AFIMSC executes $9.1B in FY23; receives $4.6B in multiyear appropriations

JOINT BASE SAN ANTONIO-LACKLAND, Texas – The Air Force Installation and Mission Support Center had another record year in FY23, executing $9.1 billion in operation and maintenance funds and receiving $4.6 billion across other multiyear appropriation programs that support Air and Space Forces missions around the globe.

“Commanders at all levels across the Department of the Air Force rely on our team to fund their mission-critical requirements at the right time and at the right level,” said AFIMSC Commander Maj. Gen. John Allen. “Our dedicated resources team – and the experts they work with throughout our center – raise the bar every year, producing and managing an effective budget with sound distribution and execution strategies. They make sure commanders have what they need to maintain a ready and lethal force and deliver a better quality of life for Airmen, Guardians and families.”

AFIMSC’s O&M budget supports all Air Force and Space Force installations. FY23 funding included: 

  • $3 billion in must-pay requirements including installation utilities, environmental quality program, and international agreements
  • $2.4 billion in other base operating support requirements to include base maintenance contracts, fire and emergency services, and quality of life projects related to Airman and family services including dining facilities, child and youth programs, and fitness and morale, welfare and recreation activities
  • $2.1 billion in decentralized facilities, sustainment, restoration and modernization 
  • $1.4 billion in installation construction tasking order funding
  • $200 million in natural disaster rebuilding efforts at Tyndall Air Force Base, Florida 

In addition to O&M funds, AFIMSC received more than $4.6 billion in multiyear appropriations:

  • $3.9 billion in military construction
  • $365 million in military family housing 
  • $175 million in base realignment and closure programs
  • $145.1 million in procurement
  • $21.5 million in research, development, test and evaluation for critical programs including airfield damage repair and airfield protection


The center navigated several obstacles to achieve a successful fiscal year, said Lt. Col. David Osterhaus, AFIMSC Resource Management Analysis Division chief. 

“The team conquered a variety of challenges during FY23, starting with a significant base operating support unfunded requirement and a bill for natural disaster recovery at Tyndall. Emergent must-pay requirements for utility increases, Pacific Deterrence Initiative support, Ebbing Field and Typhoon Mawar recovery at Andersen Air Force Base, Guam, further stressed our limited funding,” Osterhaus said. 

The Air Force selected Ebbing Field at Fort Smith, Arkansas, to be the new Foreign Military Sales Program Pilot Training Center in March and the funding supports basing and bed-down operations there.

Teamwork and close collaboration with subject matter experts throughout the year ensured the center was able to overcome the fiscal challenges that arose to make the best use of limited resources, he said. 

“It begins as a partnership with AFIMSC enterprise managers through validation and allocation processes and culminates in AFIMSC commander-approved strategies,” Osterhaus explained. “We use the strategies and approved priorities to collaborate with the Air Force to gain additional funds for mid-year and end-of-year shortfalls. The management analysis division branches also work together throughout the year performing trend analysis, leading problem-solving sessions with installations and primary subordinate units, and executing the end-of-year war room.

“Our installations, detachments and PSUs did a phenomenal job this year, executing the resources they were given to support the mission,” he said.
