Read MoreHide Full Article

Key Takeaways

  • LHX announced a DoW partnership with a $1B convertible investment to expand solid rocket motor capacity.
  • LHX plans an IPO of its Missile Solutions unit in the second half of 2026 to form a focused public company.
  • LHX will scale capacity for PAC-3, THAAD, Tomahawk and Standard Missile programs to support long-term demand.

L3Harris Technologies, Inc. (LHX - Free Report) recently announced a first-of-its-kind proposed partnership with the U.S. Department of War (DoW) to significantly expand its capacity to produce solid rocket motors for critical U.S. and allied missile systems.

Under the agreement, the DoW will invest $1 billion in L3Harris’ Missile Solutions business via a convertible preferred security, which will automatically convert into common equity upon an initial public offering (IPO). L3Harris intends to pursue an IPO of the Missile Solutions unit in the second half of 2026, establishing a public company focused on delivering critical propulsion systems at unprecedented scale and speed.

Here's How the Partnership Benefits L3Harris

The proposed partnership with the DoW strengthens L3Harris’ position in the U.S. defense industrial base by securing significant government-backed capital to rapidly expand solid rocket motor capacity. The investment reduces funding risk while supporting scale-up for high-priority missile programs such as PAC-3, THAAD, Tomahawk and Standard Missile, ensuring steady long-term demand visibility.

The planned IPO creates a focused, pure-play propulsion company, sharpening operational execution and improving transparency. This structure is expected to unlock shareholder value while allowing L3Harris to retain a controlling stake and strategic influence.

Overall, the partnership enhances LHX’s growth prospects, accelerates capacity expansion, reinforces its role as a critical defense supplier and aligns the company closely with evolving U.S. defense acquisition priorities.
