Tariffs on drones and aerospace gear are no longer just policy headlines. They are now a live reshuffle of supply chains and profit pools that could reward some companies and pressure others. As import costs climb and onshoring support kicks in, investors who understand where production and capabilities sit may see opportunities that others miss. This article walks through 3 U.S. stocks exposed to these tariff shifts and explains why they are on the radar now.

The three stocks in this article are just a starting sample from this onshoring theme, and the full screen surfaced 30 more U.S. companies with similar drone and aerospace angles that are not covered below. To see that wider field and start sorting potential high conviction ideas for yourself, head straight into the U.S. Onshoring of Drone and Aerospace Manufacturing screener.

Viavi Solutions (VIAV)

Viavi Solutions is a US$9.3b communications test and optical technology company that supplies the kind of network, timing and sensing gear onshoring projects need to qualify drones, avionics and secure military links. Most revenue comes from its Network and Service Enablement segment at about US$1.2b, with Optical Security and Performance Products adding roughly US$335 million, which together span test equipment, software and highly engineered optical coatings used across government, aerospace, automotive and industrial markets.

Investors looking at the drone and aerospace onshoring story may find Viavi Solutions interesting because it already supplies test systems, inertial navigation modules and optical components into many of the defense and unmanned programs that could benefit from U.S. tariffs and incentives. The company is pushing deeper into AI data center optics and 6G test platforms, which broadens its opportunity set beyond defense, but it remains currently unprofitable and relies on higher risk external borrowing, with recent insider selling adding another caution flag. The trade off is a business tied directly to secure, high performance networks and mission critical aerospace communications at a time when both funding and regulation are reshaping where that work gets done.

Viavi Solutions looks like a pure play on secure test gear and optics for onshoring, yet its unprofitable status and reliance on external borrowing raise big questions. Get the full picture in the 2 key rewards and 2 important warning signs

Keysight Technologies (KEYS)

Keysight Technologies supplies the design software and test equipment that drone, avionics, and defense manufacturers rely on to prove their electronics work before anything leaves the factory floor. This links it directly to U.S. onshoring of drone and aerospace production. Its tools span wireless, data centers, aerospace and defense, automotive, semiconductors, and general electronics, and it also sells software, recurring services, and support that keep those systems running. With a market cap of about US$54.5b, Keysight is one of the larger pure test and measurement companies tied into this theme.

Investors watching the tariff driven reshaping of drone and aerospace supply chains may want Keysight Technologies on their radar because it supplies the RF and network test gear those new U.S. plants will need from design through to production. The company is leaning into AI data center, next generation wireless, and defense modernization work. These areas can support growth and margins, yet Keysight also faces higher tariff related costs and relies on external borrowing that could pressure returns if mitigation or pricing actions fall short. Valuation already reflects high expectations, and insider selling has picked up in recent months. The interest here is a strong test and software franchise tied to onshoring and AI, with enough risk around tariffs, capital intensity, and price to reward careful analysis.

Keysight Technologies is already plugged into AI data centers, defense modernization, and tariff fueled onshoring. The bigger question is how that mix lines up on growth, pricing power, and risk in the 4 key rewards and 1 important warning sign

Amprius Technologies (AMPX)

Amprius Technologies develops and sells silicon anode lithium ion batteries for mobility, with a strong focus on drones and aviation platforms that fit directly into the U.S. onshoring push for domestic drone and aerospace supply chains. The company generated about US$109 million from its Battery Business and has a market cap of roughly US$1.5b, which puts it firmly in the small to mid cap bracket for investors looking at specialized suppliers rather than broad industrial giants.

Amprius Technologies gives you exposure to the part of the drone and aerospace onshoring story that sits inside the airframe: the battery pack. Its silicon anode cells are already being used in high performance unmanned systems and electric aviation trials, and management is working on NDAA compliant U.S. manufacturing partnerships that could matter more as 100% tariffs on key imported drones and components arrive from 2026. The trade off is clear. You are looking at an unprofitable, capital hungry business that depends heavily on drone and aviation demand and has to prove it can scale production without eroding margins or leaning too hard on fresh equity. The detailed numbers and contract pipeline tell a more nuanced story than the headline battery hype.

Amprius Technologies is racing to supply batteries for high performance drones and aviation, yet the real story sits in the contracts, cash needs, and execution risk. Get the full full narrative for Amprius Technologies
