Common Missile
US intercontinental ballistic missile project

Common Missile was an intercontinental ballistic missile project, developed to satisfy U.S. Navy and U.S. Air Force operational system requirements for both SLBM and silo-launched ICBM, defined in the 1978 commonality study.
Description
The Common Missile was designed as a four-stage solid propellant, stellar-inertial guided intercontinental ballistic missile capable of delivering up to six Mark 21 reentry vehicles to independent targets. It is propelled from a canister by a gas generator prior to first stage ignition. The post boost vehicle consists of a structure to house the guidance and solid propulsion systems and a platform to mount the reentry vehicles. The post boost vehicle provides the reentry vehicle spacing and deployment maneuvers. The basic dimensions, length, and diameter, were derived from submarine launcher volumetric constraints. The booster stages were sized to provide for Navy guidance access requirements at the II-III interstage and for at-sea maintenance access. The missile was designed to fill the current Trident submarine tube.

Why this record matters
A short description can identify a subject without explaining its stakes. For “Common Missile”, the useful work is to connect “uS intercontinental ballistic missile project” to the records capable of establishing context and consequence.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 24, 2026. The linked authority identifier is Q30250529. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1978 and 1983.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
