Ems Development Corporation

Ems Development Corporation, doing business as Ultra Electronics, Ems, manufactures specialized electronic components and assemblies for the Department of Defense as a prime contractor, with 93% of recent awards under prime vehicles and concentrated exposure to naval supply, ship construction, and electromagnetic systems. The company is headquartered in Yaphank, New York, and operates as a child entity within the Ultra Electronics Group (parent: Undersea Sensor Systems Inc.).

Ems Development Corporation competes predominantly full-and-open, with no SBA set-aside designations across its recent prime award footprint. The company's capability portfolio centers on radio frequency filters, circuit card assemblies, magnetometers, power supplies, capacitors, transformers, degaussing system components, and custom electronic assemblies—goods and services grounded in NAICS categories spanning capacitor and inductor manufacturing (115 awards), bare printed circuit board manufacturing (114 awards), and other electronic component manufacturing (75 awards). Concrete recent work includes a $3.92 million definitive contract from Naval Supply Systems Command for 135 outboard magnetometers (NSN 1H-5930-016443687, awarded March 27, 2025, completion April 26, 2027), a $3.6 million definitive contract for amplifier assembly from Naval Supply Systems Command (awarded September 10, 2024, completion September 20, 2027), a $1.93 million power amplifier DWR purchase order from Naval Supply Systems Command (awarded July 25, 2025, completion June 15, 2027), and a $606 thousand circuit card assembly purchase order from Defense Logistics Agency Land and Maritime (awarded February 4, 2026, completion February 3, 2027).

Customer concentration is heavily skewed to Navy and DLA programs. The top five funding agencies account for 89% of awards: Naval Supply Systems Command leads by potential value at 264 awards totaling $45.3 million combined potential, followed by Naval Sea Systems Command (101 awards, $13.9 million), Defense Logistics Agency Land and Maritime (282 awards, $10 million), Military Sealift Command (132 awards, $5.3 million), and Department of the Navy general (128 awards, $189 thousand). The two rankings diverge on volume versus dollars—DLA Land and Maritime places the most individual purchase orders but anchors fewer dollars per award, while Naval Supply Systems Command concentrates largest-dollar definitive contracts and delivery orders. Over 1,014 total awards spanning the past forty years, activity has grown sharply year over year, from 46 awards in 2023 to 49 in 2024 and 105 in 2025, with 54 awards in 2026 year-to-date. Eighty-two awards carrying combined potential value of $19.7 million reach ultimate completion within the next twenty-four months, presenting recompete exposure.

Ems Development Corporation places work under several indefinite delivery vehicles: Indefinite Delivery Contract N6092184C0006 hosts 19 task orders, Indefinite Delivery Contract N6133983C0056 hosts 10, and Indefinite Delivery Contract N6449819D4021 hosts 6 task orders (combined potential value $550 thousand). The vendor also references a prior single-award indefinite delivery contract with Defense Logistics Agency Land and Maritime valued at $250,000 for radio frequency filters.

In its 7% subcontractor footprint, Ems Development Corporation supplies degaussing equipment, electronic components, and specialized assemblies to major prime contractors including Huntington Ingalls Incorporated (LHA 10 advance procurement, DDG construction, CVN RCOH work, DDG modernization), National Steel and Shipbuilding Company (T-AO 205 detail design and construction), Marinette Marine Corporation (FFG(X) guided missile frigate detail design and construction), Electric Boat Corporation (SSN long lead time material), General Dynamics Land Systems Inc. (M1A2 Abrams tank production), and Raytheon Company (Patriot PBL capacitor supply). These sub-relationships span naval surface combatants, amphibious and auxiliary vessels, submarine programs, and land combat platforms.

The vendor's award portfolio reveals activity concentrated in naval propulsion, communications, power distribution, electromagnetic signature management (degaussing), and ship-mounted electronics—sectors where obsolescence engineering, custom magnetometers, and degaussing system components command highest dollar value. Combined dollars obligated ($185 million) exceed combined potential value ($75.9 million) by 244%, indicating substantial invoice activity against older awards and recurring low-dollar purchase order volume.
