This is a list of patrol vessels of the United States Navy.

Ship status is indicated as either currently active [A] (including ready reserve), inactive [I], or precommissioning [P]. Ships in the inactive category include only ships in the inactive reserve, ships which have been disposed from US service have no listed status. Ships in the precommissioning category include ships under construction or on order.

Assault Support Patrol Boat (ASPB)

Eighty-six Assault Support Patrol Boats were built for use in the Vietnam War.

Patrol air cushion vehicle (PACV)

The Navy used 3 Patrol Air Cushion Vehicle hovercraft in Vietnam.

Hydrofoil vessels

Patrol boat, river (PBR)

The Patrol Boat, River was acquired for the Vietnam War: 718 of these 31/32-foot long boats were purchased with a peak of 250 used in Vietnam.

Patrol craft coastal (PC)

The original PC hull number sequence ended in 1964, and was then restarted with '1' for this class.

Cyclone-class

Patrol craft (PC)

The following submarine chasers were 173/174 feet long and used the PC designation. The large missing sections of these numbers for the most part come from the sharing of the same number sequence with the 110-foot submarine chasers that used the SC designation and the 134-foot patrol craft sweepers that used the PCS designation. This number sequence would end in 1964, and then restart with '1' for the Cyclone-class costal patrol craft.

• USS PC-451 (experimental ship)
• USS PC-452 (experimental ship), later IX-211

PC-461 class

497-507, 511 to 522, and 524-539 were used by SC submarine chasers

1376 to 1465 used by PCS patrol minesweepers, a few did hold the PC designation at times

The Adroit class was a group of PC-461 class submarine chasers completed as minesweepers (AM-82 through AM-99). However, they were considered unsatisfactory in this role, and were all eventually converted back into submarine chasers.^[3]

Patrol craft escort, and patrol craft escort rescue (PCE, PCER)

The Patrol Craft Escort Rescue (PCER), which were intended to rescue crews from ships attacked in convoys, were originally intended to be designated as Convoy Rescue Craft (APR), but this was designation was abandoned.^[6]

Patrol craft fast (PCF)

The Patrol Craft Fast, also known as the Swift Boats, were acquired for the Vietnam War; 193 of these 50 foot boats were purchased.^[7]

Patrol craft sweeper (PCS)

At least 90 134-foot YMS-1-class minesweeper hulls were completed as patrol craft. These were judged to not be successful, and many were converted to sonar school ships or back to minesweepers.^[8]

Patrol escort (PE)

Of 112 Eagle class patrol craft planned 60 of these World War I era ships were completed, being given numbers from 1 to 60. Only three were commissioned prior to the Armistice which ended World War I and only eight saw service in World War II of which PE-56 was sunk by a U-boat.

PE-61 through PE-112 were cancelled on November 30, 1918. PE-5, PE-15, PE-25, PE-45, PE-65, PE-75, PE-86, PE-95, PE-105, and PE-112 were allotted for transfer to Italy, though this plan was cancelled and none were ever delivered.

Patrol frigate (PF)

Destroyer escorts were designed and built to naval construction standards, and as such could only be built at yards experienced with naval standards. The United States Maritime Commission created its S2 design - which was based on the British-designed River class - for much the same role but using civilian construction standards. These ships would be classed by the Navy as the Tacoma class frigates.^[9]

Patrol torpedo boat (PT)

Patrol yacht (PY)

Patrol yacht, coastal (PYc)

Submarine chaser (SC)

These submarine chasers were 110 feet long and used the SC designation. The large missing sections of numbers in designation for the most part come from sharing the same number set as the other bigger 173 foot subchasers that used the PC designation.
