Cal Fire CDF S-2T Trackers

Grumman / Marsh Aviation S-2T / S-2FAT Turbo Trackers in service with Cal Fire (formerly CDF) Cal Fire (formerly CDF) operates 23 of the upgraded S-2FAT Turbo Trackers rebuilt by Marsh Aviation in Mesa, AZ. These aircraft are the original Grumman airframes that have been gutted of all wiring, plumbing, and other internal parts and rebuilt as new aircraft with turbine engines. With the new Turbines and the rock solid Grumman "Iron Works" airframe, these aircraft will last indefinitely and are now registered as Marsh built, rather than Grumman, due to the total rebuild. The last 3 of the Marsh aircraft were delivered in 2005. Cal Fire aircraft are all registered to the USDA Forest Service. It should be noted that Cal Fire also retains several of the old reciprocating engine Trackers which may also have the same Tanker numbers as the new S-2Ts. The 23 Turbo Trackers are listed below in three different ways. Photos of all these aircraft can be found at my USA Tracker Page. Listed in numerical order by FAA Registration
