Defense Electronics Manufacturing Faces Capacity Squeeze
Summary
FEIM and LPTH raised equity as defense programs shifted into production, exposing qualified capacity, detector lead times and customer-funded expansion as constraints.
On September 10, 2026, Frequency Electronics (FEIM) and LightPath Technologies (LPTH) both said that missile, counter-UAS, and satellite programs moving from qualification into rate production were generating orders faster than qualified component capacity could expand.[1][2]
Defense programs are moving to monthly production
Once a program enters rate production, the supplier's central problem becomes how many units it can deliver each month. Defense components usually pass through design, testing, and customer qualification before production. Development work follows milestones, while production requires recurring monthly deliveries. When a cohort of programs matures together, orders can arrive in steps and quickly consume available melting, testing, and assembly capacity.
LightPath makes infrared optical materials, lenses, and camera assemblies. It said two counter-UAS programs were moving to deliveries of tens of systems per month. Its internally produced infrared glass was the largest capacity constraint, while lead times for purchased detectors had increased from about six months to ten months or more.[2] After glass capacity improves, the constraint can move to detectors, motors, and magnets, so one expansion does not finish the job.
Two equity raises put capacity ahead of revenue
Both companies used outside equity to buy capacity before the related orders became revenue. LightPath completed a $50 million primary offering in June 2026 and ended the fiscal year with $93.2 million of cash to convert its $110.9 million backlog into revenue. It also expects fiscal 2027 capital spending to exceed fiscal 2026's $6.3 million.[2]
Frequency Electronics reversed course more sharply. In July, management said it did not need significant new investment to reach at least $150 million of fiscal 2029 revenue. Eight weeks later, it disclosed an approximately $73 million offering because customers wanted more output sooner.[1] One secure military communications contract covers more than 1,000 systems, and the customer requested a monthly production increase of more than 50%. The company also said some customers may pay for expansion, although it still rejects schedules it considers impossible.[1]
Qualified throughput is gaining bargaining power
Customers funding expansion indicates that qualified throughput, rather than low-priced capacity in general, is scarce. The first effects should appear in inventory, capital spending, and share count before the revenue ceiling changes. Suppliers that expand on time may also gain more freedom to select contracts and protect margins. Karman Holdings is investing ahead of orders and says its reported capital spending excludes customer-funded capital, showing similar behavior in another missile-component supplier.[3]
The conclusion does not apply to all defense electronics suppliers. Mercury Systems is also moving programs from development into production, but management described this as a natural progression rather than a constraint and expects capital spending to remain roughly flat.[4] Optex Systems (OPXS) reported only 3.8% first-half order growth and remained affected by a government shutdown and delayed appropriations. A capacity squeeze is most likely where programs have entered production and the supplier controls a scarce material or qualified process.
Companies exposed to the same production shift
- Karman Holdings (KRMN): The missile nozzle, shroud, and separation-motor supplier is investing ahead of orders, making its capacity path the closest parallel to the two directly reporting companies.
- Mercury Systems (MRCY): Its defense electronics programs are also moving into rate production, but current capacity is not a disclosed constraint, making it an important boundary case.
- Teledyne Technologies (TDY): Its infrared detectors sit at the type of second bottleneck LightPath described. Longer lead times may reach Teledyne's orders and capital spending first, although LightPath did not identify its supplier.

We've told you previously that we have sufficient capital in place to meet the minimum $150 million revenue target by fiscal 2029. Numerous customers, however, are asking us to do more for them and to do it more quickly. To meet this customer-driven business expansion, we decided to pursue a secondary offering of our common stock in July, which raised approximately $73 million
