The Department of Defense, specifically the Department of the Navy through NAVSUP Weapon Systems Support, is seeking to procure a Slack Elevator Switch, identified by NSN 1H-9999-LLCYC3987, under a presolicitation notice. The procurement involves a quantity of one unit, which is to be delivered to the USS Makin Island (LHD 8), and is set aside for total small business participation in accordance with FAR 19.5. This item is critical for operational readiness and maintenance of naval vessels, and the government has determined that it is uneconomical to purchase the data or rights needed for alternative sources. Interested parties should contact Olivia Snyder at (717) 605-4614 or via email at OLIVIA.SNYDER2@NAVY.MIL for further details, with proposals due within 45 days of the notice publication.
