The Oshkosh P-19R is an Aircraft Rescue and Fire Fighting (ARFF) vehicle and it was selected by the U.S. Marines in 2013. The first delivery occurred in June 2017, Initial Operating Capability (IOC) followed in February 2018, and in service the P-19R serves as a first-response vehicle in aircraft fire emergencies at military bases and expeditionary airfields. Leveraging three decades of proven P-19 experience with advanced firefighting technology, the Oshkosh P-19R Aircraft Rescue Fire Fighting (ARFF) vehicle delivers cutting-edge on-road and off-road firefighting capabilities. The P-19R is also equipped with Oshkosh’s Command Zone integrated control and diagnostic system originally developed for the company’s commercial fire-fighting vehicle in 1999. Command Zone is a computer-controlled, electronics technology that operates and diagnoses all major vehicle networks. The backbone of the system is multiplexing technology that allows vehicle components to work in concert, streamlining diagnostic and troubleshooting efficiencies. Both a local and remote monitoring system, it allows real-time access to critical vehicle information via command and control networks, laptops, on-board display screens or hand-held personal digital devices.

The P-19R is based on a conventional C-section rigid chassis, the wheelbase of which is 4.851 m. Motive power is provided by a rear-mounted transverse 15.2-litre Caterpillar C15 six-cylinder in-line turbocharged, water-cooled four-stroke diesel, developing 600 hp (448 kW), this coupled to an Allison 4700 SP seven-speed fully automatic transmission and Oshkosh 35000 Series single-speed transfer case. This set-up is shared with Oshkosh’s Logistic Vehicle System Replacement (LVSR) which is also in service with the Marines. Suspension is Oshkosh TAK-4 fully independent double wishbone all-round, and by coil springs with 16-inches of independent wheel travel. TAK-4 suspension is fitted to the Marines’ LVSR and Medium Tactical Vehicle Replacement (MTVR) fleets, and is also fitted to the Oshkosh M-ATVs and upgraded Cougar MRAPs that are being retained by the Marines post-Afghanistan. The P-19R is fitted with Michelin XZL 16.00 R 20 tires. A Dana central tire inflation system (CTIS) is fitted, this allowing the driver to adjust tire pressures to suit the terrain being crossed.

On the underside of the P-19R there are nozzles that can discharge 56 liters of water and foam to extinguish a fire or fuel spill underneath the vehicle. In front of the vehicle Oshkosh has installed nozzles that spray water and foam on the windshield to keep it cool.
