Startups bring Silicon Valley ethos to a lumbering military-industrial complex

Capella Space, a San Francisco-based startup, 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 communications equipment and other electronic devices to detect the presence of enemy troop concentrations.
