About Scix3 LLC
Scix3 LLC, operating under the doing business as name Cslabs, is a minority-owned, SBA-certified 8(a) small disadvantaged business based in Alexandria, Virginia. The company specializes in advanced technology research and development, with particular expertise in machine learning, autonomous systems, microelectronics, and innovative defense solutions. Scix3 LLC has established itself as a prime contractor to the federal government, primarily serving the Department of Defense and its subordinate agencies through the Small Business Innovation Research (SBIR) program and other research-focused contract vehicles.
Scix3 LLC's federal contract portfolio demonstrates substantial expertise in cutting-edge defense technology development across multiple domains. The company has received prime SBIR Phase I and Phase II awards from both the Department of the Army and the Department of the Navy, totaling over $4.2 million in contract value across its known active and recently completed awards. Notably, the company was awarded a $1,999,735.66 cost-plus-fixed-fee Phase II SBIR contract from the Office of Naval Research for next-generation autonomy research on unmanned maritime vehicles, with performance extending through September 2027. Additionally, Scix3 LLC received a $1,699,945.21 firm fixed-price Phase II SBIR contract from the Department of the Army for machine learning applications in height of burst scoring, supporting the Army's multi-domain operations objectives. More recently, the Naval Sea Systems Command awarded Scix3 LLC a $239,572 Phase I SBIR contract for research supporting the Space-Based Infrared System High (SBIRS High) program, a critical Major Defense Acquisition Program. All of these awards were designated as total small business set-asides, reflecting the company's qualification as a small business and its participation in SBA contracting programs.
Scix3 LLC holds a prime position on the SeaPort-NxG (SeaPort Next Generation) Indefinite Delivery/Indefinite Quantity (IDIQ) contract, a $4 billion multiple-award vehicle issued by the Naval Sea Systems Command with an ordering period through January 2029. Under this contract vehicle, which serves as a parent master IDIQ, Scix3 LLC is positioned to compete for and execute task orders providing research, engineering, and technical services across a wide range of naval and marine technology domains. The contract enables task order competitions involving NAVSEA and its partner Navy Systems Commands, including Naval Air Systems Command (NAVAIR), Naval Information Warfare Systems Command (NAVWAR), Naval Facilities Engineering Systems Command (NAVFAC), Naval Supply Systems Command (NAVSUP), the Office of Naval Research (ONR), and the United States Marine Corps (USMC).
