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.
