FY28 KC-46A AIRCRAFT BEDDOWN INFRASTRUCTURE PROGRAM

REQUIREMENTS OVERVIEW

1. SCOPE

The KC-46A Aircraft Beddown Infrastructure Program at Altus AFB, Oklahoma, delivers comprehensive flight-line, industrial maintenance, and advanced aircrew flight simulator training facilities necessary to support the 97th Air Mobility Wing (97 AMW) - the Department of the Air Force’s sole formal training unit for heavy mobility aircraft. The consolidated capital program modernizes the installation’s infrastructure to replace Eisenhower-era KC-135 operations with the next-generation KC-46A Pegasus tanker while sustaining concurrent training and maintenance for C-17 and legacy fleets.

The program delivers three primary facility complexes along with associated airfield civil site infrastructure:

· Aircraft Maintenance Facilities

· KC-46A Aircraft Maintenance Hangar (General Maintenance): A fully enclosed, single-bay aircraft general maintenance facility (Cat Code 211-111) engineered to support maintenance tasks and provide inclement weather protection for multi-craft fleets (KC-46A, KC-135, C-17, and C-137). Structural components include reinforced concrete foundations, a structural steel frame and standing seam metal roof system, insulated metal wall panels, and high-strength concrete floor slabs. Interior functional space integrates personnel support areas, flight chief/production supervisor offices, expediter offices, break rooms, locker/shower rooms, tool rooms, laser rooms, hazardous material (HAZMAT) storage, a dedicated hazardous waste collection system, and Consolidated Tool Kits (CTK) suites. Airfield site work includes heavy-duty concrete pavement, taxiway tie-ins, aircraft wash racks, exterior lighting, and utility distribution.

· KC-46A Multipurpose Hangar (Corrosion Control & Open-Tank Fuel Cell Maintenance): A highly complex, fully enclosed single-bay hangar (Cat Code 211-159) engineered specifically to execute high-risk corrosion control operations (sanding, washing, aircraft depainting/painting) and open-tank fuel cell maintenance. Structural features include steel framing, insulated metal walls, and explosion-resistant construction. Functional spaces encompass paint storage and mix rooms, clean rooms, blast booths, sanding/filter storage, dedicated fuel tank repair and tool storage shops, breathing air systems, specialized industrial ventilation/exhaust systems, hazardous waste collection, and administrative personnel spaces.

· Flight Crew Training & Simulator Facility

· KC-46A Simulator Facility Phase 4 (Flight Training Center Expansion): An expansion to the existing Flight Training Center (FTC) (Cat Code 171-212) designed to support classified training operations for KC-46A aircrews. The expansion adds dedicated high-bay simulator bays and support space to house:

· High-bay Weapons System Trainers (WST) (full-motion flight simulators);

· Boom Operator Trainers (BOT) and Part Task Trainers (PTT);

· Integrated bridge and overhead servicing cranes for simulator maintenance and hydraulic/motion platform equipment removal;

· Specialized mechanical, electrical, plumbing (MEP), and fire detection and suppression systems, including redundant, high-efficiency Computer Room Air Conditioning (CRAC) / precision HVAC systems for computer rooms, simulator visual systems, and motion equipment;

· Dedicated classroom spaces, flight briefing/debriefing rooms, and administrative offices;

· Secure areas designed, engineered, and constructed to strict Intelligence Community Directive (ICD) 705 Sensitive Compartmented Information Facility (SCIF) physical, acoustic, and tempest security standards;

· Associated heavy-duty exterior pavements, access driveways, delivery bays, and personnel parking areas.

· Associated utility hookups and extensions.

· Enabling Civil Infrastructure & Demolition

· Aircraft Refueler Vehicle Parking Area Relocation: Site preparation for the General Maintenance Hangar requires the complete relocation and replacement of an existing 68,620 SF aircraft refueler parking yard. Scope includes high-strength concrete paving, dedicated secondary containment, security fencing, lighting, and an integrated environmental stormwater control and oil-water filtration system.

· Liquid Oxygen (LOX) Plant Relocation: Enabling work for the Multipurpose Hangar requires the decommissioning, demolition, and off-site reconstruction of the active base LOX facility. The replacement facility encompasses specialized oil-free/hydrocarbon-free concrete paving, cryogen storage pads, an overhead weather protection structure, security fencing, hazardous gas detection, and dedicated utility connections.

· Demolition: Demolition of three aging flight-line structures (approx. 155 SM total) and existing asphalt/concrete parking areas to clear the building footprints.

All facilities will be designed and constructed as permanent construction in accordance with UFC 1-200-01 (DoD Building Code), UFC 4-010-01 (DoD Minimum Antiterrorism Standards for Buildings), and the installation's Architectural Compatibility Plan.

The table below provides approximate gross square footages and metric program scopes:

2. TIMING, LIMITATIONS, AND PHASING:

· Sustained Mission Readiness:

· Altus AFB operates the DoD’s only formal training pipeline for mobility flight crews and technicians. Active flight operations, simulator schedules, and flight-line refueling operations must proceed without interruption throughout construction.

· Critical Enabling Sequencing:

· Refueler Lot Replacement: The replacement 68,620 SF refueler parking lot and stormwater containment facility must be fully operational, inspected, and commissioned before the existing lot can be demolished for hangar construction.

· LOX Facility Replacement: The replacement LOX facility must be fully commissioned, safety-certified, and operational prior to taking down the existing plant and canopy to prevent fueling capability deficits.

· Key Design and Award Milestones:

· Design 35% / pre-design target: 1 July 2026

· Construction Begins: Fiscal Year 2027 / Early FY28

· Simulator Facility Phase 4 must coordinate milestone deliveries with AFLCMC/WFE and simulator contractors to ensure bay readiness, power conditioning, and SCIF accreditation align with device deliveries.

3. MANDATE FOR INNOVATION:

· Life Cycle Cost Analysis (10 CFR 436 Subpart A): All proposed structural systems, exterior building enclosures, and major building heating, ventilating, and air conditioning (HVAC) systems must be justified through a comprehensive 25-to-30-year Life Cycle Cost Analysis (LCCA) complying with 10 CFR 436 Subpart A (Methodology and Procedures for Life Cycle Cost Analyses). Design selections must systematically demonstrate lowest total ownership cost regarding maintenance frequency, operational energy consumption, and durability in Southwest Oklahoma climatic conditions.

· High-Performance & Sustainable Building Requirements (HPSB): Facility designs must comply with UFC 1-200-02 (High Performance and Sustainable Building Requirements) and the Guiding Principles for Sustainable Federal Buildings. Proposals must include an executed Air Force Sustainability Requirements Scoresheet, incorporating energy metering, advanced water conservation, low-impact development (LID) stormwater controls, and high-efficiency HVAC and lighting technologies.

· Accelerated Milestones & Early Work Packages: Innovation initiatives should evaluate phased execution strategies, including early site demolition packages (existing parking, legacy structures, and LOX/refueler relocation), early structural steel mill orders, and pre-engineered components that enable the project team to meet the targeted early FY28 construction starts.
