Stellar Solutions Inc.

Stellar Solutions Inc., a woman-owned for-profit Subchapter S corporation headquartered in Los Alamos, California, operates as both a prime contractor (44% of recent awards) and subcontractor (56%) delivering systems engineering, integration, test, and analytical services to space and aerospace programs across NASA, the Department of Defense, and the Missile Defense Agency. The vendor competes full-and-open across its prime footprint with no set-aside designations; recent prime awards include a $151 billion ceiling IDIQ for the Missile Defense Agency's Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) program awarded December 29, 2025, and a $49.1 million delivery order from NASA Ames Research Center on June 9, 2023, for systems engineering supporting the Space Modernization Initiative under the GSA Multiple Award Schedule.

Stellar's customer concentration is heavily weighted toward NASA and Air Force Space Command. The top five customer entities account for 94% of combined potential value, anchored by NASA Ames Research Center ($85.1 million across 4 awards), NASA Headquarters ($71.7 million across 13 awards), and the GSA Federal Acquisition Service ($40.1 million across 3 awards). The Air Force Space and Missile Systems Center (24 awards, $81 thousand combined potential value) and Air Force broadly (21 awards, $700 thousand) dominate the award-count ranking but carry significantly lower dollar values than NASA and GSA customers, indicating numerous smaller task orders relative to award volume. Stellar has worked with 18 distinct federal agencies and customer commands across the source data.

The vendor holds seats on three government-wide vehicles: OASIS+ Unrestricted (no dollar ceiling specified in the source, multiple awards across federal agencies), the GSA Multiple Award Schedule (18 task orders, $129.9 million combined potential value), and the GSA Professional Services Schedule (28 task orders, $93.7 million combined potential value). OASIS+ Unrestricted awards 29 task orders in the source, making it Stellar's largest single-vehicle platform by order count. Alliant II carries 3 task orders. The SHIELD IDIQ, awarded in December 2025, permits both classified and unclassified task orders across multiple North American Industry Classification System codes, with initial performance expected at Huntsville, Alabama, and other locations as specified in individual delivery orders.

Stellar's award portfolio spans engineering services (43 awards) and research and development in physical, engineering, and life sciences (37 awards), with some exposure to guided missile and space vehicle manufacturing (3 awards) and computer systems design services (3 awards). Recent supporting services include a $700 thousand Air Force definitive contract on February 6, 2023, for a 90-day engineering study on the Tranche 2 Ground, Management, and Integration Layer for the Space Development Agency's National Defense Space Architecture. Activity has fluctuated across the past five years—17 awards in 2021, 8 in 2023, 18 in 2024, 6 in 2025, and 3 year-to-date in 2026—with combined potential value across all awards (prime and sub) reaching $235.5 million. Combined obligated dollars ($361.7 million) exceed combined potential value, indicating significant performance on mature awards.

As a subcontractor, Stellar engages primarily with large defense and aerospace primes. Booz Allen Hamilton has subcontracted Stellar for space systems engineering across multiple task orders, including Space Systems Command Ground Systems Engineering and Integration Support (GSIS) work and Research, Systems, and Engineering Integration (RS SEI) modifications. Stellar also subs to Northrop Grumman Systems Corp on the Ground-Based Strategic Deterrent (GBSD) Engineering and Manufacturing Development program (awards dated April 2, 2025, and January 28, 2026), to Deloitte Consulting LLP for NASA Space Technology Mission Directorate and Moon to Mars architecture technical and program management support (January 2026 and earlier), to Lockheed Martin on the Next Generation Overhead Persistent Infrared Geosynchronous Phase 2.1A and Multi-Slit Solar Explorer thermal engineering work, and to The Boeing Company on the Evolved Strategic Satellite Communication Prototype program. Additional subcontract primes include KBR Wyle Services, Columbus Technologies and Services, Space Network Solutions, Science Systems and Applications, Salient Crgt, Kratos Technology & Training Solutions, and Tecolote Research. The vendor's historical sub work with Tecolote on space and missile systems acquisition management support dating to November 2021 reflects sustained engagement in acquisition advisory roles alongside core engineering delivery.

On the GSA Schedule, Stellar offers 22 active labor categories spanning engineering grades (bachelor's through master's education, 0 to 25 years experience) with hourly rates from $109.23 for entry-level engineering support to $462.97 for subject-matter expert roles at the senior master's level. No security-cleared labor is offered on the GSA vehicle. Service Contract Inventory data captures only 12 prime and 15 named subcontractor SCI records (27 total) in FY2022 through FY2024, reflecting the vendor's heavy reliance on GSA Schedule and IDIQ task-order work, which often fall outside SCI's $150,000-and-above reporting scope or are structured as delivery orders rather than standalone service contracts. SCI-reportable invoiced revenue ran to $0 across all three fiscal years in the source; the FTE trajectory shows 15.2 FTEs in FY2022, dropping to zero in FY2023, and recovering to 8.7 FTEs in FY2024, indicating sparse coverage of the vendor's true federal services footprint.
