The introduction of the Mk 9 along with TACR1 and new foams began a new era in crash fire-fighting. Because of the nature of the flouroprotein foam it was delivered as premix, then aspirated at the monitor and through foam making branch-pipes.

Having a large tank capacity, the Mk 9 did not rely upon having extra water delivered from DP trucks, and its impressive jet throw from the monitor made it a powerful tool in fighting large aircraft fires quickly and effectively.  The only down side came when crash crews were reduced in size following the introduction of the Mk 9.
