The is a cornerstone technical standard used primarily by the UK Royal Navy and the Indian Navy to define the requirements for shock testing of shipboard equipment. It ensures that critical systems—ranging from propulsion units and generators to sensitive electronics like sonar and radar—remain operational or safe during hostile engagements, specifically following underwater explosions. Core Purpose and Application Under the BR 3021 standard, shock severity is

The standard classifies equipment based on its location and criticality through specific "Shock Grades": It is primarily used to ensure that equipment

The is a British naval technical regulation that specifies requirements and testing procedures for high-impact shock resistance of shipboard equipment and systems. It is primarily used to ensure that equipment on naval vessels—especially combatant ships—remains operationally available after exposure to non-contact underwater explosions (UNDEX).

BR 3021 remains a "gold standard" for naval survivability in the UK and internationally. While it originated in the 1970s, it is still cited in modern naval procurement contracts (such as for the Indian Navy or UK MOD) to guarantee that critical combatant systems remain operationally available after a shock event.
