This year’s Super Bowl was full of historic moments. Tom Brady securing his fifth Super Bowl ring, a Super Bowl going into overtime, and the Falcons choosing not to be any good at football anymore in the second half were all memorable, but for my money, it was the halftime show that we should really have been paying attention to.

Of course, I don’t mean because Lady Gaga dressed up as a flying Romulan from “Star Trek: The Next Generation,” nor is it because of the impressive dance choreography. The Super Bowl halftime show was important because it gave us a glimpse of how warfare will be waged in the 21st century.

The beginning and end of Lady Gaga’s performance were accented by a fleet a mini-drones—300 of them to be exact—executing their own complicated choreography in the background as the singer did her thing. The drones were not technically present for the halftime performance; the FAA actually prohibited their presence in the packed stadium as variables too numerous to list could have led to complications in their flights and even injuries to the dancers or crowd. Instead, the drones executed their intricate flight paths earlier in the week and were filmed for use in the halftime show.

Each of the 300 individual drones weighed only slightly more than a half pound and were made, according to Intel, “with a soft frame made of flexible plastics and foam.” Their construction “contains no screws.” Each drone is capable of flying to elevations in excess of 700 feet and can withstand wind speeds in excess of 10 meters per second. Because FAA restrictions prohibited the drones from performing live, the Intel team arrived in Houston a week early and filmed their portion during the best possible weather conditions.
