About Us

Where Technology Meets Tomorrow

Based in Bühl, Germany, TAG (formerly GMT Aerospace), is a leading provider of highly engineered tie-rods and rubber-metal anti-vibration systems for commercial and military aerospace applications.

Established in 2006, TAG serves most major aircraft manufacturers as a Tier 1 supplier and strategic partner, and supports others through their Tier 1 supply chains.

Engineering For Tomorrow

In its relatively short history, TAG has introduced new standards and technologies to the tie-rod market, continually advancing functional and structural performance in aerospace applications.

By providing direct engineering access and close collaboration throughout development and specification processes, TAG has built a reputation as a true solution provider — capable of managing complex technical challenges and bringing those solutions through validation and into serial production.

Since joining the PennAero Aerospace family in early 2025, TAG has further strengthened its capabilities. As part of a larger aerospace platform, the company can now vertically integrate more effectively within customer supply chains — accelerating value-added programs and scaling volume production faster than ever before.

Unrivaled Quality and Performance

TAG’s performance speaks for itself: a proven 97% on-time delivery (OTD) rate across all customers and 100% OTD to major OEMs sustained over multiple years.

Repeated supplier awards reflect TAG’s commitment to partnership — not only with customers, but across the supply chain. Strong communication, responsiveness, and collaboration enable TAG to address challenges quickly and effectively. This dedicated customer focus, paired with high agility and technical depth, is highly valued across its global customer base.

Despite its growth, TAG has retained its entrepreneurial spirit, making it the industry’s go-to partner for solving complex and specialized challenges. The company delivers out-of-the-box thinking and design-to-build solutions, and holds the unique capability to produce rubber-based linear damping rods, while simultaneously supporting higher-volume production of standard product lines.

Key Customers

TAG partners with leading aerospace OEMs, Tier 1 suppliers, and MRO providers across commercial and military programs, delivering highly engineered tie-rod and anti-vibration solutions that enhance structural integrity, mitigate vibration, and improve system reliability.

Since joining PennAero Aerospace in 2025, TAG has further strengthened its European presence and expanded support for key fixed- and rotary-wing platforms, aligning with the broader PennAero Aerospace heritage — including major Airbus programs and critical defense applications.
