Stellar Science LTD. CO.

Stellar Science LTD. CO. (doing business as Stellar Science Co., LLC), a veteran-owned small business based in Albuquerque, New Mexico, develops physics-based simulation software, computational electromagnetics modeling tools, and advanced scientific software for defense and space research agencies as a prime contractor on 101 awards (95% of recent footprint) and as a subcontractor on five awards. The vendor competes predominantly full-and-open across its prime portfolio, with total small business set-asides concentrated in SBIR/STTR phase work rather than recurrent prime contracts.

Stellar Science's capability portfolio centers on high-fidelity physics-based simulation, directed energy systems modeling, multi-domain modeling and analysis tools, computational electromagnetics, and custom scientific software development for defense research and development. The vendor anchors its practice on the Air Force Research Laboratory, where it holds a $48 million single-award indefinite delivery contract for the Advanced Framework for Simulation, Integration and Modeling (AFSIM) program and recently received an $85 million AFSIM FORGE contract awarded December 19, 2025, with a 50-month period of performance running through August 20, 2029. Representative prime work includes a $24.9 million cost-plus-fixed-fee definitive contract from AFRL for Modeling Applications for Next-Tier Initiatives and Capabilities of Realistic Engagements (MANTICORE) through April 22, 2029; a $7.5 million AFRL contract for Advanced Laser Modeling and Simulation 2 (ALMS2) supporting laser source and beam control physics; a $6.4 million AFRL definitive contract for the Varied Interface and Phenomenology Engineering Relationship Suite (VIPERS); and a $4.36 million Other Transaction Agreement with AFRL for the GALAXY (JDETO) SBIR Phase III program. Stellar Science also maintains active delivery orders under the original AFSIM IDC, including $11.4 million for REBASE Foundation and Expansion III, $5.7 million for Foundation & Expansion II, and multiple task orders supporting model and integration testing across NASA Ames and AFRL. In SBIR/STTR work, the vendor holds Phase II contracts from AFRL for RATE-EM ($1.25 million), PYTHIA ($999 thousand), and RING 2 ($749 thousand), as well as Phase II awards from the Missile Defense Agency for Advanced Simulation of Hypersonics (ASH Phase II, $1.97 million) and from the Army Research, Development and Engineering Command for reinforcement learning-based algorithms ($1.1 million).

Customer concentration is dominated by the Air Force and its subordinate commands. The Department of the Air Force and the Air Force Materiel Command Research Laboratory account for 82% of recent awards (87 awards combined, $287.4 million combined potential value across the top five customer agencies, which covers 97% of total potential value). Within that set, AFRL places the greatest volume (56 awards, $118.2 million) and the Department of the Air Force (prime issuer) anchors the largest dollar value (7 awards, $169.2 million). NASA Ames Research Center holds eight awards with $23.9 million in combined potential value, including delivery orders for Model and Integration Test II tasks ($499 thousand, $299 thousand, $185 thousand, and $1.6 million). The Missile Defense Agency rounds out the active set with ten awards totaling $4.6 million, including SBIR Phase I and Phase II work in hypersonics simulation and autonomous swarm intercept modeling. The Navy and Army account for smaller footprints (Naval Strategic Systems Programs, $240 thousand; Naval Air Warfare Center, $240 thousand; Army RDECOM, $1.1 million across two awards). Notably, 15 distinct customer agencies appear across the portfolio, but the top two (Air Force entities) represent approximately 86% of combined potential value.

Stellar Science's parent vehicle position is anchored to the AFSIM family. The new AFSIM FORGE multiple-award IDC (awarded December 19, 2025) represents the successor vehicle for scaling and maturing the original AFSIM architecture across Wright-Patterson Air Force Base and subordinate locations. The vendor also places task orders under five other active IDCs with the Air Force Materiel Command Research Laboratory (IDCs FA860409D7490, 80ARC020D0004, FA865021D2621, and FA945108D0275), with combined ordering activity of 16 task orders valued at $30.3 million. These vehicles support ongoing physics-based simulation, software development, and research engineering across directed energy, multi-domain modeling, and computational electromagnetics domains.

Activity has grown modestly but consistently over five years (three awards in 2021 to thirteen in 2024, with ten awards through mid-2025). Nine awards with combined potential value of $42.6 million face ultimate completion within the next twenty-four months, presenting material recompete exposure; these include ALMS2 ($7.5 million), HPEM ($3.7 million), the RATE-EM Phase II definitive ($1.25 million), several Phase I SBIR/STTR efforts, and delivery orders under existing AFSIM and NASA Ames IDCs. The vendor's obligated dollars (40% of combined potential value, or $132.4 million) signal active execution across the portfolio.

In its subcontractor role, Stellar Science provides directed energy bio-effects research and analysis services to General Dynamics Information Technology on two recent sub-awards (December 2025, January 2024), pulsed and continuous-wave innovation support to BAE Systems Space & Mission Systems on a January 2024 sub task, electro-optical and infrared analytic tool development and sustainment to Modern Technology Solutions under National Air and Space Intelligence Center support (September 2023), and systems analysis to Linquest Corporation supporting United States Space Force reporting (September 2023). The subcontract footprint accounts for only 5% of total awards by count but represents secondary capability extensions rather than a core business model.

The vendor's award portfolio reflects a specialized and sustained research engineering practice anchored to Air Force directed energy and simulation modernization priorities, with secondary expansion into civil space science (NASA Ames) and defense agency innovation programs (SBIR/STTR, MDA). All work is performed in Albuquerque, New Mexico. Stellar Science operates as a sole proprietorship structured as a limited liability company with veteran-owned designation carrying full and open competition positioning across its prime awards.

Stellar Science develops custom cross-platform scientific modeling, analysis, and visualization software for spacecraft analysis, image processing and computer vision, computer-aided design (CAD) software, and physical systems modeling and simulation.
