[Endgame] why didn’t Iron Man, War Machine, or Thor intervene either time when Thanos’s ship rained fire on them? Is there any MCU vehicle or weapon besides Infinity Stones that can cause that much damage that fast?

For the first question, those 3 can fly yet neither times did they go attack the ship. Thor looked unscathed after the first blast so it’s like he was fine. Apparently War Machine had several seconds to react before going under. 

For the second question, what other vehicles or weapons in the MCU could destroy the Avengers hq that fast or faster?

They may have been pinned by bad guys or trying to prevent that from happening to their allies.  If they did fly up they’d get targeted down—Carol’s arrival proves that Sanctuary II is prepared to drop what it’s doing to focus on a high priority target.
