Project Kahu
Project Kahu was a major upgrade program for the A-4K Skyhawk attack aircraft operated by the Royal New Zealand Air Force (RNZAF) in the mid-1980s. Prior to the implementation of the upgrade, the A-4K Skyhawks, which had served with the RNZAF since 1970, had become dated compared to modern jet fighter aircraft.The project was named after the Māori-language name for the New Zealand swamp harrier.
