Pratt & Whitney has renewed its performance-based logistics (PBL) contract to maintain F100 engines that power Republic of Korea Air Force (ROKAF) fighters.

The contract was signed with Seoul’s Defense Acquisition Program Administration (DAPA) and is valued at $355 million, says P&W parent RTX.

The contract covers the engines that power South Korea’s fleet of Boeing F-15s and Lockheed Martin F-16s.

This is the third consecutive PBL since 2012 and will cover sustainment work through the second half of 2027.

“For just over a decade, we have worked with DAPA on these performance-based logistics contracts to establish a more strategic sustainment solution for the ROKAF fighter fleet,” says Chris Johnson, vice-president of fighter and mobility programmes at P&W.

“These contracts are a win-win for both customers and industry because they offer more efficient affordability and availability.”

Cirium fleets data indicates that the ROKAF has 167 in-service F-16C/D fighters. Of these, 134 are being upgraded to an improved F-16V standard.

The ROKAF also operates 59 F-15K “Slam Eagles” with an average age of 15.3 years. In late 2022 DAPA announced a performance update project for the F-15K fleet that will run from 2024-2034.

The twin-engined fighters will receive a new active electronically scanned array radar, mission computer, and electronic warfare suite.
