Design and development
The prototype S-434 first flew on 18 December 2008 at Horseheads, New York. The S-434 evolved from the S-333, and has many features developed for the MQ-8 Fire Scout. It shares its cockpit layout with the S-333, which gives the crew very good visual capacities and handling characteristics.[citation needed]
On June 15, 2009, Sikorsky announced the delivery of the first two S-434s to Saudi Arabia's Ministry of the Interior, the first of a total of nine.[1]
