Leonardo DRS is a mid-tier U.S. defense electronics company that designs, manufactures, and integrates sensors, computing systems, power systems, and force protection equipment for the U.S. military and allied forces. Rather than building major platforms like ships or aircraft, DRS supplies the electronics and systems that go inside them. The U.S. military accounts for roughly 80% of revenue, with the Navy and Army each representing about 36% of total revenue; the remaining ~20% comes from foreign government sales, primarily through Foreign Military Sales to U.S. allies. DRS operates through two segments: Advanced Sensing and Computing (ASC), which makes EO/IR sensors, tactical radars, network edge computing products, and electronic warfare systems; and Integrated Mission Systems (IMS), which designs electric power, propulsion, and force protection systems, most notably as the propulsion supplier for the Columbia Class submarine program, DRS's single largest program. DRS earns revenue under long-term U.S. government contracts, roughly 88% of which are firm-fixed-price, meaning DRS keeps cost savings but absorbs overruns. DRS acts as both a prime contractor (39% of revenue) and a subcontractor (61%), often supplying subsystems to large platform integrators. Growth priorities include counter-drone systems, advanced infrared sensing, naval electric propulsion, and space-based sensing. DRS is majority-owned by Italy's Leonardo S.p.A. but operates as a U.S. company under a proxy agreement with the DoD.
