First Increment 3 Block 2 modifications complete for P-8A Poseidon aircraft 

From Naval Air Systems Command, June 13, 2025 

PATUXENT RIVER, Md. — Increment 3 Block 2 modifications are complete for the first P-8A Poseidon aircraft. The modifications outfit the P-8A with the full anti-submarine warfare (ASW), anti-surface warfare (ASuW), and intelligence, surveillance and reconnaissance (ISR) capabilities outlined in the P-8A program’s evolutionary acquisition strategy. The modifications began at Boeing’s Maintenance, Repair and Overhaul hangar at Cecil Airport in Jacksonville, Florida in March 2024. 

“In today’s ever changing global environment, it is important to pace the threat in terms of lethality and survivability.  The Increment 3 Block 2 modifications to the P-8A Poseidon will ensure they remain the most sophisticated and capable maritime patrol and reconnaissance aircraft in the world,” said Capt. Erik Thomas, Maritime Patrol and Reconnaissance Aircraft Program Office (PMA-290) program manager.  

The P-8A is the Department of Defense’s only long-range full-spectrum ASW, cue-to-kill platform, with substantial armed ASuW and networked ISR capabilities.  Increment 3 Block 2 provides a significant upgrade to the P-8A airframe and avionics systems, and includes new airframe racks, radome, antennas, sensors, and wiring. The modification incorporates a new combat systems suite with improved computer processing, higher security architecture, a wide band satellite communication system, an ASW signals intelligence capability, a track management system, and additional communications and acoustics systems to enhance search, detection and targeting capabilities. 

In response to evolving threats around the world, future P-8A modifications will be made via a sequence of rapid capability insertion efforts that build upon this new Increment 3 Block 2 baseline.
