Cornerturn LLC

Cornerturn LLC, a small business manufacturer and research and development services provider based in Corona, California, operates as a prime contractor on defense-focused purchase orders and delivery orders with the Department of the Navy, competing predominantly full-and-open across multiple naval commands. The company is a for-profit limited liability partnership with a track record of supplying specialized defense components—GPS receivers, battery cells, fiber optic cables, and software updates—and non-recurring engineering services to Naval Air Systems Command, Naval Information Warfare Systems Command, Naval Sea Systems Command, and Naval Supply Systems Command since its federal registration in 2004.

Cornerturn's prime work (75% of recent awards) spans both full-and-open and total small business set-aside purchase orders. Recent representative awards include a $431.3 million definitive contract from Naval Supply Systems Command for battery cells with an October 2026 completion date, a $1.6 million cost-plus-fixed-fee delivery order from Naval Air Systems Command for non-recurring engineering services on helicopter platforms, a $379.4 million delivery order for Advanced Logistics Flight Support Technical and Handling Data System work on the UH-60M Black Hawk program through the Naval Air Warfare Center, a $59 thousand total small business set-aside purchase order from Naval Information Warfare Systems Command for foal cables and assembly, and a $25.8 thousand total small business set-aside purchase order from Naval Information Warfare Systems Command for a Foal Receiver V2 GPS component. The company has consistently delivered components for the MH-60R Multi-Mission Helicopter and UH-60M Black Hawk platforms. Cornerturn holds two indefinite delivery vehicles: a single-award Basic Ordering Agreement with Naval Air Systems Command expiring in April 2027 and a SEAPORT-NXG multiple award contract with Naval Sea Systems Command extending through January 2029, which together anchor the majority of task-order work.

Customer concentration is pronounced within naval commands. The top five funding entities account for 85% of awards, led by Naval Air Warfare Center (13 awards, $9.5 million combined potential value) and Naval Information Warfare Systems Command (12 awards, $204 thousand combined potential value), followed by Naval Air Systems Command (7 awards, $8.5 million), Naval Sea Systems Command (6 awards, $103 thousand), and Naval Supply Systems Command (6 awards, $716 thousand). The gap between award count and dollar rankings reflects the small-dollar, high-volume profile of purchase orders for components versus the larger delivery orders for engineering services. Activity accelerated from three awards in 2022 to twelve in 2024, though the pace moderated to six awards in 2025 with one award issued in early 2026. Only three awards face completion within the next twenty-four months, with combined potential value of $626 thousand, creating minimal recompete pressure in the near term.

In its subcontractor role, Cornerturn supplies engineering integration and assembly support to Lockheed Martin on multiple integrated common processor build efforts, acoustic processor laboratory trainer modifications to CAE USA, production engineering services to Johns Hopkins University Applied Physics Laboratory, and system development trainer work to J.F. Taylor, among other primes. Across prime and sub engagements, Cornerturn's capability concentration aligns with engineering services, research and development in physical and engineering sciences, navigation and guidance system manufacturing, and battery component manufacturing, with the top procured items spanning rechargeable batteries, digital network products, and electronic countermeasures equipment.
