USS Weehawken

Overview and identity

Passaic-class monitor built by Zeno Secor & Co. and launched in November 1862.

USS Weehawken is identified through service with United States Navy and membership in Passaic class. Its history belongs to the ironclad transition and to the wider development of the transition from wooden warships to armored steam fleets. These identity checks separate the vessel from other ships that may have carried the same or a similar name.

Construction and class context

USS Weehawken was built by Zeno Secor & Co., Jersey City, New Jersey. The documented chronology records launched 1862-11-05. These dates place the vessel within the construction sequence of Passaic class and provide fixed points for distinguishing original features from later alterations.

The Passaic class enlarged and refined the single-turret monitor concept after USS Monitor. Ten ships were built for Union coastal operations during the Civil War, combining very low freeboard with a rotating armored turret and heavy smoothbore or rifled weapons. Operational experience quickly exposed both the strengths and limitations of the monitor form. Passaic-class vessels concentrated heavy firepower behind armor in a small target profile, but their low freeboard and restricted habitability made them better suited to coastwise and harbor fighting than open-ocean operations. This class-level history explains the common requirement and design; the present article remains focused on evidence that can be attached specifically to USS Weehawken.

Service history

Weehawken fought around Charleston and captured the Confederate ironclad Atlanta after a short engagement in June 1863; she later foundered in December 1863.

The operating context of Passaic class included coastal combatant, blockade, and shore bombardment. That context explains why the ship was built, but it is not treated as proof that USS Weehawken participated in an undocumented deployment or action. Ship-specific operations require dated orders, logs, official histories, or equivalent evidence.

Configuration and change

As a member of Passaic class, USS Weehawken shared a design baseline associated with monitor and features such as ironclad, turret-mounted weapons, low freeboard, and steam propulsion. The baseline is useful for understanding the vessel’s intended capabilities, but it does not establish that every weapon, sensor, boat, aircraft, or machinery arrangement remained aboard throughout the ship’s career.

Any dated configuration for USS Weehawken must distinguish original construction from later refits, wartime additions, repair work, transfers, and changes in mission. Where the reviewed evidence provides only class-level data, this profile presents it as context and avoids converting it into a permanent ship-specific specification.

Later service and disposition

The final status recorded for USS Weehawken is sunk on 1863-12-06.

Foundered at anchor during heavy weather.

Historical significance and evidence

USS Weehawken provides an individual case within the history of Passaic class. Its value lies in connecting one documented hull, construction chronology, service identity, and outcome to the broader design and operational history of the class.

The class made the monitor a repeatable fleet type rather than a one-off experiment and became a major branch of American ironclad development. For USS Weehawken, historical significance should remain ship-specific: the article must show what this vessel did, how it changed, and how its career differed from other members of Passaic class, rather than repeating the class article as if every ship shared one service history.

The evidence used for USS Weehawken includes Naval History and Heritage Command, “Weehawken I (Monitor).”, Naval History and Heritage Command, “NH 59269 Panoramic View of Charleston Harbor — Advance of Ironclads to the Attack, April 7th, 1863.”, and Naval History and Heritage Command, “Passaic I (Ironclad Monitor).”. These sources support the chronology and identification presented here; where they do not establish a ship-specific event or configuration, the profile says so rather than borrowing details from another vessel.

Class relationship

This ship is recorded as a member of Passaic class. Shared design history belongs on the class page; this page concentrates on the individual hull where evidence is available.
