The Department of Defense, through the Naval Air Warfare Center Aircraft Division (NAWC-AD), intends to award a task order to Dayton T. Brown, Inc. for sustainment services related to the E-2D Mobile Mission System (MMS). The task order will encompass planned maintenance, unplanned troubleshooting, and operational deployment support, and will be issued under Basic Ordering Agreement N0042123G0005, utilizing a combination of firm fixed price and cost-plus fixed fee contract types. This procurement is being conducted on a sole source basis, as the government asserts that only one capable provider exists for these specialized services. Interested parties can direct inquiries to Cylinda Middleton or Lydia F. Munley via their respective email addresses for further information.
