About this IDV

The federal contract IDV award is a single-award Indefinite Delivery Contract (IDC) between the U.S. Army's Aviation and Missile Command (AMCOM) and The Boeing Company, a major defense contractor, for the overhaul and production of mechanical transmissions for the CH-47F Modernized Cargo Helicopter (CH-47F Block II) program. This $49.7 million IDC supports the Army's efforts to modernize and sustain its fleet of CH-47F Chinook heavy-lift cargo helicopters through aircraft production, component upgrades, and comprehensive maintenance to ensure operational readiness.

The contract includes two firm-fixed-price delivery orders awarded to Boeing. The first order, valued at $11.9 million, is for the overhaul of the CH-47F Block II mechanical transmission, with key subcontractor Rosemount Aerospace Inc. providing specialized aerospace components. The second order, worth $12.7 million, is for the production of additional mechanical transmissions for the CH-47F Modernized Cargo Helicopter program. These contract actions do not utilize any set-aside designations, indicating full and open competition. The period of performance extends through 2026, demonstrating the long-term nature of the CH-47F Chinook modernization and sustainment efforts supported by this IDC.
