2008: China appears to be having more
success with using some of its older 053H (Jianghu class) missile frigates as
coast guard patrol ships, then it ever had using them as warships. Two of these
three decade old warships, instead of being scrapped, converted to coast guard
ships. The frigates had their two 100 mm guns and six anti-ship missiles
removed. This made room for smaller patrol boats to be mounted on deck, along
with winches to lower them into the water. Additional fuel stowage was also
added, and crew accommodations were improved, since only about half as many
sailors (about a hundred) were now needed to run the ship.
Chinese apparently also did a lot of repairs and rebuilding inside these ships,
which have a long history of shoddy construction and frequent equipment
breakdowns. The coast guard has said they would prefer new ships, but this is
China, and you take what you can get and make the most of it.
