Abukuma-class destroyer escort


The Abukuma-class destroyer escort is the general-purpose destroyer escort of the Japan Maritime Self-Defense Force. It is the successor of the earlier.

Design

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 Yubari class, 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.

Electronic warfare

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.

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, ASROC anti-submarine rocket from the Type 74 octuple launcher 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.
