We call them U209pn because in the begining of the international contest hdw presented the u209 but then to defeat the scorpene the germans changed the characteristics now we will have a true u214 AIP model similar to the greeks but a little longer i think because we put a separation in two halfs (Kursk acident inspirantion).
