Hamble Aerostructures LIMITED

Hamble Aerostructures LIMITED, a foreign-owned aircraft components manufacturer based in Southampton, United Kingdom, supplies specialized wing pylon assemblies and related aerostructures to the U.S. Navy as a prime contractor, competing in full-and-open procurements without set-aside designation. The vendor operates as a manufacturer of goods under primary NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing) and has established itself as a sole supplier of P-8A Poseidon wing pylon assemblies to Naval Air Systems Command (NAVAIR) since 2019.

NAVAIR dominates the vendor's customer concentration entirely—five awards totaling $123.9 million in combined potential value represent 100% of significant federal exposure, with the remaining two awards (Defense Logistics Agency Aviation and Naval Supply Systems Command) adding $511 thousand combined. The vendor holds an indefinite delivery contract with NAVAIR (N0001920D0012) established in 2020 and carrying a potential value exceeding $40 million; the two most recent awards—a $14.96 million definitive contract awarded January 26, 2026, for Lot 13 P-8A wing pylon assemblies designated for Canada and Germany, running through December 31, 2029, and an earlier $12.46 million delivery order from November 9, 2021, for Lot 12 aircraft production—are task orders placed under this vehicle. Prior NAVAIR awards dating to 2019 have cumulatively exceeded $39 million in P-8A component procurement.

The vendor's award activity remains episodic—one award per year in 2025 and 2026 after a gap from 2022 through 2024—reflecting the lumpy nature of international military sales production planning for a single platform. Combined obligated dollars across all seven awards reach $102.2 million (82% of the $124.4 million potential value ceiling). Hamble Aerostructures subcontracts to The Boeing Company on a $511 thousand wing pylon aerospace-support task awarded May 22, 2025, indicating a secondary sub role on broader P-8A sustainment work. The vendor's capability footprint is narrowly focused: P-8A structural wing pylon manufacturing and associated component production for a single major defense acquisition program, with no diversification into other platforms or customer agencies visible in recent awards.
