The Preliminary Operational Functionality (IOC) was achieved after testing carried out by Air Take a look at and Analysis Squadron One (VX-1) with help from the Maritime Patrol and Reconnaissance Plane Program Workplace (PMA-290).
The U.S. Navy has declared Preliminary Operational Functionality (IOC) for the P-8A Poseidon Increment 3 Block 2 (Inc 3 Blk 2) system.
“The P-8A Inc 3 Blk 2 modifications improve Naval Aviation’s Maritime Intelligence, Surveillance, Reconnaissance, and Concentrating on (ISR&T) capabilities – the eyes of the Fleet,” stated Rear Adm. Michael Wosje, Director of Air Warfare (OPNAV N98) in a public assertion. “This functionality enhancement is in step with the CNO Preventing Directions and the Golden Fleet Initiative, which shifts the paradigm from platform-centric considering to a warfighting system. We’re delivering the P-8A Inc 3 Blk 2 as a high-end, networked, and quickly adaptable platform.”
As we reported in June 2025, when the primary P-8A Increment 3 Block 2, delivered to the U.S. Navy the identical month, flew for the primary time, the improve consists of new airframe racks, radome, antennas, sensors, and wiring. The electronics comprise “a brand new fight methods suite with improved laptop processing, larger safety structure, a large band satellite tv for pc communication system, an ASW alerts intelligence functionality, a monitor administration system, and extra communications and acoustics methods to reinforce search, detection and focusing on capabilities. It brings the complete ASW, anti-surface warfare (ASuW), and intelligence, surveillance and reconnaissance (ISR) capabilities outlined within the P-8A program’s evolutionary acquisition technique.”
The modified P-8A BuNo 169562 is without doubt one of the seven airframes chosen for the upgrades within the contract with Boeing. Increment 3 Block 2 associated modifications had been applied at Boeing’s Upkeep, Restore and Overhaul hangar at Cecil Airport in Jacksonville, Florida.
The P-8, is the Division of Struggle’s solely long-range full-spectrum anti-submarine warfare (ASW), cue-to-kill platform, with substantial armed anti-surface warfare (ASuW) and networked intelligence, surveillance, and reconnaissance (ISR) capabilities.
“The latest deployment of P-8A Increment 3 Block 2 marks the end result of a spiral improvement technique that delivers successful functionality to the Fleet and ensures that the P-8A will stay agile, related, and deadly for many years to come back,” stated Rear Adm. Craig Mattingly, Commander Patrol and Reconnaissance Group (CPRG), liable for the manning, coaching, and equipping of the Maritime Patrol and Reconnaissance fleet of plane for the U.S. Navy.
Among the many new capabilities launched by I3B2, a brand new safe communications suite and an enhanced sonar system that tracks detonation sounds mirrored off submarines and detected by receiver buoys. The improve additionally features a new monitor administration system in the meantime fuses and prioritizes information on a single, aided by higher “computing energy” to fulfill the brand new calls for of the improved mission suite. The plane will even obtain a alerts intelligence (SIGINT) functionality, in addition to the payloads at present utilized by the MQ-4C Triton.
As reported by The Aviationist in Aug. 2024, when a brand new Multi-Mission Pod (MMP) developed by Boeing was noticed on a Navy P-8A Poseidon, I3B2 permits the “aircrews to go looking, find and monitor probably the most superior submarines on the earth, enabling the fleet to tempo the risk with the required functionality and capability to win the struggle.”
For floor strike missions, the P-8A Poseidon can already carry 4 AGM-84 Harpoons beneath its 4 underwing hardpoints, and can be being examined to be built-in with the AGM-184C LRASM (Lengthy-Vary Anti-Ship Missile) by Boeing and the U.S. Navy, with the corporate saying the work was scheduled to be concluded by the summer season of 2024.
PMA-290 has superior P-8A’s capabilities by a phased, incremental acquisition technique utilizing Engineering Change Proposals (ECPs). This strategy started with Increment 1, which reconstituted the capabilities of the legacy P-3C Orion, and continued with additional upgrades in Increment 2.
“I’m extraordinarily pleased with the devoted and centered acquisition staff that’s delivering this functionality to the fleet,” stated Capt. Erik Thomas, PMA-290 program supervisor. “The P-8A Increment 3 Block 2 modifications couldn’t have come at a greater time in our present state of evolving threats. The Poseidon is the cornerstone of refined and deadly world maritime patrol and reconnaissance forces, and this enhanced functionality ensures we maintain the core pillar of world-class maritime intelligence, surveillance, reconnaissance and focusing on (ISR&T) and stay prepared for our present and future fights.”
The Navy has not publicly acknowledged that Increment 3 Block 2 modifies the AN/APS-154 Superior Airborne Sensor (AAS). Nevertheless, the improve’s new fight methods suite, improved processing, monitor administration, larger safety structure and wideband communications are probably to enhance how AAS-derived information could be processed, fused with different onboard sensors, exhibited to the crew and shared throughout the broader kill chain.
The AAS is a Raytheon-developed, podded AESA radar carried in a particular canoe-shaped fairing beneath the P-8A’s fuselage. A successor to the AN/APS-149 Littoral Surveillance Radar System beforehand used on modified P-3C Orions, the AAS considerably expands the Poseidon’s ISR function past conventional maritime patrol missions, offering superior surveillance capabilities believed to incorporate SAR imaging, shifting goal indication over land and at sea, and different labeled intelligence-gathering capabilities. By feeding this information into the P-8A’s mission methods, the sensor helps wide-area maritime and littoral surveillance, land-target monitoring, anti-surface warfare and networked focusing on throughout joint and allied forces.
