About this IDV

Written by GovTribe AI ·

Syqwest LLC, a Rhode Island-based manufacturer of advanced naval electronic components and acoustic systems, was awarded a single-award Indefinite Delivery Contract by the Naval Sea Systems Command (NAVSEA) on April 26, 2021, with a ceiling value of $10,090,125 and an ultimate completion date of April 25, 2026. The contract encompasses the design, manufacture, and delivery of DT-513 Series hydrophones, including multiple variants (DT-513D, DT-513F, DT-513H), which are critical underwater acoustic detection systems essential to submarine, shipbuilding, and undersea warfare capabilities. This indefinite delivery vehicle is not set aside and enables NAVSEA to procure these mission-critical naval electronic components on an as-needed basis through firm-fixed-price delivery orders, with work performed at Syqwest facilities located in Cranston and Newport, Rhode Island, and Woburn, Massachusetts.

Under this IDC, NAVSEA has issued ten delivery orders totaling approximately $5.6 million since the contract's inception, with the most recent orders awarded in 2025 for DT-513F hydrophone equipment valued at $887,900 and $830,300 to support Code 15S mission-critical efforts aimed at enhancing fleet readiness. Earlier delivery orders, spanning from May 2021 through October 2024, procured various hydrophone configurations including block buy arrangements for DT-513D models and production orders for DT-513F variants. The contract represents a strategic supply relationship supporting the Navy's underwater acoustic detection and submarine communication infrastructure, with delivery orders extending performance periods through 2030 to ensure continuous availability of these specialized components for fleet maintenance and operational readiness.
