Thu, May 28, 2026



Early Access Update #1

Modern Naval Warfare has finally launched into Early Access. First off, thanks everyone for the constructive feedback, which shows us you care and you want this simulation to succeed as much as we want it to.

As stated in our Early Access questionnaire, there are a number of items that you are flagging as core issues that are part of our roadmap to 1.0

We are working on an official roadmap that we will share with you as soon as we have stabilized a set of immediate fixes, but rest assured, we are looking at supporting the simulation in the very long term, and listening to your feedback and working on the changes you highlighted is our immediate priority.

Below are a set of items we are actively working on:

1. Performance & Optimization

We are actively hunting down memory leaks and optimization bottlenecks based on your feedback. Our team is refining multi-core CPU and GPU utilization to stabilize frame rates across all systems.

Please continue sending crash logs, system specs, and bug reports to our support team. This data is invaluable for targeting specific hardware conflicts.

2. Tactical & Operational AI changes

The AI currently executes baseline reactive behaviors, but it needs to be more dynamic and aggressive.

Short-Term: We are upgrading AI maneuvering so enemy hulls actively use thermal layers and ambient weather for cover, while coordinating massed missile salvos to overwhelm your defenses.

Long-Term (Operational): We are designing a mission-wide theater commander system to automatically coordinate friendly and enemy forces across the entire map.

3. UI/UX & Quality of Life

We are restructuring the user interface based on community and influencer feedback. This includes layout ergonomics, contrast fixes on tactical screens, and the introduction of crew voice-overs to enhance immersion.

4. Documentation & Station-Specific Videos

To smooth out the learning curve, we are expanding our documentation with manuals detailing the precise operational differences between various submarine blocks.

Crucially, video tutorials will soon be accessible directly from each station. If you are struggling with TMA or Sonar, a single click on that station will launch an in-depth video guide explaining exactly how to operate it.

5. Localization

Localization is planned to be included in future updates. We are targeting German, French, Spanish, Russian, and Simplified Chinese as first languages


Moving Forward

The simulation genre demands precision, and we have the tools and the plan to deliver it.
Expect a steady stream of targeted updates rolling out shortly, beginning with core optimization and expanding into AI and UI improvements.

We plan to deliver the first update in the second half of June.

Modern Naval Warfare - Early Access Update #2
Thu, 11 June 2026



Following our launch into Early Access, we want to thank everyone for the continuous stream of constructive feedback.

In our previous update, we stated our plan to deliver the first technical update in the second half of June. We are still planning to do so, but wanted to push a hotfix to address some of the biggest issues from release.

This update addresses several game-breaking stability issues, refines core simulation systems, and introduces initial UI/UX improvements based directly on your feedback.

Below is the complete list of fixes and features included in today's build:

Fixed Issues

    Critical Stability & Logic:

•         Fixed a game-breaking error (NullReferenceException) that occurred during certain actions in Blocks 1 & 2 when utilizing the TMARuler.
•         Fixed a critical crash triggered when the submarine surfaced with the snorkel raised before completely breaking the surface.
•         Resolved an issue where training torpedoes would remain stationary and unresponsive in the water after being fired.
•         Optimized production builds by removing unwanted internal testing components (such as SSH clients).
•     Mission & Simulation Corrections:
•         Fixed multiple bugs causing the player to spawn at incorrect depths during Quick Mission setup.
•         Corrected objective triggers to properly differentiate between primary and secondary objectives, and fixed target hit registration issues on Mission 1.

    Sensors & Visuals:

•         Fixed over-the-horizon visual calculation issues regarding earth curvature viewing for ship hull rendering and Photonics "Mono" camera extreme range visibility.
•         Verified and restored proper sonar operations on Block 4, and corrected the waterfall component setup for the DEMON display on Blocks 1, 2, and 4.

    UI/UX & Audio:

•         Added selectable depth alarms to the pilot auxiliary displays to enhance station awareness.
•         Fixed audio logic to stop the Active Intercept chirp sound from playing continuously when signals are stale.

Known Issues

We are actively tracking the following verified issues and working on solutions for our upcoming updates:

•     Submarine Steering: In certain scenarios, after multiple attempts to follow a plotted course, the sub can become stuck on a heading that cannot be changed.
•     Autopilot & ECDIS: Deleting a route while the autopilot is active can temporarily lock you out of course changes. Entering specific values in the ECDIS coordinates field can cause it to become unresponsive.
•     Audio/Visual: Radar mast 3D models might not visually appear raised on Blocks 1, 2, and 4 (the radar functionality itself remains active). Explosion sounds are currently not registering on Sonar displays.

Moving Forward

Our commitment to expanding Modern Naval Warfare remains our top priority. We are continuously monitoring your feedback as we polish core features and move forward towards release.

Please keep sharing your logs, system specs, and bug reports on our official forums and Discord.

Systems & Performance Update
Tue, July 7, 2026



Following our continuous work on expanding and perfecting the simulation, we want to thank everyone for your incredible dedication and the steady stream of constructive feedback.

Our team has been working tirelessly behind the scenes on a massive technical overhaul. In this Systems & Performance Update, we are thrilled to announce that Modern Naval Warfare has officially migrated to Unity 6.3 LTS, introducing a DirectX 12 baseline, support for Raytracing graphics effects, and modern upscaling features like DLSS and FSR. Furthermore, we are expanding our global reach by introducing official localization support for six new languages.

This update also overhauls core weapon control logic, refactors submarine mast exposure physics, and fixes a critical VRAM leak to heavily optimize performance during long play sessions.

Below is the complete list of fixes, features, and known issues included in today's build (0.118.:


Fixed Issues

Engine, Performance & Graphics

• Unity 6 Migration: Successfully migrated the project to Unity 6.3 LTS, establishing DX12 as the base for Windows (retaining DX11 compatibility) and enabling ultra-quality Raytracing effects.
• Upscaler Support: Added integrated support for modern upscaling technologies, including NVIDIA DLSS and AMD FSR.
• VRAM Optimization: Fixed a critical VRAM leak caused by rogue assets not unloading upon mission completion, drastically improving stability during long sessions.
• Cinemachine Upgrade: Migrated Cinemachine to a fully Unity 6 compatible package.

Features & Localization

• Expanded Language Support: Added official localization for English, German, French, Polish, Chinese, and Russian.
• New Settings Options: Added toggles for Motion Blur, Underwater Blur, and a new setting to customize the transition speed between stations.
• Input & Camera Controls: Migrated to the new Unity Input Manager and added options to invert the mouse Y-look axis (including specific controls for Photonics view).
• User Data Migration: Implemented updated user migration mechanisms (MSV 0.117.0 / 0.118.0) to safely inject new settings without breaking older user profiles or save files.
• Simulation & Weapon Control Overhaul
• Advanced Weapon Control: Overhauled weapon depth/altitude control logic utilizing real-world PID systems, making torpedoes and guided systems significantly more accurate and lethal.
• Mast Exposure Physics: Refactored the mast controller system to correct exposure tracking above water, fixing a serious issue where sensors malfunctioned at periscope depth or enemies failed to detect exposed masts.
• Radar Mesh Improvements: Added new cached submarine meshes to vastly improve radar cross-section (RCS) detection of masts exposed over the water line.
• Environmental Data (SSP): Introduced realistic seasonal GIS data interpolation and day-to-day temperature deviations, creating dynamic monthly ocean variations.
• Advanced Radar Calculations: Improved Pulse Radar Line of Sight calculations using true earth curvature and optimized RCS tracking by factoring reflection areas against pulse wavelengths.

General Bug Fixes

• Autopilot & Steering: Resolved a major issue where deleting a plotted route while the Autopilot was active would lock the system and ignore subsequent steering orders.
• Navigation & UI: Fixed an issue where entering specific coordinate values in the ECDIS field rendered it unresponsive, and restored mouse scroll wheel functionality in the time compression UI area.
• Sensor Fixes: Resolved a critical bug in the Aperture Calculator that caused sensors and NPCs to become unresponsive upon entering the Salma H mission. Fixed uncleaned station UI texts that caused blurry lettering when focusing.
• Communications & Radar: Corrected radio antenna water exposure calculations that hindered underwater communications, and fixed a sync issue that delayed or prevented terrain rendering on the Radar screen.
• Data Corrections: Fixed general AIS bugs where speeds were not correctly converted to knots, updated Torpedo status mapping methods to Enum, and formatted ESM values clearly into GHz.

Known Issues

• We are actively tracking the following verified issues and are working on solutions for upcoming patches:
• UI & Sonar: Active Intercept can register the same contact multiple times if the contact operates on a very low Pulse Repetition Frequency (PRF). HF Sonar Bearing/Range numbers are temporarily missing, and explosion sounds are currently not registering on SONAR displays.
• Visuals & Customization: Ship names currently do not print on hulls during gameplay due to a name-assigner shader issue, and names may fail to assign properly after loading a save.
• Upscaler Artifacts: Setting upscalers (DLSS/FSR) to high-performance modes can cause station UI text to appear slightly blurry.
• Physics & Anomalies: We are monitoring a rare, low-frequency physics loop-breaking issue causing visual anomalies ("flying whales"), though it is expected to be largely resolved.
• Upcoming Languages: Work is ongoing to complete official localization support for Spanish, Greek, and Romanian in a future update.
