About the company
Ems Development Corporation, doing business as Ultra Electronics, Ems, manufactures specialized electronic components and assemblies for the Department of Defense as a prime contractor (93% of recent awards) and subcontractor, with a subsidiary footprint within the Ultra Electronics Group. The company operates from Yaphank, New York, competing full-and-open across defense procurement with no SBA set-aside certifications. Core capability spans radio frequency filters, circuit card assemblies, magnetometers, power supplies, capacitors, degaussing system components, and custom electronic assemblies under NAICS 334419 (Other Electronic Component Manufacturing) and related electronics manufacturing categories.
Ems Development competes predominantly against unrestricted defense procurement. Customer concentration is acute and navy-heavy: Naval Supply Systems Command anchors the relationship with 278 awards worth $57.5 million in combined potential value, followed by Naval Sea Systems Command (101 awards, $13.9 million), Defense Logistics Agency Land and Maritime (296 awards, $11 million), and Military Sealift Command (132 awards, $5.3 million). The top five named agencies account for 90% of award count. This top-heavy concentration skews toward the Navy and its supply infrastructure; Naval Supply Systems Command dominates dollars while Defense Logistics Agency Land and Maritime leads award count but carries smaller individual order sizes.
Representative prime work includes a $9.3 million June 2026 definitive contract from Naval Supply Systems Command for outboard magnetometer procurement (135 units, NSN 1H-5930-016443687, completion January 2029), a $3.92 million March 2025 magnetometer definitive contract with the same agency (135 units, same NSN, completion April 2027, indicating a recompete cycle), a $1.93 million July 2025 power amplifier DWR definitive contract with Naval Supply Systems Command (completion June 2027), and recurring Defense Logistics Agency Land and Maritime purchase orders for radio frequency filters, capacitors, and circuit card assemblies in the $20 thousand to $600 thousand range. Ems also performs obsolescence engineering services and ship repair work; Naval Sea Systems Command issued $118.5 thousand and $64 thousand purchase orders (August 2025) for obsolescence engineering, and Military Sealift Command awards include degaussing system components for named supply ships (USNS Robert E. Peary, USNS Chambers, USNS Earl Warren, USNS Charles Drew, USNS John Lewis) and advanced electronics work on T-AKE-class vessels.
Vehicle position centers on Naval Supply Systems Command single-award and multiple-award indefinite delivery contracts. The top parent vehicles include IDC N6092184C0006 (19 task orders), N6133983C0056 (10 task orders), N6449819D4021 (6 task orders, $550 thousand combined value), and others. A $250 thousand DLA Land and Maritime IDC for radio frequency filters is referenced across multiple summaries, indicating a high-velocity delivery-order posture under that vehicle.
Activity has grown substantially: 69 awards in 2022 to 106 in 2025, with 83 awards year-to-date in 2026. Recompete exposure is material: 89 awards (combined potential value $22.8 million) reach ultimate completion in the next twenty-four months. Combined dollars obligated ($199 million) exceed combined potential value ($89.1 million) at 223%, indicating invoiced revenue on completed contracts substantially exceeds remaining ceiling value across the active portfolio.
Ems subcontracts to major defense primes on ship construction and modernization. Named primes include Huntington Ingalls Incorporated (DDG 51, DDG 1000/1002 programs; LSD 46, LHD 4 restoration), National Steel and Shipbuilding Company (T-AO 205 detail design and construction), Marinette Marine Corporation (FFG(X) guided missile frigate), Electric Boat Corporation (SSN 814/815 long lead material), General Dynamics Land Systems (M1A2 SEPV3 Abrams production for Poland), and others. Subcontract scope spans degaussing equipment, display assemblies, switchboards, power supplies, shaft grounding systems, and electronic components for vessel propulsion and control systems.
Ems is a child entity within the Ultra Electronics Group, a parent corporation (UEI MQBGZ7HNRBG9) that also holds federal awards as Undersea Sensor Systems Inc., doing business as Ultra Electronics, Flightline Systems. The parent operates across 18 distinct customer agencies with 1,045 total awards (source span 1981–2026) and $199 million in obligated value. Ems represents the electronics manufacturing arm of that portfolio, with particular depth in naval vessel component supply.
