 F-5 30G Indicator

The Kellstrom Defense 30G indicator fills a void for international F-5 operators and is a cost effective solution aiding in sustainment of the F-5 fleet. KD created its own technical design for the 30G indicators based on samples provided by one of its customers. The engineering team modeled all of the components using CAD modeling software and created its own test plan to qualify the units based on intelligence gathered from the end users. To date, KD has supplied 50+ indicators to the international military market with no reported defects.
