NAVSUP Weapon Systems Support Philadelphia intends to issue a sole-source procurement to Sikorsky for one specific aircraft window unit. The government states it lacks the data rights to purchase this part from other sources and anticipates only one acceptable offer. Proposals received within 45 days of the synopsis will be considered, potentially to determine if a future competitive procurement is viable. The award is expected to be issued under an existing Basic Ordering Agreement. Interested parties may submit their capabilities via a specified email address.
