Force structure, readiness, power projection, and deterrence: the Bureau’s strategic assessment of Costa Rica’s military capability — scored 0–100 across 24 causal dimensions.
The 45.68/100 rests first on Force mass (69.00), Land warfare (69.00), Command & control (65.00). 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).

Costa Rica abolished its army on 1 December 1948. There is no standing military: air assets belong to the police Servicio de Vigilancia Aérea (15 aircraft reported 2016, only ~half operational at any time), the coast guard is a police service, and land security is the Fuerza Pública. No armour, artillery, or missile systems. A short section is correct — this is the entire inventory.

Status: Non-nuclear-weapon state
No army, no missiles, no nuclear programme; Tlatelolco signatory.
Ministry of Public Security (Ministerio de Seguridad Pública de Costa Rica): National Police (Fuerza Pública), Air Surveillance Service (Servicio de Vigilancia Aérea), National Coast Guard Service (Servicio Nacional de Guardacostas), Drug Control Police (Policía Control de Drogas), Border Police (Policia de Fronteras), Professional Migration Police (Policía Profesional de Migración) Ministry of Presidency: Directorate of Intelligence and Security (DIS), Special Intervention Unit (UEI) (2025)
approximately 10-15,000 Ministry of Public Security personnel (2025)
the National Police are lightly armed although small special units are trained and equipped for tactical operations; the US has provided equipment and support to forces such as the Coast Guard, including secondhand US vessels and aircraft (2025)
Costa Rica relies on specialized paramilitary units within the Ministry of Public Security (MPS) for internal security missions and countering transnational threats such as narcotics smuggling and organized crime, as well as for participating in regional security operations and exercises; MPS forces have received advisory and training support from the US (2025)
MILITARY POWER 45.68/100 — 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 +3 — Quarterly momentum: the Bureau's read on the country's trajectory over the last quarter, from −10 (deteriorating fast) to +10 (accelerating).
Continuity held in San José: steady services and tech exports, the crime-fighting agenda advancing without institutional rupture.
A small, stable democracy executing its plan — modestly positive, as the score says.
