Force structure, readiness, power projection, and deterrence: the Bureau’s strategic assessment of Nauru’s military capability — scored 0–100 across 24 causal dimensions.
The 26.7/100 rests first on Command & control (65.00), Alliances (48.12), Force mass (36.00). 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).
Type-by-type inventory in preparation — this dossier deepens as coverage grows. Nothing here is estimated silently.
Kernel assessment: Land warfare 36.00/100 (observed).
Type-by-type inventory in preparation — this dossier deepens as coverage grows. Nothing here is estimated silently.
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.
Type-by-type inventory in preparation — this dossier deepens as coverage grows. Nothing here is estimated silently.
Status: Non-nuclear-weapon state; party to the Treaty of Rarotonga (signed 17 Jul 1986, deposited 13 May 1987).
no regular military forces; Nauru Police Force
under the terms of a security deal signed in December 2024, Australia and Nauru agreed to “deepen and expand security cooperation” and “consult and consider” in the event of threats; Nauru pledged to seek Australia’s agreement before it signed any bilateral accords on maritime security, defense, and policing, and would receive Australian financial assistance in support of Nauru's police and security needs Nauru 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 Nauru's 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 26.7/100 — 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).
No single event defined Jul–Sep 2026. The country's position is the product of long-cycle forces — geography, trade, neighbours — all of which held steady.
Momentum at zero is not stagnation; it is the accurate record of a quarter without a catalyst.
