Type 209s are often supplemented with other submarine designs or are scheduled to be replaced by them. Argentina received two s ("Santa Cruz" class) during the 1980s. Ten s were purchased by India in the 1980s and 1990s (), along with the INS "Chakra" in 2011. Two s have been commissioned by Chile, while Brazil has four and India has six ships ordered or under construction. Nine Type 214 submarines ("Son Won-il" class) are commissioned, building, or planned by South Korea to supplement its force, while Greece is replacing its aging "Glavkos" class with four Type 214 submarines ("Papanikolis" class), and Turkey will be replacing early "Atılay"-class ships with six Type 214 submarines.
