About A2 Systems Engineering, Inc.

A2 Systems Engineering, Inc., a veteran-owned small business based in El Segundo, California, provides systems engineering, research and development, and program support services to the Department of Defense and civilian agencies as both a prime contractor (53% of recent awards) and a subcontractor (47%). The vendor operates as a for-profit Subchapter S corporation and competes in full-and-open procurements without set-aside designations.

A2 Systems Engineering's customer base concentrates heavily on Department of Defense organizations. The top five customer segments by award count account for 80% of recent awards and include the Air Force Defense Finance and Accounting Service (3 awards), the Air Force Space Command Space and Missile Systems Center (3 awards), the Navy Naval Sea Systems Command (2 awards), the Office of the Secretary of Defense (2 awards, $11.6 million combined potential value), and the Missile Defense Agency (2 awards, $500 combined potential value). By dollar value, the rankings shift: the GSA Federal Acquisition Service anchors the portfolio with $23.6 million in combined potential value from a single award, the Office of the Secretary of Defense contributes $11.6 million across two awards, and the DoD Washington Headquarters Service adds $8.8 million from one award. The vendor serves eight distinct federal agencies overall, with the most recent activity concentrated in missile defense and space systems work.

A2 Systems Engineering holds a position on the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) IDIQ, a multi-billion-dollar, full-and-open, multiple-award indefinite delivery contract issued by the Missile Defense Agency on January 21, 2026, running through December 28, 2035. The initial delivery order under SHIELD, valued at five hundred dollars as a firm fixed-price award, was also issued on that date; the IDIQ carries a $151 billion ceiling and encompasses research and development, prototyping, systems engineering, weapon design, production, test and evaluation, and cybersecurity across multiple classification levels. A2 also places orders against the One Acquisition Solution for Integrated Services (OASIS) and OASIS Small Business vehicles (7 task orders combined), the GSA Multiple Award Schedule (3 task orders, $20.3 million combined potential value), and SeaPort-e (1 task order). The vendor's award portfolio concentrates on research and development in the physical and engineering sciences (8 awards) and engineering services (5 awards), with secondary work in support and administrative categories.

In its subcontractor capacity, A2 Systems Engineering delivers ground systems engineering and integration support to Booz Allen Hamilton on three Space Systems Command (SSC) Ground Systems Engineering and Integration Support (GSIS) task orders issued between February 2024 and March 2025. The vendor also subcontracts to Modern Technology Solutions, Inc. on MUOS system engineering and logistics support services (awarded November 2022). The vendor's GSA Schedule labor portfolio spans twelve categories at hourly rates ranging from $104.90 to $236.77, grounded in systems engineering, program management, and subject-matter expertise roles requiring bachelor's degrees and up to twenty-five years of experience; no security-cleared labor categories are offered. Recent activity shows modest award velocity — two awards in 2021 and 2022, two in 2024, one in 2025, and two in 2026 — with combined obligated dollars reaching $41.4 million against a combined potential value of $44 million across the entire recent portfolio.
