Class Notes:
PVT JOE E MANN (AK 253) was among 18 Maritime Admiminstration ships to be transferred to the Navy for which names, classification, and hull numbers were approved on 31 Jul 1950 and was initially used by MSTS as a cargo ship. She was converted to a missile tracking ship by Triple A Machine Shop, Inc., of San Francisco and in about October 1958 was the first of the future AGM's to be on range. Beginning on 19 October 1958 PVT JOE E MANN came under the operational control of the Pacific Missile Range, Port Hueneme, Calif. She was used as a telemetry ship in the DISCOVERER series. The instrumentation on board was operated by Lockheed Aircraft under contract to AFBMD. The ship was under the administrative control of MSTS with a civil service crew and was under the operational control of the Navy at the Pacific Missile Range. On 24 August 1960 it was announced that she would receive a half-million dollar upgrade to her missile tracking equipment at Pacific Ship Repair in an overhaul that also included voyage repairs, the installation of air conditioning, and various other alterations.

On 29 March 1960 a new version of SECNAV Instruction 5030.1B then in draft established a new classification, AGM, with the meaning "Missile Range Instrumentation Ship," and Commander MSTS asked that HAITI VICTORY, PVT JOE E MANN, and DALTON VICTORY, all missile range ships, be reclassed and assigned appropriate new names. The instruction was promulgated on 25 August 1960, and on 12 September 1960 Commander MSTS alerted his staff that a change of the classification of T-AK 253 (PVT JOE E MANN) to T-AGM 4 was pending in OPNAV. New names were also to be assigned. On 27 October 1960 effective 27 Nov 1960 SECNAV approved the new classifications AGM 4 and the name RICHFIELD for PVT JOE E MANN.

Around 3 October 1968 the Air Force Systems Command advised MSTS that the ship was surplus to their requirements, and MSTS transferred her to MA custody on 21 Nov 1968.
