Five Executives in Aftermarket Service GovCon

Companies like Boeing and Oshkosh Defense engineer some of the most complex industrial and military products that the federal government invests in. Aftermarket service providers play an important role in the government contracting sector as their work can impact national security and mission-critical operations.

Thomasnet, a supplier discovery platform provider, expects the nature of aftermarket services to change along with the growing popularity of new business models, including “as-a-service” deals. The coronavirus pandemic also drove public expectations for touchless processes and augmented reality features.

The Potomac Officers Club — a division of Executive Mosaic — features five executives in government contracting companies providing aftermarket services.
