Curtiss-Wright Flow Control Service, LLC

Curtiss-Wright Flow Control Service, LLC, doing business as Engineered Arresting Systems - Esco, manufactures aircraft arresting systems, components, and related maintenance services for the Department of Defense as a prime contractor, with no meaningful subcontract footprint. The company is a wholly owned subsidiary of Curtiss-Wright Corporation (parent: Parsippany, New Jersey) and operates from Marcus Hook, Pennsylvania, with all performance at Upper Chichester, Pennsylvania. Curtiss-Wright Flow Control Service competes exclusively on full-and-open, unrestricted basis — no set-aside designations appear across the award footprint.

The vendor's customer concentration is extreme and heavily weighted toward logistics and sustainment vehicles. Defense Logistics Agency Land and Maritime dominates award count at 810 awards ($35.6 million combined potential value), followed by Naval Air Systems Command Naval Air Warfare Center with 118 awards ($96.1 million) and Defense Logistics Agency Aviation with 157 awards ($3.8 million). This top five covers 78 percent of awards. By potential value, however, Air Force Materiel Command Lifecycle Management Center at Robins Air Force Base anchors the portfolio at 60 awards and $128 million combined potential value — a stark concentration signal. The vendor's dollar base is therefore anchored in Air Force and Navy aircraft arresting system sustainment, not in the high-volume, low-dollar DLA Land and Maritime commodity business that drives award count.

Capability is tightly specialized. Curtiss-Wright's award portfolio reflects three narrowly focused product and service lines: E28 retrieve drive assemblies for naval aircraft carrier arrestors; Mobile Runway Edge Sheaves (MRES) for ground-based Mobile Aircraft Arresting Systems (MAAS); and textile aircraft braking systems, webbing assemblies, brake drums, and related component kits. Concrete recent examples include a $31.4 million firm fixed-price delivery order from Air Force Life Cycle Management Center (September 2025) for MRES acquisition and sustainment; a $6.9 million delivery order from Office of Naval Research (July 2024) for E28 retrieve drive assemblies; a $1.5 million purchase order from Air Forces Europe and Africa (September 2024) for 435 MAAS trailers; and recurring Defense Logistics Agency Land and Maritime orders for reconditioning kits and components at values between $130 thousand and $660 thousand. The vendor also performs depot-level overhaul, contractor logistics support, and advanced troubleshooting training for naval arresting systems.

Vehicle position is built on two large single-award indefinite delivery contracts. A $28.4 million IDC with Naval Air Warfare Center (awarded March 2023, completion March 2028) funds E28 retrieve drive assemblies with four delivery orders issued totaling $13.7 million as of August 2025. A $20.6 million IDC with Naval Air Warfare Center (awarded March 2022, completion March 2027) funds depot-level overhauls, logistics support, and advanced troubleshooting training with multiple delivery orders ranging from $2,938 to $1.55 million. Five additional parent vehicles named in the source include Air Force, Defense Logistics Agency, and Navy IDCs and Basic Ordering Agreements in the $3.7 million to $11.2 million range per vehicle. The top five vehicles carry 120 combined task orders and $41.5 million in combined potential value.

Activity has been steady but not growth-oriented. Awards per year show 2022 (17), 2023 (29), 2024 (29), 2025 (19), and 2026 (1 award to date). The vendor faces a recompete cliff of nine awards with combined potential value $47.7 million due to completion within the next twenty-four months — a material exposure for a vendor with $344 million in total portfolio potential value.

Category concentration by NAICS and PSC confirms the specialization. Of 1,605 total awards, 573 are classified under NAICS 336413 (Other Aircraft Parts and Auxiliary Equipment Manufacturing), and 659 fall under PSC Aircraft Landing Equipment. Mechanical power transmission, hardware manufacturing, and gear manufacturing round out the secondary NAICS codes, but the portfolio is fundamentally a single-product, single-customer-set business: aircraft arresting system components and sustainment for the Navy, Air Force, and Defense Logistics Agency supply chain.

The vendor holds no federal grant awards and no subcontract presence of note. Three sub-award records show General Atomics as prime on unrelated work (inertial confinement fusion research, 2024–2025), suggesting incidental or historical engagement rather than active sub strategy.
