Defense Stocks Worth Buying Under $15

Defense spending is one of the few corners of the market where political tailwinds line up across both parties heading into mid-2026, and small-cap names trading under $15 give retail investors leverage to that theme without chasing mega-cap primes at premium multiples. Drone, satellite, and autonomous systems suppliers are pulling in real contracts from the Pentagon, NATO, and allied governments, yet many still trade like speculative startups. That gap between contract momentum and share price is worth a closer look.

Here are three defense-adjacent stocks trading under $15 that look compelling in today’s political climate.

Red Cat Holdings (NASDAQ: RCAT)

Red Cat Holdings (NASDAQ:RCAT) builds American-made tactical drones and uncrewed surface vessels for the U.S. military and allied governments under the Black Widow, FANG, Teal, FlightWave, and Blue Ops brands.

Shares entered May comfortably under the $15 ceiling after a 7.57% pullback over the past month that gives new buyers a more reasonable entry. Year to date the stock is up 41.61%, and over the past year it has gained 121.5%. Fiscal Q4 2025 revenue hit $26.235 million, up 1,509.8% year over year, with EPS of -$0.17 against a -$0.15 consensus.

The bull case is straightforward: the first NSPA order for 100 Black Widow drones, fresh orders from a second Asia-Pacific ally, and a 520% expansion of manufacturing capacity to 254,000 square feet position Red Cat as a scaled domestic supplier into surging allied demand. CEO Jeff Thompson called 2025 “a transformative year” with 161% revenue growth. The risk is profitability: 4.2% gross margins and -$89.1 million in operating cash flow mean execution must keep pace with the order book. For investors who can stomach the burn, RCAT looks like a credible play on American tactical drones.

Redwire (NYSE: RDW)

Redwire (NYSE:RDW) is a multi-domain space and defense technology company spanning satellite platforms, in-space manufacturing, and uncrewed aerial systems following the June 2025 Edge Autonomy acquisition.

The stock entered the month of May up 22.89% year to date. Q4 2025 revenue came in at $108.79 million, up 56.4% year over year, with a record $411.25 million backlog and a 1.52 book-to-bill. Management guided 2026 revenue to $450 million to $500 million, with roughly $17 million in annualized interest savings from refinancing.

The bull case combines a $44 million Phase 2 DARPA Otter contract for the SabreSat VLEO platform, Stalker UAS sales to the U.S. Army and an undisclosed European NATO ally, and Penguin deliveries to Ukrainian Armed Forces. CEO Peter Cannito said Redwire is “entering 2026 with strong momentum.” The risk is the $621.8 million accumulated deficit and ongoing EAC adjustments on development programs that have squeezed margins. With backlog at record highs and guidance pointing to a step-change in 2026 revenue, RDW looks like a credible play for investors hunting space and UAS exposure.

Satellogic (NASDAQ: SATL)

Satellogic (NASDAQ:SATL) operates a constellation of high-resolution Earth observation satellites and sells imagery and geospatial analytics to defense, intelligence, and sovereign government customers.

Shares are garnering lots of attention in 2026 after a remarkable 283.96% year-to-date run, leaving plenty of room under the $15 ceiling. Q4 2025 revenue was $6.2 million, up 105.3% year over year, and the company posted net income of $30.5 million, swinging from a $70.9 million loss a year earlier. Cost of sales fell to 20% of revenue from 39%, a meaningful operating-leverage signal.

The bull case rests on the Merlin constellation, fully funded by a $30 million customer contract, with first satellites targeted for launch in October 2026 to remap the planet daily at 1-meter resolution. Sovereign deals with Portugal, Albania, Australia, and Malaysia, plus a $94.43 million cash position, give Satellogic runway. The risk is concentration: lengthy sales cycles, dependence on SpaceX for launches, and the chance of losing one large customer. As a defense-first geospatial pure-play, SATL is the most speculative of this trio but offers the most asymmetric upside if Merlin hits its window.

A share price under $15 is only a starting filter. These three names each carry real losses, real customer concentration, and real execution risk alongside their contract wins. Investors should size positions accordingly and conduct their own diligence before treating any as a buy.
