SI2 Technologies, Inc.

SI2 Technologies, Inc., a North Billerica, Massachusetts–based small business, is a subsidiary of Antenna Research Associates, Incorporated and serves as a prime contractor on advanced communications, sensing, and radar technology programs across the Department of Defense, with 94% of recent awards as prime (155 of 165 total awards) and no set-aside posture — the company competes under full-and-open solicitations despite small-business eligibility.

SI2 Technologies' capability footprint centers on defense RF systems, antenna design, radar-absorbing materials, electronic component development, and ground-based surveillance equipment, grounded in sustained Small Business Innovation Research (SBIR) participation. Recent work spans Global Broadcast Service (GBS) equipment procurement and sustainment under a single-award $80 million SBIR Phase III contract with the Space and Missile Systems Center (extended through August 22, 2030), including a $1.542 million delivery order for ten units of GBS equipment (September 29, 2025), a $2.7 million Department of Navy delivery order for GBS services (July 7, 2025), and a $2.34 million Marine Corps order for GBS Portable Receive Suite systems (June 9, 2025). The company also delivers sensor and RF technology research under Air Force Research Laboratory SBIR Phase II awards, including a $13.16 million total-small-business-set-aside definitive contract for low-cost sensors for small unmanned vehicles (May 30, 2025, performance in Santa Barbara, California) and a $1.8 million Phase II contract for wideband front-end electronics supporting multi-function seekers (October 25, 2024). Sub-award activity includes electronic sensing R&D labor for BAE Systems Information and Electronic Systems Integration on the Sound Garden program (six awards dating June 2025 through March 2026) and an electronic prototype order from Bowhead Program Management & Operations (October 8, 2024).

Customer concentration is heavily weighted to Air Force and missile-defense programs. The top five funding agencies account for 62% of award count: the Department of the Air Force Materiel Command Research Laboratory leads with 36 awards ($73.4 million combined potential value), followed by the Department of the Army Research Development and Engineering Command (28 awards, $25.2 million), the Department of the Navy Naval Air Systems Command Naval Air Warfare Center (15 awards, $8.1 million), the Missile Defense Agency (13 awards, $6.8 million), and the Air Force Space and Missile Systems Center (11 awards, $130.2 million). By dollar value, concentration is extreme: the Eglin Wide Agile Acquisition Contract (EWAAC) vehicle anchors $46 billion in potential value across two awards, followed by the Office of Naval Research at $900.7 million (six awards), Space and Missile Systems Center at $130.2 million, the Air Force Research Laboratory at $73.4 million, and the Army at $25.2 million.

SI2 Technologies holds three primary vehicle positions. The $80 million SBIR Phase III single-award contract with Space and Missile Systems Center for GBS products, program management, and technical support has generated delivery orders spanning GBS equipment procurement, closeouts, and spare-parts support across multiple military branches (Marine Corps, Navy, Air Force). The $46 billion Eglin Wide Agile Acquisition Contract (EWAAC), a multiple-award IDIQ with the Air Force Materiel Command Lifecycle Management Center awarded March 14, 2023 (ultimate completion September 9, 2031), provides a broad procurement vehicle for RF systems, antenna technologies including conformal peel-and-stick antennas for unmanned aircraft, frequency selective surfaces, radar-absorbing materials, and wideband multifunction RF sensing; one documented delivery order of $1,000 for EWAAC Program Acquisition Cybersecurity requirements was issued April 3, 2023. SI2 Technologies was also awarded a seat on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) multiple-award IDIQ (Missile Defense Agency, awarded December 29, 2025, $151 billion ceiling, completion December 28, 2035) with a $500 initial delivery order issued concurrently. A Basic Ordering Agreement with the Naval Air Warfare Center (awarded March 9, 2022, completion March 8, 2027) rounds out the IDV portfolio.

Activity growth has been uneven but recently elevated. Awards-per-year totals from 2022–2026 show: five in 2022, eleven in 2023, nine in 2024, fifteen in 2025, and five in 2026 (through April 1). Five awards with ultimate completion dates within the next twenty-four months carry combined potential value of $43.3 million and face recompete. The company's award portfolio totals 165 awards (155 prime, ten sub) with $47.19 billion combined potential value but only $145.1 million in actual dollars obligated — the extreme discrepancy reflects the multi-billion-dollar ceiling values of the Eglin and SHIELD contracts, which are rarely drawn upon in their entirety. SBIR work dominates the category concentration: 70 awards under "Research and Development in the Physical, Engineering, and Life Sciences (except Biotechnology)" NAICS and 26 awards under "R&D- Defense Other" (Applied Research/Exploratory Development) PSC codes, with sustained Army, Air Force Research Laboratory, and Navy engagement across Phase I, Phase II, and Phase III SBIR vehicles.

SI2 Technologies is dedicated to the design and manufacture of electromagnetic systems for military and government platforms constrained for space, weight and power. Specifically, SI2's design and manufacturing efforts focus on antennas, arrays and signal management products for military air, land, sea and space applications.
