About
SI Defense
SI Defense was conceived by an aerospace manufacturer, which is owned by a Service Disabled Vietnam Veteran located in beautiful Kalispell Montana.
The owner, Richard Sonju, fought for the United States of America in the Vietnam War, where he gathered military intelligence in coordination with the Special Forces on the turbulent borders of Cambodia and Laos.
His first hand experience in the field, along with his history in aerospace manufacturing brings a whole new meaning to reliability and quality in the defense business.
SI Defense employs many veterans and individuals who are passionate about what they do. When a company and its employees are passionate about something, it shows in the products that are offered to its customers. SI Defense uses some of the most sophisticated equipment in the world to build its components, but we still use good old fashion customer service to take orders and answer questions.
SI Defense guarantees the products we offer, and we love to hear from our customers. We want to know how to improve our products; we want to hear your success stories. Our number one priority is to have you as our customer for life!
