JMSA Ukishima class minesweepers in naval review Oct-1948
A group of Japan Maritime Safety Agency Ukishima-class minesweeping vessels leaving Kobe Port to take part in the agency’s first boat parade in October 1948. The three vessels from the front are the former Type 1 Patrol boats No. 84, No. 134, and No. 136. Note the agency’s blue and white compass flag flying from each, rather than a Hinomaru or Rising Sun Flag.
