3 US Defense Tech Stocks Worth Watching After Nvidia China Export Scrutiny

AI security just collided with geopolitics. Nvidia’s leadership shock and fresh scrutiny on chip exports to China have thrown a spotlight on firms that sit closer to U.S. defense, surveillance, and secure semiconductor pipelines. That disruption creates both risk and potential openings for investors who care about how money and national security intersect. This article walks through 3 stocks exposed to this news and explains why each one may warrant a closer look at this time.

The three stocks covered below are just a sample, and the full screen surfaced 28 more U.S. defense and national-security technology contractors with equally compelling narratives that are not covered in this article. If you want to identify and analyze potential high-conviction ideas right now, head straight to the US Defense and National-Security Technology Contractors screener.

nLIGHT (LASR)

nLIGHT sits close to the screener’s core theme, with high power semiconductor and fiber lasers that are directly tied to U.S. aerospace, defense and secure sensing programs. The analyst consensus Narrative on Simply Wall St frames the potential size of that pipeline.

nLIGHT designs and manufactures semiconductor and fiber lasers for aerospace and defense, industrial and microfabrication customers, generating about US$220 million from Laser Products and roughly US$97 million from Advanced Development. The business carries a market value of about US$2.6b.

"The rapid growth and expanding pipeline in aerospace and defense, particularly around high power laser solutions such as HELSI 2 and DE M SHORAD, alongside newer awards like the Joint Laser Weapon System contract with a ceiling of roughly US$600 million to US$627 million, continues to position nLIGHT to capture a larger share of rising directed energy spend and support multi year revenue expansion."

What ultimately matters is how a single pressure on execution shapes the mix between high value defense work and the rest of nLIGHT’s business.

That mix is where the story gets interesting, and the full narrative for nLIGHT unpacks how nLIGHT’s defense pipeline, industrial demand, and execution risks could be decoupling beneath the surface.

Kopin (KOPN)

Kopin is firmly plugged into the screener’s defense and national-security focus because its microdisplays sit inside soldier sights, helmets, and sensor systems, and according to jack_LTH_stocks, an investor in the Simply Wall St Community, that defense positioning is now intersecting with drones and AI infrastructure.

"The company recently announced multiple prototype orders for its Sentinel FPV products from companies participating in the U.S. Government's Drone Dominance Program, with volume awards expected following programme evaluations."

What happens if a single large defense program decision shifts how quickly those early projects convert into higher margin, recurring hardware demand?

That conversion risk is exactly what full narrative for Kopin pulls apart, mapping how accelerating defense demand, commercial opportunities, and execution missteps could reshape Kopin’s next chapter.

LightPath Technologies (LPTH)

LightPath Technologies builds optical systems that sit close to the screener’s defense and surveillance theme, with a single optics segment generating about US$77 million in revenue and a market value near US$527 million anchoring it firmly in the listed national-security supply chain.

The analyst consensus Narrative on Simply Wall St sees LightPath Technologies as more than a parts supplier, positioning its optical know how as a way to plug deeper into defense, surveillance and secure sensing programs that demand trusted suppliers on U.S. soil.

"The acquisition of G5 Infrared is expected to be highly accretive and transformational, enabling LightPath Technologies to transition from a component manufacturer to a solutions and subsystem provider, potentially increasing revenue through expanded product offerings and larger contracts."

What investors really need to watch is how one quiet shift in where the highest margin work happens filters through future pricing power.

That pricing shift is exactly what the full narrative for LightPath Technologies unpacks, revealing how acquisition integration, margins and defense demand could be quietly accelerating the value story for LightPath Technologies.
