𝟐𝟎𝟐𝟑 Apr: Interim Defence Strategic Review

𝐎𝐯𝐞𝐫𝐯𝐢𝐞𝐰
In April 2023 the Government released the unclassified Defence Strategic Review and its response, following interim, classified advice provided earlier that year to accelerate posture, preparedness, and investment choices. The interim advice shaped urgent priorities—strike, IAMD, undersea denial, and northern dispersal—so Cabinet could redirect funding and scheduling while classification processes concluded, establishing a bridge toward recurring strategy cycles and a re-sequenced investment program.

𝟏. Interim Review: Classified early advice guiding urgent posture, preparedness, investment decisions.
𝟐. Independent Leads: Stephen Smith and Angus Houston directing scope, method, findings.
𝟑. Warning Time: Compressed risk window driving readiness, sustainment, and stock targets.
𝟒. Force Posture: Basing, dispersal, logistics aligned to northern approaches and ranges.
𝟓. IAMD: Layered sensors, shooters, C2 protecting forces from missile threats.
𝟔. Undersea Denial: Submarines, sensors, strike constraining adversary freedom of action.
𝟕. GWEO: Guided weapons enterprise delivering stocks, manufacture, maintenance resilience.
