The U.S. Air Force said on Sept. 5 that it awarded Poway-based PKL Services Inc. a one-year, $11.9 million contract modification for aircraft maintenance and operation services.

The client is the Republic of Singapore.

Work will be performed at Mountain Home Air Force Base, on the Snake River in the southwest corner of Idaho.

The 366th Contracting Squadron at Mountain Home Air Force Base awarded the deal.

It’s not the only foreign military sale contract that went to PKL this month.

Late last week, the Air Force announced that PKL was receiving an indefinite-delivery, indefinite-quantity contract for maintenance training for Saudi Arabian air crews servicing that country’s fleet of F-15 aircraft. The five-year contract has a ceiling value of almost a half-billion dollars. Work will be done in Saudi Arabia.

Terry Robling, a retired Marine Corps lieutenant general, is PKL’s chief executive. Sam Flores is the Poway company’s owner and chairman.
