Momentus Space LLC

Momentus Space LLC, a San Jose-based commercial space technology company, operates as a prime contractor on federal space launch, orbital service vehicle, and payload integration contracts across NASA and Department of Defense agencies, competing in full-and-open procurements without set-aside designations. The for-profit limited liability company manufactures advanced space technologies and orbital solutions, with 94% of recent awards issued as prime contracts and the remainder as grant sub-awards.

Momentus has secured a commanding position on two marquee federal space vehicles. NASA's Kennedy Space Center awarded a $300 million Venture-Class Acquisition of Dedicated and Rideshare (VADR) indefinite delivery contract on August 22, 2024, running through January 2032, which anchors the vendor's portfolio; a corresponding $300 million delivery order was issued the same day for payload integration and orbital service vehicle support across low Earth orbit and cislunar environments. The Missile Defense Agency awarded a $151 billion multiple-award Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) indefinite delivery indefinite quantity contract on December 29, 2025, extending through December 2035, with an initial five-hundred-dollar delivery order in that same award. Momentus also holds a $45 million indefinite delivery contract from NASA's Armstrong Flight Research Center (awarded March 1, 2024, running through February 2029) for suborbital and hosted orbital flight and payload integration services supporting technology demonstrations across low Earth orbit, geostationary orbit, and cislunar space. Under the Armstrong contract, Momentus has received five delivery orders totaling $8.5 million, including a $5.15 million firm fixed-price order for integration and flight of the T0426 Commercial Orbital System for Microgravity In-Space Crystallization (COSMIC) payload, a $2.54 million order for integration and flight testing of the T0428 Juno Rotating Detonation Rocket Engine, and a $395,798 order for Generation 1 solar sail mission concepts.

Customer concentration is extreme. Kennedy Space Center accounts for 3 awards carrying $600.1 million in combined potential value — nearly all of the vendor's total pipeline of $662.1 million. Armstrong Flight Research Center (6 awards, $53.5 million combined potential value) is the second-largest customer by count but distant in dollars. The Air Force, Missile Defense Agency, and Defense Advanced Research Projects Agency round out an active set of seven distinct customer agencies. The vendor's total obligated value across all awards stands at $16.7 million (3% of combined potential value), indicating most awards are unapproved, future work.

Momentus also holds a $4.67 million multiple-award Other Transaction Indefinite Delivery Vehicle from the Defense Advanced Research Projects Agency (awarded May 2, 2024) supporting the Novel Orbital and Moon Manufacturing, Materials and Mass-Efficient Design (NOM4D) program for advanced space technology solutions in cislunar and lunar environments. Recent other-transaction work includes a $1.94 million Air Force agreement (awarded August 2023) for orbital service vehicle enhancements to meet Department of Defense mission requirements and a $20,000 Air Force HALO program OTA (awarded September 2024). Earlier SBIR Phase II work for the Air Force Research Laboratory (awarded June 2025, $1.86 million, completion January 2027) focused on establishing a framework for space sustainment and maneuver across all orbital regimes, including cislunar travel.

Activity has accelerated sharply — one award in 2020, one in 2023, six in 2024, seven in 2025, and one in the first months of 2026. Five awards with ultimate completion dates in the next twenty-four months carry $309.6 million in combined potential value, representing significant recompete exposure anchored by the Kennedy Space Center VADR contract. A single grant sub-award appears in the portfolio: Momentus is a sub-recipient under a University of Colorado grant (awarded May 1, 2026), which provides limited visibility into grant-program engagement. The vendor's primary NAICS footprint centers on nonscheduled chartered freight air transportation (9 awards) and research and development in physical, engineering, and life sciences (3 awards), with PSC codes dominated by space transportation/launch services (8 awards) and national defense R&D (4 awards).
