Río Hato continued to be used by the U. S. Army Air Force (USAAF) then by the U. S. Air Force (USAF) until closed in 1948, but remained in use as an USAF axillary military landing field for Howard AFB until the late 1990s.

After closure, the Panamanian Air Force (PAF) and Panamanian Defense Force (PDF) occupied the area.

On December 20, 1989 during "Operation Just Cause" Río Hato was also the first target for the newly introduced F-117 Nighthawk stealth fighter tasked with bombing a barracks housing two companies housing Battalion 2000, an elite unit known to be fiercely loyal to Panamanian Dictator Manuel Noriega. The F-117 dropped two large 2,000 pound Mark 84 bombs dubbed "the Hammer".

At 1:00am, the U. S. Army 75th Ranger Regiment 2nd Battalion and 3rd Battalions (TF RED ROMEO) made a paratrooper jump from C-130s to capture Rio Hato and neutralize infantry from the 6th Panamanian Defense Force (6th PDF) and 7th Panamanian Defense Force (7th PDF). Both infantry companies had been alerted, and fired on the C-130s with small arms. Despite PDF resistance, the battalion assembled, attacked the barracks and established an airhead. By morning, the Rangers accomplished their mission, captured 250 prisoners and cleared the airfield for use by the U. S. for future operations.

In 2011 the Government of Panama gave the order to rebuild the airport, rehabilitate the runway, the airport terminal, and construction of a tunnel for the Carretera Panamericana that currently crosses the runway. The award of this project, which has a cost of $53.2 million dollars, was done through a public bidding process, this project will be supervised by the Ministry of Public Works (MOP) and the Civil Aviation Authority (CAA) and is expected to last 14 months.

The new airport named "Cap Scarlett Martínez Airport" was dedicated on November 13, 2013 by President Martinelli as a small airport with a single runway oriented 34/16 measuring 4,380' x 164' surfaced with asphalt. Airport codes: IATA: RIH, ICAO: MPSM. The new airport helped reduce traffic at Panama City’s Tocumen International Airport. It will serve to boost tourism along the Pacific beaches where beach resorts and condos are located.
