Whirlwind HAR.9

Westland judged that turbine engines were powerful and reliable enough to incorporate the Rolls Royce Gnome engine into the Whirlwind Srs.3. This major version needed a redesigned nose section to accommodate the larger engine in a position to make maintenance more convenient. The first Series 3 (a HAR.9) flew in Feb 1959 and was also the basis of the dedicated RAF Search and Rescue HAR.10 and HCC.10 VIP conversion

Converted HAS.7 powered by Bristol Siddeley Gnome engine and outifitted for SAR for Royal Navy, 15 conversions of HAS.7. [One source stated 18 conversions.]
