Well thougths its better than nothing to launch down new T-43 type minesweeper, i would like to see some sort of mass production to begun whit the earlyer Mine hunter type vessel as it presents more of what china needs to make its MCM force par whit other major navyes.
In modern minesweeping technics, a rather genuine step took place in the aerly 80's when major NATO navyes begun to replace their WWII era US build minesweepers. The new products were dedicate build mine hunters whit remotely controlled submersibles to hunt down advance bottom-mines and other new generation of mine hunting sonars. Also, these boats introduced the Glass reinforced plastic (GRP) hulls to military ship building and also, many of the new generation of vessels (such as British Sandown and Hunt classes, German Hamenl and the famous Tripartie) could also controll remotely controlled drone mine sweepers to do the actual minesweeping task where the human manned ships dealed the less dangerous hunting task.
Soviet Union folowed whit these paths along their Gorya class MCM vessels, but generally their most numerous MCMs were ordianry sweepers whit some hunting capapility.
China in other hand has totally wondered in WWII era world and completely neglected this one of the most important task of martime military forces.
