• Base of Operations: No preferred location, but must meet RFP-specified distance requirements. Remote Split Operations (RSO) are not compliant with the daily transportation requirement.
• Flight Pattern/Altitude: Sonobuoys launched no lower than 500 feet AGL; patterns are typically tight racetrack within the operating area.
• Aircraft Tracking: Via standard radars, IFF, and ADS-B/Out.
• Ownership/Possession: Proof of ownership or lease agreement for at least one proposed aircraft (T/M/S) is required at time of award.

• Remotely Piloted Systems: Contractor proposals will be evaluated per Sections L & M of the final RFP.
• Current Aircraft: P-3C is currently completing the mission.
• SLAT Event Origin: SLAT events will originate from the contractor's base of operations.

These clarifications provide essential details on performance periods, contract type, operational requirements, equipment, and submission criteria, directly impacting how offerors should prepare their proposals and understand the scope of work.

Statement of Work (SOW) / Performance Work Statement (PWS)

This Performance Work Statement (PWS) outlines the requirements for Contractor Owned Contractor Operated (COCO) aircraft services to support the Naval Air Systems Command (NAVAIR) Program Manager, Adversary and Specialized Aircraft (PMA-226) program. The primary goal is to provide aerial deployment of production and pre-production sonobuoys for Sonobuoy Lot Acceptance Testing (SLAT) to ensure compliance with performance and reliability specifications before fleet delivery.

• Provide FAA certificated aircraft and personnel capable of supporting SLAT missions.

• Aircraft must be equipped with a pneumatic launch system for NATO 'A' size sonobuoys.

• Missions involve overwater flight profiles up to 100 NM offshore, at altitudes from 500 to 8,000 feet Mean Sea Level (MSL), with stable airspeeds below 250 KIAS.

• Each mission requires a single flight sortie, deploying 32 to 52 sonobuoys.

• Operations will primarily occur over open-ocean test ranges near San Clemente Island, CA, coordinated with a Government-operated surface vessel.

• Support includes Sonobuoy Lot Acceptance Testing, Engineering Test Drops, Pattern Accuracy Testing, Mammal Mitigation & Range Clearance, and Training/Rehearsal Sorties.
