Cross Field Amplifier (CFA) Electron Tubes

The Department of the Navy Naval Supply Systems Command established a master IDIQ on June 27, 2022 to analyze, rebuild, convert, test, and manage configuration of Crossed Field Amplifier electron tubes used in the Aegis Weapon System, with ordering authority through June 26, 2027. Approximately 11 months of ordering authority remain. The vehicle is unrestricted (no set-aside), and competition is concentrated: Stellant Systems Inc. holds eight orders valued at $35.5 million combined potential, while CPI Electron Device Business, Inc. holds six orders valued at $24.3 million combined potential—the only two awardees under the vehicle.

The vehicle has obligated $54.1 million against a combined potential value of $59.9 million, representing 90% utilization. Task-order volume has declined from five orders in the award year (2022) to one order in 2026, though individual order values remain substantial. Recent orders repair specific electron tube variants: double-duty cross field amplifiers (NSN 5960-01-322-8417), water-cooled vane cross field amplifiers (NSN 5960-01-487-2175), and single-duty cross field amplifiers (NSN 5960-01-605-9921). Ceiling values across the portfolio range from approximately $781,000 to $6.5 million, with firm fixed pricing throughout. The most recent award, on March 27, 2026, was a $6.12 million delivery order to repair double-duty tubes with completion by November 30, 2026.

Naval Supply Systems Command Weapons Systems Support at Mechanicsburg funds 11 of 14 orders ($53.2 million combined potential), while the Defense Contract Management Agency funds the remaining three ($6.7 million combined potential). All task orders are direct repair work, predominantly firm fixed price. The vehicle's narrow awardee base and declining order velocity suggest a mature or winding-down program supporting a legacy weapons system with a defined, limited scope.
