Airborne Mine Countermeasure System Delivered to Japan

The Japan Maritime Self Defense Force has taken delivery of the first Airborne Mine Counter Measures (AMCM) equipped MCH-101 from Finmeccanica – AgustaWestland and Kawasaki Heavy Industries (KHI).

The KHI MCH-101, a licence built version of the AgustaWestland AW101 helicopter, is equipped with the Northrop Grumman AN/AQS-24A airborne mine hunting system and the Northrop Grumman AN/AES-1 Airborne Laser Mine Detection System (ALMDS). Together these systems provide a complete surface-to-bottom mine detection capability.

The AW101/MCH-101 is one of only two helicopter types capable of towing the AN/AQS-24A and the only modern helicopter type.

The development of the AMCM variant of the AW101/MCH-101 has been led by Kawasaki Heavy Industries, as prime contractor, with AgustaWestland providing technical support. KHI has responsibility for system integration and design of the AN/AQS-24A carriage, deploy, tow and recovery system that is installed in the cabin. AgustaWestland in addition to providing technical support also modified the aircraft’s Automatic Flight Control System (AFCS) to be able to perform coupled towing patterns with the AN/AQS-24A.

The AN/AQS-24A is the only operationally proven, high speed airborne mine hunting system in the world. It features a high-resolution, side scan sonar for real time, detection, localization and classification of bottom and moored mines at high area coverage rates and a laser line scanner to provide precision optical identification of underwater mines and other objects of interest.

The AN/AES-1 uses pulsed laser light and streak tube receivers housed in an external equipment pod to image the entire near-surface volume potentially containing mines. The ALMDS pod is mounted on the port weapon carrier and data is displayed on the cabin mission console.

Following the handover ceremony at Kawasaki’s Gifu factory on 27th February, the Japan Maritime Self Defense Force aircraft was delivered to Iwakuni where it will perform evaluation trials with the 51st Experimental Squadron before entering operational service in 2016.
