Mastodon Design LLC

Mastodon Design LLC, a Rochester, New York-based subsidiary of CACI International Inc., manufactures and integrates advanced communications, electronic warfare, and signal intelligence equipment for the Department of Defense and civilian federal agencies as a prime contractor, competing without small-business set-asides across full-and-open and single-award indefinite delivery vehicles. The company does not pursue set-aside categories; 59% of its recent awards are prime contracts and 41% are subcontracts routed through other CACI entities and major defense primes.

Mastodon's core capability portfolio centers on ruggedized communications kits, direction-finding systems, and ground signal intelligence equipment for tactical and strategic applications. Representative prime work includes a $498.4 million single-award indefinite delivery contract with the Army's Program Executive Office for Intelligence, Electronic Warfare & Sensors (awarded June 28, 2024, extending through June 27, 2029) for production and fielding of the Terrestrial Layered System Brigade Combat Team Manpack—a brigade-level communications and electronic warfare system with L3Harris Technologies as the major subcontractor. Against this IDC, the Army has issued four delivery orders totaling approximately $134.8 million as of June 2026, including a $70.8 million order (August 5, 2025, due June 30, 2027), a $61.0 million minimum-buy order (June 28, 2024, due September 30, 2026), and two smaller orders in January 2026. Additional prime work includes a $3.54 million Air Force delivery order for the Joint Threat Warning System Ground SIGINT Kit Body Worn system (July 24, 2025), a $2.92 million Air Force delivery order for NARTHAX equipment (August 14, 2025), and a $1.84 million single-award Federal Communications Commission Blanket Purchase Agreement (June 15, 2023, expiring March 31, 2026) for Mastodon Standard Ground Equipment, accessories, training, and support—against which five task orders totaling approximately $978 thousand have been issued. Mastodon also supplies specialized equipment kits (Beast+, Kraken, Beast Standard Ground) to Army Space and Missile Defense Command, Drug Enforcement Administration, and other agencies under lower-value purchase orders.

Customer concentration is heavily weighted to defense and intelligence organizations. The top five funding agencies account for 65% of awards by count but 98% by potential value, with the Army's PEO Intelligence, Electronic Warfare & Sensors dominating the potential-value ranking at $636.3 million combined potential value across four awards—almost entirely the TLS BCT Manpack IDIQ and its delivery orders. The Air Force ranks second with 26 awards and $153.7 million potential value, followed by Special Operations Command ($12.7 million across 21 awards), Army Space and Missile Defense Command ($12.5 million across 17 awards), and Army Special Operations Command. This concentration reflects Mastodon's specialization in signal intelligence and electronic warfare systems for forward-deployed and special-operations users.

Mastodon holds positions on five named parent vehicles. The largest are two indefinite delivery contracts: IDC H9225417D0001, supporting 24 task orders with no stated ceiling in the source data, and IDC H9240120D0001, supporting 19 task orders with $53.4 million combined potential value. The vendor also operates under One Acquisition Solution for Integrated Services (12 task orders), IDC W911QY21D0015 (6 task orders, $6.8 million potential value), and the FCC BPA noted above. The indefinite delivery vehicles enable rapid task order placement across Army, Air Force, Special Operations, and other defense customers without full competition for each requirement.

Activity has remained volatile but persistent. Awards per year ranged from 16 in 2023 to 25 in 2024, with 17 in 2025 and 5 recorded through early 2026 in the source snapshot. The recompete cliff presents material risk: four awards with ultimate completion dates in the next twenty-four months carry combined potential value of $140.1 million, heavily skewed toward the TLS BCT Manpack delivery orders due in 2026 and 2027. Loss of this program would represent a significant revenue cliff for Mastodon, though the $498.4 million IDC itself extends through June 2029 and may support additional delivery orders.

In its subcontractor role, Mastodon delivers communications equipment, kits, components, and training to CACI parent entities (CACI NSS LLC, CACI Technologies LLC, CACI Inc. Federal), Lockheed Martin Corporation, Atlantic Diving Supply Inc., HII Mission Technologies Corp, Kratos S2 Inc., and Amentum Services Inc. across special operations support, logistics, naval modernization, and C4ISR programs. The sub-award footprint demonstrates Mastodon's role as both a captive supplier within the CACI ecosystem and an external vendor to prime contractors seeking specialized electronic warfare and communications expertise. A substantial portion of recent sub-awards flow to CACI-family entities, positioning Mastodon as an internal innovation and production center within the larger corporation.

Service Contract Inventory data cover only one year (FY2022) and one SCI-reportable record with $3.6 million invoiced—insufficient to characterize Mastodon's labor posture or subcontract engagement on service contracts. SCI is a partial view: it excludes the Mastodon equipment manufacturing, product sales, and delivery-order work that dominate the award portfolio. The vendor's federal footprint is fundamentally product-centric and production-oriented rather than labor-services-based.
