Cross Field Amplifier (CFA) Electron Tubes

The Cross Field Amplifier (CFA) Electron Tubes Indefinite Delivery/Indefinite Quantity (IDIQ) contract is a specialized federal contract vehicle awarded by the Naval Supply Systems Command Weapons Systems Support (NAVSUP WSS) for the comprehensive maintenance and repair of critical electron tubes used in naval weapon systems, specifically focusing on cross-field amplifiers. The contract covers analyzing, rebuilding, converting, testing, quality assurance, configuration management, and administrative requirements for electron tubes utilized in the Aegis Weapon System. The original sources sought notice identified three specific National Stock Number (NSN) electron tube types: double duty cross-field amplifiers, water-cooled vane cross-field amplifiers, and single duty cross-field amplifiers.

Task orders under this IDIQ demonstrate a consistent pattern of firm fixed-price delivery orders ranging from approximately $781,699 to $6,525,600, with ultimate completion dates typically extending 1-2 years from the award date. Two primary prime contractors have been awarded multiple task orders: Stellant Systems Inc. (a subsidiary of L3Harris Technologies) and CPI International, Inc.'s Beverly Microwave Division. The contract has been utilized by the Naval Supply Systems Command and the Defense Contract Management Agency (DCMA), with all recent task orders showing no specific small business set-aside designations. Work is predominantly performed in Pennsylvania (Williamsport, at Stellant Systems) and Massachusetts (Beverly and Woburn, at CPI), focusing on the repair and maintenance of specialized electron tubes critical to naval electronic systems such as the Aegis weapons platform.
