German firm Helsing revealed Contra, an air-defense system pairing two interceptor missiles with AI software that sequences engagements, at under $100,000 per shot. The jet-powered AD-1 flies about 700 km/h out to 20 km, while the rocket-powered AD-2 nears 3,000 km/h for last-ditch intercepts. One contract is signed, but the system is still in testing and not expected to be market-ready until the second half of 2027.
