DRG Expands O-Level Maintenance

OKLAHOMA CITY (Sept. 18, 2023) – Delaware Resource Group of Oklahoma LLC on Oct. 1 will kick off its support on an aircraft maintenance services contract with the 80th Flying Training Wing (FTW) at Sheppard Air Force Base (AFB) in Texas.

DRG will serve as a subcontractor to M1 Support Services LP on this contract, which continues to expand DRG’s presence in the O-level maintenance sector.

“This is a huge step in diversifying our organization for the future,” said DRG Chief Executive Officer Brian Busey. “This effort could bring up to 25 new team members to DRG through 2029.”

The Sheppard AFB Aircraft Maintenance Program consists of aircraft and equipment maintenance functions necessary to support the Sheppard AFB Euro-North Atlantic Treaty Organization (NATO) Joint Jet Pilot Training (ENJJPT) Program. The primary mission of the 80th Flying Training Wing is to produce the world’s finest NATO pilots with the skills and attitude to succeed in fighter aviation and have the vision to be the world’s premier combat pilot training program. The 80th FTW operates one of the Air Force’s busiest joint-use airfield outside of a combat zone. The wing delivers more than 200 Undergraduate Pilot Training graduates annually, along with 150 graduates of Introduction to Fighter Fundamentals and 75 Pilot Instructor Training graduates.

The Sheppard AFB Aircraft Maintenance contract is in addition to the Sheppard Trainer Maintenance contract, which DRG serves as a subcontractor to M1. That program kicked off in November 2022 and runs through March 2028.

Founded in 2002 in Oklahoma City, DRG has become a leading global training service contractor specializing in the aerospace defense industry. DRG is owned and operated by the Busey family.
