ShinMaywa US-2
The ShinMaywa US-2 is an amphibious SAR aircraft produced by the Japanese aircraft manufacturer ShinMaywa Industries . In the Japanese Marine Self-Defense Forces it is intended to replace the Shin Meiwa PS-1, which has been in service since 1971, or the modernized version US-1A in the SAR role.
development
The US-2, initially developed as US-1A Kai (Kai = improved), was, like its predecessor US-1A, specially developed for the needs of the marine self-defense forces. It is a direct further development of the US-1A. The first prototype began flight tests on December 18, 2003, the second prototype followed in mid-2004.
ShinMaywa is currently trying to market a civilian version of the US-2 as a fire fighting or passenger aircraft . The extinguishing version would have a water capacity of 12,000 l. A realization is rather unlikely, since civil customers would rather opt for more economical aircraft such as the Canadair CL-415 .
Users
- Japan
- The Marine Self-Defense Forces plan to procure a total of 14 US-2s. The first series machine flew for the first time on December 15, 2008 and was transferred to the 71st season in Iwakuni in February 2009 . A total of seven series machines have been firmly ordered so far (as of July 2010). They will completely replace the US-1A.
- India
- The first export customer is the Indian Navy , which procures 12 US-2i; it is Japan's first material export for a military customer after 1945.
construction
The construction of the US-2 is largely based on the previous model PS-1 or US-1A. Although both patterns look almost the same, the essential parts of the airframe on the US-2 are completely new designs. The wings and parts of the now pressurized fuselage are made of composite materials . The resulting weight savings lead to a take-off distance reduced by half. New economical AE2100 engines from Rolls-Royce / Allison with an output of 3425 kW each with six-blade propellers made of composite materials instead of three-blade propellers, a new additional turbine CTS-800-4K with 1015 kW output from Rolls-Royce / Honeywell for boundary layer control and an Ocean Master 100 search radar from Thales as well as a FLIR are installed. All avionics subsystems and the cockpit are also new.
