Kodiak Island
United States
Kodiak Island is strongest on Population Capacity 9/10 — Existing island communities and infrastructure already support many thousands of residents, providing exceptional shelter, sanitation, storage, transport and workspace capacity relative to twenty people.. Its clearest scored constraint is Defensibility 1/10 — Kodiak Island spans thousands of square miles with a very long coastline, multiple communities and broad wilderness. Twenty people cannot defend the canonical island as one boundary, and no specific military or municipal compound is substituted for it..

Bottom Line
For the fixed 20-person Base boundary, the most important endurance constraint is Maintenance Resilience 6/10 — Kodiak's isolated grid is unusually strong for an island because hydro supplies most generation and wind/battery systems add diversity, reducing continuous fuel dependence; protected gravity/surface-water resources and ordinary housing also retain utility. Grid machinery, distribution, pumps, transport and specialist parts still require maintenance, so resilience stops below the strongest passive classes..
Biggest Trade-off
The central trade-off is the catalogue's strongest evidenced dimension, Population Capacity at 9/10, against its weakest evidenced dimension, Defensibility at 1/10.
Most Likely Failure
The clearest evidenced failure pressure is Maintenance Resilience: Kodiak's isolated grid is unusually strong for an island because hydro supplies most generation and wind/battery systems add diversity, reducing continuous fuel dependence; protected gravity/surface-water resources and ordinary housing also retain utility. Grid machinery, distribution, pumps, transport and specialist parts still require maintenance, so resilience stops below the strongest passive classes.
Score rationale
Why it scores this way
Defensibility · 1/10
Kodiak Island spans thousands of square miles with a very long coastline, multiple communities and broad wilderness. Twenty people cannot defend the canonical island as one boundary, and no specific military or municipal compound is substituted for it.
Advantages
- Positive credit is limited to what supports the Defensibility score of 1/10; the component rationale is: Kodiak Island spans thousands of square miles with a very long coastline, multiple communities and broad wilderness. Twenty people cannot defend the canonical island as one boundary, and no specific military or municipal compound is substituted for it.
Limitations
- Do not infer additional Defensibility capability outside the fixed Base boundary or beyond the recorded evidence.
Isolation · 6/10
Gulf-of-Alaska water separation and sparse population across a very large island materially slow mass movement from mainland population centres. Kodiak still contains a local population measured in the low tens of thousands with established ports, airport and road-system communities, keeping it below the low-population 7-9 classes.
Advantages
- Positive credit is limited to what supports the Isolation score of 6/10; the component rationale is: Gulf-of-Alaska water separation and sparse population across a very large island materially slow mass movement from mainland population centres. Kodiak still contains a local population measured in the low tens of thousands with established ports, airport and road-system communities, keeping it below the low-population 7-9 classes.
Limitations
- Do not infer additional Isolation capability outside the fixed Base boundary or beyond the recorded evidence.
Sustainability · 8/10
Established communities, housing, protected potable-water systems, a resilient isolated electric grid, ports, emergency services and a major fisheries economy provide a very strong existing habitat for twenty people. Harsh weather, distributed geography and imported categories prevent an exceptional 9-class rating.

Survival horizons
How survival changes over time
First 7 days: current defence/contact profile
First 7 Days
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Exposure Control 4/10 — Sea separation removes ordinary mainland foot approaches, but the whole island has a huge coastline, multiple communities, ports, roads and substantial local population concentrated around Kodiak. Twenty survivors gain regional warning time without a manageable island-wide approach set..
Risks
- The weaker current condition in this horizon is Defensibility 1/10 — Kodiak Island spans thousands of square miles with a very long coastline, multiple communities and broad wilderness. Twenty people cannot defend the canonical island as one boundary, and no specific military or municipal compound is substituted for it.; no better future state is assumed.
First 100 days: current habitat/capacity profile
First 100 Days
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Population Capacity 9/10 — Existing island communities and infrastructure already support many thousands of residents, providing exceptional shelter, sanitation, storage, transport and workspace capacity relative to twenty people..
Risks
- The weaker current condition in this horizon is Sustainability 8/10 — Established communities, housing, protected potable-water systems, a resilient isolated electric grid, ports, emergency services and a major fisheries economy provide a very strong existing habitat for twenty people. Harsh weather, distributed geography and imported categories prevent an exceptional 9-class rating.; no better future state is assumed.
Long term: current resource/maintenance profile
Long Term
This horizon does not invent future upgrades or resupply. It carries the current evaluated conditions forward and keeps unknown future capability uncredited.
Positive factors
- The stronger current condition in this horizon is Resource Security 8/10 — Protected high-quality surface-water sources, predominantly local hydro/wind electricity, diesel backup and exceptionally productive fisheries create unusually strong independent water, energy and protein pathways. Food diversity, fuel, specialist parts and many manufactured supplies still rely on outside logistics, keeping Kodiak below the exceptional 9-class resource position..
Risks
- The weaker current condition in this horizon is Maintenance Resilience 6/10 — Kodiak's isolated grid is unusually strong for an island because hydro supplies most generation and wind/battery systems add diversity, reducing continuous fuel dependence; protected gravity/surface-water resources and ordinary housing also retain utility. Grid machinery, distribution, pumps, transport and specialist parts still require maintenance, so resilience stops below the strongest passive classes.; no better future state is assumed.
Tactical assessment
Practical Reality
Reality Check
Scores apply only to the defined Base and exactly 20 capable adults. Unknown, excluded or external assets are not credited as hidden capability.
Best Use
Within the evaluated boundary, treat Population Capacity as the primary operational strength; do not promote that score into capabilities the evidence does not establish.
Key Risk
Maintenance Resilience is the key evidenced long-duration risk: Kodiak's isolated grid is unusually strong for an island because hydro supplies most generation and wind/battery systems add diversity, reducing continuous fuel dependence; protected gravity/surface-water resources and ordinary housing also retain utility. Grid machinery, distribution, pumps, transport and specialist parts still require maintenance, so resilience stops below the strongest passive classes.
