"Logistics support is an increasingly large part of our business, our activities range from traditional spares, repairs and training up to a complete logistic solution including operating and maintaining systems on behalf of our customers" said Selex Galileo Chief Executive Officer Fabrizio Giulianini.
"This evolution has seen the introduction of new and innovative contracting models, such as contracting for availability and pay by the hour. These new models allow the company and end-user to share greater responsibility for a system's availability.
"We have moved towards an approach where the market, particularly export customers, appreciate the flexible, modular and accessible nature of this relationship," he said.
SELEX Galileo said it will draw upon its technological and systems integration expertise to provide operational support and will also use third-party products.
"This support can be provided over the whole life cycle of the system, simplifying the supply chain for customers and generating improvements in terms of costs and operational efficiency," it said.
