Royal New Zealand Air Force to Upgrade P-3K Orion

The New Zealand Ministry of Defence has revealed the total cost of the seven-year project is projected to be $332.3 million.
The P-3K Orion Upgrade Project would finish halfway through this year with only a software upgrade to go.
Equipment such as computers, mission systems, radar systems, wiring and antennas had been upgraded.
"The configuration of the aeroplane it was quite modern compared to some P3s in the world, but the computing power that was put in the original upgrade back in the 80s/90s was about the power of a commodore 64."
The planes were first introduced into service in 1965.
