What are some military tech/equipment stocks that are highly scalable?

By highly scalable I mean that the company can easily increase production because either:

• Their product is mostly software based; or
• Their manufacturing process is not so complicated that they can easily double capacity; or
• They can quickly build more factories (like Tesla)

I ask because while I like stocks like LMT or HII, they generally build very bulky things like tanks and ships that isn't easy to ramp up.
