Boeing's Seattle operation just landed a fresh Pentagon payday, securing an $854.7 million contract that folds four additional P-8A Poseidon jets into an ongoing foreign military production run while also paying for fleet-wide upgrades. The deal pairs new aircraft production with engineering work to shore up supply-chain weak spots and refresh software and hardware on Poseidons already flying.

According to a contracts notice from the Department of Defense, Naval Air Systems Command issued an $854,672,911 modification to Boeing for production and delivery of four P-8A Lot 13 aircraft for Foreign Military Sale customers. The same notice states that the award includes non-recurring engineering to address diminishing manufacturing sources, material shortages, software integration and hardware updates for both the U.S. Navy and allied buyers.

The P-8A is a militarized version of the Boeing 737 configured for long-range anti-submarine warfare, anti-surface warfare, intelligence, surveillance and reconnaissance, and search-and-rescue. Those capabilities are meant to let partner militaries hunt submarines and maintain maritime awareness over wide ocean areas. Boeing notes that current P-8A operators include the U.S. Navy, the Royal Australian Air Force, the Indian Navy, the U.K. Royal Air Force and Norway's air force.

Trade coverage that mirrored the Pentagon filing put roughly 98.2% of the contract work in the Seattle area, with small portions in Huntington Beach and other continental U.S. locations, and set an expected completion date in September 2030. Investing.com also reports that most of the funding will come from Foreign Military Sales customer funds, with a small portion drawn from prior Navy aircraft procurement money at the time of award.

What the Upgrade Money Buys

The contract modification pays for non-recurring engineering aimed at mitigating diminishing manufacturing sources, material shortages and other supply-chain risks. It also covers mission-system software integration and hardware refresh work that will affect both U.S. Navy and allied P-8A fleets. As reported by AL.com, the effort is designed to keep Lot 13 production moving while modernizing aircraft already in service.

Recent Retrofit Work

Earlier this month, the Navy also moved to bolster anti-submarine capability across the P-8A fleet with retrofit kit installations. That came in the form of a roughly $12 million modification to install an Increment 3 retrofit kit, listed in the Pentagon's April contracts roundup. The Department of Defense indicates those retrofit actions are expected to wrap up in late 2026.

The May award does not specify which foreign governments will receive the four additional Lot 13 jets, leaving open whether the aircraft will fold into previously announced sales. Earlier Lot 13 purchasing included a $3.4 billion procurement for 17 P-8As tied to Canada and Germany, prior work that helps explain why Boeing's Seattle production line remains the center of gravity for Poseidon output, according to Defense Daily.
