The Corpus Christi Army Depot (CCAD) in Texas has begun in-house production of replacement tail fins for the UH-60 Black Hawk helicopter's Crashworthy External Fuel System (CEFS) using 3D printing due to shortages from the original equipment manufacturer. Initiated in October 2025, the project responds to the need for reliable parts supply and aims to cut costs and lead times.

The tail fin is frequently damaged, necessitating quick replacements. The depot acquired polyetherimide thermoplastic and software over two months and printed the fin in four segments over 82 hours, with additional inspection time. The project aligns with a broader Army shift towards composite materials to improve maintenance and readiness.
