The future of air combat is drones launching more drones
On March 26, a windowless drone called the Valkyrie opened its weapon bay doors, the first time it had done so while airborne. Then, it released into the sky below not a bomb, but another, smaller drone, a scout launched into flight from its mid-air berth. Deployed from a mothership into flight, the drone-launched drone ushers in an era of machines sending other machines to fight battles for humans.
The XQ-58A Valkyrie drone, with a 28-feet length and 22-foot wingspan, was on its sixth test flight at the Yuma Proving Ground in Arizona. The Valkyrie has flown over the Sonoran desert around Yuma since 2019, it s dark gray body stark against the sun-scorched sands below.

The study includes around 900 paratroopers in the Spartan brigade.
The airborne Army brigade known as the Spartans is based in Anchorage, Alaska. “We jump out of pretty much anything that flies,” says Phil Rank, chief warrant officer with the light infantry brigade. “If it can get in the air, we can get out of it.”
Being a paratrooper in the Army and jumping out of perfectly good airplanes carries with it its own stressors, but the unit’s northern location adds an extra layer. “We don’t have the consistency of light like you do in the lower 48,” Rank observes. “We go through extreme periods of daylight, and extreme periods of darkness.” ....

The impacts of COVID-19 are going to be felt for a long time.
As the one-year anniversary of the pandemic hits us this week, we still have lots of questions about how we vaccinate against the novel disease, treat patients who are already infected, and what the future symptoms of infection could look like. After a year of research and observation, we know more than we ever have, but there’s still a lot of work to be done. And while cases still continue to be at levels comparable to previous peaks, some states are hastily easing up on protective mandates. Here’s everything you might have missed this week. ....
