Emory S. Land-class submarine tender equipment records. Variants, orders and quantities are shown as reported in each inventory source; coverage is incomplete.
United StatesService Support (PM4) exact named class holdings of Emory S. Land. 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): LOGISTICS AND SUPPORT / AS. No heading aggregate, carried armament, crew, payload, factory production or future order count inherited. The source declares a separate Service Support (PM4) subsection within Military Sealift Command (MSC). The own fetched design source declares this exact class and its PDF operator country; ship capacities and fitted launcher/armament counts are retained as source scope, not added to hull quantities.
Reported count for Emory S. Land-class. Service scope: Navy; does not replace a national total. 1 distinct count cell(s) from the same source list; shared rowspan cells counted once. Excludes retired/reserve/on-order rows. Count column(s): active: 2. Origin: unstated. The listed variants/roles are the scope, not an immediately deployable count. The components do not establish one inventory census date; the stored date is the retrieved source snapshot.
