Hello from the Triassic Games team!

Sea Power is on sale as part of the Steam Autumn Sale beginning today, running through October 8th!

In addition, we have updated Sea Power to v0.8.3 today. This update brings more variation and continuity to Pacific Strike campaign, new ways to arrange your map and issue standing orders, major changes to how ships respond to threats and use their guns, and a substantial collection of new units, weapons, tools, and fixes.

Here are the main highlights:

Please note: Update 0.8.3 is not the Royal Navy update. The Royal Navy and Argentina content, together with the Falklands campaign, are being prepared for a separate release. We have an update on that schedule below.

A Changing Enemy Theater in Pacific Strike

Pacific Strike now uses Dynamic Unit Generation across its missions. Instead of every supporting enemy force being fixed in advance, the campaign can select escorts, coastal forces, aircraft, and other units from a theater roster when a mission begins. Key named ships that are part of the campaign story remain in place.

The new Situation tab lets you review what is known about enemy forces in the theater. It records units you have encountered and those you have destroyed, so the picture develops as you progress. An enemy unit that survives an encounter may appear again later. This should make each campaign run less predictable while giving your actions more continuity from one mission to the next.

Pacific Strike remains a Task Force Mode campaign with linked missions; this change adds variation and persistent enemy-force tracking within that structure. Note: if you are a campaign builder and interested in using the Dynamic Unit Generation system, please review the guide here.

The Situation tab accessible from the bottom bar will now show the known enemy forces in the theater. Losses are tallied, recorded, and shown to the player whenever requested. Units destroyed in the early missions will not reappear later on.

Campaign Setup Window Overhaul

V0.8.3 introduces a change in how Task Force Mode campaigns are launched - instead of assigning Commanders inside the campaign, Commander setup is now done pre-launch, as part of an overhaul of the campaign setup window:

Setup your Commander and choose your difficulty settings before campaign launch. This is part of an overhaul for the campaign UI that will later support Dynamic Campaigns.

Picture in Picture and Multi-Monitor Phase 1

You can now press Tab to expand the tactical map while keeping the 3D view in a smaller picture in picture window. It is a way to give the map more space without losing sight of the action. The previous map-only behavior remains available as an option.

Update 0.8.3 also introduces the first phase of multi-monitor support. If you have a second display, you can place the 3D view there while keeping the map and game interface on your primary display. This is an early feature with a specific scope: full multi-monitor support is planned for a later update.

To enable Picture-in-Picture, just hit Tab to expand the tactical map.

Hit Tab to expand the map to full screen, and by default the 3D view will appear as a Picture-in-Picture mode. Use the map options at top right (hamburger menu) to enable or disable "World View" as Picture-in-Picture.

Enabling World View on Another Monitor

To enable World View on another monitor, navigate to Options > Video and then scroll down to find World view monitor settings. Note that only the 3D view can be moved at this time. Full multi-monitor support is planned for later on.

Standing Orders and Formation Manager Updates

The new Standing Orders panel gives you a more direct way to control how your forces behave without repeating the same orders for every unit. This capability was formerly known as the Doctrine Panel.

You can set orders for your force as a whole, then make exceptions for a formation or an individual unit. Formation and unit settings override the global setting where needed. Global orders can be saved to your profile, while formation and unit orders are saved with the mission.

The panel brings several existing behavior controls into one place and adds more choices, including how ships respond to hostile aircraft and whether they use anti-ship missiles under Weapons Free. We have also updated the Formation Manager with separate tabs for ships, aircraft, submarines, and other unit categories, along with the ability to reorder groups and retain that order when saving.

Standing Orders panel now allows more granular control over unit behavior.

Threat Response and Electronic Warfare

Update 0.8.3 introduces an OODA loop system for how units observe, assess, and respond to threats. When it is enabled, a ship’s combat system matters beyond the weapons and sensors it carries. Reaction time, the number of contacts its combat information center can work on, and the number it can evaluate at once all affect how it handles a busy tactical picture. Datalinks can also help ships share that work within a formation.

The effect is most apparent in air defense: a force facing several simultaneous contacts has to detect and process them before it can respond effectively. Different generations of combat systems should feel different under that pressure.

Electronic warfare has also been rebalanced. Offensive jamming now depends more on range and radar burn-through, while chaff and missile countermeasures better reflect differences in equipment and era. A jammer can remain useful at long range without simply making an opposing radar blind. We have also added defensive noise jamming and revised how missiles resist jamming and deception.

These systems involve a great deal of tuning, and we expect to keep refining their balance with feedback and testing.

The new Status panel for each unit consolidates its OODA info, Flight Deck, Damage Control, and Sensors UI into one clean panel. The OODA loop can be observed from the Engagement tab. As contacts are processed, they move along the board until action is taken against them.

Gunnery Overhaul

Gunfire has received one of the largest simulation changes in this update. Surface gunnery now depends more directly on the quality of the fire-control system, the accuracy of the mount, and the crew’s ability to build and correct a firing solution. More capable directors can establish an accurate solution quickly; older or simpler systems may need time and observed fall of shot to bracket a target.

CIWS has changed as well. Bursts are simulated with projectile flight and accuracy rather than a single abstract interception result. Reaction, tracking, burst length, and the physical performance of the system all contribute to whether it can stop an incoming weapon.

Visibility matters more throughout these changes. Optical fire control is less effective at night without suitable equipment, and aircraft attacking in darkness or poor conditions face more meaningful limitations. Bombing accuracy has also been revised to distinguish the capabilities of different aircraft and their bombing systems.

We will continue tuning individual mounts, fire-control systems, and weapons after release.

New Units and Weapons

There are many new and revised units in 0.8.3. Two of the largest additions are the VLS Ticonderoga-class cruiser and VLS Spruance-class destroyer, bringing their vertical-launch configurations to the game alongside the weapons and loadout work needed to support them.

Other additions include:

Pacific Strike’s available forces have been updated to include the new JMSDF destroyers. Many existing ships, aircraft, sensors, and loadouts have also been revised to better represent their equipment at different dates.

Mission Editor Improvements: Air Operations & Others

Scenario creators now have an Air Operations tab for setting up scheduled aircraft routes through the Mission Editor. It brings the existing route system into the interface, with visible waypoints and controls for speed, altitude, sensors, rules of engagement, attacks, refueling, and return to base.

Waypoints can be placed relative to another unit, allowing a CAP or AEW station to move with a task force. The editor also checks a route against the aircraft’s estimated fuel range and warns when the next waypoint may be unreachable. Routes can start disabled and be activated or changed through triggers.

The Mission Editor also adds several tools for building scenarios:

Other additions and improvements include:

Royal Navy and Falklands

V0.8.3 is a core game update, not the Royal Navy release. Work continues on the Royal Navy and Argentina factions and the South Atlantic 1982 Falklands campaign as a separate content package.

We are currently targeting the end of October or early November for that release, subject to final testing. We will share more of the ships, aircraft, campaign, and scenarios as the package approaches release.

Thank you for your continued support of Sea Power. We hope you enjoy exploring everything in Update 0.8.3.
