About this IDV

Written by GovTribe AI ·

Leidos, Inc., operating through its Leidos Services Operating Segment (doing business as SAIC), holds a single-award Indefinite Delivery Contract valued at $321.0 million with the Naval Sea Systems Command for services and supplies supporting the operation of the Code 15 Naval Array Technical Support Center (NATSC) facility. The contract, awarded November 6, 2020, with an ultimate completion date of March 30, 2026, encompasses comprehensive depot-level maintenance and technical support for towed array sonar systems serving both the U.S. Navy and Foreign Military Sales customers. Core contract deliverables include manufacturing, upgrading, repairing, refurbishing, diagnosing, troubleshooting, testing, and evaluating towed arrays and component parts, with the contractor required to procure approximately 20,000 individual parts and materials annually to support facility operations. Performance takes place at the Naval Array Technical Support Center facility in Newport, Rhode Island, with secondary operations in Reston, Virginia and Herndon, Virginia. The contract employs a cost-plus-fixed-fee structure for major facility operations delivery orders and firm fixed-price arrangements for discrete material procurement and engineering services. No set-aside designation was applied to this award.

Delivery orders issued under the contract vehicle demonstrate sustained execution across multiple fiscal years, with recent awards totaling approximately $22.3 million for fiscal year 2025 operations and $21.7 million for fiscal year 2024 operations, representing continuation of critical operational support for Naval Sea Systems Command's undersea warfare capabilities. Task orders reflect a diverse procurement portfolio encompassing facility operations and technical support services, specialized sensor and hose components (including towed array acoustic hoses, vibration isolation materials, and pressure instrumentation), electrical connectors and cable assemblies, machined hardware components, and spare parts for array system maintenance. Leidos manages an extensive subcontractor network including specialized suppliers such as The Spiratex Company (thermoplastic extrusions for underwater applications), Diversified Machining, Inc. (precision-machined titanium components), Paroscientific, Inc. (pressure sensors), Woven Electronics LLC (cable assemblies), and multiple smaller component manufacturers. The contract supports Naval Sea Systems Command's mission to maintain operational readiness of the Navy's towed array sonar systems, which represent critical passive acoustic detection platforms essential to submarine detection, underwater surveillance, and anti-submarine warfare operations across the naval fleet.
