ATK Launch Systems LLC

ATK Launch Systems LLC Propulsion Systems - Promontory Division, operating as ATK Launch Systems-Promontory, manufactures solid rocket motors, propulsion components, and related engineering and testing services for the Department of Defense and NASA as a prime contractor. The company is a wholly owned subsidiary of Northrop Grumman Innovation Systems LLC, a manufacturer of guided missiles, space vehicles, and propulsion systems, and competes exclusively in full-and-open procurements with no set-aside designations across its entire federal footprint.

ATK Launch Systems-Promontory's capability portfolio centers on solid rocket propulsion development, production, sustainment, and testing. Concrete work includes motor static fire testing (SR118, SR119, SR120, M55, M57 motors), propellant properties testing and analysis, igniter dissection and evaluation, motor component disposal and disassembly, test stand equipment design and repair, and specialized engineering studies supporting aging surveillance of legacy missile and space systems. The company also provides production and operations support for NASA's Space Launch System booster program. Representative prime work includes a $4.34 million core effort delivery order from the Space and Missile Systems Center (SMC) issued September 2024 for broad propulsion system supplies and services under Performance Work Statement paragraphs; a $1.78 million cost-plus-fixed-fee delivery order from SMC awarded September 2025 to design and develop three hydraulic test carts for aging surveillance sustainment; a $1.44 million firm fixed-price delivery order from SMC issued September 2024 for 750 hours of SR118 and SR120 motor static fire testing; and a $2.90 million delivery order from SMC issued April 2026 for testing supporting Minuteman and Peacekeeper rocket motor sustainment, including motor static fire testing, propellant properties testing and analysis, igniter dissection and evaluation, and related engineering support. The company also performed work on the Space Launch System booster production and operations contract through NASA's Marshall Space Flight Center.

Customer concentration is heavily weighted to defense space and propulsion programs. The Space and Missile Systems Center leads by award count (159 awards, $188.2 million combined potential value), but NASA's Marshall Space Flight Center dominates dollars (13 awards, $4.28 billion combined potential value) anchored on SLS booster work. The Air Force Materiel Command Nuclear Weapons Center, Air Force Research Laboratory, and Army Materiel Command round out the top five customer agencies by dollar value. Across the 824 total awards in source data spanning 1980 to present, the top five customers by potential value account for 94% of combined value, with Marshall Space Flight Center alone representing approximately 84% of the total $5.12 billion combined potential value. This concentration reflects the company's strategic role as a critical solid rocket propulsion supplier to the SLS program and related strategic missile sustainment efforts.

ATK Launch Systems-Promontory places task orders against multiple Air Force indefinite delivery vehicles. The top parent vehicles include IDC FA881818D0001 (67 task orders, $43.7 million combined potential value), IDC FA881806D0022 (37 task orders, $25.4 million combined potential value), IDC FA881806D0021 (24 task orders, $11.5 million combined potential value), and IDC FA881806D0031 (20 task orders, $13.7 million combined potential value). These SMC-managed vehicles provide recurring access to sustainment and testing work across Minuteman, Peacekeeper, and Space Launch System programs.

Activity trajectory shows modest recent volume with three awards each in 2025 and 2026 year-to-date, down from 17 in 2024 and 15 in 2023. Eleven awards with ultimate completion dates in the next twenty-four months carry a combined potential value of $11.9 million in recompete exposure. The vendor's historical award footprint since 1980 demonstrates sustained engagement; the recent slowdown in annual award counts reflects the completion phases of larger programs rather than customer attrition.

The company's top NAICS categories are Guided Missile and Space Vehicle Propulsion Unit and Propulsion Unit Parts Manufacturing (130 awards), Explosives Manufacturing (41 awards), and All Other Miscellaneous Chemical Product and Preparation Manufacturing (40 awards), anchoring the company's identity as a specialized solid propellant and motor manufacturer. Place of performance for all named work is Corinne, Utah, where ATK Launch Systems-Promontory maintains test stands, motor static fire facilities, and engineering operations supporting SMC and Marshall Space Flight Center programs.
