Grimes Aerospace Company

Grimes Aerospace Company, doing business as Honeywell, manufactures aircraft lighting systems, optical components, and high-precision aerospace assemblies for military aviation platforms as a prime contractor under multiple indefinite delivery contracts with the Defense Logistics Agency and U.S. Army Aviation and Missile Command. The company operates from Urbana, Ohio as a child entity of Honeywell Aerospace US LLC and competes on a full-and-open basis without set-aside designations, reflecting its status as an established large manufacturer in the aerospace industrial base.

Grimes Aerospace supplies searchlights, navigational lights, landing lights, recognition lights, light lenses, lamp assemblies, electrical connectors, housing assemblies, transformers, electric motors, gears, and related electronic and mechanical components across military rotary and fixed-wing platforms including the UH-60 Blackhawk, C-130 Hercules, CH-47F Chinook, F-15 Eagle, F/A-18 Super Hornet, B-52 Stratofortress, C-5 Galaxy, E-3 AWACS, P-3 Orion, and H-53 Sea Stallion. Representative prime work includes a $4.5 million single-award indefinite delivery contract from the Army Aviation and Missile Command (awarded May 28, 2026, through May 28, 2031) for overhaul of light landing aircraft components supporting CH-47F Block II modernization, with an initial $338,502 delivery order; a $245,412 delivery order from DoD Aviation for aircraft lighting and recognition systems (June 24, 2026); and a $202,200 delivery order from DLA Aviation for aircraft taxiing lights (January 28, 2026, with completion through August 2029).

The vendor's customer base concentrates heavily on Defense Logistics Agency Aviation, which accounts for 5,364 awards representing $850.8 million in combined potential value (about 76% of the documented portfolio). The Army Aviation and Missile Command ranks second with 90 awards and $137.5 million in combined potential value. Five named customer agencies account for 93% of recent awards. A notable tension between volume and dollars exists: DLA Aviation dominates both metrics by an overwhelming margin, while Army Aviation and Missile Command places far fewer orders but anchors them with higher unit values, particularly on the landing-light overhaul IDV.

Grimes Aerospace holds position on five named indefinite delivery vehicles. The largest by task-order volume is Indefinite Delivery Contract SPM7AX07D9001 (1,423 task orders, $29.9 million combined potential value), followed by SPE4AX15D9411 (1,348 task orders, $50.1 million), SPE4AX23D0003 (1,126 task orders, $32.6 million), SPM4AX07D0004 (114 task orders, $965 thousand), and SPM74005D9743 (63 task orders, $375 thousand). These DLA Aviation vehicles represent the backbone of the vendor's recurring revenue stream, with delivery orders issued against them for components across the full spectrum of aircraft lighting and associated assemblies.

Recent activity has declined: the vendor received 397 awards in 2022, 390 in 2023, 446 in 2024, 356 in 2025, and 90 through mid-2026. This downward trajectory, alongside a recompete cliff showing 152 awards (combined potential value $11 million) completing within the next twenty-four months, represents a material risk exposure. The combined potential value across the full documented portfolio is $1.12 billion, with $314.2 million obligated (28% realization rate), a pattern consistent with task-order vehicles where many orders are issued at ceiling values but not fully funded.

Grimes Aerospace subcontracts to The Boeing Company and Bell Boeing Joint Project Office on programs including Apache AH-64E Foreign Military Sale helicopters, CH-47F Block II production for Germany with air-to-air refueling, F-15 development systems, C-17 material support, and CMV-22 production long-lead items. These relationships position Grimes as a Tier-2 component supplier within Boeing's helicopter and fighter programs rather than as a prime integrator.

The vendor's award portfolio spans three dominant NAICS categories — Other Aircraft Parts and Auxiliary Equipment Manufacturing (1,732 awards), Mechanical Power Transmission Equipment Manufacturing (1,443 awards), and Vehicular Lighting Equipment Manufacturing (1,393 awards) — with the Electric Vehicular Lights and Fixtures PSC code accounting for 3,959 of the documented 7,745 total awards. This extreme concentration reflects Grimes' specialization in aviation lighting as both a core capability and a dominant revenue driver. The recent activity decline and substantial recompete exposure in the next two years, combined with heavy reliance on a single customer (DLA Aviation) and a single product category (aircraft lighting), signal potential revenue headwinds absent successful recompete outcomes or new customer acquisition.
