The success of this pilot program brought on line the Hemet-Ryan Helitack Base using a full-time contract helicopter staffed with three captains and nine firefighters operating out of Ryan Air Attack Base. In 1992 Cal Fire acquired several larger Bell UH-1H helicopters with Hemet-Ryan Helitack receiving one of the first buildups. A year later, the OV-10 replaced the Cessna 337 as Air Attack 310 based at Ryan. In June 2001, Cal Fire replaced the older S-2As at Ryan with Tanker 72 and 73. The new tankers are S-2F3AT Turbine Tanker conversions with upgrades including constant flow 1200 gallon tanks and turbine engines allowing for better capabilities and performance. Future of Ryan Air Attack In June 2007 The Hemet-Ryan Airport was approved $2.5 million from the Riverside County Board of Supervisors and over $25 million from the state for the redevelopment of the air-attack facilities. The upgrades would include extending the runway from to to accommodate heavier firefighting aircraft such as the MAFFS C-130. The runway expansion would take place on the southwest portion of the complex and require re-alignment of bordering Stetson Avenue and Warren Road. The new base would also include a , 22-bed barracks building, a three-bay vehicle storage facility and shop; a , two-story operations building containing pilot facilities, administration and dispatch center; a , two-bay open-shade canopy and an helicopter/ OV-10 enclosed hangar. Also planned are new public and secured staff parking areas, six fire-retardant loading pits to handle inter-agency aircraft, along with equipment tanks, pumps and piping used to mix and deliver fire retardant. Because of critical need, the strategic location of the base and proven performance and handling of large wildfires, Cal Fire and the state consider the project top priority in the list of firefighting capital improvements. Construction was to begin in 2008, but as of 2010, Cal Fire is still waiting for the promised state funds. Meanwhile, Cal Fire has been drawing plans and preparing to open the project to contractor bidding, and the Riverside County Economic Development Agency has agreed to manage the project. Facilities Apart from hosting Cal Fire air attack operations, the Hemet-Ryan is also home to a Riverside County Sheriff's Department aviation unit. In August 2010 the airport became home to an emergency medical helicopter operated by Mercy Air. The airport also hosts a biennial air show with the next one being in 2011. In 2008 the airport
