Integrated Support Systems Inc.

Integrated Support Systems Inc., a self-certified small disadvantaged business based in Seneca, South Carolina, is the original equipment manufacturer and sole provider of SLICwave, a proprietary logistics and sustainment planning software platform used across the Department of Defense and NASA. ISS operates predominantly as a prime contractor (97% of its 169 recent awards) delivering software licensing, maintenance, technical support, and training services without reliance on small business set-asides — all awards in the source carry "No Set-Aside Used" designations, reflecting ISS's position as the sole source for its proprietary platforms.

ISS maintains a heavily concentrated customer base anchored by Naval Air Systems Command (NAVAIR), which accounts for 79 awards valued at $15.4 million in combined potential value — approximately 84% of ISS's total $18.3 million award portfolio. The Naval Air Warfare Center follows with 23 awards ($1.2 million), and NASA's Shared Services Center with 9 awards ($880 thousand), covering 99% of the vendor's combined potential value across 12 distinct customer agencies. This concentration reflects the specialized, proprietary nature of SLICwave, which is utilized by NAVAIR, Naval Sea Systems Command (NAVSEA), Naval Supply Systems Command, and NASA for maintenance planning and product supportability analysis across Navy and aerospace programs.

The centerpiece of ISS's prime work is a $5.44 million single-award Indefinite Delivery Contract with NAVAIR running through June 2029, under which three delivery orders totaling $1.18 million have been issued to date for SLICwave lifecycle components, software licensing (covering over 200 licenses distributed across multiple sites), annual maintenance, technical support, and user training. Representative prime awards include a $639,088 delivery order modification to NAVAIR (June 2025) for lifecycle product support and training, a $405,940 purchase order from Naval Facilities Engineering Command (September 2025) for software and maintenance services, a $213,230 sole-source purchase order from NASA (October 2025) for a SLICwave Level 2 PPAL license, and a $98,400 firm fixed-price order from NASA (October 2025) for SLICwave user licenses with comprehensive maintenance and technical support through September 2028.

Recent activity shows a mixed trajectory: two awards in 2022, ten in 2023, five in 2024, seven in 2025, and one in 2026 year-to-date, with four awards (combined potential value $854 thousand) facing ultimate completion dates within the next twenty-four months. ISS also maintains a subcontractor presence with major primes including Bell Boeing Joint Project Office on V-22 engineering and logistics sustainment support (December 2025), Bell Textron on Future Vertical Lift development (October 2025), Sierra Nevada Company on Survivable Airborne Operations Center services (November 2024), and Argon ST on product support (September 2023). The vendor has generated $15.1 million in obligated dollars against its $18.3 million potential-value portfolio (82% obligation rate), supporting the proprietary SLICwave platform's role as critical infrastructure across DoD logistics and NASA mission-support operations.
