Other industry players, such as  General DynamicsGD and  Embraer EMBJ, have delivered a similar performance in the past six months. Shares of GD and EMBJ have gained 1.3% and 3.8%, respectively, in the said period.

RTX's stronger performance than the broader aerospace and defense industry, along with gains by key peers, may make the stock attractive to investors. However, it is important to assess whether RTX's strong fundamentals and growth prospects can support sustainable long-term gains. Evaluating the company's growth drivers, earnings outlook and key risks will be important for determining whether the stock has further upside.

Tailwinds for RTX

RTX continues to strengthen its aerospace and defense business through higher production capacity, major contract wins and advances in defense technology. In August 2026, RTX completed a 17,000-square-foot expansion of its Forest, MS, manufacturing facility, backed by a $50 million investment. The expansion will increase production capacity for electronic warfare and radar systems and is expected to create 100 high-skilled jobs by 2028.

RTX is also increasing production of Tomahawk cruise missiles following a $22.9 billion multi-year contract from the U.S. Navy. The contract supports plans to increase annual production to more than 1,000 Tomahawk missiles and related support. RTX is investing in its workforce, technology, supply chain and facilities to meet rising demand from the U.S. Navy and its allies.

In addition, RTX continues to develop new technologies for the F-35 program. In August 2026, RTX completed altitude testing of its next-generation Enhanced Power and Cooling System (EPACS). The system is designed to provide greater cooling capacity and support future upgrades, helping maintain the F-35's performance throughout its service life.

These developments highlight RTX's focus on expanding production, supporting major defense programs and developing advanced technologies. Strong demand for missile systems, radar, electronic warfare and F-35 technologies could support RTX's long-term defense growth and strengthen its position in the global aerospace and defense market.
