Overview
Aggressive class is the 53-hull U.S. subgroup of the broader Agile-design family used in this archive.
Developed for United States Navy, Aggressive class belongs to the Mine warfare vessels family and is associated with Cold War. Its documented designations include Ocean minesweeper, while its intended roles include Ocean minesweeping and Mine hunting.
Development and construction
Aggressive was the first ship of the family commissioned, which is why many references use “Aggressive class” for a broader set of the design. The archive separates the documented 53 U.S. Aggressive hulls from Agile itself, the four Dash hulls, and direct-allied MDAP groups while retaining the shared parent design.
The documented program for Aggressive class lists 53 planned, 53 ordered, 53 laid down, 53 completed, and 0 cancelled, with design work beginning in 1950, construction beginning in 1951, and construction ending in 1958. These figures define the scale and chronology currently supported by the class sources.
Design characteristics and intended role
The surviving classification data associates Aggressive class with Wood hull, Non-magnetic construction, and Diesel propulsion. Read together with the recorded roles of Ocean minesweeping and Mine hunting, these attributes show the operational problem the design was intended to address without implying specifications that the sources do not establish.
The class record identifies United States Navy as the principal design or service authority. Where individual ships changed navy, name, or pennant, those later identities are retained on the ship pages rather than treated as separate vessels.
Service history and class roster
Aggressive-class ships served from the early 1950s into the 1990s. Several late survivors transferred to Taiwan, Spain, and the Philippines.
The class roster currently links 8 ships. The available record does not yet supply a complete public list of names.
Historical significance
The class formed the largest U.S. subgroup of the post-Korean-War ocean minesweeper program.
Aggressive class is most useful when read as both a design and a group of individual careers. The class page establishes the shared technical and operational context; the linked ship pages preserve differences in construction, service identity, deployment, transfer, preservation, and fate where those details are documented.
