Been working this for a few months now. It’s not a crazy hard problem - but it does break the mold of distance and speed taking priority over capacity. If you have any questions feel free to ask. I can get into the pros/cons of all the various options and tuning knobs.

I'd make it 50NM. 5 is way too easy to bullshit with edge case engineering. Alternatively, set a minimum payload capacity of something like 100kg.
CATL is working on 12000 Wh/kg air batteries, they will solve this problem, give them the prize.
The military is waking up to the need to adapt frontline logistics. With killrates of 90% for traditional trucks in the Ukraine war, without resupply missions by UAVs/UGVs holding positions is impossible now.
This is being announced to us or everyone right now? It's only around 10 weeks away: that seems surprisingly close. Have some folk already been made aware & have they had time to build for this DARPA Challenges? Generally I think of them as longer running challenges.
Darpa.mil got slashdotted? Wow. The folks who invented the internet...
Really just a battery challenge.
Possibly against laws of physics at energy density of 4x?
Hate that "warfighter" has entered our vocabulary. It's so kitsch...
