And to a new-ish company like Anduril, too! Palmer Lucky and Co founded it in 2017 which is baby years for a lead defense contractor on a major project like this.
IIUC this is the Wingman program for the F22 and F35 so these aren't "slow" drones like predators, these are going to be high performance jets. This is a serious contract!
F22 rated load is 9g continuous (~13g burst) and it's made with mostly Ti64, thermoset composites, and aluminum [1].
It's much lower than it can be because there's no point in investing in a stronger airframe when the sustained acceleration would kill any pilot. These unmanned drones can easily be designed to withstand much more.
9G shouldn't be a problem at all, from a material standpoint. Missiles go to 100G, and F1 engine pistons withstand 8.600G (https://en.m.wikipedia.org/wiki/G-force).
The F-16 avionics are limited to 9G, but the fuselage is able to handle much more when not carrying a full load of fuel. 9Gs is standard for a fighter.
