RADAR — DATA SOURCES AND MODEL BOUNDARIES Reviewed: 2026-10-13. Individual datasets have different reference dates. PUBLIC INVENTORY ESTIMATES Source: SIPRI Yearbook 2025, World nuclear forces. https://www.sipri.org/yearbook/2025/06 Reference date: January 2025. These are estimates, not live intelligence. Total inventories include retired weapons awaiting dismantlement where applicable. They must not be interpreted as deployed or immediately available warheads. Russia 5459; USA 5177; China 600; France 290; UK 225; India 180; Pakistan 170; Israel 90; North Korea 50. Combined: 12241. National ownership is distinct from hosting another country's weapons. Iran is an optional scenario slot with zero assigned weapons by default; this slot is not a current intelligence assessment. BLOC MEMBERSHIP AND RELATIONSHIPS NATO membership: 32 members, checked against NATO's official membership page. https://www.nato.int/en/about-us/organization/nato-member-countries Article 5 assistance does not prescribe an automatic nuclear response. https://nato.int/en/what-we-do/introduction-to-nato/collective-defence-and-article-5 China describes its relationship with Russia as non-alliance, non-confrontation and not targeting third parties. Chinese entry is OFF by default. https://www.fmprc.gov.cn/eng/wjb/wjbz/hd/202503/t20250307_11570111.html Russia-North Korea bilateral treaty context and China-North Korea treaty context: https://www.usfk.mil/Portals/105/Tri-Command-Glossy-2026.pdf All in-game participation timings and side choices are scenario rules, not predictions or legal interpretations. Opposition edges are scenario settings. DELIVERY CATEGORIES — HIGH-LEVEL BACKGROUND USA: land, submarine and aircraft triad. https://www.defense.gov/News/News-Stories/Article/Article/3786326/us-needs-sea-based-nuclear-capability-to-ensure-second-strike-capability/ UK: submarine-based deterrent. https://www.gov.uk/guidance/the-uks-nuclear-deterrent-the-facts France: oceanic and airborne components. https://www.defense.gouv.fr/dgris/politique-defense/la-dissuasion-nucleaire-francaise India: nuclear triad, including submarine component. https://www.pib.gov.in/PressReleaseIframePage.aspx?PRID=2049870 China: developing nuclear triad described by SIPRI; category availability does not establish operational readiness of every component. https://www.sipri.org/sites/default/files/YB24%2007%20WNF.pdf Remaining platform categories are simplified representations of public assessments. Israeli capabilities are opaque; do not label them officially confirmed. North Korean submarine launch operations are omitted by default. No real surface-ship nuclear deployment is asserted by this game. That option is an explicit hypothetical override and starts OFF. GAME PARAMETERS — NOT FACTS deployments.csv: all coordinates and stationing names are fictional. platforms.csv: flight times and cooldowns are abstract game seconds. effects.csv: abstract display/exposure units, not physical blast or dose models. objects.csv: fictional scenario objects, not actual strategic targets. scenarios.csv: game pacing and launch caps. There are no real bases, patrol tracks, targeting plans, yields, interception calculations, meteorological fallout predictions or operational weapon ranges. Platform selection uses available fictional stations in a stable rotation. PERSONAL REPORT Exposure combines simplified geometric effects and a shelter modifier. The survival index is NOT a percentage probability. No empirical survival model has been fitted or validated. Seven-day outcomes are not modeled.
