What Sheergard does

Sheergard Composite Solutions Inc. is a full-service provider of radome and concealment solutions, designing and manufacturing RF-transparent composite structures that protect antenna systems from extreme environmental conditions while preserving electromagnetic transmission performance. The Salem, NH-headquartered company operates four core product lines: air-supported radomes (PTFE-coated fabric membranes, single-piece and band-agnostic across L through W bands up to 110+ GHz, sizes 4m to 70m+), sandwich composite radomes (rigid fiberglass skins with low-density foam cores, 3–5 GHz to Ka-band, sizes 3m to 24m), electromagnetic windows (flat panels with dielectric constants below 2.8, range -60°F to +400°F), and 5G mmWave shrouds (band-agnostic up to 100 GHz). Underlying technology rests on proprietary composite formulations (K6, K10OS, K60C, Q65C, M26) with permanent hydrophobic PTFE surfaces, validated through MIL-STD-810 environmental testing and independently verified durability (3.5-inch hail at 150 mph, wind ratings up to 250 mph, 20+ year service life). The company has direct lineage to Cornell Aeronautical Laboratory and Walter Bird's 1940s pioneering work, and was re-established in 2023 after Lotus Horizons Holdings acquired the SHEERGARD technical assets from Saint-Gobain's dissolved Composite Solutions business unit.

Sheergard generates revenue primarily through project-based sales of custom-engineered radome systems priced per customer specification, with multi-year contracts for high-value mission-critical deployments. Hardware sales are complemented by professional services revenue streams including worldwide installation, certified inspection and maintenance, RF design and analysis, and structural modeling using finite-element software. The customer base is split between two primary verticals: government and defense (SATCOM terminals, deep space surveillance, mission-critical ground stations, military radar, ATC) and commercial infrastructure (5G networks, weather radar, commercial SatCom, LEO Satcom ground terminals). Distribution is anchored by dedicated direct sales representatives covering specific product lines and geographies, supplemented by an OEM partnership with RF Industries for the TruField modular 5G radome line into wireless carriers and neutral host providers. Manufacturing is split between the Salem, NH headquarters (air-supported radomes and EM windows) and the Sheergard Utah joint venture facility in North Salt Lake (sandwich radomes), with Sheergard holding majority ownership in the JV.

The company holds AS9100D certification (since 2024), ITAR, EAR, DFARS, and FAR compliance, and qualifies as a small business under multiple NAICS codes. Boeing is the only explicitly named customer in the available sources. Recent strategic moves include the January 2026 formation of the Sheergard Utah joint venture with Whitehead Composite Industries to scale sandwich radome manufacturing, and the February 2025 strategic partnership with JRC Facilities to create a turnkey full-service provider for mission-critical sectors worldwide. Leadership comprises President Rajeev Singh, Vice President Casey Talbot, and Head of Installs and Operations Support Seth Steed, with the company majority-owned by Lotus Horizons Holdings.

Broad incumbents

• Thales: European aerospace and defense prime with radome and antenna protection capabilities across radar, air traffic management, and SATCOM. Comparable because it competes in the same mission-critical aerospace and defense markets, particularly in Europe where Sheergard's UK-based international sales coverage is targeted.
• Saint-Gobain: Former parent of the SHEERGARD radome business (divested in 2023) and a leading materials science company with PTFE, composites, and high-performance fabrics relevant to radome substrates. Comparable because it remains a potential supplier or competitor in advanced composite radome materials, even after divesting the radome business unit.
• General Dynamics Mission Systems: U.S. defense electronics and systems integrator that supplies antenna subsystems and associated protective structures. Comparable because it serves similar defense customers with mission-critical RF systems, though radomes are a smaller portion of its broader portfolio.
• Raytheon (RTX): Large aerospace and defense prime that supplies radomes as part of broader radar, missile, and SATCOM systems. Comparable because it competes for the same defense program dollars but offers radomes as one capability within a much wider portfolio rather than as a dedicated specialty.
• Lockheed Martin: Largest U.S. defense prime that integrates radomes into radar, missile, and SATCOM platforms. Comparable because it serves the same DoD mission-critical programs where Sheergard's radomes are deployed, but treats radomes as a sub-component of integrated weapons systems.
• Northrop Grumman: Aerospace and defense prime supplying antenna and radome subsystems across radar, surveillance, and space programs. Comparable because it is both a potential customer and competitor in the same mission-critical antenna protection space, but on a much larger portfolio scale.

Direct peers

• L3Harris Technologies: Large aerospace and defense prime with a dedicated antenna and radome product line serving radar, SATCOM, and electronic warfare applications. Comparable because it designs and manufactures both air-supported and rigid radomes for the same defense, aerospace, and mission-critical customer base that Sheergard serves.
• Communications & Power Industries (CPI): Manufactures radomes and antenna systems for ground-based, shipboard, and aerospace applications including SATCOM and radar. Comparable because it sells engineered radome solutions for similar defense and commercial telecommunications end markets and competes on similar RF performance specifications.
• Cobham Advanced Electronic Solutions: Aerospace and defense supplier of RF, microwave, and antenna protection systems including radomes for airborne, shipboard, and ground applications. Comparable because it delivers engineered radome solutions for the same defense and aerospace customer base and emphasizes environmental durability and RF transparency.
• Hensoldt: European defense electronics specialist with radome and antenna subsystems for radar, SATCOM, and electronic warfare platforms. Comparable because it serves the same mission-critical defense customers, emphasizes RF-transparent composite structures, and competes for similar program-of-record opportunities.
