Fei-Zyfer, Inc.

Fei-Zyfer, Inc., doing business as FEI Zyfer Inc., manufactures precision time and frequency instrumentation and electronic components as a prime contractor to the Department of Defense and Navy, competing full-and-open (87% of 295 recent awards are prime contracts with no set-aside designation). Fei-Zyfer is a non-small business subsidiary of Frequency Electronics Inc., headquartered in Uniondale, New York, based in Garden Grove, California, and operates in instrument manufacturing (NAICS 334519 and subordinate codes) and electrical and electronic assemblies (PSC 5998).

Fei-Zyfer's capability portfolio centers on GPS time and frequency systems, rubidium and disciplined oscillators, network time servers, circuit card assemblies, and M-Code receivers for military navigation, communications, and timing applications. Recent prime awards include a $3.14 million firm fixed-price delivery order from the Aviation and Missile Command (August 2025) for electronic components supporting the M-D6 PATRIOT missile system; a $4.45 million definitive contract from the Army Materiel Command Aviation and Missile Life Cycle Management Command (November 2023) for 44 units of unspecified electronic components; and a $2 million purchase order from the Naval Observatory (September 2023) for twenty-four upgraded time and frequency reference measurement systems (VHP RB oscillators). Fei-Zyfer also holds a single-award Indefinite Delivery Contract with the Army (issued June 5, 2025, through Defense Logistics Agency Aviation) with a ceiling of $6.66 million through December 31, 2028, for electronic components supporting PATRIOT systems. Recent awards are priced firm fixed-price and awarded on a sole-source basis under FAR 6.302-1(a)(1), citing data rights restrictions that limit government sourcing to Fei-Zyfer.

Customer concentration is heavily Navy-skewed. The top five customers account for 63% of recent awards. The Naval Supply Systems Command (76 awards, $2.8 million combined potential value) and Naval Information Warfare Systems Command (70 awards, $2.9 million) dominate by award count, but by dollar magnitude the Army Materiel Command Aviation and Missile Life Cycle Management Command leads (4 awards, $9.2 million combined potential value), followed by Naval Observatory (17 awards, $6.7 million). Small-value purchase orders to Navy supply command and Naval Information Warfare Systems Command represent high-volume, low-dollar routine component procurement; larger dollar awards flow through Army aviation and missile programs and Navy Observatory modernization efforts. Fei-Zyfer serves 53 distinct federal agencies, though the Navy accounts for the bulk of activity.

Fei-Zyfer places 86 task orders under the Scientific Equipment and Services vehicle with an estimated $5.2 million combined potential value, and holds positions on multiple Basic Ordering Agreements with the Air Force (FA862016G3027 with 6 task orders; FA862021G4027 with 6 task orders). The vendor also executes work under the Indefinite Delivery Contract HQ014718D0002 (4 task orders) and FA852819D0015 (3 task orders). Activity over the past five years shows growth from 2 awards in 2022 to 21 in 2024, declining to 17 in 2025 and 2 year-to-date in 2026. Three awards (combined potential value $4.8 million) complete within the next twenty-four months, representing moderate recompete exposure.

As a subcontractor, Fei-Zyfer supplies GPS receivers, time and frequency systems (GSYNC and CommSync II products), oscillators, and circuit card assemblies to major primes including Raytheon (multiple sub-awards for AN/TPY-2 radar development and production GPS receivers), L3Harris Technologies (aircraft manufacturing and M-Code capability integration), Lockheed Martin (U-2 avionics technology refresh and THAAD systems), Leidos (GSM-O II integration support and maintenance), and SAIC (Air Operations Center Falconer service). Sub work spans defense electronics integration, aircraft avionics modernization, and precision timing systems for ground and airborne platforms. Across both prime and subcontractor roles, Fei-Zyfer's federal footprint is concentrated in military precision timing, navigation-grade GPS, and specialized electronic assemblies, with no civilian agency customer presence.
