Qeshm Island
Iran
Qeshm Island is strongest on Population Capacity 9/10 — A current island population around 180,000 with multiple towns/villages and substantial utility/economic infrastructure provides enormous headroom above the fixed 20-person group, although water-service inequality keeps it below the most unconstrained capacity class.. Its clearest scored constraint is Defensibility 1/10 — Qeshm is a very large populated island with extensive coastline, many settlements, ports and roads. Twenty survivors cannot continuously defend the whole canonical island, and no cave, fort, port or industrial compound is substituted as the Core Base..

Bottom Line
For the fixed 20-person Base boundary, the most important endurance constraint is Maintenance Resilience 4/10 — Multiple power/desalination projects and large existing settlement infrastructure provide redundancy, while fisheries and ordinary buildings retain passive value. Essential potable-water production/distribution and major electricity generation remain machinery-, treatment-, control- and fuel/gas-dependent, so specialist failure or supply interruption can cascade across critical services..
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 evaluation leaves this material failure condition unresolved: Qeshm's unusually strong water position is materially desalination/distribution based and several large water assets are directly integrated with power-generation projects. Numeric scores are justified by real redundancy, but prolonged power/fuel/plant failure can cascade into potable-water loss and therefore remains explicit for package adjudication.
Score rationale
Why it scores this way
Defensibility · 1/10
Qeshm is a very large populated island with extensive coastline, many settlements, ports and roads. Twenty survivors cannot continuously defend the whole canonical island, and no cave, fort, port or industrial compound is substituted as the Core Base.
Advantages
- Positive credit is limited to what supports the Defensibility score of 1/10; the component rationale is: Qeshm is a very large populated island with extensive coastline, many settlements, ports and roads. Twenty survivors cannot continuously defend the whole canonical island, and no cave, fort, port or industrial compound is substituted as the Core Base.
Limitations
- Do not infer additional Defensibility capability outside the fixed Base boundary or beyond the recorded evidence.
Isolation · 2/10
Water separation creates some regional barrier, but Qeshm already contains about 180,000 residents and lies beside heavily connected mainland/Strait of Hormuz routes. Large walker pressure can therefore originate inside the island and nearby regional population remains close, fitting the large-nearby-pressure class.

Large walker pressure can therefore originate inside the island and nearby regional population remains close, fitting the large-nearby-pressure class.
Limitations
- Do not infer additional Isolation capability outside the fixed Base boundary or beyond the recorded evidence.
Sustainability · 7/10
An established island society of about 180,000 people has extensive housing, ports, utilities, desalinated-water systems, electricity and food/fisheries activity, easily supporting twenty in ordinary conditions. Hot arid climate, uneven water-service reach and heavy dependence on engineered water/power systems prevent the stronger mature-habitat classes.

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 3/10 — Sea separation constrains outside arrivals to marine/air routes, but the very long coastline, numerous ports/landing areas, road network and large resident population create a broad internal monitoring burden. The whole island offers modest approach shaping rather than a few controllable routes..
Risks
- The weaker current condition in this horizon is Defensibility 1/10 — Qeshm is a very large populated island with extensive coastline, many settlements, ports and roads. Twenty survivors cannot continuously defend the whole canonical island, and no cave, fort, port or industrial compound is substituted as the Core Base.; 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

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 6/10 — Qeshm has substantial desalinated-water production/storage, multiple current power-generation assets, major fisheries and expanding aquaculture/agricultural activity. Those resources cover several critical needs locally, but potable-water delivery remains uneven and power/water systems are engineered and fuel-dependent; full food diversity and specialist supplies remain external. This is a strong mixed resource base rather than autonomy..
Risks
- The weaker current condition in this horizon is Maintenance Resilience 4/10 — Multiple power/desalination projects and large existing settlement infrastructure provide redundancy, while fisheries and ordinary buildings retain passive value. Essential potable-water production/distribution and major electricity generation remain machinery-, treatment-, control- and fuel/gas-dependent, so specialist failure or supply interruption can cascade across critical services.; 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: Multiple power/desalination projects and large existing settlement infrastructure provide redundancy, while fisheries and ordinary buildings retain passive value. Essential potable-water production/distribution and major electricity generation remain machinery-, treatment-, control- and fuel/gas-dependent, so specialist failure or supply interruption can cascade across critical services.
