Bedford Pyrene Mk8

The Mk 8 was introduced to the RAF in 1972. In terms of design it was different to previous post war RAF crash trucks in that it had an auxiliary engine to drive the fire pump instead of using the prime mover via a power take off (PTO). It was not a major foam vehicle and classed as a primary 2 truck for use on smaller airfields or on larger airfield augmenting the major foam trucks. It was also capable of water production for use in the domestic fire fighting role. It carried a crew of 3.

The last ones were taken out of service in1992
