This article looks at the 10 worst performing defense stocks so far in 2025.

US defense stocks have wobbled this year, amid concerns about government budget cuts. In February, President Trump hinted at significantly reducing future military spending if things settle down with China and Russia. The creation of DOGE has also reshaped investors’ views of the industry.

Elsewhere, particularly in Europe, stocks have soared this year, with governments unlocking billions to supercharge their militaries. EU leaders met in Brussels in March to discuss the ‘ReArm Europe Plan’, which will allow the bloc to mobilize funds up to $860 million through bonds and relaxed rules on borrowing and spending.

Despite a shaky start to 2025, analysts at UBS are hopeful about America’s defense sector and believe the downside is shrinking and the FY26 budget request would present a better visibility into long-term expenditure plans. Here is what the firm recently stated:

“Consensus estimates have moved higher since the election despite the 40% sell-off. The downside potential seems increasingly smaller. We believe that the current environment is markedly different from Sequestration and do not believe a similar outcome is likely.”

Citi analyst Jason Gursky is also urging investors that this is the right time to buy American defense stocks.

“We recognize the world order is evolving under the current President, perhaps to a multi-polar one in which three countries control spheres of influence over the Americas, Europe and Asia. However, we don’t view that world to be any less dangerous or one that decreases the need to acquire the tools of deterrence.”

Gursky argues that as long as the global threat environment remains and the United States maintains its leadership role, regardless of whether it is as a sole superpower or as a power in a multipolar world order, defense spending is expected to remain robust, which would benefit stocks in the sector.

Two recent developments have reinvigorated investor sentiment. On March 21, Trump unveiled a new next-generation fighter jet, the F-47, to replace the F-22 Raptor. The jet will have stealth and penetration capabilities that exceed those of the current fleet. The initial contract to proceed with the production is expected to cost approximately $20 billion.

Earlier in the month, the US President also announced to resurrect America’s military and commercial shipbuilding industry, which he sees as vital to national security, given the strategic competition with China.

With that said, let’s now head over to the list of the worst performing defense stocks in 2025.

10 Worst Performing Defense Stocks So Far in 2025

10. Draganfly Inc. (NASDAQ:DPRO)

YTD Decline in Share Price: -23.69%

Draganfly Inc. (NASDAQ:DPRO) develops cutting-edge unmanned and remote data collection and analysis platforms and systems. It is one of the worst performing stocks in 2025, with a 23.69% decline in its share price this year.

During its Q4 2024 earnings call, Draganfly Inc. (NASDAQ:DPRO) reported a modest increase of 0.1% in its revenue for FY24 as its capacity to meet military and public safety demand did not come to full stream until late Q3. Gross profit also decreased by 32.3% from the prior year. The gross margin stood at 21.3%, compared to 31.5% in 2023.

Draganfly Inc. (NASDAQ:DPRO) recorded a net loss of $14.06 million for the full year. While this was an improvement from last year, the company is not expected to achieve profitability until 2026. Cash used in operating activities was down 37% year over year. It ended the year with a cash balance of a little over $6.25 million.

The company has recently appointed former Acting U.S. Secretary of Defense, Chris Miller, to its Board of Directors. As a seasoned national security expert, Miller is expected to guide Draganfly Inc. (NASDAQ:DPRO)’s strategic initiatives in the government and defense sectors.

In March, the company also announced the opening of its new facility in Tampa, Florida, to strengthen national security and defense partnerships. It is strategically located close to major government and military clients and includes a live fire testing facility.

9. Safe Pro Group Inc. (NASDAQ:SPAI)

YTD Decline in Share Price: -24.07%

In February, Safe Pro Group Inc. (NASDAQ:SPAI) signed a multi-year agreement with a leading technical university in Ukraine, under which the two organizations will collaborate on utilizing SPAI’s AI-powered drone image processing technology to develop training programs and build enhanced demining methodologies.

Despite these positive developments, shares are down by over 24% year-to-date, landing it a place among the worst performing stocks this year. Safe Pro Group Inc. (NASDAQ:SPAI) has had volatile returns since its IPO in August 2024, likely due to sharp market reactions to news related to the stock.

Another reason behind the stock’s volatility could be a lack of analyst coverage, which is resulting in low investor recognition. The general uncertainty in the aerospace and defense industry is also adversely impacting the returns of several companies in the sector.

8. Nauticus Robotics, Inc. (NASDAQ:KITT)

YTD Decline in Share Price: -31.61%

Nauticus Robotics, Inc. (NASDAQ:KITT) develops autonomous robots for the ocean industry. The company is also a key player in the defense sector. With a year-to-date dip of nearly 32% in its share price, KITT is among the worst performing stocks in 2025.

In January this year, Nauticus Robotics, Inc. (NASDAQ:KITT) forged a strategic alliance with Leidos to advance subsea autonomy solutions. This builds on a successful past collaboration between the two organizations, which was well-received by their mutual customer.

On March 20, Nauticus Robotics, Inc. (NASDAQ:KITT) announced an earlier-than-scheduled closure of its acquisition of SeaTrepid International, LLC, a company that provides subsea robotic services. The strategic acquisition is likely to result in significant revenue growth for the company in the fiscal 2025.

Nauticus Robotics, Inc. (NASDAQ:KITT) has been under pressure over the last several months to comply with NASDAQ’s listing requirements, which it regained in late February. However, the stock price has been declining over the past week and risks falling below the $1 mark again.

The company is also facing significant financial challenges. During the third quarter of fiscal year 2024, Nauticus Robotics, Inc.

In January, the company expanded into defense with a $925 million acquisition of drone maker, Edge Autonomy. On March 21, Redwire Corporation (NYSE:RDW) announced that it had received all regulatory approvals to complete its acquisition. The transaction is expected to expand the company’s portfolio to include combat-proven autonomous airborne platforms for critical national security needs.

However, Redwire Corporation (NYSE:RDW) has been under pressure due to ongoing investigations around the fairness of the Edge Autonomy acquisition to shareholders.
