01 / DOCUMENTED CORE
Start with what the record can carry.
The United States developed Project Iceworm, a Cold War concept for a network of nuclear-missile sites beneath the Greenland ice sheet; Camp Century served as a real under-ice base and research installation.
Project Iceworm was real planning, but the full missile network was not completed. Ice movement and engineering realities undermined the concept.
02 / CASE RECORD
What is established.
Project Iceworm explored a much larger hidden missile network.
The planned missile network was not completed.
Engineering studies showed that ice movement would deform underground structures.
03 / VISUAL RECORD
Images with a declared evidentiary role.
Actual Camp Century trench construction, 1960.
Technical documentation from Camp Century history.
04 / CLAIM LEDGER
One claim at a time.
CLAIM 01Project Iceworm existed as a U.S. Cold War missile concept.
DOCUMENTEDThe status applies only to this claim. It does not automatically transfer to other allegations in the file.
CLAIM 02A complete operational missile network was built beneath Greenland.
FALSE / NOT COMPLETEDThe status applies only to this claim. It does not automatically transfer to other allegations in the file.
05 / TIMELINE
The sequence matters.
- 1959–1960Camp Century is constructed.
- Early 1960sEngineering and feasibility work tests the under-ice concept.
- Mid-1960sIce movement and practical limitations undermine the plan.
- Later decadesProject Iceworm becomes publicly documented.
06 / OPEN QUESTIONS
Where the evidence stops.
How much Danish political knowledge existed at each stage of the project.
Which technical and environmental consequences remain relevant today.
