About the company
RDF Corporation, a woman-owned small disadvantaged business manufacturer based in Hudson, New Hampshire, supplies high-reliability temperature and heat flux sensors—including RTD probes, thermocouples, temperature indicators, and ambient temperature sensors—to the Department of Defense and civilian federal agencies as a prime contractor (91% of recent awards) and as a subcontractor to major defense primes.
RDF's customer base is heavily concentrated in defense logistics and naval supply. The Defense Logistics Agency Aviation dominates the prime portfolio at 299 awards totaling $11.1 million in combined potential value; the Naval Supply Systems Command follows with 54 awards worth $2 million. Together, these two customers account for 63% of all prime awards and roughly 87% of combined potential value across RDF's footprint. Smaller but sustained volume flows from the Defense Contract Management Agency ($740 thousand across three awards), DLA Land and Maritime ($478 thousand across 28 awards), and DLA general procurement ($353 thousand across 49 awards). RDF has worked with 28 distinct customer agencies, including NASA Marshall Space Flight Center and the Air Force Research Laboratory, but DoD logistics and naval supply dominate the revenue picture.
RDF's prime contract work is entirely order-based, flowing through single-award Indefinite Delivery Contracts with DLA Aviation rather than governmentwide vehicles or BPAs. Two active IDCs anchor the portfolio: a $928.2 million ceiling single-award contract awarded June 11, 2026 (with two delivery orders already issued for $115.7 thousand and $182.5 thousand as of June 2026) and a $475.6 thousand small-business set-aside IDC running through July 2025. Recent delivery orders and purchase orders span $11 thousand to $447.3 thousand in individual transaction size, with the largest awards concentrated in ambient temperature sensors and RTD assemblies for military aircraft readiness. The combined potential value of awards completing within the next twenty-four months totals only $298 thousand—minimal recompete cliff exposure relative to the active ceiling base.
In its subcontractor role, RDF supplies temperature sensors and transmitter components to The Boeing Company on Space Launch System and Ares I upper-stage programs, to Lockheed Martin on F-35 and other advanced aircraft platforms, to Huntington Ingalls on Littoral Combat Ship and amphibious programs, and to Northrop Grumman, Raytheon, Electric Boat, Hamilton Sundstrand, and Kato Engineering on aerospace and naval applications. Sub-award activity has grown from a handful of awards annually to 18 awards in 2025, reflecting widening integration into prime contractor supply chains for thermal instrumentation across spacecraft, fighter jets, and naval vessels.
RDF's category footprint is narrow and specialized: 408 of 557 total awards (73%) fall under PSC 6685 (Pressure, Temperature, and Humidity Measuring and Controlling Instruments), with the remainder split among resistors, miscellaneous sensors and alarm systems, and transformer equipment. By NAICS, 151 awards classify under Other Measuring and Controlling Device Manufacturing (NAICS 334519), and 133 under Automatic Environmental Control Manufacturing (NAICS 333415). No set-aside category dominates the prime base; RDF holds SBA small-disadvantaged-business and woman-owned certification but competes predominantly in full-and-open and small-business set-aside solicitations without reliance on 8(a) or HUBZone vehicles. The vendor's competitive posture centers on qualified-products-list eligibility, established supplier relationships with DLA and NAVSUP, and sole-source or limited-competition status on specialized high-reliability sensors for mission-critical aerospace and naval systems.
