Styling Sci-Fi (and Fantasy) Ships & Spacecraft the CMOS 18 Way

Spaceships (and fantasy vessels) deserve the same formatting respect as historical vessels—whether they’re sleek starfighters, planet-hopping frigates, or galaxy-spanning warships. The Chicago Manual of Style (CMOS 18) helps keep ship names and classifications consistent.

Because let’s be real—an improperly styled Millennium Falcon or USS Enterprise can disrupt immersion faster than a hyperdrive malfunction.

Italicizing Sci-Fi Ship Names

✔ Full ship names are italicized – Millennium Falcon, USS Enterprise, Rocinante.
✔ Prefixes remain roman – USS Voyager, SS Heart of Gold, ISS Discovery.
✔ No quotation marks – Not "Serenity," but Serenity.

If Han Solo is bragging about the Millennium Falcon, you bet it needs italics. The prefix "USS" for Starfleet ships stays roman, just like naval vessels.

Prefixes & Sci-Fi Designations

Military & Fleet Ships:
✅ USS (United Star Ship / United Space Ship – Starfleet)
✅ IAV (Interstellar Alliance Vessel – Firefly)
✅ ISS (Interstellar Ship – common sci-fi use)

Civilian & Commercial Ships:
✅ SS (Space Ship – The Hitchhiker’s Guide to the Galaxy’s Heart of Gold)
✅ TS (Trade Ship – various sci-fi universes)

🚀 Example: USS Discovery (Not: “USS Discovery” or USS Discovery).

Referencing Ships in Sci-Fi Narratives

✔ Use “it,” not “she” – CMOS prefers neutral pronouns (The Rocinante sustained damage, but it kept flying).
✔ Lowercase generic mentions – The starship carried refugees.
✔ Historical or well-known ships follow standard rules – Serenity flew under radar, but the serenity of deep space stretched before them.

Sci-Fi Ship Classes & Types

✔ Do NOT italicize class names unless derived from proper nouns – the Nimitz-class carriers, the X-Wing-class fighters.
✔ Capitalize classes named after specific entities – Apollo-class explorer, but stealth-class corvette.

Example? The USS Enterprise is a Galaxy-class starship, but a general exploration-class vessel.

Hull Numbers & Designations in Sci-Fi

✔ Follow real-world naval formatting – USS Voyager (NCC-74656) conducted long-range scans.
✔ Keep identification numbers in roman text – NX-01 Enterprise, BB-63 Missouri.

Final Thought: Keeping Sci-Fi & Fantasy Ships Shipshape

Sci-fi and fantasy ships deserve accurate styling, whether they’re darting through asteroid fields or waging war across the stars. By applying CMOS 18 rules, you ensure clarity while keeping immersion intact.

Trusting Context and Order in Dialogue

How Readers Naturally Follow Conversations Without Excessive Tagging

Dialogue is the heartbeat of speculative fiction—it unveils personality, fuels tension, and moves the narrative forward. But too many dialogue tags (like he said, she replied) can bog down pacing and distract from what really matters: the exchange itself.

When context, voice, and rhythm work together, readers instinctively follow conversations without needing constant reminders about who's speaking. Speculative fiction thrives on immersive dialogue—where clarity comes not from tagging, but from trust in the reader’s ability to track the scene.

🔍 Why Context Strengthens Dialogue

• Clear character voices naturally signal who’s speaking.
• Logical turn-taking builds conversational rhythm.
• Strategic action beats clarify speakers without relying on repetitive tags.

Writers often worry that dialogue without attribution will confuse readers—but readers are smarter than we think. In scenes with two characters, the rhythm of back-and-forth is enough to guide them. Tags become necessary only when that rhythm breaks—such as when a third voice enters or an action interrupts the flow.

📖 The Fifth Season – Rhythm and Clarity Without Excessive Tags

N.K. Jemisin’s The Fifth Season offers a masterclass in subtle, context-driven dialogue. In scenes between Essun and Hoa, Jemisin minimizes attribution, relying on voice and pacing to signal who’s speaking:

"You should eat something."
"I'm not hungry."
"Still."

No “he said” or “she replied”—yet readers track each line effortlessly. The characters’ personalities, emotional subtext, and the order of exchange create momentum and clarity. Jemisin weaves in action and internal reflection to maintain rhythm without clutter.

Later scenes deepen this technique with layered emotions and unspoken tension, still keeping tags minimal:

"You don’t trust me yet."
"I barely know you."
"You barely know anyone anymore."

This kind of fluidity rewards close reading and amplifies emotional weight. It’s also genre-appropriate—speculative fiction often demands subtext and character-driven revelations that benefit from sparse tagging.

✏️ How to Strengthen Dialogue Without Tags

Let the structure do the heavy lifting:

• Distinct character voices
  If your telepath speaks in clipped, emotionless phrases and your smuggler favors sarcasm, you won’t need to tell us who said what—we’ll know.
• Dialogue placement as rhythm
  Alternating lines between two characters builds cadence and clarity. Disrupt only when the narrative needs it.
• Strategic action beats and internal thoughts
  A sigh, a glance at the sky, a shift in posture—these subtle cues anchor speakers without drawing attention to themselves.
• Reserve tags for disruption, not continuity
  Dialogue tags are scaffolding, not spotlight. Use them when rhythm breaks or clarity demands a nudge.

🧪 Writing Exercise – Dialogue Without Tags

Invite readers into the craft:

1️ Write a short dialogue between two characters—one human, one non-human (a stone eater, AI interface, interstellar diplomat, etc.).
2️ Limit yourself to one dialogue tag every six lines.
3️ Use personality-driven speech, action beats, and pacing cues to signal the speaker.
4️ Read it aloud: Does the rhythm and tone naturally identify who’s speaking without confusion?

Optional Bonus: Replace a tag with an internal reaction or sensory description to enrich atmosphere.

💬 Final Reflection

Mastering context-driven dialogue invites readers into conversations without holding their hand. Speculative fiction, more than any genre, welcomes this trust—it’s where alien minds, magical bonds, and revolutionary ideas unfold in voices that are distinct, compelling, and confident.

No need to say “she said” when the tone already says it all.
