D & R began operations in 1990 as a 100% dedicated military / defense supplier, performing Product Support Analyses (PSA) in support of various military programs. Since that time, we have continued to support our military customers across a wide range of DoD programs, end customers, and equipment types. Our involvement begins at initial proposal activity for supportability related activity and CDRLs, including manuals, training, RCM, LORA, spares provisioning and more. Our involvement extends through the project life cycle, from development and test through production and fielding. Supportability activity includes initial Support Plans, Guidance Conferences, Supportability IPTs, Spares Conferences, Validations and Verifications, and NET and IKPT training events.

The market we serve for military projects ranges from small and mid-sized equipment suppliers without the staff and resources necessary to properly address the supportability requirements, to larger companies needing some specialized support (RCM, Provisioning, etc.).
