USS Havre (PCE(C)-877) was a United States Navy PCE-842-class patrol craft escort in commission from 14 February 1944 to 1 July 1970.

Unlike other ships from this class, which were scrapped or sold to other nations, the vessel stayed the property of the United States Navy, which transferred ownership to the United States Navy Reserve as Naval Reserve Training Ship for 9th Naval District (Chicago) in April 1954.

She was renamed USS Havre (PCE-877) on 15 February 1956 as part of a Navy-wide initiative to provide names to all numbered ships.

The USS Havre was laid down on 6 May 1943 at Albina Engine & Machine Works, Portland, Oregon, as Patrol Craft Escort, PCE-877.

The PCEs were designed for general escort work and provided a cheaper and quicker alternative to the larger destroyers, while maintaining a substantial amount of detection and ranging gear used for locating submarines.

The vessel received its fitting out and shakedown over the next six weeks, departing Portland, Oregon on 25 February 1944, docking in Astoria, Oregon on 26 February 1944, arriving in San Pedro, California (SCTC Terminal Island) on 6 March 1944, before finally arriving at Naval Base San Diego, California on 21 March 1944.

At 1200 hours on 11 September 1944, the PCE-877 officially was underway to Naval Station Pearl Harbor as part of Task Unit 116.1.2.

The ship proceeded to the northern part of San Clemente Island, California where the crew "ran a measured mile to check the accuracy and adjust our newly installed DRT (Dead Reckoning Tracer).

"[2] At 1030 hours 19 September 1944, the PCE-877 arrived at Naval Station Pearl Harbor, Hawaii for conversion to a Central Control Vessel for Amphibious Force.

"[3] Refitting was completed on 2 December 1944, and for six days the PCE-877 acted as Officer in tactical command (OTC) for a training group of control vessels between Pearl Harbor and Waianae, Hawaii.

A second series of drills and exercises starting 18 December 1944 running nine days saw the PCE-877 acting as an Escort Commander for screening and as a Line of Departure Control Vessel in simulated landing operations.

"[6] At 0540 of 19 February 1945, the PCE-877 secured from screening operations and proceeded independently to assume duties as Central Control Vessel.

All assault waves were dispatched on schedule, and the ship maintained station for the entire day, except when on standby as rescue vessel for the U.S.S.

[9] Starting 10 March 1945, the ship took aboard stores and provisions and made repairs on sound gear (due to a transformer failure) and on the starboard screw.

"[10] Starting 15 March 1945, the PCE-877 acted as the central control vessel directing practice landings on Leyte, while completing the sonar and propeller repairs over ten days.

"Friendly ships fired and shot down three FMs Mitsubishi F1M over land in the vicinity of the airstrip east of Purple Beach.

Over these three weeks, the main engine was overhauled, further repairs to the starboard propeller we attempted and continued vibration issues reported to Service Squadron Ten.

On 13 May 1945, the PCE-877 reported ready for sea, and was assigned as an escort vessel for Task Unit 94.18.10 heading back to Okinawa, departing 15 May 1945.

At 0012 on 28 May 1945, an enemy plane passed directly overhead, causing radar-controlled anti-aircraft fire for several minutes, with hundreds of rounds bursting close aboard.

Twelve minutes later (0024) an enemy suicide plane crashed into the USS LCS 119 (Landing Craft Support) just to the south of the PCE-877's position.

At 0412 the port main engine failed due to a break in a lube oil line which in turn stripped a series of bearings on the crankshaft.

On 31 July 1945, the ship was designated as a senior escort vessel and commander of the anti-submarine warfare (ASW) screen in the transport anchorage area.

[16] Administratively, the PCE-877 was formally reclassified PCE(C)-877 on 20 August 1945 (even though the conversion to Escort-Control took place 10 months prior at Pearl Harbor).

The ship had a large amounts of "Speed Letters" indicating discharges and a imminent return stateside in late September and early October 1945.

Following the end of World War II, the PCE(C)-877 returned to the United States by way of Pearl Harbor (December 1945-January 1946), where Commanding Officer Lieutenant Christian G. ("Dutch") Schmidt, USNR was relieved by Lieutenant Junior Grade John P. Johnson, USNR,[18] with Lt. (jg) Clifford I.D.

The USS Havre (PCE-877) had spent sixteen years primarily moored at USNTC Pier Great Lakes Illinois.

On 9 May 1970, the ships moved west to an anchorage near Port Colborne, Ontario, Canada and then entered the Welland Canal the next day, entering Lake Ontario at 1812 in a column formation and on 11 May 1945 embarked various Seaway Pilots for transiting segments of the St. Lawrence Seaway, and mooring on 12 May 1945 in Montreal, Quebec, Canada.

The task unit then steamed around Cape May, New Jersey, entering the Delaware River Channel, and moored at 1240 on 21 May 1970 at Pier #1 Philadelphia Naval Shipyard.

Several of the other ships in her final task unit lived longer in the commercial world: The PCE-877 received the following awards during her career:
