This class was planned to replace the earlier and possess both ASW capability as the successor of the and ASuW capability as the successor of the , but there are many enhancements as follows: ; Introduction of stealth technology. : This class is the first combatant ship of the JMSDF with stealth technology. Their superstructure has traditional vertical surfaces, but their hulls are angled to reduce their radar cross section. ; Enhanced electronics. : This is the first destroyer escort class with the Naval Tactical Data System and OYQ-7 combat direction system. It is also the first destroyer escort class which has ECM capability with the OLT-3 jammer. ; Modified weapon systems. : The Short Range Air Defense system comprises the OPS-14 air-search radar, the OPS-28 surface search and target acquisition radar, one Otobreda 76 mm rapid-firing gun controlled by the FCS-2 fire-control system and Phalanx CIWS. The OPS-14 is the Japanese equivalent of the American AN/SPS-49 radar, and the OPS-28 is the equivalent of the American TAS Mk.23. Phalanx CIWS has given the ships an improved self-defence capability against anti-ship missiles. Mk.31 RAM GMWS Point Defense Missile System was planned, but it is not installed yet. : The ASW system comprises an OQS-8 hull-sonar (Japanese equivalent of the American DE-1167), ASROC anti-submarine rocket from the Type 74 octuple launcher (Japanese license-built version of the American Mark 16 GMLS) and lightweight ASW torpedoes from two HOS-301 triple torpedo tubes. A Tactical Towed-Array Sonar System was planned but it is not installed yet. The JMSDF intended to build eleven ships of this class, but finally, only six were built because s started deploying in distinct forces. All six vessels of the class are named after World War II cruisers. == Ships in the class == 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Abukuma-class destroyer escort」の詳細全文を読む スポンサード リンク
