English: Chinese Frigate No.48 and No.49 are ex Soviet Navy guard ship СКР-48 and СКР-49, which initially were unfinished Type D escort ship built for IJN. They were both transferred to Chinese Navy in 1955.
This picture is taken as a screenshot from the old movie "赤峰号" (literally "Frigate Red Peak“) which was produced and published in 1959 in which No.48 and No.49 probably both starred as some ROCN frigates. However I am unable to tell whether this screenshot shows No.48 or No.49 because they are too similar.
