Sierra Lobo Inc.

Sierra Lobo Inc., a minority-owned small disadvantaged business headquartered in Fremont, Ohio, delivers advanced aerospace engineering, space technology development, and test operations support to federal agencies as a prime contractor (89% of recent awards) and subcontractor, with established expertise in nuclear power systems, rocket propulsion, cryogenic testing, and human spaceflight infrastructure. The company competes predominantly under total small business set-asides across its prime footprint, holding positions on major NASA, Air Force, Navy, and GSA vehicles.

Sierra Lobo's customer concentration centers heavily on NASA and Department of Defense agencies. The top five customers by potential value account for 100% of the combined portfolio, driven by two outlier awards: Naval Sea Systems Command (6 awards, $76.55 billion combined potential value, dominated by a Seaport-NXG IDIQ with a $4 billion ceiling) and the Department of the Air Force (8 awards, $46.04 billion, anchored by an Eglin Wide Agile Acquisition Contract vehicle with a $46 billion ceiling). By award count, NASA Glenn Research Center dominates with 57 awards and $1.01 billion combined potential value; NASA Johnson Space Center, NASA Kennedy Space Center, and the Air Force Research Laboratory round out the active set. This divergence between count and dollar rankings reflects the presence of large-ceiling IDIQs alongside numerous smaller task orders and research grants.

Sierra Lobo holds positions on multiple high-value parent vehicles. The top vehicle by task-order count is Indefinite Delivery Contract NNC05CA95C (28 task orders, $369.8 million combined potential value), a NASA Glenn Research Center contract. The vendor also operates under Indefinite Delivery Contract DEAM2401OH20130 (10 task orders), NNC07BA01B (10 task orders, $545 thousand), NNC04BA11B (6 task orders, $1.4 million), and W31P4Q07D0022 (5 task orders, $39.4 million). Beyond these, Sierra Lobo holds a $282.2 million single-award NASA Glenn contract (awarded March 1, 2025, running through March 1, 2028) for technology development hardware and software, space flight hardware, ground support equipment, and operational support—under which two recent delivery orders (DO-14-304 and DO-14-305, each cost-plus-fixed-fee) total $75.7 million for Space Reactor-1 Freedom nuclear power module power conversion system engineering and are scheduled to complete December 31, 2027. The vendor also holds a $666 million single-award NASA Johnson Space Center IDV (awarded November 15, 2021, through January 31, 2028) for hazardous testing, infrastructure maintenance, and construction at the White Sands Test Facility. On the Air Force side, Sierra Lobo holds the Eglin Wide Agile Acquisition Contract (awarded March 13, 2025, $46 billion ceiling through September 9, 2031, NAICS 332993) and an OASIS SB delivery order from December 1, 2022, valued at $44.3 million for rocket technology engineering at Edwards Air Force Base, California, completing January 31, 2029, with subcontractors Wardle Enterprises, Sparc Research LLC, and Boyle Enterprises providing specialized propulsion and lab support. GSA-administered vehicles include OASIS+ Total Small Business (awarded December 19, 2024, no specified ceiling, through December 18, 2029) and OASIS+ Unrestricted (awarded December 17, 2024, no specified ceiling, through December 16, 2029). On the Navy side, Sierra Lobo holds a Seaport-NXG multiple-award IDIQ (awarded January 2, 2025, $4 billion ceiling through January 1, 2029, NAICS 541330, place of performance Fremont, Ohio). Sierra Lobo also participates in the AEDC Velocity Alliance Consortium as a base member (awarded July 1, 2026, Air Force, Other Transaction IDV, no funded ceiling).

Recent capability examples include two $37–$38 million delivery orders from NASA Glenn (August 28, 2026, both cost-plus-fixed-fee, total small business set-aside) for Space Reactor-1 Freedom nuclear power conversion system engineering, completing December 31, 2027, and an $18.6 million fixed-price level-of-effort delivery order from NASA Stennis Space Center (July 1, 2025, total small business set-aside, ultimate completion November 9, 2026) for test operations support and operation of high-pressure industrial water, high-pressure gas, and cryo propellant storage areas. Sierra Lobo also received a $559,643 project grant from the Office of Naval Research under the Basic and Applied Scientific Research program (CFDA 12.300, awarded September 1, 2026, through March 31, 2028) for Bichromatic Littoral Temperature Observer (BALTO) operations, and a $413,564 NASA grant (awarded April 1, 2024, through December 31, 2026) for development of a Microgravity Lab Assistant, a compact robot for sample preparation on the International Space Station. On the Air Force Research Laboratory front, Sierra Lobo pursued SBIR Phase I work, including a $49,950 award (February 10, 2022) for low-cost small satellites with thermal infrared ISR capability. Through the Office of Naval Research, Sierra Lobo holds a $2.2 million SBIR Phase II research and development contract (awarded September 12, 2023, extended through March 12, 2026, total small business set-aside, cost-plus-fixed-fee).

Activity has grown from three awards in 2022 to eleven in 2025, with eight awards in 2026. Five awards carrying $94.4 million in combined potential value face ultimate completion within the next twenty-four months, exposing the vendor to moderate recompete risk concentrated on the NASA Glenn and Johnson Space Center relationship.

SCI-reported invoicing of $10 million across FY2022–FY2025 reflects partial visibility into Sierra Lobo's federal service-contract footprint. The vendor reported $5.2 million invoiced in FY2022 across 26.4 FTEs on prime contracts and $4.8 million in FY2025 across 33.9 FTEs, with FY2023 and FY2024 showing minimal SCI-reportable prime activity. Across SCI-reportable prime contracts, government-paid hourly rates ran around a median of $81.34 per hour, with rates spanning from roughly $71 per hour (10th percentile) to $92 per hour (90th percentile), positioning Sierra Lobo in the mid-range for technical and engineering labor. The vendor performed approximately 98% of contractor hours in-house on SCI-reportable prime contracts, with subs handling around 2% of total hours; two named subcontractors appear in the SCI dataset.

In its subcontractor capacity, Sierra Lobo performs electrical systems engineering design and assembly support under Science Systems and Applications Inc. on the Electrical Engineering Systems Services III (ESES III) NASA contract (multiple sub-awards October 31, 2023), multidiscipline engineering support under Space Network Solutions LLC (February 23, 2024), and structural engineering work under Bechtel National on the Space Launch System Mobile Launcher 2 design and construction (December 13, 2021). Sierra Lobo also subcontracts under NASA's internal GEARS contract (multiple engineering research and scientific support sub-awards through 2026) and under Pinnacle Construction Development Group on ATF Cryogenic Facility services (September 29, 2025). As a sub-grantee, Sierra Lobo performs space robotics research under the University of Cincinnati on a multi-year project spanning contact operations and servicing technologies (amendments through September 21, 2026).

Set-aside posture shows strong concentration in total small business designations, with recurring 8(a) eligibility and SDB status anchoring both prime and sub positions. The vendor's category concentration reflects the research and development, facilities support, and engineering-services nature of the work: Research and Development in Physical, Engineering, and Life Sciences (38 awards), Facilities Support Services (29 awards), and Engineering Services (23 awards) lead the NAICS breakdown, while Technical Representative and Support—Professional Engineering / Technical PSC codes dominate the services classification.
