Four Republic of Singapore Air Force (RSAF) CH-47 Chinooks from the Peace Prairie detachment in Grand Prairie, Texas arrived on site on 31 Aug 2017 to assist in the Texas Army National Guard's Hurricane Harvey disaster relief operations. The RSAF Chinooks will contribute to the relief efforts by transporting evacuees, as well as deliver equipment and supplies.

A total of 34 RSAF personnel from the Peace Prairie detachment, comprising pilots, aircrew and engineers, have been deployed for this mission. This effort follows the acceptance of Singapore's offer of assistance by U.S. President Donald Trump.

Singapore Prime Minister Lee Hsien Loong described the move as “a small gesture to express our appreciation and gratitude to the U.S. and in particular the State of Texas, which have been good hosts for our Peace Prairie detachment.”

The RSAF's Peace Prairie detachment has worked together with the Texas Army National Guard in the past, including relief operations after Hurricane Katrina in 2005, fire-fighting and flood relief operations in Texas in 2000, and Hurricane Floyd relief operations in North Carolina in 1999.

Peace Prairie — one of five RSAF training detachments in the U.S. — was set up in 1996, following an initial order for six CH-47 Chinooks. The RSAF currently operates a total of 6 CH-47D and 10 CH-47SD Chinooks and last year announced plans to replace some of the older models with CH-47Fs.
