The Naval Air Warfare Center in Lakehurst, New Jersey intends to award a sole-source Fixed Price contract to SEAL DYNAMICS LLC for three Engine Air Particle Protection Systems (EAPPS) Test Sets, with options for up to four additional units to support both domestic and FMS CH-53K programs. This procurement is justified under FAR 6.302-1 because the test sets are unique to the CH-53K helicopter and the government lacks data or drawing rights for competition. The manufacturer, Donaldson Company Inc., is the only source for this item, as no authorized distributors exist. No specific budget amounts or submission timelines are mentioned in the notice. Performance of services will be at the contractor's location in Hauppauge, New York.
