Top Freeware Stealth & Thrust-Vector Mods for DCS World.

Top Freeware Stealth & Thrust-Vector Mods for
DCS World.
(F-22, F-35, YF-23, Black Widow, SU-47)

Introduction’

One of the most compelling parts of the DCS World community is the creativity and dedication of modders. Over the years, several freeware stealth / advanced aircraft mods have gained wide interest, letting sim pilots fly “what-if” or prototype jets with stealth, thrust vectoring, and experimental features.

Below, I present a curated list of the more mature or promising mods (as of 2025), with history, features, caveats, and download links.

A few important caveats before we dive in:

• Many mods are single-player only or may break your multiplayer compatibility or integrity checks.
• Some mods depend on FC3 (Flaming Cliffs 3) or other base modules; others are more standalone.
• Always keep a separate “mod bench” or “inactive mods” folder so you can disable risky mods when joining multiplayer servers.
• Because these are community efforts, specs and capabilities may vary and are often approximate or “best guess” rather than rigorously tested.

Below I separate by stealth / prototype mods you mentioned, then wrap up with general discussion about stealth, thrust vectoring, and operational considerations in DCS.

1. Grinnelli Designs F-22A Raptor (Community Mod)

History & Modder

• The Grinnelli Designs F-22A mod is one of the most well-known and long-standing freeware DCS mods. (grinnellidesigns.com)
• The mod has an open GitHub repo (GPL-3.0) with source code and release versions. (GitHub)
• It is not an official module; it is maintained by the community.
• Because it depends on F-15C / FC3 avionics systems, it is not completely standalone. (GitHub)

Features & Specs

• Uses a Simple Flight Model (SFM) rather than a full EFM, though later versions may push toward more complexity. (grinnellidesigns.com)
• Six degrees of freedom (“6-dof”) cockpit, clickable controls, PBR textures, multiple MFD pages, interactive instruments. (grinnellidesigns.com)
• The mod’s version 3.0 added fixes for compatibility with recent DCS patches (overwing vapor, collision model, gear sinking, etc.). (grinnellidesigns.com)
• There is a community “unofficial update v1.2” patch that tweaks fuel, radar detection, “supercruise” behavior, and weapon placements. (digitalcombatsimulator.com)
• Because the mod piggybacks on FC3’s F-15C framework, its aerodynamic limits, drag, etc., are constrained by what is permissible via that framework. (GitHub)

Download / Link:

• Primary mod page: GrinnelliDesigns F-22A (grinnellidesigns.com)
• GitHub source: grinnellidesigns/f-22a (GitHub)
• Unofficial patch v1.2: via DCS.com user files (search “F-22A Raptor unofficial update v1.2”) (digitalcombatsimulator.com)

Standalone vs FC3 Dependency

• Dependency: It requires FC3 / F-15C support for avionics and core systems. (grinnellidesigns.com)
• Not standalone in the strictest sense, though the mod is self-contained in a folder.
• Because of the dependency, it may fail integrity checks or break multiplayer compatibility if used improperly.

2. VSN F-35A / F-35 Community Mod (VSN)

History & Modder

• The VSN F-35 (Lightning II) community mod aims to implement the F-35 (A, B, C) in DCS. (ED Forums)
• The mod is free, with clickable cockpit, custom systems, and STOVL / VTOL functionality for B variant planned. (ED Forums)
• The mod team intended the mod to be standalone (i.e. not requiring paid modules) initially using VSN models and borrowed systems from FC3 modules for initial builds. (ED Forums)
• Later update patches (e.g. by Civorodom) extended weapon compatibility (e.g. Gripen mod weapons) and engine sounds. (digitalcombatsimulator.com)

Features & Specs (as implemented / claimed)

• Clickable cockpit with instrument systems. (ED Forums)
• STOVL / VTOL behavior (at least in mod preview) for F-35B. (ED Forums)
• Uses custom flight modeling within DCS mod APIs. (ED Forums)

Download / Link:

• Forum thread / mod page: F-35 A/B/C Community Mod by Tangent / Speedracer (ED Forums)
• Demo / tutorial: F-35 Lightning II Mod: How To Download, Install & Operate (VSN) (YouTube) (YouTube)
• Update patch (VSN F-35 by Civorodom): weapons / sound extensions (digitalcombatsimulator.com)

Standalone vs FC3 Dependency

• The original design aimed to be standalone, not requiring FC3 or paid modules. (ED Forums)
• However, in user discussions, some report needing FC3 or F-15C (or other dependencies) for certain functionality or to satisfy script dependencies. (ED Forums)
• In short: somewhat ambiguous in community; some versions may impose dependencies.

Caveats & Community Feedback

• Some users report download links have died or are hard to access. (ED Forums)
• Others mention that when loaded, the cockpit may show FC3 / F-15 components (i.e. reuse) which can reduce immersion. (ED Forums)
• As with any advanced mod, stability, accuracy, and multiplayer compatibility are not guaranteed.

3. YF-23 / “Black Widow / Black Widow II” Mod Projects.

History & Modder

• There have been multiple community attempts to build a YF-23 / “Black Widow” mod (sometimes called Black Widow II) using unclassified manuals and prototype data. (ED Forums)
• The mod author “cubanace” had posted about a YF-23A internal cockpit modeling effort as early as 2017. (ED Forums)
• Community posts in forums indicate that multiple versions exist or have existed, but none seem to be in wide, stable release. (ED Forums)

Features & Claims

• Prototype / speculative model with F-15-derived cockpit HUD in some versions. (ED Forums)
• Some functionality (longitudinal missile lock) reportedly works, but animations and systems are incomplete. (ED Forums)

Download / Link:

• Forum discussion: “Link for the YF-23 Black Widow mod?” (ED Forums)
• YF-23A project thread by cubanace (ED Forums)

Standalone vs FC3 Dependency

• According to early project posts, the YF-23 mod was intended to be built with a custom flight / systems model (EFM + ASM) and not dependent on FC3. (ED Forums)
• But because many mod attempts are partial or experimental, some forks or versions may impose dependencies or reuse existing modules.

Caveats

• As of 2025, the YF-23 mod remains somewhat experimental; download links may be broken or projects abandoned.
• Many community posts express frustration at lack of completeness (missing animations, partial systems) (ED Forums)

4. SU-47K / “Berkut / Firkin” Mod

History & Modder

• The Su-47K Berkut / Firkin mod is one of the more mature “exotic” Russian experimental aircraft mods hosted in DCS user files. (digitalcombatsimulator.com)
• The mod has seen multiple updates (v2.5 at least) and bug fixes. (digitalcombatsimulator.com)
• The author(s) include “AlexTv” among others. (digitalcombatsimulator.com)

Features & Specs

• Forward-swept wings, internal weapon bays, carrier landing capability (in some versions), drag chute, air-to-air & air-to-ground capability claimed. (digitalcombatsimulator.com)
• Visual pilot model, animated avionics, various liveries. (digitalcombatsimulator.com)
• Bug fixes: collision issues, missile explosion in bay, landing issues, input fixes. (digitalcombatsimulator.com)
• Because the mod is ambitious, some features are still works in progress or imperfect (e.g. damage model, full cockpit visuals). (digitalcombatsimulator.com)

Download / Link:

• Su-47K Firkin / Cy-47K Berkut Mod v2.5 on DCS user files. (digitalcombatsimulator.com)
• Earlier v1.0 version description also available (less mature). (digitalcombatsimulator.com)
• Mod demo / flight videos: YouTube “Su-47 Berkut mod demo / flight” etc. (YouTube)

Standalone vs FC3 Dependency

• The mod requires FC3 DLC (for core systems) and Su-30 module by Codename Flanker for some rocket support. (digitalcombatsimulator.com)
• So it is not standalone; it relies on FC3 infrastructure for many systems. (digitalcombatsimulator.com)

5. Black Widow / “Black Widow II” – Sometimes conflated with YF-23.

• Some mod versions or community builds are marketed under Black Widow II (e.g. Growling Sidewinder’s video mention) rather than strictly YF-23. (ED Forums)
• These are often variant forks of YF-23 projects, possibly combining other assets.
• Because their lineage and stability vary, I treat them as variants of the YF-23 / prototype mod family rather than a separate stable mod.

Quick Comparison Table.

Using Mods in Single Player vs Multiplayer.

Single Player Use

• Using mods in single-player is generally safer: you can fly them in your own missions, tests, dogfights, training, etc.
• You can push boundaries, experiment with configurations, enable verbose logging or debug variants.
• You control what is active, so you can isolate mod crashes from game corruption.

Multiplayer / Online Use

• Integrity checks: Many multiplayer servers enforce module integrity checks or whitelist modules. If your modded files deviate, you may be banned or disconnected.
• Balance concerns: Mods may provide unfair advantages (supercruise, better stealth, overpowered weapons), so server admins may disqualify them.
• Version mismatch: If your mod version differs from others or the “official” baseline, it can desync or crash sessions.
• Conflicts: Mods might conflict with official modules, shared scripts, or mission logic.

Best Practice: Maintain a separate “Mods_Inactive” or “OfflineMods” folder. When joining multiplayer, move all non-approved mods out of the active SavedGames\DCS\Mods\aircraft\ folder. This allows a “clean” baseline for multiplayer.

Stealth, Thrust Vectoring & Modern Weapons Systems (in Mod Context)

Stealth / Low Observability (LO) Considerations

• In real life, stealth is not invisible — it’s low observable, reducing radar cross section (RCS), IR, and other signatures.
• In DCS mod context, you’ll often see stealth simulated by reduced radar detection ranges, narrow fields of view, or conditional detection (e.g. seen only when above clutter thresholds).
• Many mods approximate stealth via sensor fusion, ECCM scripting, and “radar detection thresholds” rather than truly simulating physics.

Thrust Vectoring & Manoeuvrability

• Thrust vectoring (TVC) allows control of the thrust nozzle direction (pitch, yaw) to augment control surfaces, especially at low airspeeds or high angles of attack.
• In DCS mods, TVC may be simulated via custom scripting (modifying forces) or via engine control logic.
• Some community mods attempt to add TVC (e.g. F-22 mod forums mention combining F-22 with thrust vectoring mod). (ED Forums)
• Be cautious: adding TVC can destabilize the flight model if not balanced, producing crashes or unrealistic behavior.

Modern Weapons Systems.

• A big challenge for 5th gen / advanced mod development is the sensor-weapon integration:
  • BVR missiles like AIM-120D, AIM-260, Meteor, etc.
  • Multimode radar (pulse-Doppler, ISAR, SAR, ground mapping).
  • Electronic warfare, ECM, decoys, countermeasures.
  • Sensor fusion, datalink (e.g. sharing radar tracks, cooperative engagement).
  • Internal weapon bay logic vs external pylon logic (stealth tradeoffs).
• Many mods currently rely on simplified missile scripts or reuse weapons logic from base modules.
• For example, the extension patch for VSN F-35 (Civorodom) enables the mod to carry weapons from the Gripen mod (AIM-132, Python-5, Meteor, etc.). (digitalcombatsimulator.com)
• Another example: JSN64’s “F-35 Extended weapons submod” extends VSN F-35 to carry more weapons (SPEAR-3, GBU-39, etc.). (digitalcombatsimulator.com)

Final Thoughts & Recommendations.

• These mods are fantastic proof-of-concept, creative, and fun to fly in single-player or controlled environments.
• For serious multiplayer use, proceed cautiously always test mods in offline environments and disable them when connecting to public servers.
• When installing, keep backups and forestall file collisions (e.g. by isolating mods).
• Because mod stability, compatibility, and accuracy vary greatly, treat their performance specs with caution they are approximate and subject to changes by updates or patches.
• The community is your best guide: check forums, modder Discord servers, changelogs, and user feedback before trusting a mod.
