Stellant Systems Inc.

Stellant Systems Inc., operating through its L3 Electron Devices division and doing business as Electron Devices, is a large-business manufacturer of specialized microwave and radio frequency components—primarily traveling wave tubes (TWTs), amplifiers, and electron tubes—that serves the Department of Defense as a prime contractor (77% of recent awards) and as a subcontractor to major defense primes. The company is a subsidiary of L3Harris Technologies, headquartered in Torrance, California, competing in full-and-open procurements with no small business set-asides across its recent prime footprint.

Electron Devices' capability portfolio centers on the design, manufacture, and repair of advanced electronic components for defense systems. Representative prime work includes a $20.1 million delivery order from Naval Supply Systems Command (March 2026) for electron tube manufacturing and supply, a $13.99 million single-award indefinite delivery contract from Air Force Sustainment Center (September 2024) for Band 5 traveling wave tube repair for B-1 Lancer ALQ-161 electronic warfare systems, a $12.2 million single-award IDC from Naval Sea Systems Command (September 2024) for Q-band TWT amplifier module design, engineering, and production, and a $36.96 million multiple-award IDC from Ogden Air Logistics Complex (September 2022) for F-16 APG-68 traveling wave tube teardown, test, evaluation, and repair. Additional recent prime awards include a $9.4 million delivery order from Naval Supply Systems Command (February 2024) for electron tube components, $6.86 million for electron tubes and assemblies from Ogden Air Logistics Complex (September 2021), and a $3.78 million delivery order from Air Force Sustainment Center (September 2024) for B-1 Band 5 TWT repair.

Customer concentration splits between naval and air force logistics operations. The top five funding offices account for 76% of combined potential value: Ogden Air Logistics Complex (28 awards, $124 million combined potential value), Naval Supply Systems Command (29 awards, $86 million), Air Force Sustainment Center (22 awards, $63.6 million), Secretary of the Navy Office of Naval Research (13 awards, $45.4 million), and Naval Sea Systems Command (22 awards, $35.6 million). The two customer rankings diverge meaningfully on volume versus dollars—NAVSYSCOM and Naval Air Warfare Center place many smaller repair and supply orders, while Ogden and AFSC anchor the largest IDC vehicles and delivery orders.

Electron Devices holds five named IDVs worth $81.27 million in combined ceiling value: the $36.96 million Ogden F-16 APG-68 multiple-award IDC (two task orders issued to date, $1.83 million combined), the $17.9 million Ogden traveling wave tubes single-award IDC (one task order, $6.86 million), the $13.99 million Air Force Sustainment Center B-1 Band 5 TWT repair single-award IDC, the $12.2 million NAVSEA Q-band TWT amplifier single-award IDC, and a Naval Supply Systems Command multiple-award basic ordering agreement for F-18 guided TWT products (one delivery order, $9.4 million). The source also references participation in multiple additional IDCs under PSC codes for electron tubes, repair/rebuild, and electronic countermeasures equipment.

Activity has grown from five awards in 2022 to twenty-four in 2024, with fourteen awards issued in 2025 and five through mid-2026. Six awards with combined potential value of $39.8 million face ultimate completion within the next twenty-four months, exposing the prime to recompete risk on those vehicles. In its subcontractor role, Electron Devices delivers traveling wave tubes and major assemblies to Raytheon Company on PATRIOT air-defense system spare-parts, AMRAAM missile production lots, and C-band radar transmitter programs; provides TWT support to Northrop Grumman Systems Corporation on commercial resupply services and space exploration augmentation modules; and subcontracts to Dynetics on airborne threat simulation programs. The parent vendor, Ship Analytic Usa, Inc., also holds a named subsidiary, Stellant Pst Corp., which is a manufacturer of goods but does not appear in the award detail. Across NAICS classification, Electron Devices' primary categories are other electronic component manufacturing (41 awards), other electronic and precision equipment repair and maintenance (34 awards), and other aircraft parts and auxiliary equipment manufacturing (29 awards), with secondary research and development and search/detection/navigation system work.
