Repair via Damage Control Party.

Saturation cap = HP a section can absorb before further damage to it is reduced (the "bow-tank" effect). Citadel pool is ~165k on every ship (effectively no cap); damage is gated by pen/over-pen multipliers instead. Superstructure saturates fast but HE always pens regardless of the plate thickness. Rudder (and other module HPs) are a separate pool from ship HP: damaging a module doesn't drain ship HP. Incapacitated modules like the rudder and engine are restored by DCP, but secondary and AA mounts destroyed at 0 HP stay out for the rest of the battle.
