Sfs Nuke Blueprint [best] Jun 2026

Arrange a primary hollow fairing structure.

Many players refer to the Ion Engine as the "electric nuke" of SFS. While it uses electricity and liquid fuel rather than uranium, it fits the profile of a low-thrust, extremely high-efficiency engine. At a size of just 2x1 units, the Ion Engine is the smallest-footprint engine in the game. It is perfect for probes and small interplanetary craft once you are in a vacuum.

In , a "nuke" blueprint typically refers to player-created, non-functional military designs that simulate the appearance or destructive impact of a nuclear weapon using clever game physics. Popular Design Approaches

I can provide step-by-step file code templates or specific parts layouts based on your preferences.

Tap on the main settings menu button, select the "Download Blueprint" option, paste the direct URL string (e.g., sharing.spaceflightsimulator.app/rocket/... ), and confirm. The rocket will import and render on your building grid within seconds.

Place a side-separation piece or a docking port inside to act as the release mechanism for the payload. 3. Engineering the "Core" To build the actual destructive core inside the fairing:

Their legendary creation, the , was developed by a member named DoomSkull. Even though he had never played the game before, DoomSkull, who has a strong programming background, was approached by another member, Heroix, about automating the writing of BPs (blueprints) to create a "nuke." After a brief explanation, he wrote a script that created what is still considered one of the best nukes ever made in the game.

Blueprint editing has given birth to many of the most impressive creations in Spaceflight Simulator , of which the "nuke" is just one example:

The platform orbits at 150 km. To bombard a surface target, detach a drone, perform a de-orbit burn using its RCS, and let it slam into the target at terminal velocity (~1,100 m/s). The mothership repositions using Ion engines.

You can find detailed steps on Blueprint Editing on the official Wiki. 3. High-Velocity Impacts

| Component | Quantity | Purpose | |-----------|----------|---------| | Nuclear Engine | 1–4 | Primary propulsion (e.g., Valiant or modded NERVA ) | | Large Liquid Fuel Tanks | 4–6 | Fuel storage (no oxidizer) | | Structural Struts | 2–4 | Secure engine cluster to fuel tank | | Probe Core | 1 | Flight control | | Radiators (Modded) | 2+ | Dissipate heat (if using realism mods) | | Decoupler | 1 | Separate from launch vehicle |

First, a critical clarification: Spaceflight Simulator has no built-in nuclear explosion mechanic. The game models orbital mechanics, atmospheric drag, and collision, but not radiation or blast effects. When the community searches for "SFS nuke blueprint," they are typically looking for:

| Component | Vanilla SFS Nuke Blueprint | Modded SFS Blueprint | |-------------------|---------------------------------------|-------------------------------------| | Engine | 3x Valiant (vacuum optimized) | 1x Nuclear Thermal Rocket (NTR) | | Propellant | 2x Large fuel tanks (Hydrogen analog) | 4x Cryogenic tanks | | Warhead (kinetic) | 1x Structural Fuselage + 6x large tanks | 1x 12m fuel tank (resized) | | Guidance | Probe core + 4x RCS | Smart Parts Mod (programmable) | | Impact speed | 1,800–2,500 m/s | 5,000–10,000 m/s (with modded engines) |
