S3 International was founded in 2005 with the intent to provide innovative, cost effective spare and repair solutions to the civil and military aviation aftermarket. The company grew at an accelerated rate and evolved into a dependable and recognized solutions provider to the military Maintenance, Repair, & Overhaul (MRO) sector. S3 International began to provide more complex logistic and component repair programs for aircraft maintenance and flight operations around the globe.
By 2011, S3 International had formed S3 Repair Services, LLC, (S3R) wholly owned and operated by S3. Shortly thereafter, S3 Repair achieved the FAA and EASA certifications.
Two years later, S3 moved into a 25,000 square foot facility that allowed for both S3 International and S3 Repair Services to be under one roof in Milwaukee, Wisconsin.
In 2015, S3 established another repair station, S3 Brasil - Serviços de Manutenção Aeronáutica Ltda., a wholly owned subsidiary of S3 International, located in Brazil. By increasing our global presence, S3 Brasil now expands our cost effective solutions to the South American market and allows us to further expand our exports.
