How to name a classified experiment credibly
Real black projects (MK-Ultra, Manhattan, Stargate, Bluebird, Iron Mountain) share detectable patterns: an evocative word that doesn't describe content. Manhattan has nothing to do with atomic bombs; the project was named that way because initial HQ was in Manhattan. This functional opacity is key: the name shouldn't betray purpose.
Military codename technique uses dictionary words unrelated to the operation. Real DoD generators randomly pick from curated lists. If your lab studies mind control, calling it 'Mind Control Project' is absurd; calling it 'Project Bluebird' or 'MK-Ultra' is historical. The rule: the prettier, neutral or poetic, the more sinister retrospectively.
Add phase and sub-project. MK-Ultra had subprojects 1, 2, 47, 119. Each with different focus under larger umbrella. Your fictional program can have Sub-Project 23 for hypnosis and Sub-Project 47 for drugs, both under Project Atlas. That hierarchical structure multiplies narrative possibilities.
Experiment types by narrative genre
Mind / psychological control: codenames inspired by MK-Ultra (Bluebird, Artichoke, Spellbinder). Your program can use drugs, hypnosis, sensory deprivation. Stranger Things's MKUltra and The Bourne Identity's Treadstone fit here. The aesthetic is Cold War, clandestine psychiatric hospital, subjects without consent.
Bio-genetic: organic codenames (Chimera, Helix, Genesis, Hydra). The experiment creates hybrids, modifies humans, manages pandemics. Resident Evil's T-Project and G-Virus, Splice's NERD. The aesthetic is contaminated biological lab, embryos in tubes, transforming subjects.
Exotic energy and weapons: mineral or astronomy codenames (Trinity, Quartz, Polaris, Argon). The experiment involves nuclear, laser, plasma weapons, quantum travel. Manhattan Project, Project Pluto, Project Orion (both real). The aesthetic is remote desert, underground bunker, anti-radiation gear.
Paranormal and dimensional: poetic codenames (Stargate, Ghost, Looking Glass, Mirage). The experiment explores remote viewing, astral travel, entity contact. Stranger Things's Indigo, Hickman's The Manhattan Projects. The aesthetic is isolation room, sensors, subject with wires.
Common mistakes inventing codenames
Mistake 1: too descriptive name. 'Project Mind Control' or 'Operation Werewolf Soldier' breaks codename logic. The essence of classified names is surface innocuousness. Amateur series choose pulp names (Project Skeleton King); professionals choose innocent words that turn sinister only after knowing what they did.
Mistake 2: ignoring time span. Real projects last decades. MK-Ultra started in 1953 and extended to 1973. Your fictional program should have start date, milestones and possibly an official closure followed by covert continuation. That chronology allows sub-phases with different codenames: 'the program changed from Bluebird to Artichoke in 1955'.
Mistake 3: a single subject. Real experiments usually have cohorts of 50, 200, 1000 subjects. Your fictional program can have a protagonistic one, but others must be mentioned, failed or successful. Stranger Things has Eleven but also Two, Eight, Twelve. That population expands the horror.
Documents and leaks: build mystique by fragments
Classified projects become famous through declassified or leaked documents. Mr. Robot, The X-Files and Annihilation use papers, tapes and memos as in-world evidence. For your narrative, write two to five fragments: censored report cover with redacted words, internal memo from anguished coordinator, requisition of unapproved drugs for sub-project 47.
Bureaucratic format adds realism. Header with classification ('TOP SECRET // NOFORN'), page number, date, limited distribution. Body text in dry technical language. Signatures may be redacted. When your protagonist finds this in an archive basement, the reader believes.
Referential dialogues: two characters who were in the program speak in code. 'Aurora ended badly'. 'That was before Helix'. 'After Cassandra I didn't participate anymore'. Without explaining what each one does, the reader assembles timeline fragments. This technique is more powerful than direct exposition.
