Coastal Mechanics Company, Inc.

Coastal Mechanics Company, Inc., a Houston, Texas-based Subchapter S corporation, delivers precision mechanical components, fabrication, machining, and engineering services to the Department of Defense, NASA, and civilian federal agencies as a prime contractor on 374 awards valued at $1.38 billion. The company operates primarily through blanket purchase agreements and indefinite delivery contracts without relying on SBA set-asides for the majority of its prime work, though it maintains a small-business designation and carries a named subsidiary, Coastal Mechanics Technical Support & Services, LLC, a self-certified small disadvantaged business.

Coastal Mechanics' capability footprint spans precision machining, welding, fabrication, board fabrication and population, hydraulic component repair and overhaul, and specialized component manufacturing for military aircraft and naval systems. Recent representative work includes a $1 billion single-award BPA with Naval Sea Systems Command for machine shop services (awarded May 11, 2023, ceiling through April 30, 2026), a $918.4 million indefinite delivery contract with Army Aviation and Missile Command for AH-64 Apache pump maintenance and overhaul (awarded June 28, 2024, $146.8 thousand delivery order on the AH-64E Remanufacture program), a $7.4 million IDC with Naval Air Warfare Center for board fabrication and population services (awarded July 19, 2022, $2.152 thousand initial task order), and a $50 million multiple-award IDC with Naval Sea Systems Command for rapid machining assembly (awarded May 22, 2023, $500 delivery order). The company also holds a $4.999 million monthly BPA call vehicle with Naval Air Warfare Center for government purchase card services (total-small-business set-aside, recurring monthly awards from January 2023 through April 2026).

Customer concentration is dominated by the Navy. The top five agencies by combined potential value account for 98 percent of the portfolio: Naval Sea Systems Command leads at $1.1 billion (7 awards, anchored by the $1 billion machine shop BPA), followed by Naval Air Warfare Center at $209.1 million (39 awards), Naval Supply Systems Command at $26.4 million (11 awards), Army Materiel Command Contracting Command Detroit Arsenal at $14 million (59 awards, predominantly monthly BPA calls), and the Department of the Army at $7.6 million (17 awards). By award count, the portfolio splits differently—Defense Logistics Agency Aviation leads at 77 awards with only $1.2 million in potential value, a signal of high-frequency, low-dollar supply orders, while Army Contracting Command Redstone places 59 awards for $14 million, and Coast Guard holds 51 awards for $4.3 million.

Coastal Mechanics' vehicle holdings reflect deep Navy integration. The top parent vehicles are a series of Army Contracting Command Detroit Arsenal BPAs (W56HZV22AJ029 with 32 task orders and $12.9 million, W56HZV19AJ023 with 29 task orders and $5.7 million, and W56HZV16AJ022 with 20 task orders and $4.5 million), followed by Naval Air Warfare Center Indefinite Delivery Contract N6893619D0046 (19 task orders, $96.7 million, for advanced weapon products including machining, additive manufacturing, fabrication, and electronic and chemical components) and Naval Supply Systems Command BPA N6833523A0043 (12 task orders, $60 million, for metal valves, pipe fittings, and miscellaneous hardware under Federal Supply Classes 4730 and 5340).

Activity has contracted modestly. The company recorded 374 total prime awards across its tracked history, with an average of roughly 30 to 44 awards per year from 2022 through 2025, then dropping to 5 awards in 2026 year-to-date. This reflects the snapshot date of July 15, 2026, not a sustained decline. Only six awards face ultimate completion within the next twenty-four months, with combined potential value of $1.4 million, indicating limited recompete exposure in the immediate pipeline. The company's obligated dollars ($30.8 million) represent only 2 percent of combined potential value, a signal typical of indefinite delivery vehicles and blanket purchase agreements where ceiling values far exceed near-term invoicing.

The capability portfolio concentrates in Other Aircraft Parts and Auxiliary Equipment Manufacturing (88 awards), Machine Shops (51 awards), Other Support Activities for Air Transportation (43 awards), and Military Armored Vehicle and Tank Component Manufacturing (33 awards). Product and service codes align: Miscellaneous Vehicular Components (67 awards), Airframe Structural Components (29 awards), and Maintenance/Repair/Rebuild of Aircraft Components (19 awards). Representative work across vehicle types includes repair of MH-65 and MH-60T helicopter components for the Coast Guard (valve repair and accumulator overhaul), CH-47F Chinook hydraulic pump maintenance and overhaul for the Army, AH-64 Apache pump component manufacturing, spacecraft hardware fabrication for NASA Glenn and Langley research centers, and general machine-shop and rapid-prototype services across Navy shipbuilding programs. Coastal Mechanics competes predominantly full-and-open, avoiding small-business set-aside posturing on most vehicle work; a minority of orders on specific vehicles (Naval Air Warfare Center purchase-card BPAs, Letterkenny Army Depot BPA, NASA Glenn BPA) carry total-small-business or small-business set-aside designations.

Coastal Mechanics works with defense departments to build and supply one-off replacement parts for legacy systems.
