Over the next four months the Royal New Zealand Air Force (RNZAF) will take delivery of four Mitsubishi MU-2F fixed-wing aircraft and six Kaman SH-2F Seasprite helicopters. The Air Force has been looking into revitalizing its aging training aids at RNZAF Ground Training Wing (GTW) Woodbourne near Blenheim to ensure its current and upgraded aviation fleet can meet the needs of New Zealand into the future. The first two Mitsubishi MU-2Fs are due to fly in to Woodbourne from Texas, USA this weekend or early next week, depending on the weather. The second two aircraft are undergoing pre-flight maintenance and are scheduled to leave the USA early August. The six Kaman SH-2F Seasprite helicopters have been in storage in the Arizona desert for 14 years and are due to be shipped to New Zealand late 2009. The aircraft will be used by the GTW for technical trade training. They will replace aging de Havilland Devon aircraft and Bell 47 Sioux helicopters.
