Construction

Investigator (YAGR-9) was laid down on 28 November 1944, under a Maritime Commission (MARCOM) contract, MC hull 2336, as the Liberty Ship Charles A. Draper, by J.A. Jones Construction, Panama City, Florida. She was launched 9 January 1945; sponsored by Mrs. E. L. Cills; and delivered 24 January 1945, to the Polarus Steamship Co., Inc. [5] [2]

Service history

The ship carried replacement aircraft and cargo until the end of the war. She entered the National Defense Reserve Fleet, James River Reserve Fleet, Lee Hall, Virginia, 26 October 1945. [5]

After a brief period of service in 1947, she entered the Reserve Fleet at Mobile, Alabama, until she was acquired by the US Navy, 2 July 1956. She was converted to a radar picket ship at the Charleston Navy Yard, Charleston, South Carolina, and commissioned Investigator (YAGR-9), 16 January 1957. [5] [3]

Equipped with the latest in air search and tracking systems, the ship conducted her shakedown training in the Caribbean, and departed Guantanamo Bay, for her new home port, Davisville, Rhode Island. Investigator began her operational pattern of three- to four-week cruises in the North Atlantic Ocean as the seaward extension of the Continental Air Defense Command's (CONAD) air early warning system. Operating with search aircraft, she could detect, track, and report aircraft at long ranges, and could control high speed US interceptor aircraft and direct them to targets. [5]

The ship was reclassified AGR-9, effective 28 September 1958. She continued radar picket station duties for CONAD, detecting and tracking inbound airborne objects and controlling jet interceptor aircraft until decommissioned 29 March 1965. [5]

Decommissioning

Her name was struck from the Navy List 1 April 1965. She was transferred the same day to the US Maritime Commission (MARCOM) and entered the Hudson River Reserve Fleet, Jones Point, New York, where she remained until sold for scrapping in Spain, 15 May 1971. [5] [3]

<span class="mw-page-title-main">Radar picket</span> Station used to increase radar detection range

A radar picket is a radar-equipped station, ship, submarine, aircraft, or vehicle used to increase the radar detection range around a nation or military force to protect it from surprise attack, typically air attack, or from criminal activities such as smuggling. By definition a radar picket must be some distance removed from the anticipated targets to be capable of providing early warning. Often several detached radar units would be placed in a ring to encircle a target to provide increased cover in all directions; another approach is to position units to form a barrier line.

<span class="mw-page-title-main">Atlantic Reserve Fleet, Wilmington</span> US Atlantic Reserve Fleet, in Wilmington, North Carolina

Atlantic Reserve Fleet, Wilmington was part of the United States Navy reserve fleets in Wilmington, North Carolina at 34.229479°N 77.982916°W. The reserve fleet was at and overflowed out of the former North Carolina Shipbuilding Company in the dredge out Brunswick River. The ships lined both sides of the Brunswick River. The freshwater of the river made a good spot to store ships. The reserve fleet was opened in 1946 to store the now many surplus ships after World War II. The mothball fleet was mostly cargo ships used in the merchant marine navy. When opened it had mostly cargo ships and a few troop ships. At its peak it had 300 Victory ships and Liberty ships, many that were built at the nearby former North Carolina Shipbuilding Company Shipyard. Some ships in the fleet were reactivated for the Korean War and Vietnam War. Atlantic Reserve Fleet, Wilmington closed in 1962, with the last ship removed in February 27, 1970. The ships in the fleet were either scrapped, used as targets or move to the James River Reserve Fleet and Beaumont Reserve Fleet.
