MH-139A

The MH-139A program is designed to replace the Air Force's existing UH-1N aircraft fleet, addressing capability gaps in speed, range, endurance, payload capacity, and self-protection. This initiative is part of the Air Force's broader nuclear enterprise reform efforts and aims to enhance vertical airlift capabilities. It supports the operational requirements of the Air Force Global Strike Command (AFGSC), Air Force Reserve Command (AFRC), and Air Education and Training Command (AETC). The AFGSC serves as the lead command and operational capability requirements sponsor for this program.

The primary objective of the MH-139A program is to procure a total of 42 helicopters along with training devices and associated support equipment. This effort includes site activation support, depot activation, interim supply support, and interim contractor support. The program aligns with Title 10 U.S.C. Chapter 9A, Sec 240-D requirements for a full financial audit. Key milestone dates include Initial Operational Test & Evaluation (IOT&E) in June 2024 and Full Rate Production (FRP) in March 2025.

Additionally, the MH-139A program addresses Diminishing Manufacturing Sources (DMS) issues by integrating common assets into existing depots. The Depot Source Of Repair (DSOR) decision designates Fleet Readiness Center East for dynamic and structural hardware components, while Ogden ALC, Warner Robbins ALC, and Oklahoma City ALC handle LRU hardware and software. Warner Robins ALC will focus on software sustainment and cryptographic work. The sustainment business case analysis has shifted training systems to contractor performance.

The procurement strategy involves a low-rate initial production lot of eight aircraft in FY25. This includes comprehensive support elements such as training, site activation support, other government costs, program support costs, depot stand-up costs, and interim contractor support. The manufacturing lead time for these helicopters is structured to ensure timely delivery to meet operational needs across various commands within the Air Force.
