Jamaica — Military Capability Assessment

The 34.45/100 rests first on Force mass (66.00), Land warfare (66.00), 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.

• Alliance architecture adds a +5.78 bonus.
• Nuclear deterrence contributes a capped +0.68 bonus — it cannot manufacture top-tier conventional standing on its own.
• Extreme defense burden applies an economic-strain penalty of −2.00.
• Force mass is capped by what equipment, training and sustainment can actually support — headcount alone scores nothing.

10 of 24 dimensions could not be observed (Equipment quality, ISR & intelligence, Missile forces, Air defense, Cyber & space, Strategic lift…); missing data caps the score — it never inflates it.

Assessment coverage: 60.9% — 14 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).

Missile forces could not be observed in this assessment — missing data caps the score, it is never treated as zero.

Status: non-nuclear-weapon state

Jamaica Defense Force (JDF): Jamaica Regiment (Land Force), Maritime, Air, and Cyber Command (MACC), Support Brigade, Caribbean Military Academy, Jamaica National Reserve (2025)

approximately 4,000 active Jamaica Defense Forces (2025)

the JDF's inventory features equipment mostly from Australia, the Netherlands, and the US (2025)

18-23 for voluntary military service (17 with parental consent) for men and women; 18-28 for the reserves; no conscription; since 2017, the JDF's standard mode of recruitment is to enroll recruits ages 18-23 through the Jamaica National Service Corps (JNSC), which has a service requirement of 12 months (2025)

in addition to its responsibility of defending against external aggression, the Jamaican Defense Force's (JDF) primary missions are border, cyber, internal, and maritime security; other missions include search and rescue, disaster response, humanitarian assistance, and peacekeeping; it has arrest authority and partners with the Jamaica Constabulary Force (JCF), particularly in support of combating crime and violence; both the JDF and JCF are under the Ministry of National Security, which directs policy for the security forces; the JDF participates in bilateral and multinational training exercises, including with the armed forces of Canada, the UK, the US, and other Caribbean nations while Jamaica had a militia force as early as the 1660s, the JDF was constituted in 1962 from the West India Regiment (WIR), a British colonial regiment which dates back to 1795 (2025)
