ShinMaywa US-2

https://en.wikipedia.org/wiki/ShinMaywa_US-2

The ShinMaywa US-2 (formerly Shin Meiwa) is a Japanese large STOL amphibious
aircraft designed for air-sea rescue (SAR) work. The US-2 is scheduled to
replace the older Shin Meiwa US-1A.

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 ? - "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.

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

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. As of October
2016, a contract has not been signed by India, but ShinMaywa has reduced the
price to around $USD 113 million per aircraft.

There were expectations that a contract for the order would be signed in
November 2016, but it was deferred by the Indian defense minister Manohar
Parrikar.

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

Indonesia is another prospective customer.
