Overview and identity
HMCS Swansea is documented as one canadian-built ship in the River-class production lineage.
HMCS Swansea can be distinguished by the hull or pennant designation K328, membership in River class frigate, and service with Royal Canadian Navy. Its history belongs to World War II and postwar era and to the broader development of frigates and ocean escorts. Frigates and ocean escorts were designed for sustained protection of shipping and naval formations. Anti-submarine sensors and weapons, seakeeping, range, and reliable machinery were often more important than the heavy surface armament associated with larger combatants.
Construction and class context
The sources reviewed do not provide a complete builder and construction chronology for HMCS Swansea. Construction dates help place the ship within its class program and distinguish the original build from later changes in name, classification, armament, or mission.
The River class was the first mass-produced Allied ocean frigate design of the Second World War, combining Flower-class-style economical machinery and merchant-yard construction practice with a larger twin-screw hull suited to North Atlantic escort work. Transfers, renamings, and temporary loans are presented as successive stages in each ship’s service history. The four Australian Bay-design frigates commonly called Modified Rivers are retained as a documented Australian configuration within this production lineage. Published class totals vary because sources group cancellations, modified Australian ships, procurement identities, and cross-navy transfers differently. The class history explains the common design; this article concentrates on the evidence specific to HMCS Swansea, including construction, assignments, modifications, transfers, and fate where documented.
Service history
The sources reviewed establish HMCS Swansea's identity and class membership but do not provide a complete operation-by-operation service history. Names and designations documented during the ship’s career include HMCS Swansea (Royal Canadian Navy).
As a member of River class frigate, HMCS Swansea began with the design, machinery, protection, and mission assumptions shared by the class. Those assumptions included protection of merchant and naval convoys, anti-submarine warfare, and long-range escort duty. Ship-specific refits, damage repair, transfers, reclassification, and changing assignments could alter that baseline. Class-level information is therefore used as context, not as proof that every feature remained aboard throughout this ship's career.
Technical configuration
The British-built wartime River configuration, dated from 1942, is presented as a class-level configuration used for context. Its listed characteristics include displacement 1,370 long ton (standard), length 91.8 m, beam 11.1 m, and draft 4.0 m. The recorded armament is Two single 4-inch guns, Oerlikon light antiaircraft weapons, Hedgehog anti-submarine projector, depth-charge throwers and rails; individual ships varied by completion date and refit. For HMCS Swansea, it should be read as shared class context rather than proof of a ship-specific fit on every date.
The Canadian-built River configuration, dated from 1943, is presented as a class-level configuration used for context. Its listed characteristics include displacement 1,445 long ton (standard), length 91.9 m, beam 11.1 m, and draft 3.9 m. The recorded armament is Typically a twin 4-inch mounting forward, 12-pounder aft on many ships, Oerlikon light AA, Hedgehog, and a large depth-charge outfit. For HMCS Swansea, it should be read as shared class context rather than proof of a ship-specific fit on every date.
The Australian River Group I configuration, dated from 1943, is presented as a class-level configuration used for context. Its listed characteristics include displacement 1,489 long ton (standard), length 91.9 m, beam 11.2 m, and draft 3.66 m. The recorded armament is Two 4-inch guns with 40 mm and 20 mm light AA, Hedgehog/Squid anti-submarine weapons depending on date, and depth charges. For HMCS Swansea, it should be read as shared class context rather than proof of a ship-specific fit on every date.
Later service and disposition
Later service and final fate have not been confirmed in the sources reviewed.
The sources reviewed do not identify HMCS Swansea as preserved. Its history must therefore be reconstructed through documents, photographs, technical records, and evidence connected to the class and operating navy.
Historical significance
HMCS Swansea is significant as an individual example of how River class frigate moved from a design program into operational service. Its value lies in connecting a specific vessel, its identities, and its known service outcome to the wider history of the class.
The evidence currently available for HMCS Swansea is strongest on its documented names and designations and its final status. The article separates those ship-specific facts from the shared characteristics of River class frigate, so readers can see both what is known about this vessel and where the historical record still needs stronger documentation.
Class relationship
This ship is recorded as a member of River class frigate. Shared design history belongs on the class page; this page concentrates on the individual hull where evidence is available.
