About Us

In 1916, Kollmorgen, a small optical company in Brooklyn, New York was contracted to design, build and install the first workable periscope aboard the first U.S. submarine. For ninety years, the company has remained devoted to high-accuracy, stabilized, electro-optical systems for defense.

L3 KEO employs a full spectrum of engineering and manufacturing disciplines to design a variety of sensor and weapon systems for submarines, surface ships, combat vehicles, and other defense platforms.

With facilities in Massachusetts and Pennsylvania, L3 KEO is an experienced developer of integrated and stabilized, high-performance optronic sensor, antenna, masts and weapon control systems for defense applications. L3 KEO has the capability to accept any electro-optical or motion control challenge and then design to it, build it, test it, and stand behind it. L3 KEO provides a wide range of technical capabilities for:

  • Motion control and stabilized systems
  • Imaging and display
  • User Interface
  • Packaging for harsh environments

Our customer focus underscores our working with U.S. and international customers to define their needs, understand their unique technical requirements and set up local support.

From the first submarine periscope to the latest optronic sensors, L3 KEO continues to translate design excellence into fielded products. L3 KEO produces the systems that enable you to look, to see, and to control the leading edge of integrated imaging systems.
