As part of the Navy’s equipment maintenance and performing testing, Naval Base Kitsap will be conducting late-night and low-level air operations Tuesday and Friday at the Puget Sound Naval Shipyard & Intermediate Maintenance Facility.

According to an NBK press release, nearby residents should expect to hear the flights beginning as late as 10 p.m. until daybreak around 3 a.m., weather permitting. Flights will be conducted by a Fairchild Merlin III aircraft and will include passing over the shipyard between 1,000 and 10,000 feet.

Air operations are subject to change due to mission demands.
