Garmin Delivers 1,000th King Air G1000 Retrofit, to U.S. Army C-12 Fleet
Why It MattersA thousand retrofits over roughly nineteen years shows avionics replacement on legacy turboprops has become a mature, repeatable upgrade market that military fleet programs can use to extend airframe service lives.
What happened
Garmin (NYSE: GRMN) announced on Oct. 13, 2026 the delivery of its 1,000th G1000 integrated flight deck retrofit for King Air aircraft. The 1,000th retrofit went to the U.S. Army during an Oct. 6 celebration at Stevens Aerospace and Defense.
The U.S. Army has upgraded more than 40 C-12 Huron aircraft with G1000 NXi so far, standardizing the fleet on modern, integrated avionics. The Army began the avionics modernization to maintain C-12 mission readiness through 2050, selected the G1000 NXi as the fleet's next-generation avionics, and awarded the upgrade contract to Stevens Aerospace.
Garmin received the first supplemental type certificate (STC) for a King Air G1000 retrofit in November 2007, followed by certification of G1000 NXi in January 2017. The program now covers multiple King Air variants, including the C90A/B, 200, B200, 300 and 350 series and C-12 variants, with foreign certification validations supporting upgrades worldwide.
The retrofit replaces legacy avionics with a fully integrated flight deck with large-screen displays. Garmin has more recently added Autothrottle and Autoland for eligible King Air aircraft.

Industry impact & what to watch
Retrofitting avionics instead of replacing airframes is how long-lived turboprop fleets stay current. A program that has produced a thousand installations since the first certificate in 2007 shows that the work has moved from one-off projects to a standard offering across several King Air variants, with foreign validations extending it beyond the U.S. market.
The Army's choice matters beyond its own fleet. A modernization aimed at keeping C-12 aircraft mission-ready through 2050 treats the airframe as a multi-decade asset and the cockpit as the part that gets renewed. Defense programs of this kind tend to give installers and avionics suppliers steady, predictable work, which in turn supports the aftermarket for civil operators using the same hardware.
The next milestone to follow is how many of the Army's C-12 aircraft complete the upgrade beyond the more than 40 done so far, and how many eligible King Air operators add Autothrottle and Autoland to their retrofits.
