Review Lens

Adversarial questions for candidates

The falsifiable questions this brain puts to a dissertation candidate. They seed the pre-Conclave initial review whenever a candidate's topic matches the Classical Strategy lens.

  1. 1

    Chokepoint identification: "Name the three orbital or cislunar positions whose loss or denial would most degrade your actor's freedom of action, and show — with transfer-energy or throughput numbers — *why those three* and not others. If your architecture distributes value uniformly across orbit, you have misread the geography." (Falsifiable: the candidate either produces a ranked, quantified chokepoint list or does not.)

  2. 2

    Command vs. governance: "You propose a rules regime (STM / common-heritage / data-sharing). State the specific mechanism by which it is *enforced at the decisive narrows* against an actor who defects. If the only answer is voluntary compliance, explain why this case differs from every strategically valuable narrows in naval history that great powers refused to neutralize." (Falsifiable: an enforcement mechanism is specified and tested against a defection scenario, or it is not.)

  3. 3

    Lines of communication under attack: "Identify the single highest-throughput, lowest-redundancy arc in your logistics or data architecture, and state what happens to the whole system if it is severed for 30, 90, and 180 days. If you cannot name your most vulnerable LOC, you have not done the analysis." (Falsifiable: a named arc + a graceful-degradation or collapse trajectory.)

  4. 4

    Political-economy closure: "Show the loop: what commerce or mission value funds your capacity, and how that capacity protects the commerce that funds it. If security, sustainability, and economics are separate chapters in your dissertation, they are separate in your strategy too — and Mahan would call that a fatal partition." (Falsifiable: an explicit, quantified feedback loop, or its absence.)

  5. 5

    Capacity ceiling: "State the carrying-capacity number for the regime you are operating in and the source of that number. Then show that your proposed level of use stays inside it. A strategy that cannot name the ceiling of the commons it depends on is commanding nothing — it is gambling." (Falsifiable: a cited capacity figure and a demonstrated margin, or not.)

Core Concepts & Space Translation

Command of the sea (command of the commons)

Mahan's central claim in *The Influence of Sea Power upon History, 1660–1783* (1890) is that a dominant naval power secures not the ownership of the ocean but *control of its use*: the ability to move freely while denying that freedom to a rival. The commons is never "held" the way territory is held; it is *commanded* through the capacity to concentrate decisive force at the points that matter. Translated to space, the concept maps to control-of-use over orbital regimes and transit corridors rather than sovereignty over orbits (Bowen 2017).

Lines of communication (LOC) as the object of strategy

For Mahan, the purpose of command was to protect one's own *lines of communication* (the sea routes carrying trade, troops, and supply) and to threaten the enemy's. Strategy is organized around the security of these arteries, not around territory per se. In space this becomes the protection of orbital transfer arcs, resupply logistics, and the data/command links on which space operations depend (Ishimatsu, de Weck & Hoffman 2015; Borowitz et al. 2021).

Chokepoints and strategic position

Mahan emphasized that command is exercised at *geographically privileged narrows* (Gibraltar, Suez, Malacca, the Cape) where traffic is forced to concentrate and where a small force can produce outsized effect. "Strategic position" combines physical geography, the value of the traffic that passes, and the ease of defending or contesting it. The space analogues are libration (Lagrange) points, low-energy transfer nodes, GEO slots, and launch ranges - places where the orbital-mechanical "geography" forces concentration (Koplow 2025; Colombo, Martinez & Letizia 2025).

The six elements of sea power (national conditions for maritime strength)

In *The Influence of Sea Power upon History* Mahan enumerated geographical position, physical conformation, extent of territory, population, national character, and character of government as the determinants of whether a nation can become a sea power. The framework is a *capacity audit*: it asks not "what does a fleet do" but "what national base sustains command over time." Applied to space, it becomes an industrial-base and institutional-capacity test for spacefaring power.

Concentration of force and the fleet-in-being

Mahan inherited and sharpened the doctrine that decisive results come from *concentrating* battle power rather than dispersing it for commerce protection, and that even an inferior, preserved fleet ("fleet-in-being") shapes an adversary's behavior by its mere existence. The orbital analogue is the deterrent and shaping value of resilient, survivable space architectures and responsive-launch reserves rather than dispersed, brittle constellations (Bowen 2020).

Commerce, sea power, and national prosperity (the political-economy engine)

Mahan's deepest argument is causal and economic: maritime commerce generates wealth, wealth funds the navy, and the navy protects the commerce - a self-reinforcing loop in which strategy and economy are inseparable. The space translation is that orbital and cislunar commerce, sustainability of the orbital commons, and security capacity are a single coupled system, not separable policy domains (Koplow 2025).
