Mast Technologies, LLC

Mast Technologies, LLC, operating as Mast Distribution, is a San Diego-based for-profit limited liability company and manufacturer specializing in advanced materials, with a focus on rubber and microwave absorbing products for military applications. Registered in the System for Award Management since September 2009, the company has established itself as a trusted supplier of specialized technical materials to the U.S. Navy, providing mission-critical components that support naval operations, facility maintenance, and shipbuilding initiatives. The company's core expertise centers on engineered rubber tiles, radar absorbing materials, electromagnetic interference solutions, and RF absorbing materials designed to meet stringent military specifications and classified requirements.

Mast Technologies has delivered a substantial and consistent portfolio of federal contract awards, totaling approximately $20.2 million in prime contract value across multiple delivery orders and definitive contracts awarded by the Naval Supply Systems Command and Naval Sea Systems Command. The company's primary product offering consists of specialized rubber tiles, including radar absorbing material Type 3R tiles and tiles identified by various National Stock Numbers such as 1H-5840-014645007 and 1H-5840-015015592, which are engineered to withstand demanding shipboard environments including temperature fluctuations, humidity, salt spray, and UV exposure. Recent prime awards include a $5.78 million delivery order (June 2025), a $1.997 million definitive contract (December 2024), a $1.40 million purchase order (August 2025), and a $1.99 million definitive contract (April 2024), among numerous other awards spanning from 2021 through October 2025. All prime contract awards lack small business set-aside designations, reflecting the specialized and sole-source nature of Mast Technologies' manufacturing capabilities. In addition to prime contracting, Mast Technologies has served as a subcontractor to major defense prime contractors, including Huntington Ingalls Incorporated on multiple DDG-class destroyer construction programs (DDG-131, DDG-133, and DDG-135) and Lockheed Martin Corporation for RF absorber materials, demonstrating its role as a critical supplier within the broader defense industrial base. Manufacturing of these specialized materials is restricted to U.S. citizens, and Mast Technologies must maintain SECRET-level security clearance and access to classified specifications to perform these contracts.

Mast Technologies currently holds two active indefinite delivery contracts with the Naval Supply Systems Command. The primary and most recent IDC, awarded on June 18, 2025, carries a ceiling value of $31,728,760 and extends through June 19, 2030, providing the company with a five-year contract vehicle for the ongoing procurement of rubber tiles identified by National Stock Number 1H 5841-01-464-5293. This contract represents a significant expansion of the company's existing relationship with NAVSUP and reflects the strategic importance of Mast Technologies as a sole-source supplier. The second IDC, awarded on September 27, 2021, with a ceiling value of $5,327,914 and an expiration date of December 31, 2025, was awarded under the Defense Logistics Agency's Government-Wide Acquisition Contracts vehicle and similarly covers the provision of rubber tiles with National Stock Number 1H 5841-01-464-5293. This predecessor contract has generated numerous delivery orders and purchase orders throughout its performance period, with individual orders ranging from $219,200 to $5.78 million, demonstrating consistent demand for Mast Technologies' specialized products. Both IDCs are structured as single-award contracts with no small business set-aside designations, underscoring the Navy's reliance on Mast Technologies' unique manufacturing capabilities, engineering expertise, and engineering source approval status for these mission-critical materials supporting naval facilities maintenance, ship repair programs, and naval shipbuilding operations.
