Modern Warships Stealth Detection Guide

Update 0.107 changed how stealth works in ranked awareness — not just on stat sheets. Enemy ships and aircraft with the Stealth parameter now appear on your minimap as neutral circles when they sit outside direct view range. The circle confirms something stealthy is present; it does not reveal hull name, class icon, or heading until you re-detect the target by closing distance into view range or leveraging allied vision that satisfies detection rules.

Stealth upgrades are also removed from the module system — you cannot grind higher stealth through port upgrades anymore. Detection skill and team vision matter more than ever. This guide covers minimap habits, helicopter synergy, missile tactics under the new rules, and counter-play for subs and stealth frigates.

What changed in 0.107

Official Virtual Worlds notes specify:

• Stealth parameter no longer upgradeable — fixed per hull/loadout.
• Neutral minimap circles mark stealth contacts beyond your view range.
• Re-detection required to identify which enemy hides in the circle and which direction they face.

Reading neutral minimap circles

Think of circles as uncertainty zones, not free wallhacks:

Signal	Meaning
Circle near cap	Possible stealth DD/sub cap attempt
Circle behind island	Ambush lane — do not sail blind
Circle moving toward you	Close to re-detect before missile volley
Circle fading	Target lost stealth contact — still may be close

Bad habit: Ignoring circles because you cannot click a name.

Good habit: Route toward circle edge with helo or radar active, ready to flare.

Circles reward captains who already studied Maps wiki choke points — terrain that forces stealth hulls into narrow detection windows.

Re-detection — closing the identification gap

Re-detection means bringing the target into your view range (or equivalent spotting) so the minimap swaps from anonymous circle to identified icon with heading.

Practical steps:

1. Slow approach from cover — Burst speed alerts stealth subs; creep with sonar-active frigates if equipped.
2. Angle radar — Island breaks line of sight; reposition for a peek before committing guns.
3. Coordinate ally spotting — Allied radar contact can maintain experimental missile locks in 0.107; it may also help team identification depending on mode rules — watch official tooltips after maintenance.
4. Do not overextend alone — Circles bait solo destroyers into crossfires. Ping team before chasing.

Submarine mains playing ROKS Jang Yeong-sil or legacy stealth subs should assume circles expose their general cap lane — vary approach timing.

Helicopter spotting synergy

Helicopters remain the strongest counter to stealth on island maps:

• Launch before entering cap radius — Spotters turn circles into identified targets earlier.
• Orbit cap approaches — Loop flight paths over likely sub lanes between islands.
• Protect the helo — AA frigates shoot down spotters; escort or swap to gun defense when enemy F125-style buffs land post-rebalance.

Read How to Play for aircraft control basics and Missile and Flare Tactics for engaging once identification completes.

Destroyer captains: if your build mounts Z-19E from the August Battle Pass shop, integrate helo time into every ranked push — see Battle Pass Guide.

Missile tactics under stealth circles

Stealth circles do not block missile locks once identified — but 0.107 adds experimental lock through obstacles on select batteries while radar detection persists. Key distinctions:

• Circle ≠ identified target — Some weapons need full ID before firing solutions stabilize.
• Lock through terrain ≠ terrain immunity — Missiles can still hit islands mid-flight; see Virtual Worlds notes.
• Flare bait still works — Stealth does not negate decoys after identification.

Missile destroyers should practice identify-then-volley drills in custom rooms: spot circle → re-detect → single-salvo test before ranked.

Counter-play by class

Destroyer / frigate

• Hold island edge until circle resolves.
• Bring CIWS online before chasing into narrow passes.
• Post-rebalance FGS F125 view range buff helps re-detection — check Frigate Tier List.

Cruiser / battleship

• Never cap alone into active circles.
• Use main battery range only after ally spot confirms class — avoid wasting reload on submerged ghosts.

Submarine

• Assume your stealth generates circles for enemies — vary depth routes.
• Strike after ally recon identifies targets for team volleys.

Carrier / aviation

• Fighters extend identification range over caps.
• Strike stealth circles only with confirmed spot — torpedo bombers waste payloads on false approaches.

Training routine (15 minutes)

1. Custom room on island map.
2. Note circle spawn when stealth bot hides behind terrain.
3. Launch helo → observe ID transition.
4. Fire one missile salvo — watch terrain collision if using experimental battery.
5. Repeat with flare bait on incoming stealth DD.
