Supplier Registration

Register through our Application service to submit your application:

Registration is mandatory to begin interacting with LGS and the Divisions and make your personal data available on Leonardo procurement systems.

After you are done filling out your application form, we will send you your credentials and you will be asked to complete specific questionnaires based on the product categories you selected. For help in determining the most appropriate product category, select this  link and visualize the complete LGS product category list.

 Instructions are available on how to use this service.

You can also contact our helpdesk for support by email at or by calling 800 591122 toll free from inside Italy or +390654641514 if calling from abroad. This service is open Monday through Friday from 9AM to 6PM.

Please note the following:


  • your application does not automatically entail business relations with Leonardo, it is just a way to become a potential supplier
  • specific product category questionnaires must be completed in full if you'd like to be included in the potential category supplier list
  • applications for non-priority product categories will be considered only in case of actual necessity, based on the number of suppliers already in the Register or specific business needs
