Force structure, readiness, power projection, and deterrence: the Bureau’s strategic assessment of Marshall Islands’s military capability — scored 0–100 across 24 causal dimensions.
The 31.86/100 rests first on Command & control (65.00), Alliances (48.12), Force mass (47.00). The binding constraints: Air power (8.00), Submarine force (8.00), Nuclear survivability (6.50) — in a causal model, capability can never rise above its weakest observed link. What would move the needle: Air power (8.00) — the weak link in the spending → equipment → readiness → capability chain.
13 of 24 dimensions could not be observed (Mobilization, Equipment quality, Readiness & training, ISR & intelligence, Missile forces, Air defense…); missing data caps the score — it never inflates it.
Assessment coverage: 47.8% — 11 of 24 dimensions observed. Kernel v10, run 2026-10-04; evidence snapshot: CIA World Factbook 2026-09-28, SIPRI arms-producer revenue, v9 nuclear taxonomy.
Kernel assessment: Air power 8.00/100 (observed).

Kernel assessment: Land warfare 47.00/100 (observed).

Kernel assessment: Naval power 22.80/100 (observed).
Type-by-type inventory in preparation — this dossier deepens as coverage grows. Nothing here is estimated silently.
Missile forces could not be observed in this assessment — missing data caps the score, it is never treated as zero.

defense is the responsibility of the US; in 1982, the Marshall Islands signed a Compact of Free Association (COFA) with the US, which granted the Marshall Islands financial assistance and access to many US domestic programs in exchange for exclusive US military access and defense responsibilities; the COFA entered into force in 1986; the Marshall Islands hosts a US Army missile test site the Marshall Islands has a "shiprider" agreement with the US, which allows local maritime law enforcement officers to embark on US Coast Guard (USCG) and US Navy (USN) vessels, including to board and search vessels suspected of violating laws or regulations within its designated exclusive economic zone (EEZ) or on the high seas; "shiprider" agreements also enable USCG personnel and USN vessels with embarked USCG law enforcement personnel to work with host nations to protect critical regional resources (2025)
MILITARY POWER 31.86/100 — The Magna Military Power score is our 0–100 measure of causal military capability — 24 dimensions (mass, equipment, readiness, projection, industry, nuclear deterrence), aggregated through a dependency graph, never by simple addition.
Momentum 0 — Quarterly momentum: the Bureau's read on the country's trajectory over the last quarter, from −10 (deteriorating fast) to +10 (accelerating).
The quarter passed without decisive turns. Governance continued, markets functioned, and the score reflects that uneventfulness.
For countries like this, the real story is always the slow one — and this quarter added no new chapter to it.
