Mesotech International, Inc.

Mesotech International, Inc., a for-profit manufacturer of meteorological and industrial monitoring systems based in Rancho Cordova, California, sells fixed base weather observing systems (FBWS), spare parts, site surveys, and contractor logistics support to the Department of Defense as a prime contractor across nearly every recent award, competing predominantly under small business set-aside vehicles and full-and-open delivery orders.

Mesotech's customer base concentrates heavily on Air Force commands. The top five customer organizations account for 84% of recent awards by count and 89% by combined potential value, led by the Department of the Air Force itself (114 awards, $148.6 million combined potential value), the Air Force Materiel Command Electronic Systems Center (117 awards, $47.3 million), and the Air Force Materiel Command Lifecycle Management Center at Hanscom Air Force Base (14 awards, $63.2 million). The Navy Information Warfare Systems Command placed fourteen awards ($777 thousand combined potential value), and a single $8.2 thousand purchase order came from Naval Information Warfare Systems Command for UHF modem kits in May 2024; aside from that and a $77.8 thousand FAA purchase order for Navigation Aids Systems assets in July 2023, Mesotech's federal footprint is almost entirely Air Force and Army. The Army Contracting Command at Redstone Arsenal holds a small but sustained relationship for weather station antennas supporting the Terminal High Altitude Area Defense (THAAD) system at Letterkenny Army Depot.

Mesotech holds two prime IDVs anchoring its portfolio. The primary vehicle is a $35.8 million single-award small-business-set-aside indefinite delivery contract (FA233023DB001) with the Air Force, awarded August 25, 2023, and running through August 2027, under which 43 task orders totaling $24.9 million in combined potential value have been issued for FBWS procurement, spare parts, site surveys, Enhanced Sensor Collection Appliance (ESCA) units, lightning sensors, laptop technical refresh, pressure port modifications, and contractor logistics support (help desk, repairs, warranties). Place of performance spans Hanscom Air Force Base, Massachusetts, and subordinate work at Camp Shelby, Djibouti, Kuwait, and Korea. A second, older $35.8 million single-award IDV (FA873018D0013) with no set-aside generated 74 task orders ($73.2 million combined potential value), and a $17.4 million single-award IDV (FA873020D0003) for FMQ-23 Fixed Base Weather Observing System equipment and services generated 51 task orders ($10.3 million combined potential value). A smaller $168.6 thousand single-award IDV with Army Contracting Command Redstone (awarded November 2021, running through November 2026) for THAAD weather station antennas has generated four delivery orders totaling $130.8 thousand.

Representative prime work illustrates the scope. A $4.9 million delivery order (June 2024) covered Quonset Point installation activities and lightning sensors under the primary Air Force IDV (FA233023DB001). A $3.1 million delivery order (September 2025) was issued without set-aside for general FBWS equipment and services. A $3.06 million delivery order (September 2024) provided contractor logistics support including help desk, spares, repairs, and warranties. A $1.97 million delivery order (December 2024) procured lightning sensors and mounting kits for consolidation B-tables. A $1.6 million delivery order (September 2025) covered fixed-base weather system and expeditionary meteorological sensor work performed with the University of Maine. A $1.2 million delivery order (January 2026) provided software updates, site surveys, and USAFA VM services at Hanscom Air Force Base. Delivery orders span firm fixed price, cost-no-fee, and cost structures; small business set-aside and full-and-open competitions; and air base locations from Alaska (Eareckson Site, Joint Base Elmendorf-Richardson) to overseas (Djibouti, Kuwait, Korea).

Activity has been consistent year over year across the lookback window, with 30 awards in 2022, declining to 18 in 2023, rising to 20 in 2024 and 22 in 2025, with 6 awards recorded in 2026 (partial year). Only 7 awards with combined potential value of $8 million face ultimate completion inside the next twenty-four months and therefore present recompete exposure. Mesotech's sub footprint is minimal — two sub-awards to Raytheon Company dated October 2025 and January 2025, both for environmental test equipment (shock, etc.) supporting KSA FMS THAAD and GAN TRIMMS programs — reflecting a prime-focused business model.

The vendor's capability portfolio is narrow and deep: Mesotech manufactures and sustains the FMQ-23 and related fixed-base weather observing systems, with NAICS concentration in Other Measuring and Controlling Device Manufacturing (132 awards) and Other Electronic and Precision Equipment Repair and Maintenance (86 awards), and PSC concentration in Meteorological Instruments and Apparatus (135 awards) and Maintenance/Repair/Rebuild of Measuring Tools (92 awards). The company has been registered in SAM since November 2001 and maintains small business status across most of its prime IDV work.
