Small, fast-moving U.S. tech firms are using the war in Ukraine to demonstrate a new generation of military systems but face the challenge of selling them to a risk-averse Defense Department.
Capella Space, a San Francisco-based start-up, is building a fleet of small, inexpensive satellites that can track enemy troops as they move at night, or under cloud cover that traditional optical satellites cannot see through.
Fortem Technologies, a small aerospace company in Utah, wants to supply the Pentagon with a new type of unmanned aircraft that can disable enemy drones.
HawkEye 360, a Virginia-based firm, has used private equity funds to launch its own satellites that use radio waves emitted by cellphones and other electronic devices to detect the presence of enemy troop concentrations.
Each of these systems is getting real-world testing in the war in Ukraine, earning praise from top government officials there and validating investors who have been pouring money into the field.
