About Caribou Thunder, LLC
Caribou Thunder LLC, a women-owned small business and HUBZone firm headquartered in Hayward, Wisconsin, operates as a defense engineering subcontractor, delivering software development, systems engineering, and technical services to the Department of Defense. The vendor holds a Subchapter S corporation structure and is certified as a minority-owned, self-certified small disadvantaged business; it competes across full-and-open vehicles rather than predominantly through set-asides, though its WOSB and HUBZone designations are available for set-aside competition.
Caribou Thunder's footprint is almost entirely sub-contract work — 99% of its 209 recent awards are subcontracts. The three prime awards are recent and structurally significant: an Indefinite Delivery Indefinite Quantity contract award of $151 billion ceiling from the Missile Defense Agency for the Scalable Homeland Innovative Enterprise Layered Defense (SHIELD) vehicle awarded December 29, 2025, with an initial delivery order of five hundred dollars in performance, plus one additional prime contract IDV. The SHIELD IDIQ spans research and development, prototyping, systems engineering, weapon design, production, test and evaluation, cybersecurity, and modernization across multi-domain defense capabilities — air, missile, space, cyber, and hybrid domains — with a ten-year performance period running through December 28, 2035. Place of performance on the initial SHIELD task order is Huntsville, Alabama.
Caribou Thunder's customer concentration is dominated by the Missile Defense Agency, which accounts for 140 awards (67% of the footprint) with a combined potential value of five hundred dollars, a disconnect that signals high-volume task order activity against a minimal initial ceiling. The Department of the Air Force Air Combat Command (23 awards), Defense Information Systems Agency (13 awards), and the Air Force Space and Missile Systems Center (12 awards) follow. The vendor also holds subcontracts under Defense Logistics Agency Troop Support, which carries one award valued at $26 million. By top customer potential value, DLA Troop Support dominates the dollar volume despite low award count, while MDA anchors volume. Top work categories span custom computer programming services (113 awards), research and development in physical and engineering sciences (58 awards), and computer systems design (13 awards).
Caribou Thunder subcontracts almost exclusively to Northrop Grumman Systems Corporation, which accounts for the vast majority of its subcontracting footprint across task orders ranging from June 2023 through January 2026. Representative Northrop Grumman sub work includes ballistic missile defense system software development and sustainment — specifically maintaining, sustaining, and developing the Ballistic Missile Defense International Simulation (BMD I-SIM), Missile Defense Space Warning Tool (MDST), and Threat Modeling Center (TMC) production software; Global Command and Control System–Joint (GCCS-J) software sustainment and modernization; and Missile Defense Space Warning Tool operation for early warning training and warfighter exercise support. Additional subcontracting appears under DCS Corporation for technical and engineering services supporting the Combat Capabilities Development Command Ground Vehicle Systems Center Ground Vehicle Robotics Group, with work on the Warfighter Machine Interface (WMI) Productization project to analyze, test, and document Scalable Solider Machine Interface core components; smaller sub work flows through Lockheed Martin Corporation, Science Applications International Corporation, and General Dynamics Global Force, LLC covering overhead persistent infrared labor, systems engineering, and JWARN sustainment.
On SCI-reportable federal service contracts, Caribou Thunder shows limited volume — eight records across fiscal years 2022 through 2024, all as named subcontractor. The vendor's SCI-tracked workforce grew from 4.9 FTEs in FY2022 to 8.5 FTEs in FY2024, a modest but consistent trajectory that reflects deep sub-engagement rather than prime service contract delivery.
Activity has surged dramatically in 2025, driven almost entirely by the SHIELD award and its initial task order. The vendor recorded 5 awards in 2022, 24 in 2023, and 22 in 2024, then 133 awards in 2025 — primarily task orders under the SHIELD IDIQ and subordinate sub-awards from Northrop Grumman. Parent vehicles through which Caribou Thunder places orders include the core SHIELD Indefinite Delivery Contract (89 task orders), the Systems Engineering Technology and Innovation vehicle (13 task orders), and several Air Force IDCs. The combined potential value across all 209 awards is $26 million, though obligated dollars exceed potential value at $27.8 million, indicating significant task order drawdown activity and contract maturity.
