Description

The Japan Maritime Self-Defense Force (JMSDF) 30FFM, formerly known as 30DD or 30DX, is a class of multipurpose frigates intended to conduct maritime surveillance in waters surrounding Japan. These frigates will be powered by a Rolls-Royce MT30 gas turbine allowing a top speed of 30 knots along with two diesel MAN engines in a Combined Diesel and Gas (CODAG) arrangement. The weapon system will include eight XSSM supersonic anti-ship missiles, one SeaRAM close-in weapon system and 32 ESSM surface-to-air missiles as well as a 127mm Mark 45 Mod 4 naval gun. The ships will be equipped with 8 or 16 vertical launching system (VLS) cells that may home anti-submarine rockets as well as a longer range surface-to-air missiles in addition to the ESSM missiles (four in each cell). The 30FFM class frigates will be provided with flight deck and hangar. The ship will also feature a dual-band advanced radar system FCS-3A and electro-optical sensors to operate in challenging environments such as littoral waters. Hull-mounted sonar and variable depth sonar (VDS) will be provided as well. Besides, these frigates will be provided with a domestic cooperative engagement capability similar to the US Navy CEC allowing to improved performance through sharing of target data. The 30FFM class frigate program carried out by Mitsubishi Heavy Industries and Mitsui Bussan comprises eight 3,900-ton vessels with the lead ship construction to start in 2019 to be commissioned in 2022. The JMSDF may order between 22 and 28 such ships two per year to counter the Chinese Navy buildup in the South China Sea. Finally, Japan decided to build 12 ships and another 12 ships of an improved variant.
