Kalvari-class submarine (2015) equipment records. Variants, orders and quantities are shown as reported in each inventory source; coverage is incomplete.
IndiaNavy exact named equipment holdings of Kalvari (FRA Scorpene). Active, operational-reserve and training units excluding equipment in store; November 2025 IISS assessment. Named service only, not a national or parent-force total or combat-readiness measure. Source role(s): SUBMARINES / SSK. No heading aggregate, carried armament, crew, payload, factory production or future order count inherited. The leading printed inventory count is retained; separately stated extra reserve, nonoperational or repair quantities inside parentheses are not added to it and remain verbatim in the excerpt. Source parentheses retain employment, lease, reporting designation, alternate model, or included-subset scopes exactly. Own fetched primary and alternate/model identity declarations are retained. Numbers inside an included subset are part of the printed count and are never added again; no sibling or parent specification is copied.
