Quels problèmes l'IA navale du hotfix 1.13.7 de Victoria 3 corrige-t-elle ?

Le hotfix 1.13.7 de Victoria 3 (checksum f369) refond l'IA navale en profondeur : les flottes sont désormais composées par rôle (flotte principale de bataille + flottes de raid distinctes), les capitaux ne chassent plus les pirates, et plusieurs bugs d'invasion navale sont corrigés (abandon d'invasion sur état repris, refus de défense contre adversaire plus faible). Le PIB moyen de l'IA retrouve les niveaux de la 1.12, résumé par La Meute QC.

Qu'est-ce que le Canal de Kiel apporte dans le hotfix 1.13.7 de Victoria 3 ?

Le hotfix 1.13.7 de Victoria 3 rend le Canal de Kiel constructible, aux côtés de Suez et Panama. Les bordures de provinces du Sinaï ont été ajustées pour mieux suivre le tracé. En parallèle, la diplomatie permet désormais de négocier des traités avec des pays physiquement « hors de portée », débloquant des situations comme l'Espagne incapable de compléter l'Hispanoamérique faute d'accès au Paraguay.

Quels changements d'équilibrage naval le hotfix 1.13.7 de Victoria 3 apporte-t-il aux torpilleurs ?

Dans le hotfix 1.13.7 de Victoria 3, les torpilleurs deviennent les navires les plus rapides de leur époque — ils étaient les plus lents avant ce patch. La précision navale a aussi été revue : les tirs sont comparés à la vitesse et la visibilité de la cible, rendant les navires capitaux beaucoup moins précis contre les torpilleurs. Les péages ont été coupés de moitié avec un cooldown de 6 mois sur les changements.

Hotfix 1.13.7 — Naval AI overhaul and the Kiel Canal

Published on May 27, 2026•7 sections

HotfixAINavalEconomyjapon

The biggest 1.13 hotfix so far: over 100 entries centered on a naval AI overhaul (fleets composed by role, AI GDP back around 1.12 levels), a major naval balance pass (accuracy, torpedo craft, blockades), tolls cut in half, the Kiel Canal made constructable and a wave of Japanese content around the Ezo Republic. Checksum f369.

Key points

→Major naval AI overhaul — fleets composed by role, AI GDP back around 1.12
→Naval accuracy reworked — torpedo craft are now the fastest ships of their era
→Tolls cut in half + a 6-month cooldown on tolls and strait access
→Kiel Canal now constructable + treaties possible with 'unreachable' countries
→Large batch of Japanese content: Taikun system, Ezo Republic, Boshin War
→Checksum f369 — verify in multiplayer

The core of this hotfix. The AI now composes its fleets along defined roles: a main battle fleet that gathers most of the capital ships and stays much larger, and smaller fleets dedicated to raiding and piracy. Capital ships are no longer sent off chasing pirates, and each fleet focuses on missions that fit its composition. Paradox also did a major pass on fleet mission handling, in both war and peace. Several naval invasion bugs are fixed: the AI abandoning an invasion on a recaptured state, or flat-out refusing to defend itself against a weaker opponent because of incorrectly applied checks. Fleet mission areas are now capped based on fleet size. In their internal tests, average AI GDP returns to roughly 1.12 levels.

A big pass on naval accuracy. Hit chance is now compared against both the target's speed and visibility, and accuracy modifiers finally matter — capital ships will struggle to land hits on torpedo craft. Those torpedo craft also become the fastest ships of their era, when they used to be the slowest before this patch. For blockades, efficiency is now calculated as total strength divided by the actual resistance of blockaded states, instead of simply their count: a low-resistance state no longer eats up a large fraction of your blockade strength. Strength and resistance values were rebalanced to make blockades viable in the mid to late game. Utility modules also got a pass so each of them has a use.

Toll rates were excessive, especially with a single strait controller: they are slashed in half. A 6-month cooldown now applies to changing tolls and strait access, with a 7-day grace period to revert, just like tariffs and subventions. Paradox also busted a port embezzlement scheme: countries were paying inflated sums for port connection merchant marines. Shipping lane costs are now distributed proportionally to how much each market area actually buys from others. Merchant marine costs for connections and goods transfers were reduced, and countries are now forced to actually pay the merchants shipping their treaty goods.

FAQ

What naval AI problems does Victoria 3's hotfix 1.13.7 fix?

Victoria 3's hotfix 1.13.7 (checksum f369) deeply overhauls the naval AI: fleets are now composed by role (main battle fleet + separate raid fleets), capital ships no longer chase pirates, and several naval invasion bugs are fixed (invasion abandoned on a recaptured state, refusing to defend against a weaker opponent). Average AI GDP returns to 1.12 levels, summarized by La Meute QC.

What does the Kiel Canal add in Victoria 3's hotfix 1.13.7?

Victoria 3's hotfix 1.13.7 makes the Kiel Canal constructable, alongside Suez and Panama. Sinai province borders were adjusted to follow the canal's shape more closely. In parallel, diplomacy now allows negotiating treaties with countries that are physically 'unreachable', unblocking situations like Spain unable to complete Hispanoamerica because it couldn't reach Paraguay.

What naval balance changes does Victoria 3's hotfix 1.13.7 bring to torpedo craft?

In Victoria 3's hotfix 1.13.7, torpedo craft become the fastest ships of their era — they were the slowest before this patch. Naval accuracy was also reworked: hit chance is compared against the target's speed and visibility, making capital ships much less accurate against torpedo craft. Tolls were cut in half with a 6-month cooldown on changes.
