The ShinMaywa US-2 is a Japanese large STOL amphibious aircraft designed for air-sea rescue (SAR) work. Operated by the Japan Maritime Self-Defense Force, the US-2 is scheduled to replace the older Shin Meiwa US-1A in Japanese service. It can be used as fire fighter taking 15 tonnes of water.[1]

Design and development

With the Shin Meiwa US-1A fleet introduced in the 1970s beginning to reach the end of its service life, the JMSDF attempted to obtain funding for a replacement in the 1990s, but could not obtain enough to develop an entirely new aircraft. Therefore, in 1995, ShinMaywa (as Shin Meiwa was by then renamed) began plans for an upgraded version of the US-1A, the US-1A kai (US-1A 改 - "improved US-1A"). This aircraft features numerous aerodynamic refinements, a pressurised hull, and more powerful Rolls-Royce AE 2100 engines. Flight tests began on December 18, 2003. The JMSDF purchased up to 14 of these aircraft, which entered service as the ShinMaywa US-2.

Operational history

The aircraft is currently operated by the 31st Fleet Air Wing (71st Air Force, 71st Flight Squadron) at Iwakuni air base and Atsugi air base.

In April 2015 aircraft 9905 was involved in an accident.[2] The aircraft was on a training mission near Cape Ashizuri in Shikoku and four crew members were injured.[3]

Export

The Indian Navy has a requirement for 12–18 US-2 Amphibious Search and Rescue aircraft at a cost of $USD1.65 billion. It is expected that these amphibious aircraft will be stationed in the Andaman and Nicobar Islands.[4][5] In October 2016, ShinMaywa reduced the price to around $USD 113 million per aircraft.[6] There were expectations that a contract for the order would be signed in November 2016,[7] but it was deferred by the Indian defence minister Manohar Parrikar.[8][9] In March 2018, Japanese ambassador to India Kenji Hiramatsu told The Hindu Business Line that talks were still in progress.[10]

There have also been reports that Thailand is interested in purchasing the aircraft.[11]

Indonesia is another prospective customer.[12]

Following deadly fires in the Attica Region of Greece in July 2018, the Greek government reportedly seeks to order US-2 to replace their aging firefighting fleet.[13]
