They may experience decreased reliability, increased sustainment costs, obsolete technology, and a life cycle payback that is more than the remaining life of the system. Derco, a Sikorsky Aerospace Services company, listens to and understands our customer's needs by offering Performance Based Logistics (PBL) solutions that provide greater operational efficiency for defense systems, reduce life cycle costs, and improve parts availability- all within a simplified supply chain.
