Phaostron Instrument And Electronic Company

Phaostron Instrument and Electronic Company, doing business as Phaostron Instrument Electronic Co., manufactures precision electronic components and specialized measurement instrumentation for military aviation and defense logistics, operating exclusively as a prime contractor on Defense Department purchase orders, delivery orders, and indefinite delivery contracts. A woman-owned, for-profit Subchapter S corporation based in Azusa, California, Phaostron competes predominantly in full-and-open solicitations without set-aside designation, though it qualifies as a small business and has received multiple total small business set-aside awards from the Defense Logistics Agency.

Phaostron's capability footprint centers on configuration-controlled, source-tracked electronic measurement devices essential to military aviation maintenance and defense equipment readiness. The vendor manufactures pressure transmitters, temperature indicators, pitot tubes, ammeters, voltmeters, tachometers, liquid quantity indicators, pressure indicators, ohmmeters, pressure dial gauges, wattmeters, and related instrumentation. Representative recent work includes a $1.14 million definitive contract from DLA Aviation (March 2026) for a position transmitter unit (NSN 6610-006841341) for the U-2 Airframe under MIL-T-26609C Revision C; a $529,114 purchase order (June 2025) for pressure transmitters under an existing indefinite delivery vehicle; and a $231,162 delivery order (May 2024) for humidity-temperature probes supporting aviation maintenance operations.

Customer concentration is extreme and narrow. Defense Logistics Agency Aviation dominates the footprint at 1,289 awards representing $131.9 million (91% of combined potential value across the top-three customer agencies). DLA Land and Maritime accounts for 856 awards and $10 million; DLA's parent entity (Defense Logistics Agency) adds 322 awards and $9.5 million. The Department of the Air Force and Department of the Army round out the active set with 56 and 50 awards respectively, though the source shows minimal dollar volume. Phaostron has accumulated over 50 prime federal contracts since registering with the System for Award Management in January 2002, with the bulk of work flowing through DLA Aviation's standing inventory and procurement operations.

Phaostron holds five active Indefinite Delivery Contracts with DLA Aviation, collectively valued at over $8.9 million through 2029 and 2030. The largest vehicle is a $5.6 million total small business set-aside single-award contract (awarded July 2025, expiring July 2030) covering transmitters, pressure indicators, temperature indicators, tachometers, ammeters, voltmeters, and related instrumentation. Other active IDCs include a $1.19 million pitot tube contract (December 2024 to December 2029), a $499,290 pressure transmitter contract (December 2024 to December 2029), a $310,840 pressure indicator contract (May 2024 to December 2025), and a $250,000 liquid quantity indicator contract (January 2025 to January 2030). These vehicles enable DLA Aviation to issue task orders and delivery orders without individual competitive solicitations, streamlining acquisition of components critical to military readiness.

Activity has remained stable at 98 to 136 awards per year over the past five years (2022–2026), with 2,823 total awards in the source and a combined potential value of $263.8 million. Eighteen awards (combined potential value $2.4 million) face ultimate completion within the next twenty-four months and therefore represent recompete exposure. Phaostron operates with no identified subcontractors; all work is performed directly at its Azusa, California manufacturing facility, with delivery timelines ranging from 30 to 326 days depending on component complexity and quantity. The vendor's core PSC codes reflect its product portfolio: 1,084 awards under Electrical and Electronic Properties Measuring and Testing Instruments (PSC 6625), 682 under Pressure, Temperature, and Humidity Measuring and Controlling Instruments (PSC 6650), 537 under Engine Instruments (PSC 6665), and 149 under Flight Instruments (PSC 6610). Phaostron's NAICS footprint is dominated by 6395 (Other Measuring and Controlling Device Manufacturing, 639 awards), 3361 (Other Engine Equipment Manufacturing, 450 awards), and 3344 (Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals, 300 awards).
