Class Notes:
The Navy informed MARAD on 16 April 1969 that the Navy's FY 1969 program included the conversion of a VC2-S-AP hull in the NDRF to a range instrumentation ship. The Navy had selected the CLEARFIELD (APA 142) in the James River Fleet and the SHERBURNE (APA 205) in the Suisun Bay Fleet, the final selection between the two to be based on the preference of the successful contractor. [On list 16 Apr 1969.] Approved characteristics for an operational test instrumentation ship, T-AGM(FBM), SCB Project No. 731.69, were promulgated on 25 April 1969 with a final change on 16 April 1970. On 21 October 1969 the Navy informed MARAD that as a result of the contract award to Northwest Marine Iron Works of Portland, Ore. (which probably occurred in mid-October), SHERBURNE had been selected and requested transfer of the ship. On 26 April 1971 SECNAV changed the classification and name of the ship from MCV 553 SHERBURNE (ex-APA 205) to T-AGM 22 RANGE SENTINEL.
